CONSUMER PROTECTION
In its monumental Buy Box litigation, the firm currently represents consumers suing Amazon for losses suffered as a result of the company’s alleged anticompetitive conduct. Aggregate damages in this case are estimated to be over £2 billion, and the proposed class comprises approximately 51.8 million people, showcasing Hagens Berman EMEA’s dedication to large-scale and complex litigation.
According to the claim, Amazon uses a proprietary algorithm to rank search results whenever a consumer searches for a product in its Marketplace, with the “winning,” first-ranked item typically appearing in the “Buy Box.” Overwhelmingly—about 80% of the time—consumers accept Amazon’s recommendation. The claim alleges that the algorithm steers consumers towards products that are more profitable for Amazon while obscuring other, often more affordable options, thus dampening price and quality competition among sellers and causing consumers to pay artificially inflated rates.
Success in this antitrust matter includes a 2025 ruling from the Competition Appeal Tribunal denying Amazon’s appeal against Hagens Berman EMEA’s client, Mr. Robert Hammond. The Tribunal also certified a class of Amazon customers and unanimously approved Mr. Hammond as the class representative to lead the claim. The firm looks forward to continuing to champion the rights of UK consumers in this ongoing action.
EMISSIONS LITIGATION
United States law firm Hagens Berman is a global litigation pioneer advocating on behalf of consumers who owned or leased diesel vehicles that did not comply with emissions laws. The firm has reached settlements in emissions-cheating matters totaling more than $17.4 billion.
When news broke in 2015 of Volkswagen’s massive diesel emissions-cheating scandal, Hagens Berman represented thousands of consumers and took a leading role on the plaintiffs’ steering committee that would finalize a $14.7 billion, record-breaking settlement for owners. Hagens Berman has uniquely dedicated its resources to uncovering cheating devices used by other automakers as well, and the firm’s work has led the firm to uncover emissions cheating perpetrated by General Motors and Fiat Chrysler prompting multiple U.S. investigations.
Hagens Berman has been on the forefront of this highly specialised realm of law, and Hagens Berman EMEA LLP propels its steadfast and intensive investigative skills to unearth emissions-cheating schemes by automakers and support government regulators in the pursuit of car manufacturers that have violated emissions standards, regulations and UK consumer confidence. This list of offending automakers includes Mercedes.
Hagens Berman’s work and results are further evidenced by Mercedes’ $2.2 billion agreement in principle with the Department of Justice, U.S. Environmental Protection Agency and California Attorney General’s office including a $700 million settlement for U.S. consumers impacted by the loss of resale value and other damages. Hagens Berman is committed to ensuring recovery for all Mercedes owners around the globe and will be helping United Kingdom Mercedes owners receive the justice they deserve.
