Question juridique clé
Whether the public-law appeal against the cantonal decision on expert fees was admissible despite being interlocutory.
Solution extraite
The challenged decision was interlocutory and no irreparable legal harm was shown; the appeal was therefore inadmissible.
Motifs extraits
Under Art. 87(2) OJ, an interlocutory decision is reviewable only if it can cause irreparable prejudice. The fee order did not finally determine the allocation of costs, and any objections could be raised again against the final cantonal decision.
