Why is "Applying the Occupiers' Liability Act 1957 to a trespasser (or the 1984 Act to a lawful visitor)" a common mistake in Torts affecting land?

Why it happens: Students learn the two Acts together and grab the more familiar 1957 Act without first classifying the claimant. How to avoid it: ALWAYS classify the claimant first. Lawful visitor (permission) → OLA 1957; trespasser (no/exceeded permission) → OLA 1984. State your classification in one sentence before doing anything else, and watch for a change of status by area, time or purpose. Source: 9084 Paper 4 Examiner Reports — Law of Tort

Why is "Confusing private nuisance (indirect interference) with trespass to land (direct interference)" a common mistake in Torts affecting land?

Why it happens: Both protect interests in land, so students treat any interference as 'a nuisance' or 'a trespass' without analysing how the interference occurs. How to avoid it: Ask: is the interference DIRECT (walking on/placing something on the land = trespass, actionable per se) or INDIRECT (noise/smell/smoke drifting across = private nuisance, requiring unreasonableness)? Directness is the dividing line. Source: 9084 Paper 4 Examiner Reports — Law of Tort

Why is "Forgetting the Rylands requirements of NON-NATURAL use and a genuine ESCAPE" a common mistake in Torts affecting land?

Why it happens: Students remember 'a dangerous thing causes harm' but skip the two filtering requirements that actually decide most cases. How to avoid it: Run all FOUR requirements as a checklist: (1) brings/accumulates a dangerous thing; (2) non-natural use — extraordinary/unusual (Transco); (3) it ESCAPES beyond D's land (Read v Lyons); (4) foreseeable damage (Cambridge Water). Apply each to a fact. Source: Transco v Stockport MBC; Read v Lyons; Cambridge Water Co v Eastern Counties Leather

Why is "Allowing a claimant with no proprietary interest to sue in private nuisance" a common mistake in Torts affecting land?

Why it happens: Students focus on whether someone is annoyed and forget that nuisance protects an interest in LAND, not the person. How to avoid it: Check standing first: only a person with a proprietary interest (owner or tenant) can sue in private nuisance (Hunter v Canary Wharf). A lodger, guest or family member with no legal interest cannot. State this before assessing unreasonableness. Source: Hunter v Canary Wharf [1997]

Why is "Describing the law in the abstract instead of APPLYING the section/case to the facts" a common mistake in Torts affecting land?

Why it happens: Students revise the rules thoroughly and want to show their knowledge by 'writing all they know' in a Section A problem. How to avoid it: Use IRAC and tie every element of the rule to a specific fact: 'here, the occupier KNEW children came through the broken fence, so s1(3)(b) OLA 1984 is satisfied.' Application (AO2) is where the marks are; pure description stalls in the middle bands. Source: 9084 Paper 4 Examiner Reports — 'apply the law to the scenario'

Why is "Failing to cite the statute SECTION number AND a leading case (the cap rule)" a common mistake in Torts affecting land?

Why it happens: Students state the rule correctly in their own words but omit the authority, assuming the substance is enough. How to avoid it: Name the authority every time: OLA 1957 s2(2); OLA 1984 s1(3); plus the case (Wheat v Lacon, Glasgow Corp v Taylor, Tomlinson, Sturges v Bridgman, Rylands, Cambridge Water, Transco...). Without sections + cases an answer is capped around Level 2-3. Source: 9084 Paper 4 mark scheme — authority requirement

Torts Affecting Land: Occupiers' Liability, Private Nuisance, Rylands v Fletcher & Trespass — Cambridge AS & A Level Law 9084

These torts protect different interests in land — being safe on someone's premises, enjoying your own land in peace, being free from dangerous escapes, and keeping intruders off your land. This note explains each tort with the exact statute sections and leading cases examiners demand on Paper 4, and shows how to apply them in a 25-mark IRAC problem and a 25-mark evaluative essay.

At a glance

Occupiers' liability splits in two: lawful VISITORS are protected by the Occupiers' Liability Act 1957; TRESPASSERS by the Occupiers' Liability Act 1984. Classify the claimant first — this picks the Act.
OLA 1957 s2(2) = the common duty of care; extra care for children (s2(3)(a), allurement — Glasgow Corp v Taylor; Jolley v Sutton); skilled visitors guard against their own trade risks (s2(3)(b) — Roles v Nathan); warnings (s2(4)(a)); independent contractors (s2(4)(b) — Haseldine v Daw).
OLA 1984 s1(3) — a duty to a trespasser arises only if the occupier (a) is aware of the danger, (b) knows or believes the trespasser may come into the vicinity, and (c) the risk is one against which protection may reasonably be expected. Duty = s1(4); warnings = s1(5); obvious risk / free will = Tomlinson v Congleton BC.
Private nuisance = an unlawful, INDIRECT interference with the use or enjoyment of land. The claimant must have a proprietary interest (Hunter v Canary Wharf).
Unreasonableness factors: locality (Sturges v Bridgman), duration/frequency, abnormal sensitivity (Robinson v Kilvert), and malice (Christie v Davey; Hollywood Silver Fox Farm v Emmett).
Rylands v Fletcher = STRICT liability: (1) bring/accumulate a dangerous thing, (2) non-natural use (Transco), (3) escape (Read v Lyons), (4) foreseeable damage (Cambridge Water).
Trespass to land = a DIRECT, intentional interference with land in another's possession; actionable PER SE (no damage needed).
The cap rule: cite the statute SECTION and the leading case, or be limited to Level 2-3.

Overview: four torts, four different interests in land

Before learning the detail, fix what each land tort protects — and learn to spot which one a scenario raises.

The 'torts affecting land' protect distinct interests, and your first job in any problem is to identify which tort the facts raise. They can — and often do — appear together in one scenario.

Tort	What it protects	Key trigger	Lead authority
Occupiers' liability (OLA 1957)	The safety of LAWFUL VISITORS on premises	A visitor is injured	OLA 1957 s2(2); Wheat v E Lacon
Occupiers' liability (OLA 1984)	Limited safety of TRESPASSERS	A trespasser is injured	OLA 1984 s1(3); Tomlinson v Congleton
Private nuisance	Use / enjoyment of one's OWN land	Indirect interference (noise, smell)	Sturges v Bridgman; Hunter v Canary Wharf
Rylands v Fletcher	Land harmed by a dangerous ESCAPE	Dangerous thing escapes	Rylands v Fletcher; Cambridge Water; Transco
Trespass to land	POSSESSION of land	Direct, intentional intrusion	Actionable per se

How to tell them apart fast:

Someone injured on another's premises → occupiers' liability (then ask: visitor or trespasser?).
Indirect interference (noise, smell, smoke) crossing a boundary → private nuisance.
A dangerous thing escapes from one piece of land to another → Rylands v Fletcher.
A direct, intentional intrusion onto land (walking on it, dumping something on it) → trespass to land.

A single Paper 4 scenario might raise three of these at once (e.g. a chemical works where a delivery driver is hurt, solvent escapes next door, and a smell drifts over). Deal with each as a separate IRAC block.

Occupiers' liability protects people on premises; nuisance/Rylands/trespass protect land itself.
Visitor vs trespasser decides between OLA 1957 and OLA 1984.
Indirect interference = nuisance; an escape = Rylands; a direct intrusion = trespass.
Multi-issue problems are common — analyse each tort separately using IRAC.

Occupiers' liability to visitors — the Occupiers' Liability Act 1957

The common duty of care to lawful visitors, plus the special rules for children, skilled visitors, warnings and contractors.

