Google has rejected a French demand to globally apply the so-called right to be forgotten, which requires the company to remove links to certain information about users if asked.
"While the right to be forgotten may now be the law in Europe, it is not the law globally," Google's global privacy counsel Peter Fleischer said in a blog post yesterday.
The statement was a response to a demand by France's national data protection authority, CNIL, to globally implement a May 2014 ruling of the European Court of Justice that allows people to ask search engines to de-list links with personal information about them.
The ruling applies when the online information is deemed "inaccurate, inadequate, irrelevant or excessive".
In its post, Google branded the French request "a troubling development that risks serious chilling effects on the web."
"If the CNIL's proposed approach were to be embraced as the standard for Internet regulation, we would find ourselves in a race to the bottom. In the end, the Internet would only be as free as the world's least free place," it added.
Google said it had evaluated and processed more than a quarter of a million requests to de-list links to more than a million web pages since the European Court of Justice's ruling.
Following several hundred requests from French users, CNIL told Google in June it should apply the ruling globally and remove links from the whole of its network -- not just from google.fr and other European sites.
"As a matter of principle... we respectfully disagree with the CNIL's assertion of global authority on this issue and we have asked the CNIL to withdraw its Formal Notice," Google said.
Google has become a lightening rod for critics in Europe on a broad range of issues from privacy to the protection of national publishers.
The Wikipedia information website has described the European ruling as creating "memory holes" in the Internet, while critics of the US Internet giant have said such standards are necessary to protect the privacy of citizens.
