The county election commission meets on the call of its chairperson (if there is no chair, the oldest member presides). T.C.A. § 2-1-113. All meetings must be open to the public and preceded by adequate notice, as required by Tennessee's sunshine law. T.C.A. § 8-44-101 et seq. This notice must give the time, place, and purpose for the meeting, although the requirement may be met by permanently posting a conspicuous meeting notice in the commission office. The commission must keep official minutes of each meeting, including the vote of each member on all issues, and must allow reasonable times for public examination. A majority of the members constitutes a quorum, and a measure passes on a majority vote of the members present. Any action taken that does not meet these requirements can be voided at the request of anyone who may be adversely affected. T.C.A. § 2-1-113.