The occupier is the person with control of the premises (Wheat v E Lacon & Co) — usually the owner, but it is control, not ownership, that matters, and there can be more than one occupier. A lawful visitor is someone with express or implied permission, or a legal right, to be there.

The common duty of care — s2(2). The occupier must take such care as in all the circumstances is reasonable to see that the visitor will be reasonably safe in using the premises for the purposes for which they are permitted to be there. It protects the visitor for the purpose of the visit — not, for example, someone who 'slides down the banisters' when invited only to use the stairs.

Special categories of visitor:

Sub-section	Rule	Case
s2(3)(a) — children	Must expect children to be less careful; beware an allurement (tempting + dangerous)	Glasgow Corporation v Taylor (poisonous berries); Jolley v Sutton LBC (abandoned boat)
s2(3)(b) — skilled visitors	May expect a person exercising their calling to guard against risks ordinarily incidental to their trade	Roles v Nathan (chimney sweeps killed by fumes — occupier not liable)
s2(4)(a) — warnings	A warning discharges the duty only if it makes the visitor reasonably safe	—
s2(4)(b) — independent contractors	Occupier not liable for a contractor's faulty work if reasonable to entrust it, a competent contractor was chosen, and (where reasonable) the work was checked	Haseldine v Daw (specialist lift repair — occupier not liable)

Exclusion and defences. An occupier may try to exclude liability by notice (subject to consumer-protection limits). Defences include consent / volenti (s2(5)) and contributory negligence (which reduces damages).

In Jolley v Sutton, children were injured propping up an abandoned boat; the council argued the precise accident was unforeseeable, but the House of Lords held the wider danger of children playing with the boat was foreseeable — an important illustration of how far the duty to children stretches.

Occupier = the person with control (Wheat v E Lacon); ownership is not required.
s2(2) = the common duty of care — keep the visitor reasonably safe for the purpose of the visit.
Children (s2(3)(a)): beware allurements — Glasgow Corp v Taylor; Jolley v Sutton.
Skilled visitors (s2(3)(b)): expected to guard against their own trade risks — Roles v Nathan.
Warnings (s2(4)(a)) discharge the duty only if they make the visitor reasonably safe; contractors (s2(4)(b)) — Haseldine v Daw.
Defences: consent (s2(5)) and contributory negligence (reduces damages).

Occupiers' liability to trespassers — the Occupiers' Liability Act 1984

A limited duty to trespassers, owed only where the three s1(3) conditions are met — and never to those who freely accept an obvious risk.

A trespasser has no permission to be on the land, or has exceeded the permission given. Since the Occupiers' Liability Act 1984, an occupier may owe a trespasser a limited duty — but only in defined circumstances.

When is a duty owed? — s1(3). A duty arises only if ALL THREE conditions are satisfied:

(a) the occupier is aware of the danger or has reasonable grounds to believe it exists;
(b) the occupier knows or has reasonable grounds to believe the trespasser is (or may come) into the vicinity of the danger; and
(c) the risk is one against which, in all the circumstances, the occupier may reasonably be expected to offer some protection.

The duty — s1(4). If a duty is owed, the occupier must take such care as is reasonable in all the circumstances to see that the trespasser is not injured by the danger concerned.

Warnings — s1(5). The duty may be discharged by taking reasonable steps to give warning of the danger or to discourage people from taking the risk.

The obvious-risk / free-will limit — Tomlinson v Congleton BC. A council owed no duty to a man who was injured diving into a shallow lake despite prohibition signs. The danger was obvious, and the injury arose from his own free choice to take the risk, not from any defect in the premises. Occupiers are not required to 'sanitise' their land against adults who choose to court obvious dangers.

Scope and defences. The 1984 Act protects against personal injury only — not damage to property. Defences include consent / volenti and contributory negligence.

Trespasser = no permission, or permission exceeded → OLA 1984.
s1(3): a duty arises only if (a) aware of the danger, (b) knows/believes the trespasser may be near, (c) protection reasonably expected.
s1(4) = reasonable care to prevent injury by the danger; s1(5) = warnings can discharge the duty.
Tomlinson v Congleton BC: no duty for obvious risks freely accepted.
The 1984 Act covers personal injury only, not property; defences = consent and contributory negligence.

Private nuisance — the unreasonableness factors

An unlawful, indirect interference with the enjoyment of land — actionable only where unreasonable, and only by a claimant with a proprietary interest.

Private nuisance is an unlawful, indirect interference with a person's use or enjoyment of their land — typically noise, smell, smoke, fumes or vibrations crossing from neighbouring land.

Who can sue and be sued. The claimant must have a proprietary interest in the affected land — an owner or tenant — Hunter v Canary Wharf. A mere licensee (a lodger, a guest, a family member with no legal interest) cannot sue. The defendant is usually the creator of the nuisance or the occupier who allows it to continue.

Is the interference UNREASONABLE? This is the heart of the tort. The court weighs several factors:

Factor	Meaning	Case
Locality / character of the area	What is a nuisance in a quiet area may not be in an industrial one (does NOT apply to physical damage)	Sturges v Bridgman — 'Belgrave Square... Bermondsey'
Duration & frequency	Continuous/recurrent and ill-timed interference is more likely a nuisance	—
Abnormal sensitivity	No claim merely because the claimant's use is unusually delicate; test is foreseeability of harm to ordinary use	Robinson v Kilvert; Network Rail v Morris
Malice	Deliberate, spiteful conduct can make lawful activity unreasonable	Christie v Davey; Hollywood Silver Fox Farm v Emmett

Defences:

Prescription — the nuisance has continued for 20 years without complaint.
Statutory authority — the activity is authorised by statute (Allen v Gulf Oil Refining — an Act authorising a refinery covered the inevitable nuisance from operating it).
Planning permission is NOT a defence — permission to develop does not authorise a nuisance.
'Coming to the nuisance' is not a defence.

Remedies:

Injunction — the primary remedy, restraining the nuisance.
Damages — for harm and loss of amenity.
Abatement — limited self-help to stop the nuisance (e.g. cutting back overhanging branches), used cautiously.

Private nuisance = unlawful, INDIRECT interference with use/enjoyment of land.
Standing: only a claimant with a proprietary interest can sue (Hunter v Canary Wharf).
Unreasonableness factors: locality (Sturges v Bridgman), duration/frequency, abnormal sensitivity (Robinson v Kilvert), malice (Christie v Davey; Hollywood Silver Fox Farm v Emmett).
Defences: prescription (20 years), statutory authority (Allen v Gulf Oil) — but planning permission is NOT a defence.
Remedies: injunction (primary), damages, abatement.

Rylands v Fletcher — strict liability for an escape

Four requirements decide liability: bringing a dangerous thing, non-natural use, an escape, and foreseeable damage.

The rule in Rylands v Fletcher (1868) imposes strict liability — liability without proof of fault — where a dangerous thing escapes from a non-natural use of land. But 'strict' does not mean automatic: all FOUR requirements must be satisfied.

1. Bringing / accumulating a dangerous thing. The defendant must bring onto their land, and accumulate there, something likely to do mischief if it escapes (water, gas, chemicals, fire, electricity). Things naturally present on the land are not 'brought'.

2. Non-natural use. The use must be non-natural — extraordinary and unusual, not an ordinary use of land (Transco v Stockport MBC — piping water to a block of flats was an ordinary, natural use, so the rule did not apply). Bulk storage of hazardous substances is typically non-natural; ordinary domestic supply is not.

