A major data-sharing deal between the EU and US is ‘invalid’ given the spying revelations in the Edward Snowden scandal, the top EU court’s main legal advisor said Wednesday in a case brought against Facebook. The case stems from a complaint against Internet giant Facebook lodged at Ireland’s data protection authority by Austrian law student and right-to-privacy activist, Max Schrems. The complaint focused on a landmark deal reached by the European Commission with Washington 15 years ago that allows thousands of businesses operating in the EU to send the private data of Europeans to servers in the US.
