BharatNotes Sources of International Law
International law governs relations between sovereign states and international organisations. Article 38(1) of the Statute of the International Court of Justice is the authoritative statement on the sources of international law.
Primary Sources (Article 38, ICJ Statute)
| Source | Description |
|---|---|
| International treaties and conventions | Formal written agreements between states — the most prominent source of international law and the only source available to states wanting to formally enter into legal relations |
| International custom | General practice accepted as law — requires two elements: consistent state practice and opinio juris (acceptance of the practice as legally obligatory) |
| General principles of law | Principles recognised by civilised nations — inserted as "gap fillers" by drafters of the PCIJ Statute for situations where treaties and customs were insufficient |
Secondary (Subsidiary) Sources
| Source | Role |
|---|---|
| Judicial decisions | Decisions of international courts and tribunals — subsidiary means for determination of rules of law |
| Teachings of publicists | Writings of highly qualified scholars — used for interpretation and identification of rules |
For Mains: Article 38(1) is not an exhaustive list. Resolutions of the UN General Assembly, acts of international organisations, and unilateral declarations by states can also create binding obligations. The ICJ has increasingly relied on customary international law alongside treaties.
International Court of Justice (ICJ)
Structure and Composition
| Feature | Detail |
|---|---|
| Established | 1945, as the principal judicial organ of the United Nations |
| Seat | Peace Palace, The Hague, Netherlands |
| Judges | 15 judges elected for 9-year terms by the UN General Assembly and Security Council |
| Quorum | 9 judges required; no two judges may be nationals of the same state |
| Ad hoc judges | Parties to a dispute may appoint an ad hoc judge if no judge of their nationality sits on the bench |
| Official languages | English and French |
Jurisdiction
| Type | Scope |
|---|---|
| Contentious cases | Only states (not individuals or organisations) can be parties; jurisdiction requires consent of both parties |
| Advisory opinions | Given at the request of the UN General Assembly, Security Council, or other authorised UN organs and agencies |
| Compulsory jurisdiction | States may accept compulsory jurisdiction under Article 36(2) — the "Optional Clause"; approximately 73 states have done so |
| Binding nature | Judgments in contentious cases are binding on the parties; advisory opinions are non-binding but carry significant authority |
India and the ICJ
| Case | Year | Key Details |
|---|---|---|
| Corfu Channel (intervener) | 1949 | India participated as an intervener in early ICJ proceedings |
| Right of Passage over Indian Territory | 1960 | Portugal vs India — Court ruled India had the right to regulate passage to Portuguese enclaves in Goa |
| Trial of Pakistani Prisoners of War | 1973 | Pakistan filed against India over PoWs from the 1971 war; case removed from the list by mutual agreement |
| Aerial Incident of 10 August 1999 | 2000 | Pakistan filed over the shooting down of its Atlantique aircraft; ICJ ruled it lacked jurisdiction as Pakistan had not accepted compulsory jurisdiction |
| Jadhav Case (India v. Pakistan) | 2017–2019 | India's most significant ICJ case in recent history |
The Jadhav Case (India v. Pakistan) — 2019
| Aspect | Detail |
|---|---|
| Background | Kulbhushan Sudhir Jadhav, an Indian national, was arrested by Pakistan in 2016 and sentenced to death by a Pakistani military court in April 2017 on charges of espionage and terrorism |
| India's application | Filed on 8 May 2017, alleging violations of the Vienna Convention on Consular Relations (1963) — Pakistan had denied consular access to Jadhav |
| Provisional measures | On 18 May 2017, the ICJ unanimously ordered Pakistan not to execute Jadhav pending a final decision |
| Hearings | Public hearings on the merits held from 18 to 21 February 2019 |
| Judgment date | 17 July 2019 |
| Key finding | Pakistan had breached its obligation under Article 36(1)(b) of the Vienna Convention by failing to inform Jadhav of his right to consular access "without delay" |
| Remedy ordered | Pakistan must provide effective review and reconsideration of the conviction and sentence, ensuring full weight is given to the effect of the Vienna Convention violation |
| Pakistan's defence rejected | The Court held the Vienna Convention was applicable "regardless of the allegations that Mr. Jadhav was engaged in espionage activities" |
| Vote | 15-1 on the question of consular access violation |
For Prelims: The ICJ's judgment in the Jadhav case (2019) was based on the Vienna Convention on Consular Relations, 1963 — not the Vienna Convention on Diplomatic Relations, 1961. These are two separate treaties.
