Questão jurídica principal
Whether the cantonal court violated the presumption of innocence and in dubio pro reo when assessing the evidence.
Decisão extraída
No. The appellant's objections were merely appellatory and did not show arbitrariness; the cantonal court's evidence assessment stood.
Fundamentação extraída
The Supreme Court held that challenges to witness credibility and the reconstruction of the accident did not demonstrate arbitrariness. The lower court's findings were supported by consistent testimony and a plausible time-distance calculation; even possible speeding by the motorcyclist would not exculpate the appellant because Swiss criminal law does not recognize guilt compensation.
