Town Planning: Demolition Claim Reserved for Parties to Criminal Proceedings

Imagine: you live in Istres, peacefully, when your neighbour undertakes building works without planning permission. You alert the town hall, the public prosecutor is notified, your neighbour is criminally convicted. But you, who were not a civil party to the proceedings, can you ask the criminal judge to order demolition? This question, which any property owner may one day ask, has found a clear answer in a decision of the Court of Cassation of 3 February 1976. The High Court ruled that only persons who were parties to criminal proceedings may be allowed to exercise a demolition claim under Article L.480-5 of the Town Planning Code. In other words, if you did not participate in the criminal proceedings, you will not be able to benefit from this measure. But what exactly does that change? Let us decipher this landmark decision together.

The Facts: A Story Like Many Others

Mr X, a property owner in Istres, undertook construction works on his land without obtaining the required planning permission. The public prosecutor's office initiated criminal proceedings for infringement of town planning rules (Articles L.160-1 and L.480-4 of the Town Planning Code). During the hearing before the Court of Appeal on 14 March 1975, several persons made submissions under Article L.480-5 of the same Code, which allows the criminal judge to order, inter alia, the demolition of illegal structures. Among these persons, some were not parties to the proceedings (neither defendant nor civil party). The defendant then lodged an appeal in cassation, arguing that only persons who were parties to the proceedings could benefit from this provision.

Plot twist: the Court of Cassation upheld his argument. It quashed the judgment of the Court of Appeal which had admitted these submissions, on the ground that "only persons who were parties to the proceedings may be allowed to exercise a claim" for demolition.

The Reasoning of the Court — Explained

The Court of Cassation relied on a strict interpretation of Article L.480-5 of the Town Planning Code. This provision states that, in the event of a conviction for an offence under Articles L.160-1 and L.480-4, the court may order the demolition of structures or the restoration of the premises. But the Court specifies that this power is only available to persons who were parties to the criminal proceedings. In other words, a third party not a party (for example, a neighbour who did not file a complaint or did not become a civil party) cannot ask the criminal judge to order demolition.

This reasoning follows a procedural logic: the criminal proceedings oppose the public prosecutor to the defendant. Civil parties are admitted to obtain compensation for their loss. But a mere observer, even with a legitimate interest, cannot be granted a direct right of action to obtain demolition. The Court of Cassation thus confirms a restrictive reading of Article L.480-5, which has not been amended on this point since.

In short, if you want a criminal judge to order the demolition of an illegal construction, you must be a party to the criminal proceedings, either by becoming a civil party or by intervening voluntarily. Otherwise, your only recourse will be civil or administrative proceedings.

What This Means for You — Practically

For the landlord: if your tenant builds without authorisation, you cannot request demolition in criminal proceedings if you are not a party to the proceedings. You will have to act in civil proceedings for termination of the lease or damages.

For the tenant: if your upstairs neighbour builds an illegal terrace that floods you, you must become a civil party in the criminal proceedings to hope for demolition. Otherwise, a civil action, with longer delays.

For the buyer: in La Ciotat, you buy a house with an unauthorised extension. If the seller is criminally prosecuted, you must intervene in the proceedings to request demolition. Otherwise, you inherit an irregular property without being able to rely on the criminal judge.

For the co-owner: if the co-ownership association builds without planning permission, each co-owner can individually become a civil party to request demolition. But beware: the Court of Cassation's decision also applies to legal persons.

undefined, I have encountered cases where neighbours, exasperated by an illegal construction, thought they could intervene at the hearing without formalities. However, without becoming a civil party, their request was inadmissible. This is a common mistake.

Four Tips to Avoid This Type of Dispute

• Check town planning authorisations before any property purchase. Consult the planning certificate and the planning permission at the town hall. If in doubt, call a surveyor.
• If you witness an offence, become a civil party quickly. The limitation period for the public action is 6 years for town planning offences (Article 8 of the Code of Criminal Procedure). Do not delay.
• For co-owners, have a prior authorisation voted at the general meeting. Any construction modifying common parts must be approved. Failing this, the syndic may bring a demolition action.
• In case of dispute, consult a lawyer specialised in property law. The procedural rules are complex. A formal error may deprive you of any recourse.

Further Reading: Related Case Law and Developments

This 1976 decision is part of consistent case law. For example, in a judgment of 14 November 1979 (No. 78-92.437), the Court of Cassation recalled that the benefit of Article L.480-5 is reserved for parties to criminal proceedings. More recently, the Criminal Chamber confirmed this position in a judgment of 18 January 2012 (No. 11-83.051), ruling inadmissible a demolition request made by an association not party to the proceedings.

The trend is therefore clear: judges are strict on standing. This means that in the future, if you want to use the criminal route to have an illegal construction demolished, you must imperatively be a party to the proceedings. The only possible evolution would be a legislative reform broadening Article L.480-5, but nothing is on the agenda.

In Practice: What to Do

FAQ:

• Can I request demolition without being a party to criminal proceedings? No, according to this decision, you must be a party to the proceedings (defendant, civil party, or intervener).
• What if I discover an illegal construction at my neighbour's? File a complaint with the mayor or the public prosecutor. If criminal proceedings are initiated, become a civil party to be able to request demolition.
• What are the time limits to act? The public action is time-barred after 6 years. The civil action (before the judicial court) is time-barred after 5 years from the discovery of the damage.
• Can I request demolition in civil proceedings? Yes, if you suffer an abnormal neighbourhood disturbance or if the construction violates property rights. But the procedure is longer and less effective than the criminal route.
• What does the owner risk who builds without planning permission? A criminal fine (up to €120,000) and an obligation to demolish or regularise. In case of repeat offence, possible imprisonment.
