Google lost its final legal challenge on Tuesday against a European Union penalty for giving its own shopping recommendations an illegal advantage over rivals in search results, ending a long-running antitrust case that came with a whopping fine.

The European Union’s Court of Justice upheld a lower court’s decision, rejecting the company’s appeal against the $2.7 billion penalty from the European Commission, the 27-nation bloc’s top antitrust enforcer.

"By today’s judgment, the Court of Justice dismisses the appeal and thus upholds the judgment of the General Court," the court said in a press release summarizing its decision.

The commission's punished the Silicon Valley giant in 2017 for unfairly directing visitors to its own Google Shopping service to the detriment of competitors. It was one of three multibillion-dollar fines that the commission imposed on Google in the previous decade as Brussels started ramping up its crackdown on the tech industry.

“We are disappointed with the decision of the Court, which relates to a very specific set of facts,” Google said in a brief statement.

The company said it made changes in 2017 to comply with the commission’s decision requiring it to treat competitors equally. It started holding auctions for shopping search listings that it would bid for alongside other comparison shopping services.

“Our approach has worked successfully for more than seven years, generating billions of clicks for more than 800 comparison shopping services,” Google said.

At the same time, the company appealed the decision to the courts. But the EU General Court, the tribunal's lower section, rejected its challenge in 2021 and the Court of Justice’s adviser later recommended rejecting the appeal.

European consumer group BEUC hailed the court's decision, saying it shows how the bloc's competition law “remains highly relevant" in digital markets.

"Google harmed millions of European consumers by ensuring that rival comparison shopping services were virtually invisible," director general Agustín Reyna said. “Google’s illegal practices prevented consumers from accessing potentially cheaper prices and useful product information from rival comparison shopping services on all sorts of products, from clothes to washing machines.”
