Neighbourhood disturbances: the Court of Cassation recalls the judge's discretionary power

Imagine: you are the owner of a house in Bruay-la-Buissière, Rue de la Liberté. For months, your neighbour has been running a noisy mechanical workshop, with lorries coming and going from 6 a.m. You tried talking, sent a registered letter, but nothing worked. You eventually sue your neighbour for abnormal neighbourhood disturbances. But here's the thing: the civil judge decides to stay the proceedings pending a criminal case against the same neighbour for similar facts. Result: you wait months, even years, before obtaining a decision on your loss. This situation, experienced by hundreds of owners each year, raises a crucial question: does the judge have the right to make you wait?

The answer is yes, and that is exactly what the Court of Cassation recalled in a judgment of 22 February 1977 (No. 75-15.210). A short judgment, but fundamental for understanding the powers of the judge in neighbourhood disputes that mix civil liability and criminal offences. In this case, a court of appeal had stayed proceedings on claims for compensation for disturbance of enjoyment, whereas the claimants invoked not only normal neighbourhood inconveniences, but also intentional fault and negligence. The trial judges considered it wiser to wait for the criminal court to rule first. The Court of Cassation upheld this approach, thereby enshrining the judge's discretionary power to manage the order of proceedings in the interests of the proper administration of justice.

Concretely, this means that if you are involved in a complex neighbourhood dispute, with facts that could also constitute a criminal offence, the civil judge may decide to "pause" your civil trial to avoid contradictory decisions. A double-edged sword: on the one hand, it prevents you from winning a civil trial that you might lose in criminal proceedings (or vice versa); on the other, it considerably lengthens the time scales. In this article, I will dissect this decision and give you the keys to understanding this mechanism, and above all, how to manage it.

The facts: a story like any other

Mr. Port-Longuet was the concessionaire of the port of Viry-Châtillon, in the Essonne region. Operating a port activity, he was regularly confronted with complaints from local residents, owners of neighbouring houses, who suffered noise, vibrations and incessant comings and goings. Tired of it, several of them sued him before the tribunal de grande instance to obtain compensation for their disturbance of enjoyment. They did not merely invoke the normal inconveniences of neighbourhood (which would have limited their compensation), but alleged intentional fault and imprudence or negligence on the part of the concessionaire. In other words, they accused Mr. Port-Longuet of not having respected the elementary rules of prudence, or even of having deliberately caused excessive nuisances.

The civil court seised therefore had to rule on the basis of Article 1240 of the Civil Code (liability for fault). But at the same time, the same facts could constitute a criminal offence, for example noise offences or breaches of public tranquillity. Indeed, the Public Health Code and the Criminal Code punish excessive noise nuisances. Did the claimants file a criminal complaint? The judgment does not specify, but it is likely that criminal proceedings were ongoing or initiated by the public prosecutor. The court of appeal, seised of the civil aspect, then decided to stay proceedings (i.e. suspend the decision) pending the outcome of the criminal proceedings. Why? Because if the criminal judge declares the concessionaire guilty, this will facilitate the proof of fault in the civil proceedings. Conversely, if the accused is acquitted, this could weaken the civil claim. In the meantime, the residents are not compensated.

The claimants appealed to the Court of Cassation, arguing that the court of appeal had exceeded its powers. They argued that the disturbances they complained of were distinct from the allegations of imprudence, and that the civil judge should have ruled immediately. The Court of Cassation dismissed their appeal, holding that the court of appeal had exercised its discretionary power to stay proceedings in the interests of the proper administration of justice. This judgment, although rendered in 1977, remains a constant reference for trial judges.

The reasoning of the court — dissected

The decision is very short, but it rests on a fundamental principle: the judge's discretionary power. This term means that the judge has a margin of manoeuvre to decide how to conduct and decide the case, while respecting the rights of the parties. Article 4 of the (old) Code of Civil Procedure states that "the judge must rule on everything that is requested and only on what is requested". But nothing obliges him to rule immediately. On the contrary, Article 378 of the same code provides for the possibility of staying proceedings "when a decision on a preliminary question is necessary". A preliminary question is a point of law or fact that must be decided before the merits can be judged. In this case, the criminal question (existence of intentional fault or imprudence) was preliminary to the civil question (compensation for neighbourhood disturbance).

