Key legal question
Whether the respondent remained entitled to a full occupational invalidity pension under the pension fund rules despite an 81% disability rating.
Extracted holding
Yes. Under the applicable regulations and BVG-compliant interpretation, a full pension remained payable because the insured salary had fully fallen away.
Extracted reasoning
Section 19 VB regulates partial invalidity based on a reduced insured salary; where the insured salary disappears entirely and no new insured employment continues, the rule does not justify limiting the pension to 81%. The same interpretation applies in the mandatory and extra-mandatory areas of an umbrella fund, and the reglementary scheme is not incomplete.
