Questione giuridica chiave
Whether the complaint could challenge the earlier final revocation of the pension or the first-instance AI decision directly.
Decisione estratta
Those grievances were inadmissible because the revocation had already been confirmed by an unappealed final judicial decision, and direct complaints against the AI office decision are not open before the Federal Tribunal.
Motivazione estratta
Only cantonal last-instance decisions can be appealed; issues covered by res judicata cannot be reopened in this appeal.