3. Escape. The dangerous thing must escape from the defendant's land to land outside it. There is no escape — and so no liability — if harm occurs within the defendant's own land (Read v Lyons — an explosion inside a munitions factory).

4. Foreseeable damage. The escape must cause damage of a foreseeable type (Cambridge Water Co v Eastern Counties Leather — the chemical's eventual seepage into a water supply was not foreseeable when it was spilt, so the claim failed). Liability is strict, but the kind of harm must be foreseeable.

Defences: act of a stranger (a third party caused the escape), act of God (an extraordinary natural event), statutory authority, consent of the claimant, and contributory negligence.

Relationship with nuisance and negligence. Rylands is usually treated as an offshoot of private nuisance and overlaps with negligence. In Transco the House of Lords narrowed the rule but declined to abolish it, keeping it as a distinct strict-liability head for exceptional escapes.

Strict liability for the escape of a dangerous thing — four requirements.
(1) bring/accumulate a dangerous thing; (2) non-natural use (Transco); (3) escape (Read v Lyons); (4) foreseeable damage (Cambridge Water).
'Strict' does not mean automatic — every requirement must be satisfied.
Defences: act of a stranger, act of God, statutory authority, consent, contributory negligence.
Closely linked to nuisance/negligence; narrowed but not abolished (Transco).

Trespass to land — remedies and defences

A direct, intentional intrusion onto land in another's possession — actionable per se, with no need to prove damage.

Trespass to land is a direct and unlawful interference with land in the possession of another. It is the most clear-cut land tort and is contrasted with private nuisance.

Key features:

Direct — the interference must be immediate (walking onto land, placing or throwing objects onto it, driving across it). An INDIRECT interference (noise, smell) is nuisance, not trespass.
Intentional — the act of entering must be deliberate. The defendant need not know the land belongs to someone else; it is enough that they intended the act of entry.
Actionable per se — trespass is actionable without proof of any damage. This makes it a powerful way to protect possession.
Forms — entering land without permission; remaining after permission ends or is withdrawn; placing things on the land; or exceeding the area of any permission given.
Continuing trespass — leaving an object on the land (or remaining on it) is a continuing trespass that gives a fresh cause of action for each day it persists.

Who can sue. The person in possession of the land (not necessarily the owner) may sue.

Remedies:

Damages — compensatory; may be only nominal where no actual loss (because the tort is actionable per se).
Injunction — to restrain a continuing or threatened trespass.
Order for possession — to recover land from a trespasser.
Re-entry — limited self-help to remove a trespasser using no more than reasonable force.

Defences:

Licence / consent — the claimant permitted entry (until the permission is validly withdrawn).
Lawful authority — e.g. a power of entry granted by statute or a court order.
Necessity — entry to prevent a greater harm (narrowly applied).

Trespass to land = a DIRECT, intentional, unlawful interference with land in another's possession.
Actionable per se — no need to prove damage.
Forms include entering, remaining after permission ends, placing objects, or exceeding permission.
Continuing trespass gives a fresh cause of action each day.
Remedies: damages, injunction, order for possession, re-entry.
Defences: licence/consent, lawful authority, necessity.

Quick recap

Classify first: a lawful VISITOR → Occupiers' Liability Act 1957 (s2(2) common duty of care; s2(3)(a) children/allurement; s2(3)(b) skilled visitors; s2(4) warnings/contractors); a TRESPASSER → Occupiers' Liability Act 1984.
OLA 1984 s1(3) imposes a duty to a trespasser only if (a) the occupier is aware of the danger, (b) knows/believes a trespasser may be near, and (c) protection may reasonably be expected; s1(4) duty, s1(5) warnings, and no duty for obvious risks freely accepted (Tomlinson v Congleton BC).
Private nuisance is an unlawful, INDIRECT interference with the enjoyment of land; only a claimant with a proprietary interest can sue (Hunter v Canary Wharf).
Unreasonableness is weighed by locality (Sturges v Bridgman), duration/frequency, abnormal sensitivity (Robinson v Kilvert) and malice (Christie v Davey; Hollywood Silver Fox Farm v Emmett); defences include prescription and statutory authority (Allen v Gulf Oil), but planning permission is NOT a defence; the primary remedy is an injunction.
Rylands v Fletcher is STRICT liability needing all four requirements: bring/accumulate a dangerous thing, non-natural use (Transco), escape (Read v Lyons), and foreseeable damage (Cambridge Water).
Trespass to land is a DIRECT, intentional intrusion, actionable per se (no damage needed), with remedies of damages, injunction and possession.
Authority is non-negotiable: cite the statute SECTION and the leading case for every point, or be capped at Level 2-3.

How it’s examined

This subtopic sits in Topic 4, the Law of Tort, examined on Paper 4 (1h30, 75 marks). Section A offers a choice of two scenario-based problem questions worth 25 marks each — answer ONE using IRAC: identify every tort and party, state the law with the statute section and leading case, apply each element to the facts (classifying visitors vs trespassers, deciding whether a land use is unreasonable, running the Rylands four-part test), deal with defences, and conclude with advice. Section B offers three essays of 25 marks each, of which you answer TWO; the effectiveness of OLA 1984 in protecting trespassers, the workings of private nuisance, and the modern relevance of Rylands v Fletcher are all frequent essay topics requiring a balanced, evaluative judgement. AO weighting across the paper is AO1 50%, AO2 20%, AO3 30%. Practise: (1) the visitor/trespasser classification under time pressure; (2) applying the named sections (not just describing them); and (3) reaching a supported judgement in the evaluative essays.

Step-by-step worked examples — Torts affecting land

Step-by-step solutions to past-paper-style questions on torts affecting land, written exactly the way a tutor would explain them at the board.

