Why a Simplified Procedure Was Needed
The standard action de groupe was designed for situations of mass consumer harm where the individual victims are not yet known when proceedings begin: the group is defined in the abstract by the court's first judgment, and consumers then identify themselves through the opt-in adhesion window. That architecture makes sense for product liability cases, misleading commercial practices, or overcharging schemes where the harm is dispersed across a large, anonymous population of buyers.
But it is an unnecessarily complex apparatus when the victims are already identified and their harm is quantifiable on a uniform basis — for example, where a financial institution has charged all customers with account type X an unlawful fee of a fixed amount, the names and account details of those customers are known, and the harm suffered by each is the same. Article L 623-14 of the Code de la consommation creates the simplified action de groupe for exactly this situation: where the identity and number of the affected consumers are known and the harm is of a uniform or calculable amount.
The Three Triggering Conditions
Article L 623-14 requires three conditions to be simultaneously satisfied before the simplified procedure is available. If any one is absent, the standard procedure applies.
The individual consumers who have suffered the harm must already be identifiable at the time of the court proceedings. This typically arises where the professional holds records identifying the affected customers — for example, account holders, subscribers, or purchasers of a specific product batch. The association does not need to have identified each consumer themselves before filing; what matters is that by the time the court rules, the individuals can be named.
In practice, the association may have obtained the list of affected consumers from prior individual proceedings, from regulatory investigations, or from data the professional is ordered to produce during the proceedings.
Not only must the consumers be identifiable, but their number must be known at the time of the judgment. This condition works together with the identity condition: where the professional's records can be used to define a closed population of affected customers (e.g., all customers billed a specific unlawful charge), both conditions are typically met together.
The fact that the number is known does not mean it must be small. The simplified procedure is available regardless of the size of the consumer population, provided all three conditions are met. A class of tens of thousands of customers can qualify if their identity is known and their harm uniform.
The consumers must have suffered harm of a single identical amount, an identical amount per service rendered, or an identical amount calculated by reference to a given period or duration. This three-part formulation covers the main patterns of mass-uniform harm: a flat overcharge applied to all; a per-transaction overcharge applied uniformly; or a periodic overcharge applied over a defined period.
The common thread is uniformity of calculation: the same formula applies to all consumers, even if individual totals differ based on volume or period. What is excluded is harm that varies case by case and requires individual assessment.
Even where all three conditions are met, Article L 623-14 uses the word « peut » (may): the court has a discretion whether to apply the simplified procedure. If the court considers that the circumstances make the standard procedure more appropriate despite the conditions being met, it may proceed by the standard route. In practice, the simplified procedure is expected to be used whenever the conditions are satisfied and there is no compelling reason to revert to the standard process, but businesses should not treat the simplified procedure as a right that the association or the court is bound to apply.
The Simplified Procedure: Four Stages
The simplified action de groupe has four operative stages after liability is established: the court renders a direct condemnation; the professional notifies each consumer individually; the consumer must accept; and if the professional does not pay accepting consumers, the court resolves the non-execution.
After ruling on liability, the court directly condemns the professional to indemnify each identified consumer individually, within a deadline and according to modalities it must specify. There is no abstract group-definition phase, no public information campaign before the judgment, and no opt-in adhesion window of the standard type. The compensation amount for each consumer is calculable from the judgment itself.
Before execution and once the judgment is no longer subject to ordinary challenge or pourvoi en cassation, the professional must implement individual information measures for each affected consumer, at the professional's expense. The purpose is to allow each consumer to accept the compensation proposed. The judgment fixes the deadline and modalities.
The mandatory content of the individual information (Art. R 623-12) mirrors the standard procedure's information campaign requirements, but is addressed to each individually identified consumer rather than to the public at large. It must include: the operative part of the judgment; contact details for acceptance; the form, content, and deadline for acceptance; the warning that non-acceptance forecloses class action compensation; and the warning that acceptance bars subsequent individual action for the same compensated harm.
Each consumer who wishes to be compensated must expressly accept the compensation proposed in the judgment, by any means providing written acknowledgment, within the deadline and modalities set by the judgment. Acceptance must be sent to both the professional and the association. It must contain: the consumer's name, first name, and address; and an express statement of the compensation amount accepted.
Acceptance constitutes a mandate to the association for indemnification purposes, under the same rules as apply to the standard procedure (Art. R 623-15 cross-referencing Arts. R 623-20 to R 623-22). The mandate is revocable; revocation constitutes withdrawal from the group.
Consumers who do not accept within the deadline are permanently foreclosed from seeking compensation within the class action and are not represented by the association (Art. R 623-14). However, they are not prevented from bringing their own individual actions.
If the professional fails to pay consumers who have accepted the compensation within the court-set deadline, the court that ruled on liability resolves the difficulty (Art. L 623-16, cross-referencing Art. L 623-19). As in the standard procedure, the court rules on all unsatisfied claims in a single judgment (Art. R 623-10). If the professional then fails to execute that second judgment voluntarily, the association represents the non-compensated consumers in enforcement proceedings — the mandate for this purpose is deemed given by the consumers' acceptance (Art. L 623-16, cross-referencing Art. L 623-20).
