Judicial Administration and Improvement Act of 2025
Referred to the House Committee on the Judiciary.
This bill splits the current Ninth Circuit into a smaller "new Ninth" (California, Hawaii, Oregon, Washington, Guam, Northern Mariana Islands) and a new Twelfth Circuit (Alaska, Arizona, Idaho, Montana, Nevada). It reallocates judgeships (new Ninth 21, Twelfth 8), establishes Twelfth court locations, sets rules for assigning current active and senior judges, authorizes temporary additional appointments, and provides transition rules for pending cases.
Progressives see partisan motive; conservatives see administrative reform
Relative to its intended legislative type, this bill is a substantive statutory reorganization of the federal appellate structure that is drafted with considerable operational specificity and concrete amendments to title 28.

It reallocates judgeships (new Ninth 21, Twelfth 8), establishes Twelfth court locations, sets rules for assigning current active and senior judges, authorizes temporary additional appointments, and provides transition rules for pending cases.
The court reorganizing takes effect one year after enactment, with administrative wind‑down two years after the effective date, and authorizes necessary appropriations for implementation.
Technically detailed but politically consequential; requires Senate supermajority-level agreement and executive assent, making enactment unlikely absent broad compromise.

Why the argument around this bill splits.
Progressives see partisan motive; conservatives see administrative reform
Likely skeptical and broadly opposed.
The persona would view the split as having the potential to reshape appellate outcomes and reduce the influence of a historically large, precedent‑setting Ninth Circuit.
Mixed view: acknowledges administrative benefits but worries about motive, cost, and implementation.
Support depends on evidence the split improves efficiency without undermining rule‑of‑law norms.
Likely supportive.
The persona would emphasize restoring local control, reducing dominance of an oversized circuit, and the opportunity to rebalance appellate outcomes in Mountain West and Southwest states.
