I should say the defendants have done just that for which they are indicted. If I might agree to their conviction without creating a precedent, I che… - Robert H. Jackson

Lying has always been a highly approved Nazi technique. Hitler, in Mein Kampf, advocated mendacity as a policy. … Nor is the lie direct the only means of falsehood. They all speak with a Nazi double meaning with which to deceive the unwary. In the Nazi dictionary of sardonic euphemisms "Final solution" of the Jewish problem was a phrase which meant extermination; "Special treatment" of prisoners of war meant killing; "Protective custody" meant concentration camp; "Duty labour" meant slave labour; and an order to "take a firm attitude" or "take positive measures" meant to act with unrestrained savagery. … Before we accept their word at what seems to be its face value, we must always look for hidden meanings. … Besides outright false statements and those with double meanings, there are also other circumventions of truth in the nature of fantastic explanations and absurd professions. … The record is full of other examples of dissimulations and evasions. Even Schacht showed that he, too, had adopted the Nazi attitude that truth is any story which succeeds. Confronted on cross-examination with a long record of broken vows and false words, he declared in justification — and I quote from the record: "I think you can score many more successes when you want to lead someone if you don't tell them the truth than if you tell them the truth." This was the philosophy of the National Socialists. When for years they have deceived the world, and masked falsehood with plausibilities, can anyone be surprised that they continue that habit of a lifetime in this dock? Credibility is one of the main issues of this trial. Only those who have failed to learn the bitter lessons of the last decade can doubt that men who have always played on the unsuspecting credulity of generous opponents would not hesitate to do the same now. It is against such a background that these defendants now ask this Tribunal to say that they are not guilty of planning, executing, or conspiring to commit this long list of crimes and wrongs. They stand before the record of this Trial as bloodstained Gloucester stood by the body of his slain king. He begged of the widow, as they beg of you: "Say I slew them not." And the Queen replied, "Then say they were not slain. But dead they are..." If you were to say of these men that they are not guilty, it would be as true to say that there has been no war, there are no slain, there has been no crime.

The case is made difficult not because the principles of its decision are obscure but because the flag involved is our own. Nevertheless, we apply the limitations of the Constitution with no fear that freedom to be intellectually and spiritually diverse or even contrary will disintegrate the social organization. To believe that patriotism will not flourish if patriotic ceremonies are voluntary and spontaneous instead of a compulsory routine is to make an unflattering estimate of the appeal of our institutions to free minds. We can have intellectual individualism and the rich cultural diversities that we owe to exceptional minds only at the price of occasional eccentricity and abnormal attitudes. When they are so harmless to others or to the State as those we deal with here, the price is not too great. But freedom to differ is not limited to things that do not matter much. That would be a mere shadow of freedom. The test of its substance is the right to differ as to things that touch the heart of the existing order.

Procedural fairness, if not all that originally was meant by due process of law, is at least what it most uncompromisingly requires. Procedural due process is more elemental and less flexible than substantive due process. It yields less to the times, varies less with conditions, and defers much less to legislative judgment. Insofar as it is technical law, it must be a specialized responsibility within the competence of the judiciary on which they do not bend before political branches of the Government, as they should on matters of policy which compromise substantive law. If it be conceded that in some way [that the agency could take the action it did], does it matter what the procedure is? Only the untaught layman or the charlatan lawyer can answer that procedure matters not. Procedural fairness and regularity are of the indispensable essence of liberty. Severe substantive laws can be endured if they are fairly and impartially applied. Indeed, if put to the choice, one might well prefer to live under Soviet substantive law applied in good faith by our common-law procedures than under our substantive law enforced by Soviet procedural practices. Let it not be overlooked that due process of law is not for the sole benefit of an accused. It is the best insurance for the Government itself against those blunders which leave lasting stains on a system of justice but which are bound to occur on ex parte consideration.
