Question juridique clé
Whether the revision and revocation of the quarter invalidity pension were lawful under changed health circumstances.
Solution extraite
The pension was lawfully revoked because the insured person's health had materially improved and he was again fully capable of adapted work, leaving only a 10% residual disability.
Motifs extraits
The Federal Supreme Court upheld the lower court's reliance on the psychiatric expert report. Divergent treating-physician opinions did not create serious doubts about the report's completeness or conclusiveness. A dysthymic or phobic diagnosis was not sufficient, on the record, to establish invalidating incapacity.
