Private Nuisance Part I

1. Definition and the three types

The orthodox definition, taken from Winfield & Jolowicz on Tort (2021), is that private nuisance is "any unlawful interference with a person's use or enjoyment of land, or some right over or in connection with it". The key gloss is that "unlawful" means unreasonable: not every annoyance grounds a claim, and a measure of give-and-take between neighbours is expected (Lawton LJ in Kennaway v Thompson). Substantial physical damage, however, is treated as per se unlawful.

Three categories of interference:

• Encroachment — overhanging branches, invading roots, projecting eaves.
• Direct physical injury to land or chattels — fumes scorching foliage, vibrations cracking walls.
• Interference with use and enjoyment — smells, smoke, noise, dust, light, vibrations.

Lord Hoffmann in Hunter v Canary Wharf emphasised that nuisance is a tort affecting land, concerned with the diminished utility of the property rather than the personal discomfort of those occupying it. Consequences: only those with an interest in land can sue; the test of unreasonableness is objective, so a claimant's particular sensitivity is disregarded; damage to chattels is recoverable only as consequential to damage to land; and personal injury is excluded altogether.

2. Standing — who can sue?

Because nuisance protects proprietary interests, the claimant must have a sufficient interest in the affected land.

Hunter applied Malone v Laskey [1907] 2 KB 141, where a tenant's wife injured by vibrations causing a cistern to fall was denied a nuisance remedy: no interest in the land. Coase rationale: only those with proprietary entitlements can negotiate over polluting rights.

Article 8 ECHR (HRA 1998). In McKenna v British Aluminium [2002] EWHC 2034, Neuberger J suggested obiter that Article 8 might expand standing. In Dobson v Thames Water [2009] EWCA Civ 28, the Court of Appeal treated nuisance and HRA claims as conceptually distinct: a non-titleholder occupant can sue under the HRA, but where the titleholder has recovered substantial nuisance damages, additional just-satisfaction is unlikely. The HRA operates as a parallel route, not a competing one.

3. Possible defendants — who can be sued?

Three categories: creator, occupier (whether they created it or failed to abate it), and landlord who authorised it.

(a) Creator. Always liable, even if no longer in occupation: Fennell v Robson Excavations [1977] 2 NSWLR 486. Where a developer has gone into liquidation, suing the contractor may be the only practical option.

(b) Occupier. Liable for nuisances they create and, more controversially, for those created by trespassers, prior occupiers or natural causes that they adopt or continue.

The logic extends to natural causes. In Goldman v Hargrave [1967] 1 AC 645 (PC), lightning struck a tree on D's land; he cut it down but let embers smoulder, wind reignited the fire and it spread. D was liable for failing to take reasonable abatement steps. The duty is measured, accounting for the defendant's physical and financial resources (Lambert v Barratt Homes [2010]; Vernon Knight v Cornwall CC [2013]). Leakey v National Trust [1980] QB 485 extended this to natural land movement: a mound collapsed onto C's cottage and the Trust was liable for knowing of the risk and doing nothing.

(c) Landlord. Liable where they have expressly or impliedly authorised the nuisance, or knew of an existing one at the lease date and failed to act. In Cocking v Eacott [2016] EWCA Civ 140, a mother let her adult daughter live rent-free in her flat; the daughter kept a constantly-barking dog and shouted at neighbours. Having retained possession (a licence, not a lease) and known of the disturbance, the mother was liable.

4. Unreasonable interference — the factors

Outside the physical-damage shortcut, unreasonableness is established by weighing a non-exhaustive list of factors. Lawton LJ in Kennaway: "there must be a measure of give and take, live and let live".

(a) Nature and extent of the interference

Always relevant: duration, frequency, timing, intensity. In Kennaway v Thompson [1981] QB 88, the claimant inherited land next to a motorboat racing club whose activities had escalated over decades into internationally publicised events. The Court of Appeal granted an injunction restricting (not prohibiting) racing — escalation tipped a tolerated activity into nuisance. Crown River Cruises v Kimbolton Fireworks [1996] 2 Lloyd's Rep 533 shows even a short event qualifies: a 15-20 minute display ignited a moored barge — intensity outweighed brevity.

(b) Locality

Considered only in amenity cases (after St Helen's Smelting). Thesiger LJ in Sturges v Bridgman (1879) 11 Ch D 852: "what would be a nuisance in Belgrave Square would not necessarily be so in Bermondsey". A doctor built a consulting room next to a confectioner; the mortar noise, previously unobjectionable, became actionable through the new use. Two propositions: coming to the nuisance is no defence, and locality is judged at the date of the alleged nuisance. Adams v Ursell [1913] 1 Ch 269 (chip shop in a fashionable street) and Rushmer v Polsue & Alfieri [1906] 1 Ch 234 (printing presses, trading district) confirm locality sets a baseline but excessive interference is still unreasonable.

(c) Planning permission

Planning may change the character of the locality — but only at strategic scale. It does not immunise the activity.

