Core ICC texts

The core legal texts are the seven documents that together form the basis of the Court’s legal framework: the Rome Statute of the International Criminal Court (Statute), the Rules of Procedure and Evidence, the Elements of Crimes, the Regulations of the Court, the Regulations of the Registry, the Regulations of the Office of the Prosecutor and the Code of Professional Conduct for counsel. The most important of these, and first to be adopted and enter into force, was the Statute, following which the remaining six texts entered into force at various points during the Court’s history. All can be amended according to their own particular amendment procedure.

Rome Statute of the International Criminal Court

The Rome Statute of the International Criminal Court is the international treaty that founded the Court. Comprising a Preamble and 13 Parts, it establishes the governing framework for the Court. Adopted at the Rome Conference on 17 July 1998, it entered into force on 1 July 2002, thereby creating the International Criminal Court. See our history.

The Statute sets out the Court's jurisdiction over genocide, crimes against humanity, war crimes and – as of an amendment in 2010 – the crime of aggression. In addition to jurisdiction, it also addresses issues such as admissibility and applicable law, the composition and administration of the Court, investigations and prosecution, trials, penalties, appeal and revision, international cooperation and judicial assistance, and enforcement.

Code of Conduct for the Office of the Prosecutor


Code of Judicial Ethics

The Code of Judicial Ethics provides guidelines for general application to contribute to judicial independence and impartiality with a view to ensuring the legitimacy and effectiveness of the judicial process. To this effect the Code contains guidelines on the conduct of Judges relating both to their professional roles, for example by acting with integrity, respecting confidentiality and regulating the conduct of those participating in courtroom proceedings, and in their activities outside the Court.

Chambers Practice Manual

24 November 2022 - English, Français


This update of the Chambers Practice Manual, resulting from collective discussions held at the Judges’ retreat near Arnhem (Netherlands) on 3-4 October 2019 and drawing on the preparatory work undertaken by a number of judges on this issue, adds a number of specific deadlines for rendering diverse types of decisions and judgments.

These guidelines for the timing of key judicial decisions now introduce a coherent, consistent and predictable system of timeframes regulating work at pre-trial, trial and appeal level.

They aim to achieve a significant step forward in respect of the efficiency and expeditiousness of Court proceedings.

Previous editions of the Manual

Guidelines for the Judiciary Concerning the Holding of Court Hearings during the COVID-19 Pandemic

The Guidelines are facilitative and non-binding, aiming to provide clarity on the Court’s approach to holding hearings in Court proceedings during the COVID-19 Pandemic. The Guidelines emphasise that the applicable Chamber may decide independently whether required hearings should be conducted physically, remotely or as a combination of both. A Chamber should consider the rights and protections guaranteed in the Rome Statute and the Rules of Procedure and Evidence, as well as giving due consideration to the situations and restrictions in states where parties or participants in the hearings are located.

The Staff Regulations

The Staff Regulations were adopted by the Assembly of States Parties, in accordance with article 44(3) of the Rome Statute. They broadly outline the principles and policies that apply to all Court staff. They do not apply to elected officials such as the Judges, the Prosecutor and the Registrar. The Regulations provide for the duties, obligations and privileges of Court staff and establish guidelines for matters such as the classification of posts and staff, salaries and allowances, appointment and promotion of staff, leave entitlements, social security, staff expenses, staff relations, separation of service, disciplinary measures, appeal of administrative decisions and recruitment.

Staff rules of the International Criminal Court

The Staff Rules of the International Criminal Court elaborate on the Staff Regulations and apply to all staff members with a fixed-term appointment including, subject to another resolution, to staff of the Secretariat of the Assembly of States Parties. They provide more detailed provisions on the issues dealt with in the Regulations.

The Financial Regulations and Rules

The Financial Regulations and Rules were adopted by the Assembly of States Parties in accordance with article 113 of the Rome Statute and outlines the rules and regulations that govern the financial administration of the Court. The Regulations deal with matters such as the creation of a proposed budget for approval by the Assembly of States Parties, appropriations, the provision of and management of funds and other income, internal control of the Court’s finances, accounting methods and auditing of the Court’s accounts. The Rules elaborate on these by providing detail on how the Regulations are to be implemented. An annex to the Rules and Regulations sets out the terms of reference for the auditor appointed by the Assembly of States Parties to audit the Court.

The Agreement on the Privileges and Immunities of the International Criminal Court

This Agreement between States Parties elaborates on articles 4 and 48 of the Rome Statute that refer to the legal personality of the Court and its privileges and immunities in the territory of States Parties. The Agreement provides that the Court’s premises, archives, documents and communications are inviolable; that its property, funds and assets are immune from legal processes and it is exempt from taxes and customs. The Agreement also details the immunities that various groups of personnel working with or attending the Court, such as Representatives at the Assembly of States Parties, Judges, Counsel, Witnesses and Victims, are entitled to.

The Agreement between the International Criminal Court and the United Nations

This Agreement was concluded pursuant to article 2 of the Rome Statute in order to provide for a mutually beneficial relationship between the two organisations. This is done through recognition of and respect for each other’s mandates, reciprocal representation, exchange of information and cooperation between the organisations on matters of personnel, administration, facilities and services, including access to UN venues.

The Headquarters Agreement with the Host State

This Agreement was concluded between the Court and the Netherlands to regulate matters regarding the establishment of the Court in The Hague. It aims to ensure the stability, independence and smooth functioning of the Court and the Secretariat of the Assembly of States Parties in the Netherlands. In addition to detailing the immunities and privileges that the Court and its officials, staff and related personnel enjoy, the Headquarters Agreement regulates the provision of services, such as electricity, water and fire protection to the Court as well as security of the Court premises and its personnel. It also deals with the facilitation of entry into the Netherlands of those required to travel to the Court, visitors of detainees and other stakeholders, such as NGOs and press and contains provisions regulating the transport, detention and release (interim or otherwise) of detainees.

Legal Tools

The Legal Tools Project aspires to equip users with the legal information, digests and software required to work effectively with international criminal law.

It seeks to serve as a complete virtual library on international criminal law and justice. The Tools comprise the largest online collection of relevant documents and legal digests available through the Case Matrix application. Some 13 collections of legal documents are included, together with four legal research and reference tools developed by lawyers connected with the Court and external partners: the Case Matrix, the Elements Digest, the Proceedings Digest and the Means of Proof Digest.

Administrative Issuances

It provides a comprehensive index of all documents covered: with 31 categories and more than 400 sub-categories, the Index maps all relevant sources governing the Court's administration, from Human Resources issues to professional conduct, security, procurement, etc. 

Guidelines on intermediaries

The ICC uses the below guidelines in interacting with intermediaries, particularly those entities and individuals that support the Court's activities, particularly local actors in the field, who assist with, among other activities, the safety of victims and witnesses.

With the exception of the model contract, these guidelines are not legally binding. They include a built-in review mechanism for amending as required.

The aim of the Guidelines is fourfold:

  • to preserve the integrity of the judicial process to the maximum extent possible;
  • to provide guidance to staff of the Court and improve efficiency of the Court's operations;
  • to provide transparency and clarity for third parties who may interact with the organs or units of the Court or Counsel; and
  • to provide guidance on the relationship between the Court and intermediaries.
