Questão jurídica principal
Whether the psychiatric expert lacked impartiality because of an alleged economic dependence on the AI office.
Decisão extraída
No objective circumstances showed apparent bias; the challenge was untimely and unfounded.
Fundamentação extraída
Repeated appointments by an insurer do not by themselves prove partiality. The insured raised the bias objection only late and offered no specific facts overcoming the presumption of impartiality.
