The Supreme Court on Wednesday upheld a judicial blockade of Florida's Republican-crafted anti-immigrant law, SB 4-C, signed by Gov. Ron DeSantis, which makes it a crime for undocumented immigrants to enter the state.

The one-sentence court order offered no justification, which is common when judges act in emergency cases. There were no dissents.

The high court justices denied state officials’ request to lift an order by Florida-based District Judge Kathleen Williams barring them from making arrests and prosecutions under the law while a legal challenge in lower courts is resolved.

Judge Williams ruled that the Florida law conflicted with the federal government’s authority over immigration policy.

Florida’s immigration measure, dubbed SB 4-C, was passed by the Republican-controlled state legislature and signed into law by DeSantis.

The law criminalizes undocumented people from entering the state, aiming to wrest control of the immigration system from the federal government and allow local police to make arrests based on immigration status.

The result would be inevitable racial profiling, as evidenced by the unlawful arrest of a U.S. citizen under this measure. provision.

The law, signed by Republican Gov. Ron DeSantis and backed by the Trump administration, made it a felony for some undocumented immigrants to enter Florida, while imposing sentences of pretrial detention without bail.

The Supreme Court, which has handed the Trump administration sweeping victories in its aggressive crackdown on illegal immigration, could consider the broader challenge to the law, which proponents say encroaches on federal power.

“This ruling upholds what the Constitution requires: that immigration enforcement is a federal matter and no one should be deprived of their liberty without due process,” Bacardi Jackson, executive director of the ACLU of Florida, said in a statement following the ruling. U.S. District Judge Kathleen M. Williams ruled in April that the Florida law, passed in February by Gov. Ron DeSantis, likely conflicted with federal immigration laws. An appeals court declined to stay her order. Williams also held Florida Attorney General James Uthmeier in contempt last month after he ordered state law enforcement to enforce the law in defiance of her order. In his appeal, Uthmeier argued that Williams’ order “inflicts irreparable harm on Florida and its ability to protect its citizens from the flood of illegal immigration.” At least six other states have passed similar laws in recent years.

Today's decision extends a long and unbroken series of court defeats against SB 4-C and similar laws like SB 4 in Texas and other state immigration laws in 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 ACLU said in its statement.
