H.B. No. 1426 introduces a new provision to the Texas Code of Criminal Procedure, specifically adding Article 18.0216, which prohibits the issuance or enforcement of search warrants, subpoenas, or other court orders related to menstrual health data. The bill defines "menstrual health data" as any information that pertains to an individual's menstrual health or cycles, regardless of the format in which it is recorded. It explicitly states that a magistrate cannot issue any legal orders for the purpose of obtaining this data, and law enforcement agencies are barred from enforcing such orders.

Additionally, the bill stipulates that any menstrual health data obtained in violation of this new article, along with any expert testimony related to that data, will be deemed inadmissible in criminal proceedings. This legislation is set to take effect on September 1, 2025, reinforcing the protection of individuals' menstrual health information from legal scrutiny.
