Chapter 14

For each constituency, the permanent constituency seats shall be distributed proportionally between the parties that may participate in the distribution. The distribution is made through a comparative number being calculated for the parties on the basis of the election results in the constituency. The party that on each calculation receives the greatest comparative number will be allocated a seat.

The calculation shall be conducted by applying the adjusted odd-number method. This means that as long as a party has not yet been allocated any seat, the comparative number is calculated by dividing by 1.2 the party’s number of votes in the constituency. When a party has received a seat, a new comparative number is calculated by dividing by 3 the party’s number of votes. Thereafter the process is continued in the same way by dividing the party’s number of votes with the next highest odd number for each new seat allocated.
