In Leggio v. Haggerty (1965) 231 Cal.App.2d 873, the court addressed the very different question whether, when an easement benefits more than one parcel of property, the acquisition by one person of title to the servient tenement and a release or quitclaim deed of the easement from some, but not all, owners of the dominant parcels extinguishes the rights of the owners of the other dominant parcels. The court concluded that the easement rights of the owners of other dominant parcels were not extinguished. (Leggio, at pp. 881-884.)
