• Terrorists are, however, excluded from refugee protection. Refugee status cannot be claimed by any person where there are serious reasons for considering they have committed: o crimes against peace, a war crime or a crime against humanity; o serious non-political crimes; or o acts contrary to the purposes and principles of the United Nations. • Where a person has grounds for claiming refugee status, but where there are also reasons for suspecting them as a terrorist, they should have access to fair status determination procedures to assess their claim to refugee status and whether they are excluded from refugee protection. • Non-refoulement is a customary rule of international law binding on all States. This means that refugees should not be returned to a territory where their life or freedom would be threatened on account of their race, religion, nationality, membership of a particular social group or political opinion. • An exception is permitted where there are reasonable grounds for regarding a person as a danger to the country in which they are seeking asylum, or where they, having been convicted of a particularly serious crime, constitute a danger to the community of that country. In such cases there should also be a fair procedure to determine whether a person comes within such exception. • Even if a person is not entitled to protection as a refugee, they cannot be returned to a situation where they are likely to face torture or a risk to their life or other fundamental human rights. 19
