Neighbourhood Nuisances: Judges Have Sovereign Discretion to Decide Whether Damage Exceeds Normal

Imagine: you have just bought a house in Orange, with a small swimming pool. In the summer, you invite friends, enjoy the sun. But your neighbour, Mr. D., owner of an adjoining flat, complains that your pool attracts mosquitoes. He sues you for neighbourhood nuisance (abnormal disturbances between neighbours). You wonder: how far does your right to enjoy your property go? And can the judge decide that your pool is a source of excessive inconvenience?

This question was decided by the Court of Cassation (the highest French court) in a judgment of 24 April 1970 (No. 68-11.924). The judges affirmed that the lower courts (courts of appeal, judicial courts) have sovereign power to assess whether the disturbances caused by one owner to his neighbour exceed the normal inconveniences of neighbourhood. In other words, it is for the trial judge to decide, on a case-by-case basis, what is acceptable or not.

In this article, I will tell you the story behind this decision, explain its reasoning, and above all give you practical keys on how to react if you are faced with a neighbourhood conflict. Whether you are an owner in Cavaillon, a tenant in Avignon or a property professional, this case law concerns you.

The facts: a story like any other

It all begins in Palavas-les-Flots, in the Montpellier-Plage housing estate. Mr. Roque, owner of a plot, complains that his neighbour, Mr. Suttel, has dug a pond in his garden. This pond, according to Roque, attracts mosquitoes and other creatures into his flat. He therefore sues him for neighbourhood nuisance and for violation of article 14 of the estate's specifications, which prohibits constructions or installations that may harm neighbours.

But the specifications provided that co-owners could waive the right to rely on this clause. Suttel claims that Roque has waived, notably by attending general meetings without protesting. Roque contests this: for him, mere participation in meetings does not constitute a waiver of the right to have a disturbance stopped.

The Montpellier Court of Appeal rules in favour of Suttel: it considers that the disturbances are not established. Roque appeals to the Court of Cassation. The Court of Cassation dismisses his appeal: it considers that the trial judges sovereignly assessed the facts, notably by analysing the circumstances of time and place, and that they were able to find that the nuisances were not proven.

What is interesting is that the Court of Cassation does not question the judges' assessment: it simply reminds that it is for them to decide, based on the concrete elements of each case, whether the disturbance exceeds the normal inconveniences of neighbourhood.

The reasoning of the court — dissected

The Court of Cassation bases its decision on the general principles of tortious liability (the obligation to repair damage caused by one's fault, provided for in Article 1240 of the Civil Code). But note: here, it is not a question of fault in the strict sense, but of an abnormal neighbourhood disturbance. Case law has created an autonomous theory: every owner must bear the normal inconveniences of neighbourhood, but if the disturbance exceeds this normal level, he must be compensated or have the nuisance stopped.

The sovereign power of the trial judges means that the Court of Cassation does not review the assessment of facts by the appeal judges. It only verifies that the judges have properly reasoned their decision and have not violated the law. In this case, the Court of Appeal examined the circumstances of time and place (for example, mosquito season, proximity of the pond) and concluded that Roque did not provide proof that the nuisances exceeded the normal.

This decision is neither an evolution nor a reversal: it confirms constant case law. What few people know is that this principle applies to all kinds of disturbances: noise, smell, views, trees, etc. Judges have great freedom of assessment, which makes each case unique.

What it changes for you — concretely

In practice, this decision directly impacts you, whatever your profile:

• Landlord: If your tenant complains about a noisy neighbour, you can take legal action, but you will have to prove that the noise exceeds the normal level. For example, parties every weekend until 3 a.m. may be abnormal; occasional barking, no.
• Tenant: You can claim damages from your landlord for disturbance of enjoyment if the neighbourhood is unbearable. But be careful: you must prove the disturbance. A well-documented file (photos, statements, bailiff's report) is essential.
• Buyer: Before buying a property in Cavaillon, inquire about potential nuisances (agricultural activities, workshops, etc.). A swimming pool can be a source of conflict: make sure the co-ownership rules or specifications do not prohibit it.
• Co-owner: If you install a noisy air conditioner, you could be sued. The judge will assess whether the noise is excessive compared to the normal level in the neighbourhood.

Concrete example: in Cavaillon, an owner installed a chicken coop. His neighbours complain about the smells. The judge will examine the distance, the number of chickens, the prevailing winds. If the chicken coop is 2 metres from the neighbour's terrace, the disturbance will probably be deemed abnormal. If it is 20 metres away, perhaps not.

If you are in this situation, you must first gather evidence: photos, videos, testimonies, registered letters. Then, try conciliation (for example via the free justice conciliator). If that is not enough, legal action can be taken. Timeframes vary: proceedings often last several months. The amounts of damages can range from a few hundred to several thousand euros depending on the severity.

Four tips to avoid this type of dispute

• Know the co-ownership rules or specifications: Before any installation (pool, garden shed, antenna), check the clauses. Some prohibit ponds or constructions without authorisation.
• Talk to your neighbours: A simple exchange can avoid a trial. Explain your project, listen to their concerns. Sometimes an amicable solution is possible (e.g. move the pond, install an anti-mosquito pump).
• Have the disturbances recorded by a bailiff: If the conflict persists, a bailiff's report (about £150-200) is solid evidence in court. It can describe noise, visual, or olfactory nuisances.
• Consult a lawyer before acting: A professional will assess your chances and guide you to the best strategy (mediation, interim proceedings, full trial). A consultation can save you unnecessary costs.

Further reading: related case law and developments

The Court of Cassation has reaffirmed this principle on several occasions. For example, in a judgment of 19 November 1986 (No. 84-16.679), it held that trial judges sovereignly assess whether a tree planted on the boundary causes an abnormal disturbance. Similarly, for noise nuisances, the Court of Cassation reminded that the disturbance must be assessed in concreto (judgment of 4 July 2019, No. 18-19.743).

The current trend is towards increased protection of neighbours' tranquillity, particularly in matters of noise. Courts are increasingly demanding on evidence. But the judges' freedom of assessment remains complete, which can create disparities depending on the jurisdiction.

For the future, we can expect judges to take into account new nuisances (e.g. drones, LED lights, etc.) using the same method: comparing the disturbance to the normal level of the neighbourhood.

Checklist before taking action

FAQ: 5 practical questions

1. What is an abnormal neighbourhood disturbance? It is a nuisance that exceeds the ordinary inconveniences of living in society (noise, smell, view, etc.). Example: a neighbour who drills a wall at 7 a.m. every day may constitute an abnormal disturbance.
2. Do I have to prove the disturbance? Yes, it is up to you to provide proof. Gather concrete elements (bailiff's report, photos, statements).
3. Can I act without a lawyer? Before the judicial court, a lawyer is compulsory for claims over €10,000 or complex cases. For small disputes, you can refer the matter to the free justice conciliator.
4. What time limits to act? You have 5 years from the manifestation of the disturbance to bring a liability action (five-year limitation period).
5. What cost? A bailiff's report costs about €150-200. Lawyer fees vary: expect €500-1500 for a simple procedure. Damages can reach several thousand euros.
