This has turned into quite the separation-of-powers case.  Trump has unilaterally reset the "effective start date" of the EO after the fact (to deflect Hawaii's claim that the 90 days had run, so the ban was done).  Next he unilaterally issued a list of "bona fide" relationships, and claims it's the authoritative source.  We demur.

So on top of the foundational issues addressed by the 4th and the 9th, we have two brand new, significant, related issues that the Court will need to deal with 𝒅𝒆 𝒏𝒐𝒗𝒐.  And any adverse ruling could set the stage for an executive-judiciary confrontation à la US v. Nixon.

Are the Supremes having buyer's remorse yet?! 

Anyone who hasn't done so already, should read the decision itself and draw your own conclusions.  Well written and fascinating.  It sets the stage very nicely for October.
