Judge Blocks Key Sections of Texas Immigration Law Hours Before Enforcement
Finn's Take· TL;DR- Judge halted most of Texas SB4's enforcement one day before implementation, citing unconstitutional encroachment on federal immigration authority.
- Law would've made illegal border crossings a state crime with jail time and allowed judges to order deportations to Mexico.
- Civil rights groups won the case; further appeals likely as Texas seeks to enforce stricter state-level immigration controls despite federal jurisdiction concerns.
Last-Minute Legal Victory Halts Controversial Provisions
U.S. District Judge David Alan Ezra granted a preliminary injunction against critical sections of Senate Bill 4 on Thursday, just one day before the controversial Texas immigration law was set to take effect . The ruling represents the latest twist in a complex legal battle that has stretched across multiple court systems and involved everything from Supreme Court interventions to international diplomatic protests.
The judge emphasized the constitutional concerns in his written ruling, stating "it is implausible to imagine each of the fifty United States having their own state immigration policy superseding the powers inherent in the United States as a Nation" . This decision came after the Reagan appointee had signaled during a Wednesday hearing that he considered the law unconstitutional .
The timing proved crucial for civil rights advocates who had rushed to court after the conservative 5th U.S. Circuit Court of Appeals ruled in April that previous plaintiffs lacked standing to challenge the law, effectively clearing the path for implementation in a 10-7 decision .
What the Law Would Have Done
Senate Bill 4, passed in 2023, makes illegal crossings of the Mexico-Texas border a state crime and requires state magistrate judges to order those arrested for illegal entry to leave the country for Mexico if they are convicted, or in lieu of prosecution . Under the law, crossing into Texas illegally from Mexico would be treated as a misdemeanor crime, punishable by up to 180 days in jail and a fine of up to $2,000 .
The legislation would allow state law enforcement officials to stop and detain anyone suspected of entering Texas unlawfully and empower state judges to issue de facto deportation orders . Unlike current state enforcement efforts that require the consent of private property owners for trespassing charges, SB4 would not need such permission.
The law faced immediate international pushback, with the Mexican Ministry of Foreign Affairs condemning SB4 and saying it "categorically rejects any measure that allows state or local authorities to exercise immigration control" .
A Patchwork of Legal Battles
Civil rights groups brought the latest lawsuit earlier this month, arguing that the sections involving the state's judicial system are unconstitutional because they encroach on the federal government's sole authority over immigration laws . The American Civil Liberties Union, the ACLU of Texas and the Texas Civil Rights Project said the judge's decision reaffirmed that immigration laws are not up to the states, while adding that SB 4 would cause widespread racial profiling, stating "Texas cannot override the U.S. Constitution and should stop wasting time attempting to do so" .
The legal journey has been particularly convoluted. SB4 was originally set to go into effect on March 5, 2024, but was blocked by a district court order on February 29, 2024 . The law briefly gained approval when the Supreme Court gave Texas officials permission to jail and prosecute migrants in March 2024, allowing the controversial law to take effect while the 5th Circuit considered its legality .
What Comes Next
While Thursday's ruling blocks key enforcement mechanisms, a provision allowing police to arrest people suspected of illegal entry did activate , creating a partial implementation that could confuse law enforcement and immigrants alike. Attorney General Ken Paxton's office didn't immediately respond to a comment request about potential appeals.
The decision sets up yet another round of appeals in a case that has already traveled from district court to the Supreme Court and back. With immigration remaining a central political issue and Texas continuing to assert state authority over border enforcement, this legal battle appears far from over. The partial nature of Thursday's injunction suggests that even if some provisions remain blocked, the fundamental conflict between state and federal immigration authority will likely require higher court resolution.
