Questão jurídica principal
Whether the cantonal court arbitrarily ignored a quantified loss of productivity in assessing residual work capacity.
Decisão extraída
No. The experts only described a hypothetical, occasional risk of diminished performance; they expressly answered that productivity was not reduced in the adapted work capacity of 50%.
Fundamentação extraída
The Federal Supreme Court held that the cantonal court reasonably interpreted the medical report: the experts assessed a 50% work capacity without a concrete, quantifiable productivity reduction. Their remarks about possible intermittent worsening merely described a risk, which could be disregarded when determining residual capacity.
