Key legal question
Whether the pension fund was entitled to appeal against the disability pension award and whether the insured person was the proper opposing party
Extracted holding
The pension fund had standing because it is bound by the IV disability assessment; the insured person was the opposing party, not merely a joined third party.
Extracted reasoning
Under Art. 49(4) ATSG and Art. 89(1) BGG, the pension fund may challenge a pension award to an insured person. In this constellation the insured person's pension claim is the subject of the dispute, so he must be treated as respondent.
