Question juridique clé
Whether the reimbursement claim was time-barred under Art. 25 ATSG
Solution extraite
The one-year period began when the office knew the reimbursement ground and could readily determine the amount; it did not wait for the appeal against the pension cancellation to become final.
Motifs extraits
The statute does not require final resolution of the pension cancellation before the reimbursement period starts. The office already knew the relevant facts when it issued the cancellation decision and could calculate the overpaid amount quickly.
