EFF Asks Court to Unseal Secret Docket in Case Involving Wiretap of Encrypted Facebook Messenger Calls
EFF joined an effort to unseal court records today in a groundbreaking case where the government reportedly tried to force Facebook to compromise the encryption in Facebook Messenger voice calls. Earlier this year, Reuters reported that the government sought the company’s assistance in carrying out a wiretap and intercepting Messenger calls in connection with the investigation of suspected MS-13 gang activity. Although later reports indicated that the court ruled Facebook did not have to comply, the entire proceeding took place under seal, so we could only speculate about the legal arguments made by both sides and the case’s implications for user security.
According to press reports, the U.S. Department of Justice tried to get Facebook to turn over customer data and unencrypted Messenger voice calls using a wiretap order. To our knowledge, this hasn’t been done before, and it raises novel questions about modern communication providers’ duties to assist with wiretaps involving encryption. The Wiretap Act is written to cover companies that have the ability to monitor communications traveling over their networks, like traditional phone companies. Facebook, however, likely cannot decrypt encrypted Messenger texts and voice calls. (Read our explanation of how we think Facebook Messenger secures communications.)
In our petition filed today in the United States District Court for the Eastern District of California, EFF, the ACLU, and Riana Pfefferkorn of Stanford Law School’s Center for Internet and Society seek to shed light on this important issue. We’re asking the court to release all court orders and related materials in the sealed Messenger case.
Given the importance of encryption in widely used consumer products, it is a matter of public interest any time law enforcement tries to compel a company to circumvent its own security features. As with the San Bernardino showdown, where the FBI attempted to compel Apple to decrypt the shooter’s phone using a legally questionable interpretation of the All Writs Act, the government often downplays the risks to users. As we said when the Messenger case was first reported, we “fear that this is one of a series of moves by the government that would allow it to chip away at users’ security, done in a way such that the government can claim it isn’t ‘breaking’ encryption.”
More broadly, access to the law, including court orders, judicial opinions, or regulations and city codes, is a fundamental property of democracy: how can people be held to a rule when they do not know and do not have the ability to know what that rule is? And how can we be sure that the government is applying a rule equally? The tradition of access to the law has existed since the colonies and is enshrined in the First Amendment, but with modern surveillance practices, law enforcement is increasingly requesting that judges hide legal proceedings from the public—even after the government has finished an investigation and has a little need for secrecy.
Law enforcement shouldn’t be given secret standards and allowances for how they can access encrypted data and surveil the public. We hope that the court decides to allow some sunshine into this secret docket.
