Question juridique clé
How the registered easement 'right to build closer, higher and on the boundary' must be interpreted under Art. 738 ZGB
Solution extraite
The land register entry is not clearly general; a project-related scope remains plausible, so the lower court could examine the deed of acquisition.
Motifs extraits
The wording did not unambiguously establish a blanket right. Given the common easement for 43 parcels and the unusual breadth of an unrestricted right, the cantonal court was not arbitrary in finding ambiguity and consulting the underlying deed.
