I have a question about "irreparable harm" (1st paragraph).
"irreparable harm to whom"??

Context>>>>>>>>>>>>>>>>>>>>>
Seven states that sued to block the DACA program couldn’t demonstrate that permitting it to continue was causing irreparable harm, a federal judge said on Friday, declining to halt the Obama-era policy that protects young illegal immigrants from deportation.
U.S. District Judge Andrew Hanen, who has previously ruled against DACA-related programs, argued that the states waited too long to seek a preliminary injunction.

"Here, the egg has been scrambled,” Hanen wrote in his ruling. “To try to put it back in the shell with only a preliminary injunction record, and perhaps at great risk to many, does not make sense nor serve the best interests of this country.”

Still, Hanen said that he thinks the program, which stands for Deferred Action for Childhood Arrivals program, is unconstitutional. "If the nation truly wants to have a DACA program, it is up to Congress to say so," Hanen wrote.

"As the Justice Department has consistently argued, DACA is an unlawful attempt to circumvent Congress, and we are pleased the court agreed today," Justice Department spokesman Devin O'Malley said.
