Questão jurídica principal
Whether the cantonal court arbitrarily assessed the evidence and established diminished responsibility at only a slight level.
Decisão extraída
No. The psychiatric assessment was expressed as an approximation, and the accepted alcohol level left interpretive room; the result was not arbitrary.
Fundamentação extraída
Arbitrariness requires an insupportable result, not merely disputable reasoning. The expert’s range of 30–40% left the court discretion, and the court relied on a lower alcohol estimate than the expert's highest assumption.
