Questão jurídica principal
Whether the disability pension revision required a higher pension because the health condition had materially worsened.
Decisão extraída
No material worsening was proven; the insured remained fit for adapted work at 50%, so the pension increase was refused and the pension could be revoked on revision.
Fundamentação extraída
The court relied on consistent polydisciplinary reports showing stabilization, while the treating doctors' statements were based mainly on subjective complaints and lacked independent findings. No concrete indication of bias in the expert institution was shown.
