Commentaries: Art. 137

Supplementary elections take place if a vacant seat arises or a member is not re-elected.
If by the day before the elections the office the United Federal Assembly has not received more candidate nominations than there are vacant seats, a list of the names of the candidates in alphabetical order shall serve as the ballot paper, or a list without names but with the same number of lines as there are seats to be filled.
In the first two ballots, all those who are eligible for election may be elected. From the third ballot onwards no further candidatures are permitted.
Excluded from the election are:
1. those who obtain fewer than ten votes from the second ballot onwards; and
2. from the third ballot onwards, provided there are more candidates than vacant seats, the person who receives the lowest number of votes, unless more than one person receives this same number of votes.
