Questão jurídica principal
Whether the 1993 AI rent award could be withdrawn by reconsideration under Art. 53 para. 2 LPGA.
Decisão extraída
The prior rent award was not manifestly erroneous, so reconsideration was not permissible.
Fundamentação extraída
The 1993 decision was based on a supportable medical assessment at the time; a later contrary COMAI expertise does not by itself prove the original decision was manifestly wrong.
