The Supreme Court on Tuesday gave Texas officials permission to detain and jail migrants suspected of crossing the U.S. southern border without authorization, greenlighting the enforcement of a state immigration law known as SB4 that the Biden administration has called unconstitutional.
Denying a request from the Justice Department, the high court allowed the controversial Texas law, one of Gov. Greg Abbott's signature immigration policies, to take effect while the U.S. Court of Appeals for the 5th Circuit considers the measure's legality.
Passed by the Texas legislature last year, SB4 criminalizes unauthorized migration at the state level, making the act of entering the U.S. outside of a port of entry — already a federal offense — into a state crime. It also creates a felony charge for illegal reentry at the state level.
At the request of the Biden administration, a federal judge last month blocked SB4, finding that the state measure is at odds with federal immigration laws. That ruling was then suspended by the 5th Circuit until Justice Samuel Alito paused the appeals court's order on administrative grounds. Alito extended that pause Monday evening.
On Tuesday, the full court declined to suspend the 5th Circuit's order any longer. The three liberal justices, Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson, dissented.
"The Court gives a green light to a law that will upend the longstanding federal-state balance of power and sow chaos, when the only court to consider the law concluded that it is likely unconstitutional," Sotomayor wrote in a dissenting opinion, joined by Jackson.
What Texas' SB4 immigration law does
SB4 empowers Texas law enforcement officials, at the state and local levels, to stop, jail and prosecute migrants on illegal entry and reentry charges. It also allows Texas judges to order migrants to return to Mexico as an alternative to continuing their prosecution, effectively creating a de facto state deportation system.
The Justice Department has said SB4 conflicts with federal law and the Constitution, noting that immigration enforcement, including arrests and deportations, have long been a federal responsibility. It has also argued the measure harms relations with the Mexican government, which has denounced SB4 as "anti-immigrant" and vowed to reject migrants returned by the state of Texas.
Abbott, who has positioned himself as the leading state critic of President Biden's border policies, has portrayed SB4 as a necessary measure to discourage migrants from crossing the Rio Grande, arguing the federal government has not done enough to deter illegal immigration.
During the last three years, Texas has been at the forefront of challenging federal immigration policies. The state has taken bold actions such as transporting tens of thousands of migrants to Democratic-led cities, setting up razor wire and buoys along border areas to prevent crossings, and initiating numerous legal battles against federal immigration programs.
