Commonwealth of Australia v Helicopter Resources Pty Ltd & Ors

The applicant, the Commonwealth of Australia, sought special leave to appeal from a decision of the Full Federal Court. The dispute concerned the application of the accusatorial principle in circumstances where an employee of a corporation, who was not personally charged with an offence, was compelled to give evidence relevant to a pending charge against their corporate employer. The respondent, Helicopter Resources Pty Ltd, argued that the accusatorial principle extended to such compelled examinations of employees, and that section 87 of the *Uniform Evidence Acts* facilitated the admissibility of such evidence as an admission against the corporate employer.

The High Court was required to determine two principal questions. First, whether the accusatorial principle is engaged when an employee of a corporation, who is not personally charged, is compelled to give evidence relevant to a pending charge against their corporate employer. Second, whether the Full Federal Court correctly interpreted and applied section 87 of the *Uniform Evidence Acts* in concluding that compelled evidence from an employee could be treated as an admission against the corporate employer, thereby effectively equating the employee's compelled testimony with the corporation's compelled testimony.

The Commonwealth contended that the Full Federal Court erred in its understanding of both the accusatorial principle and section 87. It argued that the accusatorial principle, as established in cases like *Caltex Oil (Australia) Pty Ltd v The Queen*, was fundamentally concerned with the protection of an accused from being compelled to incriminate themselves. The Commonwealth submitted that this principle did not extend to compelling evidence from a non-charged employee of a corporate accused, as the employee's evidence, even if admissible against the corporation, remained the evidence of the witness and not the corporation's own compelled testimony. Furthermore, the Commonwealth argued that section 87, while facilitating the admissibility of an employee's evidence as an admission against interest, did not alter the common law characterisation of that evidence as being that of the witness, nor did it extend the accusatorial principle to encompass such examinations.

The Commonwealth sought special leave to appeal on the basis that these questions involved important issues of principle with significance extending beyond the immediate case, particularly for regulatory bodies exercising coercive powers. The Court considered the affidavit of Andrew Harrington, which indicated that the underlying proceedings had commenced and were ongoing. The Commonwealth offered to pay the reasonable costs of the respondent in defending the appeal, framing the case as a test case to clarify the law in this area.
