Questão jurídica principal
Whether the cantonal court arbitrarily found no relevant change in the appellant's health and financial situation.
Decisão extraída
No arbitrariness was shown: the medical certificate did not clearly establish a significant worsening, and AI steps were only contemplated.
Fundamentação extraída
The Federal Court held that the certificate merely confirmed an ongoing illness with reduced work capacity, without proving a material deterioration or prospects of recovery; therefore the cantonal finding was not untenable.
