How Carpenter v. United States applies in Tennessee: state-specific rules, key cases, and bar exam notes for Criminal Procedure (Fourth Amendment).
Tennessee adheres to the principles established in Carpenter v. United States, particularly recognizing the expectation of privacy in cell phone location data. The Tennessee courts evaluate whether law enforcement's access to such data constitutes a search under the Fourth Amendment, emphasizing the importance of a warrant.
In Tennessee, law enforcement must obtain a warrant supported by probable cause before accessing an individual's historical cell phone location data due to the heightened expectation of privacy created by such data.
The Tennessee Supreme Court ruled that warrantless tracking of GPS devices on vehicles constituted a search under the Fourth Amendment.
The court held that the use of cell site location information without a warrant violated the defendant's reasonable expectation of privacy.
This case affirmed that geolocation data is subject to Fourth Amendment scrutiny, requiring a warrant for lawful access.
Tennessee's approach closely mirrors the federal standard established in Carpenter, emphasizing the necessity of a warrant for accessing cell phone location data. However, Tennessee courts may provide additional state-specific protections under their state constitution, potentially offering broader privacy rights than the federal baseline.
The principles from Carpenter v. United States are a key topic in Tennessee's bar exam, especially concerning Fourth Amendment protections and warrant requirements in criminal procedure.
