“(i) It applies to a defined area. (ii) Owners of properties within that area have purchased their properties from a common owner. (iii) Each of the properties is burdened by covenants which were intended to be mutually enforceable as between the several owners. (iv) The limits of that defined area are known to each of the purchasers. (v) The common owner is himself bound by the scheme, which crystallises on the occasion of the first sale of a plot within the defined area, with the consequence that he is not entitled to dispose of plots within that area otherwise than on the terms of the scheme. (vi) The effect of the scheme will bind future purchasers of land falling within the area, potentially for ever.”
“(1) the identification of the land to which the scheme relates, and (2) an acceptance by each purchaser of part of the lands from the common vendor that the benefit of the covenants into which he has entered will inure to the vendor and to others deriving title from him and that he correspondingly will enjoy the benefit of covenants entered into by other purchasers of part of the land.”
“Thus far, the cases in which schemes of mutual covenant have been found to exist have been cases where there is something in the conveyance or other transactional documents to alert a purchaser to the existence of the scheme. However, there are undoubtedly statements in the cases that the existence of a scheme may be inferred purely from the circumstances surrounding the initial sales. One particular circumstance is where the common vendor intends to sell the whole of his land simultaneously (e.g. by auction), because in that kind of case there is no point in his taking restrictive covenants (which he will not be able to enforce) unless they were intended to be mutually enforceable by the purchasers: Nottingham Patent Brick and Tile Co v Butler(1885) 15 QBD 261 , 269 (Wills J);(1886) 16 QBD 778 , 785 (Lord Esher MR).”
“I pass, therefore, to the consideration of the question whether the plaintiffs can enforce these restrictive covenants. In my judgment, in order to bring the principles of Renals v. Cowlishaw and Spicer v. Martin into operation it must be proved (1) that both the plaintiffs and defendants derive title under a common vendor; (2) that previously to selling the lands to which the plaintiffs and defendants are respectively entitled the vendor laid out his estate, or a defined portion thereof (including the lands purchased by the plaintiffs and defendants respectively), for sale in lots subject to restrictions intended to be imposed on all the lots, and which, though varying in details as to particular lots, are consistent and consistent only with some general scheme of development; (3) that these restrictions were intended by the common vendor to be and were for the benefit of all the lots intended to be sold, whether or not they were also intended to be and were for the benefit of other land retained by the vendor; and (4) that both the plaintiffs and the defendants, or their predecessors in title, purchased their lots from the common vendor upon the footing that the restrictions subject to which the purchases were made were to enure for the benefit of the other lots included in the general scheme whether or not they were also to enure for the benefit of other lands retained by the vendors. … I may observe, with reference to the third point, that the vendor's object in imposing the restrictions must in general be gathered from all the circumstances of the case, including in particular the nature of the restrictions. If a general observance of the restrictions is in fact calculated to enhance the values of the several lots offered for sale, it is an easy inference that the vendor intended the restrictions to be for the benefit of all the lots, even though he might retain other land the value of which might be similarly enhanced, for a vendor may naturally be expected to aim at obtaining the highest possible price for his land. Further, if the first three points be established, the fourth point may readily be inferred, provided the purchasers have notice of the facts involved in the three first points; but if the purchaser purchases in ignorance of any material part of those facts, it would be difficult, if not impossible, to establish the fourth point.”
“It appears to me that, where land is put up to auction in lots, and two or more persons purchase according to conditions of sale containing restrictions of the character of those under consideration in the present case, it is very difficult to resist the inference that they were intended for the common benefit of such purchasers, especially where the vendor purposes (as in the present case) to sell the whole of his property. Where he retains none how can the covenants be for his benefit; and for what purpose can they be proposed except that each purchaser, expecting the benefit of them as against his neighbours, may be willing on that account to pay a higher price for his land than if he bought at the risk of whatever use his neighbour might choose to put his property to?”
