Questão jurídica principal
Whether the cantonal court unlawfully increased the wage deduction applied to the statistical invalid income.
Decisão extraída
The higher deduction was not shown to violate federal law or exceed the court's discretion.
Fundamentação extraída
The Federal Court held that review of the existence of a deduction is full, but the concrete extent is discretionary and only reviewable for abuse. Age close to advanced age could be considered, and long inactivity was only part of the overall assessment.
