Key legal question
Whether old-law preventive detention ordered under Art. 42 aStGB had to be set aside because the new-law detention requirements of Art. 64 StGB were not met.
Extracted holding
No. If no therapeutic measure under Art. 59-61 or 63 StGB is appropriate, the old-law detention must be continued under the amended transitional rule even if Art. 64 StGB would not itself justify a new detention order.
Extracted reasoning
The amended transitional provision requires review only for a possible therapeutic measure; if that fails, continuation of the old measure is mandatory. The reference to 'new law' concerns the execution regime, not a reassessment of the original legality of the detention.
