Key legal question
Whether the pension fund is bound by the IV authority's findings on the onset of incapacity and disability.
Extracted holding
The IV findings were binding in the BVG dispute because the fund had relied on the IV decision; the onset date set by the IV authority was nevertheless obviously wrong and had to be corrected on review.
Extracted reasoning
An excluded pension fund is generally not bound if it was not involved in the IV proceedings. But where it relies on the IV ruling, the insured may invoke its binding effect unless the IV decision is manifestly incorrect. Here the documentary record showed incapacity already in spring 2000, during the employment relationship, not only in December 2001.
