Kernrechtsfrage
Whether the cantonal court's finding of a minor speeding violation was arbitrary and violated the presumption of innocence.
Extrahierter Entscheid
The evidence assessment was not arbitrary; the conviction could be based on the police officers' observations and the complainant's own statement, despite flaws in the speed-measurement device.
Extrahierte Begründung
The Federal Court held that only serious, unavoidable doubts matter under in dubio pro reo. The complainant's objections created at most theoretical doubts. The cantonal court could reasonably infer a slight speeding offense from the overall circumstances.
