AN OVERVIEW OF THE UNITED NATIONS CONVENTION ON THE LAW OF THE SEA





1.0 INTRODUCTION
The 1982 United Nations Convention on the Law of the Sea (UNCLOS) is one of the most important international treaties in contemporary international law. Its lengthy text, consisting of 320 articles plus 9 annexes, deals with a range of issues of vital economic importance to many States that had been left unregulated, or had been insufficiently regulated, in the previous 1958 Conventions on the Law of the Sea. Negotiations leading to its adoption lasted a marathon nine years (1973-1982), and its coming into force had to await another 12 years (November 1994), following its 60th ratification.[1] As the main Constitution of the ocean, it defines rights and responsibilities of member nations in their use of the world’s oceans, establishing guidelines for businesses, the environment and management of marine natural resources.

2.0 HISTORICAL BACKGROUND
Prior to 20th Century, the ocean was considered no-man’s land, left open for any state landlocked or otherwise to navigate and exploit it. This was on the basis of the doctrine ‘Freedom of the Sea’ propounded by Hugo Grotius and adopted as an official statement by most countries. The doctrine adopted in the early 17th century, limited national rights and jurisdiction over a narrow band  of water along a nations coast, the rest of the sea being free to all and belonging to none.
It was only a century later that the ‘cannon shot rule’ was adopted to determine how much of the adjacent ocean’s were under the jurisdiction of a nation.[2]

In the 18th century, this range was approximated as three nautical miles. For a long time these simple rules provided effective governance of the world’s oceans a fact attributed to slow pace of technology developments. However, this changed in the 19th century in particular mid-19th century and early 20th century. This is because of the advent of technological advancement that cut across the western world. The industrial revolution churned out new and powerful products. In the shipping industry not only did the ships become more powerful, but technology allowed humanity to exploit ocean resources that had never before being envisioned. For instance fishermen once limited to areas near their own coasts could stay at the sea for longer times capturing plenty fish all courtesy to new equipped vessels. Overtime being virtually unrestrained, fleets around the world travelled to unexploited virgin grounds.

The lack of constraint eventually resulted to depletion of fish stocks around the world without regard to the stability of the number of fish. In addition, evolving technologies enabled exploitation of previously inaccessible off-shore resources, most notably oil and also diamonds, gravel and precious metals. For instance in 1947, off-shore oil production in the Gulf of Mexico stood at less than a million tons. By 1954, production had grown close to 400 million tons.[3]

In order to protect local resources (biological or minerals) nations began expanding their claims of sovereignty beyond the traditional three-mile limit. For instance, U.S through the Truman Proclamation[4]  set a claim of sovereignty by US to the outer continental shelf and resources therein.[5] Argentina, in 1950, actively claimed a wider continental shelf as well as water column above it.  Ecuador, Chile and Peru were asserting rights over 200 mile zone etc.
  This led to the growing understanding of the weaknesses of that existing regime and that an immediate solution was only proper. This phase ushered subsequent 3 conferences ie the UNCLOS I, UNCLOS II, and UNCLOS III.
UNCLOS I
In recognition of the flaws of the current regime, the General Assembly adopted Resolution 1105 (XI). This resolution called for the convening of the UN Convention on the Law of the Sea held in Geneva 1858. The meeting produced;
ü  The Convention on the Territorial Sea and Contiguous Zones
ü  The Convention on the High Seas
ü  The Convention on Fishing and Conservation of the Living Resources of the High Seas.
ü  The Convention on the Continental Shelf.
ü  Optional Protocol of Signature concerning the compulsory settlement of disputes
Although a significant step, there were still many issues which were left unsettled.
UNCLOS II
In an attempt to deal with the unresolved issues left by UNCLOS I, the General Assembly convened UNCLOS II. The parties met in 1960 to deliberate on the breadth of the territorial seas and fishery limits. While the conference adopted two resolutions, the parties were unable to come to a consensus on the issues at hand.
UNCLOS III
The General Assembly upon call from Mr. ArvidPardo[6] the General Assembly adopted Resolution 2467 A (XXIII) and Resolution 2750 C (XXV) which created the Committee on the Peaceful Uses of the Sea-bed and the ocean floor beyond the limits of a national jurisdiction and called for the convening of the third law of the sea meeting to be held in 1973. The deliberations lasted for 9 years, saw the participation of 160 nations and concluded in 1982 with the UNCLOS. While UNCLOS was first signed in December 1982, the agreement did not come into force until November 1994, a period of 12 years. UNCLOS required 60 signatures for ratification and could only enter into force one year after the final nation had ratified or acceded to the treaty.[7]


