Kernrechtsfrage
Whether a provisional connection-fee decision remains open to challenge as to all elements or only as to the still undetermined variable.
Extrahierter Entscheid
In a provisional fee decision, only the parameters that cannot yet be definitively determined remain open to appeal; all other elements are finally fixed and become res judicata.
Extrahierte Begründung
Because the brand-insurance value was not yet known before completion of construction and the AVA assessment, the authority could only reserve the final amount. However, the calculation method, fee rates, and scope of the buildings were definitively determined and thus no longer challengeable.
