Questione giuridica chiave
Whether the pension revision of 5 July 2007 was based on a genuine change in circumstances or merely a new assessment of an unchanged condition.
Decisione estratta
The revision was unsupported because the medical situation had remained essentially unchanged; it was only a new appraisal of the same facts.
Motivazione estratta
The specialist's June 2006 assessment repeated the June 2005 assessment, showing a stationary state of health. Revision under Art. 17 LPGA requires a significant factual change, not merely a different valuation.
