Question juridique clé
Whether the 2002 half disability pension award could be reconsidered under Art. 53(2) LPGA as manifestly erroneous.
Solution extraite
No. The original award was not manifestly wrong on the legal and factual situation then existing; reasonable doubts remained, and later case law changes do not justify reconsideration.
Motifs extraits
The initial decision relied on an admissible assessment of work capacity and residual earning capacity. The near identity of disability degrees in the habitual and adapted work settings, the rounding issue, and the generous but still arguable deduction did not make the award plainly erroneous.
