Questione giuridica chiave
Whether the cantonal court wrongly assessed the medical evidence and the appellant's work capacity.
Decisione estratta
The finding of 75% work capacity for light and medium work was not shown to be obviously incorrect or incomplete, and the medical evidence was assessed without arbitrariness.
Motivazione estratta
The court relied on the rheumatology expert report and the treating doctor's report, addressed the relevant medical opinions, and gave convincing reasons for preferring the expert assessment. The file contained no indication of a psychiatric disorder, and refusing further evidence did not violate federal law.
