announced the judgment of the Court and an opinion in which The Chief Justice, Mr. Justice Burton and Mr. Justice Clark join.
Petitioner, Agapita Gallegos, was convicted in a District Court of Nebraska of manslaughter and sentenced to ten years’ imprisonment, the maximum penalty. The charge was the slaying of his paramour without deliberation or premeditation. This judgment of conviction was sustained by the Supreme Court of Nebraska over the objection that introduction at the trial of petitioner’s prior statements admitting the homicide violated the Fourteenth Amendment of the Constitution. In view of certain undenied incidents giving color to petitioner’s allegation of unfairness in the prosecution, certiorari was granted to determine whether the due process requirements of the Fourteenth Amendment were violated by the admission of the statements. 341 U. S. 947.
On 'September 19, 1949, at the request of the United. States Immigration and Naturalization Service, petitioner, a thirty-eight-year-old Mexican farm hand who can neither speak nor write English, was arrested, together with his brother, by police officers of El Paso County, at the southwest corner of Texas, and there booked on a charge of vagrancy. Gallegos had been an itinerant farm worker in this country before his arrest and had recently returned here for such work.
'We gather from the abbreviated record that information was sought by'’the Texas authorities as to petitioner’s acts in Nebraska, where he had worked, the preceding year. After arrest, petitioner was questioned regarding his identity. He at once gave a false name. Thereafter, *57he was jailed in a small room for the next twenty-one hours. Further questioning to establish identity was had on September 20, 1949, without result. Folio? ng his second interrogation, petitioner was left alone for forty-eight hours. On September 22, 1949, petitioner was removed from his cell and interrogated. After he gave his name and an admission that he had been in Nebraska, he was reconfined; this time confinement ran for a period of twenty-four hours.
On September 23, 1949, petitioner disclosed details of this Nebraska crime. A statement in respect of the crime was immediately prepared in English. This was read to the petitioner in Spanish, and he thereafter signed it. His Texas detention continued until September 27, 1949. During the entire time no charge was filed against him in any state or federal court nor was he brqught before a magistrate.
We have Gallegos’ evidence as to his Texas confinement, the rooms he was placed in, their condition as to furnishings, and the food provided. His testimony on these points is met only in part by the testimony of the Chief Deputy Sheriff of El Paso, his interrogator.' There were times when Gallegos was not under his direct observation. Nebraska had no other witness for the trial familiar with conditions of the Texas restraint. Gallegos’ testimony through the interpreter concerning these matters is vague. From it one gathers that Gallegos sought to convey the impression that the rooms were cells, that the one he occupied for twenty-one hours was without a bed, that one he occupied was without light or poorly lighted, and that the food was sparse, perhaps not more than a meal a day.
During the questioning in the four-day period from September 19th through the 23d, the state says petitioner was not treated or threatened with violence. His questioning did not last longer than an hour or two on any *58day and according to the record was conducted almost entirely by the state's witness, the Chief Deputy Sheriff. However, Gallegos testifies that he was told that he might be turned over to the Mexican authorities for more severe questioning and that a lie detector might be used upon him. The record shows no flat denial of Gallegos’ assertions contained in the last sentence, but it does show, by testimony of the Deputy Sheriff, that no threats or promises were made and that reference to the Mexican authorities, if made, .was that Gallegos would be turned over to the United States Immigration Service who, in turn, would deliver him to the Mexican Immigration Service. Gallegos also spoke of threatened violence.1
On September 27, 1949, a Nebraska sheriff reached Texas and took petitioner to the Scotts Bluff County, Nebraska, jail, arriving Thursday, September 29, at 1 a. m. Gallegos was questioned on Saturday, October 1, at which time he was interviewed through an interpreter by three county police officers. He described the crime *59for which he was convicted. A transcript in English of the interpreter’s translations of the interview was made and some days later read back to petitioner in a Spanish retranslation. The evidence is that Gallegos confirmed this record. The record shows no claim of mistreatment by Nebraska authorities.
By § 29-406, Neb. Rev. Stat., 1943, a police officer is commanded to take an accused before a magistrate. This was not done until October 13, 1949, when petitioner was brought before the county judge of Scotts Bluff County for a preliminary hearing on. a complaint charging murder in the second degree. This was the first time petitioner was brought before any magistrate or court. As an incident to the hearing, petitioner was asked to plead. He pleaded guilty. These two confessions and the plea weré introduced at petitioner’s trial by the state. On October 15, 1949, before trial, the District Court of Scotts Bluff County found petitioner to be entitled to *60counsel appointed by the court, and counsel was then for the first time appointed.
Petitioner presents in his brief only the following question: ■
“Are confessions and a plea obtained from a prisoner during a period of twenty-five days illegal detention by federal and state officers before being brought before a magistrate and before counsel is appointed to assist the prisoner admissible in evidence?”
