Muslim Civil Rights Nonprofits Sue Florida Officials to Prevent Unconstitutional Designation that Threatens the Organizations’ Existence in the State
TALLAHASSE, Fla. — The American Civil Liberties Union, the ACLU of Florida, Southern Poverty Law Center, Akeel & Valentine, PLC, and Bondurant Mixson & Elmore LLP today filed a federal lawsuit challenging Florida officials' imminent and baseless designation of the Council on American-Islamic Relations (CAIR) as a “domestic terrorist organization” under laws that went into effect today.
The challenge comes hours after Gov. Ron DeSantis announced his intent to use the new laws against CAIR, one of America’s leading civil rights organizations. Although the governor did not mention CAIR-Florida, he has previously indicated that he also considers it a “terrorist organization.” If the nonprofits are designated, they face immediate and irreparable harm, including the shuttering of all their operations and advocacy in the state.
In April 2026, Gov. DeSantis signed into law HB 1471 and HB 1473 despite outcry. These laws establish an unprecedented state designation regime and dramatically expand Florida’s authority to both label and punish groups — including nonprofits engaged in First Amendment-protected advocacy — that officials unilaterally decide are security threats. Under the regime, officials can brand nonprofit corporations with debilitating stigma and then use an array of state authorities to immediately silence and incapacitate the organization, its employees, its members, and a wide range of others associated with the group through extraordinarily broad and severe criminal, civil, and administrative penalties.
“We thank the ACLU, SPLC, Akeel & Valentine, and Bondurant for standing up against Gov. DeSantis’ latest attack on the rule of law,” said CAIR’s national headquarters. “Throughout CAIR’s long history, our civil rights organization has worked to protect the Constitution’s guarantees of free speech, religious freedom and equality under the law. We have also pursued justice for all people, including American Muslims impacted by hate. This is exactly why Gov. DeSantis has repeatedly targeted our organization. We see through Gov. DeSantis’ latest biased attempt to punish us for our views and our values. We look forward to fighting these baseless attacks in court and proving once again that the Constitution is stronger than any politician’s bigotry.”
Targeted organizations can receive no meaningful notice and have no meaningful opportunity to challenge the designation before a neutral decisionmaker — and before the designation and harsh penalties take effect.
“Under Florida’s dangerous new regime, the governor and a few officials can play judge, jury, and nonprofit executioner. But the Constitution does not allow elected officials to punish American nonprofits and deny them the fundamentals of due process because of disagreement with their views,” said Hina Shamsi, director of the ACLU’s National Security Project. “Florida’s imminent designation of our clients is both dire and unmoored from reality. CAIR and CAIR-Florida’s speech and advocacy are protected by the First Amendment, which includes their right to criticize the governor, other officials, and their policies. We’re asking the court to protect our clients’ cardinal freedoms.”
As the lawsuit explains, CAIR and CAIR-Florida are nonprofits organized under the laws of the District of Columbia and Florida. They do not engage in “terrorist activity.” Their shared mission, rooted in faith, is to enhance the public’s understanding of Islam, protect civil rights, promote justice, and empower American Muslims. Like other prominent nonprofits, they hold community events, post educational materials on social media, speak about elected leaders, and represent clients in advocacy and civil rights lawsuits. They have not been charged with, let alone convicted of, a crime.
“Like any other faith-driven nonprofit, we host community events to promote religious tolerance and understanding, provide cultural education, and our work seeks to advance public policy that protects the equal treatment of Muslim Americans,” said CAIR-Florida. “Our work is critical to combatting prejudice, false stereotypes, and ensuring the promises of the Constitution cover us all — yet the governor has unfairly labeled us something we are not and threatens our very ability to continue this crucial work. We all share the same rights, and no group should be targeted simply because the governor disagrees with their constitutionally protected speech.”
If the designation goes into effect, its impact will be instant and incapacitating for CAIR and CAIR-Florida’s work in the state. Specifically, the lawsuit claims that they would be caught in a kaleidoscope of criminal prohibitions that would stop them from carrying out even their most basic functions in Florida. Put bluntly, designation will completely shut down their speech, force them to shutter their offices in the state, and brand them with one of the most stigmatizing, infamous labels in our country. On top of the reputational and operational harm, the designation would also violate their right to counsel. That’s because, once designation becomes effective, any lawyer or legal organization that provides or attempts to provide legal services or representation to CAIR or CAIR-Florida faces a credible threat of criminal prosecution under this regime.
“Florida’s attack on the largest Muslim civil rights organization in the country is dangerous and wrong,” said Daniel Tilley, legal director of the ACLU of Florida. “If we allow this undisguised attempt to restrict constitutionally protected speech and association to go unchallenged, it only ensures that the increasingly normalized censorship and discrimination at the hands of our state government will expand ever further.”
The groups are suing under the First Amendment and the due process clause of the Fourteenth Amendment.
“Gov. DeSantis does not have the power to unilaterally brand an organization with this vilifying designation and punish those who support it without due process or judicial review,” said Scott McCoy, deputy legal director, SPLC. “Denying due process and suppressing and punishing constitutionally protected speech and advocacy are clear violations of both the First and Fourteenth Amendments. SPLC will not stand idly by while civil rights groups like CAIR and CAIR-Florida have their rights trampled based on unfounded fear and prejudice by politicians trying to score political points.”
CAIR and CAIR-Florida are also separately suing Florida officials over a related executive order that Gov. DeSantis was trying to use to target the nonprofit. In early March 2026, the U.S. District Court for the Northern District of Florida granted its request for a preliminary injunction blocking enforcement of his “blatantly unconstitutional” executive order, which unilaterally branded CAIR a “terrorist organization,” and would have stripped CAIR — and those associated with the group — of state and local contacts, employment opportunities, funding and other public benefits. The government has since appealed to the Eleventh Circuit Court of Appeals.
