International Human Rights Law Explained

Introduction


International Human Rights Law is the branch of public international law that recognizes rights held principally by individuals and imposes corresponding obligations principally on states. It governs how states exercise public authority and what they must do, under the applicable legal rule, to protect dignity, liberty, equality, and basic welfare. Particular instruments also recognize rights held by groups and peoples in defined contexts. The field remains decentralized: no single global code contains every right, and no international court has universal jurisdiction over all human rights claims.


The modern legal framework took shape after the Second World War. Article 1(3) of the United Nations Charter made international cooperation in promoting respect for human rights one of the organization’s purposes, while Articles 55 and 56 linked that objective to obligations of cooperation undertaken by member states (United Nations, 1945, arts 1(3), 55–56). The Universal Declaration of Human Rights then articulated a common standard covering civil, political, economic, social, and cultural rights, but it was adopted as a General Assembly resolution rather than a treaty (United Nations General Assembly, 1948). The International Covenant on Civil and Political Rights and the International Covenant on Economic, Social and Cultural Rights later established detailed treaty obligations for their respective states parties (ICCPR, 1966; ICESCR, 1966).


Legal authority within this system depends on the source and institution. Treaty provisions, customary international law, regional court judgments, treaty-body Views, General Comments, concluding observations, and resolutions of the General Assembly or Human Rights Council do not carry the same binding force or procedural effect. Nor does the recognition of a right establish that every state is bound by it in the same manner. Treaty participation, reservations, territorial and extraterritorial jurisdiction, temporal scope, and acceptance of particular complaint procedures may all affect the legal analysis.


A human rights claim must be assessed through distinct inquiries. The relevant rule and the basis on which it binds the state come first. Jurisdiction, attribution, the content of the applicable obligation, and the existence of a breach must then be established. Any asserted restriction or emergency derogation must satisfy the requirements of the governing instrument. Questions of admissibility, remedy, institutional competence, and the authority of the resulting decision arise within their own procedural settings.


Domestic institutions remain the principal setting in which human rights obligations are implemented. International supervision may supplement national protection through reporting, expert monitoring, individual communications, commissions, or judicial proceedings, depending on the instrument, the institution’s mandate, and the procedures accepted by the state. A favorable international finding does not by itself guarantee implementation. Keeping these stages separate prevents recognition of a right from being confused with jurisdiction, breach, access to a forum, remedial authority, or actual compliance.


1. What International Human Rights Law Regulates


International Human Rights Law regulates legal relationships between persons and public authorities. It protects interests such as life, liberty, physical integrity, equality, privacy, political participation, education, health, work, and cultural life by recognizing legal rights and imposing corresponding obligations. The legal character of a claim depends on its source. An appeal to dignity or justice may be morally persuasive without constituting a binding rule of international law.


Human rights discourse consequently extends beyond human rights law. Political declarations can influence diplomatic expectations, legislation, and legal interpretation while remaining non-binding. Constitutional guarantees derive their authority from a domestic legal order. International obligations arise through treaties, customary international law, and other recognized sources, subject to their own conditions of application.


The field does not provide a remedy for every injustice or harmful exercise of power. Legal analysis must identify the protected right, its holder, the actor bearing the corresponding obligation, and the relevant material, personal, territorial, and temporal scope. Recognition of an important social interest does not answer those questions by itself.


1.1 Rights-Holders, Duty-Bearers, and Legal Capacity


Individuals are the principal rights-holders under the major international human rights treaties, while states parties are their principal treaty duty-bearers. Article 2(1) of the International Covenant on Civil and Political Rights requires each state party to respect and ensure Covenant rights to individuals within the provision’s jurisdictional scope. Article 2(1) of the International Covenant on Economic, Social and Cultural Rights requires states parties to take steps toward the realization of the rights recognized in that Covenant (ICCPR, 1966, art. 2(1); ICESCR, 1966, art. 2(1)).


Nationality is not a general condition for human rights protection. Some provisions do distinguish citizens from other persons: Article 25 of the ICCPR, for example, protects specified rights of political participation belonging to citizens. The status of the rights-holder must be determined from the wording and scope of the particular rule rather than from a presumption that every guarantee applies identically to every person (ICCPR, 1966, arts 2(1) and 25).


Not every protected right is exclusively individual. Common Article 1 of the two Covenants attributes the right of self-determination to peoples. Article 27 of the ICCPR takes a different approach by protecting persons belonging to ethnic, religious, or linguistic minorities in the communal enjoyment of their culture, religion, and language. The African Charter on Human and Peoples’ Rights recognizes a wider group of rights held by peoples, including equality, self-determination, control over natural resources, development, peace, and a satisfactory environment (ICCPR, 1966, arts 1 and 27; ICESCR, 1966, art. 1; African Charter, 1981, arts 19–24).


International legal personality does not confer a uniform set of rights and capacities. In the Reparation for Injuries advisory opinion, the International Court of Justice held that the United Nations possessed international personality and the capacities required by its functions. The Court also observed that subjects of international law need not be identical in the nature or extent of their rights (ICJ, 1949, pp. 178–179).


That general proposition must be distinguished from decisions concerning rights granted directly to individuals. In the Jurisdiction of the Courts of Danzig advisory opinion, the Permanent Court of International Justice accepted that an international agreement could create individual rights and obligations enforceable before national courts (PCIJ, 1928, p. 17). In LaGrand, the International Court held that Article 36(1) of the Vienna Convention on Consular Relations created individual rights; Germany was able to invoke those rights before the Court under the applicable interstate jurisdictional arrangement (ICJ, 2001, para. 77).


Neither decision gave individuals the general legal capacities possessed by states. A person may hold substantive rights and enjoy access to a particular domestic or international procedure without gaining a general capacity to conclude treaties, exercise diplomatic protection, bring interstate proceedings, or appear before every international tribunal.


1.2 Binding Obligations and Enforceable Claims


The existence of an international obligation, its domestic enforceability, and access to international review are separate legal questions. A treaty binds a state when it is in force for that state, subject to the treaty’s terms and any applicable reservation. Customary international law may supply an independent obligation, but its existence requires sufficiently general practice accepted as law rather than repeated assertions that a claimed right is universal.


Domestic enforceability depends on the constitutional and legal system concerned. Some treaty provisions may be applied directly by national courts. Others require implementing legislation or operate primarily as interpretive or administrative obligations. A domestic court may also enforce a constitutional right that does not correspond exactly to an international rule.


These differences do not permit a state to rely on its internal law as a justification for failing to perform a treaty. Article 27 of the Vienna Convention on the Law of Treaties preserves the distinction between the state’s obligations on the international plane and the domestic methods through which those obligations are implemented (Vienna Convention on the Law of Treaties, 1969, art. 27).


A treaty obligation to provide a domestic remedy does not necessarily create an international right of petition. Article 2(3) of the ICCPR requires states parties to ensure an effective remedy for violations of Covenant rights. The First Optional Protocol establishes a separate procedure through which individuals claiming to be victims may submit communications to the Human Rights Committee, but only against states that have accepted the Protocol and only where its procedural conditions are satisfied (ICCPR, 1966, art. 2(3); First Optional Protocol, 1966, arts 1–5).


Jurisdiction, standing, admissibility, merits, remedial authority, and implementation perform different functions. Jurisdiction concerns the institution’s legal competence over the state, subject matter, person, place, and relevant period. Standing concerns the claimant’s entitlement to bring the matter. Admissibility determines whether the claim may be examined, often through requirements concerning victim status, exhaustion of domestic remedies, time limits, or duplication. A decision on the merits then remains distinct from the remedy available and from the state’s eventual compliance.


1.3 Boundaries with Related Legal Regimes


Domestic constitutional law frequently protects interests also recognized by international human rights instruments. Both may regulate detention, equality, expression, religion, privacy, fair trial, and political participation, but their legal sources and remedies differ. A constitution may provide broader protection or formulate a right differently. Domestic authorization of particular conduct does not, however, determine whether that conduct complies with an international obligation.


International humanitarian law applies only when the legal threshold for an international or non-international armed conflict has been met. It regulates parties to the conflict and includes rules that bind qualifying non-state armed groups, notably under common Article 3 of the Geneva Conventions. Human rights treaties principally impose obligations on their state parties and continue to operate during armed conflict according to their jurisdiction, limitation, and derogation provisions. The International Court of Justice has confirmed that human rights protection does not cease merely because an armed conflict exists, although humanitarian law may provide a more specific rule for a particular question (Geneva Conventions, 1949, common art. 3; ICJ, 1996, para. 25; ICJ, 2004, para. 106).


The same killing, detention, displacement, or trial may engage both regimes. Concurrent application does not erase their differences. Humanitarian law contains rules on combatant status, targeting, prisoners of war, occupation, and the conduct of hostilities that have no general equivalent in human rights law. Human rights institutions, in turn, apply treaty-specific rules on jurisdiction, remedies, and supervision.


International refugee law has a narrower personal focus. The 1951 Refugee Convention defines the persons entitled to refugee status and prohibits their return to a territory where life or freedom would be threatened for a Convention reason, subject to the limited exceptions in Article 33(2). Human rights law may prohibit removal on other grounds. Article 3 of the Convention against Torture, for example, prohibits return where substantial grounds exist for believing that the person would face torture, regardless of whether the refugee definition is satisfied (Refugee Convention, 1951, arts 1A(2) and 33; Convention against Torture, 1984, art. 3).


International criminal law concerns the criminal responsibility of natural persons for crimes defined by international law. Under the Rome Statute, the International Criminal Court has subject-matter jurisdiction over genocide, crimes against humanity, war crimes, and the crime of aggression, subject to the Statute’s jurisdictional and admissibility requirements (Rome Statute, 1998, arts 5 and 25). Conduct may breach human rights law and also contribute to an international crime, but criminal liability requires proof of the material, contextual, and mental elements of the particular offense. A grave human rights violation is not automatically genocide, a crime against humanity, or a war crime.


International labor law overlaps with human rights law in areas including freedom of association, collective bargaining, forced labor, child labor, discrimination, and occupational safety. ILO conventions create treaty obligations for members that ratify them. The ILO Declaration on Fundamental Principles and Rights at Work, adopted in 1998 and amended in 2022, separately identifies principles and commitments associated with ILO membership. The amendment added a safe and healthy working environment to that framework; it did not make every unratified fundamental convention binding as a treaty (International Labour Organization, 1998/2022).


