Questione giuridica chiave
Whether the claimant was entitled to a three-quarter invalidity pension instead of a quarter pension
Decisione estratta
The disability assessment and income comparison were not shown to be unlawful; the 45% invalidity rate justified only a quarter pension.
Motivazione estratta
The cantonal court correctly relied on the medical reports and found the claimant capable of six hours of work per day with 20% reduced performance. The objections were largely appellatory and did not demonstrate an obvious factual error or a legal error under the Federal Supreme Court's limited review.
