What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
IN RE MURCHISON et al.
No. 405.
Argued April 20, 1955.
Decided May 16, 1955.
William, L. Colden argued the cause for petitioners. With him on the brief were James A. Cobb, George E. C. Hayes and Charles W. Jones.
Edmund E. Shepherd, Solicitor General, argued the cause for the State of Michigan, respondent. With him on the brief were Thomas M. Kavanagh, Attorney General, and Daniel J. O’Hara, Assistant Attorney General.
Mr. Justice Black
delivered the opinion of the Court.
Michigan law authorizes any judge of its courts of record to act as a so-called “one-man grand jury.” He can compel witnesses to appear before him in secret to testify about suspected crimes. We have previously held that such a Michigan “judge-grand jury” cannot consistently with the Due Process Clause of the Fourteenth Amendment summarily convict a witness of contempt for conduct in the secret hearings. In re Oliver, 333 U. S. 257. We held that before such a conviction could stand, due process requires as a minimum that an accused be given a public trial after reasonable notice of the charges, have a right to examine witnesses against him, call witnesses on his own behalf, and be represented by counsel. The question now before us is whether a contempt proceeding conducted in accordance with these standards complies with the due process requirement of an impartial tribunal where the same judge presiding at the contempt hearing had also served as the “one-man grand jury” out of which the contempt charges arose. This does not involve, of course, the long-exercised power of courts summarily to punish certain conduct occurring in open court.
The petitioners, Murchison and White, were called as witnesses before a “one-man judge-grand jury.” Murchison, a Detroit policeman, was interrogated at length in the judge’s secret hearings where questions were asked him about suspected gambling in Detroit and bribery of policemen. His answers left the judge persuaded that he had committed perjury, particularly in view of other evidence before the “judge-grand jury.” The judge then charged Murchison with perjury and ordered him to appear and show cause why he should not be punished for criminal contempt. White, the other petitioner, was also summoned to appear as a witness in the same “one-man grand jury” hearing. Asked numerous questions about gambling and bribery, he refused to answer on the ground that he was entitled under Michigan law to have counsel present with him. The “judge-grand jury” charged White with contempt and ordered him to appear and show cause. The judge who had been the “grand jury” then tried both petitioners in open court, convicted and sentenced them for contempt. Petitioners objected to being tried for contempt by this particular judge for a number of reasons including: (1) Michigan law expressly provides that a judge conducting a “one-man grand jury” inquiry will be disqualified from hearing or trying any case arising from his inquiry or from hearing any motion to dismiss or quash any complaint or indictment growing out of it, or from hearing any charge of contempt “except alleged contempt for neglect or refusal to appear in response to a summons or subpoena”; (2) trial before the judge who was at the same time the complainant, indicter and prosecutor, constituted a denial of the fair and impartial trial required by the Due Process Clause of the Fourteenth Amendment to the Constitution of the United States. The trial judge answered the first challenge by holding that the state statute barring him from trying the contempt cases violated the Michigan Constitution on the ground that it would deprive a judge of inherent power to punish contempt. This interpretation of the Michigan Constitution is binding here. As to the second challenge the trial judge held that due process did not forbid him to try the contempt charges. He also rejected other constitutional contentions made by petitioners. The State Supreme Court sustained all the trial judge’s holdings and affirmed. Importance of the federal constitutional questions raised caused us to grant certiorari. The view we take makes it unnecessary for us to consider or decide any of those questions except the due process challenge to trial by the judge who had conducted the secret “one-man grand jury” proceedings.
A fair trial in a fair tribunal is a basic requirement of due process. Fairness of course requires an absence of actual bias in the trial of cases. But our system of law has always endeavored to prevent even the probability of unfairness. To this end no man can be a judge in his own case and no man is permitted to try cases where he has an interest in the outcome. That interest cannot be defined with precision. Circumstances and relationships must be considered. This Court has said, however, that “every procedure which would offer a possible temptation to the average man as a judge . . . not to hold the balance nice, clear and true between the State and the accused, denies the latter due process of law.” Tumey v. Ohio, 273 U. S. 510, 532. Such a stringent rule may sometimes bar tria] by judges who have no actual bias and who would do their very best to weigh the scales of justice equally between contending parties. But to perform its high function in the best way “justice must satisfy the appearance of justice.” Offutt v. United States, 348 U.S. 11, 14.
