Apple has joined Microsoft, Amazon and Cisco in filing an amicus brief in support of Google’s refusal to hand over email records to the FBI, Business Insider reports. The FBI’s warrant requests records stored in Google’s servers overseas, and Google has argued against applying the Stored Communications Act to data stored outside the U.S. The brief filed by the other companies argues that seeking emails from a foreign data center would be perceived as an “extraterritorial act on the part of the U.S. government” and invite other nations to begin demanding records currently kept on U.S. soil for their own investigations. A Pennsylvania court has ruled that Google must surrender the documents to the FBI, but the company has said it will fight the ruling.
