Construction, Forestry, Mining and Energy Union v Australian Competition and Consumer Commission

The Construction, Forestry, Mining and Energy Union, along with two natural person applicants, sought leave to appeal an interlocutory judgment from the Federal Court. The appeal concerned allegations of breaches of the Competition and Consumer Act 2010 and the Australian Consumer Law. The applicants had already faced criminal proceedings, and they sought a stay of the civil proceedings until the conclusion of the criminal case. The primary judge dismissed their application, leading to this appeal.

The central legal issues addressed by the court were whether the primary judge erred in his assessment of the prejudice to the natural person applicants. This included the potential "invidious choice" they faced in deciding whether to give evidence in the civil proceeding, the exposure of their defences in the criminal proceeding due to overlapping proceedings, and the burden of managing both. Additionally, the court examined whether the primary judge failed to appropriately consider the primacy of the criminal proceeding and the need to differentiate between private and public applicants in applying principles relevant to a stay.

The court held that the primary judge's discretionary judgment should not be interfered with, even if the weight attributed to certain considerations might be debatable. It was noted that the primary judge had already provided avenues to address any unfairness that might arise during the civil trial. Although the court expressed reservations about certain aspects of the primary judge's reasoning, particularly regarding the potential for jury contamination, it concluded that the intervention of the appellate court at this stage would be premature. The court was satisfied that the primary judge would offer further opportunities to mitigate any anticipated prejudice.

The final orders of the court were to dismiss the application for leave to appeal, allow the applicants seven days to submit any costs arguments, and permit the respondent to reply if the applicants chose to submit costs arguments. If no submissions were made, the applicants would be responsible for the respondent's costs of the appeal application.
