The right of abode is a statutory right, which a person either has or does not have, depending on whether they meet the conditions in section 2 of the 1971 Act. Under s.2A of the 1971 Act, the right of abode can be taken away.

British citizens; and
Commonwealth citizens who had the right of abode before 1 January 1983 and who have not, since then, ceased to be Commonwealth citizens.
