Questão jurídica principal
Whether the insurer had a legally protected interest to appeal the pension decision and the finding on the waiting period start date.
Decisão extraída
The insurer lacked a legally protected interest because the disputed start date lay before the legally relevant period for IV entitlement and before any potential binding effect on its own pension liability.
Fundamentação extraída
The appeal sought only a shift of the waiting period to an earlier date, outside the period relevant to the IV assessment. For such a date, the IV administration had no duty to investigate, and its findings were not binding on the pension institution. Without a concrete effect on its position, the insurer had no standing under Art. 89(1)(c) BGG and Art. 59 ATSG.
