Redistricting Reform Act of 2025

Requires most States to adopt congressional district maps drawn by an independent redistricting commission (or by a three-judge federal court if a commission plan is not enacted). It sets detailed, ranked map-drawing rules (equal population, Voting Rights Act compliance, compactness, respect for political subdivisions, and a ban on maps that materially favor a political party), requires public notice and hearings, creates deadlines, and gives federal courts authority to step in and impose maps when States fail to act or violate the rules.

Establishes procedures for how commissions must prepare and approve maps, how the Department of Justice reviews maps, how citizens can ask courts to draw maps, and what remedies courts can order (including interim or replacement plans). The law also provides administrative rules and federal payments to support State redistricting, defines who can sue, limits certain privileges, and sets rules for judicial handling of redistricting cases.
