"An applicant for modification or discharge of a restrictive covenant where his ground is that provided for in section 3(1)(b) has a burden imposed on him to show that the permitted user is no longer reasonable and that another user which would be reasonable is impeded... Lord Evershed M.R. In re Ghey and Galton's Application [1957] 2 Q.B. 650, 633 expressed the view that in relation to this ground - `it must be shown, in order to satisfy this requirement, that the continuance of the unmodified covenants hinders, to a real, sensible degree, the land being reasonably used, having due regard to the situation it occupies, to the surrounding property, and to the purpose of the covenants'. Put another way, the restrictions must be shown to have sterilised the reasonable use of the land. Can the present restrictions prevent the land being reasonably used for purposes the covenants are guaranteed to preserve?"
