The optional referendum (German: Fakultatives Referendum; French: Référendum facultatif) is an instrument of direct democracy in Switzerland. It allows citizens to oppose to laws voted by the parliament. A votation will be organised for every law that collected 50,000 valid signatures of opponents.

It is different from the mandatory referendum in that a collection of signatures is necessary to organise the referendum.


After pressure of a grass-roots movement, the optional referendum was introduced in 1874.[1]
