International Court of Justice: Composition, Election, and Judicial Structure
The International Court of Justice (ICJ) serves as the principal judicial organ of the United Nations, designed to settle legal disputes between states and provide advisory opinions. To maintain its legitimacy and authority, the Court relies on a diverse composition of legal experts and a rigorous election process that balances geopolitical interests with judicial independence.
Key Facts
- Composition: 15 judges elected to nine-year terms.
- Diversity: No two judges may be nationals of the same country.
- Election: Candidates must win an absolute majority in both the UN General Assembly and the UN Security Council.
- Independence: Judges are prohibited from holding other professional occupations or political functions.
- Ad Hoc Judges: Parties to a case may appoint a temporary judge if they do not have a national on the bench.
The Composition of the Court
The ICJ consists of fifteen judges who serve nine-year terms. According to Article 3 of its statute, no two judges can share the same nationality. Article 9 further mandates that the membership represent the principal legal systems of the world and the main forms of civilization. In practice, this includes a blend of common law, civil law, socialist law, and Islamic law.
While not formally codified, an informal geographic distribution governs the seats to ensure global representation:
- Western countries: 5 seats
- Asian states: 3 seats
- African states: 3 seats (typically divided among Francophone civil law, Anglophone common law, and Arab representatives)
- Eastern European states: 2 seats
- Latin American and Caribbean states: 2 seats
Historically, the five permanent members of the UN Security Council (China, France, Russia, the UK, and the US) usually held seats. However, this has not always been the case. For example, China had no judge from 1967 to 1985, the UK has lacked a judge since 2018, and Russia has had no judge since 2024. Gender representation has also evolved slowly; as of August 2026, only seven women have been elected, with the first, Rosalyn Higgins, joining in 1995.

Nomination and Election Procedures
The Nomination Process
Candidates are nominated by individuals serving on the Permanent Court of Arbitration (PCA), acting in "national groups." If a UN member state is not represented in the PCA, it may appoint up to four individuals to form a national group. Each group can nominate up to four candidates, with a maximum of two being their own nationals. National groups are encouraged to consult with their highest courts, law schools, and national legal academies before submitting names.
The Election Process
Elections are staggered, with five judges elected every three years to ensure continuity. To be elected, a candidate must obtain an absolute majority of votes in both the UN General Assembly and the UN Security Council, acting independently.
An absolute majority is defined as a majority of all eligible electors, regardless of whether they vote. For instance, in the General Assembly (with 193 members as of July 2026), 97 votes are required. In the Security Council, eight votes are required.
If the two bodies cannot agree on the same candidates after three meetings, a joint conference of six members (three from each organ) may be formed to resolve the vacancies. If this fails, the existing judges of the ICJ fill the seats by selecting from candidates who received votes in either the Assembly or the Council.
Qualifications and Judicial Independence
Judges must be persons of high moral character who are either qualified for the highest judicial office in their own country or recognized as lawyers with sufficient competence in international law. To ensure impartiality, judges are prohibited from exercising political or administrative functions or engaging in other professional occupations.
Furthermore, judges cannot participate in any case where they previously served as an agent, counsel, or member of a commission of inquiry. While some judges have historically engaged in outside arbitration, current members have called for stricter limits on such "moonlighting." A judge can only be dismissed through a unanimous vote of their peers.
Special Judicial Arrangements
Ad Hoc Judges
Under Article 31, a party to a contentious case may appoint an ad hoc judge if they do not have a national already serving on the Court. This allows up to 17 judges to sit on a single case. The purpose is to encourage states to submit to the Court's jurisdiction by ensuring their perspective and local knowledge are represented during deliberations.
Chambers
While the Court usually sits as a full bench, it can form smaller chambers of 3 or 5 judges. These can be special chambers for specific categories of cases (such as an unused environmental chamber established in 1993) or ad hoc chambers for particular disputes, such as the Gulf of Maine Case between Canada and the US.

Frequently Asked Questions
How are ICJ judges elected?
Judges are elected through independent voting processes in the UN General Assembly and the UN Security Council. A candidate must receive an absolute majority of votes in both organs to be appointed.
What is an ad hoc judge?
An ad hoc judge is a temporary judge appointed by a party to a specific case if that party does not have a national already serving as a permanent judge on the Court.
Can a judge be removed from the ICJ?
Yes, but only if there is a unanimous vote by the other members of the Court to dismiss them.
Why is geographic distribution important for the ICJ?
Geographic distribution ensures that the Court represents the world's main forms of civilization and principal legal systems, which enhances the legitimacy of its rulings on a global scale.
What happens if the General Assembly and Security Council cannot agree on a judge?
If they fail to agree after three meetings, they may form a joint conference of six members. If that also fails, the existing judges of the ICJ will select the remaining members from the candidates who received votes.
