Kernrechtsfrage
Whether the retroactive payment of the corrected disability pension had to run back to the original pension start in 2009.
Extrahierter Entscheid
No. The claim to unpaid benefits for the period before May 2013 had lapsed under the five-year forfeiture period.
Extrahierte Begründung
Art. 24 ATSG applies to periodic benefits such as pensions. The absolute five-year period runs from the end of the month for which the benefit was owed and also applies when the administration corrects an earlier clearly wrong award and pays a higher benefit retroactively.
