Revision summary
The ICJ is the UN’s principal judicial organ, with 15 judges elected by the Assembly and the Council. Contentious cases are between States that have consented to jurisdiction. Advisory opinions answer legal questions from authorised UN bodies. Article 38 lists the sources the Court applies. Enforcement of judgments can go to the Security Council, which limits the Court against the P5.
Model answer
Introduction
The International Court of Justice is the principal judicial organ of the United Nations. It sits at The Hague under the UN Charter and its own Statute. It settles legal disputes between States and gives advisory opinions to authorised UN organs.
Body
Structure
- The Court has 15 judges elected for nine-year terms by the General Assembly and the Security Council, voting separately.
- Five seats are filled every three years. No two judges may be nationals of the same State.
- Chambers, including a Chamber of Summary Procedure, may sit for particular cases.
- Only States may be parties in contentious cases. International organisations are not litigants there.
- The Registry is the permanent secretariat. Official languages are English and French.
Functions
- Contentious jurisdiction decides legal disputes when States consent, by special agreement, by a treaty clause, or by an optional-clause declaration under the Statute.
- Advisory jurisdiction answers legal questions put by the General Assembly, the Security Council, or other authorised organs and specialised agencies.
- The Court applies treaties, custom, general principles, and, as subsidiary means, judicial decisions and teachings of publicists, as listed in Article 38 of the Statute.
- Judgments are binding on the parties to that case. Article 94 of the Charter allows a party to seek Security Council action if the other side fails to comply.
Limits
- Consent is the gate. Powerful States often withhold it or ignore political disputes that they refuse to treat as legal.
- The Security Council’s enforcement role means the Court cannot police the P5 by itself.
- Advisory opinions are not judgments, though they carry legal and political weight.

Conclusion
The ICJ is a 15-judge UN court for inter-State law and for advisory opinions. Its structure is elective and professional. Its functions depend on State consent and, for enforcement, on a Security Council that is itself political.

Critically examine India's persistent refusal to sign the nuclear non-proliferation treaty (NPT) despite being recognized as a de facto nuclear power.
Contemporary Global Concerns
The NPT recognises five weapon states and asks others to stay non-nuclear; India rejected this as nuclear apartheid. China–Pakistan nuclear conditions and empty P5 disarmament made signature look like unilateral abstinence. There is still no legal path for India to join as a weapon state; the 2008 waiver worked around the treaty. Persistent refusal is therefore structural, not mood. Costs remain in export controls and non-proliferation politics; a test moratorium and minimum deterrence are how India manages them.

Contemporary Global Concerns
Global South diplomacy continues NAM and G77 in a new institutional setting. India hosted South summits and used G20 2023 to seat the African Union. ITEC, credit, vaccines, and UN peacekeeping are the material side. WTO food and IP fights remain part of the same file. China’s finance is the main competitor for Southern attention.

Contemporary Global Concerns
The NPT recognises only five nuclear-weapon States by a 1967 date. India rejected that hierarchy as unequal law. China’s arsenal and later Pakistan made accession a security risk. 1974 and 1998 locked a weapons-capable identity. A US-led NSG waiver later gave civilian trade without signature.
