Question juridique clé
Whether the appellate court had to hear additional witnesses on alleged alcohol consumption and diminished responsibility.
Solution extraite
The request was inadmissible: the complaint did not adequately challenge the anticipatory assessment of evidence or show arbitrariness, and the asserted alcohol intake did not make diminished responsibility plausible on the record.
Motifs extraits
The Federal Supreme Court held that the appellant failed to engage with the appellate court's reasons and did not meet the strict motivation requirements for fact-related and constitutional complaints.
