HCR2042 is a resolution proposing an amendment to the Arizona Constitution that, pending voter approval, would prohibit the state from using public funds or compelling actions that promote or provide preferential treatment based on race or ethnicity. This amendment aims to ensure equality in public employment, education, and contracting by preventing discrimination or favoritism based on race, sex, color, ethnicity, or national origin. It specifically prohibits the state from requiring individuals to endorse preferential treatment or spending public money on initiatives that promote such practices.

The resolution outlines certain exceptions, allowing for bona fide qualifications based on sex necessary for public operations and actions required to maintain eligibility for federal programs. It also emphasizes that the state cannot mandate training or programs that assign blame based on race or ethnicity, nor can it implement policies that treat individuals differently based on these characteristics. If approved by voters, the amendment will take effect upon the Governor's proclamation and will apply to actions taken after December 14, 2010. The Secretary of State is responsible for submitting this proposition to voters in the next general election.
