SB14 repealed Colorado's old statutory language that said a marriage is valid only if it is between one man and one woman, removing from state law and instead referring to marriage as a union between two individuals. The bill with the U.S. Supreme Court's 2015 decision in Obergefell v. Hodges, which created a "right" to same-sex "marriage."

The Colorado State Senate passed SB14 on February 5, 2025 by a vote of 29 to 6. We have assigned pluses to the nays because Obergefell itself rests on an illegitimate constitutional foundation. Marriage is not a creature of government, but an institution ordained by God and recognized throughout history as the lifelong union of one man and one woman. The U.S. Constitution contains no authority granting federal courts power to redefine marriage, and under the 10th Amendment, such authority—if it exists at all—is reserved to the states or the people. By codifying Obergefell into state law, SB14 entrenches federal judicial overreach and further divorces civil law from moral and constitutional limits.
