The Owners - Strata Plan No 16460 v Hunter Water Corporation

The Owners - Strata Plan No 16460 commenced proceedings against Hunter Water Corporation in the Supreme Court of New South Wales. The plaintiffs sought damages for loss and damage suffered due to flooding of their properties caused by the bursting of a water main owned and operated by the defendant. The dispute involved claims for property damage loss and a reduction in property value due to the stigma associated with flooding. The primary legal issue before the court was whether the defendant's actions constituted a private nuisance. A secondary issue was whether the unreasonableness of the defendant's interference with the plaintiffs' property was an element of nuisance.

The court considered whether the flooding of the plaintiffs' properties constituted an unreasonable interference with their use and enjoyment of the property. It was established that the flooding was a direct result of the bursting of the water main, which was owned and operated by the defendant. The court examined whether the interference was unreasonable by considering the nature, location, and circumstances of the interference. The court also considered whether the interference was substantial and unreasonable in the sense that it was an unreasonable burden on the plaintiffs' use and enjoyment of their property. The court found that the flooding was indeed unreasonable, as it caused significant damage and disruption to the plaintiffs' properties. The court also held that unreasonableness is an element of nuisance, as it is necessary to establish that the interference was more than a minor inconvenience.

The court awarded damages to the plaintiffs for the loss and damage suffered due to the flooding. The court found that the plaintiffs were entitled to compensation for the diminution in value of their properties as a result of the flooding. The court held that the stigma associated with flooding could be considered in determining the extent of the loss in property value. The court found that the plaintiffs were entitled to compensation for the diminution in value of their properties as a result of the flooding. The court made orders for the defendant to pay damages to the plaintiffs in the amount of $450,000, together with interest and costs.
