The paper addresses the issue of the expulsion of aliens under the International Covenant on Civil and Political Rights. General aspects of the expulsion of aliens, as well as the situation of aliens under the Covenant, are first studied. Then the paper approaches the expulsion of aliens under the Covenant from a double point of view: the substantive limits to the power to expel an alien (which may come, for example, from the rules that protect life, physical integrity or family) and the procedural rules which must be respected.

It also mentions the interpretative criteria of the International Court of Justice
