Relating to the age at which a juvenile court may exercise jurisdiction over a child and to the minimum age of criminal responsibility.

This bill raises the minimum age for juvenile court jurisdiction from 10 to 13 years for most offenses, meaning children aged 10-12 will no longer automatically be processed in juvenile court for typical violations. It specifically exempts serious crimes like aggravated assault, murder, sexual assault, or arson - where children aged 10-12 may still be subject to juvenile court. The bill updates definitions in Texas law (Code of Criminal Procedure, Education Code, and Family Code) to reflect these age changes. It directly affects children aged 10-17 who commit offenses, shifting cases involving younger children (10-12) for non-serious violations to adult criminal court.
