Kernrechtsfrage
Whether the BVK correctly calculated the appellant's old-age pension under the cantonal pension statutes and BVG principles.
Extrahierter Entscheid
The calculation was not shown to violate federal law; the pension amount determined by the BVK was upheld.
Extrahierte Begründung
The court held that the cantonal pension scheme lawfully operated on a defined-contribution basis and that the appellant failed to demonstrate unequal or arbitrary treatment. Her own figures already showed that the combined AHV and pension benefits exceeded 60% of her last salary.
