In Arrest Warrant of 11 April 2000 (Democratic Republic of the Congo v. Belgium), decided on 14 February 2002, the International Court of Justice held that an incumbent Minister for Foreign Affairs was immune from criminal proceedings before a foreign domestic court, even if the charges involved crimes against humanity. Human rights advocates might well regard this decision as a serious setback. Decided against a widespread euphoria brought forth by, and largely due to a neglect of an important dictum in, the historic holding in Pinochet No. 3 [2000] 1 A.C. 147, the case serves further to clarify a crucial point of State immunity in current international law. The Pinochet case dealt with the immunity of a former, as opposed to a serving, Head of State. While the majority of the Law Lords only mentioned in passing that the immunity enjoyed by a serving Head of State ratione personae was absolute, the International Court of Justice stated, in unambiguous language, that:
… in international law it is firmly established that, as also diplomatic and consular agents, certain holders of high-ranking office in a State, such as the Head of State, Head of Government and Minister for Foreign Affairs, enjoy immunities from jurisdiction in other States, both civil and criminal.
