The full Fifth Circuit reverses the SB 4 block on a procedural argument, allowing Texas to resume enforcement

The full Fifth Circuit Court of Appeals voted 10-7 to vacate the preliminary injunction blocking Texas SB4, ruling in Las Americas Immigrant Advocacy Center v. McCraw that the original plaintiffs -- El Paso County, Las Americas Immigrant Advocacy Center, and American Gateways -- lacked legal standing under the stricter organizational standing standard the Supreme Court established in FDA v. Alliance for Hippocratic Medicine (2024). The en banc majority explicitly declined to rule on whether SB4 is constitutional, dismissing the case on procedural grounds only. The ruling allowed Texas to begin enforcing SB4 arrest provisions immediately. Attorney General Ken Paxton called the decision a major victory, while the ACLU warned the ruling left the constitutional questions unresolved.
