This isn't the only case challenging the lawfulness of the Obama's immigration actions.   Some two-dozen states have filed suit challenging Obama's recent immigration policy reforms.  Led by Texas, these states claim that the president as exceeded the scope of executive authority in this area.  As I've noted before, I'm skeptical of these arguments on the merits (as is Ilya), and wonder whether the states will be able to satisfy the requirements of Article III standing to bring their claims.  Yet as this case shows, even if the states don't have standing, the legality of the president's actions could nonetheless be decided in federal court.
