In a major legal setback for Google, the European Court of Justice has dismissed the company's appeal against a multi-billion dollar antitrust fine. The ruling upholds a decision by the European Commission, which found that Google abused its search engine dominance by favoring its own comparison shopping service over competitors. The decision marks the conclusion of a long-running legal battle that began over a decade ago.

The court's ruling confirms the EU’s authority to impose large penalties on big tech firms for anti-competitive behaviors. Google has expressed disappointment with the decision, stating that it has already modified its search practices to comply with the EU's requirements. The ruling is expected to set a precedent for ongoing antitrust investigations into Google's advertising technology and app store business models.
