Questione giuridica chiave
Whether the disability pension could be withdrawn on revision despite the cantonal court's finding of unchanged incapacity
Decisione estratta
The office did not show a legally relevant and sufficiently established change in health status; the revision withdrawal was therefore unjustified.
Motivazione estratta
The Federal Tribunal was bound by the cantonal factual findings absent manifest inaccuracy. The office merely reargued the probative value of its expert report and did not demonstrate any clear error in the lower court's assessment of the extensive medical record.
