HB634 splits the Ninth Circuit, creates a new Twelfth Circuit, and adds judgeships

The bill divides the sprawling Ninth Circuit into two circuits, authorizes new permanent and temporary judgeships, and lays out transfer, staffing, and administrative rules—changing appellate geography and capacity.

The Brief

HB634 (Ninth Circuit Court of Appeals Judgeship and Reorganization Act of 2025) amends title 28 to divide the current Ninth Judicial Circuit into a smaller “new ninth circuit” (California, Guam, Hawaii, Northern Mariana Islands) and a newly created Twelfth Circuit (Alaska, Arizona, Idaho, Montana, Nevada, Oregon, Washington). The bill adjusts statutory circuit counts, sets locations for court sittings, and authorizes both permanent and temporary additional circuit judges across the reorganized circuits.

Beyond adding seats, the bill prescribes how sitting Ninth Circuit judges will be assigned by official duty station, preserves seniority, provides detailed rules for transfer of pending appeals and rehearing petitions, creates procedures for temporary inter-circuit designations of circuit and district judges, allows joint administrative functions between contiguous circuits, and ties the effective date to a Senate-confirmation trigger. For practitioners, courts, and litigants in the affected states and territories, HB634 remaps appellate governance, alters likely en banc and panel rosters, and creates short- and long-term staffing and logistical changes for the federal appellate system.

At a Glance

What It Does

Splits the current Ninth Circuit into two circuits (a smaller Ninth and a new Twelfth), amends statutory tables for circuit numbers and judges, designates official court locations, and authorizes a mix of permanent and temporary judgeships with assignment rules tied to judges’ duty stations.

Who It Affects

Federal circuit and district judges in the former Ninth Circuit, appellate litigators and law firms practicing in the affected states/territories, the Administrative Office of the U.S. Courts and court clerks, the Department of Justice (appellate division), and parties with appeals pending in the Ninth Circuit when the split occurs.

Why It Matters

The bill restructures appellate geography that has governed West Coast federal appeals for decades, changing where and how panels are formed, altering the distribution of judicial workload, prompting new confirmations, and creating administrative and precedent-management challenges that will affect case outcomes and court operations.

What This Bill Actually Does

HB634 replaces the single, large Ninth Circuit with two distinct circuits. The text defines three terms—former ninth circuit (the Ninth as of the day before the law’s effective date), new ninth circuit (California plus Pacific territories), and twelfth circuit (seven northwestern states).

It edits the statutory circuit table to add a fourteenth listing and inserts the Twelfth Circuit after the Eleventh.

The bill authorizes new judgeships in several buckets. It requires the President, with Senate advice and consent, to appoint two additional circuit judges for the former Ninth Circuit (with official duty stations limited to Arizona, California, or Nevada) and to appoint three judges for the new Ninth (with a prohibition on appointment before January 21, 2025).

It also creates two temporary judgeships for the former Ninth Circuit; those temporary seats are subject to a 10-year vacancy-sunset rule tied to when certain vacancies occur on the new Ninth. Section 5 updates the numeric allotment of judges per circuit in the statutory table (showing the Ninth at 25 and the Twelfth at 9).For sitting judges, the bill assigns active judges of the former Ninth to one of the two new circuits based on their official duty station the day before the effective date: judges whose duty stations are in California, Guam, Hawaii, or the Northern Mariana Islands become judges of the new Ninth; those with duty stations in Alaska, Arizona, Idaho, Montana, Nevada, Oregon, or Washington become Twelfth Circuit judges.

Senior judges may elect which of the two circuits they join. The law preserves each judge’s seniority from the date of their original commission as a Ninth Circuit judge.HB634 also contains transition mechanics for cases and procedures.

Appeals already submitted for decision stay with the same proceedings as if the Act had not passed; appeals not yet submitted are transferred to the court where they would have been heard if the Act had been in effect at filing. Petitions for rehearing (including en banc petitions) that were filed or decided around the effective date are treated largely as if the Act had not been enacted, and if rehearing en banc is granted the composition of the rehearing follows the pre-split composition rules.Operationally, the bill sets official places for court sittings (Honolulu, San Francisco, Pasadena for the new Ninth; Phoenix, Seattle for the Twelfth), authorizes temporary designations of circuit and district judges between the two circuits on request of chief judges, and permits contiguous circuits to jointly carry out administrative functions.

