Fraudulent planning permission: the criminal court may order demolition without waiting for administrative annulment

Imagine the scene: you live in Plan-de-Cuques, in a pretty village house with an unobstructed view of the Massif de l'Étoile. One morning, your neighbour starts work: a 50 m² extension, with terrace and swimming pool. You check the planning permission displayed: everything seems in order. Yet you discover that the plans submitted to the town hall do not match reality: the surface area is larger, the encroachment on the non-building zone is flagrant. In short, the permission was obtained by fraud. What do you do? File a complaint? What if the mayor does not react? How far can the criminal judge go?

The question that nags every injured owner is simple: Can the criminal judge order the demolition of a building erected on the basis of a fraudulent permission, without waiting for the administrative judge to annul that permission? In other words, is a planning permission obtained by deception a 'valid' permission until it is annulled?

The Court of Cassation, in a judgment of 9 September 2003 (No. 02-84.334), answered in the affirmative, holding that the criminal court (tribunal correctionnel, court of appeal) has jurisdiction to find a planning permission obtained by fraud non-existent, without applying the restrictions of Article L. 480-13 of the Urban Planning Code. A decision that changes the game for victims of illegal constructions. Analysis.

The facts: a story like so many everyday cases

The case pitted neighbouring owners against each other in La Ciotat. Mr and Mme A. bought a plot and obtained planning permission for a villa. Their neighbours, Mr and Mme B., noticed that the construction did not comply with the provisions of the local development plan (POS): the height exceeded the maximum allowed, the siting was too close to the boundary. Above all, they discovered that the permission had been obtained by fraudulent means: the plans filed at the town hall were deliberately inaccurate, understating the floor area and height.

The neighbours filed a complaint for an offence under the Urban Planning Code (construction without permission or non-compliant). The Marseille Criminal Court (tribunal correctionnel) fined the owners and ordered the demolition of the construction. The owners appealed: they argued that the criminal judge could not order demolition until the planning permission had been annulled by the administrative judge. According to them, Article L. 480-13 of the Urban Planning Code required staying proceedings pending the decision of the administrative court.

The Aix-en-Provence Court of Appeal agreed: it set aside the demolition order, holding that the planning permission precluded a criminal conviction for a planning offence. The neighbours appealed to the Court of Cassation. The Court of Cassation quashed the appeal judgment and restored the demolition order. It held that when the permission is tainted by fraud, it is non-existent, and the criminal judge may so find without waiting for administrative annulment.

The reasoning of the court — dissected

The heart of the debate concerns Article L. 480-13 of the Urban Planning Code. This provision states that, when a building is erected in accordance with planning permission, the criminal judge may only order its demolition after the permission has been annulled by the administrative judge. In short, the permission acts as a shield: as long as it is not annulled, the criminal judge cannot order demolition. But the Court of Cassation introduces a major exception: fraud corrupts everything. If the permission was obtained by fraud, it is deemed non-existent ab initio (from the outset). Consequently, the shield of the permission falls, and the criminal judge can directly find the offence and order demolition.

The reasoning is based on a general principle of law: fraus omnia corrumpit (fraud corrupts everything). An act obtained by fraud is void with absolute nullity, and this nullity may be found by any judge. The Court clarifies that Article L. 480-13 does not apply 'in that case', i.e., when there is fraud. In other words, the legislature did not intend to protect fraudulent constructions.

In doing so, the Court of Cassation confirms earlier case law (Crim., 12 March 1997, No. 96-82.292) and extends it. It rejects the owners' argument that only the administrative judge can assess the validity of the permission. It recalls that the criminal judge has jurisdiction to assess the existence of an offence, and that fraud deprives the permission of its character as a 'valid permission'. Note, however: this decision only concerns permissions obtained by fraud, not mere defects of legality (e.g., error by the town hall). In the latter case, administrative annulment remains necessary.

In practice, fraud must be proved: false declarations, concealment of floor area, forged plans, etc. A simple material error is not sufficient. The burden of proof lies on the party alleging fraud (the neighbour, the public prosecutor). But once demonstrated, the criminal judge can act without waiting.