International Criminal Court (ICC)
Structure and Key Facts
| Feature | Detail |
|---|---|
| Established by | Rome Statute, adopted on 17 July 1998; entered into force on 1 July 2002 |
| Seat | The Hague, Netherlands |
| States Parties | 124 countries as of 2025 — 33 African, 19 Asia-Pacific, 20 Eastern European, 28 Latin American and Caribbean, 25 Western European and other states |
| Jurisdiction | Genocide, crimes against humanity, war crimes, and the crime of aggression |
| Principle | Complementarity — the ICC acts only when national courts are unwilling or unable to genuinely investigate or prosecute |
| Prosecutor | Karim A.A. Khan (since 2021) |
India's Position on the ICC
| Aspect | India's Stance |
|---|---|
| Signatory status | India is NOT a party to the Rome Statute — it abstained from the vote at the Rome Conference in 1998 |
| Other non-members | USA, China, Russia, and Israel are also not parties |
| Key concerns | Potential interference with sovereignty; broad powers of the Prosecutor to initiate investigations proprio motu; concerns about the definition of crimes being too wide; no adequate safeguards against politically motivated prosecutions |
| Cooperation | India cooperates with international tribunals on a case-by-case basis |
For Mains: India's non-membership of the ICC does not mean India opposes accountability for international crimes. India has supported ad hoc tribunals (ICTY for Yugoslavia, ICTR for Rwanda) and consistently advocates for rule-based international order. India's objection is to the specific institutional design of the ICC, not to the principle of international criminal justice.
UNCLOS — United Nations Convention on the Law of the Sea
Overview
| Feature | Detail |
|---|---|
| Adopted | 10 December 1982 at Montego Bay, Jamaica |
| Entered into force | 16 November 1994 |
| States Parties | 169 states and the European Union as of 2025 |
| Often called | "Constitution of the Oceans" |
| India's ratification | India signed UNCLOS in 1982 and ratified it on 29 June 1995 |
Maritime Zones Under UNCLOS
| Zone | Extent from Baseline | Key Rights |
|---|---|---|
| Internal Waters | Landward of the baseline | Full sovereignty — equivalent to territory on land |
| Territorial Sea | Up to 12 nautical miles (nm) | Full sovereignty, subject to right of innocent passage for foreign vessels |
| Contiguous Zone | 12–24 nm | Enforcement jurisdiction for customs, fiscal, immigration, and sanitary laws |
| Exclusive Economic Zone (EEZ) | Up to 200 nm | Sovereign rights for exploration, exploitation, conservation, and management of natural resources (living and non-living) |
| Continental Shelf | Up to 200 nm (extendable to 350 nm in certain conditions) | Sovereign rights over the seabed and subsoil for resource exploitation |
| High Seas | Beyond 200 nm EEZ | Freedom of navigation, overflight, fishing, scientific research — common heritage of mankind |
| The Area | Seabed beyond national jurisdiction | International Seabed Authority (ISA) manages mineral resources as "common heritage of mankind" |
India and UNCLOS
| Aspect | Detail |
|---|---|
| India's EEZ | Approximately 2.37 million sq km — India has the 18th largest EEZ in the world |
| Coastline | 7,516 km (including island territories of Andaman & Nicobar and Lakshadweep) |
| Continental shelf claim | India submitted a claim to the Commission on the Limits of the Continental Shelf (CLCS) in 2009 for an extended continental shelf beyond 200 nm |
| Deep sea mining | India holds exploration rights for polymetallic nodules in the Central Indian Ocean Basin (allotted by ISA in 2002) |
| Maritime disputes | India resolved its maritime boundary with Bangladesh through the Permanent Court of Arbitration (2014) — "Bay of Bengal Maritime Boundary Arbitration" |
| Legislation | Maritime Zones of India Act, 1976 (predates UNCLOS but largely consistent); Territorial Waters, Continental Shelf, EEZ and Other Maritime Zones Act |
High Seas Treaty (BBNJ Agreement)
The Agreement on Biodiversity Beyond National Jurisdiction (BBNJ Agreement), also called the High Seas Treaty, was adopted in June 2023. India signed the treaty and is working towards formal ratification, which requires amendments to the Biological Diversity Act.
