If a list which has obtained an absolute majority of the valid votes cast has been awarded a number of seats which is smaller than the absolute majority of the number of seats to be awarded, the list in question shall be awarded one additional seat. One seat awarded to the list which obtained a seat for the lowest average or the smallest remainder shall therefore be withheld. If two or more lists obtained a seat for an equally low average or an equally low remainder, the matter shall be decided by lot.
