Question juridique clé
Whether the cantonal court violated federal law by refusing to remand for additional medical examinations.
Solution extraite
No. The existing file did not show relevant contradictions or any indication that the health status had changed; anticipatory assessment was not arbitrary.
Motifs extraits
The duty to investigate is breached only if the facts are incomplete or contradictory on a decisive point. A two-year gap alone does not require a new examination when no change in condition is shown.
