Question juridique clé
Whether the federal appeal against the Geneva preprovisional order was admissible despite the unexhausted cantonal remedy of requesting substitutive provisional measures.
Solution extraite
The appeal was inadmissible because the challenged order was not a last-canton-instance decision; the wife had to first seek provisional measures that could replace the preprovisional order.
Motifs extraits
Under Art. 75(1) LTF, cantonal remedies must be exhausted. Geneva procedure allowed provisional measures under Art. 381(4) LPC/GE to supersede the preprovisional order, so the cantonal path remained open.
