Questão jurídica principal
Whether a revision of the disability pension was justified due to a material improvement in health and earning capacity.
Decisão extraída
A revision ground existed; the appellant's psychiatric condition had improved and his work capacity on the balanced labour market had increased from 0% to 50%.
Fundamentação extraída
Under Art. 17 ATSG, any substantial change since the last final award permits revision. The changed health situation and its effect on capacity were undisputed.
