The U.S. Court of Appeals for the Fifth Circuit handed Texas a major legal win Friday, issuing an order that clears the state to enforce its contested immigration statute, Senate Bill 4, including provisions that let Texas police arrest people suspected of crossing the border illegally. The ruling pauses a preliminary injunction that had blocked the law's most aggressive sections just two weeks earlier.
The brief appellate order provided no detailed reasoning. But its practical effect is immediate: Texas law enforcement can now treat illegal border crossings as a state crime, and state magistrates can issue removal orders, authority that until now belonged exclusively to the federal government.
Governor Greg Abbott wasted no time claiming the victory. In a post on X, Abbott tied the ruling directly to his own legal intervention and to the broader partnership between Texas and the Trump administration on border security.
The law goes well beyond giving local cops new arrest powers. As the Daily Caller reported, SB 4 treats reentry into the United States as a state offense, even for people who now hold green cards or other lawful federal immigration status. It grants state magistrates the authority to issue removal orders, creates a separate offense for refusing to obey those orders, and requires magistrates to continue prosecution even when a defendant has a pending federal immigration case.
That last provision is the one that most directly challenges the traditional federal monopoly on immigration enforcement. Under SB 4, a state judge in Texas does not have to wait for Washington to act, or to defer if Washington chooses not to.
The ACLU of Texas, the national ACLU, and the Texas Civil Rights Project filed a class-action suit against SB 4 on May 4, calling it "among the harshest immigration statutes any state legislature has enacted." Two unnamed Honduran immigrants serve as lead plaintiffs.
U.S. District Court Judge David Alan Ezra responded on May 14 with a 78-page preliminary injunction. Ezra determined the plaintiffs faced likely arrest and possible removal once the reentry provisions took force. But his order was carefully scoped, he blocked only the reentry sections and allowed the rest of SB 4 to begin enforcement on May 15.
That partial block lasted barely two weeks. The Fifth Circuit's Friday order paused Ezra's injunction entirely, reactivating the reentry provisions and the full enforcement architecture of the law while the case continues through the courts.
Judge Leslie Southwick was the lone dissenter on the panel and would have rejected Texas's motion. The court did not disclose the identities of the majority judges or explain its reasoning beyond the procedural stay.
The legal fight over SB 4 has a long history. The Supreme Court previously allowed SB 4 to take effect by maintaining an appeals court stay and sending the case back to the Fifth Circuit for expedited consideration, though the law continued to face constitutional challenges over federal supremacy.
Abbott's full statement on X laid out the stakes as he sees them:
"BREAKING: Texas received a major border security victory. SB 4 makes it a state crime to illegally enter Texas. Shortly after I filed a legal brief defending that law, a federal appeals court ruled to allow it to be enforced while the case continues. We will keep fighting in the courts, working with President Trump, and doing everything necessary to secure our border and protect Texans."
The governor's framing, linking his own legal brief to the court's decision, is notable. Abbott has positioned himself as a hands-on litigant, not just a political cheerleader, in the state's immigration enforcement battles.
That approach mirrors a broader pattern. Across the federal judiciary, immigration appeals boards and courts have increasingly sided with enforcement-oriented positions, overturning lower court rulings that sought to block deportation actions.
The core constitutional argument against SB 4 has always been straightforward: immigration enforcement is a federal responsibility, and states cannot create parallel systems that conflict with or override federal authority. The ACLU's lawsuit rests squarely on that principle.
Judge Ezra himself signaled sympathy for that view in prior proceedings. Fox News reported that Ezra previously stated Texas "cannot regulate the federal field of unlawful entry and removal." Justice Sotomayor, in an earlier Supreme Court dissent, warned that SB 4 "upends the federal-state balance of power that has existed for over a century."
Texas sees it differently. The state's position, reinforced by Abbott's statement, is that when the federal government fails to secure the border, states have both the right and the obligation to act. SB 4 is the most aggressive expression of that theory any state has put into law.
The tension between those two positions is far from resolved. Federal appeals courts remain divided on the boundaries of executive immigration authority, and SB 4's journey through the courts is almost certainly headed for another round at the Supreme Court.
For now, the law is live. Texas police can arrest suspected illegal border crossers under state authority. State magistrates can issue removal orders. Prosecution can proceed regardless of what federal immigration courts are doing with the same defendants.
The ACLU and its co-plaintiffs will continue pressing their challenge. The Fifth Circuit's stay is procedural, not a final ruling on the merits. But every day SB 4 remains in effect, Texas builds a track record of enforcement that strengthens its argument that the law is workable, and that states can fill the gaps Washington leaves open.
Newsmax noted the ruling's significance as part of a broader pattern of appeals court decisions favoring Texas's border enforcement posture. The case now joins a growing docket of immigration disputes winding through the federal judiciary.
The practical consequences extend beyond courtrooms. Census data has already shown border-town population growth collapsing as enforcement pressure mounts from both state and federal authorities. SB 4's full activation adds another layer of deterrence for anyone considering an illegal crossing into Texas.
Several open questions remain. The Fifth Circuit did not explain its reasoning, leaving legal analysts to guess at the constitutional theory supporting the stay. The timeline for a full merits hearing is unclear. And the identities of the majority judges, and their reasoning, remain undisclosed, making it difficult to predict how the panel will ultimately rule.
Meanwhile, other high-profile deportation cases continue to move through the appeals court system, each one shaping the legal landscape that SB 4 will ultimately be judged against.
For years, the argument against state immigration enforcement has been that it's the federal government's job. Texas just demonstrated what happens when a state decides to do the job anyway, and the courts, at least for now, let it.
