The Supreme Court today issued an order that temporarily allows a new Texas law to go into effect, giving state officials the authority to arrest and deport migrants who enter Texas without authorization.

The Biden administration had sued to block the law, arguing that it interfered with the federal government’s power to set immigration policy and to conduct foreign affairs. Texas rejected that position, saying it “has the sovereign right to defend itself.”

It was unclear when Texas would begin putting the law into effect. Here’s the latest from my colleagues on the ground in Texas.

Today’s order, like nearly all Supreme Court decisions on emergency applications, gave no reasoning. But Justices Amy Coney Barrett and Brett Kavanaugh filed an opinion saying that they were returning the case to an appeals court, which would decide if the law should be paused while the appeal process moves forward.

The court’s three liberal members dissented. They argued that the Texas law upended the federal government’s authority and chastised the court’s conservative majority for opening the door for “further chaos and crisis in immigration enforcement.”
