Questione giuridica chiave
Whether internment could be ordered under the transitional rules and the principle of lex mitior.
Decisione estratta
The court held that the old law was more favorable in this case and that the canton court correctly refused internment under former Art. 43 ch. 1 al. 2 aCP.
Motivazione estratta
Old and new measures law cannot be mixed; retroactive application of Art. 64 CP is allowed only if more favorable. The expert report did not establish a grave mental disorder causally linked to the offenses, so the conditions for internment under the old law were not met. Under the new law, the dangerousness could be addressed by therapy rather than internment.
