Questione giuridica chiave
Whether the double auction was admissible because the pledgee's priority over the usufruct should have been challenged in supervisory proceedings.
Decisione estratta
The complaint could not succeed on that ground; the appellant raised issues concerning the substantive rank of the usufruct, which had to be pursued in charge-register settlement proceedings, not by supervisory complaint.
Motivazione estratta
Supervisory review is limited to formal defects or inconsistencies with the land register or claims; disputes over existence, scope, rank, or enforceability of a right belong to the settlement procedure. In enforcement, the ranking of servitudes and pledge rights follows the dates of registration.
