Questione giuridica chiave
Whether the cantonal remand decision on provisional mechanics' lien inscription was appealable to the Federal Supreme Court.
Decisione estratta
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.
Motivazione estratta
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.
