A federal appeals court on Friday handed Texas a significant legal win, lifting a lower court injunction that had blocked key provisions of Senate Bill 4, the state law that makes illegal entry into Texas a state crime and empowers local police to arrest suspected border crossers. The U.S. Court of Appeals for the Fifth Circuit issued a brief order pausing the preliminary injunction that U.S. District Judge David Alan Ezra had imposed just two weeks earlier, clearing the way for full enforcement of the contested statute.
The ruling means Texas law enforcement can now arrest individuals suspected of crossing the border illegally, including, under one provision, people who hold green cards or other lawful federal immigration status but who re-entered the country without authorization. State magistrates may also issue removal orders and prosecute those who refuse to comply.
Governor Greg Abbott wasted no time framing the decision. He posted on X shortly after the order came down, calling it a "major border security victory."
"We will keep fighting in the courts, working with President Trump, and doing everything necessary to secure our border and protect Texans."
One judge on the Fifth Circuit panel disagreed. Judge Leslie Southwick dissented, and would have denied the state's motion to stay the injunction. The court did not publish detailed reasoning for its decision.
Senate Bill 4 is no modest tweak to state law. It creates a suite of enforcement tools that push Texas directly into territory long claimed as exclusively federal. Four provisions stood at the center of the legal fight.
First, the law treats reentry into the United States as a state criminal offense, even for individuals who currently hold green cards or other lawful federal immigration status. Second, it grants Texas state magistrates authority to issue removal orders. Third, it creates a separate offense for refusing to obey those removal orders. Fourth, it requires magistrates to continue prosecution of defendants even when a federal immigration case is already pending.
That last provision is particularly notable. It means Texas courts would not defer to federal proceedings, a direct challenge to the traditional framework in which the federal government controls immigration enforcement and adjudication. The ACLU, ACLU of Texas, and Texas Civil Rights Project filed a class-action lawsuit on May 4 contending that SB 4 strips the federal government of its exclusive authority over immigration. The groups described the law as among the harshest immigration statutes any state legislature has enacted.
The broader fight over how far states can go in enforcing immigration law has played out across multiple courts and agencies. A recent unanimous Supreme Court ruling on asylum review standards underscored the judiciary's active role in shaping the boundaries of federal immigration authority.
Judge David Alan Ezra, a U.S. District Court judge, issued a 78-page opinion on May 14 granting a preliminary injunction against the reentry-related provisions of SB 4. His opinion determined that the two unnamed Honduran immigrants who led the class-action suit faced likely arrest and possible removal once the reentry provisions took force.
But Ezra's order was narrow. He blocked only the reentry sections. The rest of the statute, provisions that did not directly involve the reentry offense or magistrate removal authority, began enforcement the very next day, May 15.
That partial enforcement created an unusual legal landscape. Texas police could enforce some parts of SB 4 but not others, depending on which provisions Ezra had left standing. The Fifth Circuit's Friday order collapsed that distinction. All four contested provisions are now enforceable while the case continues through the appeals process.
The speed of the appellate turnaround is worth noting. The ACLU and its partners filed suit on May 4. Ezra issued his injunction ten days later, on May 14. Fifteen days after that, the Fifth Circuit stayed the injunction. The entire sequence, from lawsuit to appellate override, took less than a month.
Texas has been at the forefront of states asserting their own authority on immigration enforcement, particularly under Governor Abbott. SB 4 represents the most aggressive legislative effort yet, but it sits within a broader pattern of state officials stepping into roles the federal government has either declined to fill or struggled to execute.
The Trump administration has signaled its own commitment to tougher enforcement through personnel decisions. The appointment of ICE veteran David Venturella to lead the agency reflected that priority at the federal level. But SB 4 goes further than federal cooperation, it creates an independent state enforcement mechanism that operates alongside, and in some cases regardless of, federal proceedings.
The provision requiring Texas magistrates to continue prosecution even when a federal immigration case is pending makes the point plainly. Texas is not waiting for Washington. It is building a parallel track.
Critics, led by the ACLU, argue that this parallel track violates the constitutional framework. Immigration enforcement, they contend, belongs to the federal government. Allowing fifty states to create their own immigration crimes and removal procedures would produce chaos.
Supporters counter that the federal government's failure to secure the border left states no choice. Abbott's post-ruling statement made that case in shorthand: fight in the courts, work with the president, do "everything necessary."
The appellate order was notably spare. The Fifth Circuit panel issued a brief order with no detailed reasoning beyond pausing the lower court's block. That means the legal questions at the heart of SB 4, whether a state can criminalize reentry, whether state magistrates can issue removal orders, whether state prosecution can proceed alongside federal immigration cases, remain unresolved on the merits.
The stay keeps SB 4 alive while the appeal moves forward. It does not settle whether the law will ultimately survive constitutional scrutiny. Judge Southwick's lone dissent signals that the panel was not unanimous, but the reasoning behind his objection was not detailed in the order.
The composition of the full panel, beyond Southwick, was not disclosed in the reporting. Nor is it clear when the Fifth Circuit will hear the case on the merits, or whether the plaintiffs will seek emergency relief from the Supreme Court. Justice Clarence Thomas has previously rebuked the high court for declining to take up state-level immigration disputes, suggesting at least some appetite on the bench for resolving these questions.
The two unnamed Honduran immigrants at the center of the class-action suit now face a changed legal reality. Judge Ezra's 78-page opinion found they were likely to be arrested and possibly removed once the reentry provisions took effect. With those provisions now enforceable, the risk Ezra identified is no longer hypothetical.
The ACLU and its partners have framed SB 4 as a threat not just to illegal immigrants but to lawful permanent residents. The provision treating reentry as a state crime "even for people now holding green cards or other lawful federal status" extends the law's reach well beyond the typical target of border enforcement.
That distinction matters. A green card holder who left the country and returned, perhaps to visit family, could face state criminal charges under SB 4 if Texas authorities determined the reentry was unauthorized. The federal government might disagree with that characterization entirely, but under the law's fourth provision, the state prosecution would continue regardless.
The Trump administration's broader enforcement posture has included actions against individuals with legal status as well. Secretary Rubio's revocation of green cards in a high-profile case demonstrated the administration's willingness to use existing federal tools aggressively. SB 4 adds a state-level layer on top of that federal framework.
The legal battle over SB 4 is far from over. The Fifth Circuit's stay is a procedural win for Texas, not a final ruling. The merits of the constitutional challenge, whether states can create their own immigration crimes and removal systems, will be litigated in the months ahead.
Meanwhile, enforcement is live. Texas police can arrest suspected illegal border crossers under state law. State magistrates can order removals. And the federal government's traditional monopoly on immigration enforcement has, at least for now, a significant new competitor.
The internal dynamics of federal enforcement continue to shift as well. Recent leadership changes within ICE's interior enforcement operations reflect an agency in transition, even as states like Texas build their own enforcement infrastructure.
For years, border-state governors complained that Washington refused to act. Texas decided to stop waiting. A federal appeals court just told them they can keep going, for now.
