Key legal question
Whether the 2002 award of a full disability pension could be revised/reopened under Art. 53 ATSG and reduced to a quarter pension from 1 November 2005.
Extracted holding
The original pension award was not clearly incorrect, so reopening under Art. 53(2) ATSG was not available.
Extracted reasoning
For reopening, the prior decision must be unmistakably wrong in light of the facts and law as they stood then. The medical record in 2002 made the full pension at least defensible; there was no single compelled conclusion that the award was erroneous.
