The Supreme Court of the State of New York may also remove local officials, as provided in Section 36 of the PBO:§ 36. Removal of town, village, improvement district or fire district officer by court. Any town, village, improvement district or fire district officer, except a justice of the peace, may be removed from office by the supreme court for any misconduct
, maladministration, malfeasance or malversation in office. An application for such removal may be made by any citizen resident of such town, village, improvement district or fire district or by the district attorney of the county in which such town, village or district is located, and shall be made to the appellate
division of the supreme court held within the judicial department embracing such town, village, improvement district or fire district. Such application shall be made upon notice to such officer of not less than eight days, and a copy of the charges upon which the application will be made must be served with such notice.So you will need to file the application for removal with the NY Supreme Court and you will need to provide notice to the trustee being removed. You must file it in the county where your village board is located. In New York, of course, the "supreme" court is the trial court.
