Must not be permanently blocked if it is being appealed
A previous ruling was a temporary hold, that was what was being appealed.
This time he made it permanent.
“The judge had previously made the same arguments in a ruling that put a temporary hold on the executive order targeting so-called sanctuary cities. The Trump administration has appealed that decision to the 9th U.S. Circuit Court of Appeals.”
Big question is whether he has the authority for this.
