Questione giuridica chiave
What is the relevant reference point for assessing a change justifying pension revision?
Decisione estratta
The relevant reference point is the last legally binding decision based on a proper merits review; a later household-based decision without new medical assessment is not decisive for the health-status comparison.
Motivazione estratta
The court held that the earlier medical basis from 1991/1998 remained relevant because the household decision in 2007 did not involve a fresh medical evaluation, whereas the later record showed a significant psychiatric improvement.