International organizations, corporations, and armed groups cannot be assigned one uniform legal position merely because they are described as non-state actors. An international organization may possess international legal personality and may be bound by obligations derived from its constituent instrument, agreements, customary international law, or other applicable rules. The ILC Articles on the Responsibility of International Organizations address attribution, breach, and legal consequences where an organization is already bound by a primary obligation. They are not a treaty and do not establish which human rights rules bind every organization (ILC, 2011, arts 4 and 6).


Corporations are not parties to the principal international human rights treaties. The UN Guiding Principles on Business and Human Rights distinguish the state duty to protect against business-related abuse from the corporate responsibility to respect human rights. The Guiding Principles are an influential non-binding framework. Their corporate responsibility standard must be distinguished from binding duties created by domestic legislation, contracts, labor regulation, environmental law, or other applicable legal rules (United Nations, 2011, principles 1 and 11).


Organized armed groups may be directly bound by humanitarian law when they are parties to an armed conflict. The extent to which general international human rights law imposes direct obligations on such groups remains disputed, particularly outside situations in which they exercise sustained territorial control or government-like functions. Statements and recommendations by United Nations bodies may carry institutional and practical significance without making an armed group a party to a human rights treaty.


A single event can consequently engage several legal regimes at once. Their overlap does not merge their sources, rights-holders, duty-bearers, thresholds, procedures, or consequences. The applicable law must be established for each claim rather than inferred from the seriousness of the underlying harm.


2. How the Modern Human Rights System Developed


The modern human rights system did not emerge fully formed in 1945. It drew on earlier rules governing slavery, labor, minorities, nationality, and armed conflict, then developed through wartime experience, decolonization, treaty negotiation, and regional institution-building. Governments accepted that the treatment of individuals could be regulated internationally while continuing to contest the scope of the obligations and the authority of supervisory bodies. The resulting system reflects legal innovation, diplomatic compromise, and persistent disagreement over sovereignty, economic organization, and enforcement (Fassbender and Peters, 2012; González Hauck, 2024).


2.1 Protection Before 1945


Before the United Nations, international protection was divided among separate legal regimes. Entitlement often depended on nationality, employment, minority status, territorial arrangements, or the existence of armed conflict. These regimes placed aspects of state conduct under international regulation, but they did not establish a general body of rights held by every person against the state exercising authority over them.


International agreements directed against the slave trade and slavery formed one part of this earlier history. The 1926 Slavery Convention defined slavery and required its parties to prevent and suppress the slave trade and to pursue the complete abolition of slavery progressively and as soon as possible (Slavery Convention, 1926, arts 1–2). Those commitments were significant, but abolition measures coexisted with colonial forced labor, racial hierarchy, and coercive economic systems. Humanitarian regulation and imperial domination developed within the same international order rather than in separate historical periods (Craven, 2012; Drescher and Finkelman, 2012).


The settlements following the First World War established treaty protections for certain minorities, particularly in states created or territorially altered after the war. The obligations addressed nationality, equality, religion, language, and education, and the League of Nations operated a petition procedure for their supervision. The arrangements were selective: comparable duties were not imposed uniformly on all League members, and petitioners did not possess a general right to litigate as parties before an international court. Minority protection remained tied to particular treaties and to the political hierarchy of the postwar settlement (Nijman, 2012).


A more durable institutional model appeared in the International Labour Organization. Established in 1919, the ILO connected lasting peace with social justice and brought governments, employers, and workers into its constitutional structure. Conventions and recommendations placed working conditions, forced labor, freedom of association, and related subjects within international standard-setting. Ratified conventions created treaty obligations, while reporting and representation procedures supplied forms of supervision that differed from judicial enforcement (International Labour Organization Constitution, 1919, as amended, preamble and arts 3, 7, 19, 22–24).


General international law continued to rely heavily on nationality. Diplomatic protection allowed a state to pursue an international claim based on injury to one of its nationals. In Mavrommatis Palestine Concessions, the Permanent Court of International Justice explained that a state taking up the case of its national was asserting its own right to secure respect for international law (PCIJ, 1924, p. 12). The individual’s injury generated the dispute, but the state generally controlled the international claim. The model offered limited protection to stateless persons and ordinarily did not provide a route for claims by individuals against their state of nationality.


The law of armed conflict imposed further restraints. The Hague and Geneva traditions regulated methods of warfare and protected defined categories such as the wounded and sick, prisoners of war, and inhabitants of occupied territory. Protection depended on armed conflict and on classifications specific to that body of law. It did not create a general peacetime relationship between an individual and the state exercising public authority (Hague Regulations, 1907; Geneva Convention on Prisoners of War, 1929).


These earlier arrangements should not be treated simply as incomplete versions of postwar human rights law. Each served a distinct legal purpose and contained exclusions shaped by nationality, status, reciprocity, colonial rule, or armed conflict. Their relevance lies in demonstrating that international law had begun to regulate the treatment of persons without yet recognizing a general and universal legal relationship between individuals and states.


2.2 The Charter, Covenants, and Regional Systems


The United Nations Charter changed the institutional setting by placing human rights within the purposes and responsibilities of the new organization. Article 1(3) referred to international cooperation in promoting and encouraging respect for human rights, while Articles 55 and 56 committed members to cooperate in pursuing universal respect and observance (United Nations, 1945, arts 1(3), 55–56). These provisions form part of a binding treaty, but their broad wording did not define a catalogue of rights, establish the content of each obligation, or create a general procedure for individual complaints.


The Universal Declaration of Human Rights supplied much of the substantive language absent from the Charter. Adopted by the General Assembly on 10 December 1948, it placed civil, political, economic, social, and cultural rights within one instrument and described itself as a common standard of achievement (United Nations General Assembly, 1948). It was not adopted as a treaty and did not establish a court or a complaints body. Its influence developed through later treaty drafting, constitutional law, judicial reasoning, institutional interpretation, and diplomatic practice. Any claim that a particular Declaration provision also reflects customary international law must be established separately.


Negotiating the two International Covenants required almost two decades. Disagreement concerned colonialism, self-determination, economic and social policy, implementation, and the extent of international supervision. The ICCPR and ICESCR were adopted in 1966 and entered into force in 1976. Each created treaty obligations for its states parties; neither became universally binding merely through adoption by the General Assembly. Individual communications under the ICCPR depended on the state’s separate acceptance of the First Optional Protocol (ICCPR, 1966; ICESCR, 1966; First Optional Protocol, 1966).


The Covenants formulate their general obligations differently. Article 2 of the ICCPR requires states parties to respect and ensure the protected rights and to provide an effective remedy. Article 2(1) of the ICESCR requires states parties to take steps, using the maximum of their available resources, toward progressive realization. The distinction is legally relevant but does not divide the treaties into immediately enforceable rights on one side and non-binding policy objectives on the other. Civil and political rights may require legislation, investigation, institutions, and expenditure. Under the ICESCR, the duties to take steps and to guarantee non-discrimination are of immediate effect, even though full realization of many rights may occur progressively (ICCPR, 1966, art. 2; ICESCR, 1966, art. 2; CESCR, 1990, paras 1–2).


Specialized treaty-making both preceded and followed the Covenants. The Genocide Convention was adopted in 1948, and the Convention on the Elimination of All Forms of Racial Discrimination followed in 1965. Later treaties addressed discrimination against women, torture, children’s rights, migrant workers, disability, and enforced disappearance. Each instrument defines its own obligations, institutions, and procedures. Its substantive provisions bind states parties, while individual complaints or inquiries depend on the treaty framework and any additional consent required from the state (Genocide Convention, 1948; CERD, 1965; CEDAW, 1979; Convention against Torture, 1984; CRC, 1989; Migrant Workers Convention, 1990; CRPD, 2006; CED, 2006).


Decolonization altered both the membership of international institutions and the claims advanced within them. Newly independent states adopted varied positions, but many emphasized self-determination, racial equality, opposition to apartheid, sovereign equality, economic independence, and control over natural resources. General Assembly Resolution 1514 (XV) affirmed the right of all peoples to self-determination and called for an end to colonial rule. Resolution 1803 (XVII) articulated permanent sovereignty over natural resources, while common Article 1 of the Covenants placed self-determination in treaty form for their states parties (United Nations General Assembly, 1960, paras 2 and 5; 1962; ICCPR, 1966, art. 1; ICESCR, 1966, art. 1).


The campaign against racial domination also shaped the legal order. CERD imposed treaty obligations concerning racial discrimination, and the 1973 Apartheid Convention characterized apartheid as a crime against humanity within its own treaty framework (CERD, 1965; Apartheid Convention, 1973). These developments rejected the claim that racial rule within a state or colonial territory necessarily lay beyond international scrutiny. They did not, however, remove disparities in political influence or settle later disputes concerning self-determination, secession, territorial integrity, development, and control of resources.


Regional systems emerged through different institutional paths. The European Convention on Human Rights was adopted in 1950 and entered into force in 1953. Its original structure included a Commission and a Court, but individual petition and acceptance of the Court’s compulsory jurisdiction depended on optional declarations by states. Protocol No. 11, in force from 1 November 1998, replaced that structure with a permanent Court and direct individual application. The contemporary European system should not be projected backward onto the Convention’s original design (European Convention on Human Rights, 1950, former arts 25 and 46; Protocol No. 11, 1994).


The inter-American system began differently. The American Declaration of the Rights and Duties of Man was adopted in May 1948, before the Universal Declaration, but was not a treaty. The Inter-American Court later concluded that, within the framework of the OAS Charter, the Declaration defines the human rights referred to in that Charter and is a source of international obligations for OAS member states (Inter-American Court of Human Rights, 1989, paras 41–45). The Inter-American Commission was created in 1959. The American Convention was adopted in 1969 and entered into force in 1978; the Court’s contentious jurisdiction requires recognition by the respondent state under Article 62 (American Convention on Human Rights, 1969, art. 62).


The African Charter on Human and Peoples’ Rights was adopted in 1981 and entered into force in 1986. It combined individual rights, peoples’ rights, and individual duties in a treaty shaped by decolonization, apartheid, self-determination, development, and control over natural resources. The Charter established the African Commission. A separate protocol adopted in 1998 and in force from 2004 created the African Court on Human and Peoples’ Rights (African Charter, 1981, arts 19–24; African Court Protocol, 1998).


The three regional systems are not variations of one institutional design. European protection became increasingly judicial; the inter-American framework developed through a declaration, a commission, and later treaty-based adjudication; the African Charter incorporated individual and collective guarantees reflecting the continent’s colonial and postcolonial history. Their jurisdiction, access rules, remedies, and institutional authority remain distinct.


