Appeal from a judgment of the Supreme Court at Special Term, entered February 27, 1979 in Albany County, which dismissed petitioners' application, in a proceeding pursuant to CPLR article 78, to cancel and vacate certain examinations held for the positions of senior attorney and associate attorney on June 19, 1977, and permanently enjoin the respondents from certifying eligible lists based upon such examinations and from making any appointments therefrom. In this CPLR article 78 proceeding brought to annul the results of a civil service essay examination, Special Term's consideration of copies of the examination submitted to it ex parte was improper (see Matter of Kurtz v. Krone, 22 A.D.2d 988; see, also, Coleman v. Coleman, 61 A.D.2d 757; cf. B.G. Equip. Co. v. American Ins. Co., 61 A.D.2d 247, 249, affd 46 N.Y.2d 811). Where, as here, disclosure is necessary for adequate judicial review, the examinations should be made available to petitioners (Matter of Dougherty v. Bahou, 67 A.D.2d 739, 741; Matter of Kurtz v. Krone, supra; Matter of Meaney v Kaplan, 19 A.D.2d 680) with appropriate safeguards against improper disclosure (Mundy v. Nassau County Civ. Serv. Comm., 70 A.D.2d 631, 632). Moreover, the actual criteria used in rating petitioners' examinations should be disclosed, as well as their application in the grading process. Only after such a disclosure will Special Term be in a position to determine whether triable issues of fact have been presented. Judgment reversed, on the law, without costs, and matter remitted for further proceedings not inconsistent herewith. Mahoney, P.J., Greenblott, Sweeney, Kane and Main, JJ., concur.
