Nuisance — private and public
The law of nuisance protects rights in land from unreasonable interferences and certain public wrongs.
Overview
The tort of nuisance occupies a distinct position within the architecture of civil liability. Unlike negligence, which vindicates personal security and economic interests, nuisance protects rights in land. It does so by imposing liability for interferences that either unreasonably diminish the use and enjoyment of neighbouring property (private nuisance) or materially affect a class of the public in the exercise of common rights (public nuisance). The two torts share a name but diverge sharply in history, doctrinal structure, and practical application.
Private nuisance is a tort against land. Only a person with a proprietary or possessory interest may sue; mere licensees and members of the occupier's household cannot (Hunter v Canary Wharf Ltd [1997]). The gist of the action lies in balancing the competing interests of neighbouring landowners: the defendant's freedom to use her land must be reconciled with the claimant's right to enjoy his. Reasonableness — assessed by reference to locality, duration, intensity, utility, and malice — is the organising concept. Nuisance is not a strict liability tort; it requires either an unreasonable interference or a failure to abate a known hazard. Defences and remedies reflect the equitable origins of the jurisdiction: injunctions are the primary remedy, though damages may be awarded in lieu or in addition.
Public nuisance, by contrast, is historically a crime: an act or omission that materially affects the reasonable comfort and convenience of a class of Her Majesty's subjects. A private individual may sue only if she suffers 'special damage' distinct in kind from that suffered by the general public. In practice, public nuisance overlaps with highway obstructions, environmental hazards, and mass exposure cases. Its breadth and flexibility make it attractive to claimants who fall outside the ambit of private nuisance, but its residual criminal character imposes a requirement of unreasonableness akin to fault.
This note examines both torts in turn, tracing their historical development, mapping their current doctrinal contours, and evaluating their normative justifications. It addresses the key tensions: who may sue, what constitutes an actionable interference, how courts balance competing land uses, and whether nuisance law adequately responds to contemporary challenges such as environmental pollution and large-scale construction projects.
