Questão jurídica principal
Whether the IV findings on the onset of invalidating incapacity were binding on the occupational pension foundation.
Decisão extraída
The IV findings were not manifestly untenable and were therefore binding on the foundation.
Fundamentação extraída
The IV authorities had involved the foundation and their decisions were final; the file as it stood when the IV decisions were issued did not make the IV assessment obviously unsustainable. Later medical evidence could not undermine that assessment.
