Questão jurídica principal
Whether the supervisory authority had to recuse because the newly appointed replacement curator had previously represented its president in another matter
Decisão extraída
No objectively ascertainable appearance of bias was shown; the prior lawyer-client relationship was unrelated to the present dispute and did not justify recusal.
Fundamentação extraída
A judge is disqualified only where objectively verifiable circumstances create an appearance of partiality. The mere fact that the replacement curator had once been the magistrate's lawyer, without any link to the present case, was insufficient.
