Key legal question
Whether the cantonal court violated Art. 68(2) CP when fixing a six-month custodial sentence as a supplementary sentence.
Extracted holding
No. The cantonal court applied the rules on retrospective concurrence and supplementary sentencing correctly; the six-month sentence was not excessively severe.
Extracted reasoning
The court restated that Art. 68(2) CP requires the offender not to be punished more harshly than if all offences had been judged together. With several prior convictions, older offences must be grouped and added as supplementary components. Given the defendant's continuing and substantial drug trafficking after earlier convictions, the additional six-month sentence was within federal law.
