Kernrechtsfrage
Whether the cantonal court violated the principle of free assessment of evidence by ignoring key medical reports and the work placement observation.
Extrahierter Entscheid
Yes. The cantonal court had to examine all available medical evidence and explain why it preferred one opinion over others; it could not rely on a purely formal appraisal.
Extrahierte Begründung
The appeal court must establish relevant facts ex officio under the inquisitorial principle. Because the file contained divergent medical opinions, hospital expertises, and an occupational observation, the cantonal court had to deal with them materially and state why they were rejected or preferred.
