Fourth Circuit: Apartment Front Door Was Not Curtilage

In U.S. v. Johnson, 148 F.4th 287 (4th Cir. 2025) (summarized here), the U.S. Court of Appeals for the Fourth Circuit recently rejected a Fourth Amendment challenge to a canine sniff at the front door of the defendant’s apartment. My colleagues Jeff Welty and Shea Denning have blogged about the issue of curtilage and multi-unit dwellings like apartment buildings in the past (here, here, and here), but Johnson is a good refresher on those principles. Read on for the details.

An Update on Law Enforcement Use of Drones

I recently participated in a WFAE radio show about law enforcement use of drones, along with a captain from the Winston-Salem Police Department and an advocate from the ACLU. I thought the discussion was excellent, with a nice balance of perspectives. In the course of preparing for the program, I did an environmental scan about how law enforcement officers are currently using drones, and looked for court opinions about some of the legal questions presented by drone use. This post summarizes what I learned before and during the show.

When Can the Police Seize a Cell Phone Incident to Arrest, and How Long Can They Keep It?

Riley v. California, 573 U.S. 373 (2014), holds that the contents of a cell phone may not be searched incident to arrest, but allows for the possibility that the phone itself may be seized incident to arrest. This post addresses when such a seizure is permissible and how long it may last.

Border Searches of Electronic Devices

North Carolina doesn’t have a land border with Mexico or Canada, so most people don’t think of us as a border state. But we are. We have a maritime border and several international airports that courts have deemed the functional equivalent of a border. Fourth Amendment protections are greatly reduced at the border, and United States Customs and Border Protection (CBP), the federal agency responsible for securing the border, reports that in 2023 it conducted border searches of electronic devices belonging to 41,467 travelers. This post considers when law enforcement officers may search an international traveler’s electronic devices.

Fourth Circuit Strongly Suggests Including Temporal Limitations on Search Warrants for Social Media Account Information

Earlier this year, the Fourth Circuit decided United States v. Zelaya-Veliz, 94 F.4th 321 (4th Cir. 2024). Phil summarized it here when it came out, but we thought it merited its own post because of its extended discussion of how the Fourth Amendment applies to search warrants for social media account information. The court’s discussion of the need for temporal limitations in such warrants is especially noteworthy, as is the court’s analysis of the scope of the information seized pursuant to the warrants approved by the court. We’ll start with a recap of the case, and then end with some thoughts for law enforcement and prosecutors, and for defenders.

“Here Is Your Stuff Back, Man”: When Returning a Driver’s License and Registration Doesn’t Terminate a Stop

Consider a fact pattern that takes place every day, all across the country: a police officer stops a motorist for a traffic infraction, runs the motorist’s license through a computer database and finds nothing exceptional, and returns the driver’s license and registration, perhaps along with a warning or a citation. The officer then asks the driver for consent to search the driver’s car. The driver consents and the officer finds drugs. Did the officer do anything wrong in this situation? Are the drugs subject to suppression? The answers depend on whether the traffic stop ended when the officer returned the driver’s license. As a recent case shows, that can be a complex determination.