3.0 SALIENT FEATURES OF THE UNITED NATIONS CONVENTION ON THE LAW              OF THE SEA
1) Divisions of Oceans and Seabed Areas
One of the most powerful features of the United Nations Convention on the Law of the Sea is that it settled the question of the extent of national sovereignty over the oceans and seabed. Parts II, V, VI, and VII of the Convention established the various regions of the oceans, who has sovereignty over each, and to what degree.

a) Baselines
The baseline is the boundary from which a nation may begin measurements to determine the portion of the adjacent oceans or continental shelf over which it may exercise sovereignty. Except in some special cases, the baseline is the low-water line along the coast.

Detailed explanations of how baselines are determined are provided in Articles 5-7 and 9-14. Special rules have also been established for determining the baselines of archipelagic nations[8]  in Article 47.

b) Internal Waters
Internal waters are those that are contained on the landward side of the baseline. These waters fall under the exclusive sovereignty of the nation in which they are contained.

c) Territorial Sea
Article 3 of United Nations Convention on the Law of the Sea declares that a nation may establish a territorial sea that extends up to 12 nautical miles from the baselines. Within the territorial sea, a nation has exclusive sovereignty over the water, seabed, and airspace.

The treaty establishes that all nations have the right of innocent passage through the territorial sea of another nation and that, outside certain conditions, the nation laying claim to the territorial sea cannot hamper innocent passage of a foreign vessel. United Nations Convention on the Law of the Sea adopted the basic concepts of the territorial sea and the right of innocent passage that had been codified in the Convention on the Territorial Sea and the Contiguous Zone. However, it went a step further by establishing the limits of a nation's territorial sea.

By the late 1960's many nations recognized a 12-mile limit to the territorial sea. At the start of the UNCLOS, only twenty-five nations maintained the traditional claim of 3 nautical miles. Sixty-six nations were claiming 12 nautical miles, fifteen nations claimed between 4 and 10 nautical miles, and eight nations were claiming an astounding 200 nautical miles. Smaller nations, including those without large navies or merchant fleets, favored a larger territorial sea in order to protect their coastal waters from infringements by more powerful nations. The world's major naval and maritime powers, however, pressed for the 3-mile rule because the 12-mile rule would have placed over 100 straits used for international navigation under the exclusive sovereignty of other nations. Some of these included the Strait of Gibraltar[9], the Strait of Hormuz[10], and the Strait of Malacca[11].

Due to the ongoing Cold War during the Convention, smaller nations were concerned about the possibility of threats to their national security posed by warships of foreign nations or even the possibility of becoming embroiled in the conflicts of foreign powers. In an attempted compromise, the small nations offered the larger maritime powers the right of innocent passage, however, the maritime powers were not satisfied with this offer. The problem, in the view of the great powers, was that restrictions to innocent passage would prohibit covert or underground movements of vessels such as submarines and did not guarantee overflight rights, thereby creating a security risk.

Ultimately, the parties came together to form a compromise known as "transit passage." Applied specifically to straits that would otherwise fall within the territorial sea of a nation, transit passage applies to straits used for international navigation between one part of the high seas to another and allows for "navigation and overflight solely for the purpose of continuous and expeditious transit of a strait...." In all other ways aside transit passage, the waters of a strait still remain the territorial sea of the adjacent nation.

d) Contiguous Zone
The Contiguous Zone is a region of the seas measured from the baseline to a distance of 24 nautical miles. Within this region, a nation may exercise the control necessary to prevent the infringement of its customs, fiscal, immigration or sanitary laws and regulations within its territory or territorial sea, and punish infringement of those laws and regulations committed within its territory or territorial sea.

