Arrest Warrant (ICJ)

Summary:

The Democratic Republic of the Congo (DRC) brought proceedings against Belgium concerning an international arrest warrant issued against the DRC’s sitting Minister for Foreign Affairs, Mr. Abdulaye Yerodia Ndombasi. On 11 April 2000, Belgium issued an international arrest warrant in absentia charging Mr. Yerodia with grave breaches of the 1949 Geneva Conventions and crimes against humanity; the allegations also referenced AP I and AP II. Under Belgian law, Belgian courts claimed jurisdiction “wheresoever” the offenses occurred and stated that immunity does not prevent application of the law. At the time of issuance and circulation, Mr. Yerodia was not a Belgian national, was not present in Belgian territory, and no Belgian nationals were victims.

International law recognizes that diplomatic and consular agents and high-ranking State representatives—including the Head of State, Head of Government, and Minister for Foreign Affairs—enjoy immunities from civil and criminal jurisdiction in other States. The Vienna Convention on Diplomatic Relations (VCDR) and the Vienna Convention on Consular Relations (VCCR) generally reflect customary international law. Immunities accorded to foreign ministers exist to ensure the effective performance of State functions, not for personal benefit. A foreign minister is presumed to have full powers by virtue of office and must be able to travel freely and maintain constant communication with the home government, diplomatic missions, and representatives of other States. Consequently, a foreign minister enjoys full immunity from criminal jurisdiction and inviolability abroad for the duration of office, and arrest on criminal charges would prevent performance of official functions.

Belgium contended that incumbent foreign ministers suspected of war crimes or crimes against humanity cannot claim immunity. The ICJ found no exception in customary international law to the immunity and inviolability of incumbent foreign ministers on that basis and did not accept Belgium’s position. The extension of criminal jurisdiction—for example, for serious crimes—does not affect immunities recognized by customary international law; jurisdiction does not imply absence of immunity, and absence of immunity does not imply jurisdiction. Immunity from jurisdiction does not equal impunity; criminal responsibility and jurisdictional immunity are distinct concepts.

Prosecution of an incumbent or former foreign minister can occur: (1) in their own country; (2) if their State waives immunity; (3) after leaving office, by a State with jurisdiction, for acts before or after tenure and for acts during tenure in a private capacity; and (4) before competent international criminal courts. Arrest of an incumbent foreign minister would impede performance of official functions. Domestic assertions of broad criminal jurisdiction, including for grave international crimes, do not override customary immunities of incumbents. The framework preserves functional immunity and inviolability during tenure while identifying four avenues that maintain accountability.

Exam relevance:

In the Arrest Warrant case (Democratic Republic of the Congo v. Belgium, ICJ 2002), the Court distinguished between personal immunity (ratione personae) and functional immunity (ratione materiae). It held that although a sitting foreign minister had personal immunity from prosecution by another state, once out of office, they could still enjoy immunity ratione materiae for acts performed in an official capacity.
