Question juridique clé
Whether the constitutional appeal against the refusal of pre-trial evidence was admissible despite being directed against an interlocutory decision.
Solution extraite
The appeal was inadmissible because the challenged ruling was an interlocutory decision that could still be contested later and caused no irreparable legal harm.
Motifs extraits
Under Art. 87 OG, interlocutory decisions are only immediately challengeable if they may cause irreparable legal prejudice. Refused evidence requests do not create such prejudice, since the issue can be raised again at trial or in an appeal against the final cantonal judgment.