Modern human rights law developed through overlapping instruments rather than a single constitutional settlement. Charter provisions, declarations, treaties, decolonization, and regional institutions changed the international legal position of individuals and peoples without displacing the state as the principal maker and implementer of obligations. That history accounts for the present system’s multiple sources, uneven institutional coverage, and differing degrees of legal authority.


3. Sources, Interpretation, and Legal Authority


International human rights law draws on materials that perform different legal functions. Treaties create obligations for their parties. Customary international law may bind states independently of treaty participation. Judicial decisions determine disputes within an institution’s jurisdiction, while treaty-body interpretations, declarations, and political resolutions may carry considerable authority without having the same binding effect.


Article 38 of the Statute of the International Court of Justice remains the conventional starting point for identifying sources of international law. It directs the Court to apply treaties, international custom, and general principles of law, while treating judicial decisions and the teachings of qualified publicists as subsidiary means for determining legal rules (Statute of the International Court of Justice, 1945, art. 38). It does not establish that every decision or institutional document has identical weight. The authority of a human rights instrument depends on its source, the mandate of the issuing body, the procedure followed, and the legal relationship between the state and the institution.


3.1 Treaties, Consent, and Reservations


Treaties contain the most detailed international human rights obligations. The title of an instrument—whether covenant, convention, charter, or protocol—does not determine its legal character. Under the Vienna Convention on the Law of Treaties, the relevant question is whether states concluded a written international agreement governed by international law (Vienna Convention on the Law of Treaties, 1969, art. 2(1)(a)).


Adoption of a treaty text does not bind every state. Consent to be bound may be expressed by signature, ratification, acceptance, approval, accession, or another method agreed upon by the negotiating states. Many multilateral human rights treaties require ratification after signature. Accession ordinarily allows a state that did not sign during the initial period to become a party on the treaty’s terms (Vienna Convention on the Law of Treaties, 1969, arts 11–16).


Consent and entry into force are separate. A state may ratify an instrument before it has obtained the number of ratifications required for general entry into force. The treaty becomes operative for that state according to its final clauses. A signatory whose signature remains subject to ratification is not ordinarily bound by the full substantive treaty obligations, although Article 18 requires it to refrain from acts that would defeat the treaty’s object and purpose until it has made clear that it does not intend to become a party (Vienna Convention on the Law of Treaties, 1969, arts 18 and 24).


Consent must also be established for each supplementary procedure. Optional protocols are separate treaties even when closely connected to a principal convention. They may create additional rights, establish individual communications, authorize inquiries, or introduce preventive monitoring. Ratification of the ICCPR, for example, does not by itself accept the individual communications procedure under the First Optional Protocol (First Optional Protocol to the ICCPR, 1966, arts 1–2).


Other instruments contain optional jurisdictional or procedural clauses within the principal treaty. Article 22 of the Convention against Torture permits a state to recognize the Committee against Torture’s competence to receive individual communications. Under Article 62 of the American Convention, the contentious jurisdiction of the Inter-American Court depends on state recognition. A state may consequently be bound by substantive provisions while remaining outside a particular complaint or adjudicative procedure (Convention against Torture, 1984, art. 22; American Convention on Human Rights, 1969, art. 62).


Reservations may further alter the treaty relationship. A reservation is a unilateral statement made when expressing consent to be bound through which a state seeks to exclude or modify the legal effect of specified treaty provisions in their application to that state. Article 19 of the Vienna Convention prohibits reservations excluded by the treaty, reservations outside the categories expressly permitted, and reservations incompatible with the treaty’s object and purpose. Acceptance, objection, withdrawal, and the resulting relations among parties are governed by the treaty and Articles 20 to 23 of the Convention (Vienna Convention on the Law of Treaties, 1969, arts 2(1)(d) and 19–23).


In its advisory opinion on Reservations to the Convention on the Prevention and Punishment of the Crime of Genocide, the International Court of Justice rejected the proposition that every reservation required unanimous acceptance. It treated compatibility with the Convention’s object and purpose as the central criterion, seeking to preserve both the integrity of the Convention and broad participation in it (ICJ, 1951, pp. 23–24). The opinion concerned the Genocide Convention and did not determine every consequence of an invalid reservation under later human rights treaties.


The Human Rights Committee has asserted that it may assess the compatibility of reservations to the ICCPR and has taken the position that an incompatible reservation will generally be severable, leaving the state bound without the benefit of the reservation (Human Rights Committee, 1994, paras 17–18). That severability approach is an influential interpretation of the Covenant’s regime. It is not an uncontested general rule automatically governing every multilateral treaty.


Universal wording does not remove the need to establish consent. A treaty may recognize a right belonging to “everyone,” yet its treaty obligations bind only states for which the instrument is in force, subject to its scope and any legally effective reservation. Whether the same substantive rule also binds a non-party as customary international law requires a separate inquiry.


3.2 Custom, Jus Cogens, and Erga Omnes Obligations


Customary international law does not derive its binding force from ratification. Article 38(1)(b) of the ICJ Statute describes international custom through a general practice accepted as law. The identification of a customary rule requires evidence of both sufficiently general state practice and acceptance of that practice as legally required or permitted—opinio juris (Statute of the International Court of Justice, 1945, art. 38(1)(b); ILC, 2018, conclusions 2–3).


Practice may appear in legislation, executive conduct, diplomatic correspondence, military manuals, national judgments, treaty practice, statements before international organizations, or conduct connected with disputes. Its weight depends on context, representativeness, consistency, and the states most directly concerned. Silence may be relevant only where a state was in a position to react and a response could reasonably have been expected (ILC, 2018, conclusions 5–8).


Opinio juris distinguishes legal practice from conduct motivated by courtesy, policy, morality, or political convenience. In the North Sea Continental Shelf cases, the International Court explained that even extensive and virtually uniform conduct must occur in circumstances showing a belief that the conduct is legally required (ICJ, 1969, para. 77). A human rights proposition does not become customary merely because it is frequently described as universal or fundamental.


Treaties may codify existing custom, contribute to the crystallization of an emerging rule, or support the formation of new custom through later practice accompanied by opinio juris. Widespread ratification is relevant evidence, but it does not convert every treaty provision into custom. The conduct of non-parties, reservations, implementation, official legal positions, and the reasons for state behavior remain material.


Resolutions of the General Assembly and other international bodies may contribute evidence of opinio juris or influence the development of a rule. Their language, voting record, explanations of vote, negotiations, and later state conduct must be examined. A resolution does not create customary international law solely because it received broad support or uses universal language (ILC, 2018, conclusion 12). The same caution applies to the Universal Declaration: particular guarantees may correspond to customary rules, but customary status must be established rule by rule.


Peremptory norms of general international law, or jus cogens, possess a different legal character. Article 53 of the Vienna Convention defines a peremptory norm as one accepted and recognized by the international community of states as a whole as a norm from which no derogation is permitted and which may be modified only by a later norm possessing the same character. A treaty conflicting with an existing peremptory norm is void. If a new peremptory norm emerges, an existing conflicting treaty becomes void and terminates under Article 64 (Vienna Convention on the Law of Treaties, 1969, arts 53 and 64).


The International Law Commission’s 2022 conclusions require that the rule first be a norm of general international law and that its peremptory character be accepted and recognized by the international community of states as a whole (ILC, 2022, conclusions 3–7). These conclusions provide an influential non-treaty framework for identification and consequences. They do not dispense with examination of the underlying treaties, practice, and case law.


Peremptory status must not be inferred from treaty terminology alone. A right does not become jus cogens merely because it is widely ratified, described as fundamental, or made non-derogable during a public emergency. Treaty non-derogability governs suspension under the particular instrument. Jus cogens concerns the hierarchical status of a norm of general international law and its effect on conflicting rules.


Obligations erga omnes answer another question: to whom an obligation is owed. In Barcelona Traction, the International Court distinguished ordinary interstate obligations from obligations owed to the international community as a whole, in whose protection all states have a legal interest. It referred to the prohibitions of aggression and genocide and to principles and rules concerning basic rights of the human person, including protection from slavery and racial discrimination (ICJ, 1970, paras 33–34). The Court did not state that every international human rights obligation is owed erga omnes.


The source and status of an obligation must remain distinct. An obligation erga omnes is not necessarily peremptory. The ILC has stated that peremptory norms give rise to obligations owed to the international community as a whole, but the reverse does not automatically follow (ILC, 2022, conclusion 17).


Obligations erga omnes partes arise within certain treaty regimes where all parties have a common interest in compliance. In Questions Relating to the Obligation to Prosecute or Extradite, the Court held that the relevant obligations under the Convention against Torture were owed by each state party to all other parties. Belgium could invoke Senegal’s responsibility without establishing a special injury of its own (ICJ, 2012, paras 68–70).


These classifications affect the invocation of responsibility, but they do not themselves create jurisdiction for an international court. The Court has distinguished the community-wide character of an obligation from the separate requirement of consent to jurisdiction (ICJ, 1995, para. 29; ICJ, 2006, para. 64). Nor do erga omnes or jus cogens status automatically grant individuals access to an international complaints mechanism.


One substantive prohibition may operate in several legal forms. It may bind a state under a treaty, exist independently as custom, possess peremptory status, and generate obligations beyond an ordinary bilateral relationship. Each proposition requires its own evidence and carries different consequences.


3.3 Treaty Interpretation and Institutional Authority


Human rights treaties are interpreted through the general rules of treaty interpretation. Article 31 of the Vienna Convention requires good-faith interpretation according to the ordinary meaning of the terms in their context and in light of the treaty’s object and purpose. Context includes the text, preamble, annexes, and qualifying agreements or instruments connected with the treaty’s conclusion (Vienna Convention on the Law of Treaties, 1969, art. 31(1)–(2)).


Article 31 establishes an integrated inquiry rather than a choice between literal and purposive methods. Ordinary meaning must be read in context, while object and purpose cannot be used as an independent license to replace the agreed text. Article 31(3) also requires consideration of subsequent agreements, subsequent practice establishing the parties’ agreement concerning interpretation, and relevant rules of international law applicable in relations between the parties.


Preparatory work and the circumstances of conclusion are supplementary means under Article 32. They may confirm a meaning reached under Article 31 or assist where the interpretation remains ambiguous, obscure, manifestly absurd, or unreasonable. Negotiating history is not automatically decisive, especially when it records competing proposals rather than a common intention (Vienna Convention on the Law of Treaties, 1969, art. 32).


