Questão jurídica principal
Whether the cantonal court erred in determining the insured person's status and invalidity degree under the mixed method.
Decisão extraída
The cantonal court's assessment of status and invalidity degree was upheld; the claimant remained entitled only to a three-quarters pension.
Fundamentação extraída
The Federal Court found the factual findings on hypothetical work allocation and residual earning capacity not manifestly incorrect. The claimant's objections were merely appellatory and did not show arbitrariness or a constitutional violation. The mixed method was applied consistently with settled case law.
