Each municipality must adopt a code of ethics by ordinance or resolution. Failure to do so can result in ouster of members of the governing body. MTAS has developed a model code of ethics. Municipalities that adopt the model must notify the Tennessee Ethics Commission that they adopted the model, along with the date of adoption. Municipalities that do not adopt the MTAS model must send a copy of their ordinance to the ethics commission. T.C.A. §§ 8-17-103, et seq.
