Question juridique clé
Whether the cantonal remand decision on provisional mechanics' lien inscription was appealable to the Federal Supreme Court.
Solution extraite
The appeal was not admissible because the challenged remand decision was an incidental decision; if the lower court later authorizes provisional inscription, that later decision would itself not be appealable.
Motifs extraits
A decision authorizing provisional lien inscription is merely protective and does not end the case; a remand decision leaving further examination to the lower court is only incidental. Appeal against such a remand is available only if the eventual final decision would itself be open to federal appeal, which is not the case here.
