An Order of the Coif graduate of the University of Chicago Law School, Daniel Sullivan clerked for the late Justice Antonin Scalia and, before that, for Judge Diarmuid F. O’Scannlain on the Ninth Circuit. He was recognized as a New York Law Journal Rising Star in 2015, has been named to Benchmark Litigation’s Under 40 Hot List since 2017, and was named to the New York Law Journal’s inaugural Trailblazer list in 2019.
At Holwell Shuster & Goldberg, Dan’s practice focuses on complex commercial litigation and appeals, and transnational litigation. As a leader of HSG’s appellate practice, he recently obtained a reversal of a jury verdict in New York’s First Department in an appeal establishing an important precedent in asbestos cases; a reversal in the First Department in an opinion holding, on a novel legal question, that $140 million in SEC disgorgement is not insurable as a penalty; and a reversal in the Federal Circuit of a jury trial judgment in a patent-infringement case against an auto-parts manufacturer. Dan is currently representing a defendant in the Second Circuit in a high-profile insider-trading appeal. In a matter Dan handled in his individual capacity, he represented Senator Ted Cruz in ballot eligibility challenges in New York State and federal court at the trial and appellate level in connection with the 2016 Republican Presidential Primary election. Dan also appeared on behalf of Governor Andrew Cuomo in litigation challenging, on separation-of-powers grounds, a New York state commission on prosecutorial conduct. The plaintiffs ultimately agreed to drop Gov. Cuomo from the case.
Simultaneously, he has a leading role in a series of massive RMBS putback cases covering billions of dollars in loans. His trial practice also includes securities fraud matters, patent infringement, and other business litigation, including a recent victory obtaining dismissal of breach-of-fiduciary claims against former directors of a technology servicers company in bankruptcy court in the District of Delaware.
Dan is also an active member of HSG’s pro bono practice. He recently represented a legal permanent resident under an order of removal in a Ninth Circuit appeal raising novel issues of the retroactive application of statutes, and a legal permanent resident facing such an order in an Eleventh Circuit appeal raising whether immigration authorities must defer to state-court sentence clarifications. In both appeals, after Dan filed his opening brief, the government agreed to a favorable remand.
