Antonin Scalia effectively codified the unique independent power of the Fourth Branch into the hands of all citizens sitting as federal grand jurors. In discussing that power and unique independence granted to the grand jury, the United States Supreme Court, in United States v. Williams, 504 U.S. 36 at 48 (1992), Justice Scalia, delivering the opinion of the court, laid down the law of the land:
[R]ooted in long centuries of Anglo-American history, Hannah v. Larche, 363 U.S. 420, 490 (1960) (Frankfurter, J., concurring in result), the grand jury is mentioned in the Bill of Rights, but not in the body of the Constitution. It has not been textually assigned, therefore, to any of the branches described in the first three Articles. It `is a constitutional fixture in its own right. United States v. Chanen, 549 F.2d 1306, 1312 (CA9 1977) (quoting Nixon v. Sirica, 159 U.S. App. D.C. 58, 70, n. 54, 487 F.2d 700, 712, n. 54 (1973)), cert. denied, 434 U.S. 825 (1977).
Of course these clowns were not Federal grand jurors, but make believe grand jurors. Whose authority is similarly make believe.