An answer requires an examination into the. circumstances of record surrounding the statements.
Before the Supreme Court of Nebraska, on the basis of facts in the record of the trial, it was urged that the confessions and plea were inadmissible because they were the result of. “physical torture and threats of torture, mental duress, illegal transportation and illegal detention,” in violation of the federal and state constitutions. As conviction without acceptance of the voluntary character of the confessions would logically have been impossible, we assume that the jury, under applicable instructions, found the statements voluntary. 152 Neb. 831, 837-840, 43 N. W. 2d 1, 4-6. Evidently, neither judge nor jury accepted the testimony of Gallegos on disputed facts as to coercion. Where direct contradiction of petitioner’s assertions as to conditions of his detention in Texas was unavailable or unobtainable, the jury disregarded or minimized or disbelieved Gallegos to such an extent that his confessions were accepted as voluntary. The Deputy Sheriff, the prosecution witness in the best position to know, denied any coercion by promise, threat or violence. A criminal prosecution approved by the state should not be set aside as violative of due process without clear proof that such drastic action is required to protect federal constitutional rights. While our conclusion on due process *61does not necessarily follow the ultimate determinations of judges or juries as to the voluntary character of a defendant’s statements prior to trial, the better opportunity af7 forded those state agencies to appraise the weight of the evidence, because the witnesses gave it personally before them, leads us to accept their judgment insofar as facts upon which conclusions must be reached are in dispute. The state’s ultimate conclusion on guilt is examined from the due process standpoint in the light of facts undisputed by the state.2 That means not only admitted facts but also those that can be classified from the record as without substantial challenge.
As this Court has been entrusted with power to interpret and apply our Constitution to the protection of the right of an accused to federal due process in state criminal trials, the proper performance of that duty requires us to examine, in cases before us, such undisputed facts as form the basis of a state court’s denial of that right. Kansas City Southern R. Co. v. Albers Comm’n Co., 223 U. S. 573, 591; Norris v. Alabama, 294 U. S. 587, 594; Watts v. Indiana, 338 U. S. 49, 51. A contrary rule would deny to the Federal Government ultimate authority to"" redress a violation of constitutional rights. As state courts also are charged with applying constitutional standards of due process, in recognition of their superior opportunity to appraise conflicting testimony, we give deference to their conclusions on disputed and essential issues of what actually happened. See note 2, infra Its duty compels this Court, however, to decide for itself, on the facts that are undisputed, the constitutional validity of a judgment that denies claimed constitutional rights.
*62Controversies as to facts take various forms. The jury-may reach a verdict of guilty although they resolved some subsidiary fact in favor of the accused. In Gallegos’ case we do not know whether his assertions not directly contradicted as to questionable conditions of his Texas detention and examination were accepted as true by the jury. It is quite possible that the jury thought the confession voluntary even though it believed all of Gallegos’ testimony. As we cannot accept the verdict as a finding solely on disputed facts, we must weigh Gallegos’ uncontradicted testimony along with the undisputed facts. We are not free, as Nebraska was, tb leave to the jury determinations of facts upon which the admissibility of the statements is based.3
The issue of federal due process now tendered is to be considered only on uncontroverted facts. . The answer to the question presented depends upon whether there is a violation of the Due Process Clause of the Fourteenth Amendment from the admitted circumstances that *63the two confessions of September 23 and October 1 were given to police officers after arrest in Texas on September 19,1949, while no magistrate with supervisory power over the examinations was present and while the accused was without counsel. Circumstances surrounding the Texas, as well as the Nebraska, confession must be appraised because Nebraska introduced the Texas confession in evidence in the trial. The use of any confession obtained in violation of due process requires the reversal of a conviction even though unchallenged evidence, adequate to convict, remains. Malinski v. New York, 324 U. S. 401, 404. Both states require fugitives from justice to be promptly taken before a magistrate on arrest for extradition. Texas, Vernon’s Code of Criminal Procedure, Arts. 998, 999, 217. Neb. Rev. Stat., 1943, §§ 29-713, 29-715. The question must be weighed in the light of the uncontradicted portion of Gallegos’ own testimony of harsh treatment and the answers of the prosecution and the judge and the jury. The plea of guilty at the preliminary hearing on October 13 is also a factor. We therefore limit our examination to an inquiry as to whether use at trial of these admissions of guilt theretofore made by an accused violates the Fourteenth Amendment.
