State Responsibility in International Law

Introduction – State Responsibility

State Responsibility is a fundamental principle of Public International Law, outlining when and how a state is legally accountable for its actions that violate international law. It establishes the legal consequences for wrongful acts by states, including injury to another state or its nationals, breach of treaty obligations, and violations of customary international law.

The doctrine balances sovereign freedom with accountability, ensuring that states cannot act with impunity and that injured states or parties have recourse. It is codified primarily in the Articles on Responsibility of States for Internationally Wrongful Acts (2001) by the International Law Commission (ILC).

1. Meaning and Definition

• Oppenheim defines state responsibility as:
  “The liability of a state for internationally wrongful acts and the obligation to make reparation.”
• ILC Articles (2001):
  “Every internationally wrongful act of a state entails the international responsibility of that state.”

Key Elements:

1. Action attributable to the state – conduct of state organs, officials, or persons acting under state authority.
2. Breach of international obligation – violation of a treaty, customary law, or general principles of law.
3. Resulting injury – harm caused to another state, entity, or individual.

2. Sources of State Responsibility

1. Treaty Violations
   • Breach of a treaty obligation triggers responsibility and reparations.
   • Example: Corfu Channel Case (UK v. Albania, 1949) – Albania responsible for mine damage in its territorial waters.
2. Customary International Law Violations
   • Acts contrary to principles of international law also engage responsibility.
   • Example: Iraq’s invasion of Kuwait (1990) – violation of territorial integrity.
3. UN Charter Violations
   • Acts contrary to prohibition of use of force (Article 2(4)) and obligations under UN resolutions.
