Kernrechtsfrage
Whether the nullity appeal could challenge the factual findings and evidence assessment.
Extrahierter Entscheid
The appellant could not attack the speed finding or the expert calculations, because the nullity appeal is limited to federal law and does not review evidence assessment or facts.
Extrahierte Begründung
The Federal Court is bound by the cantonally established facts, except for manifest inadvertence, and cannot consider new facts or evidence.
