(1) Mandates shall be allocated to county lists proportionate to the votes cast, using the calculation method under section 17 (3).

(2) The following shall not receive mandate:

a) the county list of the nominating organisation if it did not reach five per cent of the valid votes cast for county lists, or

b) the joint county list if it did not reach ten per cent or, if the joint county list is drawn up by more than two nominating organisations, fifteen per cent of the valid votes cast for county lists. In this respect, only those valid votes can be aggregated that are cast for joint county lists drawn up by the same nominating organisations.

(3) If a list receives more mandates than the number of persons on the list, the mandate shall remain unfilled.
