N.Y. Comp. Codes R. & Regs. tit. 22, § 202.59
(2) A separate note of issue shall be filed for each property for each tax year.
(e) Pretrial conference.
(1) At any time after filing of the note of issue and certificate of readiness, any party to a tax assessment review proceeding may demand, by application served on all other parties and filed with the court, together with proof of such service, a pretrial conference, or the court on its own motion may direct a pretrial conference at a time and date to be fixed by the court. At the pretrial conference, the judge shall take whatever action is warranted to expedite final disposition of the proceedings, including but not limited to:
(2) Failure to comply with any order or directive of the court authorized by this subdivision shall be subject to the appropriate sanctions.
(f) Consolidation or joint trial.
Consolidation or joint trial of real property tax assessment review proceedings in the discretion of the court shall be conditioned upon service having been made of the verified or certified income and expense statement, or a statement that the property is not income-producing, for each of the tax years under review.
(g) Exchange and filing of appraisal reports.
(1) The exchange and filing of appraisal reports shall be accomplished by the following procedure:
(4) Appraisal reports shall comply with any official form for appraisal reports that may be prescribed by the Chief Administrator of the Courts.
(h) Use of appraisal reports at trial.
Upon the trial, expert witnesses shall be limited in their proof of appraised value to details set forth in their respective appraisal reports. Any party who fails to serve an appraisal report as required by this section shall be precluded from offering any expert testimony on value; provided, however, upon the application of any party on such notice as the court shall direct, the court may, upon good cause shown, relieve a party of a default in the service of a report, extend the time for exchanging reports, or allow an amended or supplemental report to be served upon such conditions as the court may direct. After the trial of the issues has begun, any such application must be made to the trial judge and shall be entertained only in unusual and extraordinary circumstances.
(a) Applicability.
This section shall apply to every tax assessment review proceeding brought pursuant to title 1 of article 7 of the Real Property Tax Law in counties outside the City of New York.
(b) Statement of income and expenses.
Before the note of issue and certificate of readiness may be filed, the petitioner shall have served on the respondent, in triplicate, a statement that the property is not income-producing, or a copy of a verified or certified statement of the income and expenses on the property for each tax year under review. For the purposes of this section, a cooperative or condominium apartment building shall be considered income-producing property; an owner-occupied business property shall be considered income-producing as determined by the amount reasonably allocable for rent, but the petitioner is not required to make an estimate of rental income.
(c) Audit.
Within 60 days after the service of the statement of income and expenses, the respondent, for the purpose of substantiating petitioner's statement of income and expenses, may request in writing an audit of the petitioner's books and records for the tax years under review. If requested, the audit must be completed within 120 days after the request has been made unless the court, upon good cause shown, extends the time for the audit. Failure of the respondent to request or complete the audit within the time limits shall be deemed a waiver of such privilege. If an audit is requested and the petitioner fails to furnish its books and records within a reasonable time after receipt of the request, or otherwise unreasonably impedes or delays the audit, the court, on motion of the respondent, may dismiss the petition or petitions or make such other order as the interest of justice requires.
(d) Filing note of issue and certificate of readiness; additional requirements.
