Question juridique clé
Whether the federal complaint against the cantonal court's appointment of an expert was admissible as a separate appeal against an interlocutory decision.
Solution extraite
The complaint was not admissible because the challenged ruling was an interlocutory decision that could not be separately appealed under Articles 92 or 93 BGG.
Motifs extraits
The lower court had not decided an issue of jurisdiction or recusal. The appointment of an expert did not itself cause irreparable harm, and any objections could be raised again in an appeal against the final cantonal decision on the property value.
