Questão jurídica principal
Whether the easement had lost all utility under Art. 736(1) CC or only reduced utility under Art. 736(2) CC
Decisão extraída
The easement had lost all utility because its exercise had become impossible after the owner's renovations.
Fundamentação extraída
The access door remained physically present but now opened onto a void and could no longer be used. The cantonal court should therefore have relied on Art. 736(1) CC, not Art. 736(2) CC.
