Alphabet unit Google has asked the European Court of Justice to dismiss an appeal by EU antitrust regulators, seeking to finalize a lower court ruling that annulled a €1.49 billion ($1.7 billion) fine.

The tech giant argues that the European Commission’s original penalty was based on flawed reasoning regarding its Android operating system licensing practices.

The case centers on whether Google illegally forced device manufacturers to pre-install its search and browser apps in exchange for access to the Play Store.

A lower court previously ruled that the Commission failed to prove these conditions were anticompetitive, effectively wiping the slate clean for Alphabet on this specific charge.

The Commission, however, has appealed that decision, maintaining that the practices distorted competition in the mobile search market.

This legal battle is part of a broader regulatory crackdown on Big Tech in Europe.
