Key legal question
Whether the residual earning capacity was economically usable on the balanced labour market
Extracted holding
Given the insured person's age, long self-employment, adaptation difficulties and short remaining activity period, the residual capacity was not realistically demandable in salaried work.
Extracted reasoning
The Federal Court accepted the cantonal findings on age and vocational circumstances and held that the lower court did not violate federal law by denying practical marketability.
