Associated state

The concept of associated state was originally used to refer to arrangements under which Western powers afforded a (sometimes very limited) degree of self-government to some of their colonial possessions after the end of World War II. Soon after the conclusion of the war, the French colonial territories of Vietnam, Cambodia, and Laos were designated as 'associated states' within the newly created French Union. The arrangement afforded these countries a limited degree of internal and external sovereignty (for example, they were allowed to enter into diplomatic relations with a small number of countries), but for the most part reserved for France effective control over foreign relations, as well as military, judicial, administrative, and economic activities.[3][4] According to some French jurists, the concept of associated state under the 1946 French constitution automatically extended to the territories of Morocco and Tunisia, which up until then had been protectorates of France. However, unlike their counterparts in Southeast Asia, neither Morocco nor Tunisia became part of the French Union.[5] The associated state concept as applied to former French colonial possessions has been described as 'neo-colonial' as it did not afford them real internal or external sovereignty.[3] All of the aforementioned associated states eventually became fully independent states.

Puerto Rico is defined as an "associated free state" (Estado Libre Asociado) in its 1952 constitution. However, it remains a territory of the United States. While exercising substantial internal self-government, Puerto Rico is subordinated to the U.S. Constitution in areas such as foreign affairs or defense. For this reason, it is not considered to be a full-fledged associated state under either international or U.S. domestic law.[6][7]

The Cook Islands and Niue have the status of "self-government in free association".[8] New Zealand cannot legislate for them,[9][10] and in some situations they are considered sovereign states.[11] In foreign relations both interact as sovereign states,[12][13] and they have been allowed to sign on as a state to United Nations treaties and bodies.[12][14] New Zealand does not consider them to be constitutionally sovereign states due to their continued use of New Zealand citizenship.[8][15] Both have established their own nationality and immigration regimes.[16]

The Federated States of Micronesia (since 1986), the Marshall Islands (since 1986), and Palau (since 1994) are associated with the United States under what is known as the Compact of Free Association, giving the states international sovereignty and ultimate control over their territory. However, the governments of those areas have agreed to allow the United States to provide defense; the U.S. federal government fund grants and access to U.S. social services for citizens of these areas. The United States benefits from its ability to use the islands as strategic military bases.

A formal association existed under the Associated Statehood Act 1967 between the United Kingdom and the six West Indies Associated States. These were former British colonies in the Caribbean: Antigua (1967–1981), Dominica (1967–1978), Grenada (1967–1974), Saint Christopher-Nevis-Anguilla (1967–1983), Saint Lucia (1967–1979), and Saint Vincent (1969–1979). Under this arrangement, each state had internal self-government, but the UK retained responsibility for foreign relations and defence.[25] The United Nations never determined whether these associated states had achieved a full measure of self-government within the meaning of the United Nations Charter and General Assembly resolutions. Within a few years after the status of associated state was created, all six of the former associated states requested and were granted full independence, except for Anguilla within the former St. Kitts-Nevis-Anguilla union, which separated from the associated state before independence and remains a United Kingdom dependent territory.

Shortly before the dissolution of the Soviet Union, the autonomous Soviet republic of Tatarstan declared itself a "sovereign state" and a "subject of international law". Tatarstan and the recently formed Russian Federation entered into a treaty in 1994 specifying that Tatarstan was "associated" with the latter (rather than being an integral part of it). Through the agreement Tatarstan delegated certain powers (such as some foreign relations and defense) to Russia. Changes made to Tatarstan's constitution in 2002 have been seen by some commentators as fundamentally changing this relationship, with Tatarstan now functioning as essentially an integral part of Russia.[26][27][28][29][30]

In 2003, then-Basque Country president Juan José Ibarretxe proposed to the Spanish Congress a reform that would have transformed the region from an autonomous community within Spain into a state in free association, therefore making Spain into a confederal state.The proposal was overwhermingly rejected by the Congress.[31][32][33]

Tokelau (a dependent territory of New Zealand) voted on a referendum in February 2006 to determine whether it wanted to remain a New Zealand territory or become the third state in free association with New Zealand (after the Cook Islands and Niue). While a majority of voters chose free association, the vote did not meet the two-thirds threshold needed for approval. A repeat referendum in October 2007 under United Nations supervision yielded similar results, with the proposed free association falling 16 votes short of approval.[34]

According to statements of officials of Abkhazia and Transnistria (self-proclaimed partially recognized republics seceded from the former USSR's constitutive republics of Georgia and Moldova respectively), both intend after recognition of their independence to become associated states of the Russian Federation. In Transnistria a referendum took place in September 2006, in which secession from Moldova and "future free association" with Russia was approved by a margin of 97%, even though the results of the referendum were internationally unrecognized.

The government of the United States unincorporated territory of Guam, led by then-Governor Eddie Calvo, started campaigning in early 2011 for a plebiscite on Guam's future political status, with free association following the model of the Marshall Islands, Micronesia, and Palau as one of the possible options.[35][36] The plebiscite, however, only allowed "native inhabitants" as defined under Guam law to register for it. A white, non-Chamorro resident, Arnold Davis, filed a federal lawsuit in 2011 for being denied registration for the plebiscite and a July 2019 ruling by the United States Court of Appeals for the Ninth Circuit ultimately blocked the plebiscite on the basis that the law was race-based and violated constitutionally protected voting rights; the United States Supreme Court declined to hear the Government of Guam's appeal in May 2020.[37][38]

Other situations exist where one state has power over another political unit. A dependent territory is an example of this, where an area has its own political system and often internal self-government, but does not have overall sovereignty. In a loose form of association, some sovereign states cede some power to other states, often in terms of foreign affairs and defense.

The existence of free relationship based on both delegation of sovereignty and benign protection can be seen as a defining feature of microstates. According to the definition of microstates proposed by Dumienski (2014): "Microstates are modern protected states, i.e. sovereign states that have been able to unilaterally depute certain attributes of sovereignty to larger powers in exchange for benign protection of their political and economic viability against their geographic or demographic constraints."[2] Adopting this approach permits separating microstates from both small states and autonomies or dependencies. Microstates understood as modern protected states include such states as Liechtenstein, San Marino, Monaco, Vatican City, Andorra, Niue, the Cook Islands, and Palau.
