The International Criminal Court (ICC) in The Hague is a treaty-based, international criminal court established to prosecute genocide, crimes against humanity and war crimes. Although the crime of aggression is also listed, the Court’s jurisdiction in this regard is subject to a number of procedures which were agreed at the Review Conference of the Rome Statute of the International Criminal Court, convened in Kampala, Uganda from 31 May to 11 June 2011.
The Court is an independent international organisation with a special relationship with the United Nations. It is complementary to national jurisdictions in that it may only proceed with a case where a state is unable or unwilling to investigate or prosecute. The Statute of the Court, known as the Rome Statute, was adopted on 17 July 1998 and entered into force on 1 July 2002.
Because submission to the jurisdiction of the International Criminal Court entails a partial transfer to the Court of the sovereign power of the State to administer criminal justice, it was necessary to amend the Irish Constitution prior to ratification. To this end, the twenty-third amendment of the Constitution inserted Article 29.9, providing that the State may ratify the Rome Statute. Ireland has ratified the Statute and accordingly is a member of the Assembly of State Parties. In addition, an Irish lawyer, Judge Maureen Harding Clark, served as a judge of the Court in the Court's Trial Division from 2003 until 2006.
Rome Statute deals with the establishment of the Court, its jurisdiction and the general principles of criminal law to be applied. It sets out the composition of the Court and its administration, the procedures for investigation, prosecution and trial, the penalties which can be imposed on conviction, and provides for appeals.
The procedures under the Statute guarantee respect for the rights of the accused and will ensure that due process be observed. There is an obligation on the States Parties to cooperate with the Court, and provision is also made for the enforcement of the judgments of the Court and for the carrying out of sentences. The Statute, furthermore, provides for an Assembly of States Parties, as a “management oversight and legislative body”, and for the financing of the Court.
A Review Conference of the Rome Statute of the International Criminal Court was convened in Kampala, Uganda from 31 May to 11 June 2011. At that Conference it was agreed to amend the Statute in order to extend the definition of war crimes falling within the jurisdiction of the Court and in order to include provisions relating to the definition of the crime of aggression and in relation to the Court’s jurisdiction in respect of this crime.
Read the full text of the Rome Statute incorporating the amendments agreed at the Review Conference in Kampala.
Article 5 of the Rome Statute sets out that “the most serious crimes of concern to the international community” namely, the crime of genocide, crimes against humanity, war crimes and the crime of aggression are within the jurisdiction of the Court. The Court Statute provided that the Court could exercise jurisdiction over genocide, crimes against humanity and war crimes committed after the date on which the Statute enters into force.
At the time of the adoption of the Rome Statute in 1998, it was not possible to provide for the Court to exercise jurisdiction over the crime of aggression as no agreement had been reached on a provision defining the crime and setting out the conditions under which the Court could exercise jurisdiction with respect to this crime. However, the Rome Statute was amended at the Review Conference of the Rome Statute of the International Criminal Court, convened in Kampala, Uganda from 31 May to 11 June 2011. At is 13th meeting, on 11 June 2010, the Conference adopted resolution RC/Res.6 by which it amended the Rome Statute so as to include a definition of the crime of aggression and the conditions under which the Court could exercise jurisdiction with respect to the crime. The actual exercise of jurisdiction is subject to a decision to be taken after 1 January 2017 by the same majority of States Parties as is required for the adoption of an amendment to the Statute, and one year, after the ratification or acceptance of the amendments by 30 States parties, whichever is the later.
The definitions of genocide, crimes against humanity and war crimes contained in the Statute codify existing international law.
The definition of the crime of aggression is based on United Nations General Assembly resolution 3314 (XXIX) of 14 December 1974, and in this context includes a crime committed by a political or military leader which by its character, gravity and scale constitute a manifest violation of the Charter of the United Nations.