1Getting started: classify the claimant — visitor or trespasser?
Getting started• Section A, Occupiers' liability, IRAC, technique
Question
A Paper 4 problem says a person was injured on someone else's land. Before you write anything about a duty of care, you must decide WHICH statute applies. Show how to classify the claimant and pick the right Act.
Step-by-step solution
1. Step 1
  Find the OCCUPIER first. The occupier is the person with control of the premises (Wheat v E Lacon & Co) — usually but not always the owner. There can be more than one occupier. Name them, because the duty is owed BY the occupier.
2. Step 2
  Ask: was the injured person a lawful VISITOR or a TRESPASSER? A lawful visitor has express or implied permission to be there (a customer, a guest, someone with a contractual or statutory right of entry). A trespasser has NO permission, or exceeds the permission given (e.g. goes into a staff-only area, or stays after closing).
3. Step 3
  Map the answer to the correct Act. Lawful visitor → Occupiers' Liability Act 1957. Trespasser (or other non-visitor) → Occupiers' Liability Act 1984. Getting this wrong — applying OLA 1957 to a trespasser — is the single most common and most expensive error on this topic.
4. Step 4
  Watch for a change of status. Permission can have limits of AREA, TIME and PURPOSE. A lawful visitor who wanders into a forbidden part of the premises, or stays after the permitted time, becomes a trespasser ('when you invite a person into your house to use the staircase, you do not invite him to slide down the banisters'). The Act can switch mid-scenario.
5. Step 5
  State your classification as the 'I' (issue) of your IRAC. Write one clear sentence: 'C is a [visitor / trespasser], so the relevant law is OLA [1957 / 1984].' Everything that follows depends on this; make the examiner see you got it right.
Answer
Identify the occupier (control — Wheat v Lacon) → decide visitor (permission) or trespasser (no/exceeded permission) → visitor = OLA 1957, trespasser = OLA 1984 → watch for a change of status by area/time/purpose → state the classification clearly.
Examiner tip
Section A is AO1 + AO2 + AO3. Correct classification is the gateway: apply the wrong Act and the rest of the answer, however fluent, is largely off-point. Always name the Act AND a case (Wheat v Lacon for 'occupier'); section numbers come next.
2Getting started: the IRAC skeleton for a 25-mark land-tort problem
Getting started• Section A, IRAC, structure, technique
Question
Section A gives you a scenario worth 25 marks. Show the IRAC structure that guarantees you state the law, apply it, and conclude — rather than just retelling the facts.
Step-by-step solution
1. Step 1
  I — Issue. Open by spotting EVERY tort the facts raise and naming the parties. A garden scenario might raise occupiers' liability (a guest trips), private nuisance (loud noise next door) AND Rylands v Fletcher (a chemical escapes). Deal with each as a separate IRAC block.
2. Step 2
  R — Rule. State the law with AUTHORITY. For each tort give the source: the statute section (OLA 1957 s2(2); OLA 1984 s1(3)) or the common-law rule (private nuisance = unlawful indirect interference with use/enjoyment of land; Rylands = the four requirements), plus the leading case. No authority = capped at Level 2-3.
3. Step 3
  A — Application. This is where marks are won. Take each element of the rule and tie it to a FACT from the scenario. Do not describe the law in the abstract — say 'here, the danger was the icy step, of which the occupier was aware, so s1(3)(a) OLA 1984 is satisfied because...'.
4. Step 4
  Deal with DEFENCES. A top answer always checks defences: consent / volenti, contributory negligence, warnings, exclusion of liability, and (for nuisance/Rylands) prescription, statutory authority, act of a stranger or act of God. Apply them to the facts too.
5. Step 5
  C — Conclusion. Reach a clear, advised outcome for each party: 'C is likely to succeed against D in [tort] because... but D may reduce damages by pleading contributory negligence.' A confident, fact-based conclusion lifts you into the top band.
Answer
Issue (spot every tort + parties) → Rule (statute section + leading case for each) → Application (each element to a named fact) → Defences → Conclusion (advise the outcome per party). One IRAC block per tort.
Examiner tip
Examiner reports stress that the marks lie in APPLICATION (AO2), not in reciting the law. Candidates who 'write all they know' about OLA without applying it to the scenario stall in the middle bands. IRAC forces application and keeps multi-issue problems organised.
3Building confidence: applying the OLA 1957 common duty of care
Building confidence• Section A, OLA 1957, visitors, technique
Question
A lawful visitor is injured on D's premises. Show how to work through the Occupiers' Liability Act 1957 to a top-band conclusion.
Step-by-step solution
1. Step 1
  State the duty: OLA 1957 s2(2). The occupier owes the common duty of care — to take such care as in all the circumstances is reasonable to see that the visitor is reasonably safe in using the premises FOR THE PURPOSES for which they are invited or permitted to be there. It protects the visitor, not necessarily their property.
2. Step 2
  Check the special categories. Children — s2(3)(a): an occupier must be prepared for children to be less careful than adults. Watch for an ALLUREMENT — something tempting and dangerous (Glasgow Corporation v Taylor — poisonous berries; Jolley v Sutton LBC — an abandoned boat children were bound to play with, the wider danger being foreseeable).
3. Step 3
  Skilled visitors — s2(3)(b): an occupier may expect a person exercising their calling to guard against risks ordinarily incidental to their trade (Roles v Nathan — chimney sweeps killed by carbon-monoxide fumes; the occupier was not liable for the very risk of their job). If the claimant is a tradesperson, this often defeats the claim.
4. Step 4
  Warnings — s2(4)(a): a warning does not discharge the duty unless it was enough to make the visitor reasonably safe. Independent contractors — s2(4)(b): the occupier is NOT liable for a contractor's faulty work if it was reasonable to entrust it to a contractor, the occupier took care to select a competent one, and (where reasonable) checked the work was properly done (Haseldine v Daw — lift repair, a specialist task, occupier not liable).
5. Step 5
  Defences then conclude. Consider consent (volenti — s2(5)), contributory negligence (damages reduced), and any valid exclusion. Then state the outcome: 'The occupier breached s2(2) by [fact], so C succeeds, subject to a possible reduction for contributory negligence.'
Answer
s2(2) common duty of care → child visitors s2(3)(a) (allurement — Glasgow Corp v Taylor; Jolley v Sutton) → skilled visitors s2(3)(b) (Roles v Nathan) → warnings s2(4)(a) / independent contractors s2(4)(b) (Haseldine v Daw) → defences → conclusion.
Examiner tip
AO1 for the sections, AO2 for application, AO3 for evaluating which sub-rule applies. The discriminator is matching the RIGHT sub-section to the facts: a child → s2(3)(a); a workman → s2(3)(b); a contractor's defective work → s2(4)(b). Quote the section number every time.
4Building confidence: assessing UNREASONABLENESS in private nuisance
Building confidence• Section A, Private nuisance, unreasonableness, technique
Question
Two neighbours fall out over noise and smell. Show how to decide whether the interference is an actionable private nuisance by weighing the unreasonableness factors.
Step-by-step solution
1. Step 1
  Define and check standing first. Private nuisance = an unlawful, INDIRECT interference with a person's use or enjoyment of their land. The claimant must have a PROPRIETARY INTEREST in the affected land (an owner or tenant) — Hunter v Canary Wharf; a mere licensee (e.g. a lodger or a family member with no legal interest) cannot sue.
2. Step 2
  Locality / character of the neighbourhood — Sturges v Bridgman: 'what would be a nuisance in Belgrave Square would not necessarily be so in Bermondsey.' Noise or smell tolerable in an industrial area may be a nuisance in a quiet residential one. (Note: this factor does not apply where there is physical DAMAGE to property — only to loss of amenity/enjoyment.)
3. Step 3
  Duration, frequency and time of day: a nuisance is usually continuous or recurrent. A one-off or short-lived interference is less likely to be actionable, while constant or night-time noise weighs in the claimant's favour.
4. Step 4
  Abnormal sensitivity — Robinson v Kilvert: a claimant cannot complain merely because their use is unusually delicate (heat that only damaged exceptionally sensitive brown paper was not a nuisance). The modern approach asks foreseeability of harm to an ordinary use (Network Rail v Morris). Malice — Christie v Davey; Hollywood Silver Fox Farm v Emmett: deliberately spiteful behaviour (banging on the wall; firing a gun to scare breeding foxes) makes otherwise lawful conduct unreasonable.
5. Step 5
  Defences and remedies, then conclude. Defences: prescription (the nuisance continued 20 years), statutory authority (Allen v Gulf Oil) — but NOT planning permission, which is not a defence. Remedies: injunction (the primary remedy), damages, and self-help abatement. Conclude on whether the interference is unreasonable and what C can obtain.
Answer
Define + check proprietary interest (Hunter v Canary Wharf) → locality (Sturges v Bridgman) → duration/frequency → abnormal sensitivity (Robinson v Kilvert) and malice (Christie v Davey; Hollywood Silver Fox Farm) → defences (prescription; statutory authority — Allen v Gulf Oil; planning permission is NOT a defence) + remedies → conclude.
Examiner tip
AO2/AO3 dominate: you must WEIGH the factors against the facts, not just list them. The two most rewarded discriminators are standing (no proprietary interest = no claim, Hunter) and malice (which can tip lawful conduct into a nuisance). Name a case for each factor you use.
5Stretch: running the four-part Rylands v Fletcher test
Stretch• Section A, Rylands v Fletcher, strict liability, technique
Question
Something dangerous stored on D's land escapes and causes damage to C's neighbouring land. Show how to apply the rule in Rylands v Fletcher precisely.
Step-by-step solution
1. Step 1
  Requirement 1 — D brings/accumulates a dangerous thing. D must have BROUGHT onto their land, and accumulated there, something likely to do mischief if it escapes (water, gas, chemicals, fire, electricity). Things naturally present on the land (e.g. naturally growing weeds, naturally accumulating water) are NOT 'brought' and fall outside the rule.
2. Step 2
  Requirement 2 — non-natural use of land. The use must be NON-NATURAL: extraordinary and unusual, not an ordinary use of land (Transco v Stockport MBC — supplying water to a block of flats through a normal pipe was an ordinary, natural use, so no liability). Storing industrial quantities of chemicals or water in bulk is typically non-natural; ordinary domestic use is not.
3. Step 3
  Requirement 3 — the thing ESCAPES. There must be an escape from land the defendant occupies or controls to land outside it. If the dangerous thing injures someone WITHIN D's own land, there is no escape and the rule does not apply (Read v Lyons).
4. Step 4
  Requirement 4 — foreseeable DAMAGE. The escape must cause damage that was a FORESEEABLE type of harm (Cambridge Water Co v Eastern Counties Leather — the chemical's eventual seepage into a borehole was not foreseeable at the time, so liability failed). Liability is STRICT (no need to prove negligence) but the kind of damage must be foreseeable.
5. Step 5
  Check defences, then conclude. Defences: act of a stranger (a third party caused the escape), act of God (extraordinary natural event), statutory authority, consent of the claimant, and contributory negligence. If all four requirements are met and no defence applies, D is strictly liable; conclude on the facts.
Answer
(1) brings/accumulates a dangerous thing → (2) non-natural use (Transco) → (3) it escapes (Read v Lyons) → (4) foreseeable damage (Cambridge Water) → check defences (stranger, act of God, statutory authority, consent, contributory negligence) → conclude on strict liability.
Examiner tip
A* technique: treat the four requirements as a CHECKLIST and apply each to a named fact. The two most commonly missed are 'non-natural use' (Transco) and 'foreseeability of damage' (Cambridge Water) — naming both cases by element is the surest route to the top band. Strict liability does not mean automatic liability: every requirement must still be satisfied.
6Stretch: structuring a 25-mark evaluative essay (Section B)
Stretch• Section B, essay, evaluation, AO3
Question
Section B asks: 'Evaluate the protection that the Occupiers' Liability Act 1984 gives to trespassers.' Build a structure that reaches a supported, evaluative judgement rather than a description of the Act.
Step-by-step solution
1. Step 1
  Introduction — define and frame the debate. Define a trespasser and state that, since OLA 1984, an occupier CAN owe a limited duty to a trespasser (replacing the old 'common humanity' rule). Frame the question: does the 1984 Act strike a fair balance between protecting the careless trespasser and not over-burdening the innocent occupier?
2. Step 2
  Explain the law accurately (AO1). A duty arises only if the three s1(3) conditions are met: (a) the occupier is aware of the danger or has reasonable grounds to believe it exists; (b) knows or has reasonable grounds to believe the trespasser is or may come into the vicinity; (c) the risk is one against which they may reasonably be expected to offer protection. The duty (s1(4)) is to take reasonable care to see the trespasser is not injured by the danger; warnings (s1(5)) may discharge it.
3. Step 3
  Evaluate the STRENGTHS (AO3). The Act gives genuine protection (especially to child trespassers); it imposes a clear three-stage test; warnings can fairly discharge the duty; and it sensibly limits protection to PERSONAL INJURY, not property. Cite that liability is not automatic — the occupier is not an insurer.
4. Step 4
  Evaluate the WEAKNESSES / limits (AO3). Tomlinson v Congleton BC shows the courts will not protect those who freely accept obvious risks — the council owed no duty to a man who dived into a shallow lake despite warning signs, as the danger was obvious and arose from his own free choice. Critics argue this leaves some trespassers unprotected; others argue it rightly preserves personal responsibility and stops occupiers having to 'sanitise' their land.
5. Step 5
  Conclusion — a supported judgement. Commit: e.g. 'OLA 1984 strikes a defensible balance — it protects the genuinely endangered, especially children, while Tomlinson ensures adults who court obvious danger by free choice cannot shift the cost to occupiers. The protection is limited, but deliberately and justifiably so.' Judge against a stated criterion (fair balance), don't sit on the fence.
Answer
Intro (define + frame the balance) → law (s1(3) three conditions; s1(4) duty; s1(5) warnings) → strengths (real protection, esp. children; PI only) → weaknesses (Tomlinson — obvious risk / free will) → criterion-based judgement that commits.
Examiner tip
Section B is heavily AO3 (evaluation) on top of AO1. The top band needs accurate law (s1(3)-(5)), a genuine two-sided evaluation, and a SUSTAINED, supported judgement. Tomlinson v Congleton BC is the essential authority — using it to assess the balance the Act strikes is what separates Level 5 from a descriptive Level 3.

