Question juridique clé
Whether the IV pension could be terminated by reconsideration or revision
Solution extraite
The original pension award was manifestly incorrect and could be corrected by reconsideration; the termination decision was upheld.
Motifs extraits
The initial pension grant lacked a convincing medical basis and violated the duty to investigate. Because the error was obvious and material, reconsideration was permissible even if the formal revision requirements were not conclusively examined.
