23. Proceedings for the payment of family benefits are prescribed after three years. However, the prescription does not run in respect of a payment resulting from a new computation of the income taken into account in determining the amount of the family allowance.
Proceedings instituted by the Board for the recovery of unduly paid benefits are prescribed after three years. In the case of bad faith on the part of the person who received the benefits, proceedings are prescribed three years after the date on which the Board became aware of the fact that the sum was payable. However, in such a case, no proceeding may be instituted if 15 years have elapsed since the date on which the benefits were paid.
