Questione giuridica chiave
Whether the IV disability decision bound the pension fund despite lack of formal service
Decisione estratta
No binding effect arose because the IV decision was not formally served on the pension fund under Article 49(4) ATSG.
Motivazione estratta
Service by the insured's lawyer did not replace formal service by the IV office and did not trigger appeal deadlines; the fund therefore had no duty to file a precautionary objection and could freely review the entitlement conditions.
