After the entry into force ofthe Rome Treaty establish ing the European Economic Community European Law had become a majornew field ofinternational law. The experience gained inthat field no doubt constituted an important asset when he left the Ministry of Economic Affairs in 1963 in order to join the Office of the Legal Adviser in the Netherlands Ministry of Foreign Affairs. This move opened broad new perspectives for involvement in international legal affairs and it is probably not exaggerated to say that for the true interna tionallawyer the Office ofthe Legal Adviser in the MinistryofForeign Affairs is the most attractive office which the Netherlands Government has to offer. Entering the Office as an Assistant Legal Adviser in 1963, Adriaan became Deputy Legal Adviser in 1984 and finally in 1989Legal Adviser. He was the fourth Legal Adviser after the Second World War succeed ing in that position l. P. A. Francois, Willem Riphagen and Godert Maas Geesteranus, who had all servedthe cause ofinternational law with great dedication. The position of the legal adviser in matters of international law is ajob ofgreat responsibility and with many facets. It compels the holder of that position to play different roles."
