Question juridique clé
Whether the cantonal court arbitrarily refused to consider the appellant’s recourse claims in the joinder procedure.
Solution extraite
Yes. Refusing to take the recourse claims into account, despite the admitted joinder and the procedural economy purpose, was arbitrary.
Motifs extraits
Under Geneva procedure and the cited doctrine, joinder may also serve to resolve conditional or related recourse claims. The court could use conditional condemnation; excluding the claims altogether disregarded the function of joinder.
