Which landmark decision affected the recognition of same-sex marriage in Arizona?

The landmark decision that significantly affected the recognition of same-sex marriage in Arizona is Obergefell v. Hodges. This ruling, issued by the U.S. Supreme Court in June 2015, established that same-sex marriage is a constitutional right under the Fourteenth Amendment, which guarantees equal protection and due process rights to all individuals. The Court's decision effectively legalized same-sex marriage nationwide, nullifying state laws that prohibited it.

Prior to this decision, states, including Arizona, had various laws and constitutional amendments that restricted marriage to opposite-sex couples. Obergefell v. Hodges directly impacted those laws, including Arizona's, and led to the immediate recognition of same-sex marriages in the state and across the country. Thus, it serves as a crucial milestone in the pursuit of marriage equality. The other listed cases—Roe v. Wade, Brown v. Board of Education, and Loving v. Virginia—address different aspects of civil rights and marriage but do not specifically pertain to the recognition of same-sex marriage.
