The U.S. Court of Appeals for the Second Circuit ruled in favor of Microsoft in a closely watched case involving the government’s ability to use search warrants to obtain electronic communications stored abroad. Reversing the district court, the Second Circuit concluded that the U.S. government lacked the authority to issue a warrant under the Stored Communications Act (SCA) to force Microsoft to turn over emails stored on a server in Ireland. The decision is a major win not just for Microsoft, but for American cloud service providers who, post-Snowden, have had to fend off criticisms from European competitors and privacy advocates who claimed that data stored with American companies or their foreign subsidiaries was not safe from the prying eyes of the U.S. government. (Steptoe authored an amicus brief on behalf of a group of cloud, internet, and technology companies, siding with Microsoft.)
