Section 9(4)(d) in The Bihar Government Estates (Khas-Mahal) Manual, 1953
(d)Subject to clause (v) (b) below, where permission is taken for converting agricultural land into building sites.(iii)A person, who converts agricultural land into building sites without permission whether he be the original raiyat or a transferee is liable under the tenancy law to eviction for changing the character of the land. Such person should not be allowed to continue to hold the converted land on a purely agricultural rent and to appropriate the whole increment in value such cases may be dealt with either by making surrender a condition precedent to any sale of agricultural land for purposes other than agricultural or else by ejecting the transferee formally and resettling with him on a town lease. In either case, a substantial salami should be charged on resettlement. But to avoid hardship the Collector may agree to the transfer of part of his land by an old established raiyat without cancellation of his tenancy on receipt of a Salami on a moderate scale which should be fixed with the sanction of the Commissioner in each individual case.(iv)Salami will ordinarily be levied on original leases but where the progressive increase in the value of land or other special circumstances justify it a fresh salami may be taken for the renewal of a lease. When salami is taken for the renewal of a lease, it should include not only the share of Government in the progressive increase in value anticipated within the period of the lease to be renewed but also a sum equivalent to their share in the known increment in value due to causes (e.g., capital and enterprise of Government and third parties in developing the place and providing amenities for it) which were not anticipated when the lease was originally granted or previously renewed.
