Section 23.(A) First Adjustment. Prior to the end of the third year after the effective date of this constitution, the assessors and the Louisiana Tax Commission or its successor shall complete determination of the fair market value or the use value of all property subject to taxation within each parish for use in implementing this Article. Except as provided in this Section, the total amount of ad valorem taxes collected by any taxing authority in the year in which Sections 18 and 20 of this Article are implemented shall not be increased or decreased, because of their provisions, above or below ad valorem taxes collected by that taxing authority in the year preceding implementation. To accomplish this result, it shall be mandatory for each affected taxing authority, in the year in which Sections 18 and 20 of this Article are implemented, to adjust millages upwards or downwards without regard to millage limitations contained in this constitution, and the maximum authorized millages shall be increased or decreased, without further voter approval, in proportion to the amount of the adjustment upward or downward. Thereafter, such millages shall remain in effect unless changed as permitted by this constitution.

            (B) Subsequent Adjustments. Except as otherwise permitted in this Section, the total amount of ad valorem taxes collected by any taxing authority in the year in which the reappraisal and valuation provisions of Section 18, Paragraph (F) of this Article are implemented shall not be increased or decreased because of a reappraisal or valuation or increases or decreases in the homestead exemption above or below the total amount of ad valorem taxes collected by that taxing authority in the year preceding implementation of the reappraisal and valuation. To accomplish this result, the provisions of millage adjustments relative to implementation of Section 18 and Section 20 of this Article, as set forth in Paragraph (A) of this Section shall be mandatory. Thereafter, following implementation of each subsequent reappraisal and valuation required by Paragraph (F) of Section 18 of this Article, the millages as fixed in each such implementation shall remain in effect unless changed as permitted by Paragraph (C) of this Section.

            (C) Increases Permitted. Nothing herein shall prohibit a taxing authority from collecting, in the year in which Sections 18 and 20 of this Article are implemented or in any subsequent year, a larger dollar amount of ad valorem taxes by (1) levying additional or increased millages as provided by law or (2) placing additional property on the tax rolls. Increases in the millage rate in excess of the rates established as provided by Paragraph (B) above but not in excess of the prior year’s maximum authorized millage rate may be levied by two-thirds vote of the total membership of a taxing authority without further voter approval but only after a public hearing held in accordance with the open meetings law; however, in addition to any other requirements of the open meetings law, public notice of the time, place, and subject matter of such hearing shall be published on two separate days no less than thirty days before the public hearing. Such public notice shall be published in the official journal of the taxing authority, and another newspaper with a larger circulation within the taxing authority than the official journal of the taxing authority, if there is one.

            (D) Application. This Section shall not apply to millages required to be levied for the payment of general obligation bonds.
