15288-502: The coastal state's rights below the surface of the sea. The surface waters are international waters . Generally, a state's exclusive economic zone is an area beyond and adjacent to the territorial sea, extending seaward to a distance of no more than 200 nmi (370 km) out from its coastal baseline . The exception to this rule occurs when exclusive economic zones would overlap; that is, state coastal baselines are less than 400 nmi (741 km) apart. When an overlap occurs, it

15444-627: The conservation of Chagos, and global biodiversity. In February and March 2013, a research expedition was undertaken in the Chagos Marine Protected Area (MPA).

16068-713: The development of self-governance, and the First Great Awakening , a series of Christian revivals , fueled colonial interest in religious liberty . For a century, the American colonists had been providing their own troops and materiel in conflicts with indigenous peoples allied with Britain's colonial rivals , especially France, and the Americans had begun to develop a sense of self-defense and self-reliance separate from Britain. The French and Indian War (1754–1763) took on new significance for all North American colonists after Parliament under William Pitt

16224-482: The dispossession of native inhabitants .

[the government] sought 'no constraints on military operations' as a result of the establishment of a marine park." An exemption in the MPA allows people from the US base on Diego Garcia to continue fishing. In 2010, more than 28 tonnes of fish was caught for use by personnel on

16848-419: The exclusive economic zones includes the contiguous zone . States also have rights to the seabed of what is called the extended continental shelf up to 350 nmi (648 km) from the coastal baseline, beyond the exclusive economic zones, but such areas are not part of their exclusive economic zones. The legal definition of the continental shelf does not correspond exactly to the geological meaning of

17004-541: The federal government often applied policies of Indian removal or assimilation . The Trail of Tears (1830–1850) was a U.S. government policy that forcibly removed and displaced most Native Americans living east of the Mississippi River to lands far to the west.

18096-479: The largest aircraft in the US Air Force . The Chagossians say they would in effect be barred from ever returning because the marine protection zone would stop them fishing, their main livelihood. "There would be a natural injustice. The fish would have more rights than us, the conservation groups have fallen into a trap. They are being used by the government to prevent us returning," said Roch Evenor, secretary of

18252-420: The last figure indicates China's claimed boundaries, and does not take into account adjacent powers' claims. Croatia proclaimed Ecological and Fisheries Protection Zone in 2003, but it was not enforced toward other European Union states especially Italy and Slovenia. The zone was upgraded to EEZ in 2021 together with Italy and Slovenia. Territorial waters has 18,981 km , while internal waters located within

18408-576: The legality of the marine protected area. Mauritius considers that the UK, not being a "coastal State" under UNCLOS and international law, had no authority to purport to establish a marine protected area around the Chagos Archipelago and that the MPA was not compatible with the rights of the Chagossians . The original Chagossians were deported from the largest island, Diego Garcia, 40 years earlier to make way for Naval Support Facility Diego Garcia , with port facilities and an airstrip capable of handling

18564-564: The limits of Australia's EEZ. Australia also claimed, in its submission to the UN Commission on the Limits of the Continental Shelf, additional Continental Shelf past its EEZ from the Australian Antarctic Territory , but these claims were deferred on Australia's request. However, Australia's EEZ from its Antarctic Territory is approximately 2 million square kilometres. Brazil 's EEZ includes areas around

18720-488: The marine reserve. In the final months leading up to the designation, the Bertarelli Foundation offered to fill the funding gap left by the absence of fisheries income and thereby contribute to the costs of an enforcement boat for a period of five years.

20280-574: The primary colonial grievances was a denial of their rights as Englishmen , particularly the right to representation in the British government that taxed them . To demonstrate their dissatisfaction and resolve, the First Continental Congress met in 1774 and passed the Continental Association , a colonial boycott of British goods that proved effective. The British attempt to then disarm the colonists resulted in

20436-434: The reserve to restrict fishing would be the "most effective long-term way to prevent any of the Chagos Islands' former inhabitants or their descendants from resettling." The same cable explained that the protection would permit environmental damage if caused by military use: "the terms of reference for the establishment of a marine park would clearly state that the BIOT, including Diego Garcia, was reserved for military uses. ...

20592-415: The reserve's boundaries. The marine reserve is an important refuge for overfished pelagic species such as manta rays , sharks including whale sharks , tuna and is of particular importance for globally threatened species, such as the silky shark .

21216-771: The ruling as an important milestone in the relentless struggle, at the political, diplomatic and other levels, of successive Governments over the years for the effective exercise by Mauritius of its sovereignty over the Chagos Archipelago. The tribunal considered in detail the undertakings given by the United Kingdom to the Mauritian Ministers at the Lancaster House talks in September 1965. The UK had argued that those undertakings were not binding and had no status in international law. The Tribunal firmly rejected that argument, holding that those undertakings became
