United States joins case over Facebook data transfers from EU

The United States can join a landmark case on the legality of cross-border data transfers, an Irish court ruled on Tuesday in a move that gives U.S. authorities a platform to defend their surveillance laws before the European Union's top court. The U.S. authorities had asked the Irish High Court to be a party to the case taken by Austrian privacy activist Max Schrems against Facebook, which has its European headquarters in Dublin, over data transfers from the EU to the United States.
