Abstract

This article addresses the need for clarity as regards the sources of public international law, or at least as much clarity as possible. Questions relating to sources lie at the heart of international law. Of particular concern is the lack of rigour shown by some domestic judges when it comes to determining the rules of customary international law.

64. Kosovo Advisory Opinion, ibid., para. 94:

While the rules on treaty interpretation embodied in Articles 31 and 32 of the Vienna Convention on the Law of Treaties may provide guidance, differences between Security Council resolutions and treaties mean that the interpretation of Security Council resolutions also require[s] that other factors be taken into account. Security Council resolutions are issued by a single, collective body and are drafted through a very different process than that used for the conclusion of a treaty. Security Council resolutions are the product of a voting process as provided for in Article 27 of the Charter, and the final text of such resolutions represents the view of the Security Council as a body. Moreover, Security Council resolutions can be binding on all Member States … irrespective of whether they played any part in their formulation. The interpretation of Security Council resolutions may require the Court to analyse statements by representatives of members of the Security Council made at the time of their adoption, other resolutions of the Security Council on the same issue, as well as the subsequent practice of relevant United Nations organs and of States affected by those given resolutions.
