Regional Express Holdings Limited v Australian Federation of Air Pilots

Regional Express Holdings Limited (Rex) and the Australian Federation of Air Pilots (AFAP) were the parties in this matter before the High Court of Australia. The dispute concerned the interpretation and application of a clause within a certified agreement governing the employment of pilots by Rex. Specifically, the issue revolved around whether Rex was entitled to unilaterally vary the terms of employment for its pilots by introducing a new rostering system, which the AFAP contended was a breach of the agreement.

The High Court was required to determine whether Rex's proposed changes to pilot rostering constituted a unilateral variation of the certified agreement, thereby breaching its obligations under that agreement. A key legal question was whether the agreement, properly construed, permitted Rex to implement such changes without the consent of the AFAP or the affected pilots. The court also considered the nature of the rights and obligations created by the certified agreement and the extent to which it regulated the employer's ability to alter working conditions.

In their joint judgment, Kiefel CJ and Gordon J found that the certified agreement did not grant Rex the unilateral right to vary the rostering arrangements as proposed. Their Honours reasoned that the agreement, when read as a whole, established a framework for determining pilot rosters that involved consultation and agreement, rather than permitting unilateral employer discretion. The court applied principles of contractual interpretation, emphasising the importance of the plain meaning of the words used in the agreement and the context in which they appeared. They concluded that the employer's proposed actions would undermine the agreed terms and conditions of employment, and therefore constituted a breach of the certified agreement.
