Questione giuridica chiave
Whether the appeal was admissible against the cantonal decision confirming rectification of a superprovisional provisional lien registration order.
Decisione estratta
The appeal was inadmissible because a decision authorizing provisional registration of a builders' lien, including one issued superprovisionally, is an incidental conservatory measure not meeting the requirements for federal appeal.
Motivazione estratta
Such an order does not finally dispose of the merits and does not cause irreparable legal prejudice within the meaning of Art. 93 LTF; it is only a provisional step pending an action on the merits for definitive registration.
