Compare and contrast the jurisdiction of the International Criminal Court and International Court of Justice. (3%)
Suggested answer only. Not an official answer and not legal advice.
The ICC exercises criminal jurisdiction over individuals for international crimes, whereas the ICJ resolves legal disputes between States and issues advisory opinions.
Under Articles 1, 5, and 17 of the Rome Statute, the ICC tries individuals for genocide, crimes against humanity, war crimes, and aggression under complementarity. Under Articles 34 and 36 of the ICJ Statute, only States may be parties in ICJ contentious cases, and UN organs may request advisory opinions.
Here, ICC jurisdiction attaches to individual criminal liability when domestic courts are unwilling or unable, while ICJ jurisdiction resolves state disputes and advisory questions.
Therefore, the ICC adjudicates individual criminal liability, while the ICJ adjudicates state disputes and legal questions.

1. ICC Individual Jurisdiction
The International Criminal Court (ICC) possesses criminal jurisdiction over natural persons accused of serious international crimes, specifically genocide, crimes against humanity, war crimes, and the crime of aggression under the Rome Statute. Unlike international bodies that resolve state disputes, the ICC focuses exclusively on individual criminal responsibility. Under the principle of complementarity, the ICC acts only as a court of last resort when national judicial systems are genuinely unwilling or unable to investigate or prosecute such crimes.
2. ICJ State Jurisdiction
The International Court of Justice (ICJ) serves as the principal judicial organ of the United Nations, possessing jurisdiction over sovereign States rather than individuals. Under Articles 34 and 36 of the ICJ Statute, the ICJ adjudicates contentious legal disputes submitted by consenting States, such as territorial boundaries, treaty interpretation, and state responsibility. Additionally, authorized UN organs and specialized agencies may request advisory opinions from the ICJ on legal questions, providing authoritative interpretations of international law.
3. Complementarity vs Consent
A key jurisdictional distinction between the ICC and the ICJ lies in their jurisdictional triggers and governance frameworks. The ICC operates under the complementarity doctrine, asserting jurisdiction over individuals when national legal mechanisms fail. In contrast, the ICJ's contentious jurisdiction over States relies strictly on state consent, expressed through special agreements, treaty compromissory clauses, or compulsory jurisdiction declarations under Article 36(2) of the ICJ Statute. Furthermore, the ICJ lacks criminal enforcement authority over individuals.
