Civil party in co-ownership: the syndic's authorisation must precede the judgment

Imagine: you own a flat in Saint-Doulchard, and your co-owners' association files a complaint against a neighbour for nuisance. The syndic acts without having received the green light from the general meeting. The criminal court declares the constitution of civil party inadmissible. Can it be regularised on appeal? The Court of Cassation says no, and this 2007 decision is still relevant today.

The question that every co-owner asks: can my syndic take legal action without my consent? And if not, how should I react?

This decision of 14 March 2007 (No. 06-84.320) recalls a fundamental principle: the rule of double degree of jurisdiction prohibits regularising a constitution of civil party that was inadmissible at first instance on appeal. In other words, if the syndic was not authorised on the day he acted before the criminal court, it is too late to obtain retrospective authorisation.

The facts: a story that happens every day

Mr X, a resident of Aubigny-sur-Nère, has been suffering from water infiltration from the neighbouring flat for months. The co-owners' association, represented by its syndic, decides to become a civil party (i.e., to claim damages before the criminal court) against the neighbour for breach of the co-ownership regulations. The syndic acts without having obtained prior authorisation from the co-owners' general meeting.

At first instance, the criminal court finds that the syndic had no authorisation (special power) to become a civil party on behalf of the association. It therefore declares the action inadmissible. The association appeals.

On appeal, the court of appeal finds that in the meantime, a general meeting passed a resolution authorising the syndic to act. It considers this regularisation valid and declares the constitution of civil party admissible. But the Court of Cassation quashes this judgment: it recalls that the rule of double degree of jurisdiction (the principle that a case is judged twice, on fact and on law) prohibits regularising an inadmissibility after the first instance judgment.

The reasoning of the court — dissected

The Court of Cassation relies on a fundamental principle of procedure: the double degree of jurisdiction. This principle guarantees that each case is examined by two different courts (first instance and appeal). But it also implies that the appeal cannot remedy a nullity or inadmissibility that occurred at first instance. In short, if the syndic did not have the power to act before the criminal court, the irregularity is final.

The legal basis is Article 122 of the Code of Civil Procedure (which lists grounds of inadmissibility), but also the Law of 10 July 1965 on co-ownership (Article 55): the syndic cannot take legal action without authorisation from the general meeting, except in cases of urgency. Here, there was no urgency, and the authorisation came too late.

What few people know: the Court of Cassation had already ruled similarly in a decision of 6 December 2005 (No. 04-86.547), confirming a consistent line of case law. The appeal judges had tried to circumvent the rule by considering that the general meeting decision after the judgment regularised the lack of authority. But the Court of Cassation refuses this "regularisation by appeal".

What this means for you — practically

For the co-owner: if your syndic initiates legal proceedings without authorisation from the general meeting, you can challenge those proceedings at first instance. If you let the judgment pass, it will be too late to regularise on appeal. Example: in Saint-Doulchard, an association lost €5,000 in legal costs because the authorisation to bring proceedings was only voted after the judgment.

For the syndic: you must imperatively obtain a general meeting decision before acting. In case of urgency, you can apply to the President of the Judicial Court for provisional authorisation (Article 55 of the 1965 Law).

For the landlord owner: if you are sued by an association, check whether the syndic was duly authorised. If not, raise the inadmissibility at first instance. Caution: this ground must be raised before any defence on the merits.

Four tips to avoid this type of dispute

• Check the syndic's mandate before any action: ask for a copy of the general meeting resolution authorising the syndic to act. Keep it in your files.
• In case of urgency, request authorisation from the President of the court: Article 55 of the 1965 Law allows the syndic to apply to the interim relief judge for provisional authorisation. This is a quick procedure (a few days).
• If you are being sued, raise the lack of authority from the outset: in your first submissions, mention that the syndic has no authorisation. Otherwise, you risk losing this argument.
• Have a general authorisation voted each year: the general meeting can give a general mandate to act against certain types of disturbances (nuisance, unpaid debts). This avoids last-minute regularisations.

Further reading: related case law and developments

The Court of Cassation has confirmed this position in several subsequent decisions. For example, in a decision of 16 March 2004 (No. 03-84.541), it held that the syndic cannot become a civil party without prior authorisation, even if the general meeting approves it afterwards. In a decision of 20 January 2009 (No. 08-84.502), it specified that the authorisation must be special (i.e., mention the specific case) and not general.

This case law is consistent. It means that appeal courts cannot "remedy" procedural errors made at first instance. For co-owners, this is a protection: it forces syndics to be rigorous. But it also imposes increased vigilance: if the syndic forgets to request authorisation, the action is definitively lost.

Summary and next steps

FAQ:

• What should I do if my syndic takes action without authorisation? Ask him for proof of authorisation. If he cannot provide it, apply to the enforcement judge or the Judicial Court to have the inadmissibility declared.
• Can I regularise the authorisation during the proceedings? Yes, but only before the first instance judgment. After that, it is too late.
• What are the deadlines to challenge? You must raise the inadmissibility before any defence on the merits, i.e., in the first submissions. In practice, as soon as you receive the summons.
• How much does an urgent authorisation procedure cost? Expect around €500 to €1,500 in lawyer's fees for an interim relief application, depending on complexity.
• What does the syndic risk if he acts without authorisation? His constitution of civil party will be declared inadmissible, and the association may be ordered to pay the costs (legal fees).
