Key legal question
Whether the federal nullity complaint could challenge the lower court's findings of fact and proof assessment under the principle of in dubio pro reo.
Extracted holding
No; the complaint could only allege federal-law violations, not challenge factual findings or evidence appraisal.
Extracted reasoning
The complaint is purely cassatory and the Federal Court is bound by the cantonal findings of fact; arguments about proof sufficiency and in dubio pro reo concern procedural guarantees or facts and are not cognizable in this remedy.
