Key legal question
Whether the public law appeal could seek substantive release of the opposition and related cantonal costs orders.
Extracted holding
In a public law appeal, the Federal Tribunal generally may only annul the challenged decision; the requests for the Court itself to grant provisional release, dismiss the respondent's other claims, and impose cantonal costs were therefore inadmissible.
Extracted reasoning
Such relief exceeds the usual scope of the remedy, and no exception applied because the legal situation was not sufficiently clear.
