Mandatory referendum

The mandatory referendum (German: obligatorisches Referendum, French: référendum obligatoire, Italian: referendum obbligatorio, Romansh: referendum obligatoric) is an instrument of direct democracy in Switzerland. It is a mechanism that holds mandatory votation of some decisions of the federal, cantonal, or municipal parliament and/or government, such as modifications of the Constitution or adhesion to supranational communities on a federal or cantonal level, or for example substantial financial decisions decreed by cantonal and/or communal executive and/or legislative bodies.

In the case of amendments to the federal constitution any change to the law requires both a majority of the valid votes cast and the majority of the cantons (double majority).
