Relating to the training of prospective grand jurors and to grand jury proceedings.

SB 1630 requires prospective grand jurors in Texas to complete mandatory training before serving. It also restricts grand juries from investigating the same person for the same offense twice unless new material evidence is presented. The bill adds requirements to record witness testimony (excluding deliberations) and keeps grand jury proceedings confidential. Additionally, it establishes new discovery rules allowing accused or suspected persons to review specific documents related to the investigation, though work product and privileged materials remain excluded. These changes apply directly to grand jurors, prosecutors, and individuals under investigation.
