On January 23, the Supreme Court upheld a D.C. Circuit decision suppressing evidence obtained from a GPS device attached to an alleged drug dealer’s Jeep (United States v. Jones). Remarkably, the decision was 9-0 in favor of suppression – a surprising fact in itself given the pro-law-enforcement leanings of some of the Justices. Even more remarkable is that the Court split 5-4 on the rationale for suppressing the evidence in a way not involving the usual 5-4 lineups. Justice Scalia authored the opinion of the Court, joined by, inter alia, Justice Sotomayor. Justice Alito, usually one of Justice Scalia’s closest allies, authored the concurrence which contained more than its fair share of shots at the majority’s reasoning.
The facts are relatively simple. The federal government obtained a warrant to install a GPS tracking device on a Jeep belonging to Jones’ wife within 10 days in the District of Columbia. On the 11th day, the feds surreptitiously attached the GPS device to the Jeep in a parking lot in Maryland – hence beyond that which was allowed by the warrant. For the next month, the feds tracked Jones and were successful in linking up his presence at a “stash house” that contained massive quantities of cash and drugs. Jones unsuccessfully sought to suppress the bulk of the evidence from the GPS and he was convicted and sentenced to life in prison. The D.C. Circuit overturned the conviction on the grounds that the evidence from the GPS tracking device should be suppressed because the installation and tracking violated Jones’ Fourth Amendment rights.
The Supreme Court unanimously upheld the D.C. Circuit’s suppression ruling but split 5-4 on the reasoning. Justice Scalia, writing for the Court, equated the illegal search as an old-fashioned trespass on Jones’ “effects.” (The Fourth Amendment provides: “The right of the people to be secure in their persons, houses, papers and effects against unreasonable searches and seizures shall not be violated.”) Relying upon earlier interpretations of the Fourth Amendment that themselves relied heavily upon traditional notions of trespass on property, the majority characterized the GPS’s installation and subsequent tracking as, in effect, a physical trespass. The majority distinguished two earlier decisions that had upheld the use of “beepers” in tracking illegal contraband. In both cases, per the majority, the “beepers” were installed in the contraband with the approval of the then-owner of the contraband that later found their way into the possession of the person ultimately stung by the “beeper’s” data.
Justice Alito, writing for the four concurrences, criticized the majority’s reasoning as essentially antiquated. Justice Alito noted that the physical-trespass line of Fourth Amendment authority gave way to what today is the “reasonable expectation of privacy” test. (The leading case, Katz v. United States, involved what was held to be an illegal attachment of a listening device to a public telephone booth. The Court held that the person in the telephone booth had a “reasonable expectation of privacy” that was violated by the attachment of the listening device.) Justice Alito would hold that the GPS device in Jones’ case violated his reasonable expectation of privacy.
So what do we make of this? Studying the opinions, it is clear that Scalia and company did not want to issue too broad an edict, understanding full well that current technology poses a myriad of situations for police eavesdropping that dramatically dwarfs what was possible under earlier wiretap technology. Alito, on the other hand, was prepared to stake a flag in the ground that persons today in our digital world continue to enjoy certain privacy protections under the Fourth Amendment – a holding that would have had more far reaching consequences.
I believe the criticism leveled by some to the majority rationale is overstated. The decision is still a clear win for privacy advocates. We could have seen five votes equating the GPS device to the “beeper” cases noted above which would have eviscerated Fourth Amendment rights in the digital context. Instead, there are at least four votes for recognizing Alito’s “reasonable expectation of privacy” test in the digital context, and, while Justice Sotomayor joined Justice Scalia in his opinion, she (and even Justice Scalia on a closer read) recognize that the “property/trespass” protection recognized in Jones was in addition to, not in lieu of, the “reasonable expectation of privacy” test. In short, privacy advocates live to fight another day in challenging other digital surveillance techniques that arguably go too far.
