Key legal question
Whether objections beyond formal grounds could be raised against the appointed medical expert in this interlocutory appeal.
Extracted holding
Only formal grounds for disqualification or recusal of the proposed expert were reviewable; objections about expert competence, scope of expertise, or questionnaire content were not part of the appealable issue.
Extracted reasoning
Under Art. 44 ATSG and the case law on interlocutory decisions, only objective grounds suggesting bias or dependence can be raised; substantive evidentiary objections belong to the merits stage.
