Mere continuance of possession by the subtenants lawfully inducted by the tenant with the written consent of the landlady contained in rent note does not afford any ground to the landlady for eviction of the tenant on the ground of sub letting, as the tenant has not sub let after the commencement of the Act any por tion without the consent in writing of the landlady." (emphasis supplied) Of all the decisions cited at the Bar, this decision is, admittedly, nearest on facts to the present case with the only difference that the sub letting in the present case was after expiry of the contractual tenancy and after the com mencement of the Act prohibiting subletting without the written consent of the landlord when it was made on 1.4.1948, while the sub letting in Mahabir Prasad 's case (supra) was during the period of contractual tenancy when the express written consent of the landlord for sub letting was available.
