Section 57-01-07 - Review of sales, market, and productivity study by state tax commissioner - Appeal1. The state tax commissioner shall notify each county board of commissioners of a scheduled hearing of the sales, market, and productivity study before the state tax commissioner. Such notice must set forth the time and date and place of such hearing. After hearing objections to using certain sales in the study, the state tax commissioner is authorized to withdraw such sales that the state tax commissioner deems are not representative. Within thirty days after the close of such formal hearing, the state tax commissioner shall notify each county board of commissioners, in writing, as to the action taken as a result of such hearing. Within ten days after receiving such notice from the state tax commissioner, each board of county commissioners may appeal the decision of the state tax commissioner to the state board of equalization. Such board will review the findings of the state tax commissioner and render its final decision on such appeal.2. No sale may be used in any sales, market, and productivity study until it has been verified by the state tax commissioner, the county supervisor of assessments, township supervisors, or the board of county commissioners or its agent that none of the exclusions set forth in section 57-01-06 have been used in the study.
