Restoration of Premises: The Judge Must Set a Time Limit on Pain of Nullity

Imagine: you are the owner of a house in Morlaix, and after renovation work without planning permission, the municipality sues you. The court orders restoration. But without a precise time limit, what happens? You can drag your heels, and the municipality remains powerless. That is exactly what the Court of Cassation wanted to avoid in its judgment of 18 November 2014. It requires judges to set a time limit for carrying out the restoration, on pain of rendering their decision unenforceable. A simple rule, but with concrete consequences for everyone.

Every year, hundreds of owners in Guipavas, Brest or elsewhere are faced with planning proceedings. The question everyone asks: “How long do I have to restore the premises?” This decision answers clearly: it is for the judge to say, not for the administration afterwards. And if the judge forgets, the municipality may carry out the works by default, but only after a time limit set by the judge. In other words, ambiguity is no longer allowed.

What few people know is that this obligation arises from Article L. 480-7 of the French Planning Code, a provision often overlooked. Yet it is essential to guarantee the rights of everyone: the owner knows exactly what he must do and within what time limit, and the municipality can act effectively in case of inaction. Let us dissect this decision together, with concrete examples from the Brest region.

The Facts: A Story Like Many Others

The case begins in La Courneuve, in the Paris region. An owner, Mr X, carries out unauthorised works on his land. The municipality prosecutes him for a breach of the Planning Code. Before the criminal court, the defendant is found guilty. The judge orders restoration of the premises, but in his judgment, he forgets to set a time limit for executing this measure. The municipality, dissatisfied, appeals.

On appeal, the Paris Court of Appeal confirms the guilt, but it too sets no time limit. The municipality then appeals to the Court of Cassation. Its argument: without a time limit, restoration is impossible to implement. The mayor cannot carry out the works by default, because Article L. 480-9 of the Planning Code requires that a time limit be previously set. In short, the decision is stripped of its substance.

The Court of Cassation agrees. It quashes the appeal judgment, recalling that “judges who order a measure of restoration of premises are required, under Article L. 480-7 of the Planning Code, to set a time limit for its execution”. Without this, the measure is unenforceable. The case is remitted to another formation of the Paris Court of Appeal to set a time limit. A development that shows the importance of formality in these procedures.

The Reasoning of the Court — Explained

The Court of Cassation's reasoning is based on two essential provisions of the Planning Code: Article L. 480-7 and Article L. 480-9. The first requires the judge, when ordering restoration, to set a time limit for its execution. The second allows the mayor (or the competent official) to carry out the works by default if the time limit is not respected. In short, these two articles work in tandem: the time limit is the necessary condition for the municipality to act by force.

In this case, the Court of Appeal had ordered restoration, but without mentioning a time limit. For the Court of Cassation, this is an error of law. It does not matter that the municipality has the possibility to later request a time limit from the enforcement judge (the judge responsible for supervising the execution of decisions). Article L. 480-7 is clear: the time limit must be set in the judgment itself. In other words, the judge cannot delegate this setting to another authority.

However, note: this obligation only concerns restoration ordered in the context of criminal proceedings for a planning offence. If restoration is ordered by a civil judge (for example, for nuisance), the rules are different. But in planning matters, the rule is now well established: no time limit, no possibility of forced execution. The Court of Cassation here confirms a constant line of authority, already affirmed in a judgment of 12 February 2008 (No. 07-80.180).

Finally, the Court specifies that the nullity of the judgment is incurred, meaning that the decision is quashed without remission on this point. The Court of Appeal will therefore have to rule again, but this time respecting the formalities. What few people know is that this solution also protects the owner: he knows exactly where he stands and can organise the works accordingly. A reasonable time limit, often a few months, allows him to comply without haste.

What This Changes for You — Concretely

If you own a property in Morlaix or Guipavas, and you have carried out works without planning permission, this decision concerns you directly. Now, if a court orders restoration, the judgment must imperatively mention a time limit. For example, “restoration within six months of service of the judgment”. If this is not the case, you can challenge the decision for a procedural defect.

