Kernrechtsfrage
Whether the pension revocation was justified under the transitional rules for unclear complaints (lit. a para. 1 SchlBest. IVG).
Extrahierter Entscheid
The transitional rules apply even when the original pension also took explanatory impairments into account, as long as the unclear complaints can be separated from the explanatory ones.
Extrahierte Begründung
The court held that excluding mixed pensions would create unjustified unequal treatment. Rent review under the transitional rule focuses on the unclear complaints and their assessability under Article 7 ATSG.
