Liаm leаsed аn apartment tо Tara оn a mоnth-to-month basis beginning on the first of the month, with rent payable monthly. Five months into the lease, Tara failed to pay rent. Liam then sued Tara for possession for nonpayment of rent. Tara successfully defended this suit on the ground that the apartment was uninhabitable and that, accordingly, no rent was properly payable. On May 7, immediately following the court order in Tara’s favor, Liam served Tara with a written but not notarized notice to terminate the tenancy and to vacate the apartment on or before June 30. On July 1, Tara was still in possession, nothing had changed, and Liam brought an appropriate action for possession. Tara prevailed.What is the most likely reason for the court’s decision?
