Kernrechtsfrage
Whether the appellant could demand continued occupational disability pension payments until age 64 under the supplementary plan
Extrahierter Entscheid
No. The transitional clause tied the old-age retirement age to the rules in force when incapacity for work began, so the disability pension ended at 62.
Extrahierte Begründung
In supplementary pension insurance, the foundation had contractual autonomy to define benefits and financing. Applying the older regulation did not violate equality or arbitrariness because extending disability benefits post hoc would create unfunded new obligations.
