Question juridique clé
Whether the federal appeal against the cantonal remittal decision was admissible
Solution extraite
The decision was interlocutory and did not cause irreparable prejudice or justify immediate review to avoid lengthy and costly evidence proceedings.
Motifs extraits
Under Art. 93 LTF, an ordinary or subsidiary constitutional appeal against an interlocutory decision is admissible only under narrow conditions. Those conditions were not met here, so the appeal was manifestly inadmissible under Art. 108 para. 1 let. a LTF.
