§ Art. 10Alteration of the number of constituency seats

Alteration of the number of constituency seats.
After each election to the Althingi, the National Electoral Commission shall calculate
whether the number of voters on the electoral register behind each parliamentary seat,
including the adjustment seats under paragraph 2 of Article 9, amounts to half the number of
voters behind each parliamentary seat in any other constituency, based on the electoral
register in the election just held, cf. paragraph 5 of Article 31 of the Constitution. If this is the
case, the National Electoral Commission shall alter the number of constituency seats in the
constituencies so as to reduce this difference. However, such a change shall never exceed
what is necessary at any given time to meet the requirements of this provision in the
Constitution.
When making calculations under paragraph 1, the first consideration shall be the number of
parliamentary seats in the constituencies under paragraph 1 of Article 9. If the conditions of
paragraph 1 are met, one constituency seat shall be reallocated from the constituency with the
smallest number of voters behind each parliamentary seat to the constituency with the highest
number of voters behind each parliamentary seat. If that is not possible, one constituency seat
shall be reallocated from the constituency with the second smallest number of voters behind
each parliamentary seat to the constituency with the highest number of voters behind each
parliamentary seat. When this has been done, the number of voters behind each Member of
Parliament (MP) shall be calculated again based on this alteration, and constituency seats
shall be reallocated between constituencies as often as necessary until the proportion of voters
behind each parliamentary seat nowhere exceeds the limit specified in paragraph 1.
The National Electoral Commission shall publicise such alterations in the Government
Gazette as soon as they have been made.
The National Electoral Commission’s authorisation to alter the number of MPs in
constituencies under this Article shall nevertheless extend only to those constituency seats
that are in excess of the constitutionally prescribed minimum, cf. paragraph 3 of Article 31 of
the Constitution.
