Key legal question
Whether new medical reports and alleged misdiagnosis justified revision of the final 27 January 2009 denial under Art. 53(1) ATSG
Extracted holding
No revision ground was shown because the later reports did not establish a substantial new fact existing before the original decision and undiscoverable with due diligence.
Extracted reasoning
Revision requires a pre-existing, materially significant new fact or evidence. Later medical opinions that merely revisit diagnosis or assess work capacity differently do not suffice where they depend on medical judgment and do not reveal a grave, untenable error in the earlier procedure.
