Poyton and Secretary, Department of Social Services (Social services second review)

This matter concerned an appeal by Dr Poyton against a decision of the Social Security Appeals Tribunal (SSAT) which affirmed a decision of the SSAT made on 28 April 2021. The dispute arose from Dr Poyton's contention that the SSAT had failed to correctly implement a prior SSAT decision. This prior decision, made by Member Amundsen on 7 May 2020, had set aside certain Newstart Allowance (NSA) payment decisions made by Centrelink. Dr Poyton argued that the subsequent reconsideration of his NSA entitlement, which included acknowledgement of prior NSA payments, was an error that perpetuated the initial mistake.

The central legal issue before the Tribunal was the meaning and effect of a decision being "set aside" by the SSAT. Specifically, the Tribunal was required to determine whether the setting aside of a decision extended to eliminating the underlying facts upon which that decision was based, or if it merely invalidated the conclusion reached. A further question was whether a subsequent decision-maker could reconsider the same set of underlying facts after a prior decision had been set aside.

The Tribunal reasoned that when a decision is set aside, it is the conclusion derived from an assessment of facts that is invalidated, not the facts themselves. Therefore, a subsequent decision-maker is entitled to reassess the same set of underlying facts. The Tribunal noted that Dr Poyton conceded this point during oral argument. The Tribunal concluded that Member Amundsen's decision to set aside the NSA payment decisions had been correctly implemented by Centrelink's reconsideration of Dr Poyton's entitlement, which was subsequently affirmed by Member Grossman.

Accordingly, the Tribunal affirmed the SSAT's decision of 28 April 2021.
