Kernrechtsfrage
Whether the allocation of quarter-plan administrative costs violates the legality principle because the statute does not sufficiently specify fee calculation.
Extrahierter Entscheid
No violation: although the statute does not detail the calculation, cost-covering and equivalence principles sufficiently constrain the fee; the costs were also foreseeable and reviewable.
Extrahierte Begründung
The court held that the challenged amount was not a flat fee but an aggregation of itemized staff work billed at standard hourly rates. Such individual positions could be reviewed for equivalence. The owners had also been informed in advance and had advanced most of the costs earlier, so the charge was foreseeable.
