29. The council may provide sufficient appropriations in the budget of the municipality for the reimbursement, pursuant to section 26 or 27, of expenses entailed by particular classes of acts that the members of the council may perform on behalf of the municipality as part of their duties.
The prior authorization provided for in section 25 in respect of an act of a class for which appropriations are provided in the budget is limited to the authorization to perform the act, without reference to the maximum amount of expenses allowed. The maximum amount is deemed to be the balance of the appropriations for acts of that class, after deducting all previous reimbursements, or, where applicable, the amount prescribed in the tariff for that act.
If no appropriations are available, the council may appropriate sums of money out of the general fund of the municipality for the purposes of the first paragraph; the sums so appropriated are deemed to be appropriations.
