Rowe, Mercer & Hale LLP secured a significant jurisdictional victory in April 2026 when the Illinois Appellate Court vacated a $22 million arbitration award that had been entered against one of the firm’s private equity clients. The decision, which turned on a threshold question of arbitral jurisdiction, eliminated the entire award and marks a consequential result in a dispute that had originally appeared to present substantial financial exposure.
Background
The underlying dispute arose from a complex investment transaction in which the claimant alleged breaches of representations, warranties, and post-closing covenants. The arbitration panel entered an award of approximately $22 million against the private equity client following proceedings that spanned several years. Rowe, Mercer & Hale was retained after the award issued to assess options for post-award review.
The Jurisdictional Challenge
The firm’s appellate team identified a dispositive threshold issue: the arbitration agreement on which the claimant had relied did not extend to the specific entities named as respondents. Under Illinois law, arbitration is a creature of contract, and a party cannot be compelled to arbitrate—or bound by an arbitration award—absent a valid agreement to do so.
The firm petitioned the circuit court to vacate the award under the Illinois Uniform Arbitration Act, arguing that the panel lacked jurisdiction over the client because it was not a party to the operative arbitration clause. When the circuit court denied that petition, Rowe, Mercer & Hale pursued the matter to the Illinois Appellate Court.
Appellate Court’s Ruling
The Appellate Court agreed with the firm’s position, holding that the arbitration panel exceeded its authority by proceeding against an entity not bound by the arbitration agreement. The court vacated the $22 million award in its entirety. The ruling reaffirms the principle that arbitral jurisdiction must be established as a predicate to enforcement and that courts will not give effect to awards entered without a proper contractual foundation.
Significance
The outcome demonstrates the value of rigorous post-award review, even when an adverse award has already issued. Jurisdictional defects in arbitration proceedings can remain viable grounds for vacatur under both Illinois law and the Federal Arbitration Act, and a thorough analysis of the underlying contractual framework is essential before accepting any arbitration result as final.
