On August 5, 2026, the Appellate Division of the Supreme Court of the State of New York ruled in the case of Abingdon Realty Co., LLC v. Finkelshteyn, affirming a lower court's decision that denied an appeal from defendant Yan Finkelshteyn. This ruling affects both parties involved in a lengthy legal battle over a sublease agreement for an apartment in Brooklyn. The court's decision highlights the importance of adhering to procedural rules in legal cases.

The dispute began when Abingdon Realty Co., LLC, the plaintiff in the case, filed a lawsuit against Finkelshteyn in December 2019. The lawsuit aimed to recover damages for breach of a sublease and sought attorneys' fees. The sublease agreement, which was executed in August 2008, had been renewed several times. However, the legal proceedings became complicated when Finkelshteyn failed to respond to several motions made by Abingdon Realty.

In December 2021, Finkelshteyn attempted to enlarge the time to take his deposition, but the Supreme Court denied this request. Following that, the case was marked off the calendar, prompting Abingdon Realty to seek to restore the action in January 2024. The court granted this request on February 7, 2024, allowing the case to proceed and ordering Finkelshteyn to appear for a deposition by May 1, 2024.

However, Finkelshteyn's attorney requested an adjournment of the deposition, citing a vacation and Finkelshteyn's medical condition as reasons for his inability to attend. The defendant did not oppose the plaintiff's motion, which led to the court granting Abingdon Realty's unopposed motion on April 2, 2024. Finkelshteyn later sought to vacate this order, claiming he had a reasonable excuse for his default.

The court ruled on June 6, 2024, denying Finkelshteyn's motion. The judges on the panel included Valerie Brathwaite Nelson, Helen Voutsinas, Janice A. Taylor, and Donna-Marie E. Golia. The court stated, "A party seeking to vacate an order entered upon his or her default in opposing a motion must demonstrate a reasonable excuse for the default and a potentially meritorious opposition to the motion."

The judges found that Finkelshteyn failed to provide a reasonable excuse for not opposing the motions. His attorney's vacation was not deemed sufficient justification for the default. The court emphasized that the proper procedure for addressing a default is to file a motion to vacate the default, which Finkelshteyn did not adequately demonstrate.

This ruling has significant implications for similar cases in the future. It underscores the necessity for parties to be diligent in responding to motions and adhering to court schedules. Failure to do so can lead to unfavorable outcomes, as seen in Finkelshteyn's case. The decision also reinforces the importance of providing valid reasons for any defaults in court proceedings.

Going forward, this ruling may serve as a precedent for other cases involving procedural defaults. It highlights that courts expect parties to take their legal obligations seriously and respond appropriately to motions. The ruling may deter others from neglecting their responsibilities in legal proceedings, knowing that courts are unlikely to grant leniency without compelling reasons.

Finkelshteyn may still have options for appeal, but details regarding further legal action were not available in the court filing. It remains to be seen whether he will pursue additional avenues to challenge the court's decision.
