Questão jurídica principal
Whether the valid income had to include family allowances and be indexed to 2005.
Decisão extraída
Family allowances could not be included in the hypothetical valid income, but the indexing had to use the 2005 nominal wage index, yielding a valid income of CHF 73,108.40.
Fundamentação extraída
Only earnings from gainful employment count for invalidity assessment; social benefits are excluded. The lower court used the wrong index year.
