MOSCOW, February 15 (RIA Novosti) - Russian consumer rights watchdog Rospotrebnadzor is studying YouTube’s lawsuit against it, the watchdog’s head, Russia’s chief state sanitary doctor Gennady Onishchenko, said Thursday.

“We only saw today that the lawsuit has been registered,” Onishchenko told the Dozhd TV channel. “We are studying it.”

YouTube LLC on Tuesday filed a lawsuit against Rospotrebnadzor over a controversial Russian content-restricting law, internet company Google’s video sharing unit said.

The law on protection of children from harmful information that came into force late last year authorizes regulators to block access to data deemed “harmful to the health and development” of children through promotion of suicide, porn and drugs.

Critics claim the law might be used as an internet censorship means, but the authorities dismiss the claims.

The lawsuit, filed in a Moscow court Monday, is against Rospotrebnadzor’s decision to block access to a “video lesson on how to cut veins.”

The Wall Street Journal on Tuesday quoted Google as saying in an emailed statement: “In this case, we have appealed the decision of the Russian consumer watchdog because we do not believe that the goal of the law was to limit access to videos that are clearly intended to entertain viewers.”

YouTube was briefly put on a blacklist of websites with harmful content (zapret-info.gov.ru) in November 2012. Failure to remove what media and communications watchdog Roskomnadzor said were “suicide promotion” materials would have led to YouTube’s blocking across Russia.
