Questão jurídica principal
Whether the appeal against the order appointing medical experts was admissible before the Federal Supreme Court.
Decisão extraída
Only formal recusal issues concerning an expert are independently appealable; the appellant's objections were too general and did not raise a cognizable formal recusal ground.
Fundamentação extraída
The challenge concerned the institution and alleged systemic concerns, not specific formal disqualification grounds. Such matters can be reviewed later together with the final merits decision.