For Prelims: UNCLOS defines six maritime zones. India's EEZ extends to 200 nm and covers approximately 2.37 million sq km. The International Seabed Authority (ISA), headquartered in Kingston, Jamaica, regulates deep sea mining in "The Area" beyond national jurisdiction.
Geneva Conventions and International Humanitarian Law (IHL)
The Four Geneva Conventions of 1949
| Convention | Protects |
|---|---|
| First Geneva Convention | Wounded and sick soldiers on land (amelioration of the condition of the wounded and sick in armed forces in the field) |
| Second Geneva Convention | Wounded, sick, and shipwrecked members of armed forces at sea |
| Third Geneva Convention | Prisoners of war — defines their rights and standards for treatment |
| Fourth Geneva Convention | Civilian persons in time of war — protection of civilians in and around a war zone |
Additional Protocols
| Protocol | Year | Subject |
|---|---|---|
| Additional Protocol I | 1977 | Protection of victims of international armed conflicts — strengthens the Fourth Geneva Convention |
| Additional Protocol II | 1977 | Protection of victims of non-international (internal) armed conflicts — expands on Common Article 3 |
| Additional Protocol III | 2005 | Adoption of an additional distinctive emblem — the Red Crystal (alongside the Red Cross and Red Crescent) |
Key Principles of IHL
| Principle | Meaning |
|---|---|
| Distinction | Parties must distinguish between combatants and civilians; attacks may only be directed at military objectives |
| Proportionality | Attacks must not cause civilian harm excessive in relation to the military advantage anticipated |
| Military necessity | Force may only be used to the extent necessary to achieve a legitimate military purpose |
| Humanity | Suffering must be minimised; superfluous injury and unnecessary suffering are prohibited |
| Common Article 3 | Minimum protections applicable in all armed conflicts (international and non-international) — prohibits violence to life, torture, hostage-taking, and outrages upon personal dignity |
Ratification Status
The four Geneva Conventions of 1949 are among the most universally ratified treaties in history — 196 states are parties, covering virtually every country in the world. India is a party to all four Geneva Conventions. India has not ratified Additional Protocol I or Additional Protocol II — India's Ministry of External Affairs confirmed in 2019 that no decision has been taken to ratify either Additional Protocol.
For Mains: Common Article 3 is sometimes called a "mini-convention" within the Geneva Conventions because it applies to all armed conflicts, including internal conflicts. It establishes the absolute minimum standards of humanitarian treatment. The ICRC (International Committee of the Red Cross) is the guardian of IHL.
