(a) On a matter over which TRS has jurisdiction and authority to grant relief that does not conflict with the terms of the pension plan, a person may appeal a final administrative decision by filing a petition for adjudicative hearing with the deputy director. The petition shall conform to the requirements of §43.12 of this chapter (relating to Form of Petitions and Other Pleadings).     
      (b) A petition for adjudicative hearing must be filed by the later of:      
        (1) 45 days after the date the final administrative decision is mailed; or       
        (2) a number of days after the final administrative decision is mailed equal to the number of days it took TRS to issue the final administrative decision.       
      (c) The number of days it took TRS to issue the final administrative decision is calculated from the date TRS received the person's appeal of the department manager's decision to the date TRS mailed the final administrative decision.