Some human rights courts interpret treaty language in light of changing social and factual conditions. In Tyrer v United Kingdom, the European Court described the European Convention as a “living instrument” to be interpreted in present-day conditions (ECtHR, 1978, para. 31). That doctrine belongs to the jurisprudence of the European Convention system. It should not be treated as a free-standing authority allowing every institution to update every treaty without regard to text, context, consent, and institutional competence.


The legal effect of judicial decisions also depends on the governing instrument. Article 59 of the ICJ Statute provides that an ICJ judgment binds only the parties and only in respect of the particular case. Its reasoning may nonetheless influence later courts and legal arguments (Statute of the International Court of Justice, 1945, art. 59).


Regional human rights judgments derive their binding force from their own treaties. States undertake to abide by final judgments of the European Court in cases to which they are parties. Comparable duties apply to judgments of the Inter-American and African Courts within their respective treaty frameworks (European Convention on Human Rights, 1950, art. 46; American Convention on Human Rights, 1969, art. 68(1); African Court Protocol, 1998, art. 30). A judgment from one regional system may be persuasive elsewhere, but it does not bind states outside the applicable treaty relationship.


Advisory opinions have a different procedural character. They answer legal questions submitted under an institution’s advisory jurisdiction and do not ordinarily determine the responsibility of a respondent state or award reparation to an identified victim. Their interpretation may still carry substantial authority because it is issued by a judicial body acting within its mandate. The precise effect depends on the court’s constitutive instrument and the question submitted.


UN treaty bodies are committees of independent experts rather than international courts. General Comments and General Recommendations explain treaty provisions and recurring implementation questions. They do not amend the treaty and are not formally equivalent to judicial judgments. Their persuasive authority depends on the committee’s mandate and expertise, the quality and consistency of its reasoning, conformity with accepted interpretive rules, and reception by states and courts.


A General Comment is not, by itself, subsequent practice establishing the agreement of the parties under Article 31(3)(b) of the Vienna Convention. State acceptance, consistent implementation, express responses, and related conduct may contribute to such an agreement. Silence after the adoption of a committee interpretation cannot automatically be treated as the consent of every state party.


Treaty-body Views arise from individual communications procedures accepted by the state concerned. They may address admissibility, merits, remedies, and follow-up. The Human Rights Committee has characterized its Views as authoritative determinations made by the body established under the ICCPR and entrusted with interpreting and applying it (Human Rights Committee, 2008, paras 11–15).


That description does not make Views formally identical to judgments of an international court. Their precise legal effect remains debated, and the First Optional Protocol does not create the same enforcement structure as a regional court treaty. In Ahmadou Sadio Diallo, the International Court stated that it was not legally bound by the Human Rights Committee’s interpretations but should give them great weight because the Committee was established specifically to supervise the application of the ICCPR (ICJ, 2010, paras 66–67).


Concluding observations perform another function. They follow the examination of a state report and identify positive developments, concerns, and recommended measures. They may carry interpretive and political influence, but they do not adjudicate an individual claim. Recommendations by special procedures and other expert mechanisms likewise require assessment according to their mandate, evidence, methods, and institutional basis.


General Assembly and Human Rights Council resolutions are ordinarily non-binding political or recommendatory instruments. A resolution may restate existing legal obligations, contribute evidence relevant to custom, interpret an institutional mandate, or establish a subsidiary mechanism within the adopting organ’s powers. Its legal significance cannot be inferred merely from the importance of its subject or the size of the supporting majority.


The Universal Declaration remains the principal example of a non-treaty text with exceptional legal influence. Its provisions have shaped treaties, constitutional law, judicial reasoning, and diplomatic practice. That influence does not transform the Declaration into a ratified convention. Where one of its guarantees also binds through treaty or custom, the binding force arises from that independent legal basis.


Legal authority must be assessed through classification rather than institutional reputation. The relevant questions are who adopted the material, under what legal power, through which procedure, for which parties, and with what intended effect. A binding rule, an authoritative interpretation, a persuasive recommendation, and a political commitment may support the same argument, but they cannot be treated as interchangeable.


4. Rights and the Obligations They Create


International human rights law does more than identify interests deserving protection. Each right establishes a legal relationship between a rights-holder and a duty-bearer. The state may be required to refrain from interference, protect individuals against private harm, adopt legislation and institutions, investigate violations, or provide an effective remedy. The precise duty depends on the applicable treaty, the wording of the right, and the circumstances in which it operates.


The familiar distinction among duties to respect, protect, and fulfill can help classify these obligations. Respect generally requires non-interference. Protection concerns measures against harm caused by private actors. Fulfillment may require legislation, public institutions, services, or financial measures. The framework is analytical rather than a uniformly codified rule found in every treaty, and it cannot replace the interpretation of the particular provision.


4.1 Civil and Political Rights


Civil and political rights protect life, bodily integrity, liberty, fair process, private life, conscience, expression, peaceful assembly, association, and participation in public affairs. These rights are sometimes described mainly as restraints on state action, but many also require legislation, safeguards, investigations, courts, or other public institutions. Article 2 of the ICCPR requires states parties to respect and ensure Covenant rights and to provide an effective remedy for violations (ICCPR, 1966, art. 2).


The right to life prohibits arbitrary deprivation rather than every death connected with state action. Its application may require examination of the legal basis for force, necessity, proportionality, precautions, and the surrounding circumstances. States may also be required to take reasonable measures against foreseeable threats to life and to investigate potentially unlawful deaths effectively (ICCPR, 1966, art. 6; Human Rights Committee, 2018, paras 7, 18 and 27).


Some prohibitions admit no justification. Article 7 of the ICCPR prohibits torture and cruel, inhuman, or degrading treatment, while Article 4(2) excludes Article 7 from emergency derogation. The two propositions should remain distinct. An absolute prohibition concerns whether the conduct can ever be justified; non-derogability concerns whether the obligation may be suspended during a qualifying emergency.


Other rights contain express limitation clauses. Freedom to have or adopt a religion or belief is protected without the limitation applicable to its external manifestation. Manifestation may be restricted only under Article 18(3). Expression, peaceful assembly, and association are governed by their own treaty clauses, which identify permitted purposes and conditions for restrictions (ICCPR, 1966, arts 18, 19, 21 and 22). The precise analysis belongs to the applicable instrument rather than to a single universal formula.


Liberty and fair-trial guarantees depend heavily on procedure. Article 9 prohibits arbitrary arrest and detention, requires reasons for arrest, and provides for judicial review of detention. Article 14 protects equality before courts, an independent and impartial tribunal, the presumption of innocence, adequate facilities for the defense, and other safeguards in criminal proceedings (ICCPR, 1966, arts 9 and 14). These procedures are not secondary to the right; they are part of the protection itself.


Political participation has a narrower personal scope than many other Covenant rights. Article 25 protects citizens’ rights to participate in public affairs, vote and be elected at genuine periodic elections, and have access on general terms of equality to public service. States retain authority to regulate electoral systems and eligibility, but restrictions must not be unreasonable or discriminatory (ICCPR, 1966, art. 25).


Civil and political rights may also require protection against private conduct. Privacy rules may call for regulation of private data processing or surveillance. Freedom of expression and assembly may require reasonable protection against violence intended to silence journalists, protesters, or associations. The extent of such duties depends on the right, the foreseeability of the harm, the state’s knowledge, and the measures reasonably available.


4.2 Economic, Social, and Cultural Rights


The ICESCR recognizes rights relating to work, just and favorable working conditions, trade unions, social security, family protection, an adequate standard of living, health, education, and cultural life (ICESCR, 1966, arts 6–15). Food and housing are expressly included within the right to an adequate standard of living. Water is not named as a separate right in the Covenant, but the Committee on Economic, Social and Cultural Rights has interpreted it as falling within Articles 11 and 12 (CESCR, 2002, paras 2–3).


Article 2(1) requires states parties to take steps, using the maximum of their available resources, toward the progressive realization of Covenant rights. Progressive realization recognizes that full implementation may require time, expenditure, and institutional development. It does not make the rights optional or allow indefinite inaction.


Some duties apply immediately. States must begin taking deliberate measures toward implementation, and they must guarantee that Covenant rights are exercised without discrimination. The prohibition of discrimination in Article 2(2) is not postponed until a state has achieved full realization of every substantive right (ICESCR, 1966, art. 2; CESCR, 1990, paras 1–2).


Resources affect the assessment of compliance, but scarcity is not a complete answer. Relevant questions include whether the state adopted concrete measures, used available resources reasonably, avoided discriminatory allocation, and gave adequate priority to protected interests. The Covenant does not prescribe one economic system, budget, or model of public service. It does require policies and decisions to be assessed against the obligations the state has accepted.


The Committee has interpreted the Covenant as requiring minimum essential levels of each right and has stated that deliberately retrogressive measures demand careful justification (CESCR, 1990, paras 9–10). Neither “minimum core” nor a general prohibition of retrogression appears in those terms in the treaty text. They are influential interpretive doctrines whose application depends on the right, the evidence, the state’s resources, and the circumstances surrounding the measure.


Progressive realization does not mean that every incomplete social outcome constitutes a violation. The right to health does not guarantee freedom from illness, and the right to work does not guarantee a particular job. Legal scrutiny focuses on the measures taken, discriminatory exclusion, arbitrary denial of established benefits, failures to act, and any inadequately justified regression.


Economic, social, and cultural rights also contain elements of freedom. The right to work protects access to freely chosen or accepted work rather than state assignment of employment. Cultural rights protect participation, access, identity, and creative interests. Education must be accessible, but it must also be directed toward objectives identified in the Covenant, including the development of human personality and dignity (ICESCR, 1966, arts 6, 13 and 15).


4.3 Equality, Specialized Treaties, and Peoples’ Rights


Equality and non-discrimination operate both as principles governing the enjoyment of other rights and as autonomous guarantees. The ICCPR requires Covenant rights to be secured without prohibited discrimination and equally for men and women. Article 26 separately guarantees equality before the law and equal protection of the law, so a discrimination claim need not always depend on a violation of another Covenant right (ICCPR, 1966, arts 2, 3 and 26). The ICESCR contains corresponding guarantees concerning its substantive rights (ICESCR, 1966, arts 2(2) and 3).


Differential treatment is not automatically discriminatory. The inquiry concerns the ground, purpose, effect, and justification of the distinction under the applicable instrument. A rule may be discriminatory in effect even if it is neutral in form. Different treatment may also be lawful, or required, where it addresses material disadvantage or structural exclusion.


