An evenly split federal appeals court ruled Tuesday that it won’t revisit its July decision that allowed Microsoft to squash a US court warrant for e-mail stored on its servers in Dublin, Ireland. The 4-4 vote by the 2nd US Circuit Court of Appeals sets the stage for a potential Supreme Court showdown over the US government’s demands that it be able to reach into the world’s servers with the assistance of the tech sector.
A three-judge panel of the 2nd Circuit had ruled that federal law, notably the Stored Communications Act, allows US authorities to seize content on US-based servers, but not on overseas servers. Because of how the federal appellate process works, the Justice Department asked the New York-based appeals court to revisit the case with a larger en banc panel—but the outcome fell one judge short.
Justice Department spokesman Peter Carr said the agency was reviewing the decision and “considering our options.” Those options include appealing to the Supreme Court or abiding by the ruling.
In its petition for a rehearing, the government said Microsoft didn’t have the legal right to defend the privacy of its e-mail customers, and that the July ruling isn’t good for national security. The authorities believe information in the e-mail could help it investigate a narcotics case.