The statute ties the effective date to a confirmation trigger: the Act takes effect on the first day of the first fiscal year beginning after the nine-month period that starts when five judges authorized under section 4 are confirmed. The existing Ninth Circuit may take administrative steps to implement the split and ceases to exist for administrative purposes two years after the effective date.

The Five Things You Need to Know

1

The bill creates a new Twelfth Circuit composed of Alaska, Arizona, Idaho, Montana, Nevada, Oregon, and Washington and reassigns California plus Pacific territories to a smaller new Ninth Circuit.

2

Statutory judge counts change: the amended section 44(a) lists the Ninth Circuit with 25 judges and the new Twelfth Circuit with 9 judges.

3

The President must appoint 2 additional circuit judges for the former Ninth Circuit, 3 circuit judges for the new Ninth (not before Jan 21, 2025), and 2 temporary circuit judges for the former Ninth Circuit; temporary seats carry a 10‑year vacancy nonfill rule tied to the new Ninth.

4

Assignments of sitting Ninth Circuit judges occur by official duty station the day before the effective date; senior judges may elect which new circuit to join, and all judges’ seniority runs from their original Ninth Circuit commission date.

5

The Act’s effective date is delayed: it begins on the first day of the fiscal year following the 9‑month period that starts when five of the judges authorized in section 4 have been confirmed by the Senate.

Section 3

Redefines circuit table and creates the Twelfth Circuit

Section 3 amends 28 U.S.C. §41 by increasing the numbered count of circuits and replacing the single Ninth Circuit line with two entries: a new Ninth listing (California and the Pacific territories) and an inserted Twelfth listing (the seven northwestern states). Practically, this is the statute’s re-mapping step: it changes the legal geography that determines which circuit hears appeals from which districts and is the foundational statutory change that triggers all downstream reassignments and rules.

Section 4

Authorizes permanent and temporary judgeships and sets duty‑station rules

Section 4 breaks judgeship authorizations into three buckets—permanent additions for the former Ninth, permanent additions for the new Ninth (with a prohibition on appointments before a specified date), and temporary additions for the former Ninth. It also restricts the official duty stations for the new appointees to specific states (Arizona, California, Nevada for some appointments) and includes a vacancy-sunset rule that prevents refilling certain positions after a ten‑year mark. This section creates timing and staffing complexity: some seats are immediately available, others are delayed, and temporary seats have rules that will automatically reduce the total number of active judges after a statutory period.

Section 5–6

Updates numeric judge allotments and court sitting locations

Section 5 adjusts the judges-per-circuit table (making the Ninth 25 and the Twelfth 9). Section 6 amends the list of places of holding court—naming Honolulu, San Francisco, Pasadena for the new Ninth and Phoenix, Seattle for the Twelfth. These are operational levers: they hint at where panels and administrative centers will concentrate, affect travel burdens and local access, and guide future facility and budget planning under the appropriation authorization.

Section 7–9

Assigns current judges, preserves seniority, allows senior-judge elections

Section 7 assigns active judges of the former Ninth to one of the two new circuits based on their official duty station the day before the effective date, and includes a ‘least senior in commission’ rule to correct for any statutory over-allocation that would otherwise exceed authorized numbers. Section 8 gives senior judges an affirmative election right to choose which circuit they join. Section 9 preserves each judge’s seniority from their original Ninth commission date. Together, these provisions determine panel composition, transfer of judicial experience between circuits, and initial balance of judges across the two courts.

Section 10

Translates pending appeals and rehearing petitions across the split

Section 10 creates clear rules for handling pending matters: appeals already submitted remain with their current proceedings; appeals not submitted are transferred to the circuit where they would have been heard if the Act had been in force at filing; and rehearing petitions filed or decided around the effective date are treated as though the Act had not been enacted, with rehearings en banc conducted by the pre‑split composition if granted. This reduces immediate procedural uncertainty but requires clerks to make large-scale certified transfers of records.

