United Nations Convention on the Law of the Sea
The term United Nations Convention on Law of the Sea (UNCLOS, also called simply the Law of the Sea or LOS) refers to several United Nations events and one international treaty. The events the term refers to are the (First) United Nations Convention on Law of the Sea, the Second United Nations Convention on Law of the Sea, and the Third United Nations Convention on Law of the Sea. The treaty resulting from the Third United Nations Convention on Law of the Sea also bears the name United Nations Convention on Law of the Sea and is the most recent major development in international law governing the oceans. The treaty provided new universal legal controls for the management of marine resources and the control of pollution. Its Secretariat resides within the United Nations Division for Ocean Affairs and the Law of the Sea .
The LOS was needed due to the weakness of the older 'freedom of the seas' concept, dating from the 17th century: national rights were limited to a specified belt of water extending from a nation's coastlines, usually three nautical miles (5.6 km), from the 'cannon shot' rule. All water beyond national boundaries was considered international waters- free to all nations but belonging to none of them.
Into the 20th century many nations expressed a need to extend national claims: to include mineral resources, to protect fish stocks and to have the means to enforce pollution controls. This was recognized by the League of Nations and a conference was held in 1930 at The Hague, but did not result in any agreements. The first nation to undermine the 'freedom of the seas' was the United States, in 1945 President Truman unilaterally extended his nation's control to cover all the natural resources of their continental shelf. Other nations were quick to emulate the USA, in 1946-1950 Argentina, Chile, Peru and Ecuador all extended their sovereign rights to a 200 nautical mile (370 km) distance - so as to cover their Humboldt Current fishing grounds. Other nations extended their territorial seas to 12 nautical miles (22 km). By 1967 only twenty-five nations still used the old three nautical mile limit, sixty-six nations had set a twelve nautical mile territorial limit, and eight had set a two-hundred nautical mile limit.
The (First) United Nations Convention on Law of the Sea (UNCLOS I)
In 1956, the United Nations held its first Conference on the Law of the Sea (“UNCLOS I”) at Geneva, Switzerland. UNCLOS I resulted in four treaties concluded in 1958:
- The Convention on the Territorial Sea and Contiguous Zone
- The Convention on the Continental Shelf
- The Convention on the High Seas
- The Convention on Fishing and Conservation of Living Resources of the High Seas
Although UNCLOS I was considered a success, it left open the important issue of breadth of territorial waters.
The Second United Nations Convention on Law of the Sea (UNCLOS II)
The United Nations followed this in 1960 with its second Convention on the Law of the Sea (“UNCLOS II”). UNCLOS II did not result in any international agreements.
The Third United Nations Convention on Law of the Sea (UNCLOS III)
The issue of varying claims of territorial waters was raised in the UN in 1967 by Arvid Pardo and in 1973 the Third United Nations Conference on the Law of the Sea was convened in New York to write a new treaty covering the oceans. The convention lasted until 1982 and over 160 nations participated. The convention was conducted under a process of consensus rather than majority vote in an attempt to reduce the possibility of groups of nation-states dominating the negotiations. The convention came into force on November 14, 1994, one year after the sixtieth state, Guyana, signed it.
The convention introduced a number of provisions, the most significant issues covered were - setting limits; navigation; exclusive economic zones (EEZ); continental shelf jurisdiction; deep seabed mining; the exploitation regime; protection of the marine environment; scientific research; and settlement of disputes.
The convention set the limit of territorial waters to 12 nautical miles, in which area the controlling state is free to set laws, regulate any use and use any resource. Vessels were given the right of 'innocent passage' through any territorial waters, with strategic straits allowing the passage of military craft as 'transit passage', in that naval vessels are allowed to maintain postures that would be illegal in territorial waters. Beyond the 12 nautical mile limit there was a further 24 nautical mile limit, the 'contiguous zone', in which area a state could continue to enforce laws regarding activities such a smuggling or illegal immigration.
The exclusive economic zones (EEZ) extended the exploitation rights of coastal nations to 200 nautical miles from shore, covering all natural resources. The EEZ were introduced to halt the increasingly heated clashes over fishing rights, although oil was also becoming important. The success of an offshore oil platform in the Gulf of Mexico in 1947 was soon repeated elsewhere in the world, by 1970 it was technically feasible to operate in waters 4000 metres deep.
Aside from its provisions defining ocean boundaries, the convention establishes general obligations for safeguarding the marine environment and protecting freedom of scientific research on the high seas, and also creates an innovative legal regime for controlling mineral resource exploitation in deep seabed areas beyond national jurisdiction, through an International Seabed Authority.