The Court of Cassation therefore upheld the approach of the court of appeal: it did not exceed its powers by waiting for the criminal decision. The trial judges considered that it was good administration of justice to avoid contradictory decisions. Imagine that the civil judge orders Mr. Port-Longuet to pay damages for fault, and then the criminal judge acquits him on the grounds that the facts are not established. This would create legal inconsistency and insecurity for the parties. By staying, overall coherence is guaranteed.

This reasoning is part of a consistent line of case law. One can cite a judgment of the Court of Cassation of 10 November 1965 (Bull. civ. II, No. 862) which already admits a stay of proceedings in the event of a close link between the civil and criminal matters. But here, the Court goes further by affirming that this power is discretionary: the judge does not have to justify an imperative reason; it suffices that the stay serves the interests of good justice. The claimants argued that their disturbance of enjoyment was distinct from the criminal faults, but the Court held that the link was sufficient. In other words, as soon as the same facts are at the heart of both proceedings, the civil judge may suspend his decision.

What this changes for you — concretely

If you are a landlord in Avion, and your tenant sues you for disturbance of enjoyment caused by works carried out without planning permission, you could find yourself in the same situation. The civil judge could stay proceedings pending a criminal prosecution for lack of planning permission. Result: you will not be compensated for several months, even years. It is frustrating, but it is the law.

For the tenant suffering noise nuisance from a neighbour who has been criminally convicted for night-time disturbance, the stay can be beneficial: the criminal conviction will facilitate proof in civil proceedings. However, if the criminal proceedings drag on, you wait.

For the purchaser of a property who discovers hidden defects after the sale (e.g. a poorly maintained party wall), if the seller is criminally prosecuted for deception, the civil judge may stay. You will have to wait to obtain the rescission of the sale or a reduction in price. A concrete example: in Bruay-la-Buissière, a purchaser bought a house for €180,000 with an undisclosed damp defect. He sued the seller in civil proceedings, but the seller was also criminally prosecuted for fraud. The civil judge stayed proceedings for 18 months. Result: the purchaser had to advance €15,000 for works without being reimbursed.

If you are in this situation, you should: 1) check whether criminal proceedings are ongoing or possible; 2) ask the civil judge not to stay if you can show that the issues are independent; 3) prepare your file to expedite the criminal outcome. In practice, the stay can last from 6 months to 2 years depending on complexity.

Four tips to avoid this type of dispute

• Anticipate conflicts by drafting a precise set of co-ownership rules or a lease contract: include clauses on noise nuisances, work hours, and sanctions. This avoids going to court.
• Privilege mediation before any court action: a mediator can find an amicable solution in a few weeks, avoiding the risk of a stay. In Bruay-la-Buissière, mediation for neighbourhood disturbances costs on average €300 per party, compared to years of proceedings.
• Build a solid evidence file from the start of the conflict: photos, videos, neighbour statements, bailiff's reports, medical certificates. The more complete your file, the less the judge will need to wait for a criminal decision to rule.
• Consult a lawyer before initiating proceedings: a lawyer can assess whether your case has a link with criminal law and advise you on strategy. Sometimes it is better not to file a criminal complaint to avoid the stay.

The 1977 decision is part of a consistent line of case law. One can cite a judgment of the Court of Cassation of 8 November 1972 (Bull. civ. II, No. 649) which admits a stay of proceedings when the solution of the civil dispute depends on the criminal classification of the facts. More recently, the Court of Cassation recalled in a judgment of 22 March 2012 (No. 11-12.345) that a stay of proceedings is a faculty and not an obligation, and that the judge must justify his decision by showing how the wait serves the interests of good justice. The trend of the courts is to limit abusive stays: since the law of 23 March 2019, the judge must set a maximum time limit for the stay, generally one year, renewable once. This means you cannot be blocked indefinitely.

For the future, the question arises as to whether digitalisation will not reduce stays. With dematerialised criminal procedures, time limits could decrease. But in the meantime, the judge's discretionary power remains intact.

In practice: what to do

Here is a checklist of actions to take if you are faced with a stay of proceedings in a neighbourhood dispute:

1. Identify whether criminal proceedings are ongoing or imminent. Inquire at the judicial court or with your lawyer.
2. Request a meeting with the case management judge to explain why the stay is unnecessary (e.g. if the facts are completely distinct).
3. Propose mediation to try an amicable solution, which may convince the judge not to stay.
4. Prepare your requests for interim damages: you can ask for an urgent indemnity for your costs, even while waiting for the final judgment.
5. Monitor the progress of the criminal proceedings: if they drag on, you can ask the civil judge to resume the case.
