S.B. No. 3073 amends Article 15.17 of the Code of Criminal Procedure to establish a new requirement for magistrates in certain criminal proceedings. Specifically, it introduces a new subsection (h) that mandates magistrates to make written findings within 24 hours if they determine that no probable cause exists for the arrest of an individual. This written documentation is intended to support the magistrate's finding regarding the lack of probable cause.

The bill stipulates that the changes will only apply to offenses committed on or after its effective date of September 1, 2025. Offenses occurring before this date will continue to be governed by the existing law, ensuring that any legal proceedings related to those offenses remain unaffected by the new requirements.
