Tennessee Code Title 40. Criminal Procedure § 40-22-109

When it satisfactorily appears to the board of parole that a prisoner, whose sentence has been suspended as provided in § 40-22-102, has led an exemplary life and behaved in a manner and for a period of time that leads the board to believe that the prisoner is reliable and trustworthy and that the prisoner will probably remain at liberty without violating the law, and the prisoner's final release is not incompatible with the welfare of society, the board may, in its discretion, parole the prisoner for a period of time as it deems best, or it may recommend to the governor that the governor grant the prisoner a pardon and final discharge.
