S.B. No. 3073 amends Article 15.17 of the Code of Criminal Procedure to establish a new requirement for magistrates in criminal proceedings. Specifically, it introduces a new subsection (h) that mandates magistrates to make written findings within 24 hours if they determine that there is no probable cause to believe that a person committed the offense for which they were arrested. This written documentation is intended to support the magistrate's finding and ensure transparency in the judicial process.

The bill stipulates that the changes will only apply to offenses committed on or after its effective date of September 1, 2025. Offenses that occurred prior to this date will continue to be governed by the existing law, ensuring that the previous legal framework remains in effect for those cases.
