Texas Immigration Law SB4 Challenged by Justic Department
Justice Department Challenges Texas Immigration Law SB4
The U.S. Department of Justice has filed a lawsuit against Texas and its Republican governor, Greg Abbott, seeking to block the implementation of SB4, a controversial Texas immigration law passed last year. The statute authorizes state police to arrest individuals suspected of crossing the U.S.–Mexico border without authorization. The federal government argues that immigration and border enforcement fall under federal jurisdiction, not the authority of individual states.
If enacted, SB4 would criminalize unauthorized crossings of the Texas–Mexico border. The law would classify such conduct as a misdemeanor punishable by up to six months in jail. According to the Justice Department, the statute violates the U.S. Constitution’s Supremacy Clause and Foreign Commerce Clause, which establish that federal law takes precedence over state legislation.
Federal legal challenge Over Texas Immigration Law
Vanita Gupta, the U.S. associate attorney general, cited constitutional limits on state authority in immigration matters. She stated, “Under the Supremacy Clause of the Constitution and longstanding Supreme Court precedent, states cannot adopt immigration laws that interfere with the framework enacted by Congress. The Justice Department will continue to fulfill its responsibility to uphold the Constitution and enforce federal law.”
Governor Abbott has not issued a formal response to the lawsuit. However, he commented on social media that Texas is “the only government in America trying to stop illegal immigration” and expressed confidence in the law’s legality.
State response and ongoing litigation
In previous actions, Texas officials have referenced the state constitution’s “invasion clause,” describing migrants at the border as a public foreign enemy. Civil rights organizations criticized this language as “extremely dangerous.” It remains unclear whether courts will accept this argument.
The Texas immigration law is scheduled to take effect on March 5. However, ongoing litigation may delay or prevent its enforcement. SB4 forms part of Texas’s broader border security strategy and is associated with Operation Lone Star, a joint effort involving the Texas Department of Public Safety and the Texas Military Department.
