The IAS court properly exercised its discretion in granting the motion of plaintiff landlord for a default judgment against defendant guarantors based on its finding that defendants failed to demonstrate a justifiable excuse for their delay in answering the complaint seeking to enforce defendants' guarantee of the tenant's lease obligations, and that defendants failed to establish a meritorious defense. Their defenses had been previously rejected by the Civil Court, New York County in 114 W. 26th St. Assoc., L.P. v. Metropolis Fencing Sports Ctr., LLC (Index No. 080711/03), where it was determined that the tenant, with whom defendant guarantors are in privity, and of whom they are principals, lacked any defense to the landlord's nonpayment petition (CPLR 3012 [d]).
