Questione giuridica chiave
Whether the cantonal court arbitrarily assessed the evidence and violated the presumption of innocence / in dubio pro reo.
Decisione estratta
No. The cantonal assessment was not arbitrary and the presumption-of-innocence complaint failed because the conviction rested on several converging pieces of evidence.
Motivazione estratta
The federal court held that the complaint partly raised issues of federal law and was partly inadmissible in public-law proceedings, and that the cantonal court could rely on the blood analysis, breathalyzer results, police observations, and the defendant's own statements.
