In May, the European Union's highest court ordered Google to grant EU citizens a "right to be forgotten" that would allow them to remove "inadequate" or "irrelevant" links. Google complied, providing a new form that was used thousands of times—mostly by those seeking to erase links related to accusations of fraud and other serious crimes.

But Google only removed links on its European sites, like google.co.uk. Users in Europe, or anywhere else, can still get "full" search results by visiting the US version of the site at google.com.

That decision is now under fire by EU regulators and experts, who have said the limitation "effectively defeats the purpose of the ruling," according to a Reuters report. EU authorities are scheduled to meet with Google today, as well as representatives from Yahoo and Microsoft, to discuss the issue.

The text of the European Court of Justice's ruling doesn't say anything about how to handle requests across varying national sites. If a link meets the criteria, the court ruling simply states that "the links and information in the list of results must be erased." It doesn't detail how and where such deletions should occur.

The idea of stretching the ruling to apply worldwide is a worst-case scenario not just for Google but for critics of the law, who have called it a form of censorship.

"In a sign of the importance Google is attaching to the privacy debate in Europe, it has recruited a panel of high profile academics, policymakers, and civil society experts to advise it on how to implement the ruling as it ploughs through the over 70,000 requests it has received so far," notes Reuters.

Some users who had their requests denied by Google are appealing to state privacy authorities to force Google to remove their links. The British government has received 23 such complaints so far, while French and Italian privacy authorities have received a handful each.

Microsoft just started taking "right to be forgotten" requests for its Bing search engine last week. It uses a four-part Web form that asks for more information than Google's form.
