Five standing Advisory Committees of the Judicial Conference have been established, and are charged, respectively, with drafting proposed amendments to the: Federal Rules of Civil Procedure; Federal Rules of Criminal Procedure; Federal Rules of Bankruptcy Procedure; Federal Rules of Appellate Procedure; and Federal Rules of Evidence. Members of the Advisory Committees include judges, representatives from the Department of Justice, law professors, and practicing attorneys. The Advisory Committees propose rules, subject them to public comment, and then submit them to the Standing Committee on Rules of Practice and Procedure, which in turn submits them to the Judicial Conference, which recommends them to the Supreme Court for approval. Explanatory notes of the drafting Advisory Committee are published along with the final adopted rules, and are frequently used as an authority on the interpretation of the rules. Other active policy areas concern the operation of CM/ECF, the Case Management/Electronic Case Files system, and PACER, the electronic public access service for United States federal court documents. On occasion, the Conference has authorized investigations of federal judges accused of criminal malfeasance. Those deemed guilty have been referred to the House Judiciary Committee for impeachment. This has happened three times during the 21st century. Administrative Office of the United States Courts The Administrative Office of the United States Courts (AO) is the administrative agency of the United States federal court system. The AO is the central support entity for the federal judicial branch. It provides a wide range of administrative, legal, financial, management, program, and information technology services to the federal courts. It was established in 1939. The AO is directly supervised by the Judicial Conference, and implements and executes Judicial Conference policies, as well as applicable federal statutes and regulations. The AO facilitates communications within the judiciary and with Congress, the executive branch, and the public on behalf of the judiciary. Judicial councils Judicial councils are panels of each federal judicial circuit that are charged with making "necessary and appropriate orders for the effective and expeditious administration of justice" within their circuits. Among their responsibilities is judicial discipline, the formulation of circuit policy, the implementation of policy directives received from the Judicial Conference, and the annual submission of a report to the Administrative Office on the number and nature of orders entered during the year that relate to judicial misconduct. Each judicial circuit consists of the chief judge of the circuit and an equal number
