Where the amount which a landlord is liable to pay as compensation for an improvement under this Part of this Act has been determined by agreement or by an award of the tribunal, and the landlord had before the passing of this Act granted or agreed to grant a reversionary lease commencing on or after the termination of the then existing tenancy, the rent payable under the reversionary lease shall, if the tribunal so directs, be increased by such amount as, failing agreement, may be determined by the tribunal having regard to the addition to the letting value of the holding attributable to the improvement:
The reversionary lessee shall have the same right of objection to the proposed improvement and of appearing and being heard at any proceedings before the tribunal relative to the proposed improvement as if he were a superior landlord, and if the amount of compensation for the improvement is determined by the tribunal, any question as to the increase of rent under the reversionary lease shall, where practicable, be settled in the course of the same proceedings.
