Kernrechtsfrage
Whether the valid income for an insured person who could not acquire adequate vocational skills because of disability must be based on the BSV-fixed values under Art. 26(1) IVV or adjusted using LSE/working-time calculations.
Extrahierter Entscheid
For such early-invalid cases, equal treatment requires reliance on the values fixed by the Federal Social Insurance Office; no further adjustment using LSE tables or weekly working-time averages is required.
Extrahierte Begründung
Art. 26(1) IVV expressly refers to the annually updated median value published by the BSV. The court relied on prior Federal Insurance Court case law and held that the BSV-fixed annual amount is the proper benchmark. The claimant's proposed recalculation had no statutory basis and would not improve equal treatment.
