In this, the inaugural Manfred Lachs Memorial Lecture given at the seat of the International Court of Justice, we celebrate the judicial life and learning, and also the judicial wisdom of the longest-serving judge of the Court and its sometime President, who died on January 14th, 1993. Manfred Lachs came to the Court in February, 1967, having been elected in October, 1966, in the first elections following the Court's politically and, in some elements at least (judicial recusation, as example)legally controversial decision in South West Africa, Second Phase1 which had been rendered only two months before the UN Security Council and General Assembly regular triennial balloting on renewal or replacement of one third of the Court's membership.
