Construction Without a Permit: When the Judge Refuses Demolition, the Court of Cassation Censures It

Imagine: you own a villa with an unobstructed sea view in Antibes. One morning, your neighbour begins work without permission. He builds a structure that blocks your view and devalues your property. You file a complaint. The criminal court convicts him but refuses to order demolition, on the grounds that 'the landscape is already scarred' by other illegal constructions. Unfair, isn't it? This is exactly the scenario decided by the Court of Cassation in 1997.

This decision, little known to the general public, is nevertheless fundamental. It answers a question every property owner asks: what to do if a neighbour builds without a permit? Can demolition be obtained? And what if the judge hides behind the bad example of others? The answer is clear: no, the judge cannot refuse full compensation for the damage by invoking a general context of laxity.

But what does this actually change for you, whether you are in Antibes, Le Cannet or elsewhere in France? Let's delve into the details of this case and its practical consequences.

The Facts: A Story Like Those That Happen Every Day

We are in Corsica, in Patrimonio, a commune with a preserved landscape but subject to a national directive on coastal planning. Mr. Jean-Patrick Y. and Mr. Jean-Pierre Z. decide to build there without a building permit. Illegal constructions that add to others, in a context of 'favouritism and repeated laxity of the authorities', as the Court of Appeal would later note.

Neighbours, who joined the proceedings as civil parties (i.e., they became parties to the criminal trial to obtain compensation for their loss), demanded the demolition of the structure and damages. The criminal court followed them, but the Bastia Court of Appeal, in a judgment of 22 February 1996, refused demolition and limited damages to a 'quasi-symbolic' amount. Why? Because, according to it, the construction could not harm the environment since the landscape was already 'scarred' by other earlier illegal constructions. And given the laxity of the authorities, the victims' loss was necessarily limited.

The civil parties appealed to the Court of Cassation. The Criminal Chamber of the Court of Cassation set aside the appeal judgment on 15 January 1997. It held that the Court of Appeal could not refuse demolition on these grounds. In other words, the fact that others had violated the law does not justify perpetuating the illegality, nor minimising the victims' loss.

The Court's Reasoning — Analysed

The Court of Cassation relies on the fundamental principle of full compensation for loss, derived from Article 1240 of the Civil Code (formerly Article 1382). This article provides that 'any act of man, which causes damage to another, obliges the person by whose fault it occurred to repair it'. In matters of construction without a permit, the fault is constituted by the absence of authorisation. The damage may be material (loss of property value, loss of view) or moral (disturbance of enjoyment).

In this case, the Court of Appeal had made two errors. First error: to refuse demolition, it invoked the 'scarring' of the landscape. But the Court of Cassation reminds that the existence of other illegal constructions cannot exonerate the responsible party from his obligation to demolish. In short, just because everyone does it does not make it legal, and the victim is entitled to the removal of the disturbance, not a reduced financial compensation.

Second error: the Court of Appeal limited damages because of the 'context of favouritism and repeated laxity of the authorities'. The Court of Cassation deemed this reason inadmissible. The loss suffered by the civil party must be assessed objectively, without taking into account the attitude of the authorities. In other words, the judge cannot say: 'since the administration turned a blind eye, your loss is lesser'. This is an infringement of the right to compensation.

This decision confirms a consistent line of case law: demolition is the natural remedy for an illegal construction. It is not automatic – the judge may refuse if it would cause a disproportionate loss to the builder – but the reasons must be serious and objective. 'Scarring' or 'laxity' are not valid reasons.

However, note: the Court of Cassation does not say that demolition must be ordered in all cases. It simply says that the reasons given by the Court of Appeal were insufficient. The case was referred back to another Court of Appeal for a fresh decision, with legally valid reasons.

What This Changes for You — Practically

If you are an owner victim of an illegal construction: you have the right to demand demolition, and this right cannot be set aside on the pretext that other illegal constructions already exist. For example, if your neighbour in Le Cannet builds a veranda without a permit that encroaches on your view, you can demand its demolition, even if the whole neighbourhood is in breach. The judge must examine your specific loss, not the general context.

If you are an owner who has built without a permit: you cannot hide behind 'everyone does it'. If a neighbour sues you, demolition is a real risk, and your arguments about the laxity of the authorities will not protect you. It is better to regularise the situation retrospectively if possible, or negotiate an amicable settlement.

If you are a buyer: before buying a property, check that all constructions are authorised. A construction without a permit can lead to a demolition action by the neighbour, even if the administration has said nothing. undefined, I have come across cases where the buyer ended up with proceedings on his hands, and a reduction of 20 to 30% in the property's value.

Amounts and timeframes: a demolition action can take 1 to 3 years of proceedings. Damages can reach several tens of thousands of euros, depending on the loss of property value. For example, if your villa in Antibes loses €50,000 due to an illegal construction, you can claim that amount.

If you are a tenant: you can also act if the illegal construction causes you a disturbance of enjoyment (loss of view, sunlight). But your action will often be brought by the owner.

Four Tips to Avoid This Type of Dispute

• Before building, check the permit: even for a small extension, a building permit or prior declaration is often necessary. Inquire at your town hall's planning department. In Antibes, for example, any modification of the facade may require authorisation.
• If your neighbour builds without a permit, act quickly: the limitation period for criminal proceedings is 6 years from completion of the works. But the longer you wait, the harder it will be to obtain demolition (the judge may consider that you have tolerated the situation). Obtain a bailiff's report and file a complaint.
• Negotiate before trial: mediation or a settlement can avoid costs. Propose that the neighbour regularise or demolish amicably. If an agreement is reached, have it approved by a lawyer.
• Keep all evidence: photos, letters, bailiff's reports, witness statements. Proof of the priority of your view or your enjoyment is crucial.

In Depth: Related Case Law and Developments

This 1997 decision is part of a consistent line of the Court of Cassation. For example, in a judgment of 3 November 2016 (No. 15-20.400), the Court reminded that demolition of a construction without a permit is the legal remedy for the loss, unless there is a manifest disproportion. Similarly, in a judgment of 12 July 2018 (No. 17-17.868), it censured a Court of Appeal that had refused demolition on the grounds that the construction was old. The trend is therefore clear: the judge cannot evade his obligation to fully compensate the loss.

What few people know is that this case law also applies in matters of subdivisions or condominiums. If a co-owner builds without authorisation (for example, a roof terrace), the condominium association can demand demolition.

Looking ahead, we can expect the Court of Cassation to maintain this line, even if lower courts (tribunals, courts of appeal) sometimes try to circumvent the rule by invoking proportionality. But the principle remains: the context of laxity does not justify depriving the victim of his right.

Key Points to Remember

FAQ:

1. Can I obtain the demolition of an illegal construction on my neighbour's property?
Yes, if you suffer direct loss (loss of view, value, disturbance of enjoyment). The judge may order it, unless it is disproportionate.

2. Can the judge refuse demolition because other illegal constructions exist?
No, the Court of Cassation prohibits it. Each case is judged individually.

3. What are the time limits for acting?
The criminal action is time-barred after 6 years. The civil action (damages) is 5 years from the discovery of the damage.

4. What if the administration has not reacted?
You can act directly in court. The laxity of the administration does not erase your right.

5. How much does a procedure cost?
Expect between €2,000 and €10,000 in lawyer's fees, plus any expert fees. But damages can cover these costs.
