Revision Notes 📚
Comparing torts connected to land A-Level Law revision overview
OCR groups private nuisance and Rylands v Fletcher together as torts connected to land. The specification requires:
the basic elements of private nuisance
who can claim
what amounts to a nuisance
unreasonable interference
who may be sued
private nuisance defences and remedies
the definition and requirements of Rylands v Fletcher
defences available to a Rylands v Fletcher claim.
The two torts are connected, but they are not interchangeable.
A strong problem answer therefore begins by asking:
What exactly has happened to the claimant's land?
The answer to that question often points towards the correct tort.
The basic difference
At its simplest:
Private nuisance focuses on an unlawful and indirect interference with another person's use or enjoyment of land or rights over it.
Rylands v Fletcher focuses on something that the defendant has brought onto and accumulated on land, which is likely to cause mischief if it escapes, where the use is extraordinary and unusual and the thing actually escapes causing reasonably foreseeable actionable harm.
A useful starting comparison is:
Private nuisance | Rylands v Fletcher |
Concerned with indirect interference with land or its use and enjoyment. | Concerned with an accumulated thing escaping from the defendant's control. |
Often involves noise, vibrations, smoke, fumes, smells or physical damage. | Requires something to be brought onto and accumulated on land. |
Interference must be unreasonable where the claim concerns use and enjoyment. | Use of land must be extraordinary and unusual in the circumstances of the time and place. |
No separate Rylands-style accumulation requirement. | Requires bringing onto and accumulation. |
No Rylands-style escape requirement. | The thing itself must escape from the defendant's control to the claimant's land. |
Relevant factors include locality, duration and sensitivity. | Relevant requirements include likelihood of mischief, extraordinary use, escape and foreseeable harm. |
This is why learning each tort as a separate legal structure matters.
The relationship between the torts
OCR's 2024 mark scheme describes an action in Rylands v Fletcher as a species of nuisance.
This helps explain why the two actions share features connected with land.
However, Rylands v Fletcher has additional requirements of its own.
You should therefore avoid reasoning:
"Rylands is connected with nuisance, so all the private nuisance rules apply."
They do not.
Instead, use the specific elements required by the tort raised by the facts.
Comparison 1: the claimant
There is an important similarity between the two actions.
Private nuisance
The claimant must have an interest in the affected land.
Hunter v Canary Wharf is the key authority.
This principle was covered in private nuisance: basic elements [Lesson 126. Private nuisance: basic elements].
Rylands v Fletcher
The claimant must also have the relevant legal interest in the land affected by the escape.
OCR mark schemes expressly use Hunter v Canary Wharf when establishing the parties in a Rylands v Fletcher action.
Comparison
Private nuisance | Rylands v Fletcher | |
Must claimant have an interest in the affected land? | Yes | Yes |
Key authority | Hunter v Canary Wharf | Hunter v Canary Wharf |
Main focus | Land affected by the interference | Land affected by the escape |
📌 Exam technique: In either tort, identify the claimant's interest in the land early in your answer.
Comparison 2: the defendant
The position of the defendant is different.
Private nuisance
A potential defendant may be an occupier of the land from which the nuisance originates.
Tetley v Chitty is relevant to occupation, control and possession.
However, the person who causes the nuisance does not necessarily need to have an interest in the land. Thomas v NUM illustrates this principle.
This is developed in unreasonable interference [Lesson 127. Unreasonable interference].
Rylands v Fletcher
The defendant must have the required control and possession of the land or circumstances from which the accumulated thing escapes.
OCR materials identify Read v Lyons in connection with control and the escape requirement.
Comparison
Private nuisance can therefore focus more directly on the person responsible for the nuisance, even where that person does not have a proprietary interest in the land.
Rylands v Fletcher places particular importance on the defendant's control of the land or circumstances from which the thing escapes.
Comparison 3: the nature of the interference
Private nuisance
Private nuisance requires an indirect interference.
Examples recognised in OCR materials include:
noise or vibrations
smoke and fumes
smells
heat
physical damage.
The focus is upon the effect on the claimant's:
land
rights over the land
use or enjoyment of the land.
Rylands v Fletcher
The focus is narrower.
There must be a thing which:
is brought onto the defendant's land
is accumulated there
is likely to cause mischief if it escapes
actually escapes.
