Arun Subramanian
Partner, Pro Bono Chair

Arun is a partner at Susman Godfrey; a member of the firm’s Executive Committee; a former law clerk to three Federal judges, including Justice Ruth Bader Ginsburg; and has been appointed by the Chief Justice of the United States to serve on the Advisory Committee for the Federal Rules of Evidence.

“His intellectual horsepower is rivaled by few. He can take in information, analyze it very quickly and come up with a solution quicker than anyone.”
As quoted in Chambers USA NY Commercial Litigation, 2022

Arun has tried and arbitrated high-stakes cases on both sides of the “v,” and has successfully recovered over a billion dollars for public and private entities who were the victims of fraud and other illegal conduct.  Arun’s expertise isn’t limited to any practice area. He has taken up the cause of public entities and whistleblowers in False Claims Act cases, victims of trafficking in child pornography, consumers and individuals injured by unfair and illegal practices, and has for over a decade focused on complex commercial litigation, including antitrust, patent infringement, and breach of contract cases.

“[Arun is] an ‘agile thinker’ with the ability to ‘master complex problems and distill them to their essence in writing and presentation to the court’”
Assured Guaranty General Counsel and Managing Director, Ed Newman

Arun has been actively involved in a variety of landmark matters for Susman Godfrey. No matter the arena, Arun has a proven track record of success. This includes:

  • Securing over $400 million for state and federal governmental entities in United States ex rel. Kester v. Novartis Pharmaceuticals Corp. Working collaboratively with state and federal enforcement agencies, Arun and his team at SG have recovered over $600 million for the public fisc in the False Claims Act arena.
  • Recovering $590 million in settlements in the ongoing LIBOR price-fixing class action. Susman Godfrey, as co-lead counsel to the OTC plaintiffs, won class certification on behalf of the class and continues to pursue relief against the global banks alleged to have conspired to fix the “LIBOR” financial benchmark.
  • Achieving a complete jury victory in Tyler, Texas as co-lead counsel on behalf of defendant Globus Medical in a spinal insert patent infringement suit brought by Flexuspine, a local Tyler company.
  • Securing a trailblazing judgment victory of over $100 million for client Assured Guaranty against Flagstar Bank in one of the first trials concerning repurchases of faulty RMBS—a significant milestone in forcing banks to honor contractual commitments made which they sought to avoid after the financial crisis.

“He’s able to get right to the heart of the matter quickly. He is super thoughtful and articulate, has an amazing skill set, and is very tough when he has to be”
Client quote in Chambers USA NY Commercial Litigation, 2021

Arun also focuses on briefing and arguing appeals in both state and federal court, including securing important rulings on emotional distress claims under New York law, the validity of inventors’ patents under Section 101 of Patent Act, prisoners’ rights under the Fourth and Eighth Amendments, and unjust enrichment claims arising under New York law.  Most recently, Arun was counsel of record for the respondents before the Supreme Court in Ninth Inning v. NFL, where the Court rejected the NFL and DirecTV’s bid for certiorari, leaving in place the Ninth Circuit’s decision upholding antitrust claims asserted by a nationwide class of “Sunday Ticket” consumers.  You can read Arun’s brief in opposition to the petition for certiorari here.

“He had a really good handle on reading the judges and he also has a very deep understanding of the law.”
Client quote in Chambers USA NY Commercial Litigation, 2018

Outside of the courtroom, Arun contributes to the legal community by taking on pro bono cases and has for years served on the pro bono panel for the United States Court of Appeals for the Second Circuit. Arun serves as Chairperson of  Susman Godfrey’s 2022 Pro Bono Committee and is also a longtime Director of the Columbia Law Review, one of the Nation’s pre-eminent legal journals.  You can read Arun’s recent piece for the Review, honoring the career and legacy of the late Justice Ginsburg, here: “A Titan Among Us: On Dissents, Waymaking, and Strong Coffee.” Arun was recently named a member of the Development Committee for The Appellate Project, an organization that provides opportunities for minority lawyers and law students in the field of appellate law.

“Arun Subramanian is praised by clients for his ‘strategic thinking, legal expertise and client communications.’ He acts for both plaintiffs and defendants in large-scale disputes, including antitrust, breach of contract and healthcare mandates.”

  • United States ex rel. Kester v. Novartis Pharmaceuticals Corp. Working collaboratively with the United States Attorney’s Office for the Southern District of New York and several state attorneys general, secured over $400 million in settlements for state and federal governmental entities in a case alleging Novartis defrauded the Medicare and Medicaid programs by illegally paying kickbacks to pharmacies so that they would recommend Novartis drugs to doctors and patients. The recovery was the largest of its kind for the type of pharmacy kickback scheme involved in the case.
