America’s Largest Muslim Rights Group Shuts Down in Florida After ‘Terrorist’ Designation

The largest Muslim civil rights organisation in the United States has shut down its operations in Florida after the state government labelled it a “domestic terrorist organisation” under a new and untested law.

The Council on American-Islamic Relations, known as CAIR, suspended all of its work in Florida this week after a federal judge refused to block the designation. The group says the label is baseless and unconstitutional. Florida’s governor and attorney general say the law is working exactly as intended.

The case is now heading to an appeal, and legal experts say it could set a precedent for how far American states can go in labelling advocacy groups as terrorists — without charging them with any crime.

What happened this week

On Wednesday, 4 November, a bright orange notice appeared on the front door of CAIR-Florida’s headquarters in Temple Terrace, near Tampa. It read: “We have suspended our operations in Florida because of Governor Ron DeSantis and other state officials’ baseless and unconstitutional enforcement of the state’s unprecedented new ‘domestic terrorist organization’ laws against us.”

The same message was posted on the group’s website, which now carries little else. CAIR-Florida also paused recurring donations on its platforms and urged supporters to cancel automatic payments before 5 November. It told Florida residents not to join its mailing lists or otherwise engage with the organisation.

The shutdown followed a court ruling late on Wednesday night. Chief US District Judge Allen C. Winsor, of the Northern District of Florida, denied CAIR’s request to stop the designation from taking effect. The designation itself came into force on Thursday, 5 November.

CAIR says it will appeal the ruling. It is represented by the American Civil Liberties Union (ACLU), the ACLU of Florida, the Southern Poverty Law Center, and the law firm Bondurant Mixson & Elmore.

The law behind the designation

The designation was made under a new Florida law, HB 1471, which Governor Ron DeSantis signed in April 2026. The law took effect on 1 July.

HB 1471 gives five Florida executive officials — the governor, the cabinet and the state’s chief of domestic security — the power to designate groups as “domestic terrorist organisations”. What makes the law unusual, and controversial, is what it does not require.

According to the ACLU, the officials can designate and penalise a group without filing charges, starting court proceedings, proving their case beyond a reasonable doubt, putting the case before a jury, or following the other constitutional protections that normally apply in the criminal justice system.

In other words, the government can label a group a terrorist organisation through an administrative decision, not through a trial.

On 29 September, DeSantis and the Florida Cabinet voted to designate more than 90 groups under the law, including CAIR and its Florida chapter. The designations were scheduled to take effect on 5 November, about a month after the groups were given notice.

What the judge decided

CAIR and CAIR-Florida went to court in October, asking a federal judge to intervene before the designation took effect. They argued that the designations under HB 1471 violated their rights to due process and free speech under the US Constitution.

On Wednesday night, Judge Winsor denied their request for emergency relief. He wrote that the plaintiffs were unlikely to succeed at this stage on their claims that the designations violated their due process and First Amendment rights.

But the ruling was not a complete win for the state. The judge also issued a narrow form of preliminary relief: he held that Florida prosecutors cannot enforce the law’s penalties against CAIR, its employees, or third parties in connection with the provision of legal services to the groups.

The ruling does not resolve the case. It does not address all of CAIR’s claims, and it makes no factual findings about Florida officials’ allegations against the groups — allegations CAIR maintains are baseless. The case will continue, and CAIR has said it will appeal the denial of emergency relief.

Florida’s leaders celebrated the ruling. Attorney General James Uthmeier wrote on X on Thursday: “This morning, a federal court upheld Florida’s Domestic Terrorist Organization law and rejected CAIR’s attempt to stop the designations.”

What CAIR says

CAIR has been blunt in its response. Hiba Rahim, who was executive director of CAIR-Florida until it shut down on Wednesday, said the group “categorically rejects Florida officials’ baseless designation.”

The group’s position is simple: it is a civil rights organisation, not a terrorist group, and the designation is a political attack on its advocacy work. CAIR says the law is being used to punish it for its views, including its criticism of the federal government’s crackdown on immigration and on pro-Palestinian protests.

CAIR is the largest Muslim civil rights organisation in the United States. Its work includes providing legal services to Muslim Americans, advocating for civil rights, and documenting hate crimes and discrimination against Muslims. According to Reuters, CAIR blames the Republican-led federal crackdown on immigration and pro-Palestinian protests for a rise in Islamophobia in the country.

For the people who relied on CAIR-Florida, the shutdown has immediate effects. The group’s advocacy and legal services in the state are now suspended while the appeal moves forward. That means Muslim Floridians who turned to CAIR for help with discrimination complaints, workplace issues or immigration problems have lost one of their main sources of support.

What Florida says

Florida officials tell a very different story. Governor DeSantis has argued that the state needs strong tools to deal with extremist groups, and that the designation power is a legitimate part of keeping Florida safe.

The state has not publicly presented detailed evidence against CAIR in the court case so far, and the judge’s ruling made no findings about the truth of the state’s allegations. But Florida’s leaders have treated the court’s refusal to block the designation as a vindication of the law.