e) Exclusive Economic Zone
The Exclusive Economic Zone or "EEZ" is a region that stretches a distance of no more than 200 nautical miles from a nation's baselines. Generally, the rules regarding the High Seas, set forth in Articles 88 to 115, apply to the EEZ. Within its EEZ, a nation may explore or exploit the natural resources (both living and inanimate) found both in the water and on the seabed, may utilize the natural resources of the area for the production of energy (including wind and wave/current), may establish artificial islands, conduct marine scientific research, pass laws for the preservation and protection of the marine environment, and regulate fishing.

One of the primary purposes behind establishing the EEZ was to clarify the rights of individual nations to control the fish harvests off their shores[12].

The creation of the EEZ gave coastal nations jurisdiction of approximately 38 million square nautical miles of ocean space. The world's EEZs are estimated to contain about 87% of all of the known and estimated hydrocarbon reserves as well as almost all offshore mineral resources. In addition, the EEZs contain almost 99% of the world's fisheries, which allows nations to work to conserve the oceans vital and limited living resources.

f) Continental Shelf
Unlike the other maritime divisions, the continental shelf is a real, naturally-occurring geological formation. It is a gently sloping undersea plain between the above-water portion of a landmass and the deep ocean. The continental shelf extends to what is known as the continental slope, a point at which the land descends further and marks the beginning of the ocean itself. It is host to most of the world's oceanic plant and animal life and plays a vital role in energy production, from offshore oil and gas reserves to renewable energy resources.

When UNCLOS refers to the continental shelf, however, it is using "continental shelf" as a legal term. While the EEZ captures a lot of the continental shelf for many countries, it does not capture all of it. As such, UNCLOS includes provisions for nations to lay claim to a continental shelf that exceeds 200 nautical miles from the baseline by establishing the foot of the continental slope as set forth in Article 76, paragraphs 4-7. These provisions allow for an extension of an additional 150 nautical miles from the baseline or 100 miles from the 2,500 meter depth. Nations exercise over the shelf the sovereign right to explore and exploit the non-living natural resources of the continental shelf as well as the living organisms that live on the seabed itself. The water above the portion of the continental shelf that is not contained within the EEZ remains part of the high seas as does the airspace above that area. Nations wishing to request an extension of sovereignty over an extended portion of their naturally occurring continental shelf must do so within 10 years of UNCLOS coming into force for that particular nation.

The extension of sovereignty to the extended continental shelf comes with a price. A nation that exploits resources on the continental shelf beyond the 200 nautical mile mark is allowed five years in which to develop and exploit the resources of the shelf without charge. Starting on the sixth year, a nation has to pay 1 percent of the value of the resources produced from the site. The rate of payments increase by 1 percent for each year until the twelfth year and is capped at 7 percent thereafter. Developing nations are exempted from this provision. Revenues generated from these operations are deposited with the International Seabed Authority and equally distributed among national parties to UNCLOS.

g) High Seas
Waters beyond a nation's EEZ are considered to be the high seas. The high seas are still governed the "freedom of the seas" concept. No nation my lay claim to any portion of the high seas. The high seas are open to all States, whether coastal or land-locked. On the high seas, nations are permitted freedom of navigation and overflight, freedom to lay submarine cables and pipelines, freedom to construct artificial islands, freedom of fishing, and freedom of scientific research. The Convention makes provisions which prohibit the transport of slaves, piracy, illegal drug trafficking, and the suppression of unauthorized radio or television broadcasting on the high seas.

h) The Area
The "Area" is the seabed and ocean floor that is beyond the limits of national jurisdiction. This is the portion of the seabed that is beyond the EEZ or the recognized continental shelf of a country. It would be inaccurate to say that the Area is the seabed underneath the high seas, since the high seas can overlap portions of continental shelf that are subject to national sovereignty. The Area is particularly unique in that UNCLOS designates it and the resources it contains as "the common heritage of mankind." No nation is allowed to lay claim to any part of the Area or its resources. Regarding the resources, " all rights in the resources of the Area are vested in mankind as a whole...." As a result, companies that wish to exploit the mineral resources of the Area will have to enter into a profit sharing agreement in which the profits derived from mineral resources captured in the Area will be shared with developing nations.

