Background
M. [X] was injured in a traffic accident involving a vehicle insured by Mutuelle assurance travailleur mutualiste (MATMUT). He sued the insurer for compensation, with the Calvados primary health insurance fund and Mutuelle bleue, later succeeded by Viasanté mutuelle, joined in the proceedings.
The Caen Court of Appeal ruled that the compensation payable to M. [X] would bear interest at twice the statutory rate from January 1, 2008, until the judgment became final. It also ordered capitalization of doubled-rate interest that had accrued for more than one year, effective from October 2, 2019, the date on which capitalization was judicially requested. Both M. [X] and MATMUT appealed to the Court of Cassation, challenging that starting point from opposite directions.
The Court’s Holding
The Court of Cassation rejected both appeals. It held that the Insurance Code provisions imposing interest at twice the statutory rate when an insurer fails to make a timely compensation offer do not displace Civil Code article 1343-2. That article, which applies generally to default interest, permits accrued interest owed for at least a full year to produce further interest when a contract so provides or a court orders it.
When capitalization is requested in court, it is available as of right and must be set from the date of the first judicial request, but only for interest that has already accrued for more than one year. The Court of Appeal therefore correctly selected October 2, 2019—the date of M. [X]’s request—rather than January 1, 2009, as M. [X] argued, or one year after the request, as MATMUT argued. The Court also summarily rejected the parties’ remaining grounds because they were manifestly incapable of supporting reversal.
Key Takeaways
- Interest imposed at twice the statutory rate under the Insurance Code remains subject to the Civil Code rules governing capitalization of default interest.
- Judicially requested capitalization begins on the date of the first request, provided the underlying interest has already accrued for at least one full year.
- A claimant need not wait an additional year after requesting capitalization when at least one year of interest has already accrued.
Why It Matters
The decision clarifies how France’s general rule on compound interest interacts with the penalty interest imposed on motor insurers for untimely compensation offers. It confirms that the enhanced rate does not alter the procedural and temporal requirements for capitalization.
For practitioners calculating traffic-accident awards, the critical date is the first judicial request for capitalization, while eligibility depends on whether at least a full year of interest has accrued. Promptly requesting capitalization can therefore materially affect the ultimate recovery.
