Re Metropolitan Health Service Board;

The matter before the court involved the Metropolitan Health Service Board, which had revoked the clinical privileges of a medical practitioner attached to a teaching hospital. The practitioner sought certiorari to challenge the Board's decision, arguing that it was a jurisdictional error and that procedural fairness was denied. The case was heard in the Court of Appeal in Western Australia.

The primary legal issues were whether the Board's decision to revoke the practitioner's clinical privileges constituted a jurisdictional error and whether the decision-making process denied procedural fairness. Additionally, the court examined the concept of legitimate expectation and the meaning of "Wednesbury unreasonableness" in the context of administrative decisions.

The court found that the Board's decision did not amount to a jurisdictional error, as the Board had the authority to revoke clinical privileges under the relevant legislation. However, the court did find that procedural fairness was denied. The practitioner had a legitimate expectation of a fair process before any decision to revoke privileges was made, and this expectation was not met. The court also noted that the Board's decision could be considered "Wednesbury unreasonable" as it lacked a rational basis and was disproportionate to the circumstances. The Board's decision was quashed, and the matter was remitted for reconsideration.

The court ordered that the decision of the Board be quashed and that the matter be remitted to the Board for reconsideration in accordance with the principles of procedural fairness. The Board was also directed to provide the practitioner with an opportunity to be heard before any further decision was made regarding the revocation of clinical privileges.
