Criminal Procedure - As introduced, creates a law enforcement investigatory privilege; prohibits a subpoena from being issued for a civil or criminal proceeding for information protected by the law enforcement privilege. - Amends TCA Title 24, Chapter 1, Part 2 and Title 40, Chapter 17, Part 1.

This bill creates a new law enforcement investigatory privilege in Tennessee that protects information gathered during open criminal investigations and prosecutions from being subpoenaed in civil or criminal cases. The privilege applies to information covered under Rule 16 of the Rules of Criminal Procedure and remains in effect until an investigation is closed by the district attorney general, a defendant is acquitted, or a conviction becomes final. Law enforcement officials can still issue subpoenas for their own investigative purposes, but the district attorney general may file motions to stop or change subpoenas that seek protected information. The legislation clarifies that this privilege does not override a criminal defendant's constitutional rights or change existing procedures for law enforcement subpoenas.
