Questão jurídica principal
Whether the cantonal court committed an arbitrary factual assessment by relying on the RAD medical files instead of ordering a comprehensive expert report
Decisão extraída
The factual findings were not shown to be manifestly incorrect, and the medical file assessment was sufficiently probative.
Fundamentação extraída
The appellant offered only appellatory criticism. The RAD physician had access to the back-related records, and the orthopedic specialist later confirmed the assessment. The contrasting rheumatology opinion did not make the cantonal court's weighing of evidence arbitrary.
