ACSO has applied for a collective proceedings order to authorise it to bring a collective action against Amazon on behalf of more than 45 million consumers who purchased products from the online retailer between August 2019 and August 2025.
ACSO’s allegation is that consumers making purchases through third-party sellers paid more than they should have because of Amazon's price-parity policies and could therefore be due compensation for the losses suffered. ACSO has instructed the leading international law firm Stephenson Harwood for the proposed proceedings, as well as Ben Lask KC, Luke Kelly and Jenn Lawrence of Monckton Chambers and also The Brattle Group.
More details about the action, including the press release, can be found at amazon costs more.co.uk, but as the proposed class representative ACSO has filed an application for a collective proceedings order with the Competition Appeal Tribunal. Following a hearing, it will decide whether the claim can proceed and on ACSO’s suitability as class representative.
Collective actions such as these provide an important way for consumers to gain access to justice and or examples of poor corporate behaviour to be challenged. If ACSO is successful in its application, acting as a class representative fits with its wider aims as an organisation to support the interests of consumers in the UK's civil justice systems, in this case in seeking fair redress for their losses.
