Key legal question
Whether 'net income' under the alimony advance-payment regulation must be determined by reference to the tax assessment.
Extracted holding
Yes. In the absence of a statutory definition, the tax-law assessed net income may be used as the benchmark for determining net income under the regulation.
Extracted reasoning
The cantonal tax system also aims to capture real economic capacity and uses a careful assessment procedure. That procedure is at least as reliable as any welfare assessment, especially for self-employed persons. Departing from the tax result for some categories would create inconsistency and unequal treatment.
