The EU's top court will decide Thursday whether to uphold a record 4.1 billion euro ($4.7 billion) fine the bloc slapped on Google for anti-competitive practices related to its Android operating system.
It is the second attempt by the US tech giant to overturn the penalty imposed by the European Commission in 2018 -- which remains the bloc's highest ever antitrust fine, said AFP.
The commission, the EU's antitrust regulator, had accused Google of abusing the popularity of its Android operating system to restrict competition.
It alleged Google pressured phone makers using Android to pre-install its search engine and Google Chrome browser -- essentially shutting out rivals -- and ordered it to pay a 4.3-billion-euro fine.
The findings were upheld in 2022 by the General Court, the EU's second-highest. But the Luxembourg-based body slightly reduced the levy to 4.1 billion euros -- still the EU's biggest ever.
Google filed a new challenge arguing before the bloc's top court, the European Court of Justice, that the case was unfounded and that the sanction penalized innovation.
In first instance, the firm had pushed the case that the EU was unfairly blind to practices by Apple, which gives preference to its own services, such as Safari on iPhones.
It also argued that customers were in no way forced to use its products on Android and that downloading competing apps was just a tap away.
But it suffered a legal blow in June last year when the EU top court's adviser recommended upholding the fine in an opinion, describing Google's arguments as "ineffective".
- Legal battles -
Although not binding, such advice carries weight and is often followed by EU judges in their rulings.
The case is one in a series pitting Google against Brussels.
As part of a major push to target big tech abuses, the EU slapped the Mountain View company with fines worth a total of 8.2 billion euros between 2017 and 2019 over antitrust violations.
This set off a series of long-running legal battles.
Brussels has since armed itself with a more powerful legal weapon known as the Digital Markets Act (DMA), to rein in tech giants.
Rather than regulators discovering antitrust violations after probes lasting many years, the DMA gives businesses a list of what they can and cannot do online.
Google is already the subject of several formal DMA probes, and was hit with a massive 2.95 billion euro fine in September in another competition case predating the digital law for favoring its own advertising services.
That drew an angry rebuke from US President Donald Trump who has accused Brussels of unfairly targeting American firms, and repeatedly threatened to impose retaliatory tariffs on EU exports.
