Key legal question
Admissibility of the public law appeal against the cantonal ruling
Extracted holding
The appeal was admissible only insofar as it complied with the strict requirements of a cassatory public law appeal; requests for declaratory findings were inadmissible.
Extracted reasoning
The Court examined admissibility ex officio, found exhaustion of cantonal remedies and standing, but held that the remedy is in principle purely cassatory and requires specific constitutional reasoning.
