Incidental appeal: omission of the mention in the respondent's submissions does not render claims inadmissible

Analysis of a ruling Cass. com., July 8, 2026, n° 24-19.176, by Pierre-Louis Roquet, a business law avocat in Lyon.

A company and its director, a joint and several guarantor, lost their appeal case due to a missing heading. The bank had granted them a treasury loan of 250,000 euros in 2014; the director had committed up to 125,000 euros. Five years later, the bank sued the principal debtor and its guarantor for execution. The court of appeal condemned them. It did more: it declared the company's incidental appeal inadmissible and, consequently, its claims for damages against the credit institution.

The reason was a few words. The first conclusions d'intimé (respondent's submissions), filed on October 25, 2023, within the three-month period of Article 909 of the French Code of Civil Procedure, did not include the mention "incidental appeal". However, in the dispositif (operative part), they requested the reversal of the judgment insofar as it had dismissed the company's claims for damages against the bank. The court ruled that the incidental appeal had therefore not been filed within the deadline. The reproach addressed to the bank disappeared with the missing heading.

The Commercial Chamber quashed the decision. It did so soberly, without invoking the right to a remedy or Article 6 § 1 of the European Convention on Human Rights, which the appeal invoked under the excessive formalism. Three texts sufficed: Articles 542, 909, and 954, paragraphs 2 and 3, of the French Code of Civil Procedure.

The law has never required a paragraph titled "incidental appeal"

The reasoning reads like a literal interpretation, which is its strength. Article 542 states that an appeal aims, by criticizing the judgment, at its reformation or annulment. Article 909 imposes on the intimé (respondent), under penalty of inadmissibility raised ex officio, a three-month period from the notification of the appellant's submissions to file their submissions and, if applicable, to lodge an incidental appeal or a provoked appeal. Article 954 organizes the structure of legal briefs: statement of facts and procedure, statement of criticized parts of the judgment, discussion of claims and arguments, and a dispositif (operative part) summarizing the claims. The court rules only on the claims stated in the dispositif and examines arguments only if they are invoked in the discussion.

The Court then identifies the purpose of this dispositif: to ensure clarity and readability of the parties' briefs. Nothing more. From this purpose, it deduces what the texts do not require. They do not require that the claims and arguments of the incidental appeal formally appear under a paragraph titled "incidental appeal". Nor do they require these terms to appear in the dispositif of the respondent's submissions.

The phrase that concludes the quashing is one that every appellate litigator knows and dreads when it works against them: the court of appeal "added a condition to the law that it does not provide". The procedural sanction is a textual sanction. It is not deduced from a usage, a reading convenience, or a drafting preference.

The operative part is sufficient, provided it requests reversal within the deadline

What the commercial chamber retains as useful is simple and verifiable: in the dispositif of its first submissions filed within the period of Article 909, the company requested the reversal of the judgment insofar as it had dismissed its claims for damages. This request for reversal is the incidental appeal. It carries its substance, since it criticizes the judgment and seeks its reformation on a specific point. The label is irrelevant.

The ruling thus falls within the movement of retreat of procedural formalism that has been traversing appellate procedure for several years. The second civil chamber laid the groundwork by requiring that inadmissibilities be based on a textual requirement and not on a pretorian reconstruction. The commercial chamber extends this line in banking litigation, with an immediate patrimonial consequence: the guarantor and the debtor regain the possibility of having their claims against the bank heard before the referral court of appeal, differently constituted. The second ground, however, was not specifically motivated, in application of Article 1014, paragraph 2, of the French Code of Civil Procedure.

The quashing is partial. It maintains the condemnation to pay 125,000 euros in principal, pronounced jointly and severally. What is revived is the indemnification aspect.

What the ruling does not exempt from doing

Care must be taken not to read into it a general amnesty. The three-month period of Article 909 remains imperative and is sanctioned by inadmissibility raised ex officio. The claim must always be formulated in the dispositif, otherwise it will not be examined. The arguments supporting it must be articulated in the discussion, and presented distinctly when they are new compared to previous briefs. The ruling shifts the focus to the heading, not the architecture.

