Questione giuridica chiave
Whether the reimbursement claim for overpaid supplementary benefits was time-barred under Art. 25 Abs. 2 ATSG.
Decisione estratta
The claim was not time-barred because the one-year relative limitation period began at the latest with the periodic review in September 2012 and was preserved by the reimbursement decision of 14 November 2012.
Motivazione estratta
The office could not be expected to detect the initial calculation errors earlier on the available record. For periodic reviews under Art. 30 ELV, any unlawfulness becomes detectable at the latest when the economic circumstances are reviewed; the claimant had not disclosed the spouse's vested-benefit account earlier.
