Key legal question
Whether the four-year extension of the stationary therapeutic measure was permissible under Art. 59(4) StGB.
Extracted holding
Yes. The extension was necessary and proportionate in light of the continuing treatment need and residual reoffending risk.
Extracted reasoning
Therapy reports and the prior expert opinion showed no essential change warranting a different prognosis. Progress was slow and further controlled loosening of custody was still needed to test abstinence and responsibility taking.
