Key legal question
What is the correct reference date for assessing a revision of the disability pension?
Extracted holding
The comparison date is the last final merits-based decision, here the 4/6 June 2006 pension award, not the January 2008 notification.
Extracted reasoning
The 2008 notification followed an ex officio revision without a material reassessment and therefore could not replace the earlier formal decision as the comparison basis.
