Understanding International Law Governing Maritime Conflicts and Naval Engagements

The key trap is confusing the extent of sovereignty in different zones. In the Territorial Sea (up to 12 nautical miles), a state has full sovereignty, subject only to the right of innocent passage for foreign vessels. In the Exclusive Economic Zone (EEZ, up to 200 nautical miles), a state has sovereign rights primarily for exploring and exploiting natural resources, but not full sovereignty over the waters or airspace.

The most crucial is the adoption of the United Nations Convention on the Law of the Sea (UNCLOS) in 1982 and its entry into force in 1994. While the Geneva Conventions of 1949 are important for International Humanitarian Law (IHL) and naval warfare, UNCLOS is the foundational treaty for defining maritime zones and overall ocean governance.

Nautical miles are the standard unit for sea navigation and maritime law because they are based on the Earth's circumference (one nautical mile is approximately one minute of latitude). This makes them practical for charting and international consistency. The approximate conversion is 1 nautical mile ≈ 1.852 kilometers.

Disputes persist because countries often interpret UNCLOS provisions differently, especially concerning historical claims, the legal status of certain island features, and the precise delineation of Exclusive Economic Zones (EEZs) and territorial seas where claims overlap.

• •Conflicting interpretations of UNCLOS provisions by different states.
• •Historical claims that often predate the adoption of UNCLOS.
• •Strategic importance of disputed areas due to resources (oil, gas, fisheries) and critical trade routes.
• •Lack of a universally accepted and enforceable mechanism for UNCLOS rulings, especially when powerful states disregard them.

UNCLOS primarily establishes the legal framework for all ocean space, defining maritime zones and the rights and obligations of states in both peacetime and wartime. IHL, specifically the laws of naval warfare (like those derived from the Geneva Conventions), governs *how* naval conflicts are conducted, focusing on rules of engagement, targeting principles, and the protection of non-combatants and civilians once a conflict begins.

The right of innocent passage allows foreign ships to navigate through a state's territorial sea without entering internal waters or calling at a port, provided the passage is not prejudicial to the peace, good order, or security of the coastal state. It must be continuous and expeditious.

• •Passage must be continuous and expeditious, not stopping or anchoring except for force majeure or distress.
• •Foreign vessels must refrain from any threat or use of force against the coastal state.
• •Activities like intelligence gathering, fishing, research, or serious pollution are prohibited.
• •Submarines and other underwater vehicles are required to navigate on the surface and show their flag.

India, as a responsible signatory to UNCLOS, generally upholds its principles, advocating for freedom of navigation and overflight, which are crucial for global trade and its own strategic interests. Its approach balances protecting its Exclusive Economic Zone (EEZ) and vital sea lanes with respecting international norms and promoting a rules-based order.

• •Upholds freedom of navigation, vital for its extensive trade and energy imports.
• •Combats piracy in regions like the Gulf of Aden, often through international cooperation and deployment of naval assets.
• •Engages in bilateral and multilateral naval exercises to enhance interoperability and assert its presence within legal frameworks.
• •Supports peaceful resolution of maritime disputes as per UNCLOS mechanisms, while also securing its own legitimate claims.

UNCLOS provides the primary legal basis for states to combat piracy on the high seas. It defines piracy and, crucially, grants universal jurisdiction, meaning any state can seize a pirate ship or aircraft, arrest the persons, and try them in their national courts, regardless of their nationality or the place of the act.

• •UNCLOS Article 105 grants universal jurisdiction over piracy committed on the high seas or in an Exclusive Economic Zone (if authorized by the coastal state).
• •International cooperation through joint naval patrols, information sharing, and coordinated operations is essential for effective anti-piracy efforts.
• •India actively participates in anti-piracy operations, deploying its naval assets to safeguard its shipping interests and ensure safe passage for international maritime trade.

Despite the challenges posed by increasing maritime disputes and differing interpretations, UNCLOS remains the foundational and most comprehensive legal framework for ocean governance. While its implementation and enforcement face hurdles, particularly when powerful states disregard rulings, the core principles are widely accepted. Calls are more for stronger adherence, peaceful dispute resolution, and consistent application of its provisions rather than a complete overhaul of the treaty itself.

Major global players often leverage their interpretations of UNCLOS to assert influence and strategic advantage. This is evident in actions like 'freedom of navigation operations' (FONOPs) conducted by some powers in disputed waters to challenge what they perceive as excessive maritime claims, or in disputes over resource exploitation rights within Exclusive Economic Zones (EEZs). These actions can escalate tensions and lead to naval posturing, making UNCLOS a battleground for geopolitical competition.

• •Freedom of Navigation Operations (FONOPs) by some naval powers are used to challenge excessive maritime claims, often leading to diplomatic protests.
• •Disputes over resource exploitation rights in EEZs, particularly in energy-rich areas, fuel competition and strategic rivalries.
• •Naval presence and military exercises are deployed to demonstrate commitment to specific interpretations of UNCLOS or to challenge opposing views.
• •The 'rules-based international order', with UNCLOS as a cornerstone, is frequently invoked by states to justify their actions or condemn those of others.
