Google won a legal challenge Wednesday against a €1.49 billion ($1.66 billion) antitrust fine from the European Union, while chipmaker Qualcomm failed to repeal a penalty.

The rulings underscore the mixed record of outgoing EU antitrust chief Margrethe Vestager in defending her crackdown on Big Tech in court. She scored two major wins last week: against Google in a separate case and against Apple’s tax deal with Irish authorities.

In a 2019 decision, the European Commission said Google, owned by Alphabet (GOOGL), had abused its dominance to prevent websites from using brokers other than its AdSense platform that provided search ads. The practices that it said were illegal took place from 2006 to 2016.