For municipalities, such as that of Brest, this decision is an effective weapon. If the judge sets a time limit and the owner does nothing, the mayor can carry out the works by default. Concretely, the municipality hires a contractor, carries out the works, then seeks recovery of the costs from the owner. However, note: this default procedure is only possible after the expiry of the time limit set by the judge. Without a time limit, the municipality is stuck.

Let's take a concrete example: in Guipavas, an owner builds a 20 m² extension without planning permission. The court orders restoration and sets a time limit of 4 months. The owner does nothing. The municipality of Guipavas can then have the extension demolished by a contractor at a cost of €5,000, then claim this amount from the owner. Without the 4-month time limit, the municipality would have to start a new procedure to obtain a time limit, which delays everything.

For tenants, this decision may have an indirect impact. If the landlord is ordered to restore leased premises (for example, unlawful works in a flat), the tenant may suffer forced works. But the time limit set by the judge allows for organising re-letting or rehousing. In practice, I advise tenants to contact their town hall to find out if proceedings are ongoing.

Four Tips to Avoid This Type of Dispute

• Before any works, check planning rules: Consult the Local Planning Plan (PLU) of your municipality, whether in Brest, Morlaix or Guipavas. Some works require a prior declaration or planning permission. A simple phone call to the planning department can save you months of proceedings.
• If you are prosecuted, demand a time limit in the judgment: At the hearing, ask your lawyer to argue that the judgment sets a precise time limit for restoration. Without this, the decision may be challenged in cassation. This is a simple but effective procedural argument.
• Do not delay in executing the decision: Once the time limit is set, act quickly. If you exceed the time limit, the municipality can carry out the works by default at your expense. For example, in Morlaix, a demolition company may cost you between €2,000 and €10,000 depending on the extent of the works.
• If you challenge, appeal within the time limits: If the judgment does not set a time limit, you can appeal. But be careful: an appeal is not suspensive (it does not stop execution). You must therefore ask the enforcement judge to suspend the works pending appeal. A lawyer lawyer is essential.

This 2014 decision is part of a constant line. Already in 2008, the Court of Cassation had ruled (appeal No. 07-80.180) that the time limit must be set by the criminal judge. More recently, a judgment of 6 September 2016 (No. 15-83.057) recalled that this time limit runs from the date on which the decision becomes final (no further appeal possible). The trend is therefore towards increased formality, for the benefit of legal certainty.

In parallel, the legislature has strengthened the mayor's powers in planning enforcement. Since the ALUR law of 2014, the mayor may, under certain conditions, issue an order to stop work (an order ordering the immediate halt of the site) without waiting for the judge. But for restoration, the judge remains central. In the future, it is possible that the time limit may be set by regulation, but for now, the case law is stable.

What this means for you: if you are faced with proceedings, systematically check that the judgment mentions a time limit. undefined, I have come across cases where judgments were handed down without a time limit, and the municipality was unable to act for months. A simple reminder of the case law allowed the decision to be quashed in cassation. Do not neglect this detail.

In Practice: What to Do

1. Check the judgment: If you have received a judgment ordering restoration, read it carefully. Look for a mention of a time limit (for example, “within 6 months of service”). If nothing is indicated, the judgment is potentially void.
2. Consult a lawyer: A lawyer specialising in planning law can advise you on the next steps: appeal, request a time limit from the enforcement judge, or negotiate with the municipality. In Brest, several firms are competent.
3. Contact the town hall: If you are the municipality, and the judgment does not set a time limit, you can apply to the enforcement judge to set one. But prevention is better than cure: at the hearing, ask the court to set a time limit.
4. Prepare a schedule: If a time limit is set, plan the works. For example, for a demolition, hire a contractor as soon as the judgment is rendered, as time limits are often short (3 to 6 months). A delay can be costly.
5. Document everything: Keep evidence of your steps (letters, photos, quotes). In case of dispute, this will be useful. For example, if the municipality claims you did nothing, you can show that you ordered the works within the time limit.
