US judge blocks key parts of Texas migrant arrest law

May 14 (Reuters) – A federal judge on Thursday blocked Texas authorities from enforcing key parts of a law that would allow state officials to arrest and deport people suspected of ​having illegally crossed the U.S.-Mexico border.

Austin-based U.S. District Judge David Ezra ‌issued a preliminary injunction at the behest of the American Civil Liberties Union and other groups pursuing a class action on behalf of thousands of people who could be subject to the law’s provisions.

Ezra, who was appointed by Republican President Ronald Reagan, said ‌the state ​law was preempted by federal law and improperly ⁠challenged the federal government’s ⁠long-held power to control immigration, naturalization and deportations.

“At the broadest level, SB 4 conflicts with federal immigration law because it provides state officials the power to enforce federal law without federal supervision,” Ezra wrote.

Spokespeople for Republican ​Attorney General Ken Paxton, whose office is defending the law, did not respond to requests for comment.

The lawsuit was filed last week to ⁠prevent parts of the 2023 law from taking ⁠effect, after a federal appeals court in April overturned ​an earlier injunction issued during Democratic President Joe Biden’s administration that had prevented ​the Republican-backed measure known as SB 4 from being enforced.

Republican President ‌Donald Trump’s administration had dropped a case the Biden administration brought challenging the law. Immigrant-rights groups that had also sued pressed on, but the 5th U.S. Circuit Court of Appeals concluded the organizations lacked legal standing to pursue ⁠their case.

The new ACLU-backed lawsuit sought to address that issue by instead suing on behalf of noncitizens who could be subject to four key provisions of ⁠the law, which is ‌set to take effect on Friday.

Those provisions include ones that ⁠make it a state crime for someone to reenter ​the U.S. ‌after deportation, even if they have federal permission ​to do so ⁠or have since obtained a green card, and that give magistrate judges in Texas the power to issue deportation orders.

Lawyers for the plaintiffs in a joint statement hailed Ezra’s ruling.

“Texas cannot override the U.S. Constitution and should stop wasting time attempting to do so,” they said.
