U.S. District Judge Andrew Hanen’s decision late Monday puts on hold Obama’s orders that could spare from deportation as many as five million people who are in the U.S. illegally.

Hanen wrote in a memorandum accompanying his order that the lawsuit should go forward. Without a preliminary injunction, he said, the states would “suffer irreparable harm in this case.”

“The genie would be impossible to put back into the bottle,” he wrote, adding that he agreed that legalizing the presence of millions of people is a “virtually irreversible” action.
