Questione giuridica chiave
Whether the 1995 grant of a full invalidity pension was manifestly incorrect and could be revoked by reconsideration/revision.
Decisione estratta
The original pension award was not obviously wrong on the basis of the records then available, so substitution of reasons for revocation was not permissible.
Motivazione estratta
The earlier medical file supported a near-total incapacity; the absence of a formal income comparison was only an indication of error, not sufficient by itself. The later 2008 assessment could not be used to judge the former state of health.
