The expulsion of such a refugee shall be only in pursuance of a decision reached in accordance with due process of law. Except where compelling reasons of national security otherwise require, the refugee shall be allowed to submit evidence to clear himself, and to appeal to and be represented for the purpose before competent authority or a person or persons specially designated by the competent authority. 3. The Contracting States shall allow such a refugee a reasonable period within which to seek legal admission into another country. The Contracting States reserve the right to apply during that period such internal measures as they may deem necessary. Article 33 1. No Contracting State shall expel or return ("refouler") a refugee in any manner whatsoever to the frontiers of territories where his life or freedom would be threatened on account of his race, religion, nationality, membership of a particular social group or political opinion. 2. The benefit of the present provision may not, however, be claimed by a refugee whom there are reasonable grounds for regarding as a danger to the security of the country in which he is, or who, having been convicted by a final judgement of a particularly serious crime, constitutes a danger to the community of that country.
