£300m Showdown: UK Tribunal Green-Lights Apple-Amazon Reseller Claim - and Every Marketplace Seller Should Pay Attention

The ruling in plain English

On 28 September, a three-judge Competition Appeal Tribunal panel certified part of a revived collective consumer claim against Apple and Amazon. The core allegation: the two companies struck a deal in 2018 limiting which third-party sellers could list Apple and Beats-branded products on Amazon's UK marketplace, reducing competition and inflating the prices shoppers paid.

Judge Kelyn Bacon found the Amazon-marketplace claims to be "plausible, credible and grounded in the facts." The surviving portion of the case is valued by the claimant at between £289 million and £306 million including interest. That is real money; for context, it is roughly the annual revenue of a mid-tier UK fashion retailer.

The tribunal did not hand claimants a blank cheque. A broader theory, that the restrictions also inflated prices at Apple's own stores and at third-party retailers, was thrown out as resting on a "complex and speculative theory of harm." This is a narrower, tighter case than the one originally filed, which matters for how long and costly the road ahead will be.

Third time lucky for the claimants

This case has had more false starts than a 100m final. An earlier version led by consumer law academic Christine Riefa was refused certification in January 2025, not because the competition allegations were disproved, but because of concerns about the proposed representation and funding arrangements. The parallel US lawsuit was killed in September 2025. Now the UK claim has been refiled by JLP A&A Class Representative Limited, led by Justin Le Patourel, who has prior form steering collective proceedings through the CAT.

Apple's defence is that the 2018 agreement was designed to tackle counterfeit goods, not to squeeze out legitimate resellers. Amazon says the remaining claim is without merit. Neither denial is surprising, and neither settles anything. The case now moves toward a full trial on the merits.

What it means for marketplace sellers

Here is the part that does not get enough column inches. This is not just a consumer story; it is a structural question about how dominant platforms are allowed to curate their seller bases. If the claimants eventually win, the implicit argument is that removing resellers, even under the banner of anti-counterfeiting, can constitute an unlawful restriction of competition where it has the downstream effect of inflating consumer prices.

That argument has legs well beyond Apple and Amazon. Any brand that has worked with a major marketplace to restrict who can sell its products should be watching. Selective distribution arrangements, where a brand controls its authorised dealer list, are common in consumer electronics, beauty, luxury goods and sportswear. The CAT's willingness to let this proceed signals that UK competition law is prepared to scrutinise the effects on rival sellers, not just the stated commercial rationale.

For the roughly 281,000 active UK sellers estimated to operate on Amazon.co.uk, this ruling validates that the CAT takes marketplace pricing dynamics seriously. Those sellers already face a fee structure where, from April 2026, Amazon added a 1.5% fuel and logistics surcharge on top of existing FBA fulfilment fees. Margin pressure is not theoretical.

The trademark angle

Brands caught in the selective-distribution crossfire often respond by tightening IP controls. A trademark registration is the legal scaffold that lets a brand police who sells, and how, across marketplace channels. AIBD analysis of IPO (TMD) data shows 5,622 Class 25 UK trademark filings in Q3 2026 alone, up 6.5% on the prior period. Class 25 covers clothing and footwear, but the broader pattern holds across consumer goods: brand owners are filing more aggressively, in part because IP rights give them a defensible basis to manage distribution that pure contractual restrictions may not.

SIC 47.91 (mail-order and internet retail) businesses are among the most active trademark applicants. Many have no registered mark at all when they start selling on Amazon, leaving them exposed both to counterfeiters and to the kind of legal uncertainty this case exemplifies.

The long game

Collective proceedings at the CAT are not quick. The Buy Box claim against Amazon alone, a separate £900 million action filed by Hausfeld in 2022, is still grinding through the system. Le Patourel's Apple-Amazon case, now certified in its slimmer form, could take years to reach a final determination.

This is not the week Apple or Amazon panics. It is the week UK marketplace law became a little less friendly to closed-shop distribution deals. For any DTC brand or third-party seller wondering whether the platform rules they operate under are legally bulletproof, the honest answer just got considerably more complicated.
