Fourth Amendment Webinar Series Part 1 – Four Years After Carpenter: How to Keep Expanding Fourth Amendment Rights in the Digital Age

Time: 1:00 PM - 2:15 PM (EDT)

In Carpenter v. United States, 138 S. Ct. 2206 (2018), the Court held the government must obtain a warrant supported by probable cause before acquiring cell-site-location-information. This marked a watershed expansion of Fourth Amendment rights in the digital age. How have lower courts interpreted the decision in the last four years? What other government uses of location data, surveillance techniques, and sensitive digital information should be limited by Carpenter’s logic? Hear from the attorney who argued Carpenter about its implications and strategies going forward.


Nate Freed Wessler is a deputy director of the ACLU’s Speech, Privacy, and Technology Project, where for the last decade he has focused on litigation and advocacy around surveillance and privacy issues, including constraining government requests for sensitive data held by third parties, use of surveillance technologies, and searches of electronic devices. In 2017, he argued Carpenter v. United States in the U.S. Supreme Court, a case that established that the Fourth Amendment requires law enforcement to get a search warrant before requesting cell phone location data from a person’s cellular service provider.