The attorney general’s office has also pointed out that Florida is not the first state to take this step. Texas had previously designated CAIR under its own state terrorism laws, according to reports this week.

Supporters of the law say states should be able to act quickly against groups they believe are dangerous, without waiting for a long criminal trial. Critics say that is exactly the problem: the law lets politicians label their critics as terrorists without having to prove anything.

Why this case matters beyond Florida

This is not just a dispute about one organisation in one state. The case raises questions that go to the heart of free speech in America.

The First Amendment to the US Constitution protects freedom of speech and freedom of association. That means Americans have the right to hold unpopular views, to join groups the government dislikes, and to criticise the government — without being punished for it.

CAIR’s lawyers argue that HB 1471 breaks that promise. They say the law lets a small group of politicians shut down an advocacy organisation simply by labelling it, with no trial and no proof. If that is allowed, they argue, any group could be next — a charity, a protest movement, a religious organisation, or a political campaign.

The ACLU has made the same point in broader terms. Under HB 1471, it says, five executive officials have the power to “designate and debilitate” US groups — including nonprofits engaged in advocacy protected by the First Amendment — without any of the protections the Constitution normally requires.

On the other side, Florida officials and supporters of the law argue that the government must be able to act against groups it considers a threat, and that the courts can sort out mistakes later. They say the designation is a security measure, not a punishment for speech.

The appeal will test which of these views the higher courts accept. Because the law is new and has no precedent, whatever the appeal court decides could shape similar laws in other states. Texas has already moved in the same direction, and other states are watching.

The wider picture

The Florida case is part of a larger pattern in American politics. In recent years, several states have passed laws that give officials new powers over protest groups, advocacy organisations and nonprofits.

At the same time, the federal government has cracked down on immigration enforcement and on pro-Palestinian campus protests, moves that CAIR and other civil rights groups say have fuelled a rise in anti-Muslim sentiment.

CAIR says its own work documenting that rise is one reason it has been targeted. Florida officials have not accepted that argument, and the court has not ruled on it.

What is clear is that the dispute is far from over. The appeal will take months, and the case could eventually reach higher courts. Until then, CAIR-Florida remains closed, its staff are out of work, and the Floridians who depended on its services must look elsewhere for help.

What happens next

The immediate next step is CAIR’s appeal against Judge Winsor’s refusal to block the designation. The appeal will ask a higher court to look again at whether HB 1471 violates the Constitution.

At the same time, the main lawsuit continues in the federal court in Florida. That case will examine CAIR’s claims in full, including whether the designation process denies the group due process and punishes it for protected speech.

The narrow relief the judge did grant — protecting the provision of legal services from prosecution — will also matter. It means lawyers can still work with CAIR without fear of being punished under the law, which keeps the group’s legal defence alive.

Beyond the courts, the case will be watched by lawmakers in other states. If Florida’s law survives, more states may copy it. If it is struck down, it will serve as a warning about the limits of state power over advocacy groups.

For now, the notice stays on the door of CAIR’s Tampa office, and the organisation that once helped thousands of Muslim Floridians is silent in the state where it operated for years.

Frequently asked questions

What is CAIR?

The Council on American-Islamic Relations (CAIR) is the largest Muslim civil rights organisation in the United States. It provides legal services, advocates for civil rights, and documents hate crimes and discrimination against Muslim Americans.

Why did CAIR shut down in Florida?

Florida designated CAIR and CAIR-Florida as “domestic terrorist organisations” under a new state law, HB 1471. The designation took effect on 5 November 2026, after a federal judge refused to block it. CAIR says the designation is baseless and unconstitutional, and it suspended operations rather than operate under the label.

What is HB 1471?

HB 1471 is a Florida law signed by Governor Ron DeSantis in April 2026. It gives the governor, the cabinet and the chief of domestic security the power to designate groups as domestic terrorist organisations. Critics say it allows this without charges, a trial, or proof beyond a reasonable doubt.

What did the judge decide?

Chief US District Judge Allen C. Winsor denied CAIR’s request to stop the designation, saying the group was unlikely to succeed at this stage on its constitutional claims. However, he also ruled that prosecutors cannot punish people for providing legal services to CAIR. The case is not over, and CAIR is appealing.

Has any other state done this?

Yes. Texas had previously designated CAIR under its own state terrorism laws, according to reports this week.

What happens next?

CAIR will appeal the judge’s ruling, and the main lawsuit continues in federal court. The outcome could set a precedent for similar laws in other states.

Conclusion

The shutdown of CAIR in Florida is a small story about one office in Tampa — and a big story about the limits of government power in America.

A state government has used a new law to label the country’s largest Muslim civil rights group a terrorist organisation, without a trial and without publicly proving its case. A federal judge has, for now, allowed the designation to stand. The group has closed its doors, stopped taking donations, and told its supporters to stay away.

Whether that is a legitimate security measure or an attack on free speech is now a question for the appeal courts. Their answer will matter far beyond Florida — for every advocacy group, charity and protest movement that depends on the right to speak freely without fear of being labelled a terrorist for doing so.
