Questione giuridica chiave
Whether the revision of the disability pension under Art. 17 ATSG was justified by an improved health and work capacity.
Decisione estratta
The cantonal court could rely on the record to find a significant improvement and a revision ground under Art. 17 ATSG; the reduction to a three-quarter pension was therefore warranted.
Motivazione estratta
The RAD report was coherent and sufficiently reasoned. Divergent medical opinions did not establish obvious incorrectness, especially since even one treating physician had initially considered daily office work possible.
