BRUSSELS— Alphabet Inc.’s Google begun its appeal Monday to overturn a $5 billion antitrust fine imposed by the European Union, contending that its Android operating system for mobile devices has boosted competition rather than foreclosing it.
The tech giant presented oral arguments in Luxembourg before the EU’s second-highest court, in its appeal to overturn the 2018 decision from the bloc’s antitrust enforcer. In that case, EU authorities found Google had illegally abused the market power of Android to push companies that manufacture and distribute Android phones into agreements aimed at entrenching and expanding the dominance of the Google search engine on mobile devices.
