Questione giuridica chiave
Whether a revision ground existed under Art. 17 ATSG and the pension could be revoked
Decisione estratta
A relevant improvement in the psychiatric condition existed; the invalidity degree was 18%, so no pension remained payable.
Motivazione estratta
The medical reports showed that depression had ceased and that work capacity in adapted work was 100%; the revised invalidity degree did not meet the threshold for a pension.
