Mr. Justice Black
delivered the opinion of the Court.
In response to a subpoena, petitioner appeared as a witness before the United States District Court Grand Jury at Denver, Colorado. There she was asked several questions concerning the Communist Party of Colorado and her employment by it. Petitioner refused to answer these questions on the ground that the answers might tend to incriminate her. She was then taken before the district judge where the questions were again propounded and where she again claimed her constitutional privilege against self-incrimination and refused to testify. The district judge found petitioner guilty of contempt of court and sentenced her to imprisonment for one year. The Court of Appeals for the Tenth Circuit affirmed. 180 F. 2d 103. We granted certiorari because the decision appeared to deny rights guaranteed by the Fifth Amendment. The holding below also was in conflict with recent decisions of the Fifth and Ninth Circuits. Estes v. Potter, 183 F. 2d 865; Alexander v. United States, 181 F. 2d 480.
At the time petitioner was called before the grand jury, the Smith Act was on the statute books making it a crime among other things to advocate knowingly the desirability of overthrow of the Government by force or violence; to organize or help to organize any society or group which teaches, advocates or encourages such overthrow of the Government; to be or become a member of such a group with knowledge of its purposes. These provisions made future prosecution of petitioner far more than “a mere imaginary possibility . . . .” Mason v. United States, 244 U. S. 362, 366; she reasonably could fear that criminal charges might be brought against her if she admitted employment by the Communist Party or intimate knowledge of its workings. Whether such admissions by themselves would support a conviction under a criminal statute is immaterial. Answers to the questions asked by the grand jury would have furnished a link in the chain of evidence needed in a prosecution of petitioner for violation of (or conspiracy to violate) the Smith Act. Prior decisions of this Court have clearly established that under such circumstances, the Constitution gives a witness the privilege of remaining silent. The attempt by the courts below to compel petitioner to testify runs counter to the Fifth Amendment as it has been interpreted from the beginning. United States v. Burr, 25 Fed. Cas., Case No. 14,692e, decided by Chief Justice Marshall in the Circuit Court of the United States for the District of Virginia; Counselman v. Hitchcock, 142 U. S. 547; Ballmann v. Fagin, 200 U. S. 186; Arndstein v. McCarthy, 254 U. S. 71; Boyd v. United States, 116 U. S. 616; cf. United States v. White, 322 U. S. 694, 698, 699.
Reversed.
Me. Justice Clark took no part in the consideration or decision of this case.
The grand jury’s questions which petitioner refused to answer were as follows: “Mrs. Blau, do you know the names of the State officers of the Communist Party of Colorado ?” “Do you know what the organization of the Communist Party of Colorado is, the table of organization of the Communist Party of Colorado?" “Were you ever employed by the Communist Party of Colorado ?” “Mrs. Blau, did you ever have in your possession or custody any of the books and records of the Communist Party of Colorado?” “Did you turn the books and records of the Communist Party of Colorado over to any particular person?” “Do you know the names of any persons who might now have the books and records of the Communist Party of Colorado?” “Could you describe to the grand jury any books and records of the Communist Party of Colorado?”
The Fifth Amendment provides: “No person . . . shall be compelled in any criminal case to be a witness against himself . . . .” U. S. Const., Amend. V.
62 Stat. 808,18 U. S. C. § 2385.
What follows is an opinion from the Supreme Court of the United States. Your task is to determine whether the decision of the court whose decision the Supreme Court reviewed was itself liberal or conservative. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. The lower court's decision direction is unspecifiable if the manner in which the Supreme Court took jurisdiction is original or certification; or if the direction of the Supreme Court's decision is unspecifiable and the main issue pertains to private law or interstate relations