Section 11–13

Temporary judge designations and administrative coordination

Sections 11 and 12 amend 28 U.S.C. §§291–292 to allow chief judges of the new Ninth and Twelfth circuits to designate judges to sit temporarily in the other circuit, and to request district judges to sit on courts of appeals when business so requires. Section 13 allows contiguous circuits to jointly perform administrative functions. These are practical tools to manage workload spikes and to maintain continuity—especially important during the early transition years—while preserving each court’s procedural rules for designated judges.

Section 14–15

Transition authority and effective date trigger

Section 14 authorizes the existing Ninth Circuit to take administrative steps to implement the Act and provides that it ceases to exist for administrative purposes two years after the Act’s effective date. Section 15 ties the Act’s effective date to a Senate-confirmation benchmark: the first day of the first fiscal year starting after the nine‑month period that begins when five of the judges authorized in section 4 have been confirmed. This sequencing gives Congress and the Judiciary a measure of flexibility but also creates a conditional, indeterminate start date that depends on the confirmation calendar.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Appellate litigants in certain states and territories: Reduced travel distances and potentially faster case processing where new circuit seats and court locations (Phoenix, Seattle, San Francisco, Pasadena, Honolulu) localize panels.
  • Federal judges and judicial staff in high‑caseload districts: Additional judgeships relieve docket pressure and can reduce individual judge workloads and backlog in crowded districts within the former Ninth Circuit.
  • Law firms and local bar associations in the reconstituted circuits: New local circuit seats and facilities create business for appellate practitioners and local infrastructure (case filings, oral arguments, and local clerk interactions).
  • Administrative Office of the U.S. Courts: Gains clearer statutory authority to coordinate administrative consolidation between contiguous circuits and to deploy judges temporarily to balance panels during the transition.

Who Bears the Cost

  • U.S. Courts and taxpayers: New permanent and temporary judgeships, plus facility and staffing needs (authorized appropriations), will require additional federal funding and capital outlays for courthouses and clerk offices.
  • Department of Justice and federal appellate litigators: Transitioning briefs, transferring records, and reassigning counsel strategies to new circuits create immediate logistic and strategic costs for pending and future appeals.
  • Sitting Ninth Circuit judges and clerks: Judges reassigned by duty station may face forced transfers of institutional work, shifts in regional legal cultures, and potential changes in en banc dynamics; clerks must manage large record transfers and retool case triage practices.
  • Senate and White House: The need to confirm multiple nominees to fill authorized seats creates political, calendar, and resource costs for nominations and confirmations (and affects how quickly the reorganization fully takes effect).

Key Issues

The Core Tension

The central dilemma is efficiency versus uniformity: the bill aims to reduce travel and caseload pressure by localizing appellate review and adding judges, but splitting a large circuit risks greater divergence in federal appellate law, creates administrative overhead and transitional uncertainty, and forces trade-offs between short‑term relief and the long‑term coherence of precedent across the western United States.

The bill balances a prospective operational improvement—smaller, regionally focused circuits—against significant transitional frictions. The duty‑station assignment rule is administratively tidy but can produce awkward outcomes: a judge with an appointment and caseload tied to one state could be reassigned simply because their official duty station sits on the other side of a statutory line, creating potential mismatches between expertise and circuit needs.

The ‘least senior in commission’ swap to correct statutory over-allocation protects numeric limits but may leave pockets of institutional expertise concentrated in one court or the other.

The effective‑date trigger (dependent on confirmation of five judges and a subsequent nine‑month window) introduces meaningful uncertainty for courts, litigants, and budget planners. Because pending appeals are transferred only if not yet ‘submitted for decision,’ litigants and clerks will need precise cutoffs and substantial logistics to move printed records and dockets.

The temporary judgeships and the 10‑year nonfill rule create a rolling staffing plan that may raise questions about long‑term capacity: temporary seats planned to sunset could leave the Twelfth Circuit short if caseload projections shift. Finally, permitting joint administrative functions leaves open the scope of consolidation—cost-saving opportunities exist, but so do risks of under-resourcing one circuit in favor of centralized functions that may not match local needs.
