Questione giuridica chiave
Whether the pension could be revised because the insured would have worked full-time if healthy, even without a change in health condition.
Decisione estratta
Yes. The relevant revision ground was a change in status from mixed to full-time employment, not a medical deterioration or improvement.
Motivazione estratta
The previous invalidity assessment method does not preclude later revision. The insured's own statements and personal circumstances supported the finding that she would have increased her employment to 100% if healthy; therefore the comparison basis changed under Art. 17 ATSG.
