From the story here:
A federal judge in South Texas on Monday temporarily blocked President Barack Obama's executive action on immigration, giving a coalition of 26 states time to pursue a lawsuit that aims to permanently stop the orders.
U.S. District Judge Andrew Hanen's decision comes after a hearing in Brownsville in January and puts on hold Obama's orders that could spare as many as five million people who are in the U.S. illegally from deportation.
Hanen wrote in a memorandum accompanying his order that the lawsuit should go forward and that without a preliminary injunction the states will "suffer irreparable harm in this case."
"The genie would be impossible to put back into the bottle," he wrote, adding that he agreed with the plaintiffs' argument that legalizing the presence of millions of people is a "virtually irreversible" action. ...
Hanen, who's been on the federal court since 2002 after being nominated by President George W. Bush, regularly handles border cases but wasn't known for being outspoken on immigration until a 2013 case. In an order in that case, Hanen suggested the Homeland Security Department should be arresting parents living in the U.S. illegally who induce their children to cross the border illegally.
