Pacific Dunlop Limited v Chugg; Chugg v Pacific Dunlop Limited; Dairy Farmers Co-operative Limited v Azar

The proceedings before the High Court of Australia involved appeals by Pacific Dunlop Limited and Dairy Farmers Co-operative Limited. The core dispute concerned the interpretation of statutory duties and the onus of proof in relation to exceptions or qualifications within those duties, particularly in the context of workplace safety legislation.

The legal issues before the Court included whether the onus of proof for a statutory exception, such as the phrase "so far as reasonably practicable," should be the same in both civil and criminal proceedings. Furthermore, the Court was required to determine the correct approach to identifying and applying such exceptions in relation to the primary obligation imposed by the statute, specifically whether the exception should be considered before or after the primary obligation.

The Court was presented with arguments that the onus of proof for the "reasonably practicable" qualifier should align with the onus for the primary statutory duty, drawing authority from cases in both Australian and English law. Counsel argued that an obligation is not fully identified until all its qualifying features, including exceptions, have been considered. The submission was that matters of safety must be identified first, and only then can questions of practicability arise, if at all. The Court was also referred to the Minister's second reading speech to illuminate the legislative intent regarding employer duties.
