1) Tulk, the original owner of some houses, sold a piece of land to E with a covenant that the land would remain an ornamental garden with no buildings. 2) Over time, the land was sold multiple times until it was purchased by Moxhay, who had notice of the covenant but attempted to build on the land. 3) The court held that in equity, the covenant was binding on subsequent purchasers like Moxhay, and enforced the covenant by injunction, since Tulk had a legitimate interest and Moxhay had notice.
