Adeels Palace Pty Ltd v Moubarak; Adeels Palace Pty Ltd v Bou Najem

Adeels Palace Pty Ltd was the defendant in proceedings brought by Mr Moubarak and Mr Bou Najem, who were injured when a brawl broke out at a wedding reception held at the defendant's premises. The plaintiffs alleged that the defendant had breached its duty of care by failing to provide adequate security, which led to their injuries. The case proceeded to the High Court of Australia.

The High Court was required to determine whether the defendant owed a duty of care to the plaintiffs in the circumstances, and if so, whether that duty had been breached. A further issue was whether the plaintiffs' injuries were caused by the defendant's breach of duty, and importantly, whether the plaintiffs' own conduct in engaging in the brawl constituted a novus actus interveniens, thereby breaking the chain of causation.

The Court held that the defendant did owe a duty of care to its patrons to take reasonable steps to prevent foreseeable harm, including harm caused by the violent conduct of other patrons. However, the Court found that the plaintiffs' injuries were not caused by any breach of this duty. Instead, their injuries were caused by their own voluntary participation in the brawl. The Court applied the principles of causation, including the "but for" test and the concept of novus actus interveniens, to conclude that the plaintiffs' actions were the direct and effective cause of their injuries, breaking any causal link to the defendant's alleged negligence.

Consequently, the High Court allowed the appeals, finding that the plaintiffs had failed to establish causation and therefore their claims in negligence were dismissed.
