Questão jurídica principal
Whether the pension fund was entitled to challenge the IV decision and how far its standing extended.
Decisão extraída
The pension fund was entitled to appeal because it had been duly notified; however, its challenge was limited to questions decisive for the pension claim, not to periods before the legally relevant waiting year.
Fundamentação extraída
Under Art. 49(4) ATSG and the IV notification rules, a pension fund is bound only on issues relevant to the IV pension determination if it was properly included in the proceedings. The period before August 2011 was irrelevant to the IV waiting year because the insured applied on 2012-02-20 and pension entitlement could arise only from 2012-08-01 at the earliest.
