On Thursday, Google suffered a major setback. Juliane Kokott, the advocate general of the EU’s top court, recommended that the court reject Google’s appeal against a massive €4.12 billion (about $4.7 billion) antitrust fine and uphold the ruling.

“Google held a dominant position in several markets of the Android ecosystem and thus benefited from network effects that enabled it to ensure that users used Google Search,” said Kokott. “As a result, Google obtained access to data that enabled it to improve its service.”

Google responded that it was “disappointed” by the advocate general’s opinion, stating that it “will hinder investment in open platforms and harm Android users, partners, and app developers.” The company argued that Android provides more choices for everyone and supports thousands of successful businesses across Europe and around the world.

While the opinion of the advocate general is not legally binding, EU judges follow such recommendations in about 80% of cases. The European Court of Justice is expected to issue a final ruling in the coming months.

The fine stems from a long-running antitrust case related to Google’s Android operating system. In 2018, the European Commission imposed a record-breaking penalty, citing Google’s abuse of dominance in the smartphone market by securing unfair advantages for its apps through pre-installation deals with device manufacturers.

This penalty is one of three major cases targeting Alphabet, Google’s parent company. Over the past decade, regulators worldwide have levied a total of €8 billion in fines against the tech giant.

According to the Financial Times, this legal win is a major boost for the European Commission, which is pushing for stricter enforcement of new rules to hold the world’s largest tech companies accountable. More antitrust investigations—and hefty penalties—are likely ahead. Some even speculate this may be the EU’s new revenue strategy.
