This Appellate Division Case points up how the court  treats just one too many mistakes.  Default, followed by failure to oppose a motion followed by….  The court uses the phrase "pattern of willful default.

"To vacate the order dated February 18, 2005, entered upon the plaintiffs’ default in opposing the appellants’ motion pursuant to CPLR 3042 and 3126 to dismiss the complaint insofar as asserted against them, the plaintiffs were required to demonstrate both a reasonable excuse for their default and a meritorious cause of action (see CPLR 5015[a][1]; Watson v New York City Tr. Auth., 38 AD3d 532; Echevarria v Waters, 8 AD3d 330, 331). Although the Court may, in its [*2]discretion, accept law office failure as a reasonable excuse (see CPLR 2005; Putney v Pearlman, 203 AD2d 333), "’a pattern of willful default and neglect’ should not be excused" (Roussodimou v Zafiriadis, 238 AD2d 568, 569, quoting Gannon v Johnson Scale Co., 189 AD2d 1052). Here, the plaintiffs’ attorney’s failure to respond to the demand for a bill of particulars, to timely comply with the preliminary conference order dated September 14, 2004, and to oppose the appellants’ motion to dismiss the complaint, and his further one-year delay in moving to vacate the order dated February 18, 2005, constituted a pattern of willful default and neglect that cannot be excused (see Diamond v Vitucci, 36 AD3d 650; Amato v Fast Repair, Inc., 15 AD3d 429, 430; Santiago v New York City Health & Hosps. Corp., 10 AD3d 393, 394). Under these circumstances, the Supreme Court improvidently exercised its discretion in granting the plaintiffs’ motion to vacate the order dated February 18, 2005, entered upon their default. "
