AZ SB1089

Amends Arizona law to define "chronic felony offender" for juveniles as one who has two prior and separate adjudications for conduct constituting a historical prior felony conviction, with at least one involving intentional or knowing physical injury.

Excludes class 4, 5, or 6 felony adjudications from the chronic felony offender definition unless the offense involved use of a deadly weapon or dangerous instrument, or violations of specific assault and kidnapping statutes.

Requires county attorney to file notice when charging a juvenile as a chronic felony offender, which confers jurisdiction over the juvenile in criminal court.

Allows juveniles to file a motion for a hearing before trial to challenge chronic felony offender status; the state must prove the designation by a preponderance of evidence or the case transfers to juvenile court.

Makes any felony offense committed by a chronic felony offender subject to mandatory adult criminal prosecution for juveniles ages 14-17, in addition to other enumerated violent felonies.
