Invalid and valid ballot papers

An invalid ballot paper shall be the one that is not completed, on which the ordinal numbers in front of two or more electoral lists have been circled, as well as any other ballot paper that is completed in such a manner that it cannot be determined with certainty for which electoral list the voter has voted.

A valid ballot paper shall be the one with a circled number in front of the name of one electoral list, as well as a ballot that is completed in such a manner that it can be concluded with certainty for whom the voter has voted.
