This case asks the U.S. Supreme Court to answer whether the warrantless seizure and search of historical cellphone records revealing the location and movements of a cellphone user over the course of 127 days is permitted by the Fourth Amendment. RCFP and 19 media organizations joined as amici in support of petitioner, arguing that the Fourth Amendment requires law enforcement to obtain a warrant to get cellphone location information. The brief explained the historic connection between the First and Fourth Amendments, and argued that long-term tracking of cellphone location information could reveal First Amendment-protected activities and threaten the confidentiality of the newsgathering process.
