Key legal question
Whether the Federal Supreme Court could review the cantonal judgment on the costs imposed in a supervisory complaint proceeding.
Extracted holding
The matter was, in principle, amenable to a public-law appeal to the Federal Supreme Court once a cantonal judicial authority had ruled as immediate instance.
Extracted reasoning
The Court referred to its earlier judgment 8C_103/2010 and confirmed that the procedural route was open after cantonal judicial review.
