Awad v. Ziriax was a significant 2010 federal lawsuit filed in the U.S. District Court for the Western District of Oklahoma by Muneer Awad, the executive director of the Council on American-Islamic Relations (CAIR)-Oklahoma chapter, along with the American Civil Liberties Union (ACLU) and other plaintiffs, against Oklahoma state officials including Paul Ziriax, Secretary of the Oklahoma State Election Board. The case challenged the constitutionality of Oklahoma State Question 755 (SQ 755), a voter-approved amendment passed on November 2, 2010, with over 70% voter approval, which sought to amend the Oklahoma Constitution to prohibit state courts from considering or applying Sharia law or international law. The plaintiffs argued that SQ 755 violated the First Amendment's Establishment Clause by specifically targeting Islam and discriminating against Muslims, as well as infringing on free exercise of religion. On November 29, 2010, the district court granted a preliminary injunction blocking certification and implementation of SQ 755, citing irreparable harm to religious freedoms. This decision was affirmed by the Tenth Circuit Court of Appeals in 2012, which upheld the injunction on Establishment Clause grounds, noting the amendment's overt religious targeting without a secular purpose. The case was ultimately resolved without the amendment taking effect, reinforcing protections against religiously discriminatory laws. The litigation highlighted tensions between anti-Sharia movements and civil liberties, influenced similar legislative efforts in other states, underscored CAIR's role in advocating for Muslim civil rights, and drew national attention to Islamophobia in American politics amid broader post-9/11 debates on Islam and foreign legal influences.
