Part of the difficulties encountered by refugees lies in the obvious gap between the existence of a right to asylum and the lack of a corresponding state duty to grant asylum. The 1948 Universal Declaration of Human Rights famously provides that “everyone has the right to seek and enjoy in other countries asylum from persecution” (article 14).2 However, this right to seek asylum has not been included in any legally binding instrument. Most notably, there is no mention of this right in the 1951 Refugee Convention. This suggests that states have been very reluctant to give to this “right” any substantive legal content.3 In any case, international law clearly does not provide for a duty to grant asylum. Again, the 1951 Refugee Convention does not make any mention of such a duty. Attempts to introduce any reference to asylum and admission were vigorously opposed during the negotiations leading to the adoption of the Convention.4 It is generally argued that states have a right, rather than a duty, to grant asylum, which follows from their sovereign right to control admission into their territory.5...
While there is no obligation under international law to grant asylum to refugees, states are still bound by the principle of non-refoulement as defined in article 33 of the 1951 Convention. This principle provides that no refugee shall be returned to any country “where his life or freedom would be threatened on account of his race, religion, nationality, membership of a particular social group or political opinion.” This principle is now generally considered to be part of customary international law.9 It must be noted that the principle is not limited to those formally recognised as refugees.10 In other words, asylum-seekers should not be returned to any country where they would face persecution and they benefit from such a prohibition until they are declared not to be refugees.
There has been an on-going debate over the exact scope of the principle of nonrefoulement. It is clear that the prohibition of refoulement applies to all refugees who are already on the territory. Whether it also applies to refugees who arrive at the border and seek admission into the territory has been the subject of disagreement. As mentioned earlier, international law does not contain any obligation to grant asylum. Nevertheless, states should not be free to reject refugees at the frontier and it has been argued that rejection at the frontier does amount to refoulement.11... Not surprisingly, some states do not agree with this interpretation of the principle of non-refoulement.13 Most (in)famously, the US Supreme Court declared in 1993 that the principle applies only to refugees within state territory.14
It may be argued that rejection at the border does not necessarily result in return to a country where the refugee would fear persecution, and thus does not necessarily lead to refoulement. The difficulty with this argument is that it leads to an examination on a case-by-case basis of whether the rejection at the border of a refugee automatically leads to his return to acountry where he would fear persecution. Where the refugee is situated at the border between his country of origin and a neighbouring country, it appears obvious that rejection at the frontier would amount to refoulement. There are many other situations in which it may not be so obvious that rejection at the border amounts to refoulement.
