Where a question may be divided into more than one part, each part may, on request, be voted on separately.
If two proposals in respect of the same subject matter have been submitted and they either relate to the same part of the text or mutually exclude each other, a vote is held on which of the two is to be accepted.
If it is not possible to vote on which proposal to accept, then the proposals shall be voted on individually.
No vote is held on unopposed proposals.
The number of votes is always counted in the case of:
votes on entire bills;
votes on a compromise motion;
votes on provisions requiring the agreement of a majority of the members of each of the two parliamentary councils (Art. 159 para. 3 Cst.);
