The judiciary, from the nature of its functions, will always be
the least dangerous to the political rights of the Constitution; because it
will be least in a capacity to annoy or injure them.
It would be a very dangerous doctrine to consider the
judges as the ultimate arbiters of all constitutional questions. It is one
which would place us under the despotism of an oligarchy.... The
Constitution has erected no such single tribunal, knowing that to whatever
hands confided, with the corruptions of time and party, its members would
become despots. It has more wisely made all the departments co-equal and
co-sovereign within themselves.
– Thomas Jefferson
... Is there, then, not remedy for usurpations in which the Supreme Court of
the U. S. concur? Yes: ... remonstrances and instructions; recurring
elections and impeachments.
– James Madison
