When a class action threatens operations, reputation, and long-term enterprise value, clients need counsel with the scale, sophistication, and jurisdictional depth to respond decisively.
Our Class-Action Defense practice brings together some of the world's most experienced teams—litigating dozens of class actions annually across multiple continents in proceedings ranging from putative classes by similarly situated claimants to opt-outs bringing collective actions. We combine granular knowledge of local procedural regimes with a unified global strategy, enabling us to manage coordinated multijurisdictional exposure, defeat or narrow claims at the earliest opportunity, and partner with clients to implement post-resolution measures that reduce future risk.
Geographic reach
Our class-action defense capability spans the world's most active collective litigation markets, providing clients with a single coordinating team regardless of where claims arise.
United States
We defend and defeat class actions in both state and federal courts across the country, with particular depth in jurisdictions where class-action filings dominate dockets, including California, where consumer class-action suits are common, and the major federal circuits. Our national practice draws on lawyers firmwide, providing the flexibility and capacity to assemble litigation teams at speed when multidistrict proceedings demand it. We litigate appeals across federal circuits and the highest state appellate courts.
England and Wales
London is now one of the most significant jurisdictions for collective proceedings globally. We are at the forefront of defending claims in this rapidly evolving market. We handle matters across the full spectrum of English procedural mechanisms—Group Litigation Orders (GLOs), bespoke case management directions and test cases, representative actions, and Collective Proceedings Orders (CPOs) in the Competition Appeal Tribunal. We have deep familiarity with the strategic advantages and vulnerabilities each regime presents for defendants, from managing adverse publicity associated with GLO registration to challenging CPO certification on suitability grounds following the Supreme Court's guidance in Merricks v Mastercard.
Australia
We are ranked Tier 1 for class actions in Australia—and have acted in many of the largest, most complex, and highest-profile class actions in Australian legal history. Our experience comprises proceedings in the Federal Court of Australia and state supreme courts, including landmark first-of-their-kind matters: the first shareholder class action determined on market-based causation, the first underpayment class action to proceed to trial, and the successful High Court case on common fund orders.
Europe and Asia-Pacific
Antitrust (competition) class actions are growing across Europe, particularly follow-on damages claims arising from European Commission infringement decisions. As a result, defendants increasingly face coordinated exposure across multiple European jurisdictions simultaneously. We advise on multijurisdictional strategies that account for the interplay between regulatory outcomes in one forum and private damages actions in another. In the Asia-Pacific region, we draw on established litigation capability and market knowledge to defend clients across the region's expanding class-action and representative proceedings regimes.
Industry sectors
Class actions cut across every sector of the economy. Our teams bring not only procedural experience but also industry-specific knowledge that enables us to anticipate litigation trends, understand the commercial pressures our clients face, and craft defense strategies attuned to sectoral dynamics.
Financial services and capital markets
We have extensive experience defending shareholder class actions, securities fraud allegations, and derivative claims arising from mergers, adverse business events, IPOs, and government investigations. We also defend investor class actions arising from structured products, CDOs, and securitized loan portfolios. Our firm represents financial institutions and other clients in the most sophisticated and high-profile class actions across the globe, including groundbreaking class actions targeting financial products, such as those alleging manipulation of critical financial benchmarks, including LIBOR, EURIBOR, and foreign exchange rates, as well as the Bank Fee Class Action for ANZ, described as the largest consumer litigation in Australian history.
Technology and digital economy
We serve as trusted defense counsel to the world's most innovative technology companies, particularly in matters involving innovation deployment and protection, monopolization, vertical restraints, data privacy, AI, biometric information, and digital platform liability. All major technology companies currently face significant risk of competition class actions in the United States, United Kingdom, and Europe, and our class-action team brings extensive experience to defend and defeat high-value claims.
Consumer products, food, and retail
Our consumer products litigation team has decades of experience defending food, beverage, dietary supplement, and consumer goods companies against class actions across multiple jurisdictions. We are recognized as one of the most experienced practice groups in this field and handle claims under unfair competition and consumer protection laws in numerous jurisdictions.
Energy, resources, and ESG
The rise of ESG-related class actions—encompassing climate change, emissions, human rights, environmental disasters, waste disposal, and supply chain accountability—represents one of the most dynamic areas of collective litigation globally. We defend claims that seek to impose parent company liability for the actions of subsidiaries in other jurisdictions, greenwashing allegations, and novel supply chain duty-of-care claims.
Automotive and manufacturing
We defend manufacturers, distributors, and retailers in product liability class actions involving claims worth hundreds of millions of dollars, including mass-recall litigation such as the Takata airbag proceedings.
Communications, fintech, and digital assets
Our work spans telecommunications litigation, fintech and payments disputes, blockchain and digital asset claims, and class actions arising from online platforms and digital services.
Professional services
We regularly defend auditing firms, ratings agencies, and other professional services providers in class actions alleging negligent misstatement, fraud, and breach of duty, including landmark proceedings against KPMG, Deloitte, and S&P Global.
