It has taken years to finally get sorted out. The fine stems from an antitrust investigation by the European Commission, the executive arm of the European Union, which concluded in 2017.

The commission said at the time that Google had favoured its own shopping comparison service over those of its rivals.

Google decided its best course was to appeal all the way to the top, and hope that the EU got bored or the case would be thrown out.

However, it did not go that way. Google first appealed the decision with the General Court, the EU’s second-highest court, which also upheld the fine. Google then brought the case before the European Court of Justice, the EU’s top court.

The ECJ on Tuesday dismissed the appeal and upheld the commission’s fine.

Google said that it was disappointed with the decision of the Court.

“This judgment relates to a very specific set of facts. We made changes back in 2017 to comply with the European Commission’s decision. Our approach has worked successfully for more than seven years, generating billions of clicks for more than 800 comparison shopping services.”

To address European concerns, Google in 2017 made changes that meant it will have to bid in the same way as competitors for advertising slots within shopping search results.

The Google decision caps off another major case for the EU after the ECJ also confirmed a European Commission decision from 2016 that Apple should pay 13 billion euros in back taxes in Ireland.
