State Responsibility
When states break international law — what counts as a wrongful act, what remedies exist, and the limits of accountability.
Internationally Wrongful Acts
The law of state responsibility governs what happens when a state breaches an international obligation. The International Law Commission's Articles on State Responsibility (2001) — while not a treaty — are widely considered to reflect customary international law.
A state commits an internationally wrongful act when:
- Conduct is attributable to the state (actions of government officials, military, or agents acting under state direction).
- That conduct constitutes a breach of an international obligation.
The consequences include:
- Cessation: The state must stop the wrongful conduct.
- Reparation: The injured state is entitled to full reparation — through restitution (restoring the original situation), compensation (financial payment), or satisfaction (an apology or acknowledgment).
States may also take countermeasures — proportionate, non-forcible measures to induce compliance (like economic sanctions).
