The ICJ handles two types of cases:
Contentious Cases: These involve legal disputes between States that have agreed to submit their issues to the Court.
Advisory Proceedings: The Court provides advisory opinions on legal questions brought by UN organs or specialized agencies.
Only Sovereign States can be parties in contentious cases. The ICJ can hear a case only if the involved States have accepted its jurisdiction in one of the following ways:
Special Agreement: Both States involved agree to bring the dispute to the ICJ.
Jurisdictional Clause: A treaty may contain a provision that allows disputes to be referred to the ICJ.
Compulsory Jurisdiction: Some States accept the Court’s jurisdiction in advance through declarations submitted to the UN Secretary-General. These declarations may include certain reservations that exclude specific types of disputes.
Representation & Court Proceedings
States do not have permanent representatives at the ICJ. Instead, they communicate through their Ministers of Foreign Affairs or Ambassadors. In Court proceedings, each State appoints an Agent who acts as its legal representative. Agents coordinate legal arguments, file necessary documents, and present oral arguments before the Court.
Proceedings in contentious cases follow a structured process:
Initiating Proceedings: A case can begin with a special agreement (joint submission by both States) or a unilateral application (one State initiates a case against another).
Written & Oral Phases: The written phase involves submitting legal pleadings and supporting documents. The oral phase includes public hearings where legal representatives present their cases.
Final Judgment: The ICJ deliberates privately before delivering a final, binding judgment in a public session. Judgments cannot be appealed but may be subject to interpretation or revision under exceptional circumstances.
If a State fails to comply with an ICJ ruling, the UN Security Council may take measures to ensure enforcement.
The ICJ also provides advisory opinions on legal questions referred by:
- The UN General Assembly and Security Council (on any legal issue).
- Other UN organs and specialized agencies, but only on questions within their mandate.
Advisory Proceedings Process
Request Submission: The requesting organization submits a legal question to the Court.
Gathering Information: The ICJ identifies States and organizations that can provide relevant legal insights. Written and oral proceedings are conducted, similar to contentious cases.
Delivery of Advisory Opinion: The ICJ delivers its opinion in a public session. While not legally binding, these opinions carry significant authority in international law.
The International Court of Justice plays a vital role in maintaining global peace and justice. Through contentious cases, it settles disputes between States, and via advisory proceedings, it offers legal guidance to international organizations. Its decisions uphold international law, promoting fairness and cooperation among nations.
