Kernrechtsfrage
Whether the 2002 disability pension decision could be reconsidered under Art. 53(2) LPGA due to manifest error in the invalidity assessment.
Extrahierter Entscheid
The original decision was not manifestly erroneous in the decisive respects and could not be reconsidered.
Extrahierte Begründung
A reconsideration requires a clear, undeniable error, not merely a different later assessment. The 25% deduction from the invalid income was within the administration's discretion and was not shown to be inadmissible or plainly unsustainable on the facts and law then existing.
