SB 1203 seeks to expand public access to criminal proceedings by ensuring transparency in proceedings under Article 15.17 of the Code of Criminal Procedure. The bill mandates that information about these proceedings, such as their timing, location, and public access mechanisms (including live streaming or videoconferencing links), be published online or displayed at the location of the proceedings. It also requires courts without physical access capabilities to provide virtual access to ensure public observance. The bill provides legal remedies for enforcing public access rights, including filing for writs of mandamus or equitable relief.
