Refusal of Planning Permission: When the Courts Can Examine the Administration's Reasons Without

Imagine: you own a building plot in Creusot. You sign a promise of sale with a developer, who undertakes to obtain planning permission. But permission is refused. The developer withdraws, and you lose the sale. Whose fault is it? The developer who failed to take the right steps? The administration that refused? And crucially, can a judge examine the reasons for the refusal without encroaching on the administration's prerogatives? This is precisely the question raised in this case, decided by the Court of Cassation in 1976.

This little-known decision is nonetheless crucial for any landowner or property professional faced with a refusal of planning permission. It answers a daunting question: can a civil judge, without violating the principle of separation of administrative and judicial authorities, analyse the causes of a refusal of permission to decide a dispute between private parties? The answer is yes, provided the judge does not criticise the administrative decision itself.

In this article, we will dissect this decision, its facts, its reasoning, and above all what it changes for you in practice. Whether you are a seller, buyer, developer, or mere neighbour, you will know exactly what your rights are and how to enforce them.

The Facts: A Story That Happens Every Day

The case begins in Digoin, Saône-et-Loire. Mr Valerino, a property developer, signs a promise of sale with the X heirs, owners of a plot. The promise is conditional: Valerino undertakes to obtain planning permission within a certain period. If permission is refused, the sale is cancelled and the deposit remains with the seller. But if the refusal is attributable to the developer, he may be liable to pay damages.

Valerino applies for planning permission. The administration refuses. The developer then invokes the resolutive condition: no permission, no sale. The sellers, however, consider that Valerino is responsible for the refusal: he may have prepared his file poorly or failed to comply with planning rules. They sue him for damages.

The Dijon Court of Appeal rules in favour of the sellers. It examines the reasons for the refusal of planning permission and concludes that Valerino was at fault by submitting a non-compliant project, which led to the rejection. Valerino appeals to the Court of Cassation: he argues that the Court of Appeal violated the principle of separation of powers by criticising the administrative refusal decision.

The Court of Cassation dismisses the appeal. It holds that the Court of Appeal did not criticise the administrative decision: it merely determined the cause of the refusal (the developer's fault) to decide the contractual dispute between the parties. The principle of separation of administrative and judicial authorities is not violated.

The Reasoning of the Court — Explained

The Court of Cassation relies on the Law of 16-24 August 1790, which establishes the principle of separation of administrative and judicial authorities. In essence, a civil judge cannot annul or modify an administrative decision: only the administrative judge (tribunal administratif, cour administrative d'appel, Conseil d'État) has that power. However, this principle does not prohibit the civil judge from using the reasons for an administrative decision to assess a party's liability in a private law dispute.

In this case, the Court of Appeal analysed the refusal of planning permission to determine whether the developer had been at fault (Article 1240 of the Civil Code, which requires compensation for damage caused by one's fault). It did not say that the refusal was unjustified or unlawful: it merely noted that the project submitted by Valerino contravened planning rules, and that it was for this reason that the administration had refused. Therefore, the developer was responsible for the failure of the suspensive condition.

This judgment confirms previous case law. It does not innovate, but it clarifies a delicate line: the civil judge may 'touch' the administrative act without 'judging' it. He may use it as evidence or a legal fact, provided he does not assess its legality. Valerino's arguments — that the Court of Appeal had criticised the administrative decision — were rejected because the lower courts merely 'determined the cause' of the refusal.

What This Changes for You — In Practice

This decision is a double-edged sword, depending on which side you are on.

If you are a seller of land (like the X heirs in Digoin), you can claim against the developer who failed to obtain permission, if the refusal is due to his fault (incomplete file, non-compliant project, etc.). You do not have to bear the loss of the sale: you can claim damages equivalent to the loss of chance to sell. For example, if the land was worth €150,000 and you had to sell it 20% cheaper to another buyer, you could claim €30,000.

If you are a developer or buyer, be careful: a refusal of permission is not automatically a get-out-of-jail-free card. If the refusal is due to your negligence, you could be ordered to pay damages. Before signing a conditional promise of sale, have the feasibility of the project checked by an architect or a specialist lawyer. A refusal due to a procedural defect (missing documents) or non-compliance with the Local Development Plan (PLU) will be attributed to you.

If you are a neighbouring landowner, this case law does not directly concern you, but it illustrates that the reasons for a refusal of planning permission can be examined by a civil judge in the context of a neighbour dispute (abnormal disturbance, easement, etc.). For example, if permission is refused because the project encroaches on your land, the civil judge can use that refusal as evidence of the encroachment.

In practice, the limitation periods are those of ordinary law: 5 years from the manifestation of the damage for a civil liability action. The amounts at stake can be significant: architect's fees, loss of profit, loss of land value. Do not wait to consult a lawyer.

Four Tips to Avoid This Type of Dispute

• Carry out a feasibility study before any promise of sale: Before signing, check with the town planning department that the project complies with the PLU. An operational planning certificate will inform you of the rules applicable to the land. This avoids nasty surprises.
• Draft the suspensive condition carefully: In the promise of sale, specify who bears the risk of a refusal of permission. If the refusal is attributable to the buyer, the seller should be able to obtain damages. If the refusal is beyond the parties' control (e.g., change of regulations), the condition simply fails.
• Keep all correspondence with the administration: Keep acknowledgements of receipt of your application, letters requesting additional documents, and of course the refusal decision. These documents are essential to prove that you took the necessary steps.
• If permission is refused, do not rush: You can challenge the refusal before the administrative court within two months. At the same time, if you believe the refusal is due to a fault of your contracting party, consult a lawyer to bring a liability action before the civil court. Both avenues are possible and sometimes complementary.

The 1976 decision is part of a consistent line of the Court of Cassation. One can cite a judgment of 27 May 1975 (No. 73-14.123) which had already held that the civil judge could interpret an individual administrative act without violating the separation of powers. More recently, the Court of Cassation reiterated this principle in a judgment of 13 September 2017 (No. 16-19.503) concerning planning permission: the civil judge may assess the consequences of a refusal on a contract, without ruling on the legality of the refusal.

However, there is a divergence with the case law of the Conseil d'État, which is stricter on the principle of separation. In practice, civil judges are cautious: they limit themselves to noting the factual reasons for the refusal (e.g., 'the project exceeds the permitted height') without saying whether the administration correctly applied the rule. The trend is towards relaxation, but vigilance is required.

For the future, this case law is more relevant than ever with the increase in disputes related to planning permission, particularly in high-pressure areas like Creusot or Digoin where land is scarce. Judges are increasingly called upon to analyse the reasons for a refusal to decide disputes between private parties.

Key Points to Remember

• The civil judge may examine the reasons for a refusal of planning permission to determine contractual liability, without violating the separation of powers.
• If you are a seller and the refusal is due to the buyer's fault, you can claim damages.
• If you are a buyer, ensure that the refusal is not attributable to you to avoid being ordered to pay damages.
• Keep all documents and carry out a feasibility study before signing.
• In the event of a dispute, consult a lawyer specialising in property law promptly, as time limits are short (2 months to challenge the refusal, 5 years for a liability action).
