Key legal question
Whether the original grant of a half disability pension could be revoked by reconsideration under Art. 53(2) ATSG as manifestly incorrect.
Extracted holding
The original pension award was not manifestly incorrect; reconsideration was therefore not available.
Extracted reasoning
The original decision relied on an expert report that, in light of the law then applicable, was defensible. The medical assessment involved value judgments on impairment and work capacity, and no obvious error beyond any reasonable doubt was shown.
