Derogation from grant is a common law concept requiring a grantor (the person who grants the benefit) not to do anything that substantially deprives the grantee (the person who has the benefit of the grant) from the enjoyment of the benefit granted for example an easement over land such as a right of way.
The doctrine is applied to many landlord and tenant matters where the obligation not to derogate from grant is implied into leases to stop landlords doing something that may have the effect of making the property less fit for the purpose for which the lease was granted.
In addition the doctrine of derogation of grant also applies where there is a grant of an easement. In this case the grantor is stopped from doing anything that substantially deprives the grantee from the enjoyment of the benefit granted by the easement.
However, the courts have stated that while the doctrine of derogation from grant requires the grantor not to take any action that deprives the grantee from exercising the easement granted it does not require any positive action to be taken by the grantor.
The case of Carter v Coles  EWCA Civ 398 concerned the sale of land by the Carters to the Coles. The Carters retained part of their land that was let to a water bottling company and reserved an easement over the land sold to the Carters to permit lorries visiting the retained land to gain access to and from the water bottling company’s plant on the land. The planning permission for the business required a visibility splay to be maintained.
There was an existing one in place when the sale was transacted. However, as a result of the Coles planting various shrubs and erecting a fence on the visibility splay that obscured the visibility splay the Local Authority refused to renew the planning permission with the consequence that the Carter’s tenants could not operate the business any longer from the land and left. The court held that the Coles’ action amounted to a derogation from grant as the planting of shrubs and the erection of the fence had the practical effect of preventing the use of the easement.
