Kernrechtsfrage
Whether the restitution claim for overpaid supplementary benefits was time-barred under Art. 25 para. 2 LPGA
Extrahierter Entscheid
The one-year period began when the fund actually learned of the undisclosed earned income during the October 2005 review, so the November 2005 restitution decisions were timely.
Extrahierte Begründung
The period runs from knowledge of the relevant facts by the authority competent to decide restitution, or from the time it should have discovered them with reasonable diligence. Knowledge by a local AVS agent without restitution competence would not start the period; in any event the fund only became aware of the decisive new fact in October 2005.
