If approved by the registered electors of the state of Colorado at the general election on November 6, 2018, the independent congressional redistricting commission (commission) is created in the state constitution and the general assembly's responsibility to divide the state into congressional districts is transferred to the commission. In connection with the creation of the commission:

  • The commission is prohibited from approving a map if it has been drawn for the purpose of protecting one or more members of or candidates for congress or a political party, and current federal law and related existing federal requirements that prohibit maps either drawn for the purpose of or that result in the denial or abridgement of a person's right to vote or electoral influence on account of a person's race, ethnic origin, or membership in a protected language group are codified;
  • At least 8 of the 12 commissioners, including at least 2 of the commissioners who are not registered with any political party, are required to approve a redistricting map, and the date by which a final map must be approved is specified;
  • Nonpartisan staff draft a preliminary redistricting map and up to 3 additional maps, and, in the event of deadlock by the commission, a process is created by which nonpartisan staff submit a final map to the Supreme Court for review based on specified criteria; and
  • Judicial review of a commission-approved or nonpartisan-staff-submitted redistricting map is authorized, and the Supreme Court review is limited to whether the commission or the staff committed an abuse of discretion.
