Gupta Wessler PLLC

Founded in 2012 with a distinctive mission, Gupta Wessler LLP is the nation’s premier plaintiff-side appellate boutique. With offices in Washington, D.C., San Francisco, and Boston, the firm serves as the go-to appellate partner for trial lawyers nationwide, providing a powerful counterweight to the corporate dominance of the Supreme Court and appellate bar.

Gupta Wessler handles high-stakes matters in the U.S. Supreme Court and appellate courts across the country. The firm approaches every case with a fresh perspective, a strategic sense of how to frame the issues for success, and a singular focus on representing plaintiffs--never corporations. Its clients and collaborators include classes of consumers and workers, public-interest organizations, and trial lawyers seeking to protect their most significant victories.

The firm's docket spans the full spectrum of plaintiff-side practice, including antitrust, consumer protection, civil rights, class actions, workers' rights, products liability, securities fraud, torts (including mass torts), sexual assault, environmental justice, insurance bad faith, intellectual property, and administrative law and constitutional issues of all stripes.

Supreme Court Advocacy for Plaintiffs

Gupta Wessler is unmatched in plaintiff-side advocacy before the U.S. Supreme Court. Among the small group of firms that have appeared most frequently before the Court over the past two terms, Gupta Wessler has the highest win rate, defeating the nation’s top corporate defense firms before the most conservative Supreme Court in generations. All four partners have argued multiple times before the Court, and the firm's lawyers have argued more than twenty merits cases overall.

Landmark victories include class actions, preemption cases, forced arbitration challenges, securities fraud suits, and workers’ rights matters.

• In the Court’s 2024–2025 term, the firm argued four cases, winning three and securing the rare dismissal of two cases after oral argument. These cases include Labcorp v. Davis , on class actions and standing, and Nvidia v. Ohman , on pleading standards for securities fraud.
• In the 2023–2024 term, Gupta Wessler argued three cases and scored two unanimous 9-0 victories for plaintiffs: Cantero v. Bank of America , defeating sweeping federal preemption of state consumer law, and Bissonnette v. LePage Bakeries , defeating forced arbitration of workers’ wage claims.
• In 2021, the firm argued and won a landmark victory for access to justice in Ford Motor Co. v. Montana Eighth Judicial District, in which the Court ruled that people injured by mass-market products can establish personal jurisdiction to sue corporations where their injury occurred, bucking a decades-long trend of jurisdiction-limiting jurisprudence.

Protecting Billions in Landmark Verdicts

When the largest jury awards in America face an appeal, trial lawyers turn to Gupta Wessler.

The firm has successfully defended billions of dollars in verdicts and settlements, safeguarding landmark wins such as:

• A $200 million insurance bad-faith verdict in Nevada, upheld on appeal in the state supreme court and resolved after the insurer filed a petition in the U.S. Supreme Court, representing the largest verdict ever upheld in the state.
• A $1.2 billion consumer class-action settlement with Bank of America, upheld through both the Ninth Circuit and the Supreme Court.
• A $61 million consumer class-action robocall verdict, successfully defended through the Fourth Circuit and a Supreme Court petition.
• A $50 million PFAS exposure verdict, defended through the Sixth Circuit and Supreme Court, resulting in a rare precedent on collateral estoppel in MDL bellwether trials.
• A $20 million prison sexual-assault verdict in Missouri, successfully defended on appeal.
• The firm is currently defending several nine-figure and eight-figure verdicts on appeal, and $1.6 Billion worth of verdicts against Monsanto (over toxic chemical exposure) in the Washington Supreme Court.

No other appellate firm matches Gupta Wessler’s record of protecting transformative jury verdicts nationally. In addition, the nation’s top trial lawyers consistently entrust Gupta Wessler to handle the highest stakes appeals in class actions and MDLs, in state and federal appellate courts, and the firm serves as outside counsel to the American Association for Justice.

The Plaintiffs' Solicitor General--leveling the playing field on appeal, one case at a time

Gupta Wessler was built to serve as a kind of Solicitor General’s Office for the plaintiffs’ bar—and after more than a decade, that’s exactly what it has become. The firm’s collaborative, plaintiff-only practice ensures trial lawyers have trusted partners on appeal in state and federal courts nationwide, with no conflicts of interest and no divided loyalties.

Teaching the Next Generation

Gupta Wessler is committed to training the next generation of advocates. The firm teaches Harvard Law School’s Supreme Court Litigation Clinic and mentors the next generation through its distinctive fellowship and summer programs. The firm views this training and mentoring as an essential part of its mission and is proud of its alumni, who have gone on to clerkships and careers in public interest law, legal academia, and all levels of local, state, and federal government.
