Pilbara Iron Company (Services) Pty Ltd v Construction, Forestry, Mining and Energy Union

The High Court of Australia considered an appeal by Pilbara Iron Company (Services) Pty Ltd (the employer) against a decision of the Full Federal Court. The dispute concerned the interpretation of a certified agreement and its application to employees who had been transferred from another company, Robe River Iron Ore Company Ltd (Robe River), to the employer. The Construction, Forestry, Mining and Energy Union (the union) contended that these transferred employees were entitled to the benefits of the certified agreement, despite not being directly employed by the employer at the time the agreement was certified.

The central legal issue before the High Court was whether the certified agreement, which applied to employees of the employer engaged in particular work, extended to employees who had been transferred from Robe River to the employer under a business transfer arrangement. Specifically, the court had to determine if the language of the agreement, read in light of the relevant industrial legislation, encompassed these transferred employees, even though they were not employees of the employer at the precise moment the agreement came into effect.

The High Court, in allowing the appeal, reasoned that the certified agreement was intended to regulate the terms and conditions of employment for a defined class of employees. It found that the language of the agreement, particularly clauses relating to the scope of its application, did not extend to employees who were not employed by the employer at the time of certification, even if they subsequently became employees through a transfer. The court emphasised that the agreement was a contract between the employer and its employees, and its terms should be interpreted according to their plain meaning, without importing external assumptions about the parties' intentions or the broader industrial context beyond what was expressly provided. The court concluded that the transferred employees were not covered by the certified agreement.
