Question juridique clé
Whether a revision of the invalidity pension was justified due to a substantial change in disability.
Solution extraite
Yes. The psychiatric limitations had disappeared, the somatic situation was unchanged, and the remaining invalidity corresponded to 48.4%, entitling the insured only to a quarter pension from 2005-05-01.
Motifs extraits
Revision under Art. 17 LPGA requires a notable change in invalidity. The new medical reports did not show a worse somatic condition; they only disagreed with the earlier assessment. With the disappearance of the psychiatric incapacity, the reduced earning loss justified replacing the full pension.
