A peremptory norm (also called jus cogens or ius cogens, /ˌdʒʌs ˈkoʊdʒɛnz/ or /ˌjʌs/; Latin for "compelling law") is a fundamental principle of international law which is accepted by the international community of states as a norm from which no derogation is ever permitted.
There is no clear agreement regarding precisely which norms are jus cogens nor how a norm reaches that status, but it is generally accepted that jus cogens includes the prohibition of genocide, maritime piracy, slaving in general (to include slavery as well as the slave trade), torture, and wars of aggression and territorial aggrandizement.

Famous quotes containing the word norm:
“A society that presumes a norm of violence and celebrates aggression, whether in the subway, on the football field, or in the conduct of its business, cannot help making celebrities of the people who would destroy it.”
—Lewis H. Lapham (b. 1935)
