Only expenditure necessary to pay debts due and expenditure for which the law has expressly so decided is compulsory for the local authority.
The territorial audit chamber to which a matter has been referred, either by the State representative, or by the public accountant concerned, or by any person with an interest, establishes that a compulsory expenditure has not been entered in the budget or has been entered for an insufficient sum. It makes this observation within a period of one month from the date of referral and sends formal notice to the local authority.
If, within a period of one month, this formal notice is not acted upon, the territorial audit chamber asks the representative of the State to enter this expenditure in the budget and proposes, if necessary, the creation of resources or the reduction of optional expenditure intended to cover the compulsory expenditure. The State representative settles and implements the rectified budget accordingly. If he departs from the proposals formulated by the territorial audit chamber, he shall give explicit reasons for his decision.
