Questão jurídica principal
Whether the disability pension could be revoked under Art. 17 ATSG due to improved health status.
Decisão extraída
Yes. The court held that the insured person's mental condition had materially improved and no longer caused work incapacity, so the pension could be revoked under Art. 17 ATSG.
Fundamentação extraída
The Federal Court accepted the lower court's reliance on the psychiatric expert report and treating physician records. It found no arbitrary fact-finding and held that the comparison date was the original pension grant, not the later status review, because the latter did not involve a full medical reassessment.