Extradition Law — Principles and India's Practice
Key Principles of Extradition
| Principle | Description |
|---|---|
| Dual criminality | The alleged offence must be a crime in both the requesting and requested state |
| Specialty | The extradited person can only be tried for the offence for which extradition was granted |
| Non-extradition of political offenders | Political offences are generally excluded from extradition — though the definition of "political offence" varies |
| Rule of non-refoulement | A person cannot be extradited to a state where they face a real risk of torture or inhuman treatment |
| Double jeopardy | Extradition may be refused if the person has already been tried for the same offence |
India's Extradition Framework
| Feature | Detail |
|---|---|
| Governing law | Extradition Act, 1962 |
| Extradition treaties | India has extradition treaties with approximately 48 countries and extradition arrangements with 12 countries |
| Key treaty partners | UK, USA, Canada, UAE, France, Spain, Bangladesh, and others |
| Nodal ministry | Ministry of External Affairs (Consular, Passport & Visa Division) handles incoming and outgoing extradition requests |
| CBI role | Central Bureau of Investigation (CBI) and Interpol coordinate operational aspects |
High-Profile Extradition Cases
| Case | Status |
|---|---|
| Vijay Mallya | Former Kingfisher Airlines chairman; accused of defaulting on approximately Rs 9,000 crore in bank loans; fled to the UK in 2016; UK courts approved extradition in 2020 but actual transfer delayed due to legal challenges over prison conditions |
| Nirav Modi | Diamond merchant accused in the nearly USD 2 billion Punjab National Bank fraud; arrested in London in 2019; UK courts approved extradition in 2021; transfer delayed due to a "confidential impediment" cited by UK courts in 2025 |
| Abu Salem | Extradited from Portugal to India in 2005 under the condition that he would not be sentenced to death or imprisoned for more than 25 years — extradition conditions became a significant precedent |
| Ottavio Quattrocchi | Wanted in the Bofors scandal; India sought extradition from Argentina and Malaysia but was unsuccessful |
| Kim Davy (Niels Holck) | Purulia arms drop case (1995); India sought extradition from Denmark but the Danish High Court denied it in 2011 |
For Mains: India has faced persistent challenges in extraditing economic offenders from the UK. Prison conditions in India (particularly in Tihar Jail) have been cited as a reason for delays. In 2025, a CPS (Crown Prosecution Service) team from the UK visited Tihar Jail to assess conditions — a key step in addressing concerns. India enacted the Fugitive Economic Offenders Act, 2018 to allow confiscation of assets of fugitives who flee India to avoid prosecution.
Space Law
Major Space Law Treaties
| Treaty | Year | Key Provisions | India's Status |
|---|---|---|---|
| Outer Space Treaty | 1967 | Foundational treaty — space is free for exploration by all states; no sovereignty claims; no nuclear weapons in space; states responsible for national space activities | India is a party (ratified) |
| Rescue Agreement | 1968 | Return of astronauts and space objects to launching state | India is a party |
| Liability Convention | 1972 | Launching state is liable for damage caused by its space objects on Earth (absolute liability) and in space (fault-based liability) | India is a party |
| Registration Convention | 1975 | States must register space objects with the UN; maintains a register of objects launched into space | India is a party |
| Moon Agreement | 1979 | Declares the Moon and its resources as "common heritage of mankind"; restricts exploitation | India signed but has NOT ratified — the treaty has very few parties and no major spacefaring nation has ratified it |
Key Principles of the Outer Space Treaty (1967)
| Principle | Detail |
|---|---|
| Non-appropriation | Outer space, including the Moon and celestial bodies, is not subject to national appropriation by sovereignty claim, use, occupation, or any other means (Article II) |
| Freedom of exploration | Space shall be free for exploration and use by all states without discrimination (Article I) |
| Peaceful purposes | States shall not place nuclear weapons or WMDs in orbit or on celestial bodies (Article IV) |
| State responsibility | States are internationally responsible for national space activities, whether by governmental or non-governmental entities (Article VI) |
| Liability | Launching state is liable for damage caused by its space objects (Article VII) |
| Astronauts as envoys | Astronauts are regarded as "envoys of mankind" and must be assisted in case of accident or emergency (Article V) |
Artemis Accords
| Feature | Detail |
|---|---|
| Initiated by | United States (NASA), 2020 |
| Nature | Non-binding political commitment grounded in the Outer Space Treaty |
| Signatories | 61 countries as of January 2026 (including India) |
| Key principles | Peaceful purposes, transparency, interoperability, registration, release of scientific data, preservation of heritage, space resources, deconfliction of activities, orbital debris |
| India's signing | India signed the Artemis Accords during PM Modi's visit to the US in June 2023 |
| Controversy | Some nations (China, Russia) view the Accords as US-led effort to shape space governance outside the UN framework |
India's Space Law
India enacted the Indian Space Activities Bill (under development as of 2026) to regulate private sector participation in space activities. ISRO's commercial arm, NewSpace India Limited (NSIL), handles commercial launches and technology transfer. India's anti-satellite (ASAT) test in 2019 ("Mission Shakti") raised questions about space debris and the militarisation of space.
