Context:
Recent attacks on neutral merchant vessels carrying Indian seafarers in international waters have revived debates over the legality of targeting neutral commercial ships under International Maritime Law, International Humanitarian Law (IHL), and the UN Charter.
Recent attacks on neutral merchant vessels carrying Indian seafarers in international waters have revived debates over the legality of targeting neutral commercial ships under International Maritime Law, International Humanitarian Law (IHL), and the UN Charter.
🔹 What is the Issue?
Neutral merchant vessels enjoy legal protection under international law even during armed conflicts. Any attack on such vessels is lawful only under narrowly defined circumstances and must comply with the principles governing both the use of force (Jus ad Bellum) and conduct during hostilities (Jus in Bello).
🔹 Twin Legal Framework Governing Maritime Warfare
| Law of the Sea (UNCLOS) | Law of Naval Warfare (IHL) |
|---|---|
| • Governs maritime zones and navigation rights. • Guarantees Transit Passage through international straits. • Protects navigation of neutral commercial vessels. | • Regulates conduct during armed conflict at sea. • Based on Customary IHL, San Remo Manual (1994), and Helsinki Principles. • Protects civilian ships and limits lawful military targeting. |
🔹 Core Principles of International Humanitarian Law (IHL)
| Principle | Meaning |
|---|---|
| Distinction | Military objectives must be distinguished from civilian vessels. |
| Military Necessity | Force may be used only to achieve a legitimate military objective. |
| Proportionality | Civilian harm must not be excessive compared to anticipated military advantage. |
| Precaution | All feasible precautions must be taken to minimize civilian casualties. |
🔹 When Can Neutral Ships Be Lawfully Attacked?
A neutral merchant vessel loses its protected status only when it directly contributes to military operations, such as:
- Transporting contraband (arms, ammunition or military supplies).
- Knowingly violating a legally declared naval blockade.
- Refusing lawful visit and search or resisting capture.
- Acting as a military auxiliary by carrying intelligence, transmitting military communications or laying naval mines.
Note: Ordinary commercial cargo (including oil exports) does not automatically become a military objective merely because it generates revenue. The controversial "War-Sustaining Theory" lacks universal acceptance under customary international law.
🔹 Jus ad Bellum: Legality of Use of Force
| Provision | Legal Position |
|---|---|
| Article 2(4), UN Charter | Prohibits use of force against territorial integrity or political independence of any State. |
| Article 51 | Permits force only in individual or collective self-defence. |
| Article 42 | Allows military action authorized by the UN Security Council. |
🔹 India's Legal Options
- Diplomatic Protection: Raise formal claims for injuries and deaths of Indian seafarers.
- Demand Accountability: Seek disclosure of intelligence and operational justification behind the attack.
- State Responsibility: Claim compensation and reparations for loss of life and property.
- Independent Investigation: Support an impartial international fact-finding mechanism.
- Strengthen Maritime Diplomacy: Promote freedom of navigation and protection of neutral shipping through multilateral forums.
🔹 Significance for India
- Protects Indian seafarers working across global shipping routes.
- Safeguards India's energy security and maritime trade.
- Strengthens India's position as a responsible maritime power.
- Reinforces commitment to a rules-based international order.
- Supports freedom of navigation in strategic waterways such as the Strait of Hormuz.
🔹 Key International Instruments
- United Nations Convention on the Law of the Sea (UNCLOS), 1982
- UN Charter (Articles 2(4), 42 & 51)
- San Remo Manual on International Law Applicable to Armed Conflicts at Sea (1994)
- Customary International Humanitarian Law (IHL)
- Helsinki Principles (1998)

Conclusion:
International law recognizes the protection of neutral merchant vessels as a cornerstone of maritime order. Attacks on such ships are lawful only under exceptional circumstances and must satisfy stringent requirements under both the Law of Naval Warfare and the UN Charter. For India, ensuring accountability for attacks on neutral shipping is essential not only to protect its citizens and trade but also to uphold the principles of a rules-based maritime order.
