Questão jurídica principal
Whether the 2003 pension decision could be reconsidered under Art. 53(2) LPGA as manifestly incorrect.
Decisão extraída
No. The original decision was not manifestly erroneous, because the file and the medical assessment available at the time did not make the award obviously wrong.
Fundamentação extraída
The absence of a psychiatric expertise did not, by itself, make the 2003 decision legally erroneous under the jurisprudence then in force. The AI office relied on several medical opinions supporting a 50% incapacity, so the evidentiary basis was not evidently incomplete and any error remained at most debatable.
