The U.S. Court of Appeals for the Fifth Circuit recently cleared the way for Texas to enforce Senate Bill 4 (SB 4), enabling state officials to arrest individuals suspected of unauthorized entry into the country. This decision follows a contentious legal history, lifting a district court injunction that previously blocked the law’s implementation. The Fifth Circuit’s brief order paused the lower court’s block on key provisions, including the authority of state magistrates to issue removal orders and offenses related to noncompliance.
Judge Leslie Southwick dissented, expressing concerns over the law’s sweeping scope. Notably, SB 4 criminalizes entry into Texas from a foreign nation outside designated ports, imposing misdemeanor charges for first-time offenses and felony penalties for repeat violations. Governor Greg Abbott’s administration views this as a necessary step to maintain state security, aligning with broader federal border security initiatives.
The law, however, faces significant opposition. Critics argue that it unconstitutionally encroaches on federal jurisdiction over immigration. In Arizona v. United States, the Supreme Court invalidated similar state-level immigration enforcement efforts, citing federal preemption. Despite this precedent, Texas has pressed forward, bolstered by Judge James Ho’s assertion that SB 4 falls under Texas’s war powers as per Article I, Section 10 of the U.S. Constitution.
While the Trump administration previously moved to dismiss federal challenges to SB 4, advocacy groups and local governments, including El Paso County, have continued legal proceedings. Following the Fifth Circuit’s en banc decision in April 2026, the American Civil Liberties Union (ACLU) and other civil rights organizations initiated a new class action against the law, leading to a fresh injunction that the Fifth Circuit panel has now stayed.
Governor Abbott responded positively to the ruling, signifying a continued judicial campaign alongside federal support to fortify the state’s immigration policy. Despite the current judicial approval, the litigation surrounding SB 4 remains poised to potentially escalate to the U.S. Supreme Court for a definitive resolution, with wider implications for state versus federal authority on immigration matters.
