Article 23 Effect of registers
In relation to an Assembly election the register of local government electors shall be for the purposes of this Part conclusive on the following questions—
whether or not a person registered in it was on the qualifying date resident at the address shown, and
whether or not that address is in any local government area or any particular part of a local government area.
Any entry in the register of local government electors, if it gives a date as that on which the person named will attain voting age, shall for any purpose of this Part relating to him as elector be conclusive that until the date given in the entry he is not of voting age or is entitled to be treated as an elector except for the purposes of an Assembly election at which the date fixed for the poll is that or a later date.
A person registered as a local government elector, or entered in the list of proxies, shall not be excluded from voting at an Assembly election on any of the grounds set out in paragraph (4); but this shall not prevent the rejection of the vote on a scrutiny, or affect his liability to any penalty for voting.
The grounds referred to in paragraph (3) are—
that he is not of voting age,
that he is not or, on the qualifying date or the date of his appointment (as the case may be), was not—
a Commonwealth citizen,
a citizen of the Republic of Ireland, or
a relevant citizen of the Union, or
that he is or, on the qualifying date or the date of his appointment (as the case may be) was, otherwise subject to any other legal incapacity to vote.