Model Answers — Torts affecting land

High-scoring sample answers for torts affecting land on the Cambridge IGCSE paper, with examiner-style notes mapping each response to the mark scheme and assessment objectives.

Question 1
9084 Paper 4-style single-issue occupiers' liability problem25 marks
[EASY] Mara visits a supermarket and slips on a spillage that staff had known about for an hour but had not cleaned up or signposted. Advise Mara whether she can claim against the supermarket. (Paper 4, Section A, 25 marks)
Model answer
Issue. Mara is injured on the supermarket's premises and seeks to claim. The issue is whether the supermarket, as occupier, is liable under the Occupiers' Liability Act 1957.

Rule. The supermarket is the occupier because it has control of the premises (Wheat v E Lacon & Co). Mara is a lawful visitor — a customer has the shop's implied permission to enter — so the Occupiers' Liability Act 1957 applies (not the 1984 Act, which governs trespassers). Under s2(2) the occupier owes the common duty of care: to take such care as in all the circumstances is reasonable to see that the visitor is reasonably safe in using the premises for the purposes for which she is permitted to be there.

Application. Mara entered for the ordinary purpose of shopping, so she is squarely within the protection of s2(2). The duty is breached if the occupier failed to take reasonable care. Here the staff knew about the spillage for an hour yet neither cleaned it nor put up a warning. A reasonable occupier would have dealt promptly with a known slipping hazard on a shop floor used by the public. As there was no warning under s2(4)(a), the supermarket cannot say it did enough to make Mara reasonably safe. The breach caused her injury, so the duty under s2(2) was breached.

Defences. The supermarket might argue contributory negligence if Mara was not looking where she was going, which would reduce (not defeat) her damages. There is no suggestion of a valid exclusion notice or of consent.

Conclusion. Mara is likely to succeed against the supermarket under OLA 1957 s2(2): it breached the common duty of care by leaving a known spillage unattended and unsignposted. Her damages may be reduced if she was partly at fault.
Why this scores
A clean top-band single-issue answer. It classifies the claimant correctly (visitor → OLA 1957, expressly distinguished from OLA 1984), cites the occupier authority (Wheat v Lacon), states and APPLIES s2(2), notes the absent warning under s2(4)(a), considers a defence, and concludes with advice. Note the explicit visitor/trespasser statement — examiners reward showing you chose the right Act.
Question 2
9084 Paper 4-style discrete essay25 marks
[EASY] Explain the difference between trespass to land and private nuisance, and why the distinction matters. (Paper 4, Section B-style short essay, 25 marks)
Model answer
Introduction. Both trespass to land and private nuisance are torts that protect a person's interest in their land, but they protect against different kinds of interference and have different requirements. Identifying which applies is essential because it changes what the claimant must prove.

