Kernrechtsfrage
Which pension plan governs the calculation of the disability pension
Extrahierter Entscheid
The applicable plan is the one in force when the pension entitlement arose, not the plan in force when incapacity began.
Extrahierte Begründung
No transitional provision departed from the general rule. Under the plan, disability pension and contribution exemption were subject to separate waiting periods; the pension entitlement arose after one year of incapacity, while payment was deferred to the end of the longer waiting period.
