Nullity of a Municipal Sale: Apparent Authority Does Not Save the Purchaser

Imagine: you are a property owner in Écully, and you find an advertisement for a building plot put up for sale by the commune. The price is attractive, the mayor has signed the deed, everything seems in order. You sign, you pay… and a few months later, a judge annuls the sale because the municipal council resolution was void. You have lost your land and your money. Unfair? Yet, the justice system tells you: the commune was not bound by appearances. This is exactly what the Court of Cassation decided in a judgment of 16 June 2016. But what does it mean for you? Let's break it down.

The facts: a story that happens every day

A commune sells several plots of land to a property developer. The mayor signs the sale deed pursuant to a municipal council resolution. But this resolution is challenged before the administrative court, which declares it null and void. The developer, who had already paid the price and started works, finds himself without a title. He sues the commune for performance of the sale, arguing that the mayor had apparent authority: to a third party acting in good faith, everything seemed regular. The Lyon Court of Appeal (within the jurisdiction of the decision) rejects his claim. The developer appeals to the Court of Cassation. The Court of Cassation confirms: the theory of apparent authority (which protects the contracting party acting in good faith where the appearance of authority is created by the representative) does not apply to acts of local authorities. Why? Because the validity of the act depends on the regularity of the resolution, and the purchaser is supposed to verify that regularity.

The reasoning of the court — explained

The Court of Cassation relies on the principle of legality of administrative acts. It recalls that the mayor can only bind the commune within the limits of the powers conferred by a valid resolution. If the resolution is annulled, the authorisation given to the mayor disappears retroactively (as if it had never existed). Consequently, the sale contract is void. The apparent authority, provided for in Article 1156 of the Civil Code (former), cannot be invoked because it presupposes that the appearance was created by the principal itself (here, the commune). However, it is the mayor who created the appearance, but the commune had nothing to do with it: it did not ratify the act. In short, the developer should have checked that the resolution was final (unchallenged) before signing. This is not an injustice: it is the rule to protect public funds. In other words, the Court confirms settled case law: no apparent authority for legal persons governed by public law.

What this means for you — practically

For the purchaser of a communal asset: you must absolutely require a final resolution, i.e., one no longer subject to challenge (2-month period after publication). If the resolution is challenged, do not sign before the administrative court's decision. Example: in Vénissieux, an investor bought a commercial premises sold by the town hall. The resolution was annulled for procedural defect (lack of publicity). He lost his purchase and had to return the keys. With no possibility of recourse against the commune.

For the seller (commune): this decision protects you against claims from unfortunate purchasers. But it requires you to be irreproachable on procedure. A poorly drafted resolution can be costly: the property remains unsold, and the purchaser may claim damages on the basis of fault liability (Article 1240 of the Civil Code).

For the property professional: be vigilant when dealing with communes. Check the date of the resolution, its publication, and the absence of challenges. undefined, I have seen cases where the estate agent reassured the purchaser by saying "everything is in order"… and the sale was annulled six months later.

Four tips to avoid this type of dispute

• Require a final resolution: ask for a certificate of non-challenge issued by the commune, attesting that the 2-month period has elapsed without contestation.
• Use a specialised lawyer: before signing, a public law lawyer will verify the legality of the resolution (competence, form, reasons).
• Include a suspensive condition: in the preliminary sale agreement, provide that the sale is conditional upon confirmation of the validity of the resolution by the administrative court or upon expiry of the challenge period.
• Consult the register of resolutions: do not hesitate to go to the town hall to consult the register and verify that the resolution was properly adopted and published.

Further reading: related case law and developments

This judgment is part of a consistent line: the Court of Cassation systematically refuses apparent authority to local authorities (Civ. 1re, 9 June 1998, No. 96-18.372; Civ. 3e, 13 April 2005, No. 04-10.612). However, the Conseil d'État sometimes admits the commune's liability for fault if the purchaser was misled by a wrongful act (CE, 28 July 2000, No. 202.950). But the nullity of the contract remains. Since 2016, no major evolution: the rule is stable. What this means for the future: purchasers must be extra cautious, and communes must secure their procedures.

Frequently asked questions

• Can I obtain damages if the sale is annulled? Yes, if you prove a fault by the commune (e.g., failure to inform). But the contract itself is void, you cannot require the sale.
• What should I do if I have already signed and the resolution is challenged? Consult a lawyer immediately. You may try to regularise the resolution if the defect is minor, or negotiate compensation.
• What is the time limit to challenge a resolution? 2 months from its publication or notification. After this period, it becomes final.
• Can the mayor bind the commune alone? No, except in cases of urgency and within the limits of his own powers. For a sale, a resolution is mandatory.
• Does this rule apply to sales by public establishments (EPA, SEM)? Yes, the same logic applies to legal persons governed by public law.
