A judgment arrives, the ruling goes against you, and you search within the body of the decision for the specific reasons that led the judge to dismiss your arguments. If this search proves futile, it is likely because Article 455 of the Code of Civil Procedure has not been respected. This text requires the judge to restate the parties’ claims and to justify their decision, two requirements that condition the very possibility of contesting a judgment.
Failure to provide reasons: what concretely triggers a cassation
Article 455 is often thought of as a formal rule. In practice, it is a formidable lever for cassation. When a judge fails to respond to a point raised in the final submissions of a party, the Court of Cassation considers that the decision is tainted by a failure to respond to submissions.
On January 31, 2024, the commercial chamber annulled a ruling in a dispute concerning trademarks and products or services, precisely because the court of appeal had not responded to relevant submissions. This case shows that the obligation is not limited to general disputes: it applies with the same rigor in specialized areas such as intellectual property.
For an explanation of Article 455 of the Code of Civil Procedure focused on the text itself, reading the complete wording remains the starting point. The judgment must succinctly outline the respective claims of the parties and their arguments, then state the decision in the form of a ruling.
The sanction is not theoretical. Omitting a relevant point is enough to lead to cassation, without the aggrieved party having to demonstrate that the outcome would have been different. The flaw affects the very structure of the decision.

Citation of submissions: conditions and pitfalls of reference by citation
Article 455 allows a common practice in courts: instead of summarizing each party’s argument, the judge can cite their submissions by indicating their date. This technique is found under formulations such as “seen the submissions of X, dated…, to which reference is made in application of Article 455 of the Code of Civil Procedure.”
Two conditions frame this reference:
- The citation must mention the date of the submissions, in accordance with the text of Article 455 of the CPC.
- The citation must refer to the latest submissions of each party, as these define the subject of the dispute that the court must rule on.
- If the judge cites submissions prior to the latest writings, the judgment is at risk of cassation for violation of Article 455.
The Court of Cassation ensures that this procedural ease does not become a shortcut that undermines the obligation to provide reasons. A simple citation does not exempt the judge from responding to determining points. In other words, referring to submissions does not replace the need for substantive reasoning.
Word-for-word repetition of the first-instance writings
Another common pitfall on appeal: the court merely repeats the statement of facts and arguments as drafted by the first judges, without adding its own analysis. The Court of Cassation has ruled that this practice does not constitute reasoning within the meaning of Article 455. The appellate judge must formulate their own reasons, even if they arrive at the same conclusion.
Article 455 of the CPC and the right to a fair trial: the European dimension
The obligation to provide reasons is not solely based on the Code of Civil Procedure. It is linked to the right to a fair trial guaranteed by Article 6 of the European Convention on Human Rights. This dual anchoring, national and European, strengthens the oversight exercised over inadequately reasoned decisions.
In matters of enforcement of foreign decisions, the reasoning takes on particular importance. The French judge must be able to verify, upon reading the decision, that fundamental rights have been respected, for example, the consent of the individuals involved in a parentage case. Without readable reasoning, public order control becomes impossible.
Consequences for the lawyer drafting their submissions
From the practitioner’s side, Article 455 imposes a discipline of drafting. If a point is not clearly stated in the latest submissions, the judge does not have to respond to it. One cannot blame a lack of reasoning on an argument buried in a confusing development or absent from the submissions’ ruling.
In practical terms, each point that one wishes to have addressed must be:
- Formulated distinctly and identifiable in the body of the submissions.
- Included in the ruling as a specific request addressed to the court.
- Present in the latest submissions filed before closure, and not in earlier writings replaced in the meantime.
If any of these conditions are missing, invoking Article 455 in cassation will become difficult. The rigor of drafting the submissions directly conditions the effectiveness of the oversight of reasoning.

Practical implications of Article 455 for contesting a judgment
When receiving an unfavorable decision, the first useful reflex is to check whether each point raised in the latest submissions has received a reasoned response. The absence of a response on a determining point opens the way for a cassation appeal based on the violation of Article 455.
The nuance lies in the “determining” nature of the point. The Court of Cassation does not require the judge to respond to every detailed argument. However, any point that could influence the outcome of the dispute calls for a response. The boundary between a secondary argument and a determining point varies according to the nature of the dispute and the procedural configuration, making case-by-case analysis necessary.
Article 455 of the Code of Civil Procedure functions both as a guarantee for the parties and as a constraint for the judge. Mastery of it, both in terms of drafting submissions and in critical reading of the judgment, remains a concrete tool for anyone considering a recourse.
