386. Upon adopting its budget or a supplementary budget, the Regional Government may, by ordinance, for the purpose of paying its expenses or part of its expenses, determine in accordance with section 385 and require an aliquot share of such expenses or of part of such expenses to be paid by each municipal corporation in its territory.
In order to pay such aliquot share imposed upon it hereunder, any municipal corporation shall have the powers mentioned in section 218.
The aliquot share shall be paid within three months following the date of the receipt by the municipal corporation of the demand for payment of such share.
A municipal corporation in the territory may, by motion filed within three months after the date mentioned in the third paragraph, apply to the Commission municipale du Québec to obtain the revision of the budget or supplementary budget of the Regional Government. The Commission shall render its decision and notify the Regional Government as well as the municipal corporations in the territory within three months of the filing of such motion. In rendering its decision, after having heard those desiring to be heard, the Commission may either maintain the budget or supplementary budget, or effect, in the place and stead of the Regional Government, a reduction of the expenses and an adjustment of the aliquot share accordingly, if it is convinced that the budget or supplementary budget entails a serious prejudice for the ratepayers of a municipal corporation in the territory. The Commission shall then fix a new delay for the payment of the aliquot share. If need be, it shall also fix a delay for the reimbursement of the amounts to be reimbursed by the Regional Government.
