A divided Fifth Circuit lifted the injunction on Texas SB 4 on standing grounds, letting the state arrest undocumented border crossers while leaving preemption unresolved.
A divided Fifth Circuit Court of Appeals vacated the preliminary injunction blocking Texas Senate Bill 4, clearing the way for the state to enforce a law that criminalizes illegal border crossing and authorizes state and local police to arrest undocumented immigrants [1]. The 10-7 en banc court did not reach the underlying constitutional questions, ruling instead that the plaintiff advocacy organizations lacked standing to challenge the law [1]. Texas Attorney General Ken Paxton declared the outcome a victory for state border enforcement authority [1].
SB 4, enacted by the Texas Legislature in 2023, creates a state-law misdemeanor for crossing the border outside a designated port of entry and empowers officers to arrest individuals suspected of violating that provision [1]. The law had been blocked by multiple courts since its passage, surviving a prolonged procedural battle that included prior Fifth Circuit rulings, district court injunctions, and an earlier trip to the Supreme Court [1]. The challengers, including Las Americas Immigrant Advocacy Center, American Gateways, and El Paso County, argued the law conflicted with federal immigration authority and caused direct harm to their clients and operations [1]. The majority concluded those organizations failed to demonstrate the concrete, particularized injury required for Article III standing, leaving the merits of the preemption dispute unresolved [1].
The ruling carries significant doctrinal and practical weight. By disposing of the case on standing grounds, the court avoided addressing whether SB 4 conflicts with the federal government's exclusive authority over immigration enforcement, a question that has divided courts and legal scholars since the law's enactment [1]. The preemption issue remains live, and any future plaintiff with cleaner standing, such as an individual arrested under SB 4, could revive the constitutional challenge in short order [1]. The decision also signals the Fifth Circuit's receptiveness to standing arguments as a threshold tool for deflecting policy-driven litigation, regardless of the underlying substantive controversy [1].
With the injunction vacated, Texas law enforcement agencies may begin making arrests under SB 4 immediately [1]. Advocacy groups are expected to assess whether individuals harmed by enforcement actions can bring new suits with stronger standing profiles [1]. Given the magnitude of the preemption question and the circuit's fractured posture, a petition for certiorari to the Supreme Court remains a likely next step if further lower-court proceedings produce a merits ruling [1].
