Kernrechtsfrage
Whether a pension fund has standing to appeal an AI decision that fixes only the pension start date where the disputed incapacity date is not decisive for the AI pension entitlement.
Extrahierter Entscheid
The fund lacked a legally protected interest because the challenged incapacity date, although mentioned in the reasoning, did not determine the AI pension start date and was not binding on the occupational pension scheme.
Extrahierte Begründung
AI decisions bind occupational pension institutions only as to findings decisive for the AI pension entitlement. Since the AI pension arose solely under Art. 29 al. 1 LAI, the earlier incapacity date had no binding effect on the fund.
