Senate Bill No. 1704 aims to enhance the rights of crime victims, witnesses, and their close relatives within the Texas criminal justice system. Key amendments include the introduction of new provisions that ensure victims are informed of modifications to a defendant's sentence within three days, and the requirement for courts to consider the impact of continuances on young victims or those involved in family violence cases. The bill also establishes a new article allowing victims to waive their right to receive certain notifications regarding parole proceedings and the release of defendants, while still providing a mechanism for them to opt back into receiving such information.

Additionally, the bill modifies existing legal language to clarify the rights of victims regarding victim impact statements, ensuring they are informed of their rights and the information that will be provided unless waived. It mandates that victim impact statements include details about the victim's economic loss, physical or psychological injuries, and any changes in personal welfare due to the offense. The bill also emphasizes the importance of notifying victims and witnesses about a defendant's escape or transfer from custody, while allowing for waivers of such notifications. Overall, the legislation seeks to strengthen the support and protection offered to victims and their families throughout the criminal justice process.
