Google, which is facing antitrust investigation in India by fair trade watchdog CCI, can face a penalty of up to about five billion dollars if it is found to have violated competition norms of the country.

Google said it is "extending full cooperation" to the CCI in its investigation. The conclusion of a two-year review by the US antitrust watchdog has concluded that the company's services were good for competition, it added. The case has been before the Competition Commission of India (CCI) as well for over two years now and it relates to allegations that Google is abusing its dominant position in the internet search engine space.

Under competition regulations, an entity found violating the norms could be slapped with penalty of up to 10% of its three-year annual average turnover. In the case of Google, its annual revenues in the last three years amounts to a staggering $49.3 billion and the maximum penalty can be up to nearly $5 billion. When asked about the ongoing probe and the potential penalty of up to five billion dollars, a Google spokesperson told : "We are extending full co-operation to the Competition Commission of India in their investigation." "We're pleased that the conclusion of the Federal Trade Commission's two year review was that Google's services are good for users and good for competition," he said in an e-mailed statement.

While Google has settled anti-trust cases in the US and European Union, Indian competition regime does not have provisions for settlement process. Besides a complaint filed with CCI cannot be withdrawn. Finding prima facie evidence of violations, CCI had referred the matter to its investigation arm -- Director General (DG) -- for a detailed probe.

Sources said that the DG has also collected comments from third-parties with regard to this case and it is likely to soon submit its report to

CCI. The Director General could not be contacted for comments. Apart from penalty, CCI is empowered to pass orders to correct a company's conduct in the market place. Also, the regulator can go for structural remedies that could see breaking up of dominant enterprises into separate businesses.

The complaint against Google, also one of the world's most valued company, was first filed by advocacy group CUTS International way back in late 2011. Later, matrimonial website matrimony.com also filed a complaint. Referring to Google's settlement with the European Commission, matrimony.com counsel Ferida Satarawala said: "Google's unfair use of trademarks as well as its retaliatory conduct are not specifically addressed in the European settlement and are distinct theories of harm being pursued by the CCI. Therefore, this settlement is unlikely to address CCI's concerns in our case".
