Question juridique clé
Whether the cantonal ruling refusing most evidence requests was immediately appealable by public-law appeal.
Solution extraite
The decision was interlocutory and, under Art. 87 OG, was appealable only if it caused irreparable legal harm, which was not shown.
Motifs extraits
Refusal of evidence usually causes only factual disadvantages such as delay or higher costs; such consequences are not irreparable legal prejudice.
