The United Nations Convention on the Law of the Sea (UNCLOS), often referred to as the Constitution of the Oceans, is the primary international treaty governing the use and conservation of the world's oceans. Adopted in 1982, it establishes the legal framework for maritime zones, such as territorial waters, the Exclusive Economic Zone (EEZ), the continental shelf, and the high seas. UNCLOS plays a crucial role in regulating the rights and responsibilities of coastal states, landlocked countries, and the international community with respect to maritime navigation, resource extraction, and marine environmental protection.

What Is the Role of UNCLOS in Maritime Law?

Legal Framework for Maritime Zones

UNCLOS defines the various maritime zones that a coastal state can claim, such as the territorial sea, the Exclusive Economic Zone (EEZ), and the continental shelf. It also outlines the rights, responsibilities, and limitations of states within these zones:

  • Territorial Waters: Coastal states have sovereignty over their territorial waters, which extend up to 12 nautical miles from the baseline (usually the low-water line along the coast).
  • Exclusive Economic Zone (EEZ): Coastal states have sovereign rights over the resources in their EEZ, which can extend up to 200 nautical miles from the baseline.
  • Continental Shelf: UNCLOS defines the limits of the continental shelf, allowing states to claim sovereign rights to seabed resources up to 200 nautical miles or beyond, provided they can substantiate their claims scientifically.

Freedom of Navigation

UNCLOS guarantees freedom of navigation on the high seas, ensuring that all states have the right to navigate, overfly, and lay submarine cables and pipelines on the high seas and in areas not under the jurisdiction of any state. However, it also establishes rules for the innocent passage of ships through the territorial waters of other states and ensures that states respect the rights of other countries when navigating in exclusive economic zones (EEZs).

Rights Over Resources

UNCLOS plays a pivotal role in governing the exploration and exploitation of resources in the world's oceans:

  • Living Resources: Coastal states have the right to regulate fisheries within their EEZ to ensure sustainable fishing. UNCLOS promotes cooperation between countries to manage shared fish stocks.
  • Non-living Resources: Coastal states also have sovereign rights over the seabed and subsoil of the continental shelf, including resources such as oil, gas, and minerals. UNCLOS outlines the conditions under which states can explore and exploit these resources, with a focus on environmental conservation.

Marine Environmental Protection

UNCLOS provides legal mechanisms to protect the marine environment from pollution and degradation. It mandates coastal states to prevent and control marine pollution from land-based sources, ships, and dumping. Additionally, UNCLOS encourages states to cooperate on marine environmental issues and to take preventive measures to safeguard marine biodiversity.

  • Pollution Control: UNCLOS establishes frameworks for the regulation and monitoring of marine pollution, including from oil spills, plastic waste, and sewage disposal.
  • Conservation of Marine Biodiversity: UNCLOS calls for the protection of marine ecosystems and marine species and advocates for the sustainable management of ocean resources.

Dispute Resolution Mechanisms

One of the most important features of UNCLOS is its provisions for resolving maritime disputes. UNCLOS provides a framework for states to settle disagreements through peaceful means, either through diplomatic negotiations or by using judicial bodies:

  • International Tribunal for the Law of the Sea (ITLOS): A specialized court that adjudicates disputes related to UNCLOS.
  • International Court of Justice (ICJ): The ICJ can also resolve disputes related to maritime law.
  • Arbitration: States can choose arbitration under UNCLOS to resolve disputes regarding maritime boundaries, the continental shelf, or the use of ocean resources.

Legal Status of the High Seas

UNCLOS establishes the high seas as an area open to all states and outside the jurisdiction of any particular country. These areas are governed by the principles of freedom of navigation, fishing, and scientific research. However, UNCLOS imposes certain restrictions to ensure that activities on the high seas do not endanger the marine environment or endanger the interests of coastal states.

Settlement of Delimitations

UNCLOS provides clear rules for the delimitation of maritime boundaries between neighboring countries, including those concerning overlapping EEZs or continental shelves. If countries disagree on the boundaries, UNCLOS recommends equitable solutions, either through negotiations, arbitration, or international tribunals.

International Seabed Authority (ISA)

UNCLOS created the International Seabed Authority (ISA) to regulate the exploration and exploitation of the resources of the international seabed area, or the Area, which is located beyond national jurisdictions. The ISA is responsible for ensuring that seabed mining is conducted responsibly and that resources are distributed equitably among all nations.

Key Provisions of UNCLOS Relevant to Maritime Law

  • Article 87: Freedom of the high seas, including freedom of navigation, overflight, and the laying of submarine cables.
  • Article 56: Sovereign rights of coastal states in their EEZ, including the rights to explore and exploit natural resources.
  • Article 77: Coastal states' rights to the continental shelf, including natural resource exploitation.
  • Article 92: Prohibition of any foreign military vessels from using the territorial sea without permission.
  • Article 123: Encourages cooperation between states in shared maritime regions to regulate living and non-living resources.

Examples of UNCLOS in Practice

South China Sea Dispute

Several countries, including China, the Philippines, and Vietnam, have overlapping claims in the South China Sea. UNCLOS has provided a framework for these countries to address maritime boundary issues, although the disputes remain unresolved in some areas.

India and Bangladesh Maritime Boundary

India and Bangladesh resolved their maritime boundary dispute in the Bay of Bengal through the International Tribunal for the Law of the Sea (ITLOS) under the framework of UNCLOS, allowing both countries to access fishing grounds and oil reserves.

Legal Protections and Responsibilities

Sovereign Rights and Jurisdiction

Coastal states are required to exercise sovereign rights responsibly, especially concerning the use and protection of marine resources, while respecting the rights of other states, including freedom of navigation.

Environmental Protection

UNCLOS obligates states to prevent marine pollution and protect marine biodiversity, particularly when conducting activities like oil exploration or shipping.
