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:
“As long as male behavior is taken to be the norm, there can be no serious questioning of male traits and behavior. A norm is by definition a standard for judging; it is not itself subject to judgment.”
