Background

On September 1, 2014, the Meurthe-et-Moselle Primary Health Insurance Fund notified Mme [N] that she had received undue daily sickness benefits because she had engaged in unauthorized work between November 30, 2010, and November 22, 2013. An appellate court upheld the validity of that overpayment claim on December 1, 2020.

On June 10, 2021, Mme [N] asked the fund’s internal appeals commission to grant discretionary relief from the debt. After the commission refused, she challenged that decision before the social-security courts. The Nancy Court of Appeal rejected her claim, reasoning that her continued professional activity and the maintenance of her full salary while she received daily benefits characterized fraudulent conduct that barred relief under Article L. 256-4 of the Social Security Code.

The Court’s Holding

The Court of Cassation held that, for purposes of Article L. 256-4, a “fraudulent scheme” requires an insured person’s intention to conceal information in order to obtain benefits that were not due. The mere fact that an insured person performed paid work without medical authorization during a period of sick leave does not, by itself, establish such a scheme.

The Nancy Court of Appeal therefore relied on insufficient grounds when it treated Mme [N]’s continued work and maintained salary as proof of fraud. The Court of Cassation vacated the appellate judgment in its entirety and remanded the case to the Metz Court of Appeal. It did not grant debt relief itself; on remand, the court must determine whether fraud or a false declaration is established and, absent either, whether Mme [N]’s financial hardship at the time of the court’s decision justifies total or partial remission.

Key Takeaways

  • Unauthorized paid work during compensated sick leave does not automatically constitute a fraudulent scheme under Article L. 256-4 of the Social Security Code.
  • Fraud in this context requires an intention to conceal information for the purpose of obtaining benefits that were not due.
  • When reviewing the denial of discretionary relief, the court must assess the debtor’s financial hardship based on circumstances established by both parties as of the date of its own decision, unless the overpayment resulted from fraud or a false declaration.

Why It Matters

The ruling distinguishes conduct that creates a recoverable benefits overpayment from fraud that categorically prevents discretionary remission of that debt. A finding that benefits were improperly paid does not, without evidence of intentional concealment or a false declaration, eliminate the insured person’s opportunity to seek relief based on financial hardship.

The decision also clarifies the reviewing court’s role: it must independently consider current evidence of financial hardship rather than treating the prior confirmation of the overpayment as dispositive of eligibility for remission.
