WSJ.com: “European Union privacy watchdogs grilled Google Inc. and other search engines for two hours on Thursday on how they are implementing the bloc’s new “right to be forgotten” online–and then gave them homework to do by next week, too. The main body that joins together the EU’s national data-protection regulators called the Brussels meeting with Google, Microsoft Corp. and Yahoo Inc. amid rising discontent from some regulators over elements of Google’s application of the surprise May court decision that gives Europeans the right to ask for the removal of links from search results for their names in some cases. Regulators  touched on some hot-button issues in six oral questions and another 26 written ones, with answers due by next Thursday. They asked Google to describe the “legal basis” of its decision to notify publishers when it approves right-to-be-forgotten requests, something that has led to requesters’ being publicly identified in some cases. They also asked search engines to explain where they take down the results, after complaints from some regulators that Google does not filter results on google.com. That means that anyone in Europe can switch from, say, google.co.uk to Google.com to see any removed links. In response to another question, Google told regulators Thursday that it has been removing just over 50% of the items that people have asked to be unlinked from searches for their names, while rejecting just over 30% of requests, and asking for more information on 15%.”
