And every single bit of the dicta they cited is COMPLETELY irrelevant to the question they were tasked to decide!
Um.... the question they were asked to decide, was whether or not to grant an emergency stay to the temporary restraining order.
And to assess the grounds for granting a stay, they had to ask whether the court had standing to rule on matters that are alleged to be national security issues -- and they cited relevant precedents to show that they do.
They also acknowledged that the court owes "substantial deference to the immigration and national security policy determinations of the political branches;" however, to grant an emergency stay, the government had to show evidence supporting the request.
Instead, the court said that "the Government has not offered any evidence or even an explanation of how the national security concerns that justified those designations, which triggered visa requirements, can be extrapolated to justify an urgent need for the Executive Order to be immediately reinstated."
Thus, no stay on grounds of national security.