The thing itself must escape from land or circumstances controlled by the defendant to land controlled by the claimant. OCR identifies Read v Lyons, Hale v Jennings Bros and Stannard v Gore in connection with the escape requirement.
A crucial distinction: interference and escape
Private nuisance does not require you to prove the specific Rylands concept of escape.
For example:
Machinery next door creates loud noise which travels into the claimant's house every night.
This can point towards private nuisance.
There is no need to identify a stored thing that has escaped.
Compare:
A tank of chemical stored on neighbouring land breaks and the chemical flows across the boundary, destroying the claimant's plants.
These facts strongly point towards Rylands v Fletcher because there is:
accumulation
a potentially harmful thing
movement across the boundary
property damage.
Comparison 4: accumulation
This is one of the quickest ways to distinguish the torts.
Private nuisance
There is no requirement that the defendant must have brought something onto and accumulated it on the land.
A nuisance may arise from activities such as repeated noise or smells without anything being stored.
Rylands v Fletcher
Bringing onto and accumulating is a central requirement.
Giles v Walker is an important authority.
OCR's 2023 mark scheme explains that the defendant must bring onto and accumulate something on land under their control.
Exam trigger
If a scenario repeatedly tells you that the defendant:
brought containers onto land
stored large amounts of a substance
kept a large tank
accumulated oil, chemicals or another substance
you should immediately consider whether Rylands v Fletcher is being raised.
That does not automatically establish liability, but it points you towards the correct legal structure.
Comparison 5: unreasonable interference and extraordinary use
These two ideas can sound similar but must not be merged.
Private nuisance: unreasonable interference
For private nuisance, the question is whether the indirect interference is legally unreasonable.
Relevant considerations include:
locality
duration
sensitivity
malice where supported by the facts.
These are covered fully in unreasonable interference [Lesson 127. Unreasonable interference].
For example:
A furnace produces smoke every night on a quiet residential estate.
Relevant analysis includes:
the residential locality
repeated nighttime duration
whether ordinary use is affected
whether any particular loss results only from unusual sensitivity.
OCR's 2023 private nuisance question specifically required application of locality, duration and sensitivity.
Rylands v Fletcher: extraordinary and unusual use
Rylands v Fletcher instead requires the defendant's use of the land to be extraordinary and unusual having regard to the circumstances of the time and place.
The key authority is Transco v Stockport MBC.
For example:
A farmer uses the farmyard to restore a large yacht and accumulates large quantities of toxic marine varnish.
The issue is whether using farmland in that particular way amounts to an extraordinary and unusual use.
OCR's 2024 mark scheme treated the fact that the location was a farmyard rather than a shipyard, together with the nature and quantity of the varnish, as relevant to this requirement.
Do not interchange the tests
Do not write in a Rylands v Fletcher answer:
"The use is unreasonable because it lasts every night."
That is private nuisance reasoning.
Do not write in a private nuisance answer:
"The defendant's noise is an extraordinary and unusual use under Transco."
That imports the Rylands test.
Keep the structures separate.
Comparison 6: locality
There is an interesting overlap in the importance of location.
In private nuisance
Locality is directly relevant to determining whether interference is unreasonable.
For example, a level of noise that may be expected in an industrial area could be unreasonable in a quiet residential area.
Sturges v Bridgman and Coventry v Lawrence are relevant.
In Rylands v Fletcher
The circumstances of the time and place matter when deciding whether the defendant's use of land is extraordinary and unusual under Transco v Stockport MBC.
The legal questions are still different:
Private nuisance: Is the interference unreasonable in this locality?
Rylands: Is this use of land extraordinary and unusual in the circumstances of this time and place?
That distinction can gain valuable precision in AO1 and AO2.
Comparison 7: duration
Private nuisance
Duration and frequency can be central to establishing unreasonable interference.
A repeated disturbance can become actionable even if it has not existed for many years.
Relevant authority includes De Keyser's Royal Hotel Ltd v Spicer Bros.
Rylands v Fletcher
Duration is not one of the basic Rylands requirements.
The important questions are instead whether the thing:
was accumulated
was likely to cause mischief
was connected with an extraordinary and unusual use
escaped
caused reasonably foreseeable actionable harm.
If a chemical tank bursts once and destroys neighbouring property, the fact that the event happened only once does not mean you should apply private nuisance's duration test to the Rylands claim.
