Forthcoming in the Max Planck Yearbook of United Nations Law (27) accepting any perceived restrictions to their discretion over admission and sojourn of nonnationals. V. Conclusion Established to progressively develop international law and promote its codification, the International Law Commission plays a pivotal role in reducing the indeterminacy and uncertainty inherent in the international legal system. While the Commission has been praised for effectively codifying key areas of international law, its work has also shed light on areas that were not directly under its purview. As this article demonstrates, international migration law seems to be a prime example of that. The protection of migrants, refugees, and stateless persons has come to figure prominently in various of its draft articles, conclusions, and studies. The article also emphasized the challenges faced by the Commission when dealing with the many political sensitivities evoked by any attempts to curb states’ discretion in this domain. With the ongoing studies on sea-level rise in relation to international law, the ILC is once again venturing into the domain of international migration law.144 Although the Commission does not intend to provide an exhaustive analysis of the application of international law to sea-level rise, its work will likely identify, clarify, and articulate existing legal frameworks that can be mobilized to deal with the far-reaching consequences of rising sea levels. The initiative is another attempt to use international institutions to address certain effects of climate change. Yet, it remains to be seen what sort of action will be taken after the Commission’s final report and recommendations, as well as whether they will enjoy the same degree of authority as its other works.
