Key legal question
Whether the cantonal court unlawfully applied a 15% deduction to the statistical wage when assessing invalidity income.
Extracted holding
The 15% deduction was not unlawful; the cantonal court acted within its discretion and did not violate federal law.
Extracted reasoning
Use of ESS TA1 was permissible. The deduction took account of the insured person's handicap, including exclusion from heavy work, reduced performance, and limited cognitive abilities, but not age. The Federal Supreme Court found no improper exercise of discretion or manifest legal error.
