This appeal is from judgments entered in consolidated actions between the parties tried in the Landlord and Tenant Branch of Superior Court. First, appellee-tenant sued her landlord demanding that their rental agreement be set aside and the rent she had paid to the landlord be refunded to her. Appellant-landlord then brought an action against the tenant to recover unpaid rent and for possession of the leased premises based upon the same unpaid rent. Thereafter, the tenant filed a motion for partial summary judgment, seeking to establish her entitlement to a refund of the amount of rent she had paid her landlord. The trial court granted the motion, finding the rental agreement between the parties void because of the landlord’s failure to obtain the required housing licenses before leasing the property. 1
