Baiada Poultry Pty Ltd v The Queen

Baiada Poultry Pty Ltd (the appellant) was convicted of an offence under section 21(1) of the *Occupational Health and Safety Act 2004* (Vic). The charge arose from a fatal incident on a farm where an independent contractor, engaged by the appellant, was killed while loading crates of chickens onto a trailer. The appellant appealed its conviction to the Court of Appeal of Victoria, which found that the trial judge had erred in failing to direct the jury that the prosecution must prove beyond reasonable doubt that the appellant's engagement of subcontractors was insufficient to discharge its statutory duty. Despite this finding, a majority of the Court of Appeal applied the proviso to section 568(1) of the *Crimes Act 1958* (Vic), dismissing the appeal on the basis that no substantial miscarriage of justice had occurred. The appellant then appealed to the High Court of Australia.

The High Court was required to determine whether the Court of Appeal erred in applying the proviso to section 568(1) of the *Crimes Act 1958* (Vic). Specifically, the Court had to consider whether, in light of the trial judge's misdirection regarding the prosecution's burden of proof concerning the appellant's statutory obligations under the *Occupational Health and Safety Act 2004* (Vic), it could be concluded that no substantial miscarriage of justice had occurred. The central legal issue was whether the evidence, as presented at trial and considered by the Court of Appeal, was sufficient to satisfy the jury beyond reasonable doubt of the appellant's guilt, notwithstanding the identified error in the jury directions.

The High Court allowed the appeal, holding that the proviso to section 568(1) of the *Crimes Act 1958* (Vic) could not be engaged. The Court reasoned that the trial judge's failure to direct the jury on the necessity for the prosecution to prove beyond reasonable doubt that the appellant had not discharged its duty under section 21(1) of the *Occupational Health and Safety Act 2004* (Vic) meant that the appellate court could not be satisfied that no substantial miscarriage of justice had occurred. Consequently, the High Court set aside the order of the Court of Appeal and ordered that leave to appeal be granted, the appeal be allowed, the conviction and sentence be quashed, and a new trial be had.