What this changes for you — concretely

For an owner neighbouring an illegal construction, this decision is a powerful weapon. If you notice a construction that appears fraudulent (non-compliance with plans, height exceedance, encroachment on a non-building zone), you can:

• File a criminal complaint for construction without permission or non-compliant, denouncing the fraud. The prosecutor may open an investigation.
• Apply for demolition before the criminal court, even if the permission has not been annulled.
• Act quickly: the public prosecution is time-barred by 6 years from the completion of the works (Article 8 of the Code of Criminal Procedure).

Take a concrete example in La Ciotat. A developer builds an 8-storey building instead of the 5 allowed, by submitting forged plans. The neighbours, who lose view and sunlight, can refer the matter to the criminal court. If the fraud is established, the judge can order the demolition of the additional floors, without waiting for annulment of the permission by the administrative court. Time saved: 1 to 2 years, compared to 3 to 5 years for an administrative procedure.

For the owner-builder, the risk is considerable. In case of fraud, they face:

• A criminal fine (up to €300,000 for an individual, €1.5 million for a legal entity).
• Demolition of the building at their own expense.
• Damages to the neighbours (loss of view, loss of enjoyment, reduction in property value).

What few people know: even if the permission is not fraudulent, an administrative appeal can be lodged within 2 months of the display of the permission. But if you have let that deadline pass, the criminal route for fraud remains open if you discover misleading elements.

undefined, I have come across cases where owners had bought a house without knowing that the original planning permission was fraudulent. Result: the purchaser ends up with a building threatened with demolition. The 2003 case law is crucial for them: it allows the neighbour to act directly, but also exposes the good faith purchaser to risks. Hence the importance of checking the history of the permission before buying.

Four tips to avoid this type of dispute

• Systematically check your neighbours' planning permissions before any property purchase. Consult the register of permissions at the town hall, compare the displayed plans with the actual construction. If you are buying, require a certificate from the seller as to the conformity of the works with the permission.
• If in doubt, consult a chartered surveyor or a lawyer lawyer. A quick glance is not enough: gaps of a few centimetres can hide fraud. The cost of an expert report (€1,500 to €3,000) is negligible compared to the risk of demolition.
• Do not wait to act. As soon as you suspect fraud, take photographs, collect documents, and send a registered letter to the town hall and the prosecutor. Time is against you: the limitation period for public prosecution is 6 years, and evidence of fraud can disappear.
• If you are a builder, be scrupulous in your declarations. A 'small' error in floor area or height can be considered fraud if intentional. Better to file an amending permission than to risk demolition.

This 2003 decision is part of a consistent line of authority from the Criminal Chamber. Already in 1997 (Crim., 12 March 1997, No. 96-82.292), the Court had held that the criminal judge could find a fraudulent permission non-existent. The 2003 judgment confirms and clarifies that Article L. 480-13 does not prevent this. More recently, the Court of Cassation has extended this principle to other areas: for example, in relation to demolition permits (Crim., 10 February 2009, No. 08-83.040).

The trend is therefore towards strengthening the powers of the criminal judge in the face of planning fraud. Criminal courts no longer hesitate to order demolitions, even in the presence of a non-annulled permission, provided fraud is established. Local authorities, often reluctant to act against builders, can now rely on action by neighbours and the public prosecutor.

For the future, one can anticipate a multiplication of criminal proceedings, particularly in pressured areas (coastal areas, protected zones) where fraud is frequent. Purchasers will need to be extra vigilant: the mere existence of a permission no longer guarantees legal security if fraud is demonstrated.

Key points to remember

• A permission obtained by fraud is non-existent. The criminal judge can find this and order demolition without waiting for administrative annulment.
• Fraud must be proved. False declarations, concealment, forged plans. A simple error is not enough.
• Time limit to act: 6 years from completion of works for public prosecution. For civil action (damages), 5 years from discovery of the damage.
• What to do if you are a victim? 1. Gather evidence (photos, plans, witness statements). 2. File a criminal complaint (gendarmerie, prosecutor). 3. Consult a lawyer to bring an action before the criminal court.
• What to do if you are a builder? 1. Check the accuracy of your declarations. 2. If there is an error, apply for an amending permission before any dispute arises. 3. Never falsify documents.
