Key legal question
Whether the federal complaint could challenge matters already reviewable by the cantonal cassation court.
Extracted holding
Most factual and procedural complaints were inadmissible because they were not directed against the cantonal cassation decision or concerned issues that could have been reviewed there.
Extracted reasoning
Only cantonally final issues may be attacked federally; arguments on arbitrariness, hearing violations, bias, and record incompleteness had to be exhausted before the cassation court and were not properly carried over against its decision.
