What the Action en Représentation Conjointe Is
The action en représentation conjointe was introduced before the action de groupe and operates on a fundamentally different premise. Where the class action allows an association to define and represent an abstract group of initially unknown consumers, the joint representation action requires that the consumers whose interests are to be defended be individually identified and that each of them have given the association a written mandate before proceedings begin.
The mechanism was designed to allow a consumer association to aggregate multiple individual claims against the same professional into a single set of proceedings — saving costs, reducing fragmentation of litigation, and giving each individual consumer access to the association's legal expertise. In practice, the mandate requirement has limited its uptake: organising written mandates from a significant number of consumers before filing is operationally demanding, and the action de groupe — which the loi Hamon introduced in 2014 without any mandate requirement — is generally preferred for mass harm situations. The joint representation action remains relevant where the pool of victims is small and already known, or where consumers are sufficiently organised to collectively grant mandates.
The Three Cumulative Conditions
The association must be approved (agréée) and recognised as nationally representative (Art. L 622-1). This is the same standing requirement as for the action de groupe and the other consumer association actions under Art. L 621-1. The seventeen nationally approved associations satisfy this condition.
The individual harms of the mandating consumers must have been caused by the acts of the same professional and must have a common origin. This is the causation link that justifies aggregating the individual claims: the same conduct, the same product, or the same contract type must be the common source of all the harm.
This mirrors the "similar or identical situation with a common cause" requirement of the action de groupe, but here it is verified by the mandates themselves rather than defined by the court.
The victims must be identified natural persons (physical persons — not legal persons), and at least two of them must have given the association a written mandate (Art. L 622-1). The written form is mandatory; verbal consent is insufficient.
This is the defining difference from the action de groupe: the consumers must exist and be identifiable before the proceedings begin, and they must actively mandate the association in writing before it can act for them.
The Critical Distinction from the Action de Groupe
- Written mandate required from each consumer before proceedings begin
- Consumers must be identified and known at the outset
- Minimum 2 mandating consumers required
- Association acts on behalf of named individuals
- Individual damages for each mandating consumer
- Any court: civil, criminal, or administrative
- Mandate revocable; action fails if < 2 mandants remain
- Limited practical use due to logistical demands of the mandate requirement
- No prior mandate required — association acts without consumer authority
- Group defined in the abstract — members unknown at outset
- No minimum consumer count at filing stage
- Association acts for an abstract group that self-constitutes via opt-in
- Individual patrimonial damages for each adhering consumer
- Tribunal judiciaire only
- No revocation mechanism; adhesion = mandate for indemnification
- Preferred mechanism for mass harm — introduced 2014 specifically to overcome mandate barrier
The action de groupe was introduced partly because the joint representation action had seen limited uptake due to the mandate requirement. But the two mechanisms are not identical in their available remedies and courts. The joint representation action can be brought before criminal, civil, and administrative courts, making it usable in contexts where the conduct constitutes a criminal offence or where an administrative body is the defendant. The action de groupe is limited to the tribunal judiciaire. Where a small group of identified consumers wishes to bring coordinated proceedings — and particularly in criminal or administrative contexts — the joint representation action retains practical relevance.
The Content of the Mandate
Procedural Rules
The action en représentation conjointe can be brought before any court — civil, criminal (including through civil party constitution), or administrative — depending on the nature of the underlying claim (Art. L 622-1). In criminal proceedings, the consumers who gave their mandate are treated as civil parties, but all notifications and service of process are addressed to the association rather than to each individual (Art. L 622-3).
The court's pecuniary jurisdiction and the threshold for last-resort jurisdiction are determined by the highest single claim among all the consumers' claims (Art. R 622-3). This ensures the proceedings are heard by a court with sufficient jurisdiction to deal with the most significant individual claim in the bundle.
All summonses and notifications for the consumer in the course of proceedings are addressed to the association acting on their behalf (Art. R 622-4). The association must in turn inform each mandant, by all appropriate means, of the court before which the matter is brought, the hearing date, and the date of judgment. On the mandant's request, the association must provide copies of the initiating act and written submissions, at the consumer's expense (Art. R 622-6).
The judgment is notified to the association, which must inform its mandants immediately and in any event within the appeal time limits. The time limit for exercising an appeal runs from the notification to the association — not to the individual consumers (Art. R 622-10). The association's receipt of the judgment is therefore the critical date for all appeal deadline purposes.
Revocation of the Mandate and Its Effects
Under general civil law, a mandate is revocable at any time by the person who gave it (Arts. 2003 et seq. of the Code civil). This principle applies fully to the mandate of joint representation. The effects of revocation in this context are as follows (Art. R 622-5):
- The consumer who revokes their mandate may continue the proceedings themselves, as if they had introduced the action directly. They must immediately notify the court and the opposing party
- If at least two mandants remain, the action en représentation conjointe continues
- If fewer than two mandants remain, the action en représentation conjointe can no longer proceed as such. The last remaining mandant may continue as an individual claimant
Association Dissolution or Loss of Approval
Where the association that initiated the action is dissolved, changes its objects, or loses its approval, the mandating consumers can always give their mandate to another nationally approved consumer association to continue the proceedings (Art. R 622-7). The action is not automatically extinguished by the initiating association's inability to continue — the mandate structure allows a successor association to take over.
The Four Consumer Association Actions Compared
| Feature | Action en Réparation Pénale (L 621-1) | Action en Cessation (L 621-7) | Action en Représentation Conjointe (L 622-1) | Action de Groupe (L 623-1) |
|---|---|---|---|---|
| Prior consumer mandate? | No | No | Yes — written, ≥ 2 consumers | No |
| Consumers identified at outset? | No | No | Yes — natural persons | No — defined in abstract |
| Remedies sought | Collective interest damages; cessation | Cessation; clause removal | Individual damages for each mandant | Individual patrimonial damages for each adhering consumer |
| Court | Civil or criminal | Civil (or référé) | Any court: civil, criminal, administrative | Tribunal judiciaire only |
| Criminal offence required? | Yes | No (EU-derived law breach) | No | No |
| If < 2 mandants / members? | N/A | N/A | Action cannot continue as joint representation | No equivalent rule; group not yet constituted at filing |
The action en représentation conjointe's limited uptake in practice stems directly from the need to obtain written mandates from individual identified consumers before filing. In mass harm situations — thousands of overcharged telecom subscribers, tens of thousands of credit card holders who paid an unlawful fee — collecting individual written mandates at scale before proceedings begin is logistically very difficult and costly for the association. The action de groupe resolves this problem entirely by requiring no prior mandate. The joint representation action therefore occupies a niche: small identified pools of consumers who are already organised, where the association can realistically obtain mandates before filing, or where the nature of the proceedings (administrative, criminal) means the action de groupe is not available.
The action en représentation conjointe sits alongside three other consumer association legal tools in a coherent framework of collective redress. Understanding which action is most likely to be deployed against your business in a given situation is the foundation of any effective risk management strategy.
