Rule 12-25 Official Notice.
(a) In reaching a decision, the hearing officer may take official notice, before or after submission of the case for decision, on request of a party or sua sponte on notice to the parties, of any fact which may be judicially noticed by the courts of this state. Matters of which official notice is taken shall be noted in the record, or appended thereto. The parties shall be given a reasonable opportunity on request to refute the officially noticed matters by evidence or by presentation of authority.
(b) Official notice may be taken, without notice to the parties, of rules published in the Rules of the City of New York or in The City Record. In addition, all parties are deemed to have notice that official notice may be taken of other regulations, directives, guidelines, and similar documents that are lawfully applicable to the parties, provided that any such materials that are unpublished are filed with the hearing officer sufficiently before commencement of the hearing to enable all parties to address at the hearing any issue as to the applicability or meaning of any such materials.
