Brocklands Pty Ltd v Tasmanian Networks Pty Ltd

Brocklands Pty Ltd (the plaintiff) brought proceedings against Tasmanian Networks Pty Ltd (the defendant) in the Supreme Court of Tasmania. The dispute concerned damage allegedly caused by high voltage electricity entering the plaintiff's low voltage system. The plaintiff asserted multiple breaches of the defendant's duties of care, leading to the damage.

The central legal issue before the Full Court of the Supreme Court of Tasmania was whether the plaintiff was required to prove which specific breach of duty by the defendant caused the damage, or if it was sufficient to establish that the damage was caused by the defendant's negligence, even if the precise causative breach could not be identified from multiple asserted breaches.

The Court held that where a plaintiff establishes that damage was caused by the defendant's negligence, and there are multiple asserted breaches of duty, it is not necessary for the plaintiff to prove which particular breach was causative. The Court applied the principle that a defendant is liable if their negligence causes damage, and the difficulty in pinpointing the exact causative breach does not absolve them of responsibility if the overall negligence is established.

The Court found in favour of the plaintiff, determining that the damage was caused by the defendant's negligence, and therefore the plaintiff was entitled to succeed in its claim.
