Questão jurídica principal
Admissibility of the federal appeal against the cantonal ruling on appointment of an expert
Decisão extraída
The appeal is inadmissible because the cantonal ruling does not decide formal grounds for challenge of the expert and therefore is not an appealable incidental decision in this respect.
Fundamentação extraída
Under Art. 92 ff. and Art. 93 LTF, only certain incidental decisions may be challenged immediately. No formal recusal grounds were decided here.