It would be very strange if our system of law permitted a judge to act as a grand jury and then try the very persons accused as a result of his investigations. Perhaps no State has ever forced a defendant to accept grand jurors as proper trial jurors to pass on charges growing out of their hearings. A single “judge-grand jury” is even more a part of the accusatory process than an ordinary lay grand juror. Having been a part of that process a judge cannot be, in the very nature of things, wholly disinterested in the conviction or acquittal of those accused. While he would not likely have all the zeal of a prosecutor, it can certainly not be said that he would have none of that zeal. Fair trials are too important a part of our free society to let prosecuting judges be trial judges of the charges they prefer. It is true that contempt committed in a trial courtroom can under some circumstances be punished summarily by the trial judge. See Cooke v. United States, 267 U. S. 517, 539. But adjudication by a trial judge of a contempt committed in his immediate presence in open court cannot be likened to the proceedings here. For we held in the Oliver case that a person charged with contempt before a “one-man grand jury” could not be summarily tried.
As a practical matter it is difficult if not impossible for a judge to free himself from the influence of what took place in his “grand-jury” secret session. His recollection of that is likely to weigh far more heavily with him than any testimony given in the open hearings. That it sometimes does is illustrated by an incident which occurred in White’s case. In finding White guilty of contempt the trial judge said, “there is one thing the record does not show, and that was Mr. White’s attitude, and I must say that his attitude was almost insolent in the manner in which he answered questions and his attitude upon the witness stand. . . . Not only was the personal attitude insolent, but it was defiant, and I want to put that on the record.” In answer to defense counsel’s motion to strike these statements because they were not part of the original record the judge said, “That is something . . . that wouldn’t appear on the record, but it would be very evident to the court.” Thus the judge whom due process requires to be impartial in weighing the evidence presented before him, called on his own personal knowledge and impression of what had occurred in the grand jury room and his judgment was based in part on this impression, the accuracy of which could not be tested by adequate cross-examination.
This incident also shows that the judge was doubtless more familiar with the facts and circumstances in which the charges were rooted than was any other witness. There were no public witnesses upon whom petitioners could call to give disinterested testimony concerning what took place in the secret chambers of the judge. If there had been they might have been able to refute the judge’s statement about White’s insolence. Moreover, as shown by the judge’s statement here, a “judge-grand jury” might himself many times be a very material witness in a later trial for contempt. If the charge should be heard before that judge, the result would be either that the defendant must be deprived of examining or cross-examining him or else there would be the spectacle of the trial judge presenting testimony upon which he must finally pass in determining the guilt or innocence of the defendant. In either event the State would have the benefit of the judge’s personal knowledge while the accused would be denied an effective opportunity to cross-examine. The right of a defendant to examine and cross-examine witnesses is too essential to a fair trial to have that right jeopardized in such way.
We hold that it was a violation of due process for the “judge-grand jury” to try these petitioners, and it was therefore error for the Supreme Court of Michigan to uphold the convictions. The judgments are reversed and the causes are remanded for proceedings not inconsistent with this opinion. „ , *

The contempt charge signed by the judge reads in part as follows:
“It therefore appearing . . . that the said Patrolman Lee Roy Murchinson [sic] has been guilty of wilfull and corrupt perjury, which perjury has an obstructive effect upon the judicial inquiry being conducted by this court and the said Patrolman Lee Roy Murchinson [sic] obstructed the judicial function of the court by wilfully giving false answers as aforesaid, and did also tend to impair the respect for the authority of the court, all of which perjury and false answers given by the said witness aforesaid was committed during the sitting of, in the presence and view of this court and constitutes criminal contempt;
“It is therefore ordered that the said Patrolman Lee Roy Murchin-son [sic] appear before this court on the tenth day of May, 1954, at 10:00 o’clock in the forenoon and show cause why he should not be punished for criminal contempt of this court because of his aforesaid acts.”

That we lay aside certain other federal constitutional challenges by petitioners is not to be taken as any intimation that we have passed on them one way or another.
See, e. g., Note, 50 L. R. A. (N. S.) 933, 953-954, 970-971.
Apparently the trial judge here did consider himself a part of the prosecution. In passing on a request by Murchison’s counsel for a two-day postponement of the contempt trial the judge said, “There are two points that suggest themselves to me.
“One is that if the respondent is going to claim that he was in Shrewsberry, Ontario, Canada, on March 9, 1954, that we ought to be furnished with information so that we could between now and two days from now, which I am going to give you, we could do some checking and investigating ourselves.” (Emphasis supplied.)
Because of the judge’s dual position the view he took of his function is not at all surprising.
See, e. g., Queen v. London County Council, [1892] 1 Q. B. 190; Wisconsin ex rel. Getchel v. Bradish, 95 Wis. 205, 70 N. W. 172.
