While indications of an asylum-seeker’s alleged involvement in acts of terrorism would make it necessary to examine the applicability of article 1F of the 1951 Convention, international refugee law requires an assessment of the context and circumstances of the individual case in a fair and efficient procedure before a decision is taken. Any summary rejection of asylum-seekers, including at borders or points of entry, may amount to refoulement, which is prohibited by international refugee and human rights law. According to the Universal Declaration of Human Rights, all persons have the right to seek asylum. Thirdly, persons who have been recognized as refugees, as well as asylumseekers who are awaiting a determination of their claims, are bound to conform to the laws and regulations of their host country, as specified in article 2 of the 1951 Convention. If they do not do so, they may be prosecuted to the full extent of the law. In addition, exceptions to the principle of non-refoulement exist under article 33 (2) of the 1951 Convention. Denial of protection from refoulement and return to the country of origin are foreseen if there are reasonable grounds for regarding a refugee as a danger to the security of the country in which he or she is or if, having been convicted of a particularly serious crime, that person constitutes a danger to the community of the host State. Finally, the 1951 Convention provides for the possibility of expulsion to a third country on national security grounds under article 32. Implementation of either of these articles may be carried out only following a decision taken by a competent authority in accordance with due process of law, including the right to be heard and the right of appeal. It is crucial to emphasize, however, that the application of either limitation contained in articles 32 or 33 (2) of the 1951 Convention is subject to the other human rights obligations of the State, specifically article 3 of the Convention against Torture and article 7 of the International Covenant on Civil and Political Rights, whose protection is absolute. If a person has already been granted refugee status under the 1951 Convention, such status may be cancelled if there are grounds for considering that the person should not have been recognized as a refugee in the first place. This is the case where there are indications that, at the time of the initial decision, the applicant did not meet the inclusion criteria of the 1951 Convention, or that an exclusion clause of that Convention should have been applied to him or her.28 This might include evidence that the person committed terrorist acts. Cancellation of refugee status is in keeping with the object and purpose of the 1951 Convention, if it is 17
