Key legal question
Whether the public-law appeal showed arbitrariness or violation of the presumption of innocence in the factual findings.
Extracted holding
The constitutional complaints were either insufficiently reasoned or unfounded; the cantonal court did not act arbitrarily and did not shift the burden of proof.
Extracted reasoning
The Federal Court held that many arguments were merely appellatory. On the merits, the lower courts could reject alternative explanations such as mechanical defect or shock-induced unconsciousness because they were unsupported and introduced too late.
