Questão jurídica principal
Whether the insured person showed a material change in earning capacity justifying revision of his disability pension.
Decisão extraída
No significant change was proven; the invalidity rate remained 58%.
Fundamentação extraída
The alleged higher hypothetical pre-injury income and a larger deduction from the invalid income were not new, established revision grounds. The previous calculation already accounted for age and functional limits, and the difficulties in finding work were not an additional reduction factor.
