The court’s decision may complicate the transfer of data outside the European Union.
The EU’s highest court on Thursday invalidated an agreement allowing large technology companies to transfer data to the US.
The decision of the European court of justice to invalidate the Privacy Shield program will make it more difficult to transfer any data outside the EU.
Now, regulators may have to check new data transfers because of concerns that the US government may be tracking personal data for national security purposes.
The case arose after former us national security Agency contractor Edward Snowden reported in 2013 that the US government was monitoring people’s data and communications on the Internet.
His revelations included information that Facebook gave us intelligence agencies access to the personal data of Europeans.
