Google faced a big setback Thursday in its attempt to overturn a multibillion-dollar European Union antitrust penalty involving Android after a top court's legal adviser sided with regulators. The European Court of Justice's advocate general, Juliane Kokott, recommended in a non-binding opinion that Google's appeal against the fine worth more than 4 billion euros ($4.7 billion) should be dismissed. The case dates back to 2018, when the EU’s executive Commission slapped Google with a 4.134 billion euro fine after finding that the U.S. tech company used the dominance of its mobile Android operating system to throttle competition and reduce consumer choice.
