Question juridique clé
Whether the lower court violated the inquisitorial principle by not ordering a new multidisciplinary medical expertise.
Solution extraite
The existing medical file, especially the multidisciplinary expert report, was sufficient to assess work capacity; no further expertise was required.
Motifs extraits
The Federal Supreme Court held that the prior expert report assessed the claimant's overall health and work capacity, while the internal medical opinions were acceptable syntheses of the file. The later reports did not raise new clinical or diagnostic elements capable of undermining those findings, so anticipated evidentiary assessment justified refusing additional evidence.
