Question juridique clé
Whether a status change in a disability pension revision requires a comprehensive reassessment of entitlement, including medical capacity and income assessment.
Solution extraite
Yes. Once a revision ground exists, the pension entitlement must be reassessed in full; the prior partial-time disability assessment cannot simply be transferred to a now assumed full-time status.
Motifs extraits
Art. 17 ATSG requires a complete new review when circumstances materially change. The cantonal court wrongly kept the earlier 75% restriction and applied it unchanged to a full-time status without fresh findings on work capacity and residual earning ability.