Standard vs. Simplified: The Procedural Differences
| Feature | Standard action de groupe | Simplified action de groupe |
|---|---|---|
| Identity of consumers at commencement | Unknown — group defined abstractly by first judgment | Known before or established at judgment stage |
| Number of consumers | Unknown until adhesion window closes | Known at judgment stage |
| Harm amount | May vary across consumers; framework set by first judgment | Must be identical, identical per service, or identical per period |
| First judgment content | Liability + abstract group definition + harm framework + information measures + adhesion window | Liability + direct individual condemnation to compensate each identified consumer |
| Group constitution phase | Public information campaign + 2–6 month opt-in adhesion window | None — replaced by individual information after judgment |
| Consumer information timing | After exhaustion of all appeals; public channels (press, web, SMS) | After exhaustion of all appeals; individually addressed to each known consumer (Art. L 623-15) |
| Consumer response required | Opt-in adhesion (2–6 months) | Individual acceptance of the compensation (Art. R 623-13) |
| Acceptance = mandate? | Yes — adhesion vaut mandat (Art. L 623-9) | Yes — same rules apply (Art. R 623-15 cross-refs R 623-20 to R 623-22) |
| Non-acceptance consequence | Consumer loses class action right; individual action still possible | Same — no class action compensation; individual action still possible (Art. R 623-14) |
| Appeal procedure | Bref délai (Art. R 623-4) | Bref délai (Art. R 623-4) — same |
| Non-execution remedy | Second judgment by same court; association enforces (Arts. L 623-19 to L 623-21) | Same court resolves; association enforces via mandate implied from acceptance (Art. L 623-16) |
| Information campaign costs | Borne by professional; association implements on default | Borne by professional; individual notification format |
| Caisse des dépôts deposit | Mandatory for sums received by association (Art. L 623-10) | Same rules apply |
| Key articles | L 623-4 to L 623-13; R 623-8 to R 623-29 | L 623-14 to L 623-16; R 623-12 to R 623-15 |
The Critical Consequences of Acceptance and Non-Acceptance
What Acceptance Does
When a consumer accepts the compensation proposed in the simplified judgment, acceptance has two key effects: it constitutes a mandate to the association for indemnification purposes (covering all procedural acts and appeals, with the association advancing costs), and it operates as a bar to subsequent individual action against the professional for the same harm that has been compensated within the class action. The consumer retains the right to pursue individual proceedings for any harm outside the scope of the compensated claim — for example, for personal injury or moral harm not covered by the class action (Art. L 623-29).
What Non-Acceptance Does
A consumer who fails to accept within the court-set deadline and modalities loses their entitlement to class action compensation and is no longer represented by the association (Art. R 623-14). However, non-acceptance does not extinguish the individual claim: the consumer can still bring their own action against the professional. In a simplified action de groupe, this means the professional may face a wave of individual actions from non-accepting consumers after the class action concludes.
The most practically significant difference between the simplified and standard procedures is in the consumer-reaching phase. In the standard procedure, the professional must mount a public information campaign using channels ordered by the court — press, television, radio, social media, email, SMS — designed to reach an unknown population of consumers. In the simplified procedure, the professional must instead notify each consumer individually. Where the professional holds the contact details of every affected customer, individual notification may in practice be less costly than a multi-channel public campaign — but it is also more legally precise: errors in individual notification or incomplete notification of the affected population can create disputes about which consumers were properly informed.
What the Simplified Procedure Means for Defendant Businesses
The simplified action de groupe represents both a more focused risk and a potentially faster resolution than the standard procedure. For defendant businesses, the key implications are:
- The professional's financial exposure is calculable from the judgment. Because the harm amount is uniform and the consumer population is known, the first judgment effectively sets the total compensation liability at the moment it is rendered. There is no uncertainty about how many consumers will join during an adhesion window.
- The information obligation runs to each consumer individually. The professional must notify each consumer individually after the judgment becomes final. This requires accurate, current contact data for every affected customer. Failure to notify or non-compliant notification risks disputes about which consumers were properly reached.
- Non-execution produces a second judgment. The simplified procedure does not eliminate the possibility of a second round of proceedings. If the professional fails to pay consumers who have accepted, the court resolves all unsatisfied claims in a single second judgment, with enforcement costs borne by the professional (Art. L 623-21).
- The same appeal mechanism applies. The simplified action's first judgment is appealed under the same bref délai procedure. The same asymmetric res judicata applies: the judgment binds the professional from pronouncement, while consumers are only bound once compensated.
- Non-accepting consumers may sue individually. Where a proportion of consumers decides not to accept, those consumers retain their individual claims. The simplified procedure therefore does not provide the finality of a fully settled class action.
The simplified procedure's structure — known consumers, known numbers, uniform harm — also creates a clearer framework for negotiated resolution. Because the total potential liability is calculable from the outset, both the association and the professional can more easily assess the value of a mediated settlement before or during proceedings. The parties may at any stage of both the standard and simplified procedure seek mediation (Arts. L 623-22 et seq.). For a professional facing a simplified action de groupe with a large but calculable consumer population, early engagement with mediation — before the judgment — may produce a faster and lower-cost outcome than litigating through to judgment and then managing individual notification and acceptance.
