Key legal question
Whether the criminal appeal was admissible despite only challenging one of two independent reasons for acquittal.
Extracted holding
The appeal was inadmissible because the appellant failed to contest all independent and sufficient grounds supporting the cantonal judgment.
Extracted reasoning
Where a decision rests on multiple independent, alternative or subsidiary grounds, each sufficient on its own, the appellant must show that each ground violates federal law. The appellant only attacked the handling of the complaint and did not challenge the finding that the subjective element of trespass was lacking.
