Google has filed an appeal with the Court of Justice of the European Union (CJEU) against the 4.125 billion euro fine imposed by the European Commission for abuse of a dominant position in the Android case, the American giant revealed today.

"There are areas that require legal clarification from the European Court of Justice," said the technology company about the case in which it was accused by Brussels of restricting mobile competition and consumer choice through the Android operating system, and is now taking the case to the European Union's (EU) highest court.

In September, the EU's General Court partially upheld a first appeal by Google, reducing the original fine - imposed in July 2018 - from 4.34 billion euros to 4.1 billion, in what remains the largest fine for anti-competitive practices imposed by the Commission.

"Android has created more choice for everyone, not less, and supports thousands of successful companies in Europe and around the world," defended the company quoted by Lusa, in the face of accusations that it had applied illegal restrictions to device manufacturers using its Android system, in order to strengthen its dominant position.

In its 2018 ruling, Brussels concluded that Google's Android dominance has resulted in less competition and consumer choice. The US tech giant had argued that free, open-source Android resulted in cheaper phones and stimulated competition with its main rival, Apple.

The fine was one of three penalties for anti-competitive practices that the Commission imposed on Google between 2017 and 2019, highlighting the European bloc's early role in combating the tech giants.

Google is also appealing to the CJEU - which only rules on questions of law - against its first penalty for infringing EU competition rules, to the tune of 2.4 billion euros, for allegedly unfairly favoring its Google Shopping comparison service.

Finally, the American giant is still appealing to the EU's lower court against a third fine of 1.49 billion euros for abusing its dominant position in online search ads.
