(1) Notwithstanding anything in the Representation of the People Act, 1948, a person shall not be entitled to vote as an elector at an election of a person to serve as a Member of the Parliament of the United Kingdom for a constituency in Northern Ireland unless he was resident in Northern Ireland during the whole of the period of three months ending on the qualifying date for that election.
(2) Subsection (2) of section two of the Representation of the People Act, 1948 (which specifies the cases where a person's residence is not to be deemed to be interrupted) and subsection (3) of that section (which provides that a person detained in a mental hospital or prison is not to be treated as resident there) shall apply for the purposes of the preceding subsection as they apply for the purposes of section one of that Act.
(3) The preceding provisions of this section shall not affect the right to vote of any service voter, and a person ceasing to have a service qualification shall be treated for the purposes of subsection (1) of this section as if he were resident in Northern Ireland during the period during which he had a service qualification.
(4) The register of parliamentary electors shall, for the purposes of Part I of the Representation of the People Act, 1948, be conclusive on the question whether or not a person registered as an elector in a constituency in Northern Ireland was resident in Northern Ireland during the whole of the period of three months ending on the qualifying date.
