Fourth Circuit Reverses Graham: No Warrant Required for Historical Cell Site Location Information

Last year, a panel of the Fourth Circuit decided United States v. Graham, 796 F.3d 332 (4th Cir. 2015). The panel ruled that “the government conducts a search under the Fourth Amendment when it obtains and inspects a cell phone user’s historical [cell site location information (CSLI)] for an extended period of time. . . . Its inspection by the government, therefore, requires a warrant, unless an established exception to the warrant requirement applies.” I discussed Graham here and here. Last week, the en banc Fourth Circuit reversed the panel, ruling that under the third-party doctrine, a cell phone subscriber has no reasonable expectation of privacy in historical cell site location information that he or she shares with a service provider, so it isn’t a Fourth Amendment “search” when law enforcement obtains such information, and a warrant isn’t required. The en banc opinion is here. This post discusses the opinion and considers the possibility of Supreme Court review or action by Congress.

Advice to Officers After Graham

Aug. 5, 2015), that an officer who obtained two suspects’ cell site location information (CSLI) without a search warrant violated the Fourth Amendment. (The officer used a court order based on a lower standard, as purportedly authorized by the relevant federal statute, 18 U.S.C. § 2703(d).) I’ve had a number of practical questions about Graham from officers, agency attorneys, and judges, and I thought that I would collect some of the questions here.

Resentencing on Eighth Amendment Grounds

Some inmates are serving long sentences for older crimes that would receive a much shorter sentence under today’s law. It is clear at this point that they cannot have today’s law applied to them retroactively, as Jessie discussed in this prior post. That’s true for inmates who received longer sentences under Fair Sentencing, State v. … Read more

Graham v. Florida

The Supreme Court of the United States issued two noteworthy opinions yesterday. In United States v. Comstock (a case that originated out of North Carolina) the Court reversed the Fourth Circuit and upheld the federal government’s power to civilly commit a mentally ill, sexually dangerous federal prisoner beyond the date he would otherwise be released … Read more
