Judge is the same one that was in charge of the FISA courts. Seems the woman does not want to or is incapable of making good legal decisions.
She's on sound legal footing with the latest ruling - it's the USCIS who's been slacking off, trying to skate by with memos rather than formally submitted and commented regulation changes. Much like the half-a**ed decision to say 'we can't continue the DACA policy because it's unconstitutional' rather than 'we are making the policy decision to rescind DACA', which left the door wide open for successful court challenges.
