delivered the opinion of the Court.
Petitioners Gordon and MacLeod were convicted on an indictment of four counts, two charging unlawful possession of goods stolen while in interstate commerce 1 and two that defendants caused this property to be further transported in interstate commerce. 2 The Court of Appeals affirmed, 3 and we granted certiorari limited to questions concerning production and admission of documentary evidence tending to impeach the testimony of a prosecution witness. 4
The Government proved that film being shipped from Rochester, New York, to Chicago, Illinois, was stolen from a truck in Chicago and that part of it later had been recovered in Detroit. To implicate the two petitioners, it relied principally on one Marshall, who, in Detroit, had pleaded guilty to unlawful possession of the film. Marshall testified that he and a codefendant, Swartz, who died before trial, on several occasions had driven from Detroit to Chicago and back. On each visit they had stopped at petitioner Gordon’s Chicago jewelry store. On one trip, according to Marshall, Gordon accompanied them to a garage in that city and there Gordon and a man resembling MacLeod helped to load into Marshall’s car film that was stacked in the garage. A week later, Marshall said, he and Swartz again called on Gordon, when the latter sent them to see “Ken” at an address which he wrote on a piece of paper. At this address, MacLeod identified himself as “Ken,” and again the three men loaded film from the garage into Marshall’s car.
Both petitioners took the stand and denied complicity in the theft and knowledge that the film was stolen. While their physical movements as recited by them were not materially different from those related by government witnesses, petitioners gave a different and innocent version of the relationship of their acts to the criminal transactions. Gordon testified that the deceased Swartz was a business acquaintance who asked on' the first visit if Gordon knew of a garage where a truck could be temporarily stored. Gordon called MacLeod, who was his partner in a rooming-house venture, and told him that he would send two men over who wished to use a garage back of the rooming house. MacLeod testified that he had not known either of the men before they placed a truck in the garage and that, at their request, he had helped load film from the truck into Marshall’s car merely as a favor.
On cross-examination, Marshall admitted that between his apprehension and his final statement to the Government, which implicated petitioners, he had made three or four statements which did not. Petitioners requested the trial judge to order the Government to produce these earlier statements. The request was denied. Marshall also admitted that, one week before he made any statement incriminating petitioners, he had pleaded guilty to unlawful possession of the film in a federal court in Detroit. He was still unsentenced and no date for sentencing had been set, although nine months had elapsed since this plea was received. He denied that he had received
The trial judge in his charge and the Court of Appeals in its opinion 5 recognized that, where, as here, the Government’s case may stand or fall on the jury’s belief or disbelief of one witness, his credibility is subject to close scrutiny. But the question for this Court is whether rejection of petitioners’ two efforts to impeach the credibility of Marshall did not withhold from the jury information necessary to a discriminating appraisal of his trustworthiness to the prejudice of petitioners’ substantial rights. The two issues stand on somewhat different grounds.
The request by the accused to order production of Marshall’s earlier statements was cast in terms of obtaining access to documentary evidence rather than an offer
In the absence of specific legislation, questions of this nature are governed “by the principles of the common law as they may be interpreted by the courts of the United States in the light of reason and experience.” 6 Apparently, earlier common law did not permit the accused to require production of such documents. 7 Some state jurisdictions still recognize no comprehensive right to see documents in the hands of the prosecution merely because they might aid in the preparation or presentation of the defense. 8 We need not consider such broad doctrines in order to resolve this case, which deals with a limited and definite category of documents to which the holdings of this opinion are likewise confined.
By proper cross-examination, defense counsel laid a foundation for his demand by showing that the documents were in existence, were in possession of the Government, were made by the Government’s witness under examination, were contradictory of his present testimony, and that the contradiction was as to relevant, important and material matters which directly bore on the main
Despite some contrary holdings on which the courts below may have relied, we think their reasoning is outweighed by that of highly respectable authority in state and lower federal courts in support of the view that an accused is entitled to the production of such documents. 11 Indeed, we would find it hard to withstand the force of Judge Cooley’s observation in a similar situation that “The State has no interest in interposing any obstacle to the disclosure of the facts, unless it is interested in convicting accused parties on the testimony of untrustworthy persons.” 12 In the light of our reason and experience, the better rule is that upon the foundation that was laid the court should have overruled the objections which the Government advanced and ordered production of the documents.
The Court of Appeals affirmed on the ground that Marshall's admission, on cross-examination, of the implicit contradiction between the documents and his testimony removed the need for resort to the statements and the admission was all the accused were entitled to demand. We cannot agree. We think that an admission that a contradiction is contained in a writing should not bar admission of the document itself in evidence, providing
The second effort to impeach Marshall was to offer parts already quoted from the transcript of proceedings
We believe, moreover, that the combination of these two errors was sufficiently prejudicial to require reversal. The Government, in its brief, argues strongly for the widest sort of discretion in the trial judge in these matters and urges that even if we find error or irregularity we disregard it as harmless

We note in passing that the rules relating to impeachment by prior self-contradiction, which provide that such contradiction may be shown only on a matter material to the substantive issues of the trial, contain within themselves a guarantee against multiplication and confusion of issues. Therefore the discretion of the trial judge in excluding otherwise admissible evidence of this type is not as wide as it is in the vague and amorphous area of cross-examination of character witnesses.

The best evidence rule is usually relied upon by one opposing admission, on the ground that the evidence offered by the proponent does not meet its standards. Its merit as an assurance of the most accurate record possible commends its extension to this unique situation where it is the proponent who seeks to rely on it.
Fed. Rules Crim. Proc., 52 admonishes us that “Any error, defect, irregularity or variance which does not affect substantial rights shall be disregarded.”
