25. No member may, as part of his duties, perform any act involving expenses chargeable to the municipality except with the prior authorization of the council to perform the act and, consequently, incur expenses which do not exceed the amount fixed by the council.
However, the mayor, or the warden, is not required to obtain such prior authorization when he performs an act as part of his duties. The same rule applies in the case of a member of the council designated by the mayor or, as the case may be, by the warden to replace him where he is unable to represent the municipality.