2) Creation of Agencies by the United Nations Convention on the Law of the Sea.
In order to ensure the effective administration of the United Nations Convention on the Law of the Sea, the treaty created four bodies to handle specific issues:

a)      Commission on the Limits of the Continental Shelf
The Commission on the Limits of the Continental Shelf was created to implement Article 76 of the treaty. Article 76 allows for a nation to extend sovereignty over a portion of the continental shelf beyond the limits of the EEZ. The Commission is comprised of 21 members who are specialists in the fields of geology, geophysics, or hydrography and are elected by the Nations Parties to the Convention. Members of the Commission are charged with evaluating data submitted by a coastal nation requesting an extension of sovereignty over an extended portion of their naturally occurring continental shelf. The Commission was established and derives its authority from Annex II of the Convention.

b)      International Seabed Authority
The International Seabed Authority is the organization that is responsible for the governance of the Area. Article 156 of the Convention mandates the creation of the Seabed Authority. All nations that have agreed to be bound by UNCLOS are automatically members of the Authority. The Authority is comprised of three bodies: the Assembly, the Council, and the Secretariat.

i)                    The Assembly
The Assembly acts as a legislative organ in which each member nation has one representative. The Assembly is vested with, among others, the power to decide how revenues derived from deep seabed mining will be distributed and the power to set policy regarding activities in the Area and oversight of its management.

ii)                  The Council
The Council is a body comprised of 36 persons who represent various members of the Authority itself (the nations bound by the treaty). Members of the Council are elected by the Assembly and serve for a term of four years. The Council acts as the executive branch of the Authority and has the power of establishing the specific policies to be pursued by the Authority. Other powers of the Council include establishing subsidiary agencies, as may be necessary, to carry out the functions of the Council, approve or reject work plans related to the Area, oversee the collection of payments made to the Authority, and institute proceedings against a member nation in the Seabed Disputes Chamber.

Within the Council there are two Commissions: the Economic Planning Commission and the Legal and Technical Commission. Each Commission is comprised of members elected by the Council from a list of candidates nominated by the nations that are bound by UNCLOS. Members of either Commission serve for a term of five years and must have no personal financial connections related to exploration or exploitation of resources within the Area.

Members of the Economic Planning Commission are required to have qualifications in the areas of mining, management of mineral resources, international trade, or international economics and it is required that at least two members of the Commission are from developing nations whose mineral exports be the same as those being mined from the seabed. The primary function of the Economic Planning Commission is to expound upon the relationship between the minerals being mined, the effect mining has on global prices for the mineral in question, and the effect changes in price may have on developing nations.

Members of the Legal and Technical Commission are required to have qualifications in the areas of exploration, exploitation, and processing of mineral resources, oceanology, protection of the marine environment, or either economic or legal matters relating to the ocean mining industry. It is the responsibility of the Commission to review written plans for work activities to be conducted in the Area, prepare assessments of the environmental implications of activities in the Area, make recommendations to the Council regarding environmental protection of the Area, and to calculate the production ceiling and issue production authorization on behalf of the Authority.

iii)                The Secretariat
The Secretariat of the Authority is comprised of the Secretary-General and his or her staff. The Secretary General is elected for a term of four years. Nominations for Secretary-General are made by the Council and voted on by the Assembly. The Secretary-General serves as the chief administrative officer of the Authority and is required to make an annual report to the Assembly on the work of the Authority.

c)      The Enterprise
Article 170 calls for the formation of an agency called "the Enterprise." The purpose of the Enterprise is to coordinate the exploration and exploitation of resources in the area. Annex IV of the treaty details the composition and governance of the Enterprise, however, since deep seabed mining has yet to start, the Enterprise has never been called into action.

d)      International Tribunal for the Law of the Sea
Annex VI of UNCLOS establishes the International Tribunal for the Law of the Sea[13]. It is a permanent international court with expertise in law of the sea matters that sits in Hamburg, with a Statute closely resembling that of the ICJ in The Hague. It came into operation on 1st October 1996. It has jurisdiction over all disputes and applications submitted to it in accordance with the Convention and all matters specifically provided for in any other agreement which confers jurisdiction on it. The Tribunal is open to States Parties, and in certain circumstances, to entities other than States.

