Ordered that the order is affirmed insofar as appealed from, with costs.
Contrary to the appellants' contention, the respondents were not required to move to vacate or modify the objectionable demand for a bill of particulars ( see CPLR 3042 [a]; compare CPLR former 3042 [a]; see also Siegel, Supp Practice Commentaries, McKinney's Cons Laws of NY, Book 7B, CPLR C3042:3, 2004 Pocket Part, at 165). The Supreme Court providently exercised its discretion in denying that branch of the appellants' motion which was to compel service of a bill of particulars as to the respondents' affirmative defenses since the demand was improper ( see Hillside Equities v. UFH Apts., 297 AD2d 704; Harrell v. County of Nassau, 227 AD2d 590, 591; Bharwani v. del Rosario, 180 AD2d 704; Kwang Sik Kim v. A K Plastic Prods., 133 AD2d 219). The Supreme Court was not required to prune the appellants' improper demand ( see Renucci v. Mercy Hosp., 124 AD2d 796).
