Key legal question
Whether the municipality had standing to file a constitutional complaint against the cantonal cost allocation.
Extracted holding
The municipality was acting as a public authority in the permitting dispute and did not invoke any autonomy guarantee; it therefore had no standing.
Extracted reasoning
Public-law bodies may appeal only exceptionally, notably when their autonomy or legal personality is affected or when they act like private persons. Here the municipality participated as permitting authority, so the challenged cost order affected it in its sovereign capacity.