Comparison 8: sensitivity
Private nuisance
The claimant's unusual sensitivity can affect whether an interference is actionable.
Authorities include:
Robinson v Kilvert
McKinnon Industries v Walker
Network Rail Infrastructure Ltd v CJ Morris.
Rylands v Fletcher
Do not automatically import the private nuisance sensitivity rules.
The Rylands question focuses instead on:
reasonable foreseeability of the relevant damage
whether the harm is of an actionable type.
Cambridge Water v Eastern Counties Leather is central to reasonable foreseeability.
This is another example of why the tort must be selected before applying legal principles.
Comparison 9: damage
Private nuisance
Private nuisance can involve:
physical damage, or
interference with the claimant's use and enjoyment of land.
Halsey v Esso Petroleum illustrates this distinction.
A claimant therefore does not necessarily need to show that property has physically been destroyed.
Repeated noise that unreasonably prevents ordinary enjoyment of a house can be sufficient.
Rylands v Fletcher
The escape must cause reasonably foreseeable actionable harm connected with the claimant's rights and enjoyment of land.
Property damage is a clear example.
Importantly:
personal injury is not recoverable in Rylands v Fletcher.
OCR's 2024 mark scheme expressly states that the claimant cannot recover in Rylands for personal injury or death.
Example
Suppose toxic liquid escapes from D's land.
It:
destroys C's strawberry crop
gives C severe headaches.
Under Rylands v Fletcher:
the crop damage may be actionable
the headaches are personal injury and are not recoverable.
OCR used this distinction in the 2024 examination.
A powerful selection clue
If the main complaint is:
"I cannot sleep because of the noise or fumes."
think strongly about private nuisance.
If the main complaint is:
"A substance accumulated next door escaped and destroyed my property."
think strongly about Rylands v Fletcher.
Comparison 10: reasonable foreseeability
Reasonable foreseeability appears prominently in Rylands v Fletcher.
Cambridge Water v Eastern Counties Leather establishes that the relevant type of damage caused by the escape must be reasonably foreseeable.
OCR examiners have warned students not to merge:
the question of whether the thing is likely to do mischief if it escapes, and
whether the actual escape caused reasonably foreseeable harm.
Private nuisance has its own reasonableness analysis, so do not simply transplant the Rylands foreseeability requirement into every nuisance issue.
How to select the appropriate tort
Step 1: identify what has happened
Ask:
Is this primarily a continuing or repeated interference with the claimant's use or enjoyment of land?
If yes, consider private nuisance.
Ask:
Has something been brought onto and accumulated on D's land and then escaped onto C's land?
If yes, consider Rylands v Fletcher.
Step 2: look for factual triggers
Scenario clue | Likely tort to consider |
Repeated nighttime noise | Private nuisance |
Smoke or fumes regularly drifting over neighbouring land | Private nuisance |
Persistent smells affecting use of a house | Private nuisance |
Vibrations from machinery | Private nuisance |
Large tank of chemical stored on land | Rylands v Fletcher |
Hundreds of containers accumulated | Rylands v Fletcher |
Substance crosses the boundary after a leak | Rylands v Fletcher |
Escape destroys crops or plants | Rylands v Fletcher |
Claimant cannot sleep due to repeated activity | Private nuisance |
One accumulated substance escapes and causes foreseeable property harm | Rylands v Fletcher |
This is a selection guide, not a substitute for applying the legal requirements.
Step 3: use the correct legal structure
Once you have selected private nuisance, apply:
claimant's interest in land
indirect interference
physical damage or interference with use and enjoyment
unreasonable interference
relevant factors such as locality, duration and sensitivity
appropriate defendant
any relevant defence.
Once you have selected Rylands v Fletcher, apply:
parties and control of land
bringing onto and accumulation
something likely to do mischief if it escapes
extraordinary and unusual use
escape of the thing itself
reasonably foreseeable damage
actionable harm
any relevant defence.
Step 4: do not force every fact into both torts
OCR examiner reports repeatedly warn against a shotgun approach, where students write everything they know about a broad topic even when it is not relevant.
The same principle should guide tort selection.
If a scenario clearly focuses on:
regular smoke
locality
nighttime disturbance
sensitivity
do not spend half the answer reciting every Rylands v Fletcher element unless the facts genuinely raise them.
