Tenant Maintained Primary Residence Despite Spending Nights at Girlfriend's

Landlord sued to evict rent-stabilized tenant for nonprimary residence. Landlord claimed that tenant illegally sublet his apartment while living at his girlfriend's apartment more than half of the prior year. The court ruled against landlord after a trial. Tenant submitted many documents showing that he used the apartment during the period in question. He kept all of his personal belongings in his apartment and occasionally spent nights at his girlfriend's apartment.
