Justin Nelson is the go-to lawyer for high-stakes litigation. Justin’s practice centers on taking cases to trial, arguing key motions leading up to trial or the appeal, and positioning the case for victory. He brings an unparalleled combination of trial and appellate excellence. In 2024, he was nominated for Litigator of the Year by the American Lawyer.

Justin represented Dominion Voting Systems in its litigation against Fox, culminating in April 2023 with a $787.5 million settlement—an amount that represented “vindication and accountability,” as Justin stated.

PIONEERING WORK

Justin is one of the foremost leaders and experts in AI litigation. He was selected by the Court to serve as Interim Lead Class Counsel in MDL suits versus OpenAI and Microsoft, In re: Open AI Copyright Infringement Litigation.

Justin is co-lead counsel representing copyright owners against Anthropic, alleging Anthropic committed copyright infringement in its artificial intelligence systems. The case against Anthropic recently settled in “historic” fashion, with a deal for $1.5 billion.

Justin has a number of other cases regarding artificial intelligence, including other copyright matters along with patent litigation. He also is defending Media Matters against X Corp., a case that has received attention based on the implications for the First Amendment and for media organizations. Justin also serves as an American Law Institute panel member on Civil Liability for Artificial Intelligence and speaks regularly on AI-related issues.

Justin’s practice spans across other complex cases as well, from antitrust to bankruptcy to contractual disputes to fraud to patent litigation to trade secret theft.

Among other cases, Justin was lead counsel for Green Mountain when it obtained a $64.5 million judgment against Ardagh in the Federal District Court of Delaware—a verdict upheld on appeal and was included on National Law Journal’s Top 100 Verdicts of the Year list. Justin won a $38 million judgment for repeat client, Fractus, (a case that later settled on appeal) and has led a strategy that has resulted in Fractus recovering over $100 million.

HIGH PROFILE LITIGATION

Dominion v. Fox was one of a number of high-profile cases for Justin. In Dominion v. Fox, the summary judgment briefing in the case earned widespread praise from the legal community and the broader public alike. Justin also represented a number of plaintiffs against a major car rental company that resulted in victories in court and ultimately a settlement.

Justin previously represented various governmental individuals regarding the 2020 election. His clients included entities with both Republican and Democratic control. Among his clients, Justin represented the Arizona Secretary of State in Bowyer v. Ducey and argued the successful motion to dismiss regarding the false allegations of election fraud. Justin also successfully represented the Governor of Wisconsin in a series of litigations related to the 2020 election.

Justin also represented a number of plaintiffs against a major car company that allegedly falsely reported its clients to the police for car theft. That case resulted in a combined nine-figure settlement across the hundreds of plaintiffs who had been injured by the false reports. The artificial intelligence cases and the ERC cases also have generated substantial attention given their intersection of law and policy—an area where Justin often litigates.
