MADRID (AP) — Google Chairman Eric Schmidt and a panel of experts held the first of seven public sessions Tuesday to help the company define how it should enforce a new “Right to be Forgotten” rule under which Europeans can seek the removal of embarrassing search results.

The company has received more than 120,000 requests to take down 457,000 links since a May court ruling enabled Europeans to ask for the removal of embarrassing personal information that pops up in a search of their names. 

“We need to balance the right to information against the rights of privacy,” Schmidt said before he and other panel members heard testimony from Spanish privacy and right-to-know experts.

While Google says some decisions to remove or deny the removal of search results are relatively easy, the meetings across Europe are being held to help Google determine how to address European cases that fall into gray areas.

They include removal requests by former politicians criticized for their policies, criminals who don’t want their convictions known, bad reviews for architects or teachers and comments people wrote about themselves that they now regret.

Google said Tuesday it could not immediately provide information on how many requests for takedowns have been approved and how many have been denied.
