Question juridique clé
Whether the 1997 disability pension decision could be reopened by reconsideration under Art. 53 para. 2 LPGA.
Solution extraite
The original pension decision was not manifestly erroneous on the record and at the legal situation prevailing in 1997; reconsideration was therefore impermissible.
Motifs extraits
The original file contained sufficient medical evidence, notably the treating physician's report, to assess work capacity and the need for rehabilitation. The later, more thorough expert appraisal amounted only to a new evaluation of the case, which cannot establish manifest error.
