Texas’ plans to arrest migrants suspected of illegally entering the U.S. will remain on hold under a federal appeals court order that likely prevents enforcement of Republican Gov. Greg Abbott’s new immigration law until a broader decision on whether it is legal.

The 2-1 ruling late Tuesday is the second time a three-judge panel of the 5th U.S. Circuit Court of Appeals has put a temporary hold on the the Texas law. It follows a confusing few hours last week the Supreme Court allowed the law to take effect, setting off anger and anticipation along the U.S.-Mexico border.

The same panel of appeals judges will hear arguments on the law next week.

“I think what we can draw from this, from the chaos that this has been are several conclusions,” said Lisa Graybill, vice president of law and policy at the National Immigration Law Center. “One is that this is clearly a controversial law. Two is that the politics of the justices on the bench are very clearly playing out in their rulings.”

Texas authorities announced no arrests made under the law during that short window on March 19 before the appellate panel stepped in and blocked it.

In Tuesday’s order, Chief Judge Priscilla Richman cited a 2012 Supreme Court decision that struck down portions of a strict Arizona immigration law, including arrest power. The Texas law is considered by opponents to be the most dramatic attempt by a state to police immigration since that Arizona law.

“For nearly 150 years, the Supreme Court has held that the power to control immigration — the entry, admission, and removal of noncitizens — is exclusively a federal power,” wrote Richman, an appointee of Republican President George W. Bush.

The Justice Department has argued that Texas’ law is a clear violation of federal authority and would create chaos at the border. Texas has argued that President Joe Biden’s administration isn’t doing enough to control the border and that the state has a right to take action.

The Texas law, Richman wrote, “creates separate, distinct state criminal offenses and related procedures regarding unauthorized entry of noncitizens into Texas from outside the country and their removal.”

She was joined in the opinion by Judge Irma Carrillo Ramirez, a Biden appointee.

Judge Andrew Oldham, an appointee of former President Donald Trump and a former aide to Abbott, dissented from the majority decision.
