Chugg v Pacific Dunlop Ltd

The High Court of Australia considered an appeal from a decision of the Supreme Court of Victoria concerning an alleged breach of the *Occupational Health and Safety Act 1985* (Vic). The appellant, Mr. Chugg, was the employer of a worker who suffered injury, and the respondent, Pacific Dunlop Ltd, was the employer of the injured worker. The dispute centred on whether Mr. Chugg had failed to provide a safe working environment so far as was practicable.

The primary legal issue before the High Court was the proper construction of section 21 of the *Occupational Health and Safety Act 1985* (Vic), specifically concerning the onus of proof regarding the practicability of measures to ensure a safe working environment. The court was required to determine whether the prosecution bore the burden of proving the impracticability of alternative safety measures, or if the employer bore the onus of proving the practicability of the measures they had taken. This also involved considering the principles of statutory interpretation under section 35(a) of the *Interpretation of Legislation Act 1984* (Vic), which mandates preferring an interpretation that promotes the purpose or object of an Act.

The High Court held that the prosecution bore the onus of proving that it was practicable for the employer to have taken further or different measures to ensure the safety of the employee. The court reasoned that the phrase "so far as is practicable" imposed a positive obligation on the employer, but the prosecution must establish that the employer failed to meet this obligation. This required the prosecution to demonstrate that there were measures available that were practicable and would have prevented the injury. The court rejected an interpretation that would place the burden of proving practicability on the employer, finding it inconsistent with the general principles of criminal law and the specific wording of the section.

The High Court allowed the appeal, quashed the conviction, and ordered that the information be dismissed.
