Question juridique clé
Whether the cantonal supervisory authority could decide that the mortgage lien did not extend to sub-rents and annul the office notice on that basis.
Solution extraite
No. Questions about whether the lien covers rents or sub-rents are matters of substantive civil law for the civil judge, not for the office or supervisory authorities.
Motifs extraits
Under Arts. 152 LP and 91-93 ORFI, the office must secure contested rents and proceed under Arts. 106 ss LP; the merits of the lien’s extension and related defenses must be decided in civil proceedings.
