The suit, which was filed on Aug. 3, alleges the denial violated the U.S. Constitution, the federal Religious Land Use and Institutionalized Persons Act, and Oklahoma law by discriminating against Muslims.

The city of Broken Arrow said in an email to The Epoch Times that it does not comment on lawsuits. The city acknowledged on July 28 that the U.S. Department of Justice had started an investigation into the matter.

"The City Council and Administration are fully engaged with the DOJ in its investigation," the city stated, adding it would have no further comment.

The DOJ's Civil Rights Division is investigating whether Broken Arrow violated the Religious Land Use and Institutionalized Persons Act after denying the rezoning application for the Islamic Society of Tulsa.

According to the complaint, the Islamic Society of Tulsa bought about 15 acres of land in Broken Arrow in 2014 with the intention of building a mosque, a community center, and a small commercial development.

City planning staff concluded the proposal complied with the city's comprehensive plan and recommended approval. The Broken Arrow Planning Commission also voted to recommend approval after a lengthy public hearing.

The lawsuit claims the proposal was rejected by the City Council after "a wave of bigoted opposition from members of the community and local politicians."

Despite recommendations from city staff and the Planning Commission, the City Council voted 4–1 on Jan. 12 to deny both the rezoning request and the conditional use permit.

The lawsuit further alleges the city approved similar rezoning and permitting requests for Christian churches and commercial developments while allowing those applicants to address traffic and engineering issues later in the approval process.

The complaint seeks a court order allowing the project to proceed, a declaration that the city's actions were unlawful, and monetary damages including attorneys' fees.

It also notes the DOJ's investigation into whether the city violated federal religious land-use protections.

Oklahoma Attorney General Gentner Drummond is asking the Trump administration to halt the DOJ investigation.

In a letter to President Donald Trump and acting U.S. Attorney General Todd Blanche, Drummond called the investigation "federal overreach" and said land-use decisions should be left to state and local officials.

Drummond also asked the DOJ to withdraw requests for records involving private citizens, require senior-level approval for any further investigative steps, and coordinate with the Oklahoma Attorney General's Office before taking additional action against Oklahoma municipalities.
