Key legal question
How to determine the insured person's pre-injury income for calculating the invalidity pension
Extracted holding
The cantonal court correctly relied on the actual salary earned during the tunnel work period and annualized it; no basis existed to use the higher salary estimates invoked by the insured.
Extracted reasoning
The employer's wage breakdown reflected the remuneration actually earned, including relevant supplements. A later industry estimate was not comparable and would imply an unproven real wage increase.
