A recent ruling from the District Court for the District of Columbia has dismissed a petition from attorney Joshua M. Ambush and his law firm, Joshua M. Ambush, LLC, to vacate an arbitral judgment in favor of former client Elvis J. Rusnak. This decision, issued by Judge Colleen Kollar-Kotelly on July 23, 2026, is significant as it underscores the importance of filing legal actions in the appropriate jurisdiction and adhering to procedural rules.
The ruling affects Ambush, who sought to challenge the arbitral award after his former client, Rusnak, had already filed a petition to confirm the award in a Maryland court. The court's decision to dismiss Ambush's petition highlights the complexities of legal representation and the consequences of failing to follow proper legal protocols.
Background
The case involves two parties: Joshua M. Ambush, a Maryland resident and attorney, and Elvis J. Rusnak, a New Jersey resident. In 2017, Ambush and Rusnak entered into an Attorney Representation Agreement, under which Ambush provided legal services related to a claim against the Islamic Republic of Iran for a terrorist attack that injured Rusnak in 1996. In 2019, Rusnak was awarded a default judgment of $7 million against Iran.
In 2020, Rusnak received a partial payment from the U.S. Victims of State Sponsored Terrorism Fund, and Ambush received a contingency fee from that payment. However, by the end of 2024, Rusnak terminated Ambush's representation. Ambush then initiated arbitration proceedings in January 2025, claiming Rusnak breached their agreement by failing to pay contingency fees. In February 2026, the arbitration awarded Rusnak damages and found that Ambush had breached the standard of care.
The Ruling
On April 14, 2026, Ambush filed a Petition to Vacate the arbitral award in the District Court for the District of Columbia. Shortly after, Rusnak moved to dismiss Ambush's petition, arguing that it should be dismissed under the “first-to-file rule.” This rule states that when two cases involving the same parties and issues are filed in different courts, the one filed first should proceed.
The court ruled in favor of Rusnak, stating, "The present action and the action initiated by Rusnak in the District of Maryland are parts of a single controversy." The court noted that both actions involved the same parties and the same arbitral award, with the only difference being that Ambush sought to vacate the award while Rusnak sought to confirm it. Judge Kollar-Kotelly emphasized that the dispute should be resolved in the same forum to avoid duplicative litigation.
Impact
This ruling has significant implications for legal proceedings in similar cases. It reinforces the importance of the first-to-file rule, which aims to prevent redundant litigation and promote judicial efficiency. The court's decision to dismiss Ambush's petition without prejudice means that he may still pursue his claims in the appropriate jurisdiction, which is now the District of Maryland.
Moreover, the ruling highlights the necessity for attorneys to be vigilant about the timing and location of their legal filings. By failing to file in the correct jurisdiction first, Ambush lost the opportunity to challenge the arbitral award in the District of Columbia, as the Maryland court is now the primary venue for resolving the dispute.
What's Next
Ambush's case can still be pursued in the District of Maryland, where Rusnak's petition to confirm the arbitral award is already pending. The dismissal of Ambush's petition does not prevent him from continuing his legal efforts in that jurisdiction. Details about any further developments in the Maryland case were not available in the court filing.
