Key legal question
Whether the municipality had standing under Art. 89(1) BGG to challenge the costs order
Extracted holding
No. The municipality's purely financial interest in avoiding the CHF 1,000 fee was not a sufficiently qualified interest; it was not affected like a private party.
Extracted reasoning
Municipalities may invoke Art. 89(1) BGG only restrictively and only when they are specially and qualifiedly affected. The costs arose from the municipality's own administrative enforcement activity, so the burden did not create standing.
