Kernrechtsfrage
Whether the federal appeal could challenge the lower-instance decisions despite limited cantonal review and incomplete exhaustion of remedies
Extrahierter Entscheid
Only the cantonal appellate and cassation decisions were open to federal review; arguments that could have been raised in cantonal nullity proceedings were inadmissible.
Extrahierte Begründung
Art. 75 BGG requires exhaustion of the cantonal instance chain for the specific complaints raised, and the appellant's brief did not properly address the cassation court's reasoning.
