GS-II — Important international institutions, agencies and fora; effect of global politics on India’s interests.

Introduction

Modern wars, climate disputes, and repeated deadlocks in the Security Council show both the weaknesses and the necessity of international law. It rarely operates like domestic law. Yet, it provides the **rules, legitimacy, and institutional language** through which states cooperate, challenge actions, and assign responsibility.

Historical Evolution

International law developed over time. It evolved from rules among sovereign states. Later, it included institutions governing individuals, global common resources, and shared risks.

  1. 1648: The Peace of Westphalia became a traditional marker for the sovereign-state system.
  2. 1899 and 1907: The Hague Conferences codified rules for warfare and peaceful dispute settlement.
  3. 1945: The UN Charter prohibited the use of force, except under limited Charter grounds, and established the ICJ.
  4. 1948: The Universal Declaration of Human Rights made the protection of individual dignity an international concern.
  5. 1969: The Vienna Convention on the Law of Treaties codified rules for forming and interpreting treaties.
  6. 1998–2002: The Rome Statute created the International Criminal Court and entered into force.
  7. 2023–2026: The BBNJ Agreement was adopted, reached its ratification threshold, and entered into force.

Pillars of Cooperation

International law performs three important functions: creating predictable norms, settling disputes, and enabling cooperation over shared spaces and risks.

Predictability and Norm Creation

  • Treaty obligations: Agreed rules reduce uncertainty in diplomacy, trade, environmental matters, and security.
  • Customary international law: General practices accepted as law bind actions even beyond specific treaties.
  • Good-faith performance: Pacta sunt servanda means compliance is the basic expectation in treaty relations.

Dispute Settlement and Accountability

  • International Court of Justice: It decides disputes between consenting states and gives advisory opinions.
  • Specialised mechanisms: WTO panels, arbitration, and maritime tribunals provide specific adjudication for their domains.
  • Individual responsibility: International criminal law does not allow complete freedom from punishment for grave crimes.
The ICJ’s 23 July 2025 climate advisory opinion clarified state obligations.

The Court addressed states’ duties regarding climate change under international law. This strengthened the legal language for prevention, cooperation, and responsibility. Advisory opinions are not judgments between disputing states. However, they can influence negotiations and domestic legal cases. ICJ proceedings

Global Commons and Functional Cooperation

  • Law of the sea: UNCLOS assigns maritime rights while protecting navigation and shared spaces.
  • Climate and environment: Treaties organise collective action when harm crosses borders.
  • Technical regimes: Rules for aviation, telecommunications, health, and postal services enable routine global coordination.
The BBNJ Agreement makes high-seas biodiversity governance operational.

The Agreement entered into force on 17 January 2026. It covers marine genetic resources, area-based management, environmental assessment, and capacity-building. As of 3 September 2026, the UN treaty status page listed 145 signatories and 93 parties. India had signed on 25 September 2024 but had not ratified it. UN BBNJ portal

Areas of Friction

International law is mainly weakened by limits on consent, decentralised enforcement, power imbalances, and institutional vetoes.

Jurisdiction and Consent

State consent limits compulsory adjudication.

Courts and tribunals usually require consent based on a treaty or specific agreement. This allows powerful states to avoid or narrow their jurisdiction. Therefore, a legal obligation may exist without an immediately available judicial forum.

Enforcement and Power

Decentralised enforcement makes compliance uneven.

International law lacks a universal police or executive authority. Compliance depends on reciprocity, reputation, domestic institutions, sanctions, and collective political action. These factors work differently in various cases.

Power asymmetry produces selective accountability.

Stronger states can more easily absorb costs, shape institutions, or gather allies than weaker states. This selectivity harms legitimacy, even if the underlying norm remains valid.

Institutional Gridlock

Security Council vetoes can block collective enforcement.

Permanent members may prevent binding Council action when their interests or allies are involved. This creates a gap between universal Charter rules and politically selective enforcement.

Fragmented regimes can create overlapping or conflicting obligations.

Trade, investment, human rights, security, and environmental bodies may apply different standards to the same actions. Therefore, coordination and consistent treaty interpretation are becoming increasingly important.

India's Strategic Interests

India’s interest lies in a rule-based order. This order should protect sovereignty and development. It should also reform institutions that maintain unequal power.

UNCLOS protects navigation and India’s maritime entitlements.

Predictable rules for exclusive economic zones, continental shelves, and sea-lane access support trade, energy, and security. India benefits from upholding these rules. It does so even while challenging interpretations through lawful processes.

Counter-terrorism law supports accountability across borders.

Extradition, terror-financing, and sanctions regimes help address networks operating beyond one jurisdiction. India also seeks less politicised mechanisms for listing and enforcement.

Developmental equity must shape climate and ocean obligations.

India supports environmental responsibility. It also supports common but differentiated responsibilities, finance, technology, and capacity-building. Its BBNJ signature reflects support for ocean governance. Ratification, however, remains a sovereign legislative choice. MEA response on BBNJ

UN reform is necessary for representative multilateralism.

India seeks a permanent Security Council role and greater representation for the Global South. Reform would reduce the legitimacy gap. This gap exists between current power realities and institutions designed in 1945.

Way Forward

Reform must improve compliance and representation. It should do so without discarding the common rules. Weaker and middle powers especially rely on these rules.

Strengthen domestic implementation of treaty obligations.

Legislation, judicial interpretation, and administrative capacity convert international commitments into practical compliance. Parliamentary scrutiny should clarify obligations before ratification and during implementation.

Expand acceptance of impartial dispute-settlement mechanisms.

Clear jurisdiction clauses, arbitration, and compliance procedures reduce unilateral interpretation. States can maintain carefully defined reservations. At the same time, they can accept stronger baseline review.

Restrain veto use in mass-atrocity situations.

Voluntary veto-restraint initiatives can reduce paralysis even before Charter amendment. The larger goal is a more representative Security Council. This Council should have greater accountability for inaction.

Finance legal capacity and technology transfer for developing states.

Equal rules do not create equal ability to negotiate, monitor, or litigate. BBNJ capacity-building provisions show how substantive fairness can be built into a legal system.

This quotation can conclude an answer. It presents law as a constraint on power, not a denial that power matters. See also the WayToIAS analysis on enforcement limits and multilateral cooperation.

Answer Framework

  • Introduction: Frame international law as essential but decentralised.
  • Body: Explain norm creation, adjudication, and cooperation. Then, analyse consent, enforcement, power, and vetoes.
  • India angle: Use maritime security, counter-terrorism, developmental equity, and UN reform.
  • Conclusion: Argue for stronger domestic compliance, fairer institutions, and wider peaceful dispute settlement.
