Background
Giraud-Serin, a metalwork construction company, was part of a joint venture group awarded a lycée (secondary school) reconstruction project by the Midi-Pyrénées region (now Occitanie) in 2024. The common mandatary of the joint venture was Société nouvelle Thomas et Danizan Midi-Pyrénées (SNTD). When the project experienced delays, the public authority imposed delay penalties totaling approximately €5.5 million on the group, of which 78.3% (€4.3 million) was attributed to Giraud-Serin.
Giraud-Serin challenged the penalty allocation before administrative courts, arguing it was unfairly apportioned. In March 2021, the administrative appeals court rejected its claims and ordered it to pay the full amount to the region. Having exhausted administrative remedies, Giraud-Serin then sued SNTD in civil court, alleging that the mandatary had erred in calculating and distributing the penalties, thereby breaching their private contractual relationship.
SNTD moved to dismiss the civil action on jurisdictional grounds, contending that disputes over penalties arising from public works execution belong exclusively to administrative courts. The Toulouse Court of Appeal agreed and dismissed the case. Giraud-Serin appealed to the Court of Cassation.
The Court’s Holding
The Court of Cassation reversed the lower court, holding that civil courts do have jurisdiction to hear disputes between joint venture members over alleged contractual breaches in allocating penalties, provided certain conditions are met. The Court established that while disputes “arising from execution of a public works contract and opposing participants in the execution of those works” normally fall within administrative jurisdiction, an exception applies when the parties are united by a private law contract and the plaintiff’s claims concern only the performance of that private agreement.
Critically, the Court distinguished between two types of claims: (1) claims seeking to challenge or reassess the public authority’s penalty decision or requiring examination of overall project execution conditions, which remain within administrative jurisdiction; and (2) claims asserting that one group member breached its contractual obligations to another in applying or allocating penalties, which may be heard by civil courts. The Court found that Giraud-Serin’s suit fell into the second category because it: (a) did not challenge the public authority’s final allocation decision; (b) did not implicate the principle or reasoning behind the penalties themselves; and (c) only alleged that SNTD, as mandatary, had misapplied or miscalculated its share of the contractual obligation.
The Court concluded that the Toulouse Court of Appeal had violated the 1790 separation-of-powers statutes by failing to draw the proper legal conclusions from its own factual findings. The lower court had acknowledged that Giraud-Serin’s claims were grounded solely in contractual breach, not in challenge to administrative decisions, yet still dismissed the case as beyond civil jurisdiction.
Key Takeaways
- Civil courts may hear contractual disputes between members of a joint venture on a public works project, even though the underlying contract arose from public sector work, when the dispute concerns private law contractual breach and does not require reassessing the public authority’s administrative decisions.
- The critical distinction is whether the plaintiff is challenging the public authority’s decision (administrative matter) or alleging that a co-contractor breached the private agreement between them (civil matter).
- Group members have a civil law remedy against the mandatary for alleged errors in penalty allocation, provided the claim focuses on contractual performance rather than the validity or reasoning of the public authority’s original penalty determination.
- The separation-of-powers principle between administrative and civil courts does not automatically vest all disputes touching public works within administrative jurisdiction; the nature and scope of the claim governs.
Why It Matters
This decision clarifies an important boundary in French judicial system architecture. Public works contracts, which inherently involve public administration, have long been presumed to fall within administrative court jurisdiction. However, when multiple private entities contract as a joint group to perform public work, they create horizontal private law relationships among themselves that exist separately from their vertical relationship with the public authority. This ruling recognizes that disputes within the joint venture group, particularly when grounded in alleged contractual misperformance by the mandatary, can appropriately be resolved through civil courts without encroaching on administrative authority’s domain.
For practitioners, the decision is significant because it restores a civil law forum for intra-group disputes on public projects, allowing group members to pursue remedies for breach of the private agreements that govern their conduct. However, it also sets boundaries: any claim that implicitly requires the civil court to reassess the public authority’s decisions or the overall conditions of public project execution will still be deemed an administrative matter and rejected. Plaintiffs must carefully frame their claims to focus on the private contractual breach and avoid inviting judicial examination of the underlying public works contract’s execution or the public entity’s administrative determinations.
