Not a snowballs chance in hell.
In a Dictatorship, the law is whatever the Dictator says it is.
Ginsburg is merely playing a game to give the appearance that that the SCOTUS is looking at this objectively.
No way she gives it to the full court.
She is a democrat.
She is not the last word. If 4 justices want it, it goes to the full court unless 5 justices decline to take it. Even if she takes it up, 4 justices must still vote to grant cert.
