Question juridique clé
Whether the cantonal court violated evidentiary rules by failing to assess the report of Dr. I. and the conflicting medical opinions.
Solution extraite
Yes. The later report had to be considered because it concerned the same symptoms as before the decisive date and there was no indication of a new deterioration; the cantonal court failed to address the contradictions with the Institute Y. expertise.
Motifs extraits
Free evaluation of evidence requires that all relevant medical reports be weighed and reasons given for preferring one opinion over another. Ignoring a decisive report breaches federal law.
