§ 226. Effect of renewal on sub-lease. The surrender of an under-lease is not requisite to the validity of the surrender of the original lease, where a new lease is given by the chief landlord. Such a surrender and renewal do not impair any right or interest of the chief landlord, his lessee or the holder of an under-lease, under the original lease; including the chief landlord's remedy by entry, for the rent or duties secured by the new lease, not exceeding the rent and duties reserved in the original lease surrendered.
