Although I refuse to click anything CNN to read the court’s decision, I assume from the quote in the excerpt that the judges did the exact opposite of “legislating from the bench.” Indeed, while the federal rules of civil procedure provide for the appointment os a special master, there is no such provision in the federal rules of criminal procedure.
The text of the ruling:
