Travis LeBlanc v. United States Privacy and Civil Liberties

Plain English (For Everyone)

The government needs a warrant, like a judge's permission slip, to get your past location data from your cell phone company. This is because your location history reveals very private details about your life, and collecting it without a warrant is an unreasonable search under the Fourth Amendment.

For Legal Practitioners

The CADC held that the government's warrantless acquisition of historical cell-site location information (CSLI) constitutes a Fourth Amendment search. This ruling aligns with precedent establishing that CSLI implicates a reasonable expectation of privacy, necessitating a warrant supported by probable cause for its collection.

For Law Students

This case establishes that obtaining historical cell-site location information (CSLI) from a cell carrier is a 'search' under the Fourth Amendment. Therefore, the government must obtain a warrant based on probable cause before accessing such data, as it reveals intimate details of an individual's life.

Newsroom Summary

A federal appeals court ruled that the government needs a warrant to access your past location data from your cell phone provider. The court found that this information is private and collecting it without a judge's approval violates the Fourth Amendment.
