Questione giuridica chiave
Whether the pension could be revoked by revision rather than reconsidération of the original award
Decisione estratta
The pension was not revoked through reconsidération of the original decision, but through a revision justified by changed circumstances.
Motivazione estratta
The decisive comparison was between the factual situation at the original pension award and at the later decision on opposition; the intermediate 2002 decision did not alter the relevant baseline.
