O'Dea v Western Australia [2022] HCA 24

O'Dea v Western Australia [2022] HCA 24

Section 7(a) of the Criminal Code (WA) requires that an accused is criminally responsible only for his or her own acts that constitute the offence, not for acts of another unless agency in law applies. Attributing the acts of a co-accused under a jury direction that allows a conviction based on a combination of acts done 'in concert', rather than the accused’s own acts, is inconsistent with the text and structure of the Code, and constitutes an error of law warranting a retrial.

Procedural Posture

Criminal Appeal / High Court Appeal From the Supreme Court of Western Australia Court of Appeal

Legal Issues

  1. 1 Whether s 7(a) of the Criminal Code (WA) permits attribution of another’s acts to an accused as a 'joint principal' where the accused did not 'actually do the act' constituting the offence
  2. 2 Whether the trial judge erred in directing the jury that a combination of acts could form the basis of criminal responsibility under s 7(a)
  3. 3 Whether lawfulness or otherwise of a co-accused's acts is material to the application of s 7(a)

Ratio Decidendi

Section 7(a) of the Criminal Code (WA) requires that an accused is criminally responsible only for his or her own acts that constitute the offence, not for acts of another unless agency in law applies. Attributing the acts of a co-accused under a jury direction that allows a conviction based on a combination of acts done 'in concert', rather than the accused’s own acts, is inconsistent with the text and structure of the Code, and constitutes an error of law warranting a retrial.
