This essay analyzes the work of the International Law Commission during its sixty-fourth session in Geneva from May 7 to June 1, and from July 2 to August 3, 2012. The session marked the first year of a new quinquennium (2012-2016), with the Commission having completed its work during the prior quinquennium on four major topics: transboundary aquifers; reservations to treaties; responsibility of international organizations; and effects of armed conflict on treaties. The central topic under discussion during the sixty-fourth session concerned the expulsion of aliens, which led to the adoption on first reading of thirty-two articles, together with commentaries, regarding a State’s power to remove non-nationals coercively from its territory. Work proceeded on the other topics already on the ILC’s agenda and two new topics were added to that agenda: the provisional application of treaties and customary international law