Specialized treaties respond to forms of harm that broad equality clauses did not adequately prevent. CERD defines and prohibits racial discrimination. CEDAW addresses discrimination against women in public and private life. The Convention on the Rights of the Child adapts human rights obligations to the status and evolving capacities of children. The CRPD emphasizes equality, autonomy, accessibility, inclusion, and reasonable accommodation for persons with disabilities (CERD, 1965; CEDAW, 1979; CRC, 1989; CRPD, 2006).


These instruments do more than repeat general rights for selected groups. They identify institutional barriers, stereotypes, dependence, exclusion, and discriminatory practices that affect how rights are enjoyed. Their methods differ. Temporary special measures under CEDAW, special measures under CERD, and reasonable accommodation under the CRPD have distinct treaty bases and should not be treated as one general exception to equality.


Certain international rights are attributed to people. Common Article 1 of the ICCPR and ICESCR recognizes the right of all peoples to self-determination and to pursue their economic, social, and cultural development. The African Charter recognizes additional peoples’ rights concerning existence, equality, natural resources, development, peace, and the environment (ICCPR, 1966, art. 1; ICESCR, 1966, art. 1; African Charter, 1981, arts 19–24).


Indigenous rights combine individual and collective protection. Indigenous persons possess the general rights recognized in universal and regional instruments, while instruments such as the United Nations Declaration on the Rights of Indigenous Peoples address collective identity, institutions, culture, lands, resources, participation, and consultation. UNDRIP is a General Assembly declaration rather than a treaty, although its provisions may influence interpretation and may overlap with rules derived from other legal sources. ILO Convention No. 169 creates treaty obligations only for states parties to that Convention (United Nations General Assembly, 2007; ILO Convention No. 169, 1989).


Minority rights are structured differently. Article 27 of the ICCPR protects persons belonging to ethnic, religious, or linguistic minorities in the communal enjoyment of culture, religion, and language. Minority rights, Indigenous rights, and self-determination may intersect, but they are not interchangeable legal categories.


4.4 Positive Duties and Private Harm


A state may violate human rights through direct conduct or by failing to take measures required by the applicable obligation. The Human Rights Committee has interpreted the ICCPR duty to ensure rights as requiring appropriate protection against certain acts committed by private persons or entities (Human Rights Committee, 2004, para. 8).


Positive duties may include criminalizing serious abuse, regulating dangerous activities, protecting persons facing known risks, investigating credible allegations, and providing effective remedies. There are no unlimited guarantees that no private harm will occur. The legal question is whether the state took the measures reasonably required by the right in the circumstances.


In Velásquez Rodríguez v Honduras, the Inter-American Court distinguished conduct directly attributable to the state from responsibility arising through a failure of due diligence. It held that an act initially committed by a private person could engage state responsibility where the authorities failed to prevent the violation or respond to it as required by the American Convention (Inter-American Court of Human Rights, 1988, paras 172–176). The judgment is a leading authority within the Inter-American system; its formulation should not be assumed to govern every treaty regime in identical terms.


Attribution and positive obligations answer different questions. Private conduct becomes state conduct only where a recognized rule of attribution applies, such as the exercise of governmental authority or action under state instructions, direction, or control. Where attribution is absent, responsibility may still arise from the state’s own failure to regulate, protect, investigate, or remedy.


Corporations are not parties to the principal international human rights treaties. The UN Guiding Principles on Business and Human Rights distinguish the state duty to protect against business-related abuse from the corporate responsibility to respect human rights. The latter is a non-binding standard, although domestic legislation and other legal regimes may impose binding corporate duties (United Nations, 2011, principles 1 and 11–15).


The position of other non-state actors varies. Armed groups may be directly bound by international humanitarian law when they are parties to an armed conflict. The direct application of general human rights obligations to such groups remains contested, especially where they do not exercise sustained territorial control or government-like functions. International organizations may be bound through their constituent instruments, agreements, customary rules, or other applicable law, but their obligations cannot simply be inferred from treaties concluded by states.


The respect–protect–fulfill framework helps organize these relationships, but it does not determine the result. The source and content of the right, the nature of the risk, the state’s knowledge, and the measures reasonably available remain decisive.


5. Jurisdiction, Attribution, and State Responsibility


Human rights jurisdiction determines whether a person or situation falls within the scope of a state’s obligation. Attribution asks whether particular conduct is legally treated as conduct of that state. Breach concerns whether the attributable act or omission conformed to the applicable rule. Causation may connect the conduct to a protected injury, while state responsibility describes the legal position that follows once attribution and breach are established. These questions may arise from the same facts, but they perform different functions.


Jurisdiction under a human rights treaty must also be distinguished from the jurisdiction of a court or committee. A person may fall within a state’s substantive human rights jurisdiction even though no international institution has competence to hear the claim. Conversely, a body’s competence over a state does not establish that the affected person was within that state’s jurisdiction for purposes of the substantive right.


5.1 Territory and Extraterritorial Jurisdiction


Territory remains the ordinary basis of human rights jurisdiction. Persons within a state’s territory generally fall within its jurisdiction regardless of nationality or immigration status. The relevant connection may arise in prisons, border facilities, territorial waters, and other places where public authorities exercise state power. The precise threshold depends on the wording and interpretation of the applicable instrument.


Article 2(1) of the ICCPR requires each state party to respect and ensure Covenant rights to individuals “within its territory and subject to its jurisdiction.” The Human Rights Committee has interpreted the Covenant as applying in some extraterritorial situations. In López Burgos v Uruguay, it found that a man abducted and detained in Argentina by Uruguayan agents came within Uruguay’s jurisdiction in relation to the alleged violations (Human Rights Committee, 1981, paras 12.1–12.3).


General Comment No. 31 states that Covenant rights must be secured to persons within a state party’s power or effective control even outside its territory (Human Rights Committee, 2004, para. 10). That formulation is the Committee’s interpretation rather than language expressly contained in Article 2(1), and its breadth has not been accepted uniformly by states. The International Court of Justice nevertheless concluded in the Wall advisory opinion that the ICCPR applies to acts performed by a state in the exercise of its jurisdiction outside its territory (ICJ, 2004, paras 108–111).


Article 1 of the European Convention requires contracting states to secure Convention rights to persons “within their jurisdiction.” The European Court regards jurisdiction as primarily territorial. Extraterritorial jurisdiction may arise where a state exercises effective control over an area abroad or where state agents exercise authority and control over an individual. It may also arise when officials exercise public powers abroad with the territorial state’s consent, invitation, or acquiescence (Banković and Others v Belgium and Others, 2001, paras 59–82; Al-Skeini and Others v United Kingdom, 2011, paras 130–142).


Effective control over foreign territory does not establish lawful sovereignty or validate occupation or annexation. It identifies the factual authority required for the Convention to apply. Detention, arrest, transfer, and physical custody abroad provide clearer examples of state-agent authority. Military operations that affect persons without placing them or the territory under state control present more difficult questions, and European jurisprudence does not treat every harmful extraterritorial act as an exercise of jurisdiction.


The Inter-American Court has adopted a broader position concerning transboundary environmental harm. In Advisory Opinion OC-23/17, it stated that persons outside a state’s territory may fall within that state’s jurisdiction where the state effectively controls the activity causing the harm and a causal link connects that activity to the impairment of Convention rights abroad (Inter-American Court of Human Rights, 2017, paras 95–103). Advisory Opinion OC-32/25 reaffirmed that approach in the context of the climate emergency (Inter-American Court of Human Rights, 2025, paras 277–278). Both are advisory interpretations of the Inter-American system, not findings of responsibility against a respondent state in contentious proceedings.


The Committee on the Rights of the Child adopted a related jurisdictional test in the Sacchi climate communications. It is considered that children abroad could fall within a state’s jurisdiction where that state effectively controlled the sources of emissions and a sufficient causal link existed between its conduct and the alleged harm. The communications were nevertheless inadmissible because domestic remedies had not been exhausted (Committee on the Rights of the Child, 2021, paras 10.7–10.21).


The European Court declined to extend Convention jurisdiction on that basis in Duarte Agostinho and Others v Portugal and 32 Others. It rejected extraterritorial jurisdiction over the applicants in relation to the 32 states other than Portugal. The claim against Portugal fell within the territorial jurisdiction but was inadmissible for failure to exhaust domestic remedies (ECtHR, 2024).


Transboundary effects consequently do not generate one settled jurisdictional test across international human rights law. The result depends on the treaty language, the institution’s jurisprudence, control over persons, territory, or activities, and any required causal relationship. Effective control over foreign territory or custody of an individual remains more firmly established than jurisdiction based solely on emissions, surveillance, economic influence, or other remote effects.


5.2 Attribution of Conduct to the State


Jurisdiction does not determine whose conduct is legally treated as state conduct. Attribution is governed principally by the general law of state responsibility and any more specific rule applicable in the human rights regime concerned.


The ILC Articles on Responsibility of States for Internationally Wrongful Acts provide the principal general framework. They are not a treaty, although several provisions reflect customary international law. Article 2 identifies two basic elements of an internationally wrongful act: conduct attributable to the state and a breach of an international obligation binding upon it (ILC, 2001, art. 2).


The conduct of a state organ is attributable to the state regardless of whether the organ performs legislative, executive, judicial, military, police, or other functions. Its position within the national structure is irrelevant. Conduct by regional authorities, courts, prison officials, intelligence agencies, or armed forces may therefore engage the state’s responsibility (ILC, 2001, art. 4).


An entity that is not formally a state organ may also engage responsibility where domestic law empowers it to exercise elements of governmental authority and it acts in that capacity. The rule may apply, for example, to an entity entrusted with detention, regulation, or other public powers. Legal empowerment and the governmental character of the conduct must both be established (ILC, 2001, art. 5).


Attribution is not defeated merely because an organ or empowered entity exceeded its authority or disobeyed instructions. Conduct performed in an official capacity remains attributable even when it was unlawful under domestic law or contrary to governmental orders (ILC, 2001, art. 7).


Private conduct is attributable on narrower grounds. Article 8 covers conduct carried out on a state’s instructions or under its direction or control. Financial support, political sympathy, equipment, or training does not by itself establish attribution. When applying the general law of responsibility, the International Court has required effective control over the particular operation or conduct in which the alleged violation occurred (Military and Paramilitary Activities in and against Nicaragua, 1986, para. 115; Application of the Genocide Convention, 2007, paras 398–407).


The expression “effective control” also appears in tests for territorial jurisdiction and military occupation, but it does not perform the same legal function in every context. Control sufficient to bring territory within a human rights treaty’s jurisdiction does not automatically establish that every act committed there by a private group is attributable to the controlling state.


