International Law on Naval Warfare: Legality of Attacks on Neutral Ships and India's Rights

This article analyzes the legality of attacks on neutral merchant vessels under international law, prompted by recent U.S. Navy strikes on tankers with Indian seafarers. It explains that naval operations are governed by the 'law of naval warfare' (IHL) and the 'law of the sea' (UNCLOS). While neutral ships are generally protected, this status can be lost if they contribute to military action or breach a lawful blockade. The article questions the legality of the U.S. strikes, particularly concerning whether the blockade itself was lawful under the UN Charter's prohibition on the use of force. It concludes by outlining India's right to seek explanations, accountability, and compensation for its citizens' injuries under diplomatic protection.

Key Points

  • Naval operations during armed conflict are governed by the 'law of naval warfare' (IHL) and the 'law of the sea' (UNCLOS).
  • Neutral merchant vessels and civilians are generally protected, but this protection can be lost if they effectively contribute to military action or breach a lawful blockade.
  • The legality of attacking oil tankers depends on whether they qualify as 'military objectives' and contribute directly to military efforts.
  • The article questions the lawfulness of blockades not authorized by the UN Security Council under the UN Charter's prohibition on the use of force.
  • India has the right to seek explanations, accountability, and compensation for its citizens affected by such incidents under diplomatic protection.

Exam Facts

  • The two primary bodies of law governing naval operations are the 'law of naval warfare' (IHL) and the 'law of the sea' (UNCLOS).
  • UNCLOS (United Nations Convention on the Law of the Sea) is often called the 'Constitution of the Oceans'.
  • Article 2(4) of the UN Charter prohibits states from using force against another State's 'territorial integrity' or 'political independence' without UN Security Council authorization or self-defence.
  • The San Remo Manual on International Law Applicable to Armed Conflicts at Sea (1994) and the Helsinki Principles on the Law of Maritime Neutrality (1998) are key documents.
