Jus Cogens – What It Is and Why It Matters to Your Business

Jus cogens is a Latin expression meaning “compelling law” – a fundamental and irrevocable rule of public international law that all states must observe, even against their own interests. Commonly referred to as “peremptory norms,” they are regarded as a higher level of law than the usual norms found in treaties and conventions.

These rules of international law protect fundamental human rights and reflect the most universally accepted principles of justice. They include the absolute prohibition of crimes such as genocide, slavery, piracy and the killing of hostages, as well as prohibitions on torture, cruel or inhuman punishments and other internationally recognized rights.

Being obligated to observe jus cogens even against their own interests is a duty that no country or court can ignore. This principle serves to protect individuals and entities from the whims of powerful governments.
