Commentary on provisions of the Act Section 31: Persons prevented from obtaining British citizenship etc
This section sets out which people will not be eligible for British citizenship, British overseas territories citizenship, British overseas citizenship and British subject status because they have entered the UK, the Islands, or an overseas territory unlawfully. It defines who is an "ineligible person" and so will not be able to apply under the provisions of the 1981 Act specified in section 32 to 35.
	Subsection (3) provides that a person will not be eligible if they have ever met the four conditions in section 2 of the Act, Subject to the modification of the condition in section 2(3) which is to be read for the purposes of this section as if the reference there to the date the Act was passed was a reference to 7 March 2023.
	Subsections (4) to (7) allow references to the UK in this section to be read as references to the Islands and British overseas territories. British citizenship can be acquired through a connection with the Islands, in the same way as in the UK, and through birth in an overseas territory. There are parallel provisions for British overseas territories citizenship to be acquired through a connection with an overseas territory, and a person holding British overseas territories citizenship alone is able to register as a British citizen. References to immigration provisions in section 2 are therefore to be read as if they included immigration provisions in the Islands, and equivalent immigration provisions in the territories.
