What it does
The Judicial Review Act 1991 establishes a statutory code for challenging administrative decisions, conduct and failures to decide in Queensland. At its core it creates a right for a "person aggrieved" to apply to the Supreme Court for a "statutory order of review" in respect of any "decision to which this Act applies" (s 4 and s 20). That phrase is deliberately broad: it encompasses (a) decisions of an administrative character made under an enactment (whether discretionary or not) and (b) administrative decisions made by the State, a State authority or local government under a non-statutory scheme or program funded in whole or part from parliamentary appropriations or from a tax, charge, fee or levy authorised by enactment (s 4(1)).
The Act then defines what counts as the "making of a decision" (s 5). The list is exhaustive and includes making, suspending, revoking or refusing orders, certificates, licences, conditions, declarations, demands, retention of articles, or "doing or refusing to do anything else". A report or recommendation required before a final decision is itself deemed a decision (s 6). Conduct engaged in for the purpose of making a decision expressly includes preparatory steps such as taking evidence or holding inquiries (s 8). A failure to make a decision is reviewable either on the ground of unreasonable delay (where no time is fixed) or on the ground that the duty to decide survives the expiry of a fixed period (s 22).
Part 3 supplies the grounds on which a statutory order of review may be sought. Section 20(2) lists nine grounds for review of a completed decision: breach of natural justice, failure to observe required procedures, lack of jurisdiction, lack of authority, improper exercise of power, error of law, fraud, no evidence or other material, and "otherwise contrary to law". Section 21 applies an almost identical list to conduct that has been, is being or is proposed to be engaged in for the purpose of making a decision. Section 23 expands "improper exercise of power" (the ground in ss 20(2)(e) and 21(2)(e)) to include irrelevant considerations, failure to consider relevant matters, bad faith, acting at the behest of another, inflexible application of policy, Wednesbury unreasonableness, uncertainty of outcome, and any other abuse of power. Section 24 sets out the precise evidentiary thresholds that must be met before the "no evidence" ground can be made out.
