Key legal question
Whether the cantonal court arbitrarily imputed income by adding withheld-source taxes to the appellant's earning capacity.
Extracted holding
Yes. For criminal liability under Art. 217 CP, only resources actually available or realistically obtainable matter; withheld taxes were not available to the appellant and could not be counted.
Extracted reasoning
The criminal court must independently assess the debtor's concrete financial capacity. Civil maintenance decisions may be consulted, but their method cannot replace the penal assessment. Including sums withheld at source was unsustainable and arbitrary in result.
