AZ SB1439

Amends Arizona law to allow county attorneys to prosecute juveniles aged 15-17 as adults if they are "chronic felony offenders" or accused of specified violent felonies including first and second degree murder, forcible sexual assault, armed robbery, or other violent felony offenses.

Defines "chronic felony offender" as a juvenile charged with a class 1, 2, or 3 felony who has had two prior separate adjudications for class 1, 2, or 3 felonies that would constitute historical prior felony convictions if tried as an adult.

Allows juveniles aged 14 and older to be prosecuted as adults for various felonies including class 1-3 felonies and dangerous offenses, with the chronic felony offender provision expanded to apply to this age group as well.

Requires county attorneys to file a notice stating the juvenile is a chronic felony offender when filing a complaint or indictment, and permits juveniles to request a hearing to challenge the chronic felony offender designation.

Mandates that juveniles prosecuted as chronic felony offenders who are convicted and placed on probation must be incarcerated in county jail for up to one year, and requires courts to notify them they now have a historical prior felony conviction subject to mandatory sentencing for future felonies.
