Key legal question
Whether the initial award of a full invalidity pension could be reconsidered as manifestly erroneous under Art. 53(2) LPGA
Extracted holding
Yes. The original decision ignored the post-operation medical situation and the resulting residual work capacity, so the grant of a full pension was manifestly erroneous.
Extracted reasoning
The administration failed to reassess the insured after surgery and overlooked medical opinions and COPAI findings indicating a residual capacity with reduced performance. This made only the full pension, not the existence of any pension entitlement, manifestly wrong.
