The Supreme Court has agreed to hear a case that could redefine digital privacy protections in criminal investigations. At issue is whether law enforcement agencies need a warrant to access encrypted messaging metadata stored by third-party providers.

Legal scholars say the case could establish precedent governing how the Fourth Amendment applies to modern communications technology. The decision is expected to have sweeping implications for criminal prosecution strategies nationwide.

Civil liberties organizations have filed amicus briefs arguing that metadata reveals intimate details of personal life and deserves full constitutional protection.
