Crimes that affect the proper functioning of international society. Some authorities regard so-called international crimes as crimes of individuals that all or most states are bound by treaty to punish in accordance with national laws passed for that purpose. Examples of this type of crime are piracy, hijacking, and war crimes. The International Law Commission has formulated Draft Articles on State Responsibility, which attempt to define international crimes for which individual states are liable. It gives as examples: (1) a serious breach of an international obligation essential to safeguard international peace (e.g. aggression) or peoples' rights to self-determination (e.g. colonial domination by force); (2) a widespread and serious breach of obligations essential to safeguard individuals (e.g. slavery, genocide, or apartheid) or the environment (e.g. massive pollution).