The Decree n° 2023-1391 of December 29, 2023 simplifying civil appeal procedure has revised Article 954 for appeal proceedings initiated from September 1, 2024. The ruling of July 8, 2026, rules on the previous version, applicable to submissions from October 2023. The transposition nevertheless seems assured: the logic of the summary dispositif and the discussion carrying the arguments survives the reform, and the Court's reasoning is based on the purpose of the texts, not on their contingent letter. The conseiller de la mise en état (judge in charge of case management) moreover retains the power to enjoin lawyers to conform their submissions, which constitutes the normal way to correct an imperfect brief.

Several questions remain open. The ruling does not say what happens to respondent's submissions whose dispositif merely requests confirmation of the judgment, with the claim for damages only appearing during discussion or in subsequent briefs. It does not decide the fate of a provoked appeal directed against a non-appellant party. It does not exempt from stating the criticized parts of the judgment. Finally, it says nothing about the hypothesis where the dispositif requests a reformation without identifying the targeted part of the judgment.

There remains the advice of prudence, which has not changed. Nothing prevents writing "incidental appeal" at the head of a dedicated section and repeating these terms in the dispositif. It remains preferable to do so. In our practice before the Lyon Court of Appeal, a brief that announces its incidental appeal, lists the criticized parts, and summarizes each claim in the dispositif spares both the conseiller de la mise en état and the collegiate panel the work of qualification. Above all, it avoids an appeal to the Cour de cassation. Winning in the Cour de cassation on a missing heading is a costly victory: two years of procedure, a referral, and a waiting client.

Frequently Asked Questions

Do my respondent's submissions have to expressly mention the incidental appeal?

No, the law does not require it. The commercial chamber rules that neither a paragraph titled "incidental appeal" nor the presence of these terms in the dispositif conditions admissibility. It is sufficient for the dispositif of the first submissions, filed within the period of Article 909, to request the reversal of the judgment on the part concerned. The mention is nevertheless recommended as a simple drafting precaution.

Is the three-month period of Article 909 relaxed by this ruling?

In no way. The intimé (respondent) still has three months from the notification of the appellant's submissions to file their own and, if applicable, lodge an incidental appeal or a provoked appeal. Inadmissibility is raised ex officio. The ruling merely accepts that the request for reversal appearing in the dispositif within this period constitutes an incidental appeal.

What happens if the operative part only requests confirmation of the judgment?

The ruling does not address this hypothesis, but prudence dictates treating it as perilous. The court rules only on the claims stated in the dispositif. A purely confirmatory dispositif criticizes no part of the judgment and therefore contains no request for reformation that could be qualified as an incidental appeal.

Does a claim for damages against the bank require an incidental appeal?

Yes, when the first judge rejected it and the condemned party is the intimé. The claim for damages then criticizes a part of the judgment and falls under the mechanism of an incidental appeal, with the accompanying three-month period. This is precisely the pitfall on which the company had foundered before the court of appeal.

Does the Decree of December 29, 2023, change the solution?

It revised Article 954 for appeal proceedings initiated since September 1, 2024, whereas the ruling applies to the previous version. The solution appears transposable because it is based on the purpose of the texts, namely the clarity and readability of the briefs, and not on a precise formulation. The dispositif and discussion architecture remains unchanged.

What to do if already filed submissions are imperfect?

You should seize the first opportune moment to regularize through recapitulative submissions, within the applicable deadlines, and not wait for the hearing. The conseiller de la mise en état can enjoin lawyers to conform their briefs to Articles 954 and 960. It is better to seek this regularization than to later defend against an inadmissibility.

What is the practical scope before the Lyon Court of Appeal?

An immediate impact in banking litigation and security law, where counterclaims by the guarantor and the principal debtor often play out at the appeal stage. The ruling secures briefs whose heading is imperfect but whose dispositif is complete. It does not exempt from rigorous drafting, which remains the best protection for the client.
