As Google this week will dispute an order to expand the EU’s ‘right to be forgotten’ globally, national internet laws are increasingly stretching across borders.

Google on Tuesday will appeal an order to extend the European Union’s “right to be forgotten” to its search engines across the globe, arguing before the EU’s top court that the order encourages countries to assert sovereignty beyond their borders.

National laws used to stop at the border. In cyberspace, they increasingly stretch around the world, as regulators in Europe, the U.S. and Canada have started asserting legal authority over the internet across country lines.

That is thrusting global tech firms like Google, Facebook Inc. and Microsoft Corp. into a potentially costly legal morass, and setting the stage for conflict over who will—or should—regulate everything from free speech and privacy to cybercrime and taxes.
