HCR2042 is a resolution aimed at amending the Arizona Constitution to prohibit the state from using public funds or compelling actions that promote or provide preferential treatment based on race or ethnicity, pending voter approval. This amendment seeks to ensure that no individual or group is discriminated against or favored due to their race, sex, color, ethnicity, or national origin in areas such as public employment, education, and contracts. It specifically prohibits actions like requiring individuals to endorse preferential treatment as a condition for opportunities in hiring or educational admissions.

The resolution also clarifies that while it prohibits preferential treatment, it does not prevent legitimate qualifications based on sex necessary for public operations, nor does it invalidate existing court orders or consent decrees. It allows for certain actions needed to maintain eligibility for federal programs, as long as they do not change application criteria. The Secretary of State is responsible for submitting this proposition to voters in the next general election, and the amendment will only take effect if approved by the electorate and proclaimed by the Governor.
