The resultant Green paper, "Who Do We Think We Are?", was published in 1980 and its threefold definition of nationality formed the basis for the Government's legislation. Originally the paper proposed just two categories of British nationality, British citizenship and British Overseas citizenship. However, the British Dependent Territory governments successfully lobbied for an additional category of nationality, which would cater for those with close connections to any of the British territories. Modification of jus soli The Act also modified the application of jus soli in British nationality. Prior to the Act coming into force, any person born in the United Kingdom or a colony (with limited exceptions such as children of diplomats and enemy aliens) was entitled to CUKC status. After the Act came into force, it was necessary for at least one parent of a United Kingdom-born child to be a British citizen, a British Dependent Territories citizen or "settled" in the United Kingdom or a colony (a permanent resident). Even following the coming into force of the Act, the vast majority of children born in the United Kingdom or colonies still acquire British nationality at birth. Special provisions are made for non-British UK born children to acquire British citizenship in certain circumstances. Relation to Immigration Act 1971 Under section 11(1) of the Act, a CUKC must have had the right of abode under the Immigration Act 1971, as it existed on 31 December 1982, to become a British citizen on 1 January 1983 automatically under the standard CUKC transition at commencement route of the Act. Section 39 of the Act then went on to modify the right of abode section of the 1971 measure, eliminating confusing wording as to whether right of abode could be obtained through a grandparent who was a CUKC from outside the UK. Other changes The Act made a variety of other changes to the law: Mothers as well as fathers were allowed to pass on British nationality to their children. The term Commonwealth citizen was used to replace British subject. Under the Act, the term British subject was restricted to certain persons holding British nationality through connections with British India or the Republic of Ireland before 1949. Right of Abode could no longer be acquired by non-British citizens. A limited number of Commonwealth citizens holding Right of Abode were allowed to retain it.
