Questão jurídica principal
Whether the disability pension could be revoked on revision under Art. 17 LPGA
Decisão extraída
No revision ground existed because the experts described no notable change in health compared with the prior decision; the later assessment was only a different evaluation of an unchanged situation.
Fundamentação extraída
Revision requires a relevant modification of the factual circumstances. The experts expressly stated that the condition had not materially changed for about fifteen years, so Art. 17 LPGA was not met.