A state may also acknowledge and adopt private conduct as its own under Article 11. Mere approval, political support, or praise after the event is insufficient. The state must acknowledge and adopt the relevant conduct as state conduct (ILC, 2001, art. 11).


Attribution must remain separate from positive obligations. Abuse by a corporation, family member, criminal organization, or armed group is not automatically attributable to the state. The state may still breach its own duty by failing to regulate, prevent, investigate, punish, or remedy private harm where the applicable human rights rule requires those measures. In such a case, responsibility rests on the state’s own act or omission rather than on automatic attribution of the original private conduct.


5.3 Acts, Omissions, Causation, and Time


State conduct may consist of an action or an omission. A breach occurs when attributable conduct fails to conform to an obligation binding on the state at the relevant time (ILC, 2001, arts 2 and 12–13). Domestic legality does not resolve that international question.


An omission can constitute a breach only where the applicable rule required action. The occurrence of private violence, environmental damage, or another harmful result does not by itself establish state responsibility. The governing obligation may require proof that authorities knew or should have known of the risk, possessed a reasonable opportunity to respond, and failed to take measures required by the applicable standard.


Positive obligations do not ordinarily impose strict liability for every injury within a state’s jurisdiction. The required measures depend on the right, the severity and foreseeability of the danger, the state’s knowledge, the vulnerability of the persons affected, and the practical means available. Different courts and treaty bodies formulate these standards differently.


Causation has no single function or universal test across human rights law. The general elements stated in Article 2 of the ILC Articles are attribution and breach, not a separate requirement of injury or causation in every case. A causal link may nevertheless form part of the primary obligation, the jurisdictional test, victim status, or the determination of reparation.


Where several states or private actors contribute to one harm, sole causation is not always required. The necessary connection may be framed through direct causation, material contribution, foreseeability, control, or failure to take reasonable preventive measures. The relevant standard must be derived from the right and institution concerned rather than assumed from the seriousness of the outcome.


Temporal jurisdiction requires the obligation to have bound the state when the legally relevant conduct occurred. Article 28 of the Vienna Convention establishes a general presumption against retroactive treaty application unless a different intention appears. Article 13 of the ILC Articles similarly provides that conduct cannot breach an obligation unless the state was bound by it at the time (Vienna Convention on the Law of Treaties, 1969, art. 28; ILC, 2001, art. 13).


A completed act must be distinguished from a continuing breach. The consequences of an earlier event may persist without converting the act into an ongoing violation. A continuing breach lasts for as long as the conduct remains incompatible with the obligation. Unlawful detention may continue after a treaty enters into force, while a completed dismissal or confiscation does not necessarily remain open to international review merely because its effects continue (ILC, 2001, art. 14).


Some breaches arise through an accumulated course of conduct rather than one isolated act. Article 15 addresses composite acts in which a series of actions or omissions, considered together, constitutes the internationally wrongful act. This may be relevant where the primary rule concerns systematic discrimination, persecution, or another pattern-based violation (ILC, 2001, art. 15).


Procedural duties may sometimes remain capable of examination even where the event giving rise to them occurred before the institution acquired temporal competence. The European Court has held that the duty to investigate a death can, in limited circumstances, be sufficiently independent from the original event to fall within the Convention’s temporal scope. Its approach requires a genuine connection with the post-entry period and does not permit unrestricted reopening of historical events (Šilih v Slovenia, 2009, paras 159–163; Janowiec and Others v Russia, 2013, paras 140–151).


Once attribution and breach have been established, state responsibility may entail cessation and reparation. Those consequences do not collapse the preceding inquiries. Jurisdiction determines the reach of the human rights obligation; attribution identifies state conduct; breach compares that conduct with the applicable rule; and causation links the wrongful act to any injury for which reparation is sought.


6. Limitations, Derogations, and Armed Conflict


Not every interference with a protected right constitutes a violation. Some rights prohibit defined conduct without permitting justification. Others allow restrictions under conditions contained in the governing treaty. During a qualifying emergency, certain treaties also permit temporary derogation from specified obligations. Armed conflict raises a further question concerning the concurrent application of human rights law and international humanitarian law.


These legal structures are distinct. A limitation operates within the normal scope of a right. Derogation permits an exceptional departure from an obligation under a treaty that expressly authorizes it. International humanitarian law applies when the factual and legal threshold for an armed conflict is satisfied, regardless of whether a state has proclaimed an emergency or entered a derogation.


6.1 Absolute Rights and Lawful Limitations


The wording of the right determines whether an interference can be justified. Some provisions contain express limitation clauses. Others incorporate standards such as arbitrariness, lawfulness, or reasonableness into the definition of the right. A smaller category prohibits conduct without allowing the state to justify it by reference to public security, necessity, or proportionality.


The prohibition of torture is the clearest example. Article 7 of the ICCPR and Article 3 of the European Convention contain no limitation clause permitting torture or cruel, inhuman, or degrading treatment. Article 7 is also excluded from derogation under Article 4(2) of the ICCPR. Absoluteness concerns whether the prohibited conduct can ever be justified; non-derogability concerns whether a treaty obligation may be suspended during an emergency (ICCPR, 1966, arts 4(2) and 7; European Convention on Human Rights, 1950, art. 3).


The categories do not always coincide. Article 18 of the ICCPR is non-derogable, but it distinguishes the freedom to have or adopt a religion or belief from the freedom to manifest it. Coercion impairing the former is prohibited, while manifestation may be restricted under Article 18(3). Non-derogability, therefore, does not remove limitations already contained within the provision.


Freedom of movement, expression, peaceful assembly, association, and manifestation of religion are qualified under the ICCPR. The European Convention contains related limitation clauses for private and family life, religion, expression, assembly, and association. Their wording and permitted aims differ, so compliance with one provision does not establish compliance with another (ICCPR, 1966, arts 12(3), 18(3), 19(3), 21 and 22(2); European Convention on Human Rights, 1950, arts 8–11).


A restriction must first satisfy the legality requirement used by the applicable clause. The authorizing rule should be accessible and sufficiently precise to guide conduct and constrain official discretion. The existence of a broad domestic power does not by itself establish that an interference was prescribed by law or imposed in conformity with law.


The state must also identify an aim permitted by the provision. Depending on the right, these may include national security, public safety, public order, health, morals, or the rights and freedoms of others. Treaty lists cannot be enlarged merely because a government considers another objective socially useful.


Necessity requires a genuine connection between the restriction and the permitted aim. A measure that is merely convenient, symbolic, or politically desirable does not satisfy that requirement. The availability of a less restrictive but comparably effective measure may indicate that the interference was unnecessary.


Proportionality examines whether the burden imposed on the right is excessive in relation to the legitimate objective. Relevant considerations may include the measure’s scope, duration, penalties, exceptions, affected population, and practical consequences. Notice, reasons, independent authorization, judicial review, and periodic reconsideration may also be necessary safeguards against arbitrariness.


These elements appear across several systems, but they are not applied through one universal test. The European Court asks whether certain restrictions are necessary in a democratic society and may allow states a margin of appreciation subject to international review. ICCPR bodies derive the permissible restriction from the wording of the particular Covenant article. The American Convention contains its own limitation provisions and a general rule in Article 30 concerning restrictions authorized by the Convention. Each analysis must remain tied to the applicable instrument.


6.2 Public Emergencies and Derogation


Derogation is an exceptional treaty mechanism for circumstances in which ordinary limitations are insufficient. It does not suspend the treaty as a whole or grant unrestricted emergency powers. A state may derogate only where the relevant treaty authorizes it, and every substantive and procedural condition has been satisfied.


Article 4 of the ICCPR requires a public emergency threatening the life of the nation. The emergency must be officially proclaimed. Measures may extend only as far as strictly required by the situation, must remain consistent with the state’s other international obligations, and must not discriminate solely on the grounds listed in Article 4(1) (ICCPR, 1966, art. 4).


Article 15 of the European Convention applies in time of war or another public emergency threatening the life of the nation. Article 27 of the American Convention refers to war, public danger, or another emergency threatening the independence or security of the state party. Their notification requirements and lists of non-derogable guarantees differ. The ICESCR and the African Charter contain no comparable general derogation clause.


In Lawless v Ireland, the European Court described a public emergency threatening the life of the nation as an exceptional crisis affecting the population and threatening the organized life of the community (ECtHR, 1961, para. 28). Terrorism, armed violence, civil disorder, epidemics, or natural disasters may satisfy a treaty threshold, but their seriousness does not make that conclusion automatic. The state must demonstrate that the conditions stated in the applicable instrument existed.


Strict necessity applies to each derogating measure. The government must justify why the particular departure was required, how broadly it operated, whom it affected, and how long it remained necessary. Emergency powers cannot become permanent merely because some degree of danger continues.


A derogating measure must also comply with the state’s other international obligations. Conduct permitted under one treaty’s emergency clause may remain prohibited by another human rights treaty, international humanitarian law, refugee law, or a peremptory rule. Domestic emergency legislation cannot determine compliance with those independent obligations.


Non-derogable guarantees vary among treaties. Article 4(2) of the ICCPR lists Articles 6, 7, 8(1) and 8(2), 11, 15, 16, and 18. The European and American Conventions use different lists. Non-derogability does not alter the internal structure of the right: Article 6 of the ICCPR continues to prohibit arbitrary deprivation of life, while Article 18 continues to permit restrictions on manifestation under Article 18(3).


The Human Rights Committee has also concluded that some obligations not expressly listed in Article 4(2) contain elements that cannot lawfully be suspended, particularly where peremptory norms or procedural guarantees necessary to protect non-derogable rights are involved. This is an authoritative institutional interpretation of the ICCPR, not a rule that can automatically be transferred to every regional treaty (Human Rights Committee, 2001, paras 11 and 15).


Notification is a separate treaty requirement. Under Article 4(3) of the ICCPR, the state must notify other states parties through the UN Secretary-General of the provisions affected and the reasons for the derogation. The European and American Conventions require notification through their respective secretaries-general. The existence of a domestic proclamation does not replace international notification.


International supervision continues during the emergency. A court or treaty body may examine whether the threshold existed, whether the derogation was properly notified, and whether each measure was strictly required, non-discriminatory, and consistent with the rights that remained operative.


6.3 Human Rights Law During Armed Conflict


Armed conflict does not terminate international human rights obligations. International humanitarian law applies when the criteria for an international or non-international armed conflict are met. Human rights treaties continue to operate according to their jurisdictional provisions, substantive guarantees, and any valid derogation. Both bodies of law may therefore govern the same person, territory, or conduct.