For Prelims: The Outer Space Treaty (1967) has 118 parties. India has signed but not ratified the Moon Agreement (1979). India signed the Artemis Accords in 2023. The treaty explicitly prohibits nuclear weapons in space but does not ban all military activities.
Antarctica Treaty System
Antarctic Treaty (1959)
| Feature | Detail |
|---|---|
| Signed | 1 December 1959, Washington D.C. |
| Entered into force | 23 June 1961 |
| Original signatories | 12 countries (Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, USSR, UK, USA) |
| Current parties | 56 states (29 Consultative Parties with decision-making power, 27 Non-Consultative Parties) |
| Key provisions | Antarctica used exclusively for peaceful purposes; freedom of scientific research; ban on military activities, nuclear explosions, and radioactive waste disposal |
India and Antarctica
| Milestone | Year | Detail |
|---|---|---|
| First expedition | 1981–82 | India's first Antarctic expedition launched under the Indian Antarctic Programme |
| Antarctic Treaty membership | 1983 | India became a Consultative Party, gaining decision-making power |
| Dakshin Gangotri | 1983 | India's first permanent research station, built on the ice shelf in Dronning Maud Land; decommissioned in 1990 after getting buried under snow |
| Maitri | 1989 | India's second station, located in the Schirmacher Oasis; currently operational |
| Bharati | 2012 | India's third station, operational since 18 March 2012; located in the Larsemann Hills |
| Maitri II | Planned by 2029 | New next-generation research station to replace the ageing Maitri station |
Protocol on Environmental Protection (Madrid Protocol, 1991)
The Protocol designates Antarctica as a "natural reserve devoted to peace and science" and bans mining and mineral resource activities (except for scientific research). The mining ban is subject to review after 2048, which has raised concerns about future resource exploitation pressures.
For Prelims: India has two active research stations in Antarctica — Maitri (1989) and Bharati (2012). Dakshin Gangotri (1983) was decommissioned. India became a Consultative Party to the Antarctic Treaty in 1983. A new Maitri II station is planned for completion by 2029.
Refugee Law and India's Position
International Framework
| Instrument | Year | Key Provision |
|---|---|---|
| 1951 Refugee Convention | 1951 | Defines "refugee" — a person who has a well-founded fear of persecution based on race, religion, nationality, membership of a particular social group, or political opinion |
| 1967 Protocol | 1967 | Removed geographic and temporal limitations of the 1951 Convention — made it universal |
| Principle of non-refoulement | Core principle | A refugee must not be returned to a country where they face serious threats to their life or freedom |
India's Position
| Aspect | Detail |
|---|---|
| Signatory status | India is NOT a signatory to either the 1951 Refugee Convention or its 1967 Protocol |
| Domestic law | India has no dedicated refugee legislation — refugees are treated as "foreigners" under the Foreigners Act, 1946 |
| Administrative approach | India handles refugees on an ad hoc, group-specific basis — Tibetans, Sri Lankan Tamils, and Bangladeshis have received varying levels of protection |
| UNHCR in India | UNHCR operates in India and issues refugee cards, but these have no legal standing under Indian law |
| Hosting record | Despite no legal framework, India hosts large refugee populations — Tibetans (since 1959), Sri Lankan Tamils, Chakma and Hajong refugees, Rohingya, and Afghans |
Citizenship Amendment Act (CAA), 2019
| Feature | Detail |
|---|---|
| Enacted | 12 December 2019 (rules notified in March 2024) |
| Provision | Provides accelerated pathway to Indian citizenship for persecuted religious minorities (Hindus, Sikhs, Buddhists, Jains, Parsis, Christians) from Afghanistan, Bangladesh, and Pakistan who entered India on or before 31 December 2014 |
| Excludes | Muslims from these three countries; does not cover refugees from other countries (e.g., Myanmar, Sri Lanka) |
| Controversy | Critics argue it discriminates on religious grounds; supporters say it targets specifically persecuted minorities in Muslim-majority countries |
| Important note | The CAA deliberately avoids the term "refugee" because India is not a signatory to the 1951 Convention and seeks to avoid associated obligations |
For Mains: India's approach to refugees is characterised by pragmatism rather than a legal framework. The absence of a domestic refugee law gives the government flexibility but also leaves refugees vulnerable to arbitrary decisions. The National Human Rights Commission has recommended that India enact a comprehensive national refugee law.
