Redistricting commission

[2] Of these 21 states, 13 use redistricting commissions to exclusively draw electoral district boundaries (see below).

[3] For purposes of these tables: Iowa is a special case: Additionally, Maine and Vermont use advisory committees for redistricting.

[22] Citizens can apply, and the Secretary of State picks 200 at random, with party and geographic diversity.

Republican and Democratic leaders in the Michigan House and Senate can each reject five names, up to 20 in total.

The legislature is still allowed to propose maps, but the commission retains the right to review them, and voters could sue to block the implementation of a plan in violation of Prop 4's requirements.

Should that commission be unable to reach an agreement, the legislature resumes control of the process, but will have lower thresholds for passing a plan (albeit with stricter rules).
