Administrative Office of the U.S. Courts

Administrative Office of the U.S. Courts

The federal judiciary employs more than 30,000 people — clerks, probation officers, pretrial services officers, public defenders, librarians, and IT staff — across 94 judicial districts and 13 circuits. The Administrative Office of the United States Courts (AO) is the bureaucratic infrastructure that makes this system run. It manages the judiciary's budget, human resources, technology, and statistics; supervises probation and pretrial services; administers the Defender Services program funding public defenders; and serves as the professional staff arm of the Judicial Conference of the United States. To most people the AO is invisible — but it is the reason federal courts can function as a coherent national institution rather than 94 independent fiefdoms.

Key AO publicationsAnnual Statistical Tables; Federal Court Management Statistics; Judicial Business of the United States Courts
  • 28 U.S.C. § 601 — Creation (the Administrative Office of the United States Courts is established; the Director is the administrative officer of the courts)
  • 28 U.S.C. § 602 — Employees (the Director appoints a Deputy Director and such other employees as the Director considers necessary; employees are not in the competitive civil service — judiciary employees operate under their own personnel system)
  • 28 U.S.C. § 604 — Duties of Director (a comprehensive list: supervising all administrative matters in the courts except the Supreme Court; submitting the judiciary's budget to Congress; apportioning funds to the courts; collecting and compiling statistics on federal court business; supervising probation officers; overseeing defender services; managing the court library system; maintaining court technology; and reporting annually to the Judicial Conference)
  • 28 U.S.C. § 605 — Budget estimates (the Director transmits the judiciary's budget to the Office of Management and Budget; crucially, the budget must also be transmitted directly to Congress, giving the judiciary a degree of independence from executive branch budget review — unlike most other federal agencies, the judiciary submits its own budget request)
  • 28 U.S.C. § 606 — Dress of administrative office (the AO Director and staff wear no uniforms; this provision reflects the judiciary's civilian character)
  • 28 U.S.C. § 607 — Practice of law (the Director may not engage in the practice of law while serving)
  • 28 U.S.C. § 609 — Courts' appointive power (the AO does not control court personnel; each court retains the authority to appoint its own clerks and other employees — the AO provides policy frameworks and funding but does not directly supervise court staff)
  • 28 U.S.C. § 610 — Courts defined (references to "courts" throughout this chapter mean the courts of appeals, district courts, Court of International Trade, and other Article III courts, but not the Supreme Court, which administers itself separately)
  • 28 U.S.C. § 331 — Judicial Conference of the United States (the Chief Justice presides; the conference is composed of the chief judge of each circuit, the chief judge of the Court of International Trade, and a district judge from each circuit elected by the district judges; the Conference makes policy for the administration of the federal courts and carries out the rules-prescribing function)

How It Works

The Administrative Office serves as the professional staff arm of the Judicial Conference of the United States — the 27-judge governing body chaired by the Chief Justice that sets national policy on court technology, judicial ethics, rules of procedure, and judicial conduct. The AO implements Conference policy, manages day-to-day administration, and provides expertise through the committees where the Conference does its substantive work. One of the AO's most consequential functions is preparing the federal judiciary's annual budget request, which the judiciary submits directly to Congress in addition to routing through OMB — a separation-of-powers practice that distinguishes it from executive agencies. The judiciary's budget covers judicial salaries and benefits, court security, probation and pretrial services, Defender Services, court technology, and courthouse construction and maintenance.

The AO is also the primary publisher of federal court statistics — releasing the annual "Judicial Business of the United States Courts" report, the authoritative source on filings, terminations, pending caseloads, and judicial workload in every district and circuit. The AO's Defender Services division administers the Criminal Justice Act program, funding approximately 80 Federal Public Defender offices and CJA panel attorneys who represent indigent federal defendants; this budget is entirely separate from the Justice Department's U.S. Attorney's Office budget, and the AO advocates for adequate defender funding in its annual submissions. The AO also oversees the federal probation and pretrial services system — about 5,000 officers in 94 districts who supervise defendants on pretrial release, conduct pre-sentence investigations, and manage post-incarceration supervised release — and maintains the federal courts' technology infrastructure, including PACER (Public Access to Court Electronic Records), the CM/ECF case management system, and judicial cybersecurity programs.

How It Affects You

<!-- pria:personalize type="impact" -->

If you're a litigant, party, or attorney in a federal case: The Administrative Office manages the two systems you'll interact with daily. CM/ECF (Case Management/Electronic Case Filing) is the mandatory electronic filing system for all federal courts — attorneys in federal cases must file electronically through PACER/CM/ECF. PACER (Public Access to Court Electronic Records) at pacer.gov gives public access to virtually all non-sealed federal court documents: complaints, motions, opinions, docket entries, transcripts. The fee is $0.10 per page, capped at $3.00 per document — a 30-page document costs $3.00, not $3.00. Free access applies to users whose quarterly charges don't exceed $30 (roughly 300 pages). Fee waivers are available for individuals who can't afford the fee; apply through the PACER Service Center at pacer.gov/psco/cgi-bin/pa-forms.pl or call 800-676-6856. PACER's search function lets you look up cases by party name, attorney, judge, or case number across all federal districts simultaneously through PACER Case Locator at pcl.uscourts.gov — essential for checking whether a counterparty has related litigation pending elsewhere. Some opinions are also free through the CourtListener project at courtlistener.com, which mirrors much of PACER's data without per-page fees.