Diplomatic Immunity — Vienna Conventions
Vienna Convention on Diplomatic Relations (1961)
| Feature | Detail |
|---|---|
| Adopted | 18 April 1961 |
| Entered into force | 24 April 1964 |
| Parties | 193 states — virtually universal ratification |
| Purpose | Codifies the longstanding custom of diplomatic immunity and defines a framework for diplomatic relations between sovereign states |
Levels of Diplomatic Immunity
| Category | Immunity Level |
|---|---|
| Diplomatic agents (ambassadors, envoys) | Full immunity from criminal, civil, and administrative jurisdiction of the host state (Article 31) — can only be waived by the sending state |
| Family members | Same protections as the diplomatic agent (Article 37) |
| Administrative and technical staff | Immunity for acts performed in official capacity; criminal immunity is full but civil immunity is limited |
| Service staff | Immunity only for acts performed in the course of duties |
| Diplomatic premises | Inviolable — host state authorities may not enter without permission (Article 22); diplomatic bag cannot be opened or detained (Article 27) |
Vienna Convention on Consular Relations (1963)
| Feature | Detail |
|---|---|
| Adopted | 24 April 1963 |
| Key distinction | Consular officers have "functional immunity" (immunity for acts in exercise of consular functions) — not the broader "personal immunity" of diplomats |
| Article 36 | Right of consular access — if a national of one state is detained in another, the consular post must be informed "without delay" (this was the basis of the Jadhav case) |
For Prelims: The Vienna Convention on Diplomatic Relations (1961) and the Vienna Convention on Consular Relations (1963) are two separate treaties. Diplomatic immunity is broader (full personal immunity) while consular immunity is narrower (functional immunity only). Article 36 of the Consular Convention — the right of consular access — was central to the ICJ's Jadhav case judgment.
Key Terms for Quick Revision
| Term | Meaning |
|---|---|
| Jus cogens | Peremptory norms of international law from which no derogation is permitted (e.g., prohibition of genocide, slavery, torture) |
| Opinio juris | Belief that a practice is legally obligatory — required element for custom to become customary international law |
| Pacta sunt servanda | "Agreements must be kept" — the fundamental principle that treaties are binding on parties |
| Ratification | Formal act by which a state expresses its consent to be bound by a treaty (distinct from signing) |
| Reservation | A unilateral statement by a state at the time of ratification, modifying or excluding certain treaty provisions |
| Non-refoulement | Prohibition on returning a person to a country where they face persecution — cornerstone of refugee law |
| Complementarity | ICC principle — the Court acts only when national courts are unwilling or unable to prosecute |
| Innocent passage | Right of ships to pass through the territorial sea without prior notification, provided the passage is not prejudicial to peace, order, or security |
| EEZ | Exclusive Economic Zone — up to 200 nm from baseline, sovereign rights over resources but freedom of navigation for other states |
| Common heritage of mankind | Principle that certain areas (deep seabed, potentially space) belong to all humanity and cannot be appropriated by any state |
Recent Developments (2024–2026)
ICJ Advisory Opinion on Climate Change Obligations — December 2024
The International Court of Justice (ICJ) held public hearings in December 2024 on its advisory opinion regarding the obligations of states in respect of climate change, following a request by the UN General Assembly. This represents the first time the ICJ has been asked to opine on climate obligations under international law, with implications for loss-and-damage liability and state responsibility for emissions. Developing nations including Small Island Developing States (SIDS) presented arguments for stronger legal obligations on historical emitters.
India participated in the proceedings, emphasising common but differentiated responsibilities (CBDR) and the principle that developed nations bear greater historical responsibility. The advisory opinion, when issued, could reshape the legal landscape for climate litigation globally.
UPSC angle: The ICJ climate advisory opinion connects international law (GS-II) with climate diplomacy (GS-III). Key concepts: advisory opinion (non-binding but authoritative), CBDR principle, loss-and-damage.
