Cour de cassation (French Supreme Court)

The Cour de cassation dismissed the bank’s grounds of appeal against the ruling of the Lyon Court of Appeal of September 3, 2024, which had annulled the Swiss franc loans: that annulment stands. On a ground raised of its own motion, the Court quashed, without remand, only the part of the ruling concerning insurance premiums: the bank, which merely took out the group insurance policy, is not required to refund premiums paid to the insurer, since they were not owed to it.
Case handled by DANA Avocats, which instructed a member of the Bar of the Conseil d’État and the Cour de cassation (avocat aux Conseils) to argue it before the Court.
