Kernrechtsfrage
Whether the federal appeal against the cantonal judgment was admissible as an immediately challengeable interim decision.
Extrahierter Entscheid
The cantonal judgment was an interim decision that could be challenged immediately because it would otherwise cause irreparable legal disadvantage to the municipality.
Extrahierte Begründung
The judgment did not end the contribution procedure but fixed the cost basis for later allocation; the municipality would otherwise have to issue subsequent decisions on an unfavorable basis without effective later correction.
