Questione giuridica chiave
Whether the full disability pension could be revised and revoked because of a material improvement in health
Decisione estratta
No proven material improvement was shown with the degree of probability required in social insurance law; the pension could not be revoked.
Motivazione estratta
The medical record did not establish a decisive improvement between the relevant comparison dates. The treating rheumatologist's view was insufficiently reasoned, the available imaging did not show relevant changes, and no convincing neurological/neurosurgical assessment supported revision.
