Key legal question
Whether the claimant had an invalidity-degree entitling him to an AI pension.
Extracted holding
No pension entitlement was established because he retained full capacity for light adapted work.
Extracted reasoning
The medical file consistently showed longstanding spinal complaints with identical functional limits, but the psychiatric evidence and several expert reports did not support a disabling mental disorder; the claimant could perform light work with position changes and without heavy lifting or repetitive movements.
