Kernrechtsfrage
Whether the original 2002 half-pension decision was manifestly erroneous and could be reconsidered under Art. 53(2) LPGA.
Extrahierter Entscheid
No. In light of the medical evidence available at the time, the original pension award was not clearly and manifestly wrong.
Extrahierte Begründung
The court considered the contemporaneous medical reports, including the treating physician's assessments, and held that the initial file did not justify treating the 50% invalidity assessment as obviously mistaken. Reasonable doubts remained, which excludes reconsideration.
