Construction, Forestry, Mining and Energy Union & Anor v Anglo Coal (Dawson Services) Pty Ltd

The Construction, Forestry, Mining and Energy Union and Mr. Michael O'Connor (the applicants) brought proceedings against Anglo Coal (Dawson Services) Pty Ltd (the respondent) in the Federal Court of Australia. The dispute concerned the respondent's alleged contravention of section 348 of the *Fair Work Act 2009* (Cth) by taking adverse action against Mr. O'Connor, a union organiser, for exercising a workplace right. Specifically, the applicants alleged that the respondent had dismissed Mr. O'Connor because he had requested information about the respondent's compliance with the *Workplace Relations Act 1996* (Cth) and the *Fair Work Act 2009* (Cth) regarding the payment of redundancy entitlements to employees.

The central legal issue before the High Court of Australia was whether the respondent had taken adverse action against Mr. O'Connor, within the meaning of section 348 of the *Fair Work Act 2009* (Cth), by dismissing him. This required the Court to determine whether Mr. O'Connor's dismissal was motivated, in whole or in part, by his exercise of a workplace right, namely requesting information about compliance with industrial relations legislation.

The High Court, in allowing the appeal, held that the Federal Court had erred in its assessment of the evidence. The Court applied the principles of statutory interpretation and the onus of proof provisions within the *Fair Work Act 2009* (Cth) concerning adverse action. It found that the evidence, when properly considered, established that the respondent's decision to dismiss Mr. O'Connor was substantially influenced by his requests for information, which constituted the exercise of a workplace right. The Court emphasised that the employer's motive is a question of fact, and the statutory presumption of contravention in adverse action cases shifts the burden to the employer to demonstrate that the adverse action was not taken for a prohibited reason.

The High Court set aside the orders of the Full Federal Court and remitted the matter to the Federal Court for further hearing and determination according to law.
