Rome Statute

Definition and Fundamentals of the Rome Statute

Das Rome Statute (in English: Rome Statute of the International Criminal Court, abbreviated: RöSt / ICC-Statute) is an international treaty, adopted on July 17, 1998 at a United Nations diplomatic conference in Rome. Coming into force on July 1, 2002, it formed the legal basis for establishing the International Criminal Court (ICC) in The Hague. The Rome Statute defines the jurisdiction, structure, tasks, functions, and procedural rules of the ICC and is a central regulation in international criminal law.

Background and Historical Development

The pursuit of an international body to prosecute the most serious crimes such as genocide, crimes against humanity, war crimes, and the crime of aggression goes back a long way. After the Nuremberg and Tokyo Trials, the Rome Statute for the first time established a permanent international criminal court. Negotiations during the diplomatic conference in Rome in 1998 resulted in the adoption of the Statute by the majority of participating states.

Scope and Legal Significance

The Rome Statute is a multilateral treaty and one of the most significant international legal instruments for enforcing international criminal law. Its effect is binding on state parties, yet the Statute also has global influence on states that are not parties to it. The regulations of the Statute are directly relevant for the national legislation of signatory states, as they are obliged to harmonize their domestic law with the requirements of the Statute (implementation).

Membership and Ratification

As of June 2024, 124 states have ratified the Rome Statute and are state parties to the ICC. Numerous countries, including major international actors such as the USA, China, India, and Russia, are either not state parties or have signed but not yet ratified the Statute.

Withdrawal and Reservations

The Rome Statute allows withdrawal by formal declaration, which enters into force after one year (Art. 127 RöSt). Individual states such as Burundi and the Philippines have exercised this option. However, withdrawal does not absolve them of obligations incurred during membership. Furthermore, pursuant to Art. 120 RöSt, no reservations to the Statute are permitted, which emphasizes its uniform application.

Structure and Content of the Rome Statute

The Rome Statute comprises 128 articles, divided into 13 parts. Main regulatory areas include:

Substantive Legal Basis

Criminal Offences

The jurisdiction of the ICC extends to four core crimes (Art. 5 RöSt):

  • Genocide (Art. 6 RöSt): extermination by killing, serious physical or mental harm, creating conditions of life calculated to bring about destruction, preventing births, forceful transfer of children of a national, ethnic, racial, or religious group.
  • Crimes against Humanity (Art. 7 RöSt): Includes, among others, murder, extermination, enslavement, deportation, torture, and rape on a widespread or systematic scale.
  • War Crimes (Art. 8 RöSt): Serious violations of the Geneva Conventions, including willful killing, torture, taking hostages, attacks on civilians.
  • Crime of Aggression (Art. 8bis RöSt): The unlawful use of military force by one state in violation of international law. Since the Kampala Conference of 2010, this crime can also be prosecuted following ratification of specific amendments against individual states.

Individual Criminal Responsibility

The Rome Statute regulates individual criminal responsibility and highlights personal criminal liability and punishment (Art. 25 RöSt). Immunities for incumbent heads of state are restricted (Art. 27 RöSt).

Jurisdiction and Competence

Principles of Jurisdiction

The ICC exercises jurisdiction subsidiarily (Art. 17 RöSt). This means that national prosecution takes precedence if a state is willing and able to prosecute itself (principle of complementarity). A case will only be heard by the ICC if national measures are inadequate or have not been carried out.

Exercise of Jurisdiction

The Court is entitled to intervene when:

  • the alleged crime was committed in the territory of a state party or by its nationals,
  • the United Nations Security Council refers a case,
  • or a state party submits a case for investigation.

Procedural Regulations

The Statute provides for independent procedural law with extensive regulations governing investigation, indictment, and trial. Fundamental principles of a fair criminal trial are comprehensively regulated, such as the rights of the accused (Art. 66 f. RöSt), victim protection (Art. 68 RöSt), and witness protection programs.

Structure and Organs of the International Criminal Court

Institutional Structure

According to Part 4 of the Statute, the organs of the ICC include:

  1. Presidency (administrative management)
  2. Pre-Trial Chamber, Trial Chamber, Appeals Chamber
  3. Office of the Prosecutor
  4. Registry (administrative and support service)

Each organ has specific tasks, ranging from conducting proceedings to conducting investigations and administration.

International Legal Impact and Significance

Beyond its institutional significance, the Rome Statute has set international legal standards in the area of criminal prosecution. Its norm-setting effect extends to the development of national criminal laws, to the practice of international conflict prevention and peacekeeping, and to the strengthening of general international criminal law.

