(2) In filing the assessments made by the comptroller of the treasury with the board of equalization as required in § 67-5-1327, the comptroller of the treasury shall set out the assessments as determined by the comptroller of the treasury in accordance with the constitutional level of assessments.

No back assessments of CIP, as the term is used in § 67-5-903(g), shall occur prior to January 1, 1994. If back assessments have occurred involving CIP, those assessments shall be voided and all taxes paid shall be refunded to those taxpayers who have an action or claim pending before an assessing authority or court on the CIP issue.
