Questione giuridica chiave
Whether the cantonal prosecution was entitled to file a criminal appeal and raise constitutional and factual challenges before the Federal Supreme Court.
Decisione estratta
The prosecution had standing under Art. 81 BGG and could invoke arbitrariness and factual errors because the appeal in criminal matters is an ordinary remedy open to the prosecution as representative of the state punishment claim.
Motivazione estratta
The court held that participation before the lower instance was satisfied through the subordinate authority that conducted the appeal proceedings, while the cantonal prosecutor remained able to influence the case through supervisory and instruction powers. Under the unified appeal system, the prosecution may raise all legal violations, including constitutional ones and challenges to fact-finding.
