Question juridique clé
Whether a public law appeal is admissible against the cantonal court's remand order under Art. 87 OJ.
Solution extraite
The remand order was an incidental decision and could be challenged only if it caused irreparable harm, which was not shown.
Motifs extraits
A remand for further investigation and a new decision is merely a procedural step; the challenged judgment caused no specific irreparable prejudice, so Art. 87 OJ barred immediate review.
