The principal controversy on appeal involves the legal rent for the apartment. By an order of the Rent Administrator dated August 1, 1945, the rent on a “unit” basis was fixed at $50 a month. The Administrator’s order also provided for rentals per person, the rate per person for triple occupancy being $22.50. The order specified that “The unit rate applies whenever two or more occupants of a unit have entered into a joint agreement with the landlord as to the termination of the tenancy.” The landlord required each of the tenants, namely, the man and his wife and the 13-year-old daughter, to sign separate rental agreements and as a result contends that the $50 “unit” rental did not apply but that instead he was entitled to collect $22.50 a month from each member of the family, or a total of $67.50 a month. He did, in fact, collect this amount for the first month of the tenancy which began July 19, 1948.
