Background
ICTS France assumed the airport security contract at Beauvais airport on June 1, 2024, replacing Securit’air. M. [X], who had served as a union delegate for Force Ouvrière since 2018 while at Securit’air, had his employment contract transferred to ICTS France under French labor law provisions governing business transfers. On June 3–5, 2024, two separate union entities designated delegates for the Beauvais site: the FO ICTS union designated M. [K] on June 5, while the Union départementale Force ouvrière designated M. [X] on June 3 (received June 27). ICTS France sought to annul both designations, arguing that the transferred operation had lost organizational autonomy and therefore existing union mandates should not continue.
The trial court (tribunal judiciaire de Beauvais, October 24, 2024) rejected the company’s challenge, holding that M. [X]’s mandate subsisted and upholding both designations. ICTS France appealed to the Court of Cassation on two grounds: first, that the trial court improperly assigned the burden of proving loss of autonomy to the employer; and second, that the trial court failed to resolve the conflict between the two competing union designations.
The Court’s Holding
The Court of Cassation partially quashed the judgment on two separate grounds. First, regarding the continuation of union mandates after a business transfer: Under Article L. 2143-10 of the French Labor Code, a union delegate’s mandate continues after a change in the employer’s legal status (such as a contract transfer) only if the transferred enterprise or establishment maintains its organizational autonomy. Drawing on EU law principles established in the CJEU’s UGT-FSP decision, the Court clarified that autonomy requires the transferred entity’s managers to retain substantial decision-making powers—specifically the ability to organize work, give orders and instructions to subordinate workers, assign tasks, and allocate material resources, all without direct intervention from central management. The trial court violated this principle by placing the entire burden of proof on the employer to demonstrate loss of autonomy. Instead, the judge must form an independent judgment based on all evidence presented by both parties regarding whether the transferred entity maintained such substantive autonomy.
Second, regarding competing union designations: The Court held that when multiple unions designate more representatives than the law permits for a single establishment, the court must resolve the conflict by applying statutory rules determining which union has authority to designate, or by applying the chronological rule (first designation prevails) if no statute addresses the hierarchy. The trial court violated this obligation by refusing to adjudicate the conflict between the two June 3–4 designations, wrongly reasoning that because the company did not seek to annul M. [K]’s designation and the union did not contest the conflict itself, the court had no duty to decide. The Court reaffirmed that judges cannot remain passive when confronted with surnumerary (excessive) designations; they must actively resolve which designation is valid.
Key Takeaways
- After a business transfer, determining whether a union delegate’s mandate continues requires courts to independently evaluate whether the transferred entity retained autonomy, not merely to accept employer claims; the burden cannot rest solely on the employer to prove autonomy was lost.
- When multiple unions designate more delegates than legally permitted, courts must apply statutory rules or chronological order to determine which designation is valid, regardless of whether the employer contests all designations or only some.
- French law protects union representation continuity during business transfers consistent with EU Directive 2001/23/EC, while requiring courts to actively investigate facts rather than passively adjudicate conflicting claims.
Why It Matters
This decision addresses two recurring issues in French employment law: the treatment of union representation during business transfers (outsourcing) and the resolution of disputes when multiple unions exceed numerical limits on delegate designations. By reversing the burden of proof, the Court prevents employers from using opaque corporate structures to effectively eliminate union representation by demanding impossible proof of lost autonomy. Instead, courts must scrutinize whether management functions remained substantially unchanged at the transferred worksite—an objective inquiry into facts rather than an agreement or presumption favoring the new operator.
Equally important, the ruling clarifies that courts cannot defer resolution of competing union designations by claiming neutrality or lack of standing. This prevents cynical scenarios where one union designates a delegate and the employer challenges it while another union’s designation proceeds unchallenged, creating ambiguity about representation. The decision reflects a principled approach to enforcing both worker protections (mandate continuity in transfers) and procedural fairness (resolving competing claims according to law), aligning French practice with EU standards while empowering judges to investigate the economic reality of transferred operations rather than accepting surface characterizations.