The decision and judgment below determine for us that under the law of Nebraska such detention and examination, without appearance or arraignment, do not require exclusion of the confessions or plea as involuntary.4 The rule of the McNabb case,, considered recently in United States v. Carignan, 342 U. S. 36, is not a limitation im*64posed by the Due Process Clause. McNabb v. United States, 318 U. S. 332, 340; Lyons v. Oklahoma, 322 U. S. 596, 597, note 2. Compliance with the McNabb rule is required in federal courts by this Court through its power of supervision over the procedure and practices of federal courts in the trial of criminal cases. That power over state criminal trials is not vested in this Court. A confession can be declared inadmissible in a state criminal trial by this Court only when the circumstances under which it is received violate those “fundamental principles of liberty and justice” protected by the Fourteenth Amendment against infraction by any state.5
The Federal Constitution does not command a state to furnish defendants counsel as a matter of course, as is required by the Sixth Amendment in federal prosecutions.6 Lack of counsel at state noncapital trials denies federal constitutional protection only when the absence results in a denial to accused of the essentials of justice.7 *65Lack of counsel prior to trial certainly has no greater effect. Lyons v. Oklahoma, supra, p. 599. “The mere fact that a confession was made while in the custody of the police does not render it-inadmissible.” McNabb v. United States, 318 U. S. 332, 346; cf. United States v. Carignan, 342 U. S. 36, 39.
Prolonged detention without a charge of crime or without preliminary appearance before a magistrate, the lack of counsel before, during, or after arraignment,- and confession to the police in private, are, however, elements that should be considered in determining whether a confession, permitted to be introduced and relied upon at a trial, has been obtained under such circumstances that its use violates due process. Watts v. Indiana, 338 U. S. 49, 54. Of course, the plea of guilty at the preliminary hearing should be treated in the same way as the confessions.
So far as due process affects admissions before trial of the defendant, the accepted test is their voluntariness.8 This requires appraisal, of the facts of each particular case open to consideration by this Court. In recent cases, where undisputed facts existed far more likely to produce involuntary confessions than those in this case, there was disagreement as to whether due process was violated.9 *66The facts here to support a claim of denial of due process are not so convincing.
Certiorari was granted in this case because the record disclosed a serious charge under the Due Process Clause against Nebraska procedure in a criminal case. We have carefully weighed the circumstances of the petitioner’s *67lack of education and familiarity with our law, his experience and condition in life, his need for advice of counsel as to the law of homicide and the probable effect on such a man of interrogation during confinement. We have also taken into consideration Gallegos’ uncontradicted testimony about his accommodations, his limited amounts of *68food and certain threats made by a Texas assistant sheriff not present at the trial. The uncertain character of this uncontradicted testimony, its lack of definiteness; and the action of the trial judge and jury lead us to place little weight upon it. Our position is confirmed by Gallegos’ reiteration of his confession while in custody in Nebraska, when he charges no coercion except detention. See Lyons v. Oklahoma, 322 U. S. 596, 603.
We cannot say that Nebraska has here violated standards of decency or justice in this conviction.

152 Neb. 839, 43 N. W. 2d 5:
“While there is testimony given by the defendant from which the jury could have found that the confessions made were involuntary due to the manner in which defendant was held in confinement, the treatment received while so held, and the threats made; however, the testimony of the authorities in charge, both at El Paso and Scottsbluff, deny these facts and when their testimony is taken together with certain testimony of the defendant, it presents a factual situation from which the jury could properly find that the confessions were freely and voluntarily made. This includes the issue presented by the evidence offered as to whether or not the complaint was properly translated at the preliminary hearing so it was understood by the defendant in making his plea thereto. It also includes the question of whether or not he understood the nature or degree of the crime with which he was charged. These issues both relate themselves directly to the question of whether or not he understood what he was doing when he made his admission of guilt and consequently relate directly to whether it was voluntarily or involuntarily made.”
Gallegos v. State, 152 Neb. 831, 839-840, 43 N. W. 2d 1, 6:
“In regard to how soon after a person is arrested he must be given a preliminary hearing we said in Maher v. State, 144 Neb. 463, 13 N. W. 2d 641: ‘The question as to the time in which the defendant should be given a preliminary hearing is a question for the court. There can be no precise length of time, after the arrest of a person, in which he must be given a hearing. The theory of the law is that *64he must be given a hearing as soon as possible. A person charged should be given -a preliminary hearing just as soon as the nature and circumstances of the case will permit.’
“. . . Here the court, in the first instance, heard all of the evidence relating thereto and determined that sufficient foundation had been laid for their admission. The evidence was then presented to the jury and the question as to their character, whether voluntary or involuntary, was submitted to it by the court’s instructions Nos. 12, 13, and 14. We find the facts and circumstances relating to the giving of the two confessions and the admission of guilt at the preliminary hearing justified the trial court in admitting them in evidence in the first instance and submitting their character, whether voluntary or involuntary, to the jury. See Kitts v. State [151 Neb. 679, 39 N. W. 2d 283].”

