Questão jurídica principal
Whether the cantonal court could depart from the psychiatric expertise and impose an institutional therapeutic measure instead of ambulatory treatment.
Decisão extraída
The court could not depart from the expertise without serious, specific reasons; doing so here was arbitrary.
Fundamentação extraída
The expert report contained no contradiction and already addressed the prior relapses and the failure of earlier ambulatory treatment. The cantonal court merely substituted its own assessment for the expert's without sufficient basis.
