Treaties conflicting with a peremptory norm of
general international law (“jus cogens”)
A treaty is void if, at the time of its conclusion, it conflicts with a peremptory norm of general
international law. For the purposes of the present Convention, a peremptory norm of general
international law is a norm accepted and recognized by the international community of States as a whole
as a norm from which no derogation is permitted and which can be modified only by a subsequent norm
of general international law having the same character.
