"[I]f the policy of the government, upon vital questions, affecting the whole people, is to be irrevocably fixed by decisions of the Supreme Court, the instant they are made, in ordinary litigation between parties, in personal actions, the people will have ceased, to be their own rulers, having, to that extent, practically resigned their government, into the hands of that eminent tribunal.’ May that not be the case in our nation.”

-- Abraham Lincoln
 
 
 
 
"It has long, however, been my opinion, and I have never shrunk from its expression ... that the germ of dissolution of our federal government is in the constitution of the federal Judiciary; an irresponsible body, (for impeachment is scarcely a scare-crow) working like gravity by night and by day, gaining a little today and a little tomorrow, and advancing its noiseless step like a thief, over the field of jurisdiction, until all shall be usurped from the States, and the government of all be consolidated into one."

--Thomas Jefferson, letter to Charles Hammond, 1821
 
 
_"I acknowledge, in the ordinary course of government, that the exposition of the laws and Constitution devolves upon the judicial. But I beg to know upon what principle it can be contended that any one department draws from the Constitution greater powers than another in marking out the limits of the powers of the several departments."

-- James Madison, 1789
