A New York appellate court has upheld a ruling that requires Jay R. Deshmukh to resolve his disputes with Kasowitz Benson Torres LLP through arbitration. This decision, made on November 10, 2026, affects how legal disputes are handled within law firms, particularly regarding contractual agreements. The ruling emphasizes the importance of arbitration clauses in partnership agreements.

The case, Deshmukh v. Kasowitz Benson Torres LLP, filed under Index No. 653920/24, revolves around the interpretation of partnership agreements between Deshmukh and the law firm. The court's decision highlights the legal principle that when a new agreement clearly states it supersedes a previous one, the terms of the new agreement govern.

Background

Jay R. Deshmukh, the plaintiff in this case, had a professional relationship with Kasowitz Benson Torres LLP, a law firm based in New York. Deshmukh initially joined the firm in 2018 under a partnership agreement that did not include a clause for mediation or arbitration of disputes. However, after rejoining the firm in December 2023, he signed an amended and restated partnership agreement (APA) that included a provision requiring disputes to be resolved through mediation and, if that failed, through arbitration.

The dispute arose when Deshmukh sought to challenge the law firm on various matters. The firm moved to compel arbitration based on the APA, asserting that the new agreement's terms should apply, while Deshmukh contended that the prior agreement should govern. This disagreement led to the case being brought before the Supreme Court of New York County, where the initial ruling favored the law firm.

The Ruling

The Appellate Division of the Supreme Court of New York unanimously affirmed the lower court's decision to compel arbitration. The judges involved in the ruling included Webber, Moulton, Friedman, González, and Chan. The court stated, "When parties clearly express their intention that a subsequent agreement supersedes a prior one, the latter agreement controls." This ruling was based on the clear language of the APA, which specified that all prior agreements were terminated and that any disputes related to the agreement would be resolved through mediation or arbitration.

The court also addressed Deshmukh's argument that the ruling to compel arbitration conflicted with a prior order regarding the sealing of documents. The judges clarified that the sealing decision was based on balancing privacy interests with public rights, rather than strictly on contract interpretation. They concluded that the previous order did not negate the enforceability of the arbitration clause in the APA.

Impact

This ruling has significant implications for how disputes are resolved in legal partnerships. By affirming the enforceability of arbitration clauses in partnership agreements, the court reinforces the idea that parties must adhere to the terms of their agreements, even if those terms change over time. This decision may encourage law firms and other businesses to include clear arbitration provisions in their contracts to avoid lengthy litigation.

The court's ruling also highlights the importance of understanding the implications of signing new agreements that contain different terms from previous contracts. It serves as a reminder for professionals in any field to carefully review the terms of their agreements, especially when they involve dispute resolution mechanisms.

What's Next

Deshmukh may have the option to appeal this decision to a higher court, although details regarding any potential appeal were not available in the court filing. There are currently no related cases pending that were mentioned in the ruling.
