Kernrechtsfrage
Whether the cantonal court violated the accusation principle and the defense rights by upholding a conviction based on a more specific version of the braking maneuver than the renvoi order expressly stated.
Extrahierter Entscheid
No violation: the renvoi, read with the file and the cited legal qualifications, sufficiently informed the accused that he was answering for an inopportune slowdown after overtaking, so he could prepare his defense.
Extrahierte Begründung
The court held that cantonal law and the constitutional/ECHR guarantees are satisfied when the accused can reasonably anticipate the factual and legal basis of the charge; the defendant was assisted by counsel and had been confronted with the witness evidence before the renvoi order.
