Questão jurídica principal
Whether the revision of the full disability pension to a quarter pension was lawful.
Decisão extraída
The health condition had materially improved and the insured person was fully capable of working in adapted work; the revised invalidity degree of 43% justified only a quarter pension.
Fundamentação extraída
The lower court’s assessment of the medical evidence was not manifestly incorrect; additional medical examinations were unnecessary. The challenged income comparison and 10% deduction from the statistical wage involved discretionary assessment, and no legal error was shown.
