Date of the referendum

a. The absolute minimum period between calling a referendum and polling day should be four weeks. A considerably longer period of preparation is desirable, however, particularly if the topic has not already been subject to widespread public discussion. The campaign period must not be shorter than for regular elections.

b. The law should provide for a maximum period between the submission of signatures for a referendum or a popular initiative and the vote.

c. It is suitable not to hold elections and referendums on the same day if the referendum is about the institution facing election.
