Questão jurídica principal
Whether the claimant could obtain pension arrears for a period earlier than twelve months before the application date
Decisão extraída
Retroactive payment is limited to the twelve months preceding the application; earlier arrears cannot be awarded.
Fundamentação extraída
No earlier pension application than 15 March 2004 was documented. Under Art. 48 Abs. 2 IVG, benefits may be paid retroactively only for the twelve months before the claim, so the pension start date remains 1 March 2003.
