Now, probing the merits of the contention, the first thing that stares in the face is whether where a suit is filed by a person claiming to be landlord on the ground that he in good faith requires the suit premises for his own use and occupation, would he still be entitled to a decree for possession on this ground even if during the course of proceedings his interest in the suit premises has come to an end and on the date of the final decree he had no subsisting interest in the suit premises? In other words, how should the Court approach a proceeding under the Rent Act while taking into consideration the subsequent events which would non suit the plaintiff? The expression 'landlord ' has been defined in section 2 (d) of the Rent Act which reads as under: "landlord" includes the persons who for the time being is receiving, or is entitled to receive, the rent of a building whether on his own account or on behalf of another, or on account or on behalf or for the benefit, or himself and others or as an agent, trustee, executor, administrator, 377 receiver or guardian or who would so receive the rent, or be entitled to receive the rent if the building were let to a tenant.
