The claimant appealed the LAT’s dismissal of his catastrophic impairment dispute, arguing that the Tribunal’s supplemental reasons contained in the reconsideration decision violated the principles of fairness. The Court dismissed the appeal, holding that the SPPA gave the Tribunal the power to make rules to reconsider its own decision, and that the reconsideration process gave the Tribunal the ability to dismiss, confirm, vary, or cancel any part of its original decision or order. The Tribunal’s procedure in the subject matter followed the reconsideration process contemplated by the SPPA and the Tribunal’s own rules. The Tribunal acted entirely within its own jurisdiction on the reconsideration.
