Google has accused India's competition watchdog, the Competition Commission of India (CCI), of "copying" elements of an EU ruling.
It follows a decision by the authorities to fine the tech giant US$157mln for using its Android platform to dominate the market, according to a filing to an Indian appeals tribunal seen by Reuters.
The CCI accused Google of entering into "one-sided agreements" with smartphone makers to ensure the dominance of its apps, leading to the fine in October.
Google has claimed that the CCI used "evidence from Europe that was not examined in India" and there were "more than 50 instances of copy-pasting" from the European Commission's ruling.
The CCI has not commented on the allegations.
Google, part of the US stock market-listed tech giant Alphabet Inc (NASDAQ:GOOG), is also facing anti-trust cases in India over its conduct in the smart TV market and its in-app payment system.
