Reference Decision: cc • No. 81-13.446 • 1982-11-16 • View decision →
Imagine: you buy a building plot in Sophia-Antipolis, with an undertaking to build within four years. But the administration refuses your permit, or the local urban plan (PLU) changes in the meantime. You do not build. And then the tax authorities demand registration duties (taxes paid on purchase) plus penalties. You can challenge this, of course. But be careful: invoking force majeure (an unforeseeable, irresistible, external event) is not enough to be heard. The Court of Cassation, in a judgment of 16 November 1982, reminded that the judge must check whether the taxpayer actually took all necessary steps to build. A decision directly affecting landowners in the Alpes-Maritimes, where planning constraints are numerous.
What happened? An individual buys a building plot in Le Cannet. He undertakes to build a house within a given period. But he does not obtain the building permit and does not build. The tax authority then issues a recovery notice (AMR) to claim the unpaid registration duties. The taxpayer objects, arguing that the opposition from the Department of Public Works constitutes force majeure. The court rules in his favour. But the authority appeals to the Court of Cassation. The Court quashes the judgment: the lower court did not address the authority's argument that the taxpayer neither proved that he had applied for a building permit within the time limits nor that the administrative obstacle personally prevented him from building.
In short, this decision sets a simple rule: to avoid the penalty, it is not enough to say "the PLU changed" or "the administration refused". You must prove that you did what was necessary to build, and that the obstacle was personal and insurmountable. A lesson for any owner of a building plot within the jurisdiction of Grasse or elsewhere.
The Facts: A Story That Happens Every Day
Mr X, owner in Sophia-Antipolis, bought a building plot in 1975. In the sale deed, he undertook to build a dwelling house within four years, in accordance with the legislation on planning taxes (today, the development tax and registration duties). But the construction project met with a refusal from the Department of Public Works (predecessor of the DDTM). Mr X did not build. The tax authority served him with a recovery notice for 15,000 francs (about €2,300) in registration duties and ancillary taxes, plus penalties. Mr X objected before the Tribunal de grande instance (TGI), arguing that the administrative refusal constituted force majeure preventing him from fulfilling his obligation.
The TGI, perhaps sympathetic to the situation, upheld the objection and annulled the recovery notice. It held that the plot was building land at the time of purchase and that the administration's opposition justified force majeure. But the tax authority disagreed. It appealed to the Court of Cassation, arguing that the court had not addressed its submissions: Mr X had never applied for a building permit within the legal time limits, and had not proved that the administrative obstacle personally prevented him from building. In other words, the mere existence of a refusal is not enough: the refusal must have been issued in response to a valid application and must have been insurmountable.
The Court of Cassation quashed the judgment and remanded the case to another Court of Appeal. For the Court, the lower court had made an error of law by not verifying the evidence provided by the taxpayer. In other words, force majeure is not presumed: it must be proved.
The Reasoning of the Court — Analysed
The Court of Cassation relies on the rules of civil procedure and tax law. Essentially, it reminds that the judge must address the points raised by the parties (Article 455 of the Code of Civil Procedure). Here, the authority had argued that the taxpayer did not prove that he had applied for a building permit within the time limits, nor that the administrative obstacle personally prevented him from building. The court, by not addressing this argument, violated its duty to give reasons.
But beyond procedure, the judgment establishes a substantive rule: force majeure, to be recognised, must be characterised by three criteria: unforeseeability, irresistibility, and externality (Article 1218 of the Civil Code, since the 2016 Ordinance, but already applicable under former Article 1148). In tax matters, the taxpayer invoking force majeure to avoid a building obligation must prove that he took all necessary steps to perform his undertaking. Specifically, he must demonstrate that he submitted a complete and compliant building permit application within the prescribed time limits, and that the refusal he received was final and insurmountable. This is not the case if the taxpayer never applied, or if the refusal was foreseeable (for example, if the PLU had just been amended).
This decision is a classic application of the law of evidence in tax matters. It is not a reversal but a confirmation of the strictness required of taxpayers. undefined, I have encountered cases where owners in Le Cannet or Antibes thought that a simple change of PLU was enough to exonerate them. However, the case law is consistent: you must have acted in good time.
