1699. Restitution of prestations takes place where a person is bound by law to return to another person the property he has received, either without right or in error, or under a juridical act which is subsequently annulled with retroactive effect or whose obligations become impossible to perform by reason of superior force.
The court may, exceptionally, refuse restitution where it would have the effect of according an undue advantage to one party, whether the debtor or the creditor, unless it considers it sufficient, in that case, to modify the scope or modalities of the restitution instead.
