Key legal question
Whether the sentencing and addition of a partial supplementary sentence under Art. 68 StGB were unlawful.
Extracted holding
The method used by the cantonal court was not ideal, but it did not prejudice the appellant overall.
Extracted reasoning
Although the court should first have fixed a hypothetical sentence for post-judgment offenses and then a hypothetical total sentence for pre-judgment offenses, its chosen overall calculation did not worsen the appellant's position.
