A former clerk for the U.S. Supreme Court, D.C. District, and Northern District of Illinois, Greg Dubinsky has a wide-ranging practice in which prominent clients call upon him to handle high-profile, complex matters across the country requiring the highest level of legal acumen and trial know-how.
To take a few current examples, Greg is lead counsel in high-stakes cases involving constitutional law, data privacy, and contract law. On behalf of former Governor Cuomo, Greg recently argued in New York Supreme Court a separation-of-powers challenge to the Commission on Ethics and Lobbying in Government, which has charged the former Governor with state ethics violations. In a case of great importance to the 2022 mid-term elections and beyond, Greg helped the League of Women Voters, as amicus, secure a historic decision from New York’s highest court invalidating the state legislature’s congressional and state Senate redistricting maps. It was the first time since the 1960s that the New York Court of Appeals had struck down the result of the redistricting process. Its opinion criticized the Democrat-controlled legislature for failing to heed a 2014 state constitutional amendment prohibiting partisan gerrymandering, and found the redistricting maps “procedurally unconstitutional.” The ruling orders the New York Supreme Court to draw new constitutional maps.
Beyond constitutional law, Greg is lead counsel for Rumble Inc., an online media company, in defending a class action under the Video Privacy Protection Act in federal court in Florida. In that ongoing case, the putative class plaintiffs challenge Rumble’s use of the Facebook Pixel and assert statutory damages that could run into the billions. And Greg is co-lead counsel in a case heading to trial in federal court in Arkansas brought by a supplier against Walmart for breach of a $540 million contract. Greg was also a key member of the HSG team representing the petitioner in a high-profile case in the U.S. Supreme Court regarding the territorial scope of RICO.
Greg’s recent victories also speak to his breadth of expertise and ability to handle all manners of high-profile disputes. For instance, when it faced a federal antitrust suit pertaining to the approval of player agents, the National Basketball Association called on Greg to represent it as lead counsel; Greg secured dismissal of the suit in the district court in Ohio and, on appeal, affirmance by the Sixth Circuit. Last year, in a confidential arbitration raising complex securities-law issues, Greg, as lead counsel, secured a favorable settlement for his client. Greg also helped steer the defense of a public company in a securities class action last year, deposing the plaintiffs’ certification expert, resulting in a favorable settlement. Greg also played a major role in the team that tried a $700 million antitrust case in SDNY against Rupert Murdoch’s News Corp. Among other things, Greg drove the plaintiff’s damages case, including deposing News Corp.’s damages expert. In 2021, after a three-week jury trial, with Greg playing a substantial role, the case settled favorably during jury deliberations.
Greg has argued cases in the First, Second, Ninth, and D.C. Circuits, the Connecticut Supreme Court, the New York Supreme Court and Appellate Division, the U.S. District Court for the Southern District of New York, the U.S. District Court for the Northern District of Ohio, and in arbitration. He has also been appointed by the U.S. Courts of Appeals for both the First Circuit and the D.C. Circuit to argue and brief cases raising constitutional questions. Greg has an active pro bono practice, in which recent victories include securing asylum for an Afghan national who served with U.S. forces and was threatened by the Taliban and winning the first-ever successful bail motion for a civil immigration detainee in the Second Circuit.
He was named to the inaugural 2023 Lawdragon 500 X – The Next Generation and Benchmark Litigation’s 40 & Under List (2022), and has been recognized as a Rising Star by the New York Law Journal (2021) and by Super Lawyers (2020-2022).
