After expiry of the referendum period, the Federal Chancellery shall establish whether the referendum request lists contain the required number of valid signatures. If less than half of the quorum required under the Constitution has been achieved, a notice shall be published in the Federal Gazette stating simply that the period allowed for the collection of signatures has expired. If half or more of the required quorum has been achieved, the Federal Chancellery shall issue a ruling confirming whether or not the request for a referendum has been successful.¹
The following are invalid:
1. ² signatures on lists that do not fulfil the requirements of Article 60;
2. ³ signatures by persons whose eligibility to vote is not certified;
