Questione giuridica chiave
Whether the disability pension decision of 13 November 2003 could be reopened by procedural revision based on the later-discovered employment relationship and income.
Decisione estratta
Yes. The undisclosed work relationship since 1 May 2001 was a new and important fact requiring procedural revision of the 13 November 2003 decision.
Motivazione estratta
The relevant comparison point was the last materially reasoned decision, namely the 13 November 2003 review decision. The employment facts were unknown despite diligence and were decisive enough to alter the prior factual basis.