Likewise, if the problem centres on:
a stored substance
accumulation
escape
property damage
do not replace Rylands analysis with a lengthy discussion of locality and duration.
Comparing the requirements side by side
Issue | Private nuisance | Rylands v Fletcher |
Land-based tort? | Yes | Yes |
Claimant needs interest in affected land? | Yes, Hunter v Canary Wharf | Yes, Hunter v Canary Wharf |
Defendant's relationship with land | Occupier may be liable, but person causing nuisance need not always have interest in land | Defendant must have relevant control and possession of land or circumstances from which escape occurs |
Indirect interference? | Required | Escape is specifically required |
Bringing onto land? | Not a separate requirement | Required |
Accumulation? | Not a separate requirement | Required, Giles v Walker |
Thing likely to cause mischief? | Not a separate requirement | Required, Hale v Jennings Bros |
Unreasonable interference? | Central requirement | Do not substitute this for Rylands elements |
Locality? | Relevant to unreasonable interference | Time and place relevant to extraordinary and unusual use |
Duration? | Relevant | Not a separate basic requirement |
Sensitivity? | May be relevant | Do not substitute for foreseeability requirement |
Extraordinary and unusual use? | Not the private nuisance test | Required, Transco v Stockport MBC |
Escape? | No separate Rylands-style requirement | Required |
Foreseeability of damage? | Apply relevant nuisance principles | Express Rylands requirement, Cambridge Water |
Personal injury recoverable under the land tort itself? | Focus of private nuisance is interests in land | No, Transco v Stockport MBC |
Comparing the defences
Private nuisance defences
The principal private nuisance defences covered in private nuisance: defences and remedies [Lesson 128. Private nuisance: defences and remedies] include:
statutory authority
prescription.
OCR also requires students to recognise arguments which are not defences, including:
coming to the nuisance
social utility or public benefit.
Planning permission alone does not defeat an actionable nuisance.
Rylands v Fletcher defences
The defences covered in Rylands v Fletcher defences [Lesson 130. Rylands v Fletcher defences] include:
act of a stranger
act of God
volenti non fit injuria
common benefit
damage caused through the claimant's fault.
Defence comparison table
Defence or argument | Private nuisance | Rylands v Fletcher |
Statutory authority | ✓ Available where requirements are satisfied | Do not substitute for the specified Rylands defences in this comparison |
Prescription | ✓ Available after the required actionable nuisance period | Not one of the specific Rylands defences identified in OCR materials |
Coming to the nuisance | ✗ Not a defence | Not a Rylands defence identified here |
Social utility/public benefit | ✗ Not a defence | Not the same as the Rylands common-benefit defence |
Act of a stranger | Not one of the specific private nuisance defences studied here | ✓ |
Act of God | Not one of the specific private nuisance defences studied here | ✓ |
Volenti | Covered as a general tort defence and relevant to Rylands | ✓ |
Common benefit | Do not confuse with public benefit in nuisance | ✓ |
Claimant's fault | Do not automatically import it as a private nuisance-specific defence | ✓ |
The general operation of volenti and the land-specific defences is consolidated later in [Lesson 139. Volenti and land-specific defences].
Common benefit is not social utility
This is an especially useful comparison.
Private nuisance: social utility
The defendant may argue:
"My activity benefits lots of people."
That is social utility or public benefit.
It is not a defence to an established private nuisance.
Rylands: common benefit
The relevant Rylands defence concerns the common benefit of the parties.
This is not simply an argument that the defendant's activity is socially useful.
⚠️ Do not merge these concepts because both contain the word "benefit".
Comparing two similar scenarios
Scenario A
Zara owns a house on a quiet residential estate. The neighbouring workshop operates machinery every night until 2 am. The machinery produces noise and vibrations which repeatedly prevent Zara from sleeping.
The stronger tort is private nuisance.
Why?
Zara's use and enjoyment of land is affected.
Noise and vibrations are recognised indirect interferences.
The residential locality matters.
The interference occurs every night.
The timing and duration support unreasonableness.
There is no need to manufacture a Rylands argument based merely on the fact that machinery is present.
Scenario B
Zara owns a house beside a workshop. The owner has brought twenty large containers of industrial oil onto the land and stored them beside the boundary. One splits and the oil flows into Zara's garden, destroying ordinary plants.
The facts strongly raise Rylands v Fletcher.
