SCOTUS Rules Law Enforcement Can’t Aquire Cell Site Records Without a Warrant

Supreme_Court_Building_at_DuskIn a 5-4 decision (and wait until you read who), the US Supreme Court has ruled that cell site records are protected by the Fourth Amendment.

Holding: The government’s acquisition of Timothy Carpenter’s cell-site records from his wireless carriers was a Fourth Amendment search; the government did not obtain a warrant supported by probable cause before acquiring those records.

Carpenter v. United States

1. The Government’s acquisition of Carpenter’s cell-site records was a Fourth Amendment search. Pp. 4–18.

(a) The Fourth Amendment protects not only property interests but certain expectations of privacy as well. Katz v. United States, 389 U. S. 347, 351. Thus, when an individual “seeks to preserve something as private,” and his expectation of privacy is “one that society is prepared to recognize as reasonable,” official intrusion into that sphere generally qualifies as a search and requires a warrant supported by probable cause. Smith v. Maryland, 442 U. S. 735, 740 (internal quotation marks and alterations omitted). The analysis regarding which expectations of privacy are entitled to protection is informed by historical understandings “of what was deemed an unreasonable search and seizure when [the Fourth Amendment] was adopted.” Carroll v. United States, 267 U. S. 132, 149. These Founding-era understandings continue to inform this Court when applying the Fourth Amendment to innovations in surveillance tools. See, e.g., Kyllo v. United States, 533 U. S. 27. Pp. 4–7.

I’m interested in reading this one because Kennedy, Alito, Thomas, and Gorsuch…dissented.

You read that right.

More when I’ve gotten through it all.
