Questão jurídica principal
Whether the disability pension could be revised and revoked under Art. 17 ATSG due to a relevant change in the insured person's condition.
Decisão extraída
Yes. The court held that a legally relevant change occurred because depressive symptoms had improved so that work capacity was no longer substantially limited.
Fundamentação extraída
Revision requires any material change in the relevant factual basis. The psychiatric improvement was enough to trigger reassessment of the whole entitlement; a mere different assessment of unchanged facts was not the case here.
