(5) A preclusion order may provide that it will be effective unless a proper bill is served within a specified time.
(b) Admissions.
(1) At any time after service of the answer, and not later than 20 days before the hearing, a party may serve upon any other party a written request for admission of the following: The request shall pertain to matters as to which the party requesting the admission reasonably believes there can be no substantial dispute at the hearing, and which are within the knowledge of the adverse party or can be ascertained by him or her upon reasonable inquiry. Copies of the papers, documents or photographs shall be served with the request unless copies have already been furnished.
(2) The party to whom the request to admit is directed may choose to respond by serving a statement expressly admitting the matters in question. However, the party is deemed to admit each of the matters as to which an admission was properly requested unless, within 20 days after service of the request, or within such further time as the supervising administrative law judge may allow, the party to whom the request is directed serves upon the party requesting the admission, a verified statement:
(3) Any admission made, or deemed to be made, by a party pursuant to a request made under this section, is for the purpose of the pending proceeding only, and does not constitute an admission for any other purpose, nor may it be used in any other proceeding in the Division of Tax Appeals. The administrative law judge designated by the tribunal may, at any time, allow a party to amend or withdraw any admission on such terms as may be just. Any admission shall be subject to all pertinent objections to admissibility which may be interposed at the hearing.
(c) Depositions to perpetuate testimony.
A party to a case pending in the Division of Tax Appeals, who desires to perpetuate his own testimony or that of any other person or to preserve any document or thing, shall file an application pursuant to this section for an order of an administrative law judge authorizing such party to take a deposition for such purpose. Such depositions shall be taken only where there is a substantial risk that the person or document or thing involved will not be available at the hearing of the case, and shall relate only to testimony or document or thing which is not privileged and is material to a matter in controversy.
(1) The application. Content of application. The application to take a deposition shall be signed by the party seeking the deposition or his representative, and shall show the following:
(7) Use of deposition. At the hearing or in any other proceeding in the case, any part or all of a deposition, so far as admissible under the rules of evidence applied as though the witness were then present and testifying, may be used against any party who was present or represented at the taking of the deposition or who had reasonable notice thereof, in accordance with any of the following provisions:
(iii) The deposition may be used for any purpose if the parties have stipulated to the use of a deposition or if the administrative law judge finds:
(8) Depositions on written questions.
(iii) Copies of all written questions served shall be delivered by the party seeking the deposition to the office designated in the administrative law judge's order.
(d) Disclosure of evidence prior to a license revocation hearing.
When the Division of Taxation seeks the revocation of a license or permit, as such terms are used in section 401.4 of the State Administrative Procedure Act, either party shall, upon demand and at least seven days prior to the hearing, disclose the evidence that the party intends to introduce at the hearing, including documentary evidence and the identification of witnesses. The provisions of this subdivision shall not be deemed to require the disclosure of information or material otherwise protected by law from disclosure, including information and material protected because of privilege, the secrecy provisions of the Tax Law or confidentiality. If, after such disclosure, a party determines to rely upon other witnesses or information, the party shall, as soon as practicable, supplement its disclosure by providing the names of such witnesses or the additional documents.
