Kernrechtsfrage
Whether the disability pension could be revoked under Art. 17 ATSG or the transitional provisions of the 6th IV revision.
Extrahierter Entscheid
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.
Extrahierte Begründung
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.
