Kernrechtsfrage
Whether constitutional and Convention-based complaints not raised in the cantonal nullity appeal were admissible before the Federal Tribunal.
Extrahierter Entscheid
They were inadmissible because they had not been validly raised before the last cantonal instance and the cantonal court did not have free review ex officio.
Extrahierte Begründung
Public-law appeal requires exhaustion of cantonal remedies; where the cantonal court only examines the grounds raised, new procedural grievances and similar complaints cannot be introduced for the first time before the Federal Tribunal.
