Indian Encasements Act, 1882
43. Extinction by permanent change in dominant heritage
Where by, any permanent change in the dominant heritage, the burden on the servant heritage is materially increased and cannot be reduced by the servant owner without interfering with the lawful enjoyment of the easement, the easement is extinguished unless-
(a) it was intended for the beneficial enjoyment of the dominant heritage, to whatever extent the easement should be used; or
(b) the injury caused to the servant owner by the change is so slight that no reasonable person would complain of it; or
(c) the easement is an easement of necessity.
Nothing in this section shall be deemed to apply to an easement entitling the dominant owner to support of the dominant heritage.