Why?
oil has been brought onto the land
it has been accumulated
it may cause mischief if it escapes
the use must be tested for being extraordinary and unusual
the oil itself escapes
it causes property damage.
The factual structure is fundamentally different from the repeated noise scenario.
A scenario may contain different harms
Do not assume every consequence in a scenario must receive the same answer.
Consider:
D stores a large quantity of toxic chemical on land beside C's house. The chemical escapes. It destroys C's garden plants and causes C to suffer headaches.
For Rylands v Fletcher:
the property damage may be actionable
the headaches are personal injury and are not recoverable under Rylands.
OCR specifically tested this distinction in 2024.
A strong legal answer therefore deals with each type of harm separately.
Selecting the tort from a mixed scenario
Consider:
Noah owns a house beside a manufacturing business. For six months, machinery at the business has produced loud noise every night. The company also keeps several large tanks of chemical cleaner in its yard. One tank splits and cleaner flows into Noah's garden, destroying his vegetable plants.
The scenario contains two legally distinct problems.
The nighttime noise
This points towards private nuisance because it involves:
indirect interference
repeated disturbance
use and enjoyment of land
locality and duration.
The escaped chemical
This points towards Rylands v Fletcher because it involves:
a substance brought onto land
accumulation
possible likelihood of mischief
possible extraordinary and unusual use
actual escape
property damage.
The lesson is important:
You do not always need to choose one tort for the entire factual story.
Different conduct within the same scenario may raise different torts.
Comparing the defences in a mixed scenario
Continue the example:
The business has operated for 30 years but the nighttime machinery began only six months ago. The chemical tank was damaged by an unknown trespasser.
For the private nuisance claim:
The defendant might consider prescription.
However, the actionable nighttime nuisance has existed for only six months. The age of the business itself does not establish the required period of actionable nuisance.
This reflects Coventry v Lawrence.
For the Rylands v Fletcher claim:
The damaged tank raises act of a stranger.
Under Perry v Kendricks Transport, the question includes whether the defendant could have anticipated or guarded against the third-party interference.
The same scenario therefore requires two different defence analyses.
Exam problem-solving method
Step 1: separate the incidents
If the facts contain more than one form of interference, deal with them separately.
For example:
nightly noise
chemical escape
Step 2: select the likely tort for each
Nightly noise:
Private nuisance.
Chemical escape:
Potentially Rylands v Fletcher.
Step 3: state the correct legal test
Do not mix legal vocabulary.
Private nuisance:
indirect and unreasonable interference with use or enjoyment of land.
Rylands:
accumulation, likelihood of mischief, extraordinary and unusual use, escape and foreseeable actionable damage.
Step 4: apply every relevant element
OCR repeatedly rewards answers that make specific links between the legal rule and the facts rather than giving bald assertions.
For example:
Weak:
"There has been an escape."
Better:
"The chemical itself has moved from land controlled by D across the boundary onto land controlled by C, satisfying the escape requirement."
Step 5: apply only relevant defences
Look for factual triggers.
Private nuisance
legislation authorising the activity → statutory authority
20 years of actionable nuisance → prescription
claimant moved there later → coming to nuisance, but not a defence
public benefit → not a defence.
Rylands
independent third party causes escape → act of stranger
exceptional natural event → act of God
claimant consent → volenti
arrangement for common benefit → common benefit
claimant causes loss → claimant's fault.
Step 6: reach separate conclusions
Avoid one vague final sentence.
Instead:
D is likely to be liable in private nuisance for the nighttime noise because...
and:
D may satisfy the requirements of Rylands v Fletcher for the escaped chemical, although the act of a stranger defence may...
This produces a much clearer legal argument.
Key Words 🔑
Key word | Student-friendly definition | How it may be used in an exam |
Private nuisance | An unlawful and indirect interference with another person's use or enjoyment of land or rights over it. | Select this tort where the facts involve unreasonable interference such as repeated noise, fumes or smells. |
Rylands v Fletcher | A land-based tort concerning a harmful thing brought onto and accumulated on land which escapes in circumstances satisfying the Rylands requirements. | Select this tort where an accumulated thing escapes onto the claimant's land. |
Unreasonable interference | Interference going beyond what the law regards as reasonable in the circumstances. | Apply locality, duration and sensitivity in private nuisance. |
Extraordinary and unusual use | The Rylands requirement that D's use of land be extraordinary and unusual considering the circumstances of the time and place. | Apply Transco v Stockport MBC, rather than private nuisance's reasonableness factors. |
Escape | Movement of the accumulated thing from land or circumstances controlled by D to land controlled by C. | Use to distinguish a Rylands claim from a general private nuisance interference. |
Hints from the Examiner Reports 💡
Examiner hint: Explain legal principles rather than merely stating them. OCR's reports on both private nuisance and Rylands v Fletcher distinguish stronger responses, which explained the law, from weaker answers that simply listed elements.