Relationship to Other International Agreements

The provisions of the Rome Statute are, for example, linked with regulations of the Geneva Conventions, the International Criminal Code (VStGB), as well as regional human rights treaties. The obligation of state parties to cooperate (Art. 86 ff. RöSt) underscores the supranational character of the system.

Criticism, Challenges and Further Development

Despite its groundbreaking character, there are ongoing debates and challenges:

  • State sovereignty: Concerns of some states about interference with national independence.
  • Unequal Implementation: Differences in ratification and enforcement among states.
  • Financing and Efficiency of the ICC: Criticism of lengthy proceedings and limited resources.
  • Political Influence: Tensions between the court and individual states in highly political cases.

At the same time, the Rome Statute stands as a symbol of international legal protection and is a central reference point in the debate on global justice.

Literature and Further Information

The Rome Statute is explained in numerous commentaries and is a permanent feature of textbooks on international law. A consolidated text version and up-to-date information can be found on the official website of the International Criminal Court and at the United Nations.

Frequently Asked Questions

What legal obligations arise for state parties to the Rome Statute?

By acceding to the Rome Statute, state parties assume far-reaching international legal obligations. They must implement the provisions of the Statute into their national laws, particularly the criminal law norms relating to the core crimes (genocide, crimes against humanity, war crimes, and aggression). They are also obliged to actively assist the International Criminal Court (ICC) in the prosecution of these crimes. This includes cooperation in investigations, surrender of accused persons, assistance in gathering evidence, seizure of assets, and enforcement of judgments. State parties must also refrain from any acts contrary to the object or purpose of the Statute. Should a state party refuse to cooperate, this may ultimately be reported to the UN Security Council and may result in international legal sanctions.

How is the relationship between national and international prosecution regulated in the Rome Statute?

The Rome Statute primarily regulates the relationship between national and international prosecution by the principle of complementarity. Under Article 17 of the Statute, the International Criminal Court acts subsidiarily, that is, only when national courts are unwilling or unable to conduct genuine investigations and prosecutions of the core crimes. National judicial systems therefore have priority. Only if these fail, for example due to lack of political will, legal obstacles or incapacity, can the ICC act. This principle ensures that state sovereignty is preserved, while at the same time guaranteeing minimum international standards for prosecution.

What legal remedies are available to an accused person before the ICC under the Rome Statute?

The Rome Statute grants accused persons extensive procedural rights and legal remedies. After the conclusion of the main proceedings and the delivery of a judgment, the convicted person may, pursuant to Article 81 of the Statute, appeal against the decision or the sentence. The appeal is considered by a separate chamber of the ICC, which may confirm, overturn, or amend the judgment. Furthermore, the Statute provides for the possibility of a retrial (revision, Article 84) should new material facts become known. During all proceedings, the accused has the right to be heard, to legal representation by a lawyer, and to fair proceedings in accordance with international human rights standards.

How is the jurisdiction of the International Criminal Court established under the Rome Statute?

The jurisdiction of the ICC is conclusively set out in the Rome Statute and subject to specific requirements. It covers only the four core crimes committed after July 1, 2002 (“ratione temporis”). Territorial jurisdiction is established if the crime was committed either on the territory of a state party or by its nationals. In exceptional cases, the United Nations Security Council may also refer cases to the ICC. In order to take action, it is furthermore required that the crime falls within the jurisdiction and that no national prosecution is taking place in the sense of the principle of complementarity.

In what ways are the rights of victims protected in proceedings under the Rome Statute?

The Rome Statute grants victims of crimes, for the first time in international criminal law, explicit and far-reaching rights in criminal proceedings. According to Articles 68 and 75, they can participate as parties to the proceedings, submit motions, directly present their views and concerns, and are not just witnesses. Victims are entitled to protective measures throughout the proceedings, including anonymity or special protection programs. Furthermore, the ICC may order reparations and compensation for victims, which can include the establishment of a special trust fund. Victims also have the right to be informed about the status of proceedings and decisions affecting them.

How does the surrender of a person to the International Criminal Court function under the Rome Statute?

The surrender of accused persons is regulated in detail by the Rome Statute in Articles 89 ff. If a person is arrested in the territory of a state party, a formal extradition procedure applies. The ICC submits a request to the relevant state, which examines the legality of the arrest but generally does not assess the substantive validity of the charges. State parties are obliged to fulfill the surrender request without undue delay. Exceptions exist only in narrowly defined cases, such as when a person is undergoing ongoing national proceedings or diplomatic immunity applies, which is specifically regulated in the Statute. For non-state parties, surrender requires special agreements or a corresponding UN Security Council resolution.
