US Supreme Court rules in Chatrie v. United States that historical cell phone location data is protected by the Fourth Amendment, regardless of duration or source app, requiring law enforcement to obtain a warrant before accessing any detailed location history from smartphone providers.

This Wire brief sits within Fusion42's coverage of Cybersecurity.

◆ ◆ The Wire takeaway

If you operate a location-data platform or app, you now have a legal duty to refuse warrantless law enforcement requests and to log them — your customers will sue if you don't, and the government has just lost the ability to pressure you into compliance without paper. Build your warrant-handling process this quarter or face class action exposure.
