The Judicial Conference has carried out many of its responsibilities through the use of committees, created by the Conference and with members appointed by the Chief Justice.

Between 1922 and 1939, the Conference created a limited number of short- term committees to address specific issues. After the creation of the Administrative Office of the U.S. Courts in 1939, which operated under the supervision of the Judicial Conference, the Conference more frequently created committees, many of which served as permanent standing committees. After 1939 committee membership began to include judges who were not members of the Judicial Conference.

In September 1955, Chief Justice Earl Warren, as the presiding officer of the Conference, discharged the existing committees and reconstituted 10 committees, seven of which he designated standing committees. (See Report of the Proceedings of the Judicial Conference, September 1955, pp. 30-32). The number of committees grew until September 1968, when the Conference again revised the number and jurisdiction of the committees. The Conference created three General Committees of indefinite tenure and broad membership to serve the "overall requirements of the Conference" and whose work would be completed largely through subcommittees. These were Court Administration, Administration of the Criminal Law, and Operation of the Jury System. The Conference also created a series of standing committees that would have fewer members and be focused on more specific needs, like preparing the budget or intercircuit assignment of judges. Finally, the Conference continued to establish special committees to exist for only short durations. (See Report of the Proceedings of the Judicial Conference, September 1968, pp. 43-46).

The Judicial Conference revised the committee structure again in 1987. The Conference ended the formal distinction between general, standing, and special committees. The Conference continued thirteen of the existing committees, dissolved five of them, and created seven new committees, three of which were formed out of subcommittees of the former Court Administration Committee. The Conference also established a policy whereby every five years, each committee must recommend to the Executive Committee whether it should be continued or abolished, with supporting justification. (See Report of the Proceedings of the Judicial Conference, September 1987, pp. 57-60).
