The ATJ Commission is composed of 11 Commissioners who are appointed for three-year terms. The Supreme Court appoints seven members, while The Chicago Bar Foundation, Lawyers Trust Fund of Illinois, Illinois Equal Justice Foundation, and Illinois Bar Foundation each name a Commissioner. Justice David K. Overstreet is the Supreme Court liaison to the ATJ Commission.

The ATJ Commission has established committees and subcommittees that are composed of volunteers from different parts of the state with expertise to help in its work. Committees include the Appellate Committee, Community Trust Committee, Court Guidance and Training Committee, Forms Committee (with many subcommittees), Language Access Committee, Remote Appearance Committee, Rules and Policy Review Committee, and Grant Programs Selection Committee.

The Access to Justice Division within the Administrative Office of the Illinois Courts provides staff support to the ATJ Commission and integrates the ATJ Commission’s initiatives into the operations and systems of the judicial branch at a statewide level. Illinois Supreme Court Rule 10-100.
