Key legal question
Whether the public law appeal against the cantonal interlocutory order was admissible under Art. 87 OG
Extracted holding
The challenged order was an interlocutory decision on evidence that did not cause irreparable legal harm, so the appeal was inadmissible.
Extracted reasoning
Orders concerning evidence are, in principle, interlocutory. Even if attacked only as to costs and compensation, they remain interlocutory and do not create irreparable harm because the costs issue can still be reviewed later and the alleged prejudice is tied to the merits of the evidence ruling.