Trespass to land. Trespass to land is a direct and unlawful interference with land in the possession of another. It must be intentional (the act of entering must be deliberate, though the trespasser need not know the land belongs to someone else) and direct — for example walking onto land without permission, placing objects on it, or refusing to leave. Crucially, trespass is actionable per se: the claimant need NOT prove any damage. A continuing trespass (such as leaving an object on the land) gives rise to a fresh cause of action each day it remains. The usual remedies are an injunction, damages and an order for possession.

Private nuisance. Private nuisance is an unlawful, INDIRECT interference with a person's use or enjoyment of their land — for example noise, smell, smoke or vibrations crossing from neighbouring land. Unlike trespass, the interference is indirect, the claimant must usually prove some damage or substantial loss of amenity, and the interference must be unreasonable (judged by locality, duration, sensitivity and malice). The claimant must also have a proprietary interest in the affected land (Hunter v Canary Wharf).

Why the distinction matters. The key contrast is direct vs indirect and actionable per se vs requiring proof of unreasonable interference. Throwing rubbish over a fence so it lands on a neighbour's lawn is a direct trespass (actionable even without harm); allowing smoke or smell to drift over is an indirect nuisance (actionable only if unreasonable). Choosing the right tort determines what the claimant must establish and which remedy is available.

Conclusion. Trespass to land guards possession against direct, intentional intrusion and needs no proof of damage; private nuisance guards the use and enjoyment of land against indirect, unreasonable interference and generally requires both unreasonableness and standing. The directness of the interference is the decisive dividing line.
Why this scores
Scores well because it is precise on the defining features (direct/intentional/actionable per se for trespass; indirect/unreasonable/proprietary interest for nuisance), uses a concrete example to show the boundary, and cites Hunter v Canary Wharf. The 'why it matters' section adds the evaluative dimension (AO3) the command word invites.
Question 3
9084 Paper 4-style OLA 1984 trespasser problem25 marks
[MEDIUM] A factory owner knows that local children regularly squeeze through a broken fence to play near an unguarded, deep chemical pit. One child, Sam, falls in and is injured. There are no warning signs. Advise Sam. (Paper 4, Section A, 25 marks)
Model answer
Issue. Sam is injured on the factory owner's land. As Sam had no permission to be there, the issue is whether the owner owes him a duty as a trespasser under the Occupiers' Liability Act 1984.

Rule. The factory owner is the occupier with control of the premises (Wheat v E Lacon & Co). Sam squeezed through the fence without permission, so he is a trespasser and the 1984 Act, not the 1957 Act, applies. Under s1(3) an occupier owes a duty to a trespasser only if THREE conditions are met: (a) the occupier is aware of the danger or has reasonable grounds to believe it exists; (b) the occupier knows or has reasonable grounds to believe the trespasser is or may come into the vicinity of the danger; and (c) the risk is one against which, in all the circumstances, the occupier may reasonably be expected to offer some protection. If a duty arises, s1(4) requires reasonable care to see the trespasser is not injured by the danger, and under s1(5) the duty may be discharged by giving warning of the danger.

Application. Applying s1(3): (a) the owner is aware of the danger — an unguarded, deep chemical pit is plainly dangerous and known to exist; (b) the owner knows children regularly come into the vicinity through the broken fence, so the second condition is satisfied; (c) given that the danger is severe, the victims are likely to be children, and protection (fencing or filling the pit) was readily available, this is a risk against which the owner may reasonably be expected to offer protection. All three s1(3) conditions are met, so a duty is owed. Under s1(4) the owner failed to take reasonable care — the pit was unguarded — and under s1(5) there were no warning signs, so the duty was not discharged.

Defences. Unlike the adult in Tomlinson v Congleton BC, who freely accepted an obvious risk, Sam is a child who is unlikely to appreciate the danger, so the 'free will / obvious risk' reasoning will not assist the owner. There is no realistic consent, and limited scope for contributory negligence given Sam's age.

Conclusion. All three s1(3) conditions being satisfied, the factory owner owes Sam a duty under the OLA 1984, breached it under s1(4) by leaving the pit unguarded with no warning, and is therefore likely to be liable for Sam's injuries.
Why this scores
A strong Level 4/5 answer: it correctly routes a trespasser to OLA 1984 (not 1957), works methodically through ALL THREE s1(3) conditions applying each to a fact, addresses s1(4) and s1(5), and uses Tomlinson v Congleton BC to distinguish a child from the obvious-risk adult. The section-by-section application is exactly what the mark scheme rewards.
Question 4
9084 Paper 4-style private nuisance problem25 marks
[MEDIUM] Tom, who owns his house in a quiet residential street, is disturbed every night by loud music from Dev's new recording studio next door. After Tom complains, Dev deliberately turns the volume even higher to annoy him. Advise Tom. (Paper 4, Section A, 25 marks)
Model answer
Issue. Tom is disturbed by noise from Dev's land. The issue is whether this is an actionable private nuisance.

Rule. Private nuisance is an unlawful, indirect interference with a person's use or enjoyment of their land. The claimant must have a proprietary interest in the affected land (Hunter v Canary Wharf). The interference must be unreasonable, assessed by factors including the locality / character of the neighbourhood (Sturges v Bridgman), the duration and frequency of the interference, the claimant's abnormal sensitivity (Robinson v Kilvert), and malice (Christie v Davey; Hollywood Silver Fox Farm v Emmett).

Application. Tom owns his house, so he has the proprietary interest required by Hunter v Canary Wharf and can sue. The interference is indirect (noise crossing the boundary), satisfying the basic definition. On unreasonableness: (i) locality — this is a quiet residential street, where, as Sturges v Bridgman shows, what would be tolerated in an industrial area may well be a nuisance; (ii) duration/frequency — the music is every night, i.e. continuous and at an unsociable time, which strongly supports a nuisance; (iii) there is no abnormal sensitivity — Tom is an ordinary householder, not unusually delicate as in Robinson v Kilvert. Decisively, after Tom complained Dev deliberately increased the volume to annoy him: this is malice, and on the authority of Christie v Davey (deliberate banging in retaliation) and Hollywood Silver Fox Farm v Emmett (firing a gun to spite a neighbour) malice makes otherwise borderline conduct unreasonable.

Defences. Dev cannot rely on prescription (the studio is new, nowhere near 20 years). He has no statutory authority (Allen v Gulf Oil), and any planning permission for the studio is not a defence to nuisance. 'Coming to the nuisance' is also no defence.

Remedies and conclusion. Tom is likely to succeed in private nuisance: he has standing, the interference is indirect, and it is unreasonable given the residential locality, the nightly duration and — above all — Dev's malice. The primary remedy is an injunction to restrain the excessive noise, with damages for the disturbance suffered.
Why this scores
Top-band private nuisance: it confirms standing (Hunter), weighs each unreasonableness factor against a named fact, and correctly identifies malice (Christie v Davey; Hollywood Silver Fox Farm v Emmett) as the decisive element. It also nails two examiner favourites — that planning permission is NOT a defence, and that the primary remedy is an injunction.
Question 5
9084 Paper 4-style multi-issue land-torts problem (A* exemplar)25 marks
[HARD] Greenfield Ltd runs a chemical works on an industrial estate. (1) A delivery driver, Raj, slips on a patch of oil in the loading bay that supervisors knew about; (2) Greenfield stores large tanks of industrial solvent, one of which bursts, and the solvent escapes onto neighbouring farmland owned by Nadia, poisoning her crops; (3) the works also emits a strong chemical smell that drifts into Nadia's farmhouse. Advise Raj and Nadia. (Paper 4, Section A, 25 marks)
Model answer
This scenario raises THREE issues, dealt with in turn: (1) occupiers' liability to Raj; (2) Rylands v Fletcher for the escaped solvent; and (3) private nuisance for the smell.

