Google is facing a £7 billion class action lawsuit in the UK after the Competition Appeal Tribunal certified a collective action accusing the tech giant of abusing its dominant position in mobile search. The tribunal dismissed Google’s objections to the claim proceeding, marking one of the most significant antitrust challenges the company has faced on British soil.

The case centers on a straightforward, if painful, allegation: Google used its grip on mobile search to inflate advertising costs, and UK consumers ended up footing the bill every time they bought something through a business that ran Google search ads.

What the lawsuit actually claims

The appointed class representative is Nikki Stopford, with legal advisory firm Hausfeld guiding the action. The claim covers UK consumers aged 16 and above who used Google’s search advertising ecosystem, either directly or indirectly, to purchase goods and services.

The core theory of harm is a classic pass-through argument. Businesses paid inflated prices for Google search ads because Google had monopoly pricing power, and those businesses passed the extra cost onto shoppers in the form of higher prices. The consumers, not the advertisers, absorbed the real damage.
