Questione giuridica chiave
Whether the conditions for revising and suppressing the invalidity pension under Art. 17 LPGA were met.
Decisione estratta
The lower court did not perform the required comparison between the medical situation at the initial award and at the revision decision; the revision could not rest on the SMR examination alone.
Motivazione estratta
Revision requires a legally relevant change in health or earning capacity compared with the prior decision. The cantonal court merely adopted the current SMR conclusions and inferred improvement without a proper comparative analysis.
