Bluescope Steel (AIS) Pty Limited v MacKinnon & Ors

The Full Federal Court of Australia heard an appeal concerning a dispute between Bluescope Steel (AIS) Pty Limited and the respondents, Mr. MacKinnon and others. The core of the disagreement revolved around the interpretation and application of certain provisions within an enterprise agreement governing the employment of the respondents.

The primary legal issues before the Full Court were whether the employer, Bluescope Steel, had breached the enterprise agreement by failing to pay certain allowances to the respondents, and consequently, whether the respondents were entitled to recover those unpaid allowances. This involved a close examination of the specific clauses within the agreement that dealt with the calculation and payment of allowances, particularly in circumstances where employees performed duties that might fall under multiple allowance categories.

The Court's reasoning focused on the plain language of the enterprise agreement and the established principles of contractual interpretation. It considered whether the agreement mandated the payment of all applicable allowances or if it allowed for the aggregation or selection of a single allowance in certain situations. The judges analysed the specific duties performed by the respondents and compared them against the criteria for each allowance stipulated in the agreement. The Court ultimately found that the agreement required the payment of all allowances that an employee was entitled to, based on the duties performed, and that the employer's practice of paying only one allowance in such circumstances was a breach of the agreement.

Consequently, the Full Federal Court allowed the appeal, finding in favour of the respondents and ordering that Bluescope Steel (AIS) Pty Limited pay the outstanding allowances to Mr. MacKinnon and the other respondents.
