Key legal question
Whether the 10% deduction from the statistical wage in the disability income calculation violated federal law.
Extracted holding
The 10% deduction was lawful; the cantonal court did not abuse its discretion.
Extracted reasoning
Advanced age, long service, structural labour-market conditions and inability to do heavy work did not justify a higher deduction; the claimant's profile as an experienced construction specialist meant market integration was not materially hindered.
