HCR 2027 is a resolution proposing an amendment to the Arizona Constitution that would establish designated seats "A" and "B" for candidates running for the House of Representatives in each legislative district. This change would take effect with the inauguration of the Fifty-seventh Legislature in 2025, requiring candidates to run for and be elected from either seat. The resolution mandates that the Secretary of State submit this proposition to voters during the next general election, and it will become effective only if approved by the voters and proclaimed by the Governor.

The resolution also outlines the structure and responsibilities of an independent redistricting commission, which will be responsible for establishing congressional and legislative districts. The commission will consist of five members, ensuring political balance and fairness in its composition. It will operate under specific guidelines to create districts that comply with constitutional requirements, maintain equal population, and respect communities of interest. The commission will have the authority to hire staff, manage resources, and engage in legal actions related to redistricting, with its duties expiring upon the appointment of the next commission.
