Reference decision: cc • No. 96-13.218 • 1998-03-10 • View the decision →
You signed a preliminary contract for sale with the municipality of Cannes: in exchange for a plot of land, it undertakes to provide infrastructure to a plot you will receive. You dream of building your house there. But a few years later, the local development plan (POS) is revised: your plot becomes non-buildable. The municipality tells you: "Sorry, we can no longer carry out the works, it is prohibited by the new POS." What to do? Go before the judicial court to seek specific performance or damages? Not so fast.
This question was decided by the Court of Cassation in a judgment of 10 March 1998 (No. 96-13.218). It recalls that when the non-performance of a contractual obligation is caused by an administrative decision (the classification as a non-buildable zone), the dispute concerns the assessment of the consequences of that decision. In other words, the competent court is not the judicial court, but the administrative court.
For a property owner or developer, this distinction is crucial. Bringing an action before the wrong court risks dismissal for lack of jurisdiction, and therefore wasting time and money. Let's break down this decision together.
The facts: a story that happens every day
Mr and Mrs X, owners in Valbonne, entered into a land exchange with the municipality of Cannes. By notarised deed, the municipality undertook to carry out on the plot obtained by the X couple infrastructure works (roads, water, electricity) and utilities, to allow the construction of residential houses. The POS approved in January 1983 classified the plot as a buildable zone. Everything was fine.
But during the revision of the POS, the plot was reclassified as a non-buildable zone. The municipality was therefore unable to perform its obligations: the works became illegal. Mr and Mrs X then sued the municipality before the tribunal de grande instance (TGI, judicial court) to obtain an order for the municipality to carry out the works or, failing that, to compensate the loss suffered.
The Court of Appeal declared the judicial court incompetent. Why? Because, in its view, the claim of Mr and Mrs X was in fact seeking compensation for the loss caused by the classification of the plot as a non-buildable zone, i.e. by an administrative decision. However, such disputes fall within the jurisdiction of the administrative court. Mr and Mrs X appealed to the Court of Cassation.
The reasoning of the court — explained
The Court of Cassation dismissed the appeal. It held that the Court of Appeal had legally justified its decision. In essence, the reasoning is as follows:
Mr and Mrs X sought an order against the municipality for non-performance of its contractual obligations. But this non-performance was directly caused by the administrative decision to classify the plot as a non-buildable zone. Indeed, the municipality could no longer carry out the works without violating the POS. The loss alleged by Mr and Mrs X was therefore not only that arising from the non-performance of the contract, but also that resulting from the change in regulations.
Now, the assessment of the harmful consequences of an administrative decision (here, the classification as a non-buildable zone) falls within the jurisdiction of the administrative court. The judicial court is not competent to hear a dispute that involves examining the legality or consequences of an administrative act. This is a fundamental principle of the separation of powers (law of 16-24 August 1790).
The Court of Cassation thus confirms established case law: when the performance of a contractual obligation is prevented by an administrative decision, the judicial court cannot order specific performance or award damages without ruling on the legality of that decision. It must declare itself incompetent.
However, note: if the loss were independent of the administrative decision (for example, if the municipality had refused to carry out the works for other reasons), the judicial court could be competent. What few people know is that the line is sometimes thin.
What this means for you — practically
This decision has important practical implications for several profiles:
Landlord or buyer: You have signed a promise with a municipality that undertakes to provide infrastructure to a plot. If, subsequently, the plot becomes non-buildable, you cannot obtain specific performance before the judicial court. You must turn to the administrative court to challenge the classification or claim damages. Concrete example: in Cannes, a serviced plot is worth about €300/m². If you lose buildability, the loss can exceed €100,000 for a 500 m² plot. You must act quickly: the challenge to the POS is subject to a two-month time limit from publication.
Property developer: You are considering a project on municipal land with promises of works. Before signing, check the POS and ensure it is not under revision. If the municipality contracts but the classification changes, you will face the same difficulty. undefined, I have encountered cases where developers had to abandon their projects for failure to anticipate this risk.
Tenant: This concerns you less directly, but if your landlord is a municipality and promised works cannot be carried out due to a classification, the same reasoning applies.
In summary: if your dispute with a municipality concerns non-performance of a contractual obligation caused by an administrative decision, go to the administrative court. The judicial court will systematically refer you to it.
Four tips to avoid this type of dispute
- 1. Check the POS before any commitment: Consult the local urban plan (PLU, formerly POS) of the municipality. Ensure the plot is buildable and that no revision is underway. You can request a planning certificate from the town hall, which informs you of the applicable rules.
- 2. Insert a revision clause in the contract: If the municipality undertakes to carry out works, provide a clause that organises the consequences of a change in classification (for example, compensation or rescission of the contract). This will allow you to avoid litigation on jurisdiction.
- 3. Keep all documents: Keep the notarised deed, promises, correspondence, successive POS documents. In the event of a dispute, these documents will be crucial to demonstrate the municipality's commitment and the date of the classification change.
- 4. Consult a lawyer lawyer before acting: Do not rush to court. A lawyer will tell you whether you should seize the judicial court (for the contract) or the administrative court (to challenge the decision). A wrong choice can cost you several months of proceedings.

Further reading: related case law and developments
This decision is part of established case law: the principle of separation of judicial and administrative authorities prevents the judicial court from dealing with administrative acts. See for example the decision TC 23 November 1959, "Société des grands cafés" or more recently, CE 30 March 2016, No. 388060, which recalls that the judicial court cannot rule on the legality of a PLU.
However, there is an exception: if the administrative decision is manifestly illegal and seriously infringes a fundamental freedom, the judicial court may intervene in interim proceedings (Article L. 521-2 of the Code of Administrative Justice). But that is not the case here.
The trend is towards strengthening administrative jurisdiction for everything related to town planning and decisions of local authorities. In practice, judicial courts are increasingly strict and declare themselves incompetent as soon as an administrative question is raised.
Key points to remember
Q: Can I sue the municipality before the judicial court for non-performance of its contractual obligations?
A: No, if the non-performance is due to a change in classification of the land (administrative decision). You must seize the administrative court.
Q: What are the time limits for challenging a classification as a non-buildable zone?
A: The challenge must be brought within two months of the publication of the new POS/PLU. After this period, you risk being time-barred.
Q: Can I obtain damages from the municipality?
A: Yes, but before the administrative court, by showing that the change in classification causes you an abnormal and special loss (for example, a loss in value of the land).
Q: What if I have already brought an action before the wrong court?
A: You can request a referral to the competent court, but this delays the proceedings. It is better to inquire beforehand.
Q: Can a notary help me when signing the deed?
A: Yes, he can draw your attention to the risks, but he is not a judge. For personalised advice, a lawyer is more appropriate.
