Revision summary
The ICJ is the UN’s principal judicial organ under the Charter and the ICJ Statute. Contentious cases lie only between states and only with consent via special agreement, treaty, or optional clause. The Court rules on its own jurisdiction, as in Jadhav under the consular Optional Protocol. Advisory opinions go to authorised UN organs and are not binding judgments. Enforcement depends on states and the Security Council; individuals are not on trial at the ICJ.
Model answer
Introduction
The International Court of Justice is the principal judicial organ of the United Nations under the UN Charter and its own Statute. Jurisdiction is real but consent-based, split between contentious cases between states and advisory opinions, and it is not a criminal court for individuals.
Body
Contentious jurisdiction
- Only states that are parties to the Statute may appear; the Court cannot summon a private person, a rebel group, or a corporation as a respondent.
- Consent is the hinge: it may come from a special agreement, a treaty clause, or an optional-clause declaration under Article 36(2), often riddled with reservations that carve out territory, security, or multilateral treaties.
- Once seised, the Court decides its own competence (compétence de la compétence), as in the Jadhav case where it found jurisdiction under the Optional Protocol to the Vienna Convention on Consular Relations despite Pakistan’s objections.
Advisory jurisdiction
- The General Assembly, the Security Council, and authorised specialised agencies may request advisory opinions; states cannot.
- Advisory opinions are not binding judgments, yet they carry legal and political weight, as in the Nuclear Weapons and Chagos opinions.
Critical limits
- No compulsory world jurisdiction exists; a powerful state can stay outside a case by withholding consent or by a wide reservation.
- The Court has no police of its own; Article 94 lets the Security Council discuss non-compliance, which politics often blocks.
- Mass atrocities and individual guilt sit with the ICC and ad hoc tribunals, not with the ICJ, so “world court” is a misleading label for human-rights enforcement.

Conclusion
ICJ jurisdiction is the most authoritative interstate forum we have, but it is a court of consent, not of command. It can clarify treaties and state responsibility where parties open the door; it cannot police a state that keeps the door shut or try a person for crime.

Can the ICJ try a terrorist or a head of government as a person?
No. Only states are parties in contentious cases. Individual criminal guilt belongs to other courts.

Is an ICJ judgment automatically enforced in every capital?
No. Parties are obliged to comply, but there is no ICJ police; the Security Council may be seized under Article 94, subject to veto politics.

Why is India opposed to mediation on Kashmir?
Indian Constitution
India treats Jammu and Kashmir as an integral Union subject after accession in 1947. Simla 1972 and later bilateral texts require peaceful settlement without a mediator. Mediation would internationalise what New Delhi now frames as an internal constitutional and security issue. Pakistan is a counterpart for talks on terror and peace, not a co-sovereign over Indian territory. India therefore rejects UN, great-power, or other good-offices formulas that write a Kashmir settlement.

Throw light on the challenges and problems of farmers and the agriculture sector in Uttar Pradesh. Suggest measures for improvement.
Social sector services
Uttar Pradesh leads in foodgrain output but farm incomes stay low on tiny holdings and uneven water. Eastern floods and Bundelkhand droughts sit beside western groundwater stress and cane-payment delays. Paddy–wheat lock-in and thin mandi–FPO reach keep farmers as price-takers. Remedies are last-mile irrigation, statutory cane dues, FPO and e-NAM markets, and a shift to pulses, millets, milk, and processing. Land-lease clarity and working crop insurance must travel with those measures.

What are electoral bonds? Are they capable of bringing transparency in the political funding system?
Transparency, accountability and e-governance
Electoral bonds were 2018 SBI instruments bought with KYC and gifted to registered parties. The donor’s name did not appear in the public contribution trail. Finance Act 2017 changes enabled unlimited corporate giving and weaker disclosure. Opacity was asymmetric if the state could still infer donors while voters could not. The Supreme Court in 2024 held the scheme unconstitutional for violating Article 19(1)(a).
