It is common in administrative law regimes for tribunals to have authority to 'review' (more commonly referred to as 'reconsider') their decisions. The range of such reviews can be minor - as in the case of review for calculation or typographical errors - or major, in the sense of a full legal and fact-finding review of the decision and order made at hearing.
An SPPA-governed tribunal may make s.25.1 rules on the review of their orders. If that is done it may - within a reasonable time - "review all or part of its own decision or order, and may confirm, vary, suspend or cancel the decision or order" [SPPA s.21.2(1)(2)].
