Kernrechtsfrage
Whether the cassation appeal could raise constitutional complaints about the trial record and factual findings.
Extrahierter Entscheid
Those complaints were inadmissible in cassation because they attacked fact-finding and constitutional/cantonal-law issues, not federal law.
Extrahierte Begründung
Cassation review was limited to violations of federal law; factual challenges and arbitrary fact-finding could only be raised by public-law appeal.
