Non-refoulement is a principle of international law which forbids the rendering of a true victim of persecution to their persecutor. Generally the persecutor in mind is a state actor. It is a principle of both the customary and trucial law of nations.
Non-refoulement is a key facet of refugee law, that concerns the protection of refugees from being returned to places where their lives or freedoms could be threatened. Unlike political asylum, which applies to those who can prove a well-grounded fear of persecution based on membership in a social group or class of persons, non-refoulement refers to the generic repatriation of people, generally refugees into war zones and other disaster areas.
It is debatable whether non-refoulement is a jus cogens (peremptory norm) of international law that forbids the expulsion of a refugee into an area, usually their home-country, where the person might be again subjected to persecution.
The principle of "refoulement" was officially enshrined in the 1951 Convention Relating to the Status of Refugees and is also contained in the 1967 Protocol and Art 3 of the 1984 Torture Convention.
The principle of non-refoulement arises out of an international collective memory of the failure of nations during World War II to provide a safe haven to refugees fleeing certain genocide at the hands of the Nazi regime. Today, the principle of non-refoulement ostensibly protects recognized refugees and asylum seekers from being expelled from countries that are signatories to the 1951 Convention or 1967 Protocol. This, however has not prevented certain signatory countries from skirting the international law principle and repatriating or expelling bona fide refugees into the hands of potential persecutors.
Tanzania's actions during the 1994 genocide in Rwanda have been alleged to have violated the nonrefoulement principle. During the height of the crisis when the refugee flows rose to the level of a "mass exodus," the Tanzanian government closed its borders to a group of more than 50,000 Rwandan refugees who were fleeing genocidal violence. In 1996, before Rwanda had reached an appropriate level of stability, around 500,000 refugees were returned to Rwanda from Zaire.
One of the grey areas of law most hotly debated within signatory circles is the interpretation of Article 33. Interdiction of potential refugee transporting vessels on the high seas has been a common practice by the U.S. government, in particular, raising the question of whether Article 33 requires a refugee to be within a country or simply within the power of a country to trigger the right against refoulement.
