Relevant Considerations in Judicial Review — Minister for Aboriginal Affairs v Peko-Wallsend

Minister for Aboriginal Affairs v Peko-Wallsend Ltd (1986) 162 CLR 24 is the foundational Australian authority on the “relevant considerations” ground of judicial review — the ground engaged where a decision-maker fails to take into account a consideration they were bound to take into account.

Mason J’s framework

  • The ground is only made out where the decision-maker fails to consider a matter they are bound to consider — and what they are bound to consider is determined by the statute, expressly or by implication from its subject-matter, scope and purpose.
  • Where the discretion is unconfined, the factors that may be considered are similarly unconfined, subject to any implied limitation from the statute’s purpose.
  • Not every failure vitiates: the consideration must be material enough that ignoring it could have affected the outcome — insignificant matters do not ground review.
  • The weight to be given to a relevant consideration is generally for the decision-maker, reviewable only on Wednesbury-style unreasonableness grounds.
  • A minister deciding personally is bound to consider the most recent and accurate material on a critical issue in the department’s possession — the proposition for which Peko-Wallsend is most often cited.

Where the ground sits today

The ground is codified for Commonwealth decisions in ss 5(2)(a)–(b) of the Administrative Decisions (Judicial Review) Act 1977 (Cth) and remains available at common law and under s 75(v) of the Constitution as a species of jurisdictional error. Australian Broadcasting Tribunal v Bond (1990) 170 CLR 321 remains the companion authority on what counts as a reviewable “decision” under the ADJR Act.
