Motifs extraits
The Federal Court upheld the cantonal court's assessment that the Institute X. expertise had full probative value. The later treating-physician statements did not raise concrete doubts, and the asserted PTSD was not sufficiently supported to require new psychotraumatological examinations. The alleged trauma occurred years before depressive symptoms, which undermined the PTSD theory under the ICD-10 latency requirements.