Their scope is not identical. Humanitarian law regulates parties to armed conflict and contains rules concerning targeting, military objectives, prisoners of war, occupation, and the treatment of persons taking no active part in hostilities. Human rights treaties principally regulate the obligations of their state parties and contain distinct rules on jurisdiction, remedies, and international supervision.


In the Nuclear Weapons advisory opinion, the International Court of Justice stated that ICCPR protection does not cease during armed conflict except through a valid derogation. It added that whether a wartime deprivation of life was arbitrary had to be determined by reference to the law applicable in armed conflict as the relevant lex specialis (ICJ, 1996, para. 25).


The Wall advisory opinion expressed the relationship in broader terms. The Court distinguished matters governed by humanitarian law, matters governed by human rights law, and matters governed by both. It considered both bodies of law when assessing conduct in occupied territory (ICJ, 2004, para. 106). In Armed Activities on the Territory of the Congo, it again applied human rights and humanitarian obligations to conduct during occupation and armed conflict (ICJ, 2005, paras 216–220).


These decisions do not establish that humanitarian law displaces human rights law whenever hostilities begin. Lex specialis assists in resolving a particular overlap or interpretive question between specific rules. The relevant result depends on the conduct, the human rights provision, the humanitarian rule, and the authority deciding the issue.


The right to life illustrates this interaction. During the conduct of hostilities, humanitarian rules on distinction, proportionality, precautions, military objectives, and persons hors de combat may inform whether a deprivation of life was arbitrary. Operations governed primarily as law enforcement may require a different assessment of necessity and the use of force. The existence of an armed conflict does not make every use of force a conduct-of-hostilities question.


Detention presents another form of overlap. In Hassan v United Kingdom, the European Court interpreted Article 5 of the Convention in light of the detention powers and safeguards contained in the Third and Fourth Geneva Conventions. Although the United Kingdom had not derogated from Article 5, the Court sought to accommodate the Convention and humanitarian law through interpretation and found no violation of the relevant Article 5 guarantees (ECtHR, 2014, paras 102–107). That reasoning belongs to the European Convention system and should not be presented as a universal solution to wartime detention.


Occupation may likewise engage both regimes. Humanitarian law regulates the authority and duties of an occupying power. Applicable human rights treaties continue to protect persons who fall within that state’s jurisdiction. Some questions may be governed primarily by specific rules of occupation, while others—including discrimination, education, family life, expression, or access to remedies—may remain principally within human rights law or require consideration of both regimes.


The existence of armed conflict is not itself a derogation. A state seeking to depart from a derogable human rights obligation must still invoke the relevant treaty clause and satisfy its conditions. Nor does reference to humanitarian law establish, without further analysis, that a non-derogable human rights obligation has been respected.


The relationship must therefore be examined issue by issue. The analysis should identify the classification of the armed conflict, the state’s jurisdiction, the human rights provision, the applicable humanitarian rule, any valid derogation, and the authority supporting the proposed relationship between them. A general reference to lex specialis cannot replace that inquiry.


7. Domestic Remedies and International Supervision


Most human rights obligations are implemented through domestic institutions. Constitutions, legislation, public administration, courts, police, armed forces, regulators, and public services determine whether international guarantees operate in practice. International procedures supplement these systems; they do not form a single global appellate structure capable of replacing them.


Access to an international review normally follows several prior questions. The relevant obligation must bind the state, domestic law must provide or recognize a route for implementation, and the claimant must satisfy the jurisdictional and procedural requirements of the international mechanism concerned. A finding of violation is distinct from the remedy ordered and from the state’s eventual compliance.


7.1 Domestic Implementation and Effective Remedies


International law does not prescribe one constitutional method for receiving human rights treaties. In some states, ratified treaties may be applied directly by courts. Elsewhere, implementing legislation is required before treaty provisions can be invoked domestically. A treaty may possess constitutional, supra-legislative, statutory, or interpretive status, and its direct effect may differ provision by provision.


The categories of monism and dualism describe broad tendencies but often obscure mixed domestic arrangements. An unincorporated treaty may influence statutory interpretation or administrative discretion. An incorporated provision may still be considered too general for direct judicial application. Constitutional rights may also provide protection broader than the corresponding international obligation.


These domestic differences do not alter the state’s responsibility internationally. A party may not rely on its internal law to justify failure to perform a treaty in force for it (Vienna Convention on the Law of Treaties, 1969, art. 27).


Implementation extends beyond courts. Legislatures may need to repeal incompatible laws, establish safeguards, create causes of action, or regulate private conduct. Executive agencies administer detention, migration, education, health, social security, and other areas in which rights are realized or restricted. The police and the armed forces require lawful rules governing arrest, detention, interrogation, surveillance, and the use of force. Administrative bodies must provide fair procedures, reasons, review, and protection against discrimination.


Courts may protect rights through constitutional review, statutory interpretation, judicial review, criminal proceedings, and civil remedies. Their powers vary: some may invalidate legislation, while others issue declarations, award damages, or interpret statutes consistently with rights where possible. Standing may be limited to directly affected persons or extended to representatives, public-interest applicants, or national human rights institutions.


National human rights institutions may investigate complaints, monitor public bodies, advise governments, submit reports, and promote legal reform. Their value depends on their independence, mandate, resources, pluralism, and access to information. The Paris Principles provide non-binding international standards for those institutional characteristics (United Nations General Assembly, 1993).


Article 2(3) of the ICCPR requires states parties to provide an effective remedy, ensure that claims are determined by competent authorities, and enforce remedies when granted (ICCPR, 1966, art. 2(3)). A remedy is not effective merely because it exists formally. It must be accessible and capable of addressing the alleged violation.


The appropriate response depends on the right, injury, and forum. It may include cessation, investigation, release, restitution, compensation, rehabilitation, satisfaction, or measures intended to prevent repetition. International responsibility recognizes restitution, compensation, and satisfaction as forms of reparation, while UN remedial principles also refer to rehabilitation and guarantees of non-repetition (ILC, 2001, arts 30–37; United Nations General Assembly, 2005, principles 18–23). No institution possesses every remedial power in every case.


7.2 UN Treaty Bodies and Charter Mechanisms


UN supervision operates through treaty-based and Charter-based procedures. Their legal bases, membership, powers, and outcomes differ.


Most treaty bodies are committees of independent experts established by the treaty they supervise. The Committee on Economic, Social and Cultural Rights is an exception: ECOSOC created it in 1985 to perform the monitoring functions assigned to the Council under the ICESCR (ECOSOC, 1985). Each committee acts only within the authority conferred by its governing instrument.


Periodic reporting is the core supervisory procedure. States submit information on laws, institutions, policies, and practices. The committee examines the report through dialogue with state representatives and adopts concluding observations containing concerns and recommendations. These observations supervise implementation at a systemic level; they are not judgments resolving individual claims.


Individual communications provide a case-specific procedure where the relevant treaty, optional protocol, or declaration grants competence and the respondent state has accepted it. Ratification of a substantive treaty does not necessarily include acceptance of individual complaints. The committee considers jurisdiction and admissibility before reaching the merits.


A finding is commonly expressed through Views or another treaty-specific form of decision. Treaty-body Views are reasoned determinations by the expert institution entrusted with supervising the treaty, but they do not possess the same formal status or enforcement structure as judgments of an international court. Committees may request follow-up information and recommend measures such as compensation, release, investigation, reconsideration, or legal reform.


Some treaty regimes also provide for interstate communications or inquiries into grave or systematic violations. Their availability may be automatic under the treaty, depend on reciprocal declarations, or permit a state to exclude the procedure. Committees considering individual communications may request interim measures to prevent irreparable harm. Such requests do not decide admissibility or the merits.


Charter-based mechanisms derive authority from the UN Charter and resolutions of competent UN organs rather than from one human rights treaty. The Human Rights Council conducts the Universal Periodic Review, appoints special procedures, and may establish commissions of inquiry or fact-finding missions (United Nations General Assembly, 2006).


The Universal Periodic Review examines every UN member state through an intergovernmental process. Other states make recommendations, which the reviewed government may support or note. The process does not issue binding judgments or award remedies to individuals.


Special rapporteurs, independent experts, and working groups examine thematic questions or country situations. They may conduct visits, send communications, prepare reports, and make recommendations. Commissions of inquiry and fact-finding missions investigate particular situations, establish facts, identify applicable law, or preserve evidence. These mechanisms may exercise considerable evidentiary and political influence, but they do not conduct criminal trials or issue binding human rights judgments.


7.3 Regional Courts and Commissions


Regional systems differ in their access rules, institutions, jurisdiction, and remedial authority. The European system permits direct individual application to a permanent court. The Inter-American system generally requires prior proceedings before a commission. The African system combines a commission and a court, with direct access to the Court, subject to additional state consent.


Under Article 34 of the European Convention, individuals, nongovernmental organizations, and groups claiming to be victims may apply directly to the European Court of Human Rights. Article 35 governs admissibility, and Article 41 permits just satisfaction where appropriate. Final judgments bind the respondent state in the case concerned, while the Committee of Ministers supervises execution under Article 46 (European Convention on Human Rights, 1950, arts 34–35, 41 and 46).


The European Court may indicate interim measures under Rule 39 of its Rules of Court where an imminent risk of irreparable harm exists. Interim measures preserve the proceedings; they do not determine whether a violation has occurred.


In the Inter-American system, petitions are first examined by the Inter-American Commission. The Commission considers admissibility and merits, may facilitate friendly settlement, and issues findings and recommendations. Its reports do not have the same formal legal status as judgments of the Inter-American Court.


Only the Commission and states parties may submit contentious cases to the Inter-American Court. The respondent must be party to the American Convention and have accepted the Court’s jurisdiction under Article 62 (American Convention on Human Rights, 1969, arts 61–62). The Court may order restitution, compensation, investigation, legislative change, rehabilitation, public acknowledgment, and other reparative measures under Article 63. Its judgments bind the parties to the case, and the Court supervises compliance (arts 63 and 68).


Article 63(2) authorizes provisional measures in cases of extreme gravity and urgency where necessary to prevent irreparable harm. They do not prejudge the merits.


The African Commission examines state reports, interprets the African Charter, and considers communications alleging violations. Its findings and recommendations exercise supervisory authority but are not formally equivalent to judgments of the African Court.


