Questão jurídica principal
Whether the appeal against the appointment of an expert was admissible despite being directed against a non-final interlocutory decision.
Decisão extraída
The complaint was inadmissible because the challenged decision on expert appointment did not cause irreparable legal harm.
Fundamentação extraída
Under Art. 93(1)(a) BGG, a non-final decision is only appealable if it can cause irreparable harm. The appointment of an expert normally does not do so, and the alleged lack of reasoning or loss of trust in the expert does not create such harm.
