Rectification by the Population Register Centre or a local register office 

If the Population Register Centre or a local register office considers that someone has been unlawfully omitted from or included in the voting register, or if a register entry concerning someone is erroneous, it has the right, by virtue of office, to add the person to the register, list him or her as ineligible to vote or correct the erroneous entry. Changes shall be made by 12.00 on the 12th day before the election day at the latest. 

When listing a person as ineligible to vote in the voting register, a written decision on this shall be issued and served on the person concerned in the manner provided in section 25, subsection 2.

However, no written decision shall be made if the person is deceased or has been pronounced dead after the establishment of the voting register.

When adding a person to the voting register, a polling card shall be sent to him or her without delay.

When correcting an erroneous entry in the register, the person concerned shall be notified of this without delay, unless this is manifestly unnecessary.

If the Population Register Centre has, before the voting register for elections to the European Parliament became legally valid, received a notice from an authority in another Member State of the European Union stating that a person listed as eligible to vote in the voting register has been listed in the electoral roll for the same elections in the said state, it shall without delay ensure that the person concerned is listed in the voting register as ineligible to vote.
