Questione giuridica chiave
Whether the disability pension could be revoked on revision grounds under Art. 17 ATSG.
Decisione estratta
The court held that a relevant improvement in health had been established; the original severe psychiatric impairment was no longer ascertainable, so revision was justified.
Motivazione estratta
The psychiatric expert report and supplementary report were comprehensive and persuasive. Diverging statements of the treating physician did not outweigh them, especially where different medical concepts were used. The income and activity comparison was not challenged successfully.
