United States Supreme Court Justice Antonin Scalia ruled in the case of United States vs. Williams, 504 U.S. 36 at 48 (1992):
Rooted in long centuries of Anglo-American history, Hannah v. Larche, 363 US 420, 490 (1960) with J. Frankfurter 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 three branches described in the first three Articles. It is a constitutional fixture in its own right.
To be crystal clear: The Grand Jury is a constitutional fixture in its own right. The Grand Jury is not a tool of government to use against its citizens. Justice Scalia determined further, to reinforce that there is no question as to the purpose of the Grand Jury:
In fact, the whole theory of its foundation is that it belongs to no branch of the institutional Government, serving as a kind of buffer or referee between Government and the people. Although the Grand Jury normally operates, of course, in the courthouse and under judicial auspices, its institutional relationship with the judicial branch has traditionally been, so to speak, at arm’s length. Judges’ direct involvement in the Grand Jury has generally been confined to the constitutive one of calling the Grand Jurors together and administering their oath of office.
Besides providing for society to charge individual people for crimes, the Grand Jury is a tool for the citizens to use against a criminal government or our government acting against the designs of our Constitution. And it was specifically designed to prosecute the criminal actions of government employees and their lawyers.
