This case commentary discusses the landmark case of St Helen's Smelting Co v Tipping, which dealt with the principles of nuisance and the law of torts. The case involved a claimant who owned a manor house and land near a copper smelting business, and brought a nuisance action against the defendant for damages caused by their operations. The court held that the principle of locality was not relevant where there was physical damage to property, and that there was no defence of coming to nuisance. The commentary also discusses the broader principles of tort law and the importance of maintaining legality in cases of nuisance.
