Jus cogens refers to a fundamental principle of international law that is accepted by the international community as a norm from which no derogation is permitted. These are known as peremptory norms of international law, which are binding on all states and cannot be violated by treaties or other agreements. Such norms encompass prohibitions on acts like genocide, slavery, and torture.
