In this Act unless there is anything repugnant to the subject or context, 479 (3) "landlord" means any person who is for the time being, receiving, or entitled to receive, rent in respect of any premises whether on his own account or on account, or on behalf, or for the benefit of any other person or as a trustee, guardian, or receiver for any other person or who would so receive the rent or be entitled to receive the rent if the premises were let to a tenant, and includes any person not being a tenant who from time to time derives title under a landlord and further includes in respect of his sub tenant, a tenant who has sub let any premises; (and also includes in respect of a licensee deemed to be a tenant by section 15A, the licensor who has given such licence;)" Whether the expression 'landlord ' in sub section (1) of section 13 of the Act cannot be said to include 'an usufructuary mortgagee ' where the tenanted premises is the subject of usufructuary mortgage, is the question which requires our answer in the light of the provisions of the Act.
