If Edward Snowden gave federal courts the means to declare the National Security Agency’s data-gathering unconstitutional, Sonia Sotomayor showed them how.
It was Sotomayor’s lonely concurrence in U.S. v Jones, a case involving warrantless use of a GPS tracker on a suspect’s car, that the George W. Bush-appointed Judge Richard Leon relied on when he ruled that the program was likely unconstitutional last week. It was that same concurrence the White House appointed review board on surveillance policy cited when it concluded government surveillance should be scaled back.
“It may be necessary to reconsider the premise that an individual has no reasonable expectation of privacy in information voluntarily disclosed to third parties,” Sotomayor wrote in 2012. “This approach is ill suited to the digital age, in which people reveal a great deal of information about themselves to third parties in the course of carrying out mundane tasks.”
Not a single other member of the high court signed onto Sotomayor’s concurrence; her three Democratic appointed colleagues sided with a narrower one written by Justice Samuel Alito. Though all nine justices agreed that police would likely need to get a warrant to place a GPS device on a suspect’s car, it was Sotomayor who was willing to argue that modern technology had essentially changed the meaning of what privacy means when so much of our personal information and history is preserved online, and can be easily collected by the government in mass quantities. When the Framers of the Constitution wrote of “persons, houses, papers, and effects,” they could not have imagined cloud storage or cell phone location tracking.
The legal challenges to the NSA’s metadata program may never reach the Supreme Court. But if they do, the high court will have to reckon with Sotomayor’s reasoning in Jones.
“Sotomayor’s concurrence in Jones is already proving to be extremely influential,” says Adam Winkler, a law professor at the UCLA School of Law. “Sotomayor was willing to face up to the challenges of new technology, that people still have a right to privacy even if they’re giving up information to a cell phone provider or doing a search on Google.” More than just a legal opinion, Sotomayor penned a legal manifesto on privacy for a digital age debated among Fourth Amendment scholars and brandished by civil libertarians seeking to prevent the coming of a digital government panopticon.
“GPS monitoring generates a precise, comprehensive record of a person’s public movements that reflects a wealth of detail about her familial, political, professional, religious, and sexual associations,” Sotomayor wrote–a description that could easily be applied to all sorts of digital records. Judge Leon cited that sentence in his ruling that the NSA’s metadata gathering was likely unconstitutional, explaining how “[r]ecords that once would have revealed a few scattered tiles of information about a person now reveal an entire mosaic–a vibrant and constantly updating picture of the person’s life.”
The legal argument behind the NSA’s data-gathering is based in part on long-standing Fourth Amendment doctrine that when we give up information to third parties like the phone company, it’s no longer private. Civil liberties groups had long argued that view was increasingly anachronistic, but it was Sotomayor’s concurrence that, for the first time, gave those theories the legitimacy that comes with being adopted by a member of the high court. Sotomayor would provide civil liberties groups with a firm hand-hold as they sought to challenge the government’s warrantless acquisition of all types of digital records, from cell tower data to the NSA’s metadata program.
“Justice Sotomayor’s concurrence in Jones was the first time a Supreme Court justice seemed to acknowledge and speak directly to that new reality,” said Catherine Crump of the ACLU, who helped write the group’s Supreme Court brief in Jones. “To have a Supreme Court Justice acknowledge that there is a difference between a few discrete pieces of information about someone and the complete records you can now gather in the era of big data made us feel like we were on the right path.”
Winkler compared Sotomayor’s concurrence in Jones to Justice Louis Brandeis’ concurrence in Whitney v. California, whose expansive interpretation of the First Amendment we now take for granted. “I think that Sotomayor’s concurrence is going to be seen much the same way,” Winkler said.