Examiner hint: Do not merge separate Rylands requirements. OCR's 2024 report identified candidates who confused naturally occurring things with extraordinary use and who dealt with foreseeability at the wrong stage.
Examiner hint: Do not use the "shotgun approach". In the 2023 private nuisance question, some candidates wrote everything they knew about nuisance, including irrelevant malice and defences. This wasted time that could have been spent applying the relevant rules.
Examiner hint: Use factual scaffolding. Successful Rylands responses identified clues supporting each individual requirement, including bringing on and accumulating, likelihood of mischief, escape and foreseeable harm.
Examiner hint: Keep the extraordinary-use test precise. OCR has specifically warned against saying that the thing accumulated is "non-natural". The issue is the defendant's use of the land.
Examiner hint: Apply defences accurately. In the 2024 private nuisance question, students lost marks by using planning permission instead of statutory authority, miscalculating prescription and treating coming to the nuisance or social utility as valid defences.
Common Mistakes ⚠️
Mistake: Choosing Rylands v Fletcher whenever a substance is dangerous
Why this is incorrect: A dangerous substance alone does not establish Rylands v Fletcher. The claimant must establish all the requirements, including bringing onto and accumulation, extraordinary and unusual use, escape and foreseeable actionable damage.
How to improve: Run through the Rylands checklist element by element.
Mistake: Choosing private nuisance simply because something is annoying
Why this is incorrect: The tort concerns interference with land or its use and enjoyment, and the relevant legal requirements must be satisfied.
How to improve: Identify the claimant's interest in land, the indirect interference and the factors showing legal unreasonableness.
Mistake: Applying locality, duration and sensitivity to Rylands v Fletcher
Why this is incorrect: These are central private nuisance reasonableness considerations. Rylands has its own requirements.
How to improve: For Rylands, concentrate on accumulation, likelihood of mischief, extraordinary and unusual use, escape and foreseeable actionable damage.
Mistake: Applying Transco's extraordinary-use test as the private nuisance test
Why this is incorrect: Private nuisance asks whether the interference is unreasonable. The Rylands action separately considers extraordinary and unusual use of land.
How to improve: Label the tort before applying the legal test.
Mistake: Assuming every private nuisance requires physical damage
Why this is incorrect: Private nuisance can involve interference with the claimant's comfort and enjoyment of land without physical damage.
How to improve: Use Halsey v Esso Petroleum to distinguish physical damage from interference with use and enjoyment.
Mistake: Assuming Rylands covers personal injury
Why this is incorrect: OCR materials expressly exclude personal injury from recovery under Rylands v Fletcher.
How to improve: Separate property harm from personal injury and apply Transco v Stockport MBC.
Mistake: Mixing the defences
Why this is incorrect: The torts have different land-specific defences.
How to improve: First identify the tort, then use its defence checklist.
Mistake: Treating common benefit and public benefit as the same argument
Why this is incorrect: Public or social benefit is not a defence to private nuisance. Common benefit is a recognised Rylands defence.
How to improve: Ask who benefits. General community benefit points towards social utility. Shared benefit between the relevant parties may raise common benefit.

Indicative answers and mark scheme
Question 1
Award 1 mark for an appropriate similarity, such as:
the claimant needs the relevant interest in the affected land.
Question 2
Award up to 4 marks for two developed differences.
Examples include:
private nuisance requires indirect interference, whereas Rylands specifically requires the accumulated thing to escape
Rylands requires bringing onto and accumulation, whereas private nuisance does not
private nuisance considers unreasonable interference, including locality, duration and sensitivity, whereas Rylands requires extraordinary and unusual use
Rylands expressly requires foreseeable actionable damage and excludes personal injury.
