Question juridique clé
Whether the disability assessment by invalidity insurance binds the occupational pension fund.
Solution extraite
The binding effect remained in place; the exceptional grounds to disregard the IV assessment were not met.
Motifs extraits
The lower court's reasoning was correct: the strict requirements for departing from the IV disability assessment were absent, and the insured's challenge did not show arbitrariness or manifest unsoundness in the IV findings.
