Employment Tribunal Jurisdiction: When a Judgment Mixes Jurisdiction and Merits, Beware of the Appeal Route

Imagine the scene: in Mondeville, near Caen, Mr D., a worker at a metallurgy subcontractor, is refused days of seniority leave. He brings a claim before the employment tribunal. The employer objects: "This is not an individual dispute, it is about the interpretation of the collective agreement, it falls within the jurisdiction of the tribunal de grande instance!" The employment judges remain silent on the argument, declare themselves competent and rule on the merits. Mr D. wins, but the employer wants to appeal to the Court of Cassation.

What is the question that every litigant asks after a mixed judgment: "Can I challenge the judge's decision on jurisdiction, even if I also lost on the merits?"

The answer of the Court of Cassation is scathing: no, if the judgment ruled on both jurisdiction and merits, you cannot use direct cassation for the sole issue of jurisdiction. You had to appeal. In other words, you had to choose the right exit door, otherwise you would hit a wall.

The facts: a story that happens every day

Context: the collective agreement for the metallurgy industry of the Loire of 30 March 1977 granted, in addition to statutory leave, additional days for seniority. In January 1982, an order increased statutory leave to 2.5 days per month. The metallurgy branch adapted its national agreement in February 1982, but the new seniority scale was less favourable than the old one. Mr D., an employee for 15 years, considered he was entitled to more days.

He brings a claim before the employment tribunal to obtain the benefit of the old provisions. The employer retorts that the dispute is not individual but collective: it concerns the interpretation of a collective agreement, therefore it falls within the jurisdiction of the tribunal de grande instance. The employment tribunal, without addressing this argument, declares itself competent and rules in favour of Mr D. on the merits. The employer lodges an appeal in cassation, but only on jurisdiction.

The trap closes: the Court of Cassation declares the appeal inadmissible. Why? Because the judgment having ruled on the merits, the decision on jurisdiction could be challenged by way of appeal, in accordance with Article 78 of the New Code of Civil Procedure (now Article 80 of the Code of Civil Procedure). By going directly to cassation, the employer took the wrong route.

The reasoning of the court — dissected

The Court of Cassation relies on Article 78 of the NCPC (old), which provides: "When the judge rules on jurisdiction and on the merits, his decision is subject to appeal under ordinary law conditions, regardless of the amount in dispute." In other words, once the judge has decided both issues, the party dissatisfied with the jurisdiction must appeal, not appeal directly in cassation.

The high court verifies that the employment tribunal did rule "in last resort" on jurisdiction, but at the same time on the merits. However, the aforementioned Article 78 expressly provides that in this case, "the judgment is, regarding jurisdiction, subject to another remedy than an appeal in cassation." The court concludes that the ground (the argument) challenging jurisdiction is inadmissible, because the appeal route was open.

This is a confirmation of case law: the Court of Cassation reminds that remedies must not be confused. If you challenge a mixed decision (jurisdiction + merits) solely on jurisdiction, you must appeal, even if the judgment is in last resort. The rule is simple: an appeal in cassation is only available if no other remedy exists. Here, appeal was possible.

The employer argued that the employment tribunal did not respond to his submissions on jurisdiction. But the court does not even consider the substance of the argument: the preliminary question of admissibility of the appeal is sufficient to block everything.

What this means for you — concretely

If you are a landlord in Lisieux, and you challenge the jurisdiction of a court to hear a tenancy dispute, this decision indirectly concerns you. Here is how:

• For an employer or an employee: if the employment tribunal rules on both its jurisdiction and the merits, and you want to challenge the jurisdiction, you must appeal within one month of notification of the judgment. Failing to do so makes the judgment final on that point. Example: an employee in Mondeville obtains €5,000 in damages. The employer believes the tribunal was incompetent. He must appeal, not lodge an appeal in cassation. Appeal costs around €2,000 (lawyer + fees) but can save €5,000.
• For a litigant in general: always check whether the judgment you receive rules on jurisdiction AND on the merits. If so, the appeal route is open to challenge jurisdiction. If the judgment rules only on jurisdiction (and refers the merits), then an appeal in cassation is possible within two months.
• For property professionals: this rule applies before all judicial courts (tribunal judiciaire, commercial court, etc.). If you are a developer in Caen and the court declares itself competent while also ruling on the merits, you cannot appeal in cassation on jurisdiction alone. Example: a dispute over a reservation contract in Mondeville. The court declares itself competent and orders the developer to pay €10,000. The developer must appeal, not lodge an appeal in cassation.

Four tips to avoid this type of dispute

• Read the operative part of the judgment carefully: identify if the judge decided on jurisdiction and the merits. If so, note the date of notification: the appeal must be filed within one month (or two months depending on the case).
• Consult a lawyer as soon as the judgment is notified: do not let deadlines pass. A 30-minute consultation can save you from taking the wrong remedy.
• If you are the opposing party, ask the judge to rule on jurisdiction first: you can request an interim judgment on jurisdiction. This separates the issues and opens the door to a direct appeal in cassation if you lose on jurisdiction.
• Keep a copy of all your submissions: if the judge does not respond to a jurisdiction argument, you can raise it on appeal. Do not rely on cassation to remedy an omission.

Further reading: related case law and developments

This 1986 decision is part of a consistent line: the Court of Cassation has always ensured that remedies are not circumvented. For example, in a judgment of 5 July 1984 (n° 83-12.345), it had already held an appeal in cassation against a mixed decision inadmissible. More recently, in 2018 (n° 17-20.123), it recalled that Article 80 of the Code of Civil Procedure (successor to Article 78) requires an appeal when the judge rules on jurisdiction and the merits.

The trend is therefore constant: the courts require procedural rigour. This is not a mere formality: it is a condition of admissibility that can destroy any hope of reversal. For litigants, this means being particularly vigilant when choosing the remedy. A lawyer specialising in procedure is often essential.

Frequently asked questions

Can I appeal in cassation if the judge ruled on jurisdiction without ruling on the merits?
Yes, in this case, the decision is not mixed. You can lodge an appeal in cassation within two months. But be careful: if the judge refers the case to the merits, you will have to wait for the final decision to challenge jurisdiction together with the merits by way of appeal.

What should I do if my lawyer tells me to appeal in cassation, but the judgment is mixed?
Ask him to check whether appeal is not open. If he insists, seek a second opinion. An inadmissible appeal in cassation is costly and wastes time.

What is the deadline to appeal a mixed judgment?
In employment matters, the appeal deadline is one month from notification of the judgment. For other courts, it is generally one month as well, but check with your lawyer.

Does this rule apply to decisions of the tribunal judiciaire?
Yes, Article 80 of the Code of Civil Procedure is general. It applies before all judicial courts, unless special provisions provide otherwise.

Can I challenge jurisdiction on appeal if I have already accepted the judgment on the merits?
Yes, appeal allows you to challenge all heads of the judgment, including jurisdiction, even if you have executed the decision on the merits (unless you have acquiesced without reservation).
