To get arbitrary power those seeking that goal must remove accurate accountability from general use. Since Trial by Jury, The Law of the Land, Trial by the Country, a.k.a. The Common Law - real, not counterfeit - was the means by which the end is accurate accountability, then it stands to reason that the usurpers seeking arbitrary power would have to usurp Trial by Jury. If the usurpers merely ordered people to stop using Trial by Jury to maintain accurate accountability, the people would see the usurpation clearly, and the people could then use Trial by Jury to hold the usurpers accountable for that obvious usurpation.

The usurpers have understood for centuries that the way to usurp accurate accountability is to replace the working process with a counterfeit (opposite) process that works as a shield from accurate accountability rather than an open door for accurate accountability.

Lysander Spooner (Essay on the Trial by Jury, 1882):
"The question, then, between trial by jury, as thus described, and trial by the government, is simply a question between liberty and despotism. The authority to judge what are the powers of the government, and what the liberties of the people, must necessarily be vested in one or the other of the parties themselves - the government, or the people; because there is no third party to whom it can be entrusted. If the authority be vested in the government, the government is absolute, and the people have no liberties except such as the government sees fit to indulge them with. If, on the other hand, that authority be vested in the people, then the people have all liberties, (as against the government,) except such as substantially the whole people (through a jury) choose to disclaim; and the government can exercise no power except such as substantially the whole people (through a jury) consent that it may exercise."

"Congress have as much constitutional right to give over all the functions of the United States government into the hands of the state legislatures, to be exercised within each state in such manner as the legislature of such state shall please to exercise them, as they have to thus give up to these legislatures the selection of juries for the courts of the United States.
There has, probably, never been a legal jury, nor a legal trial by jury, in a single court of the United States, since the adoption of the constitution.
These facts show how much reliance can be placed in written constitutions, to control the action of the government, and preserve the liberties of the people.
If the real trial by jury had been preserved in the courts of the United States—that is, if we had had legal juries, and the jurors had known their rights—it is hardly probable that one tenth of the past legislation of Congress would ever have been enacted, or, at least, that, if enacted, it could have been enforced."

Patrick Henry June 5, 1788:
"Here is a revolution as radical as that which separated us from Great Britain. It is radical in this transition; our rights and privileges are endangered, and the sovereignty of the states will be relinquished: And cannot we plainly see that this is actually the case? The rights of conscience, trial by jury, liberty of the press, all your immunities and franchises, all pretensions to human rights and privileges, are rendered insecure, if not lost, by this change, so loudly talked of by some, and inconsiderately by others."

Robert Yates, Brutus I, October 18, 1787:
"The judicial power of the United States is to be vested in a supreme court, and in such inferior courts as Congress may from time to time ordain and establish. The powers of these courts are very extensive; their jurisdiction comprehends all civil causes, except such as arise between citizens of the same state; and it extends to all cases in law and equity arising under the constitution. One inferior court must be established, I presume, in each state at least, with the necessary executive officers appendant thereto. It is easy to see, that in the common course of things, these courts will eclipse the dignity, and take away from the respectability, of the state courts. These courts will be, in themselves, totally independent of the states, deriving their authority from the United States, and receiving from them fixed salaries; and in the course of human events it is to be expected, that they will swallow up all the powers of the courts in the respective states."

George Mason, 1787
"The judiciary of the United States is so constructed and extended, as to absorb and destroy the judiciaries of the several states; thereby rendering laws as tedious, intricate, and expensive, and justice as unattainable by a great part of the community, as in England; and enabling the rich to oppress and ruin the poor."

Thomas Paine, Rights of Man, Page 52
"A government on the principles on which constitutional governments arising out of society are established, cannot have the right of altering itself. If it had, it would be arbitrary. It might make itself what it pleased; and wherever such a right is set up, it shows there is no constitution."

Papers of Dr. James McHenry on the Federal Convention of 1787. (1)
Dr. James McHenry
Philadelphia 14 May 1787:
"Mr. E. Gerry. Does not rise to speak to the merits of the question before the Committee but to the mode.
A distinction has been made between a federal and national government. We ought not to determine that there is this distinction for if we do, it is questionable not only whether this convention can propose an government totally different or whether Congress itself would have a right to pass such a resolution as that before the house. The commission from Massachusets empowers the deputies to proceed agreeably to the recommendation of Congress. This the foundation of the convention. If we have a right to pass this resolution we have a right to annihilate the confederation."

The false "Federalist Party" knew they were usurping the power to change (alter, replace) the existing Federal Constitution; turning a voluntary association for mutual defense into a Profitable Monopoly Arbitrary Nation-State. There is the confession: the smoking gun.
