A Moscow city court ordered the search engine provider to pay a fine of RUB 50,000 (roughly Rs. 50,650) to a Russian man who sued them for illegally reading his emails, the court's press service told AFP.
Google rejected the court's decision which could open the door for a slew of further cases by insisting that its targeted adverts were handled by an automated system.
"Humans are not reading your emails. Our automated systems scan emails in order prevent spam reaching your inbox and to detect bad things like malware," the search provider told AFP.
"We use the same system to ensure you see advertising that is relevant to you."
The court ruling came after Russia's antitrust authority announced Monday it had found Google guilty of unfairly keeping rival services off mobile devices in a probe demanded by local search engine provider Yandex.
The Federal Antimonopoly Service deemed Google in breach of a law on "protecting competition" after an investigation launched in February following a complaint by Yandex, Russia's largest search engine.
Google could face a fine of up to 15 percent of the income it has made from the sector in Russia over the past year due to the ruling.
