The proposed bill, known as the John Nolley Act, introduces new regulations regarding the use of in-custody informant testimony in criminal trials. It adds Article 38.0751 to Chapter 38 of the Code of Criminal Procedure, defining key terms such as "in-custody informant" and "benefit." The bill stipulates that such testimony is inadmissible unless the prosecution notifies the defendant at least 21 days before the trial and a pretrial hearing confirms the reliability and credibility of the informant's testimony, ensuring that any benefits offered do not unduly influence the informant.

Additionally, the bill mandates that the prosecution provide all relevant information and records to the defendant at least 10 days before the admissibility hearing. It also allows for continuances of the hearing or trial if either party requires more time to prepare. If the informant's testimony is admitted, the jury must be instructed to disregard it unless they find that the informant was not unduly influenced and that the testimony is truthful. The changes will apply to criminal proceedings commencing on or after the effective date of the Act, which is set for September 1, 2025.
