Does the International Court of Justice Have Jurisdiction? A Checker
Only states can be parties to contentious cases before the International Court of Justice, and the Court can hear a case only if both states have consented to its jurisdiction. Consent can be given by a special agreement to submit a particular dispute, by a compromissory clause in a treaty, by declarations accepting the Court’s jurisdiction as compulsory under the optional clause (valid only to the extent that the declarations overlap, so a reservation by one state can be invoked by the other), or by conduct after an application (forum prorogatum). Even with jurisdiction, the claim must be admissible: for example, local remedies must be exhausted where required, and the Court will not decide the rights of a third state that is not before it.
Tool · ICJ Jurisdiction Checker
The Court probably has jurisdiction and the claim is admissible.
Parties are states: Both parties are states that may appear before the Court.
A legal dispute: There is a genuine dispute: a disagreement on a point of law or fact, positively opposed by the other side.
Consent: compromissory clause: A treaty in force between the parties refers disputes about its interpretation or application to the Court, and the conditions of the clause (such as a prior attempt at negotiation) have been met and the dispute falls within it.
Admissibility: Even with jurisdiction, the claim must be admissible.
- Only states may be parties in contentious cases (Article 34 of the Statute). Consent is the foundation of the Court’s jurisdiction: a state cannot be brought before it without having accepted its jurisdiction in some way (Monetary Gold; East Timor).
- A judgment binds only the parties and only in respect of that case (Article 59). If a party fails to comply, the other may go to the Security Council, which may make recommendations or decide on measures (Article 94(2) of the Charter), where the veto may prevent action.
Walks through whether the International Court of Justice can hear a case between states: the parties, a real dispute, a basis of consent (special agreement, compromissory clause, optional-clause declarations or forum prorogatum) and then admissibility. Invented facts and simplified rules; consent and admissibility are decided on the detailed treaties, declarations and conduct. A teaching aid, not legal advice.

Common questions
Can individuals or companies bring a case before the ICJ?
No. Only states may be parties in contentious cases. A state may take up a claim on behalf of a national through diplomatic protection.
Are the Court’s judgments enforceable?
They bind the parties in the case. If a party does not comply, the other may go to the Security Council, where the veto can prevent action.
What is a compromissory clause?
A clause in a treaty that refers disputes about its interpretation or application to the Court. It gives jurisdiction only for disputes within its scope and after any conditions, such as negotiation, are met.