Watts v. Indiana, 338 U. S. 49, 51, 52:
“On November 12, 1947, a Wednesday, petitioner was arrested and held as the suspected perpetrator of an alleged criminal assault earlier in the day. Later the same- day, in the vicinity of this occurrence, a woman was found dead under conditions • suggesting murder in the course of an attempted criminal assault. Suspicion of murder quickly turned towards petitioner and the police began to question him. They took him from the county jail to State Police Headquarters, where he was questioned by officers in relays from about 11:30 that night until sometime between 2:30 and 3 o’clock the following morning. The same procedure of persistent *66interrogation from about 5:30 in the afternoon until about 3 o’clock the following morning, by a relay of six to eight officers, was pursued on-Thursday the 13th, Friday the 14th, Saturday the 15th, Monday the 17th. Sunday was a day of rest from interrogation. About 3 o’clock on Tuesday morning, November 18, the petitioner made an incriminating statement after continuous questioning since 6 o’clock of .the preceding evening. The statement did not satisfy the prosecutor who had been called in and he then took petitioner in hand. Petitioner, questioned by an interrogator of twenty years’ experience as lawyer, judge and prosecutor, yielded a more incriminating document.
“Until his inculpatory statements were secured, the petitioner was a prisoner in the exclusive control of the prosecuting authorities. He was kept for the first two days in solitary confinement in a cell aptly enough called ‘the hole’ in view of its «physical conditions as described by the State’s witnesses. Apart from the five night sessions, the police intermittently interrogated Watts during the day and on three days drove him around town, hours at a time, with a view to eliciting identifications and other disclosures. Although the law of Indiana required that petitioner be given a prompt preliminary hearing before a magistrate, with all the protection a hearing was intended to give him, the petitioner was not only given no hearing during the entire period of interrogation but was without friendly or professional aid and without advice as to his constitutional rights. Disregard of rudimentary needs of life — opportunities for sleep and a decent allowance of food — are also relevant, not as aggravating elements of petitioner’s treatment, but as part of. the total situation out of which his confessions came and which stamped their character.”
Turner v. Pennsylvania, 338 U. S. 62, 63-64:
“The officers making the arrest had no warrant and did not tell the petitioner why he was being arrested. These officers began to question the petitioner as soon as they reached the City Hall police station: One of them examined the petitioner for three hours on that afternoon and again that night from eight to eleven o’clock. From *67time to time other officers joined in the interrogation. Petitioner persistently denied any knowledge of the murder.
“The next morning, June 4, the petitioner was booked on the police records as being held for questioning. Later that day he was questioned for about four hours more. On June 5 he was inter- ' rogated for another four hours and on the 6th for day and night sessions totaling six hours. The questioning was conducted sometimes by one officer and at other times by several working together; it appears, in fact, that whenever one of the police officers interested in the investigation had any free time he would have the pétitioner brought from his cell for questioning.
“On June 7, the day when a confession was finally obtained, questioning began in the afternoon and continued for three hours. Later, that day the officers who had been present during the afternoon returned with others to resume the examination of petitioner. Despite the fact that he was falsely told that other suspects had ‘opened up’on him, petitioner repeatedly denied guilt. But finally, at about eleven o’clock, petitioner stated that he had killed the person for whose murder he was later arraigned.”.
Harris v. South Carolina, 338 U. S. 68, 69-70:
“On Monday night questioning began in earnest. At least five officers worked in relays, relieving each other from time to time to permit respite from the stifling heat of the cubicle in which the interrogation was conducted. Throughout the evening petitioner denied that he had killed the Bennetts. On Tuesday the questioning continued under the same conditions from 1:30 in the afternoon until past one the following morning with only an hour’s interval at 5:30. On Wednesday afternoon the Chief of the State Constabulary, with half a dozen of his men, questioned petitioner for about an hour, and the local authorities carried ón the interrogation for three and a half hours longer. At 6:30 that evening the examination resumed. Petitioner continued to deny implication in the killings. The sheriff then threatened to arrest petitioner’s, mother for handling stolen property. Petitioner replied, ‘Don’t get my mother--mixed un in *68it and I will tell you the truth.’ Petitioner, then stated in substance what appears in the confession introduced at the trial. ' The session ended at midnight.
“Petitioner was not informed of his rights under South Carolina law, such as the right to secure a lawyer, the right to request a preliminary hearing, or the right to remain silent. No preliminary hearing was ever given and his confession does not even contain the usual statement that he was told that what he said might be used against him. During the whole period of interrogation he was denied the benefit of consultation with family and friends and was ' surrounded by as many as a dozen members of a dominant group in positions of authority. It is relevant to note that Harris was an illiterate.”-
