House Bill No. 3439 amends the Code of Criminal Procedure to enhance the powers and duties of the office of the attorney general regarding the installation and use of tracking equipment and access to certain communications. Key changes include the addition of the attorney general's office as a designated law enforcement agency authorized to conduct criminal investigations and to issue administrative subpoenas for communication records. Specifically, the bill expands the definition of "designated law enforcement office or agency" to include a division or section of the attorney general's office that conducts criminal investigations, alongside existing entities such as county sheriff's departments and municipal police departments.

Additionally, the bill mandates that the attorney general or their designee must be included in the reporting requirements for the issuance of administrative subpoenas and the submission of written lists of authorized peace officers. This inclusion aims to ensure that the attorney general's office is actively involved in overseeing the use of tracking equipment and the management of related communications data. The bill is set to take effect on September 1, 2025.