The African Court was created by a separate protocol. Cases may be submitted by the Commission, states, and specified African intergovernmental organizations. Individuals and nongovernmental organizations may apply directly only against a state that has made the declaration required by Article 34(6); an NGO must also satisfy the applicable observer-status requirement (African Court Protocol, 1998, arts 5 and 34(6)).


The Court may order appropriate reparation and provisional measures to prevent irreparable harm. States undertake to comply with judgments in cases to which they are parties. Judgments are transmitted to the parties and the relevant African Union organs, while non-compliance may be reported through the Court’s annual reporting process (African Court Protocol, 1998, arts 27 and 29–31).


Regional arrangements outside these systems provide different and generally more limited forms of review. Their authority must be determined from their own constitutive instruments rather than inferred from the existence of a regional declaration or committee.


7.4 Access, Authority, and Compliance


Jurisdiction, admissibility, merits, remedy, and implementation are separate stages. A serious allegation may fail procedurally without being examined on its substance, while an admissible claim may later fail on the merits.


Jurisdiction concerns the institution’s legal competence over the state, treaty, person, territory, and relevant period. The state must be bound by the applicable instrument and, where required, must have accepted the particular complaints procedure or court jurisdiction.


Standing determines who may initiate proceedings. Under the European Convention, an applicant must claim to be a victim. Other systems permit petitions by representatives, organizations, or persons acting on behalf of alleged victims. The African Commission has also accepted communications without requiring the author to be personally affected. Standing rules must therefore be identified within the relevant procedure.


Exhaustion of domestic remedies ordinarily gives national authorities the first opportunity to correct the alleged violation. Applicants need to pursue only remedies that are available, effective, and capable of providing relevant relief. Procedures that are unavailable in practice, unduly prolonged, or incapable of addressing the claim may fall within treaty-specific exceptions.


International mechanisms also impose time limits or reasonable time requirements. They may prohibit anonymous or insufficiently substantiated claims and may restrict examination of matters already considered, or being considered, through another international procedure. The wording and effect of duplication rules differ among instruments.


An admissibility ruling does not establish a violation. It determines whether the institution may examine the merits. A merits finding must then be distinguished from the remedy, which depends on the body’s powers and the circumstances of the case.


The authority of the outcome also varies. A regional court may issue a binding judgment. A commission may adopt findings and recommendations. A treaty body may issue Views under an accepted communications procedure. The Universal Periodic Review and special procedures produce political or expert recommendations rather than adjudicative decisions.


Compliance forms a final and separate stage. Even a binding judgment may require legislation, payment, release, investigation, reopening of proceedings, or cooperation among several branches of government. Treaty bodies, courts, commissions, and political organs use different follow-up and monitoring procedures, but implementation ultimately depends heavily on domestic institutions.


International supervision is therefore neither legally uniform nor practically self-executing. Its significance depends on the institution’s mandate, the procedure used, the parties bound, the remedy available, and the system through which compliance is monitored.

8. Compliance, Unequal Power, and Institutional Limits


International human rights law depends on institutions that it does not centrally control. Treaties establish obligations, and international bodies may interpret those obligations or find violations, but implementation usually requires action by domestic legislatures, courts, ministries, prosecutors, police services, regulators, and public authorities. Where those institutions lack independence, resources, competence, or political support, an international decision may remain only partially implemented.


International supervision has similar dependencies. Treaty bodies rely on states to report, provide information, participate in review, and respond to findings. Courts depend on cooperation during proceedings and on national authorities to execute judgments. Special procedures and investigative mechanisms may be denied access to territory, official records, detention facilities, or witnesses. Civil society can supply information absent from state reports, but its participation may be restricted through funding controls, registration requirements, surveillance, or intimidation.


Funding and administrative capacity affect both institutions and applicants. International mechanisms require staff, translation, secure evidence systems, investigation, and adequate meeting time. Applicants may need legal representation, expert evidence, translation, and years of domestic litigation before an international complaint becomes possible. OHCHR has identified growing backlogs, insufficient state reporting, and resource limitations among the continuing weaknesses of the UN treaty-body system (OHCHR, n.d.).


These constraints are not distributed evenly. States participate in different treaties, optional protocols, jurisdictional declarations, and regional systems. A person in one country may have direct access to a court capable of issuing a binding judgment. Another person alleging comparable harm may have access only to reporting, political review, or non-binding recommendations. This variation follows from the system’s legal architecture rather than from a difference in the inherent value of the rights involved.


Political power also affects the practical consequences of non-compliance. Human rights institutions generally lack their own police, enforcement agencies, or independent sources of revenue. They depend on treaty consent, domestic execution, diplomatic engagement, and institutional follow-up. States with greater geopolitical or economic leverage may be better able to resist criticism, delay implementation, or absorb reputational costs. Less influential states may face different forms of pressure. These disparities do not alter the applicable legal rule, but they affect the likelihood and cost of enforcement.


Selectivity can arise without invalidating the legal findings that are made. A court cannot hear a claim against a state outside its jurisdiction. A treaty body cannot supervise obligations outside its constitutive instrument. A commission of inquiry may examine one situation because a political organ created a mandate, while similar conduct elsewhere receives no equivalent investigation. The legal accuracy of a particular decision must therefore be distinguished from broader questions about why some situations receive sustained institutional attention, and others do not.


Domestic politics create another source of unevenness. Compliance may require agreement among courts, legislatures, ministries, prosecutors, regional authorities, and security institutions. A government may pay compensation while refusing structural reform, amend legislation without changing administrative practice, or accept recommendations while denying the underlying legal interpretation. Formal compliance can therefore coexist with continued violations.


Digital surveillance shows how established rights must operate where state and private power are intertwined. Contemporary surveillance may involve intelligence agencies, foreign partners, telecommunications providers, platform operators, data brokers, and companies that design interception or spyware systems. Relevant questions include privacy, expression, journalistic confidentiality, territorial jurisdiction, state attribution, corporate regulation, access to evidence, and independent oversight.


In Big Brother Watch and Others v United Kingdom, the Grand Chamber did not hold that bulk interception was inherently incompatible with the European Convention. It found that the former UK bulk-interception regime violated Article 8 because it lacked sufficient safeguards at important stages of the process. The regime for acquiring communications data also violated Article 8. Deficiencies in the protection of confidential journalistic material produced corresponding violations of Article 10. The separate system for receiving intelligence from foreign governments was not found to violate the Convention (Big Brother Watch and Others v United Kingdom, 2021).


The judgment demonstrates both the reach and the limits of judicial supervision. The Court examined the respondent state’s legal framework and the safeguards governing its authorities. It did not regulate every company supplying surveillance technology, determine the responsibility of foreign intelligence partners, or create a universal surveillance code. Those questions may depend on domestic regulation, export controls, procurement rules, other treaty systems, and the legal relationship between the state and the private actor.


Commercial spyware makes those divisions particularly difficult. A company may develop the technology in one state, sell it through intermediaries, and enable its use by authorities elsewhere. The company’s conduct is not automatically attributable to the purchasing state or to the state where it is incorporated. State responsibility may instead arise from direct governmental use, participation in deployment, failure to regulate foreseeable abuse, or failure to investigate an unlawful intrusion. Corporate responsibilities under the UN Guiding Principles remain non-binding at the international level, while binding duties increasingly depend on national and regional law.


Climate change presents a different problem of dispersed responsibility. Greenhouse-gas emissions arise from public and private activity across many jurisdictions, accumulate over time, and cause harm far from their source. Applying human rights law requires decisions about positive obligations, victim status, causation, regulatory discretion, territorial reach, and the contribution expected from an individual state.


In Verein KlimaSeniorinnen Schweiz and Others v Switzerland, the European Court held that Article 8 encompasses protection against serious adverse effects of climate change on life, health, well-being, and quality of life. It found that Switzerland had failed to comply with its positive obligations because of critical gaps in its regulatory framework and its failure to act in good time and consistently toward its emissions-reduction objectives. The applicant association had standing, but the four individual applicants did not satisfy the demanding victim-status criteria. The Court also found a violation of Article 6(1) concerning the association’s access to a court (Verein KlimaSeniorinnen Schweiz and Others v Switzerland, 2024).


That judgment is significant, but its reach must be stated accurately. It interprets the European Convention and binds Switzerland in the case concerned. It does not establish that every inadequate climate policy violates international human rights law, that every person affected by climate change has individual standing, or that all regional and UN institutions must adopt the same test. Questions of causation, jurisdiction, victim status, and the division of regulatory responsibility remain contested across legal systems.


Digital surveillance and climate harm expose a recurring institutional difficulty. The state remains the principal treaty duty-bearer, yet the power affecting protected rights may be distributed among governments, international partners, corporations, contractors, platforms, and infrastructure providers. Existing rights remain relevant, but legal responsibility must still be connected to a particular state obligation, act or omission, jurisdictional basis, and competent procedure.


The system’s weakness lies less in the absence of recognized rights than in the unequal capacity to invoke, apply, and enforce them. International mechanisms can clarify legal duties, preserve evidence, expose violations, support domestic litigation, and impose political or reputational costs. Their effectiveness remains constrained by jurisdiction, funding, institutional access, national implementation, and the political power of the actors whose conduct is under review.


Conclusion


International Human Rights Law is neither a single moral declaration nor a centralized global constitutional system. It is a decentralized body of treaty obligations, customary rules, domestic laws, judicial decisions, and supervisory procedures whose legal force depends on their source, scope, and institutional basis. Universal language does not eliminate differences in treaty participation, reservations, jurisdiction, access to procedures, or remedial authority.


A legally defensible human rights claim requires more than identifying a recognized right. It must establish why the relevant rule binds the state, whether the person or situation falls within its jurisdiction, whether the conduct is attributable to the state or engages a positive obligation, and whether the applicable duty has been breached. Any limitation or derogation must satisfy the conditions of the governing instrument, and any remedy must fall within the competence of the institution considering the claim.


Recognition of a right does not necessarily make it directly enforceable in domestic courts. Domestic enforceability does not guarantee access to an international mechanism. Access to review does not determine the merits, and a favorable decision does not ensure implementation. These distinctions are essential to understanding both the legal strength and the institutional limits of the system.


International Human Rights Law nevertheless provides a legal framework through which state power can be constrained, private harm can generate duties of protection, violations can be examined, and remedies can be pursued. Its effectiveness depends on the interaction of binding rules, domestic institutions, international supervision, and sustained compliance. Understanding that structure is more accurate than treating the field either as an unenforceable moral aspiration or as a uniform system of global adjudication.