Issue 1 — Occupiers' liability to Raj. Rule. Greenfield is the occupier with control of the works (Wheat v E Lacon & Co). Raj, a delivery driver with implied permission to be in the loading bay, is a lawful visitor, so the Occupiers' Liability Act 1957 applies and under s2(2) Greenfield owes the common duty of care. Application. Supervisors knew about the oil yet did nothing; a reasonable occupier would have cleared or signed a known slipping hazard, and there was no warning under s2(4)(a). As a delivery driver, Raj is not guarding against a special risk of his calling under s2(3)(b) — slipping on spilled oil is not a risk ordinarily incidental to driving — so that subsection does not help Greenfield. Conclusion. Greenfield breached s2(2); Raj is likely to succeed, subject to any contributory negligence if he failed to take care.

Issue 2 — Rylands v Fletcher (the escaped solvent). Rule. Liability under Rylands v Fletcher is strict and requires: (1) D brings/accumulates a dangerous thing; (2) a non-natural use of land (Transco v Stockport MBC); (3) the thing escapes; and (4) the escape causes foreseeable damage (Cambridge Water Co v Eastern Counties Leather). Application. (1) Greenfield brought and accumulated large tanks of solvent, plainly likely to do mischief if it escapes; (2) storing bulk industrial solvent is an extraordinary and unusual use of land — non-natural within Transco; (3) the solvent escaped onto Nadia's farmland (a true escape beyond Greenfield's land — contrast Read v Lyons); (4) poisoning of neighbouring crops by escaping solvent is a foreseeable type of damage (unlike the unforeseeable seepage in Cambridge Water). All four requirements are satisfied. Defences. No suggestion of act of a stranger, act of God, statutory authority or consent. Conclusion. Greenfield is strictly liable to Nadia under Rylands v Fletcher for the damage to her crops.

Issue 3 — Private nuisance (the smell). Rule. Private nuisance is an unlawful, indirect interference with use/enjoyment of land; the claimant needs a proprietary interest (Hunter v Canary Wharf) and the interference must be unreasonable (locality — Sturges v Bridgman; duration; sensitivity — Robinson v Kilvert; malice). Application. Nadia owns the farmhouse, so she has standing. The smell is an indirect interference. On locality, this is an industrial estate, which (per Sturges v Bridgman) makes some smell more tolerable; but a strong chemical smell drifting persistently into a home may still be unreasonable depending on its strength and frequency. There is no abnormal sensitivity and no malice. Defences. Any planning permission for the works is not a defence; if the activity is authorised by statute, Allen v Gulf Oil could assist Greenfield, but there is no evidence of that here. Conclusion. Nadia may succeed in private nuisance over the smell if it is shown to be sufficiently strong and persistent to be unreasonable despite the industrial locality; the remedy would be an injunction and/or damages.

Overall. Raj is likely to recover under OLA 1957 s2(2); Nadia is likely to recover under Rylands v Fletcher for the crops and may recover in private nuisance for the smell.
Why this scores
A* multi-issue control. It separates three torts into clean IRAC blocks, routes the visitor correctly to OLA 1957 (with s2(3)(b) considered and rejected), runs ALL FOUR Rylands requirements each against a fact (Transco for non-natural use, Read v Lyons for escape, Cambridge Water for foreseeable damage), and handles nuisance with locality balanced against the residential intrusion. Every element carries a section number or named case — the cap rule is comfortably cleared.
Question 6
9084 Paper 4-style evaluative essay (A* exemplar)25 marks
[HARD] 'The rule in Rylands v Fletcher is now of little practical relevance.' Evaluate this statement. (Paper 4, Section B, 25 marks)
Model answer
Introduction. The rule in Rylands v Fletcher (1868) imposes strict liability for the escape of a dangerous thing from a non-natural use of land. This essay evaluates whether the rule retains practical importance, judging 'relevance' by whether it still provides claimants with a distinct and useful cause of action. It argues the rule survives but in a narrowed, residual form.

The requirements (AO1). Liability requires: (1) the defendant brings/accumulates something likely to do mischief if it escapes; (2) a non-natural use of land; (3) an escape; and (4) foreseeable damage of the relevant type. The leading modern authorities have shaped each element.

The case that the rule is of little relevance. Several developments have shrunk the rule. First, foreseeability of harm is now required: in Cambridge Water Co v Eastern Counties Leather the House of Lords held that liability does not arise unless the type of damage was foreseeable, bringing the rule much closer to negligence and removing its purely 'strict' edge. Secondly, the non-natural use requirement has been narrowed: in Transco v Stockport MBC the court held that the use must be extraordinary and unusual, so many ordinary industrial and domestic activities fall outside the rule altogether (piping water to flats was natural). Thirdly, the numerous defences (act of a stranger, act of God, statutory authority, consent, contributory negligence) make claims hard to win. Fourthly, the rule overlaps heavily with private nuisance (of which it is often treated as an offshoot) and with negligence, so claimants frequently have an easier alternative. Other jurisdictions have even abolished the rule, treating it as absorbed into negligence.

The case that the rule remains relevant. Yet the rule has NOT been abolished in England and Wales. In Transco the House of Lords expressly declined to abolish it, preferring to retain it as a distinct head of liability for exceptional cases. It still offers a real advantage: it is strict, so a claimant need not prove negligence — valuable where a dangerous escape occurs without provable fault, for example from the bulk storage of hazardous substances. It therefore fills a gap for isolated escapes that nuisance (which usually requires a continuing state of affairs) may not cover. The rule also expresses an important policy: those who, for their own purposes, accumulate exceptionally dangerous things on their land should bear the risk if they escape.

Judgement. The statement is partly true. Cambridge Water and Transco have so narrowed the rule — through the foreseeability requirement and the demanding 'non-natural use' test — that successful claims are now rare and many situations are better pursued in negligence or nuisance. To that extent its PRACTICAL use is limited. However, 'little relevance' overstates the position: the courts have deliberately preserved the rule as a distinct, strict-liability cause of action for exceptional escapes of dangerous things, and it retains real value where fault cannot be proved. The better view is that Rylands v Fletcher is now a narrow but still living rule — much diminished in scope, yet not redundant.
Why this scores
A genuine Level 5 essay. It states the four requirements accurately (AO1), then evaluates BOTH sides with the two pivotal cases (Cambridge Water on foreseeability; Transco on non-natural use and on the refusal to abolish), weighs overlap with nuisance/negligence and the strict-liability advantage, and reaches a SUSTAINED, criterion-based judgement ('narrow but still living'). The balanced AO3 analysis plus authority is what lifts it above a one-sided 'it's obsolete' answer.

Key Definitions and Keywords — Torts affecting land

Definitions to memorise and the exact keywords mark schemes credit for torts affecting land answers — sharpened from recent examiner reports for the 2026 Cambridge IGCSE sitting.

