Questão jurídica principal

Decisão extraída
No objective appearance of bias was shown; the alleged errors, even if real, did not amount to serious or repeated breaches justifying recusal.
Fundamentação extraída
Under the constitutional guarantee of an impartial tribunal, only objective circumstances creating an appearance of partiality matter. The complaints mainly concerned case-management and alleged procedural mistakes, which did not demonstrate prejudice.
