DRC v. Uganda stands as one of the most practically consequential judgments ever delivered by the International Court of Justice on armed conflict between States.

Nicaragua v United States of America stands as one of the most consequential judgments ever delivered by the International Court of Justice (ICJ). Decided in 1986, the case remains a foundational reference for understanding the prohibition of the use of force, the principle of non-intervention, the relationship between treaty law and customary international law, and the legal limits of indirect or proxy warfare.

Arrest Warrant Case (Democratic Republic of the Congo v Belgium) is one of the few International Court of Justice decisions that still structures day-to-day legal advice on both (i) the criminal reach of national courts and (ii) the operational limits imposed by immunities of senior foreign officials.

The Ireland v. United Kingdom case is the European Court of Human Rights’ most consequential early attempt to draw a legally operational line between “torture” and “inhuman or degrading treatment” under Article 3 of the European Convention on Human Rights (ECHR), while simultaneously adjudicating a security-state’s emergency measures under Article 15 and constructing a durable approach to proof in systemic ill-treatment litigation (European Court of Human Rights, 1978).

The Nuremberg trials mark the decisive moment when international law crossed from condemning state conduct to criminally judging individuals acting in the name of the state. Their importance does not lie in symbolism or moral awakening, but in the concrete legal problems they forced into resolution under extreme political pressure.

answer a prior question of public international law: can the United Nations Security Council, acting under Chapter VII, lawfully create a criminal tribunal with authority to try individuals, compel State cooperation, and apply international humanitarian law (IHL) beyond the narrow confines of inter-State war?

The Fisheries Case is not primarily a story about Norwegian fishing enforcement or a bilateral quarrel over maps. It is a foundational decision on how international law constrains the legal construction of the coast—specifically, when a coastal State may replace the normal low-water mark baseline with straight baselines that enclose large maritime spaces as internal waters and, at the same time, generate the baseline from which the territorial sea is measured.

Barcelona Traction Case stands as one of the most structurally important judgments in the jurisprudence of the International Court of Justice, shaping how public international law understands diplomatic protection, corporate nationality, and the limits of State standing in disputes involving private economic interests.

The US v. Iran Hostage Case marks a rare moment in which a rapidly unfolding geopolitical crisis was deliberately reframed as a legal controversy governed by binding norms of public international law.

The Corfu Channel Case occupies a foundational position in the architecture of modern public international law. Decided in 1949, it was the first contentious case on the merits before the International Court of Justice (ICJ) and, more importantly, the first to articulate clearly and authoritatively how international responsibility may arise in the absence of direct attribution of a wrongful act.
