Question juridique clé
Whether the federal appeal against the pre-provisional custody order was admissible without first seeking the cantonal provisional decision under Article 401 CPC/VD and Article 75 LTF.
Solution extraite
No. The order was incident; the cantonal procedure to obtain a provisional decision replacing the emergency order had to be exhausted first.
Motifs extraits
The challenged emergency order would be replaced by a subsequent provisional order after hearing the parties. This cantonal remedy could undo the alleged prejudice, and nothing in the law excluded retroactive effect of a revocation.
