The European Court of Justice has drawn the curtain on an 8-year legal battle, rejecting Google’s final appeal and upholding a record fine of €4.125 billion ($4.7 billion) for antitrust practices.

The court found that Google abused its dominance of the Android operating system to force phone manufacturers to preinstall its search engine and Chrome browser, and to block competing systems.

Judges rejected Google’s arguments that the system supports innovation, emphasizing that the preinstallation of applications unfairly deprived competitors of access to consumers.

The ruling is final and cannot be appealed. Under it, Google must pay the fine, giving the European Union a significant legal victory in enforcing its new Digital Markets Act against the monopolies of big tech companies.
