The Moscow Arbitration Court rejected an appeal by Google and upheld a ruling which found the US search giant guilty of “abusing market dominance” with its Android activities.

The case concerned the bundling of Google’s apps and services, to the detriment of other competing products. In order to provide access to Google’s app store, vendors also had to pre-install other Google apps and give them prominent positions.

In a statement, the Federal Antimonopoly Service (FAS) said the arbitration court “fully supported” its decision. After the FAS ruling, the US search giant had said it wanted to “contest this decision and explain in court why we consider it unfounded”.

At the time, Yandex, the Russian search company behind the complaint which started the process, said it was “confident in every point of its position”.

While Yandex has long dominated the Russian search market, it has seen its share slide as usage of mobile devices increased, with Google the beneficiary through the strength of Android.

The company now has to amend its contracts with smartphone manufacturers and pay a fine, according to Reuters.

Back in October, EU competition chief Margrethe Vestager said an investigation opened up in April by the European Commission into Google’s Android mobile operating system is “high priority” for EU regulators.

The probe also deals with applications and services for smartphones and tablets breaching EU antitrust rules.

In November, the Application Developers Alliance called on the EC to consider whether its investigation of the Android platform “could harm thousands of developers who write on the platform”.
