Felix Frankfurter

“ Trial courts no doubt must be on guard against confusing offenses to their sensibilities with obstruction to the administration of justice. It is no less important for this Court to use self-restraint in the exercise of its ultimate power to find that a trial court has gone beyond the area in which it can properly punish for contempt. We are not justified in sliding from mere disagreement with the way in which a trial court has dealt with a particular matter, such as petitioner's conduct in the present case, into a condemnation of the court's action as an abuse of discretion. ”

“ On the other hand, when a witness voluntarily testifies, the privilege against self-incrimination is amply respected without need of accepting testimony freed from the antiseptic test of the adversary process. The witness himself, certainly if he is a party, determines the area of disclosure and therefore of inquiry. Such a witness has the choice, after weighing the advantage of the privilege against self-incrimination against the advantage of putting forward his version of the facts and his reliability as a witness, not to testify at all. ”

“ It was taken for granted by petitioner no less than by the Government that for a party insistently to block relevant inquiry on cross-examination subjects him to punishment for contempt in the exercise of the power vested in the federal courts throughout our history. ”
