Kernrechtsfrage
Whether the cantonal supervisory authority could rely on the expert valuation despite objections about omitted insurance proceeds and project participants.
Extrahierter Entscheid
The complaint was insufficiently substantiated; the challenged valuation was not shown to be arbitrary or unlawful.
Extrahierte Begründung
Under the backward-calculation method used by the expert, insurance compensation for an already occurred loss was not a deduction from construction costs, unlike a subsidy that lowers building costs. The appellant also failed to show that the expert omitted relevant valuation bases regarding the permissible and probable development.
