Non-Refoulement

The cornerstone principle of refugee law — the prohibition on returning people to places where they face serious harm.

The Principle

Non-refoulement (from the French refouler, 'to push back') is the principle that no state shall return a person to a territory where they face a real risk of persecution, torture, or other serious harm. Article 33(1) of the Refugee Convention states: 'No Contracting State shall expel or return a refugee to the frontiers of territories where his life or freedom would be threatened.'

Non-refoulement is widely considered a norm of customary international law, meaning it binds all states regardless of whether they have ratified the Refugee Convention. The prohibition against return to torture under the Convention Against Torture (Article 3) is absolute — it admits no exceptions.
