Questão jurídica principal
Whether the appellant was the correct BVG obligor after the employer changed pension affiliation in 1999.
Decisão extraída
The appellant remained passively legitimized; the insured person stayed with the former pension arrangement because the decisive disability event occurred before the affiliation ended.
Fundamentação extraída
The relevant regulations did not provide for transfer of pending disability cases on affiliation termination; under the fund rules, persons whose insured event arose before termination remained covered by the former institution.