Question 3
Award up to 6 marks for explaining that:
private nuisance requires the interference to be legally unreasonable
factors can include locality, duration and sensitivity
Rylands instead considers whether D's use of land is extraordinary and unusual in the circumstances of the time and place
Transco v Stockport MBC is relevant to Rylands
the tests belong to different legal structures
a good application should therefore avoid replacing one test with the other.
Question 4

Credit should be based on the tort most clearly raised by the factual indicators provided.
Question 5
Award up to 8 marks for accurate comparison.
Private nuisance content may include:
statutory authority
prescription
coming to the nuisance is not a defence
social utility or public benefit is not a defence
planning permission alone does not defeat an actionable nuisance.
Rylands content may include:
act of a stranger
act of God
volenti non fit injuria
common benefit
claimant's fault.
Higher-level responses should distinguish concepts rather than merely producing two lists.
Question 6
A strong answer should separate the two incidents.
Noise and vibrations
The appropriate tort is private nuisance.
Luca owns the house and therefore has the relevant interest in land.
Noise and vibrations are recognised forms of indirect interference.
Because the problem concerns use and enjoyment rather than stated physical damage, Luca must establish unreasonable interference.
Relevant factors include:
locality, depending on the character of the area
duration, because the activity has continued every evening for eight months
timing, because it continues until midnight
the effect on ordinary sleep.
The principles are studied in [Lesson 127. Unreasonable interference].
Escaped cleaning liquid
The facts instead raise Rylands v Fletcher.
The liquid has:
been brought onto the workshop land
been accumulated in twenty containers.
Luca would need to establish:
that it was likely to cause mischief if it escaped
that the storage constituted an extraordinary and unusual use in the circumstances
that the liquid itself escaped
that the property damage was reasonably foreseeable.
The destroyed plants are capable of being actionable property harm.
Conclusion
Private nuisance is the appropriate structure for the repeated noise and vibrations, while Rylands v Fletcher is clearly raised by the accumulated liquid escaping and damaging Luca's land.
Question 7
A high-level answer should separate the noise from the fuel escape.
Noise
The relevant tort is private nuisance.
Anya owns the affected cottage and therefore has an interest in the land under Hunter v Canary Wharf.
The repeated nighttime noise is an indirect interference with her ordinary use and enjoyment of the property.
There is no stated physical damage, so Anya must establish that the interference is unreasonable.
The facts support:
significant duration, because the noise occurs every evening
nighttime interference with ordinary sleep.
Any information about locality should also be applied if available.
The defendant's 25-year argument
Rapid Recreation appears to raise prescription.
However, prescription requires an actionable nuisance for at least 20 years.
Although the business has occupied the site for 25 years, the relevant noisy activity has existed for only three years.
Under Coventry v Lawrence, the period relates to the actionable nuisance rather than merely the defendant's presence or activity on the land.
The defence is therefore unlikely to succeed.
Fuel escape
The relevant tort is Rylands v Fletcher.
Rapid Recreation keeps large quantities of specialist fuel in tanks.
The facts therefore support:
bringing onto and accumulation
possible likelihood of mischief if the fuel escapes
the need to determine whether this is an extraordinary and unusual use of the land
an actual escape from land controlled by Rapid Recreation to Anya's land
property damage to Anya's fruit trees.
The fuel itself has escaped and the fruit trees constitute property harm.
Any final conclusion on liability should also consider whether the property damage was reasonably foreseeable.
Act of a stranger
The tank was deliberately damaged by an unknown trespasser.
This raises the act of a stranger defence under Perry v Kendricks Transport.
The trespasser is apparently outside Rapid Recreation's control, which supports the defence.
However, Rapid Recreation knew about several previous incidents of trespass.
This suggests that further interference might have been anticipated and that the company could potentially have taken precautions to guard against it.
OCR's 2025 materials recognise that the success of this defence can turn on precisely this issue.
Overall conclusion
Anya has a strong potential private nuisance claim concerning the nighttime noise, and the 25-year existence of the business does not establish prescription because the actionable nuisance has existed for only three years.
The escaped fuel should be analysed separately under Rylands v Fletcher. The basic requirements may be satisfied, but Rapid Recreation's act of a stranger defence is weakened by its knowledge of previous trespass and the possibility that it could have guarded against further interference.
The strongest answer therefore selects and applies different torts and different defences to the separate incidents, rather than merging all of the land-based rules into one analysis.