The Tribunal is comprised of 21 members, no two of which may be from the same member nation. Members of the Tribunal serve for a period of nine years, after which they are eligible for re-election to the Tribunal. The Tribunal has formed a number of Chambers including the Chamber of Summary Procedure, the Chamber for Fisheries Disputed, the Chamber for Marine Environment Disputes, and the Chamber for Maritime Delimitation Disputes. The Tribunal is also the home of the Seabed Disputes Chamber, which is responsible for adjudicating disputes pursuant to Part XI, Section 5 of UNCLOS, which governs settlements of disputes that arise from deep seabed activities.

4.0 CRITICISMS AND WEAKNESSES OF THE UNITED NATIONS CONVENTION ON THE LAW OF THE SEA
The Convention places so much reliance on national legislation to implement its provisions. This is a weakness on the part of the Convention because nations may not view such legislation as priority.

The Convention is also criticized and seen as weak for relying on national administration by the contracting parties. Some countries have shown a willingness to excuse violations that have happened abroad. Likewise, not all states prioritize conservation of marine resources and therefore little emphasis has been given to development of effective legislation in this area. This has led to weak national enforcement and regulation. Consequently, this has led to the emergence of ‘flags of convenience’ nations.

The Convention has also been criticized in that the jurisdictional breakdown of sovereignty as per the maritime zones does not take care of the natural order of the marine ecosystem. For instance, provisions of the Treaty that govern protection of fish stocks do not take into account the totality of ecosystems where such species thrive (e.g. the breeding areas and migratory patterns and routes of stocks), but rather focus on the territorial jurisdiction of the areas where these fish are to be found. The unfortunate outcome of this approach is that different parts of the fish stock’s ecosystem will fall under different territories of coastal states and therefore in the absence of application of uniform conservation measures, the protection goals of the Treaty may not be easily realized. This has been seen to hamper the cohesive management of marine resources.

Profit sharing provisions related to deep seabed mining have similarly been criticized as being contradictory to free-market capitalism practices i.e. any country with capacity should have the freedom to mine the seabed without unnecessary fetters. However, this criticism seems misplaced if placed in the context of environmental conservation and preservation. The requirement of profit sharing may be depicted as a tool for environmental conservation as it acts as a bar for states which are unwilling to share profits from exploiting the minerals in the deep seabed. It also appears economical in that the fact that the profits of mining are shared with the developing countries acts as a booster for the economy of the developing countries, who actually may not even be equipped with the necessary technology to engage in such mining activities.

Explosion of piracy cases off Somalia’s coast is also viewed as a manifestation of a critical weakness in UNCLOS. The treaty did not anticipate inability of a State to protect its coastal waters as a result of state collapse and failure as it happened in Somalia. Likewise, the treaty did not contemplate acts of piracy occurring within the territorial waters of a state (e.g. within Somalia’s coastline. Such acts are therefore difficult to criminalize and punish in the absence of a government (e.g. in the case of Somalia). This perhaps explains why prosecution of Somali piracy cases in Kenya have hit perennial legal snags.


5.0 CONCLUSION
Despite the weaknesses and critics lodged against the United Nations Convention on the Law of the Sea, the significance of the treaty in the regulation, conservation and preservation of the oceans and seas is unmatched. This is clearly visible from the features which mark the treaty and the provisions of the treaty which have taken aboard environmental considerations with regard to  the use, exploration and exploitation of the marine resources.

[7]The reason why many nations why many nations took so long to sign the treaty is because of Article 309 which prohibits nations from taking out reservations to any part of the treaty. A reservation is a statement made by a nation when accepting a treaty, whereby it excludes or modifies the legal effect of certain provisions of a treaty as those terms apply to the nation accepting the treaty. The inability of a nation to take out reservations to particular terms of treaty caused many nations to hesitate.
