Technology behemoth Google has received demand notices from the Competition Commission of India (CCI) for failing to pay - within the stipulated time - penalties imposed on it for anti-competitive practices, sources told ET on Wednesday. The action came after Google filed appeals last week against the anti-monopoly watchdog's verdict on its Android operating system for smartphones. Sources said since Google had appealed in both cases, the fines become payable only after the court rules on the stay application. They said the demand notices are standard procedure and that there is a 30-day deadline for payment.