What few people know is that the burden of proof lies with the taxpayer. The authority does not have to prove that you could have built. It is up to you to show that you did everything possible. A lesson to remember before buying land with a building undertaking.
What This Changes for You — Practically
For a landlord owner in Sophia-Antipolis: if you buy land with an undertaking to build rental housing, and you do not build, the tax authority will demand the registration duties (about 5-6% of the price) plus late payment interest (0.20% per month) and a 10% penalty. To avoid this, it is not enough to invoke a permit refusal: you must prove that you submitted a complete application within the time limits, and that the refusal was personal (not a general PLU change).
For an individual buyer in Le Cannet: if you buy land with a 4-year building deadline, and you cannot obtain the permit, you risk a tax assessment. If you did not even apply, force majeure will be rejected. Example: Mr Z buys a plot for €200,000, registration duties €12,000. If he does not build, he will have to pay these €12,000 plus penalties, about €15,000. To avoid this, he must apply for his permit within 2 years of purchase (a common deadline in the deed).
But note: this decision does not only concern registration duties. It also applies to other contractual building obligations, for example in a sale in the future state of completion (VEFA) or a building lease. In all cases, proving force majeure is difficult. If you are in this situation, you must keep all evidence: dated permit application, receipt of filing, refusal decision, any administrative or judicial appeals. Without this, the judge will not follow you.
Four Tips to Avoid This Type of Dispute
- File your building permit promptly: as soon as you buy the land, start the process. Do not delay, even if the project is not finalised. Filing within 6 months is a good reflex.
- Keep all evidence: keep the receipt of the permit application, correspondence from the administration, refusal decisions, and proof of appeals. All this will form your force majeure file.
- Anticipate planning changes: before buying, check the current PLU and any proposed amendments. If an area is being rezoned, the risk of refusal is foreseeable and cannot be invoked as force majeure.
- Consult a lawyer lawyer: if you receive a recovery notice, do not respond alone. A lawyer will help you gather evidence and draft the objection in the correct form and within the time limit (30 days from notification).

The Court of Cassation has confirmed this position several times. For example, in a judgment of 10 July 1984 (No. 82-14.527), it held that a change of PLU is not force majeure if it was foreseeable at the time of purchase. Similarly, in a judgment of 18 December 1990 (No. 89-15.621), it specified that an error by the administration regarding the building status of the land does not constitute force majeure if the owner did not check the planning certificate.
The trend is therefore consistent: judges are demanding. Since 1982, the strictness has not relaxed. On the contrary, with the multiplication of environmental constraints (Coastal Law, Mountain Law, natural risks), owners must be extra vigilant. In Sophia-Antipolis, where natural areas are protected, a permit refusal is common. But to invoke it as force majeure, you must have submitted a proper application.
This case law is part of a broader move to secure tax revenues. The administration does not hesitate to pursue owners who have not built, even in cases of difficulty. In the future, it is likely that judges will continue to require strict proof, especially as the amounts at stake are large (registration duties can reach several tens of thousands of euros).
Summary and Next Steps
FAQ
- What should I do if I receive a recovery notice for non-building? Respond within 30 days with a reasoned objection, attaching all evidence of your steps (permit application, refusal, appeals). Consult a lawyer.
- Can I invoke force majeure if the PLU changed after my purchase? Yes, but only if the change was unforeseeable and you had already applied for a permit. If the PLU was under revision at the time of purchase, force majeure will be rejected.
- What are the time limits for applying for a building permit? The sale deed usually sets a deadline (2 to 4 years). If no deadline is set, the law requires you to build within a reasonable time. In practice, 4 years is a maximum.
- What is the cost of an objection? Lawyer's fees vary, but an initial consultation at €45 can guide you. If you need to go to court, expect €1,500 to €3,000 for a first-instance procedure.
- What happens if I lose? You will have to pay the duties plus penalties (late payment interest + 10%). In case of bad faith, heavier penalties may apply (up to 40%).