India and the Indus Waters Treaty — Suspension as International Law Issue (2025)
India's decision on 23 April 2025 to put the Indus Waters Treaty (1960) "in abeyance" following the Pahalgam terrorist attack raised significant questions of international treaty law. India invoked Pakistan's material breach of bilateral obligations (cross-border terrorism) and changed circumstances (increased water needs) as grounds for suspension. Pakistan declared any interference with treaty-mandated water flows an "act of war."
The episode illustrates the doctrine of rebus sic stantibus (fundamental change of circumstances — Article 62, Vienna Convention on the Law of Treaties, 1969) and exceptio inadimpleti contractus (a party may suspend performance where the other party has materially breached) as invoked in bilateral treaty disputes. The World Bank, as a treaty guarantor, faced calls to intervene.
UPSC angle: A landmark case study for international treaty law. Links VCLT doctrines (rebus sic stantibus, pacta sunt servanda, material breach) to real-world India-Pakistan context. High Mains probability.
UNCLOS and South China Sea — Ongoing Relevance for India
China continues to reject the 2016 Permanent Court of Arbitration (PCA) ruling that found China's Nine-Dash Line claims incompatible with UNCLOS. India supports UNCLOS as the foundational framework for maritime law but has not ratified certain UNCLOS dispute resolution mechanisms (Part XI on deep seabed). India's own maritime security interests in the IOR are advanced through freedom-of-navigation principles enshrined in UNCLOS.
India's SAGAR (Security and Growth for All in the Region) doctrine explicitly references UNCLOS norms as the legal basis for its Indo-Pacific maritime approach — positioning India as a rule-based order champion against China's revisionist maritime claims.
UPSC angle: UNCLOS provisions (EEZ, territorial sea, contiguous zone, continental shelf distances) are high-frequency Prelims topics. India's UNCLOS stance vis-à-vis China is important for Mains on Indo-Pacific strategy.
ICC and International Justice — India's Position
India is not a member of the International Criminal Court (ICC) — having neither signed nor ratified the Rome Statute (1998). India's objections focus on the ICC's jurisdiction potentially being invoked against Indian security forces in conflict areas and the perceived political bias in ICC investigations. In 2024, the ICC issued an arrest warrant for Israeli PM Netanyahu, prompting debate about the limits of ICC jurisdiction and state cooperation. India maintained its standard position of non-membership while continuing to engage with UNODC and other UN crime-prevention bodies.
UPSC angle: India's non-membership of the ICC is a frequently tested Prelims fact. For Mains, contrast India's support for the International Court of Justice (ICJ) with its non-participation in the ICC.
Treaty on the Prohibition of Nuclear Weapons (TPNW) — India's Abstention
The TPNW (2017) entered into force in January 2021 and has continued to gain signatories, though all nine nuclear-armed states (including India) have not joined. India abstained at its First Meeting of States Parties (2022) and continues to advocate for a universal, non-discriminatory, and verifiable nuclear disarmament framework through the NPT process rather than the TPNW. India argues the TPNW does not address the security environment that necessitates nuclear deterrence.
UPSC angle: Links nuclear diplomacy (GS-II) with international law (NPT vs TPNW). India's stated preference for a phased, universal disarmament approach under the NPT framework is a recurring Mains theme.
Exam Strategy
For Mains Answer Writing: International law questions often appear in GS-II Paper 2 as part of "bilateral, regional and global groupings." When writing answers, always cite specific treaty provisions (e.g., "Article 36 of the Vienna Convention on Consular Relations" rather than just "Vienna Convention"). Use the Jadhav case, UNCLOS disputes, and ICC debates as contemporary examples. Structure answers around India's principled positions — sovereignty, non-interference, and multilateral frameworks through the UN.
For Prelims: Focus on numerical facts — maritime zone distances (12 nm territorial sea, 24 nm contiguous zone, 200 nm EEZ), number of ICC member states (124), number of Geneva Conventions (4 + 3 Additional Protocols), and India's ratification status for major treaties. The distinction between the two Vienna Conventions (1961 for diplomatic relations, 1963 for consular relations) is frequently tested.
