[Latin: towards all]
(in international law) Obligations in whose fulfilment all states have a legal interest because their subject matter is of importance to the international community as a whole. It follows from this that the breach of such an obligation is of concern not only to the victimized state but also to all the other members of the international community. Thus, in the event of a breach of these obligations, every state must be considered justified in invoking (probably through judicial channels) the responsibility of the guilty state committing the internationally wrongful act. It has been suggested that an example of an erga omnes obligation is that of a people's right to self-determination.
