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. 
                                                  – Alexander Hamilton

     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
