5th Circuit Clears Texas Immigration Arrest Law, Setting Up Appeal

The 5th U.S. Circuit Court of Appeals cleared Texas to enforce Senate Bill 4, a sweeping immigration law that would let state and local officers arrest people suspected of illegally entering the state. The 10-7 ruling on April 24 rested on standing, not the merits, leaving open the central constitutional question: how far Texas can go in doing work that has traditionally belonged to the federal government.

Gov. Greg Abbott signed SB 4 in December 2023 after Republican leaders cast the measure as a response to surging unlawful border crossings. The law would make illegal entry or re-entry into Texas from a foreign country a state crime, authorize state judges to order violators to leave the United States, and impose prison terms of up to 20 years for people who refuse to comply.

The full appeals court overturned a 2024 injunction that had blocked the law after a federal judge in February 2024 halted it. The case then reached the U.S. Supreme Court, which briefly allowed SB 4 to take effect before the 5th Circuit re-blocked it within hours. A divided 5th Circuit panel later upheld the injunction in July 2025, saying the law would interfere with the federal government’s power to enforce immigration law. At the urging of Texas Attorney General Ken Paxton, the full court agreed to reconsider the case.

This time, the majority did not decide whether SB 4 is constitutional. Instead, it said the plaintiffs, Las Americas Immigrant Advocacy Center, American Gateways and El Paso County, did not have authority to bring the challenge. That procedural ruling means the law can move forward in Texas, but it does not settle whether the state can ultimately enforce its own immigration arrest system without colliding with federal authority.

On the ground, the decision could put police officers in Texas communities on the front line of immigration enforcement and force county governments to decide how far they are willing to go in supporting arrests, detention and court orders tied to border crossings. Supporters argue the law is necessary for public safety and border security. Critics say immigration enforcement is the federal government’s job and warn that local agencies could be pulled away from ordinary policing.

Edna Yang, co-executive director of American Gateways, called the ruling “a setback, not the final word.” Christina Sanchez, the El Paso County attorney, said the county was surprised by the decision. Paxton hailed the ruling as a major win, while the case now appears headed toward another Supreme Court fight over the limits of state power at the border.
