The Security Council was convinced of the need to enhance the powers of ad litem judges at the ICTY to allow them to adjudicate in other pre-trial proceedings before their appointment to a trial, and, acting under Chapter VII of the United Nations Charter, amended the statute accordingly.[2] The change was proposed by Theodor Meron, the president of the ICTY, who added that the measure would make efficient use of temporary judges' time and incur no extra costs on the United Nations.[3]
