Goodman, 47 A.2d 516, 517 (D.C. 1946); 1 MILTON R. FRIEDMAN, FRIEDMAN ON LEASES § 7.703 (1990) ("Termination of Prime Lease — Effect on Sublease") [hereinafter FRIEDMAN]. Therefore, upon the valid termination of the master lease by Lessor, both Tenant's and Subtenant's rights to further lawful possession of the premises came to an end.
Jones, Landlord and Tenant, 1st Ed. 1906, § 367. Camp v. Goodman, D.C.Mun.App., 47 A.2d 516. The principal point raised by this appeal is whether the defendant has raised a valid defense to an action for possession based on non-payment of rent. It is well established that in ruling on a motion for a directed verdict the trial court must consider the evidence introduced by the party against whom the verdict is sought as true, and view all the evidence in the light most favorable to him, giving him the benefit of all reasonable inferences therefrom.
