Question juridique clé
Admissibility of the federal appeal against the cantonal decision on procedural security
Solution extraite
The appeal was inadmissible because the appellants failed to show, as required for an incidental decision, that the conditions of Art. 93(1) LTF were met.
Motifs extraits
A security order is in principle an appealable incidental decision only if irreparable harm or immediate final resolution is demonstrated. The burden to plead and prove this lies with the appellant, which was not done here.
