Carpenter v. United States
United States Supreme Court; Case No. 16-402
Prior Decision
Decision below 819 F.3d 880 (6th Cir. Apr. 13, 2016).
Argument(s)
There has been a dramatic increase in location data generated by cell phones, collected by third parties, and routinely obtained by law enforcement without a warrant. Cell Site Location Information (CSLI) paints a revealing portrait of a person's movements, presenting even greater privacy concerns than the GPS tracker at issue in Jones. The Third-Party Doctrine is "ill-suited to the digital age" and should not apply to CSLI.
