Organs
The ICC has four principal organs: the Presidency, the Judicial Divisions, the Office of the Prosecutor and the Registry.
The President is the most senior judge chosen by the eighteen judges in the Judicial Division.
The Judicial Division is composed of eighteen judges and hears cases before the Court.
The Office of the Prosecutor is headed by the Prosecutor, who investigates crimes and initiates criminal proceedings before the Judicial Division.
The Registry is headed by the Registrar and is charged with managing all the administrative functions of the ICC, including the headquarters, detention unit, and public defence office.
The ICC employs over 900 personnel from roughly 100 countries and conducts proceedings in English and French.
The Presidency is responsible for the proper administration of the Court (apart from the Office of the Prosecutor). It comprises the President and the First and Second Vice-Presidents—three judges of the Court who are elected to the Presidency by their fellow judges for a maximum of two three-year terms.
Song Sang-hyun was the President of the ICC from 2009 to 2015. As of March 2024, the President is Tomoko Akane from Japan, who took office on 11 March 2024, succeeding Piotr Hofmański. Her first term will expire in 2027.
The Judicial Divisions consist of the 18 judges of the Court, organised into three chambers—the Pre-Trial Chamber, Trial Chamber and Appeals Chamber—which carry out the judicial functions of the Court. Judges are elected to the Court by the Assembly of States Parties. They serve nine-year terms and are not generally eligible for re-election. All judges must be nationals of states parties to the Rome Statute, and no two judges may be nationals of the same state. They must be "persons of high moral character, impartiality and integrity who possess the qualifications required in their respective States for appointment to the highest judicial offices".
The Prosecutor or any person being investigated or prosecuted may request the disqualification of a judge from "any case in which his or her impartiality might reasonably be doubted on any ground". Any request for the disqualification of a judge from a particular case is decided by an absolute majority of the other judges. Judges may be removed from office if "found to have committed serious misconduct or a serious breach of his or her duties" or is unable to exercise his or her functions. The removal of a judge requires both a two-thirds majority of the other judges and a two-thirds majority of the states parties.
The Office of the Prosecutor (OTP) is responsible for conducting investigations and prosecutions. It is headed by the Prosecutor of the International Criminal Court, who is assisted by one or more Deputy Prosecutors. The Rome Statute provides that the Office of the Prosecutor shall act independently; as such, no member of the Office may seek or act on instructions from any external source, such as states, international organisations, non-governmental organisations or individuals.
The Prosecutor may open an investigation under three circumstances:
when a situation is referred by a state party;
when a situation is referred by the United Nations Security Council, acting to address a threat to international peace and security; or
when the Pre-Trial Chamber authorises the prosecutor to open an investigation on the basis of information received from other sources, such as individuals or non-governmental organisations.
Any person being investigated or prosecuted may request the disqualification of a prosecutor from any case "in which their impartiality might reasonably be doubted on any ground". Requests for the disqualification of prosecutors are decided by the Appeals Chamber. A prosecutor may be removed from office by an absolute majority of the states parties through a finding "to have committed serious misconduct or a serious breach of his or her duties" or is unable to exercise his or her functions.
Lead prosecutor Luis Moreno Ocampo of Argentina, in office from 2003 to 2012, was succeeded in the role by Fatou Bensouda of Gambia, who served from 16 June 2012 to 16 June 2021. (She was elected to the nine-year term on 12 December 2011.)
On 12 February 2021, British barrister Karim Khan was selected in a secret ballot against three other candidates to serve as lead prosecutor as of 16 June 2021. As a British barrister, Khan had headed the United Nations' special investigative team when it looked into Islamic State crimes in Iraq. At the ICC, he had been lead defence counsel on cases from Kenya, Sudan and Libya.
The Office of the Prosecutor occasionally publishes policy papers that put forth the considerations given to topics the office focuses on, and often the criteria for case selection. While a policy paper does not give the Court jurisdiction over a new category of crimes, it promises what the Office of Prosecutor will consider when selecting cases in the upcoming term of service. OTP's policy papers are subject to revision.
The following papers have been published since the start of the ICC:
1 September 2007: Policy Paper on the Interest of Justice
12 April 2010: Policy Paper on Victims' Participation
1 November 2013: Policy Paper on Preliminary Examinations
20 June 2014: Policy Paper on Sexual and Gender-Based Crimes
15 September 2016: Policy paper on case selection and prioritisation
15 November 2016: Policy on Children
The paper published in September 2016 announced that the ICC will focus on environmental crimes when selecting cases. The Office will give particular consideration to prosecuting Rome Statute crimes that are committed by means of, or that result in, "inter alia, the destruction of the environment, the illegal exploitation of natural resources or the illegal dispossession of land". This has been interpreted as a major shift in environmental law and a move with significant effects.
The Registry is responsible for the non-judicial aspects of the administration and servicing of the Court. This includes, among other things,
The administration of legal aid matters, court management, victims and witnesses matters, defence counsel, detention unit, and the traditional services provided by administrations in international organisations, such as finance, translation, building management, procurement and personnel.
The Registry is headed by the Registrar, who is elected by the judges to a five-year term. As of April 2023 the Registrar is Osvaldo Zavala Giler.
