HB 1488 requires Tennessee county legislative bodies (including metropolitan and charter counties) to adopt formal rules for conducting meetings within 90 days of a newly elected body, using a simple majority vote. It mandates that any future changes to these rules must be approved by a two-thirds vote of the body. If the rules don't address a specific issue, the body must follow Robert's Rules of Order as the default procedure. This bill directly affects how county commissions and similar bodies operate, standardizing their internal governance processes.
