WASHINGTON, D.C. — Today, the United States Supreme Court rejected Florida’s request to enforce its state immigration law, Senate Bill 4-C.

The law criminalizes the movement of undocumented individuals into the state, attempting to wrest control of the immigration system from the federal government and allow local police officers to make arrests based on immigration status. The result would be inevitable profiling and discrimination–as highlighted by the illegal arrest of a under the provision.

Today’s decision extends a long and unbroken string of defeats that the courts have dealt to SB 4-C and related laws in Texas, Oklahoma, Idaho, and Iowa. This now includes appellate decisions from the Fifth, Eighth, and Eleventh Circuits, as well as the U.S. Supreme Court. The Justices did not provide reasoning, and no Justices noted any dissent.

The federal district court issued a preliminary injunction against the law in April. In response, Florida Attorney General James Uthmeier asked the 11th U.S. Circuit Court to put the order on hold. The unanimous three-judge panel of the 11th Circuit refused, and the Supreme Court has upheld this block as the case continues.

The original challenge was brought on behalf of the Florida Immigrant Coalition, the Farmworker Association of Florida, and several impacted individuals on behalf of a class of all people subject to the law.

“This denial reaffirms a bedrock principle that dates back 150 years: States may not regulate immigration,” said Cody Wofsy, Deputy Director of the Թֱ Immigrants’ Rights Project. “It is past time for states to get the message.”

“This ruling affirms what the Constitution demands — that immigration enforcement is a federal matter and that no one should be stripped of their liberty without due process,” said Bacardi Jackson, Executive Director of the Թֱ of Florida. “Florida’s attempt to bypass federal authority and weaponize local law enforcement to police immigration status was not only unlawful, but it also put thousands of people at risk of unjust detention, separation, and abuse. We are grateful the Court upheld the block, and we remain committed to defending the rights and humanity of all Floridians.”

“Florida’s attempt to wrest control of immigration enforcement from the federal government flies in the face of well-established precedent from the Supreme Court, the Eleventh Circuit, and every other court to have considered a law similar to SB 4-C,” said Paul R. Chavez, Director of Litigation & Advocacy at Americans for Immigrant Justice. “In attempting to adopt its own immigration enforcement regime, Florida’s SB 4-C risked increased racial profiling, civil rights violations, isolation of immigrant communities and unjust deportations. When local policing is entangled with immigration enforcement, it inevitably undermines any trust the local police have built with the immigrant community, which ultimately undermines public safety for all Floridians. Plaintiffs are pleased to see the dominoes continue to fall in holding SB 4-C wholly unconstitutional.”

SB 4-C made it a felony for certain immigrants to enter Florida and mandated pretrial detention without bond. The law created new state crimes that infringed on federal law, as well as the constitutional right to move freely across state lines.

The fight against this illegal state law will continue, and in the meantime the preliminary injunction the Supreme Court left in place today will continue to prevent state authorities from targeting neighbors across Florida with cruel punishments they would not face under federal law.
