The Grand Jury as a Sword In a stunning 6 to 3 decision of the U.S. Supreme Court, Justice Antonin Scalia, writing for the majority, confirmed that: The American Grand Jury is neither part of the judicial, executive nor legislative branches of government, but instead belongs to the people. It is in effect a fourth branch of government "governed" and "administered" directly by and on behalf of the American people, and its authority emanates from the "Bill of Rights" and has the power to enforce law and remove people from PUBLIC office.
