Expenses relating to the organisation of the referendum constitute a compulsory expense of the territorial authority that decided on it.
Expenses resulting from electoral assemblies held in communes for the organisation of a referendum decided on by another territorial authority are reimbursed to them by that authority on a flat-rate basis, by means of an allocation calculated on the basis of the number of registered voters in the commune and the number of polling stations set up there. The rates for this grant are set by decree.
