It is well-settled law that an attorney may not be compensated for services rendered a municipal board or officer unless he has been retained in accordance with statutory authority. ( Seif v. City of Long Beach, 286 N. Y. 382; Lyddy v. Long Is. City, 104 N. Y. 218; Konnoson v. City of New York, 254 App. Div. 378, affd. 281 N. Y. 716; People ex rel. French v. Town, 1 App. Div. 127; Ann. 2 A. L. R. 1212; 56 Am. Jur. 2d, Municipal Corporations, § 279.) In other words, the power to employ counsel by a municipal board or officer is not deemed to be incidental to such board or officer. Rather, express authority, either by statute or by appropriate resolution of the governing body, must be shown to justify the retention of an attorney by a municipal board or officer. ( Matter of Kay v. Board of Higher Educ. of City of N. Y., 260 App. Div. 9; Reynolds v. Village of Ossining, 102 App. Div. 298; People ex rel. Sherrill v. Guggenheimer, 47 App. Div. 9; see, also, 10 McQuillin, Municipal Corporations [1966 ed.], § 29.16, pp. 280-281.) The salient purpose underlying this rule is, of course, to ensure responsible municipal government. Not only is it designed as a safeguard against the extravagance or corruption of municipal officials, as well as against their collusion with attorneys (cf. Seif v. City of Long Beach 286 N. Y. 382, supra, at pp. 387-388; Dickinson v. City of Poughkeepsie, 75 N. Y. 65, 74-75; McDonald v. Mayor of City of N. Y., 68 N. Y. 23, 28-29), but also, to prevent confusion and contradiction in the direction of the municipality's litigation (cf. Matter of Collins v. Village of Saratoga Springs, 70 Hun 583, affd. 140 N. Y. 637; Adee v. Arnow, 91 Hun 329).
