Background
On February 6, 2023, an employee of the appellant company died in a “malaise mortel” (fatal incident). The primary health insurance fund of Côte-d’Opale classified the death as work-related and covered it under professional legislation. The employer contested this determination before the appellate court in Amiens, which ruled against it on November 27, 2025. Rather than pursue further factual arguments, the employer sought a constitutional referral.
Under Article L. 411-1 of the Social Security Code, accidents occurring at the time and place of work are presumed work-related. The employer must rebut this presumption by proving the accident had a cause entirely unrelated to work. The employer challenged this framework as unconstitutional, arguing that while autopsy reports—which could help rebut the presumption—are now excluded from administrative files due to medical confidentiality, the law still requires employers to disprove work-relatedness without guaranteeing access to necessary medical evidence. The employer contended this violated the constitutional right to an effective judicial remedy under Article 16 of the 1789 Declaration of the Rights of Man and of the Citizen.
The Court’s Holding
The Court of Cassation declined to refer the constitutional question to the Constitutional Council, finding the question lacked novelty and serious merit. Under French constitutional procedure, not all constitutional challenges proceed to the Constitutional Council; the Court of Cassation screens them first.
The court acknowledged the employer’s concern but held that employers do not face “structural impossibility” in accessing necessary medical information. Although autopsy reports are protected by medical confidentiality and need not be included in the administrative file, Article L. 142-6 of the Social Security Code (amended in 2019) ensures that the medical advisor must transmit the complete medical report—setting forth the examinations and findings underlying the coverage decision—to the friendly mediation commission. This report can be disclosed to a physician designated by the employer without violating medical confidentiality. Furthermore, when contesting whether an accident is work-related, an employer may request the social security court to appoint an expert with access to the complete medical file.
The court concluded that even if an employer fails to rebut the presumption—particularly when the cause of the accident remains unknown—this failure does not violate the constitutional right to an effective remedy. The legal framework provides employers adequate procedural and evidentiary tools; an unsuccessful defense on the merits is not a constitutional violation.
Key Takeaways
- France’s presumption that workplace accidents are work-related is constitutional; employers may rebut it but must prove a cause entirely unrelated to work.
- Medical confidentiality protections on autopsy reports do not prevent employers from accessing medical evidence through designated physicians or court-appointed experts.
- The exclusion of autopsy reports from administrative files does not create an insurmountable barrier to an employer’s defense, given alternative access mechanisms.
- A constitutional question will not be referred to the Constitutional Council if it lacks novelty or if existing law already adequately protects the rights in question.
Why It Matters
This decision clarifies the relationship between medical confidentiality and workplace accident litigation in France. Expanding medical confidentiality protections (particularly by excluding autopsy reports from administrative files) might initially appear to disadvantage employers defending against work-accident classifications. The court holds, however, that alternative mechanisms—medical reports transmitted through formal procedures and expert appointment by the court—provide adequate protections for employers’ rights to an effective remedy.
For employers and insurers, the ruling establishes that the legal framework does not violate constitutional rights despite denying direct access to autopsy reports. The decision encourages employers to utilize formal procedures: requesting the complete medical report through the friendly mediation commission and seeking expert appointment through the social security court. The court’s emphasis on these procedural safeguards signals that employers should pursue these channels when challenging the occupational classification of an accident.
