The Arizona Criminal Justice Commission's (ACJC) Drug, Gang and Violent Crime program area is responsible for the administration of the Edward Byrne Justice Assistance Grant, Residential Substance Abuse Treatment for State Prisoners, and Special Prosecution programs.

In addition to grant administration and monitoring responsibilities, this area also distributes Fill the Gap funds to county attorney and indigent defense offices in all 15 counties. Signed into law in 1998, Fill the Gap legislation established a formula grant program to improve the flow of criminal cases in the criminal justice system. The goal of the program is to dispose of 90 percent of cases within 100 days from filing and 99 percent within 180 days. This goal is based on the realization that the work of the courts, county attorneys and indigent defense are inter-related and all elements must move smoothly through the system to reduce case-processing time. Arizona Revised Statute §41-2409 authorizes the Arizona Criminal Justice Commission to distribute and oversee a portion of Fill the Gap funds for the county and defense attorneys to realize this goal. The Administrative Office of the Courts (AOC) manages Fill the Gap funds distributed to the courts.
