According to a Reuters report on Saturday quoting court documents, Google has officially appealed a decision by the nation’s antitrust regulator against the company’s Android platform.

Google, a division of Alphabet Inc (GOOGL.O) was fined 13.38 billion Indian rupees ($161.95 million) by the Competition Commission of India (CCI) for alleged anticompetitive practices it engaged in with respect to the company’s Android operating system. The CCI ruled that Google abused Android’s smartphone dominance by requiring the company’s entire Google Mobile Suite be installed by smartphone makers.

The US company appealed the decision to a appeals tribunal, noting it would harm its business model and consumer’s interests, if it were forced to adjust its practices in the matter. Earlier this week the tribunal ruled, refusing to block the anti-trust regulator’s decision.

The Reuter’s report noted that the records from the Supreme Court noted Google had filed an appeal with the court over the tribunal’s ruling on Saturday, however no hearing date has yet been set.

According to sources quoted by the news outlet, the company believes the Supreme Court Appeal will be its final chance to block the CCI decision, which goes into force on January 19th.

By volume, India is the largest market of users for Google. The Android operating system powers 97% of the nations’ smartphones, and the Google Pay app, the company’s online payment platform, the the most popular payment app among smartphone users.
