Questão jurídica principal
Whether the complaint against the interim decision was admissible regarding the expert-recusal issue and other objections
Decisão extraída
The complaint was admissible only as to the challenge to the appointed expert; the other objections and the direct challenge to the lower prosecutorial order were not admissible.
Fundamentação extraída
Self-standing interim decisions on recusal may be challenged under Art. 92 BGG. Other objections concerning the expert mandate and document access fall under Art. 93 BGG, and no irreparable legal disadvantage was shown. The prosecutorial order was replaced by the cantonal appeal judgment.
