Question juridique clé
Whether the revision and suppression of the AI pension under Art. 17 LPGA were justified by a relevant change in condition.
Solution extraite
Yes. The medical evidence showed a notable improvement in the claimant's psychiatric condition and a resulting loss of pension entitlement.
Motifs extraits
The Federal Court held that the cantonal court could rely on the administrative expertise; the expert findings were not shown to be manifestly inaccurate. The change was not merely a new appraisal of an unchanged condition, but reflected an actual improvement over time.
