The Legislative Authority shall determine its own rules, and keep a journal of its proceedings. It may punish or expel any member for disorderly conduct or violation of its rules, and declare his or her seat vacant for absence without valid excuse, where the absence has continued for two months. No expulsion shall take place without the concurrence of two-thirds of all the members elected, and until the delinquent member has been notified of the charge against him or her, and has had an opportunity to be heard.
(R.C. § 731.45)
