Some Notable Developments in the Practice of the UN Secretary-General as Depositary of Multilateral Treaties: Reservations and Declarations

Abstract

This Note will examine developments in the practice of the United Nations secretary-general on reservations and declarations to treaties, particularly since 1994 when the Summary of Practice of the Secretary-General as Depositary of Multilateral Treaties was last updated. This period was marked by some notable developments in the previous practice, especially in connection with human rights treaties.The Vienna Convention on the Law of Treaties of 1969 (Vienna Convention) provides the framework for the functions of the secretary-general in his role as depositary of multilateral treaties. Most aspects of the law relating to reservations and declarations to treaties are also codified in the Vienna Convention.Over five hundred multilateral treaties are deposited with the secretary-general. The complex requirements relating to these treaties and the concerns of the many disparate states that may undertake treaty actions with regard to them have significantly influenced his practice. He is also conscious of the political sensitivities surrounding his decisions and the need to protect his own integrity and impartiality.
