Kernrechtsfrage
Whether the cantonal court arbitrarily interpreted the building servitude and denied an interim ban on the works.
Extrahierter Entscheid
The appellant did not show that the cantonal court's interpretation of the servitude was unsustainable; the extension was plausibly not an 'other building' and did not plausibly violate the agreed use.
Extrahierte Begründung
In interim proceedings, the judge only assesses prima facie merits. The appellant failed to demonstrate arbitrariness in the finding that the works were an extension of an existing building, not a new building, and that the use restriction for one family was not likely breached.
