PPSA FILES BRIEF: Searches of Your Private Data in the Cloud Amount to Illicit State Action

We share our most personal information with banks, telecoms, online search engines, and social media platforms. They know what we spend our money on, with whom we communicate, what we search for, and what we read and post. What could be more personal than that? So whenever we allow corporations to hold such personal information in digital form, can that be taken as a presumption that we’ve just given away our right to privacy?
 
Advocates for a sweeping interpretation of the “third-party doctrine” believe so. The very act of sharing our data, they hold, automatically relinquishes any right to privacy. The government thus doesn’t need to seek a probable cause warrant to review our private information, as the Constitution requires. This is not a matter of theory. A complex web of federal and state law effectively requires communications companies – through a risk of ruinous fines – to search through the content of their customers’ data, and report suspicious results to law enforcement.
 
This is what happened to a Wisconsin man, Michael Gasper. His data was flagged by Snapchat’s automated scans as child sexual abuse material, and reported to the National Center for Missing and Exploited Children. Based on this tip, a law enforcement officer was the first actor to perform a human review of the flagged file, though he did so without bothering to obtain a probable cause warrant, as the Fourth Amendment requires.
 
Initially, a lower court recognized that Gasper had a reasonable expectation of privacy in data he uploaded to the cloud through Snapchat. But the Wisconsin Court of Appeals held otherwise, reasoning that Snapchat’s Terms of Service – a lengthy contract most users “agree” to by checking a box, without ever reading it – eliminated any expectation of privacy. Now PPSA has filed a brief before the Wisconsin Supreme Court demonstrating that this ruling would undermine the heart of the Fourth Amendment. It would also defy a line of U.S. Supreme Court precedent that has long condemned overbroad interpretations regarding government access to third-party data.
 

• PPSA told the Wisconsin Supreme Court that the Fourth Amendment protects the degree of privacy that existed at the Founding despite advances in technology. This is not a reach. In the 18th century, Americans often entrusted their private property – and with it, their personal information – for limited uses by third parties, such as for custody, repair or transportation. Property owners maintained an expectation of privacy over their property, including their documents, when entrusted to a holder. In the 19th century, the Supreme Court held that letters sent through the mail “can only be opened and examined” under a warrant. Why should the cloud be treated any differently?

 

• Snapchat informed users, through its Terms of Service, that it performed automated searches for illicit material – essentially warning that it complies with the law. The state argues that this means Snapchat users have no expectation of privacy. But we told the Wisconsin high court: “when private reporting is mandated with significant penalties for noncompliance, such reports are state action, not private searches.”

 

• What about the eyeball search conducted by the law enforcement officer? We told the court: “But even if they were private searches, law enforcement cannot use them as a stepping stone to later, more expansive searches without complying with the Fourth Amendment.”

We reminded the Wisconsin Supreme Court that the U.S. Supreme Court in Carpenter v. United States held that the government did not have the right to warrantlessly track a suspect’s location through historic call records.
 
We urge the court to realize that we can protect children from exploitation and abuse while taking the time to obtain a warrant based on probable cause. Otherwise, policy will continue to subject the private data of all Americans to warrantless searches.
 
The ransacking of our cloud-based data is much like the “general warrants” of the colonial era, when agents of the Crown could rifle through anyone’s documents at will. This practice was one of the prime outrages that sparked the American Revolution. We should not tolerate the government’s general warrants today.
