Assess private nuisance and land use
Identify a claimant's land interest and unreasonable interference, then test responsibility and the actual defence.
Exam scope and assessment notes
A Level · section 4.2.2. Original educational scenarios about the law of England and Wales, checked on 14 October 2026. Model answers are formative reasoning, not advice about a real dispute, Cambridge marks or predicted grades. Read the exact statute, case and exam-year source where a rule is disputed or changes. A larger annotated authority bank, full unseen papers and specialist law-teacher review remain outstanding.
Before you begin
- Read a short source carefully and separate its rule from the facts
- Explain which element a fact supports and what is still uncertain

- Distinguish prescription and statutory authority from planning permission
Protect use and enjoyment of land
Private nuisance concerns undue interference with the claimant's land. The claimant ordinarily needs a proprietary or possession interest, as Hunter illustrates; a guest's annoyance does not automatically create the same land claim. Responsibility may lie with a creator or someone adopting or continuing a nuisance in the legally relevant sense, not every nearby owner.
Locality, duration, frequency, intensity, abnormal sensitivity and malice inform unreasonableness. Physical damage and amenity interference can engage different locality considerations. Fearn shows that serious visual intrusion can qualify in an exceptional land-use setting; nuisance is not confined to noise and smells or a general privacy action for all observation.
Identify a real defence
Prescription generally requires the relevant nuisance to have been actionable for twenty years; simply operating an activity for twenty years is not the same. Statutory authority depends on the legislation and whether the interference is an authorised inevitable consequence despite proper care. Planning permission is not itself blanket authorisation to commit nuisance, and coming to an existing nuisance is not generally a complete defence.
Jalla distinguishes repeated activity or an ongoing responsible state of affairs from lasting damage after an isolated event. That distinction affects continuing causes of action; persistence of damage alone is not an automatic daily renewal. Public benefit may matter to remedy, but does not by itself make interference lawful.

Pause and explain
Does planning permission automatically authorise every private nuisance?
Worked example
A noisy activity has planning permission. Repeated severe night disturbance affects a neighbouring homeowner. Does permission alone defeat nuisance?
Show the worked solution
- The homeowner has a relevant land interest.
- Assess unreasonable night interference.
- Distinguish planning permission from statutory authority.
Answer Planning permission alone does not defeat the claim. The frequency, severity, locality and responsibility require assessment, followed by any genuine defence and an appropriate remedy; permission is not universal immunity.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Identify interference factors in the night-noise example.
Give me a hint
Use time, severity and repeated effects.
Compare my reasoning
- Identify repeated night disturbance.
- Assess severity and locality.
- Check responsibility and land interest.
Repeated severe night disturbance supports examining unreasonable interference in its locality. The claimant's land interest and the defendant's responsibility still need proof; planning permission alone does not answer them.
Look for these in your work
- Uses frequency
- Uses severity/locality
- Uses parties
Independent: An activity has operated for twenty years but became actionable against this land only five years ago. Is twenty-year operation alone enough for prescription?
Give me a hint
The actionable nuisance period matters.
Compare my reasoning
- Identify operation duration.
- Identify actionable interference duration.
- Apply the prescription requirement.
Twenty years of operating alone does not establish prescription. The relevant actionable nuisance period and other prescription requirements must be proved; the stipulated five-year interference does not supply twenty years.
Look for these in your work
- Distinguishes periods
- Uses actionability
- Rejects automatic defence
Application: Pollution from a one-off spill remains, but no repeated activity or ongoing responsible state is established. Does persistence alone prove a continuing nuisance?
Give me a hint
Lasting damage and a continuing source differ.
Compare my reasoning
- Identify isolated event.
- Check for repeated activity or ongoing source.
- Apply Jalla's distinction.
Lasting damage alone does not automatically establish a continuing nuisance with fresh causes of action. The repeated activity or ongoing state for which the defendant is responsible must be identified; a limitation analysis cannot be invented from persistence alone.
Look for these in your work
- Uses isolated facts
- Checks source
- Separates persistence
Common mistakes
- Giving every visitor a proprietary claim
- Calling planning permission a full defence
- Renewing claims merely because damage remains
