Voters can also use the Cerfa form n°15264*02 to deposit in their town hall their support for a referendum bill.
FYI
The referendum on a shared initiative is provided for in the Constitution. It can be organized on the initiative of 1/5e Members of Parliament, supported by 1/10e registered voters.
If enough voters give their support, the bill is considered by the parliament or put to a referendum by the president of the republic.
