Facebook is suing Ireland's top privacy regulator amid a battle over the future of the EU-U.S. Privacy Shield.
Ireland's Data Protection Commission sent a preliminary order to Facebook this week asking the company to stop transferring EU user data to the U.S., claiming Facebook was violating a recent court decision that struck down the privacy shield.
It would be technically difficult for Facebook to silo EU user data. "A lack of safe, secure and legal international data transfers would have damaging consequences for the European economy," Facebook said in a statement. "We urge regulators to adopt a pragmatic and proportionate approach until a sustainable long-term solution can be reached."
