—[*1] Peluso & Touger, LLP, New York City (Pei Pei Cheng of counsel), for appellant.

Robert M. Morgenthau, District Attorney, New York (Susan C. Roque of counsel), for respondent.

Order, Supreme Court, New York County (Eileen A. Rakower, J.), entered July 30, 2007, which granted the motion of nonparty respondent New York County District Attorney's Office to quash a subpoena seeking the deposition of an assistant district attorney (ADA) in an action against defendant City, unanimously affirmed, without costs.

The quashing of the subpoena was a proper exercise of judicial discretion (see Allen v Crowell-Collier Publ. Co., 21 NY2d 403, 406 [1968]). Plaintiff failed to establish that the ADA's deposition testimony as to her motives for charging plaintiff with possession of a forged instrument in an underlying criminal action, and instructing the grand jury in the way she did, is "material and necessary" to this malicious prosecution action against the City (CPLR 3101 [a]; see generally Blittner v Berg & Dorf, 138 AD2d 439 [1988]). Such an action based on the allegedly malicious or improper acts of an ADA cannot stand where, as here, the actions complained of are associated with "the prosecutorial phase of the criminal process," and are thus subject to absolute immunity (Johnson v Town of Colonie, 102 AD2d 925, 926 [1984]; see generally Drakeford v City of New York, 6 AD3d 302 [2004], appeal dismissed 2 NY3d 779 [2004], cert denied 543 US 909 [2004], appeal dismissed and lv denied 3 NY3d 731 [2004]).

In view of the foregoing, it is unnecessary to address whether the motion was properly granted based on the attorney work-product privilege (see CPLR 3101 [c]). However, were we to address the issue, we would find that such privilege applies to protect the ADA from disclosing [*2]her "mental impressions, conclusions, opinions or legal theories" (CPLR 3101 [d] [2]) in the underlying criminal action.
