Prior to 2016, the county legislative body was required to elect three competent citizens to be county revenue commissioners every two years during its July meeting. These revenue commissioners were required to meet four times a year to examine the settlements of the county mayor with all of the officers of the county who collect money, review all of the financial reports, review disbursements from the county treasury and examine the books of these officers if necessary. The county revenue commissioners were required to report the results of their investigations at the end of each quarter. T.C.A. § 5-8-601 et seq. In 2016, the legislature deleted the provisions relating to revenue commissioners (Public Chapter 624). The legislative changes did not remove incumbents from office, but no new revenue commissioners will be elected.
