With society’s increasing dependency on ever-changing technology, particularly cell phones, the need to protect individuals’ privacy in criminal investigations is paramount.[1] Cell phone users  no longer share personal information with their cell phone carriers but with apps and search engines.[2] Furthermore, cell phone carriers are adding smaller cell sites, in addition to macro cell towers, which allows cell phone carriers to determine a cell phone’s location within smaller and more targeted boundaries.[3] While this cell phone technology is evolving at a fast pace, the law is slow to adapt.[4] The judiciary and legislatures, both state and federal, must anticipate emerging technology in order to fully protect individuals’ privacy.[5]

The Supreme Court’s recent decision in Carpenter v. United States may give insight into how the Court will handle digital privacy in the near future.[6] In a narrow ruling, the majority held that law enforcement’s acquisition of over 127 days of cell-site location information (CSLI) constituted a search under the Fourth Amendment and required a warrant.[7] The majority reasoned that tracking a cell phone’s location for that length of time gives a complete record of an individual’s whereabouts.[8] Similar to tracking GPS information from a car, tracking a cell phone’s location reveals a person’s “familial, political, professional, religious, and sexual associations.”[9] The intimate and exhaustive nature of the information led the Court to conclude that the warrantless search was unconstitutional.[10]

Proponents of increased protection of privacy in the digital era hailed this decision as a win.[11] They argue because the third-party was developed in the 1960s and ‘70s, the doctrine does not take into account the precision and invasiveness of information available today.[12] The majority in Carpenter addressed these concerns and declined to extend the third-party doctrine, citing the nature of the data collection and recognizing that the necessity of cell phones in modern life renders the voluntary exposure rationale of the third-party doctrine mute in the particular circumstance.[13] Despite its narrow ruling, proponents of digital privacy have been hopeful the rationale may be applied to other information held by third parties, such as search history, emails, and more.[14] Nathan Wessler, ACLU attorney who argued before the Court on Carpenter, stated this decision “provides a path forward for safeguarding other sensitive digital information in future cases–from…smart-home appliances…[to] technology that is yet to be invented.”[15]

However, after the recent confirmation of Justice Brett Kavanaugh, the dissent’s approach, which considered the majority’s ruling an “undue restriction” on law enforcement, may be the Court’s future approach to digital privacy with cellphones.[16] During Justice Kavanaugh’s confirmation process, proponents of increased digital privacy criticized several of his previous rulings .[17] In Klayman v. Obama, Justice Kavanaugh wrote a concurrence that upheld the constitutionality of the National Security Agency’s (NSA) bulk telephone metadata program from the Bush Administration.[18] The NSA would collect information about numbers dialed and the length of phone calls without a warrant and store this information.[19] The FBI could look through this data with permission from the Foreign Intelligence Surveillance Act court.[20] In an unprompted concurrence, where the majority did not even write a full opinion, Justice Kavanaugh wrote that this constituted a “special need” that outweighs the intrusion on individual liberty.[21]

For proponents of increased digital privacy, the more concerning decision by Justice Kavanaugh is his joining of the dissent for the D.C. Circuit Court of Appeals in United States v. Jones.[22] Justice Kavanaugh and the dissent found that Jones’s reasonable expectation of privacy in his movements on public highways was nonexistent, despite the month long GPS tracking.[23] This is in stark contrast to the majority ruling in Carpenter that relied on the Supreme Court’s concurrence in Jones, which opposed Justice Kavanaugh’s reasoning.[24] The Jones majority used a property-based rationale to determine the tracking was an unconstitutional search, but the concurrence in Jones foresaw longer term GPS monitoring, possibly using cell phone data, as “impinging on expectations of privacy.”[25] In Justice Kavanaugh’s Senate Judiciary Committee questionnaire, he stated he was only applying a property-based rationale as later implemented by the Supreme Court majority;[26] however, the dissent he joined did clearly state that Jones had no expectation of privacy.[27] Justice Kavanaugh’s opinion  is not likely to change if the facts in front of him included a month-long surveillance in Jones to a little over two months in Carpenter.[28]

It is unclear how Justice Kavanaugh will rule on issues of digital privacy. As an appellate judge, he was bound by precedent in interpreting the third-party doctrine.[29] However, since the Carpenter decision was a narrow ruling to its specific facts, it is more likely that Justice Kavanaugh will move the Court to the direction of the dissent in Carpenter. Proponents of increased digital privacy may have been too hasty with their celebrations.
