Questão jurídica principal
Whether the cantonal court had to order a further psychiatric expert opinion before deciding the AI dispute.
Decisão extraída
No. The existing medical file, especially the SMR report, was sufficient and no pertinent medical opinion required further investigation as of the decisive date.
Fundamentação extraída
The mere lapse of time did not automatically reduce probative value. The later psychiatric reports did not convincingly contradict the SMR findings on the relevant date, and the private specialists did not assess objectively exigible work capacity.
