Key legal question
Whether the disability pension could be revoked under Art. 17 ATSG or the transitional provisions of the 6th IV revision.
Extracted holding
The revocation could not be upheld: neither a revision under Art. 17 ATSG nor reopening/reconsideration conditions were met, and the 6th IV revision transitional rule did not apply.
Extracted reasoning
The original 2004 pension award was not based solely on a pathogenetically/etiologically unclear syndrome without organic basis. The record showed multiple somatic conditions with objective organic findings, so the statutory special review ground was absent.
