A forfeiture of service made pursuant to this subsection (a) shall terminate membership in the retirement system in accordance with § 8-35-104 and shall constitute a waiver of all rights in the retirement system on account of the service forfeited.       Any member who has not separated from service may elect to forfeit all service established by such member as a result of employment rendered by the member in a particular employment category provided the forfeiture is for the purpose of establishing such service in another retirement plan operated by:   The federal government;   Another state;   A political subdivision of another state; or   A Tennessee county or municipality that is not a participating employer under Chapters 34 37 of this title.     For purposes of this subsection (b), an “employment category” means employment as a general employee, state police officer, police officer, state judge, county judge, county official or attorney general as such terms are defined in § 8-34-101.     To be effective, the following conditions must be met:  The member must not have received any retirement benefits based upon such service;   The service must be creditable in the other retirement program;   If any of the service is contributory service, the member must take a refund of the member's accumulated contributions attributable to such service pursuant to § 8-37-210;   The member must forfeit all service established by the member as a result of the member's employment in the particular employment category; and   The member must acknowledge in the manner prescribed by the retirement system that by forfeiting the service, the member shall not be entitled to reestablish the service in the retirement system so long as the member is entitled to retirement credit for such service in the other retirement program.     A forfeiture of service made pursuant to this subsection (b) shall constitute a waiver of all rights in the retirement system on account of the service forfeited.
