Kernrechtsfrage
Whether the public law appeal was admissible despite the appellants raising arbitrariness arguments for the first time at federal level.
Extrahierter Entscheid
The appeal was inadmissible because the arbitrariness complaint was new and the relevant nullity remedy had not been properly argued before the cantonal court.
Extrahierte Begründung
Under the exhaustion principle, only grievances raised, where possible, before the last cantonal instance are admissible. The appellants had filed a nullity appeal in Vaud but did not develop a nullity ground there.