Whether planning changes locality is fact-specific. Gillingham BC v Medway Dock [1993] QB 343 held that strategic permission to redevelop a disused naval dockyard as a commercial port did so. By contrast, Wheeler v Saunders [1996] Ch 19 (pig farm expansion) and Watson v Croft Promosport [2009] EWCA Civ 15 (motor-racing) held that local-scale permissions did not alter rural character.

(d) Claimant sensitivity

If the harm is attributable to an unusually sensitive use that would not trouble an ordinary occupier, the claim fails. In Robinson v Kilvert (1889) 41 Ch D 88, heat from D's manufacturing damaged C's heat-sensitive brown paper stored above; ordinary paper would not have been affected — no nuisance. Heath v Mayor of Brighton (1908) 98 LT 718 (power station noise said to disrupt clergy preparing sermons) is similar. Once actionable to ordinary uses, however, full recovery follows even for sensitive property: in McKinnon Industries v Walker [1951] 3 DLR 577 (PC), poisonous fumes that would have damaged ordinary plants also destroyed C's commercial orchids — recoverable in full.

The modern reframing: in Network Rail v Morris [2004] EWCA Civ 172, electromagnetic emissions from new signalling interfered with guitar amplification in C's studio. Sensitivity collapsed into reasonable foreseeability: D could not foresee so unusually sensitive a neighbouring use.

(e) Malice

Where the defendant acts to annoy the claimant, an otherwise reasonable use becomes unreasonable. In Christie v Davey [1893] 1 Ch 316, C gave music lessons from home; D retaliated by banging trays, whistling and shouting, timed to her lessons — nuisance, calculated to annoy. Hollywood Silver Fox Farm v Emmett [1936] 2 KB 468: D fired shotguns near the boundary to disrupt breeding of C's silver foxes — nuisance, despite shooting on one's own land being ordinarily lawful.

The limit is Bradford Corporation v Pickles [1895] AC 587: D deliberately interfered with percolating water under his land to force a buy-out. No nuisance — the corporation had no protected legal right to the water. Malice cannot create a right that does not exist; it only colours conduct that interferes with an existing right.

(f) Public utility

The public benefit of D's activity is not a defence. Per Bramwell B in Bamford v Turnley (1862) 3 B&S 66, public benefit is weighed only after C is compensated for the invasion. Coventry v Lawrence confirmed social value is "generally no defence" (Lord Carnwath [193]); it is relevant at the remedies stage (Topic 15).

5. Reasonable foreseeability of the harm

Nuisance is no longer purely strict. After Cambridge Water v Eastern Counties Leather [1994] 2 AC 264, the claimant must show the kind of damage was reasonably foreseeable. Spilt PCE solvent unforeseeably percolated through chalk to contaminate C's borehole years later; the House of Lords held Wagon Mound remoteness applies in nuisance, defeating the claim. Network Rail v Morris (above) extends foreseeability to sensitivity — making it the unifying explanation for occupier "adoption" liability (Sedleigh-Denfield, Goldman) and the malice cases (intentional annoyance is paradigmatically foreseeable). Proviso: foreseeability bears on damages, not on injunctions restraining ongoing interference.

6. Application framework

1. Identify the interference — encroachment, physical damage, or amenity? Physical-damage cases (St Helen's Smelting) shortcut the locality analysis.
2. Standing — does the claimant have a proprietary or possessory interest (Hunter; Malone)? If not, consider an HRA Article 8 claim (Dobson).
3. Defendant — creator (Fennell), occupier who created/adopted/continued (Sedleigh-Denfield; Goldman; Leakey), or landlord who authorised (Cocking)?
4. Reasonableness — work the factors in order: nature/extent (Kennaway), locality and any relevant planning permission (Sturges; Coventry), sensitivity (Robinson; Network Rail), malice (Christie; Hollywood), and explicitly note that public utility goes to remedies, not liability.
5. Foreseeability — was the kind of damage reasonably foreseeable (Cambridge Water)? Defences and remedies belong to Topic 15.

7. Common pitfalls

8. Exam checklist

• Classified the interference (encroachment / physical damage / amenity) and applied the St Helen's Smelting shortcut where appropriate.
• Stated Hunter v Canary Wharf as the standing rule and tested whether C has a proprietary or possessory interest; flagged HRA/Article 8 if not.
• Identified all potential defendants — creator, occupier (including Sedleigh-Denfield/Goldman adoption/continuation), and any landlord who authorised.
• Worked the reasonableness factors in a structured order: nature/extent, locality, planning, sensitivity, malice.
• Cited the locality language from Sturges v Bridgman ("Belgrave Square / Bermondsey") and used Coventry v Lawrence on planning.
• Reframed any sensitivity argument through the foreseeability lens of Network Rail v Morris.
• Addressed reasonable foreseeability of harm under Cambridge Water.
• Noted that public utility is a remedies-stage factor, not a liability defence — and signalled that defences and remedies are addressed in Topic 15.
