Questione giuridica chiave

Decisione estratta
The cantonal court departed from the expert report without sufficient reasons; this violated federal law.
Motivazione estratta
A court may deviate from a psychiatric opinion only for compelling reasons. Here, uncertainty about the exact extent of cannabis and alcohol habituation did not justify rejecting the expert's finding of full capacity.
