U.S. District Judge David A. Ezra blocked key provisions of Texas Senate Bill 4 on Thursday, preventing the immigration law from taking full effect.

The ruling halts a 2023 law that would grant state officials the authority to detain and deport immigrants. This decision prevents the state from implementing these measures as the law was scheduled to become effective on Friday, May 15, 2026 [1, 2].

Judge Ezra issued the injunction in the U.S. District Court in Austin, Texas [2]. The ruling came after two Honduran immigrants sued the state, arguing that the law violates constitutional rights [2]. Civil-rights groups said the legislation was one of the most extreme anti-migrant measures in the country [1, 2].

Reports differ on the exact scope of the injunction. Reuters said four key provisions were blocked [1], while Community Impact said two major provisions were halted [2].

There is also a discrepancy regarding the timing of the order. Some reports say the injunction was issued on May 14, 2026 [1], while other sources say the judge issued the order on May 13, 2026 [2].

Senate Bill 4 represents a significant attempt by Texas to expand state-level immigration enforcement. By allowing state officials to perform tasks typically reserved for the federal government, the law sought to create a state-led system for managing undocumented populations. The federal court's intervention ensures that these specific enforcement mechanisms remain paused while the legal challenge proceeds.

This ruling underscores the ongoing legal tension between state and federal authority over immigration enforcement. By blocking SB 4, the court maintains the status quo where immigration detention and deportation remain primarily federal responsibilities, preventing Texas from unilaterally expanding its police powers over non-citizens.