Occupier
Examiner keyword
The person who has a sufficient degree of control over premises to put them under a duty of care to those who come onto them. It is based on control, not ownership, and there can be more than one occupier.
Example
Wheat v E Lacon & Co — both a brewery and the manager were occupiers of a pub.
Lawful visitor
Examiner keyword
A person who has express or implied permission, or a legal/contractual right, to be on the premises. Visitors are protected by the Occupiers' Liability Act 1957.
Example
A customer in a shop, an invited guest, a postal worker delivering mail.
Trespasser
Examiner keyword
A person who enters or remains on land without any permission, or who exceeds the permission given. Trespassers are owed only the limited duty under the Occupiers' Liability Act 1984.
Example
Someone climbing over a fence, or a visitor who enters a 'staff only' area.
Common duty of care (OLA 1957 s2(2))
Examiner keyword
The duty an occupier owes to lawful visitors: to take such care as in all the circumstances is reasonable to see that the visitor will be reasonably safe in using the premises for the purposes for which they are permitted to be there.
Allurement
Examiner keyword
Something on the premises that is both tempting and dangerous to a child. Its presence raises the standard of care owed to child visitors under OLA 1957 s2(3)(a).
Example
Glasgow Corporation v Taylor — attractive but poisonous berries; Jolley v Sutton LBC — an abandoned boat.
Independent contractor (OLA 1957 s2(4)(b))
Examiner keyword
A person engaged to do work on the premises. An occupier is generally not liable for the contractor's faulty work if it was reasonable to entrust the task to a contractor, a competent one was chosen, and (where reasonable) the work was checked.
Example
Haseldine v Daw — lift repair was a specialist task, so the occupier was not liable.
Private nuisance
Examiner keyword
An unlawful, indirect interference with a person's use or enjoyment of their land (e.g. by noise, smell, smoke or vibration). It must be unreasonable to be actionable.
Unreasonable interference
Examiner keyword
The threshold for private nuisance, judged by weighing factors such as the locality, the duration and frequency of the interference, the claimant's sensitivity, and any malice.
Locality (character of the neighbourhood)
Examiner keyword
A factor in deciding unreasonableness: an interference acceptable in one area may be a nuisance in another. It applies to loss of amenity, not to physical damage to property.
Example
Sturges v Bridgman — 'what would be a nuisance in Belgrave Square would not necessarily be so in Bermondsey'.
Abnormal sensitivity
Examiner keyword
A claimant cannot complain of a nuisance merely because their property or use of land is unusually delicate; the test looks at interference with ordinary use.
Example
Robinson v Kilvert — heat that damaged only exceptionally sensitive brown paper was not a nuisance.
Malice
Examiner keyword
Deliberate, spiteful conduct intended to annoy the claimant. Malice can make otherwise lawful or borderline conduct unreasonable and therefore an actionable nuisance.
Example
Christie v Davey — retaliatory banging; Hollywood Silver Fox Farm v Emmett — firing a gun to disturb breeding foxes.
Proprietary interest
Examiner keyword
A legal interest in the affected land (such as ownership or a tenancy) which a claimant must have in order to sue in private nuisance. A mere licensee cannot sue.
Example
Hunter v Canary Wharf — family members with no legal interest in the home could not sue.
Rule in Rylands v Fletcher
Examiner keyword
Strict liability where a person brings and accumulates on their land a dangerous thing, makes a non-natural use of the land, and the thing escapes and causes foreseeable damage.
Non-natural use of land
Examiner keyword
A requirement of Rylands v Fletcher: the defendant's use of land must be extraordinary and unusual, not an ordinary use of land.
Example
Transco v Stockport MBC — supplying water to flats through a normal pipe was an ordinary (natural) use.
Escape
Examiner keyword
A requirement of Rylands v Fletcher: the dangerous thing must escape from land the defendant occupies or controls to land outside it. There is no liability if the harm occurs within the defendant's own land.
Example
Read v Lyons — an explosion inside a factory was no 'escape', so the rule did not apply.
Strict liability
Examiner keyword
Liability that does not depend on proving fault or negligence. Rylands v Fletcher imposes strict liability, though the four requirements (including foreseeable damage) must still be satisfied.
Trespass to land
Examiner keyword
A direct and unlawful interference with land in the possession of another. It must be intentional and is actionable per se (without proof of damage).
Actionable per se
Examiner keyword
A tort that is actionable in itself, without the claimant having to prove that any damage was suffered. Trespass to land is actionable per se.

Common Mistakes and Misconceptions — Torts affecting land

The traps other students keep falling into on torts affecting land questions — taken from recent Cambridge IGCSE examiner reports and mark schemes — and how to avoid them.

✕Applying the Occupiers' Liability Act 1957 to a trespasser (or the 1984 Act to a lawful visitor)
9084 Paper 4 Examiner Reports — Law of Tort
Why it happens
Students learn the two Acts together and grab the more familiar 1957 Act without first classifying the claimant.
How to avoid it
ALWAYS classify the claimant first. Lawful visitor (permission) → OLA 1957; trespasser (no/exceeded permission) → OLA 1984. State your classification in one sentence before doing anything else, and watch for a change of status by area, time or purpose.
✕Confusing private nuisance (indirect interference) with trespass to land (direct interference)
9084 Paper 4 Examiner Reports — Law of Tort
Why it happens
Both protect interests in land, so students treat any interference as 'a nuisance' or 'a trespass' without analysing how the interference occurs.
How to avoid it
Ask: is the interference DIRECT (walking on/placing something on the land = trespass, actionable per se) or INDIRECT (noise/smell/smoke drifting across = private nuisance, requiring unreasonableness)? Directness is the dividing line.
✕Forgetting the Rylands requirements of NON-NATURAL use and a genuine ESCAPE
Transco v Stockport MBC; Read v Lyons; Cambridge Water Co v Eastern Counties Leather
Why it happens
Students remember 'a dangerous thing causes harm' but skip the two filtering requirements that actually decide most cases.
How to avoid it
Run all FOUR requirements as a checklist: (1) brings/accumulates a dangerous thing; (2) non-natural use — extraordinary/unusual (Transco); (3) it ESCAPES beyond D's land (Read v Lyons); (4) foreseeable damage (Cambridge Water). Apply each to a fact.
✕Allowing a claimant with no proprietary interest to sue in private nuisance
Hunter v Canary Wharf [1997]
Why it happens
Students focus on whether someone is annoyed and forget that nuisance protects an interest in LAND, not the person.
How to avoid it
Check standing first: only a person with a proprietary interest (owner or tenant) can sue in private nuisance (Hunter v Canary Wharf). A lodger, guest or family member with no legal interest cannot. State this before assessing unreasonableness.
✕Describing the law in the abstract instead of APPLYING the section/case to the facts
9084 Paper 4 Examiner Reports — 'apply the law to the scenario'
Why it happens
Students revise the rules thoroughly and want to show their knowledge by 'writing all they know' in a Section A problem.
How to avoid it
Use IRAC and tie every element of the rule to a specific fact: 'here, the occupier KNEW children came through the broken fence, so s1(3)(b) OLA 1984 is satisfied.' Application (AO2) is where the marks are; pure description stalls in the middle bands.
✕Failing to cite the statute SECTION number AND a leading case (the cap rule)
9084 Paper 4 mark scheme — authority requirement
Why it happens
Students state the rule correctly in their own words but omit the authority, assuming the substance is enough.
How to avoid it
Name the authority every time: OLA 1957 s2(2); OLA 1984 s1(3); plus the case (Wheat v Lacon, Glasgow Corp v Taylor, Tomlinson, Sturges v Bridgman, Rylands, Cambridge Water, Transco...). Without sections + cases an answer is capped around Level 2-3.