If you're on federal probation, supervised release, or pretrial supervision: Federal probation and pretrial services officers are employees of the federal judiciary — supervised through the AO — not employees of the executive branch's Department of Justice or Bureau of Prisons. This structural independence is intentional: they report to the court, not to prosecutors. Practically, this means: your probation officer's recommendations for condition modifications, revocations, or early termination go to your sentencing judge, who retains supervisory authority. Your officer also prepares the Presentence Investigation Report (PSI/PSR) — the document that heavily influences your sentence before you serve it and the supervision plan after you're released. If you believe your PSR contains factual errors, you have the right to review it (usually 35 days before sentencing) and submit objections; the judge must rule on material objections. If you're seeking a modification to your supervision conditions, your officer's recommendation carries significant weight with the judge; building a cooperative relationship with your officer is practically important. The Federal Public Defenders (fd.org) and National Association of Criminal Defense Lawyers (NACDL) at nacdl.org have resources on federal supervision rights.

If you're a researcher, journalist, or policy analyst tracking the federal courts: The AO is the primary source of federal judiciary data. Its annual "Judicial Business of the United States Courts" report — free at uscourts.gov/statistics-reports/judicial-business-united-states-courts — is the definitive statistical record: civil filings by district and case type, criminal prosecutions by charge category, bankruptcy filings, judge workload by district, median times from filing to disposition, and judicial vacancy data. For real-time data, the AO maintains federal court statistics tables at uscourts.gov/statistics updated quarterly. For specific case research, PACER's case locator (pcl.uscourts.gov) and per-document access enables detailed investigation of parties, filings, and judicial decisions across all 94 federal district courts, 13 circuit courts of appeals, and specialty courts. The AO also publishes Financial Disclosure Reports for federal judges at uscourts.gov/judges-judgeships/judicial-financial-disclosure-reports — the primary public window into federal judges' financial interests, investments, and outside income.

If you work in federal court administration or are interested in judicial branch employment: The AO manages the human resources, pay, and benefits system for approximately 35,000 federal judicial branch employees across all federal courts — including law clerks, courtroom deputies, probation officers, pretrial services officers, court interpreters, and IT staff. Federal judiciary employees are covered by a separate pay system from the General Schedule (GS) used for executive branch employees; the AO publishes its pay schedule at uscourts.gov/careers/employment. Law clerks — the entry point for many legal careers — are hired through the OSCAR (Online System for Clerkship Application and Review) at oscar.uscourts.gov, which manages applications to most federal judges simultaneously. The Judicial Branch's hiring practices and lateral movement operate differently from the executive branch civil service: there is no centralized application system beyond OSCAR for clerk roles, and each court's clerk's office hires independently. The AO also administers the Federal Judiciary Internship Opportunity Program for law students and college students.

Pending Legislation

  • Free PACER Act: Legislation introduced in multiple Congresses to eliminate fees for accessing federal court documents through PACER — arguing that public access to court records is a fundamental right that should not carry a per-page fee. The AO has opposed elimination of fees on funding grounds. Status: Introduced in the 119th Congress; has not advanced.
  • S 1206 (Sen. Grassley, R-IA) — Judicial Relief Clarification Act of 2025: would require that challenges to federal rules be channeled to specific circuits (primarily the D.C. Circuit), potentially centralizing a significant portion of administrative law appellate work and affecting the AO's caseload management. Status: Introduced.

Recent Developments

  • PACER fee overcharge litigation resolved, free access push continues: The National Veterans Legal Services Program v. United States class action, which alleged PACER fees had been overcharged for years (used for broader IT spending beyond the cost of electronic dissemination), reached a settlement in 2023, resulting in credits and some fee refunds for affected users. Congress has repeatedly introduced the Free PACER Act; proponents argue public access to court records is a constitutional necessity that should not carry a per-page fee. The AO has resisted, arguing fees fund infrastructure that free access would require supplemental appropriations to replace. As of April 2026, the legislation had not passed, but several high-volume legal aid organizations receive fee waivers under the existing waiver program.
  • 2020 judicial network breach prompted major cybersecurity overhaul: In late 2020, the federal courts' document filing system was penetrated in what the Judiciary later acknowledged was a significant breach — likely by foreign state actors — that exposed sealed documents and sensitive case filings. The AO undertook a comprehensive IT security review, implemented enhanced encryption requirements for sealed documents, and worked with the Intelligence Community on attribution and remediation. The breach highlighted the tension between PACER's open-access design (which uses standard web protocols) and the security requirements for sensitive civil and criminal litigation.
  • Defender Services funding remains a perennial budget battleground: The AO's Defender Services division — which funds federal public defenders and CJA panel attorneys — has repeatedly faced underfunding relative to prosecution resources. Budget sequestration in 2013 forced Federal Public Defender offices to furlough staff; subsequent appropriations cycles have been tight. As of FY2026, Defender Services requested approximately $1.5 billion — a fraction of the Department of Justice's budget. The structural asymmetry between well-resourced prosecution and often-understaffed defense is a recurring concern in federal criminal justice policy.
  • Federal court caseload surged from immigration and cryptocurrency cases: AO statistics from 2023–2025 show significant caseload increases in two areas: federal immigration enforcement cases (criminal prosecutions for illegal entry and reentry surged under Trump administration enforcement priorities) and financial crime cases including cryptocurrency fraud and digital asset theft. The immigration caseload increase particularly strained districts along the southern border, where judicial vacancies and caseload pressure compounded. AO data on these trends shapes requests for new judgeships, which Congress authorizes periodically in omnibus bills.
