Texas Immigration Law SB 4 Faces New Legal Challenges

A federal appeals court has cleared the way for Texas to enforce Senate Bill 4, a 2023 law that establishes state-level criminal penalties for unauthorized entry into the country [1]. In response to the ruling, a coalition of civil rights organizations filed a new lawsuit on Monday seeking to halt the law before it takes effect on May 15 [1].

Key takeaways

• Senate Bill 4 creates a state-level crime for entering the U.S. without authorization and allows state magistrates to order deportations [1].
• The Fifth Circuit Court of Appeals recently lifted a long-standing injunction that had previously blocked the law’s enforcement [2].
• Civil rights groups, including the ACLU of Texas and the Texas Civil Rights Project, argue the law is unconstitutional because immigration enforcement is an exclusive federal power [1].
• The new lawsuit challenges four specific provisions, including the criminalization of re-entry and the authority of state magistrates to oversee deportation proceedings [1].

Legal battle over state authority

The legal conflict centers on whether Texas has the authority to intervene in immigration enforcement, a domain historically reserved for the federal government [1]. Senate Bill 4 allows state and local law enforcement to arrest individuals suspected of crossing the border illegally and empowers state magistrates to issue removal orders [2]. The law further mandates that these prosecutions continue even if an individual has a pending federal immigration claim, such as an asylum request [1].

The recent decision by the Fifth Circuit Court of Appeals to lift the injunction was not unanimous, with Judge Leslie Southwick dissenting from the panel’s ruling [2]. While the court’s order provided few details, it effectively reversed a lower court’s previous block on the legislation [2]. Texas Governor Greg Abbott celebrated the decision on social media, stating that the state would continue to work toward securing the border [2].

Challenges to constitutionality

The plaintiffs in the new lawsuit, which include the Texas Civil Rights Project and the ACLU, contend that the law violates the U.S. Constitution by attempting to preempt federal authority [1]. They argue that the provisions are unconstitutional and could lead to the separation of families and increased racial profiling across the state [1].

The litigation follows a complex procedural history. While the Biden administration initially challenged the law in 2024, the Trump administration later terminated the Department of Justice’s participation in the case [1]. The current lawsuit aims to stop the law from being implemented on May 15, marking the latest effort in a years-long struggle to determine the boundaries of state power regarding immigration [1].

Why it matters

The implementation of Senate Bill 4 represents a significant shift in the relationship between state and federal immigration enforcement. By creating a state-level crime for unauthorized entry, Texas is challenging long-standing legal precedents that designate immigration as the sole responsibility of the federal government [1]. As the May 15 deadline approaches, the outcome of the new lawsuit will determine whether state authorities can legally exercise powers traditionally held by federal agencies, potentially setting a precedent for other states considering similar legislation [1].
