N.Y. Comp. Codes R. & Regs. tit. 22 § 202.70.14
If the court's Part Rules address discovery disputes, those Part Rules will govern discovery disputes in a pending case. If the court's Part Rules are silent with respect to discovery disputes, the following Rule will apply. Discovery disputes are preferred to be resolved through court confer- ence as opposed to motion practice. Counsel must consult with one another in a good faith effort to resolve all disputes about disclosure. See Section 202.7. If counsel are unable to resolve any disclosure dispute in this fashion, counsel for the moving party shall submit a let- ter to the court not exceeding three single-spaced pages outlining the nature of the dispute and requesting a telephone conference. Such a letter must include a representation that the party has conferred with opposing counsel in a good faith effort to resolve the issues raised in the letter or shall indicate good cause why no such consultation occurred. Not later than four business days after receiving such a let- ter, any affected opposing party or non-party shall submit a responsive letter not exceeding three single-spaced pages. After the submission of letters, the court will schedule a telephone or in-court conference with counsel. The court or the court's law clerks will attempt to address the matter through a telephone conference where possible. The failure of counsel to comply with this rule may result in a motion being held in abeyance until the court has an opportunity to conference the matter. If the parties need to make a record, they will still have the opportunity to submit a formal motion.
