delivered the opinion of the Court.
A New York law confers upon every judge in a non-jury criminal trial the power to deny counsel any opportunity to make a summation of the evidence before the rendition of judgment. N. Y. Crim. Proc. Law § 320.20 *854(3) (c) (1971).1 In the case before us we are called upon to assess the constitutional validity of that law.
I
The appellant was brought to trial in the Supreme Court of Richmond County, N. Y., upon charges of attempted robbery in the first and third degrees and possession of a dangerous instrument.2 He waived a jury.
The trial began on a Thursday, and, after certain preliminaries, the balance of that day and most of Friday were spent on the case for the prosecution. The complaining witness, Allen Braxton, testified that the appellant had approached him outside his home in a Staten Island housing project at about six o’clock on the evening of September 15, 1971, and asked for money. He said that when he refused this demand, the appellant had swung a knife at him. On cross-examination, the appellant’s lawyer attempted to impeach the credibility of this evidence by demonstrating inconsistencies between Braxton’s testimony and other sworn statements that Braxton had previously made.3 The only other *855witness for the prosecution was the police officer who had arrested the appellant upon the complaint of Braxton. The officer testified that Braxton had reported the alleged incident to him, and that the appellant, when confronted by the officer later in the evening, had denied Braxton’s story and said that he had been working for a Mr. Taylor at the time of the alleged offense. The officer testified that he had then arrested the appellant and found a small knife in his pocket.4
At the close of the case for the prosecution, the court granted a defense motion to dismiss the charge of possession of a dangerous instrument on the ground that the knife in evidence was too small to qualify as a dangerous instrument under state law. The trial was then adjourned for the two-day weekend.
Proceedings did not actually resume until the following Monday afternoon. The first witness for the defense *856was Donald Taylor, who was the appellant’s employer. He testified that he recalled seeing the appellant on the job premises at about 5:30 p. m. on the day of the alleged offense. The appellant then took the stand and denied Braxton’s story. He said that he had been working on a refrigerator at his place of employment during the time of the alleged offense, and further testified that Braxton, a former neighbor, had threatened on several occasions to “fix” him for refusing to give Braxton money for wine and drugs.
At the conclusion of the case for the defense, counsel made a motion to dismiss the robbery charges. This motion was denied. The appellant’s lawyer then requested to “be heard somewhat on the facts.” The trial judge replied: “Under the new statute, summation is discretionary, and I choose not to hear summations.” The judge thereupon found the appellant guilty of attempted robbery in the third degree, and subsequently sentenced him to serve an indeterminate term of imprisonment with a maximum of four years. The conviction was affirmed without opinion by an intermediate appellate court.5 Leave to appeal to the New York Court of Appeals was denied. An appeal was then brought here, and we noted probable jurisdiction. 419 U. S. 893.
II
The Sixth Amendment guarantees to the accused in all criminal prosecutions the rights to a “speedy and *857public trial,” to an “impartial jury,” to notice of the “nature and cause of the accusation,” to be “confronted” with opposing witnesses, to “compulsory process” for defense witnesses, and to the “Assistance of Counsel.” 6 These fundamental rights are extended to a defendant in a state criminal prosecution through the Fourteenth Amendment.7
The decisions of this Court have not given to these constitutional provisions a narrowly literalistic construction. More specifically, the right to the assistance of counsel has been understood to mean that there can be no restrictions upon the function of counsel in defending a criminal prosecution in accord with the traditions of the adversary factfinding process that has been constitutionalized in the Sixth and Fourteenth Amendments. For example, in Ferguson v. Georgia, 365 U. S. 570, the Court held constitutionally invalid a state statute that, while permitting the defendant to make an unsworn statement to the court and jury, prevented defense counsel from eliciting the defendant’s testimony through direct examination. Similarly, in Brooks v. Tennessee, 406 U. S. 605, the Court found unconstitutional a state law *858that restricted the right of counsel to decide “whether, and when in the course of presenting his defense, the accused should take the stand.” Id., at 613. The right to the assistance of counsel has thus been given a meaning that ensures to the defense in a criminal trial the opportunity to participate fully and fairly in the adversary factfinding process.
There can be no doubt that closing argument for the defense is a basic element of the adversary factfinding process in a criminal trial. Accordingly, it has universally been held that counsel for the defense has a right to make a closing summation to the jury, no matter how strong the case for the prosecution may appear to the presiding judge.8 The issue has been considered less often *859in the context of a so-called bench trial. But the overwhelming weight of authority, in both federal and state courts, holds that a total denial of the opportunity for final argument in a non jury criminal trial is a denial of the basic right of the accused to make his' defense.9
One of many cases so holding was Yopps v. State, 228 Md. 204, 178 A. 2d 879 (1962). The defendant in that case, indicted for burglary, was tried by the court without a jury. The defendant in his testimony admitted being in the vicinity of the offense, but denied any involvement in the crime. At the conclusion of the testimony, the trial judge announced a judgment of guilty. Defense counsel objected, stating that he wished to present argument on the facts. But the trial judge refused to hear any argument on the ground that only a question of cred*860ibility was involved, and that therefore counsel’s argument would not change his mind. The Maryland Court of Appeals held that the trial court’s refusal to permit defense counsel to make a final summation violated the defendant’s right to the assistance of counsel under the State and Federal Constitutions:
“The Constitutional right of a defendant to be heard through counsel necessarily includes his right to have his counsel make a proper argument on the evidence and the applicable law in his favor, however simple, clear, unimpeached, and conclusive the evidence may seem, unless he has waived his right to such argument, or unless the argument is not within the issues in the case, and the trial court has no discretion to deny the accused such right.” Id., at 207, 178 A. 2d, at 881.
The widespread recognition of the right of the defense to make a closing summary of the evidence to the trier of the facts, whether judge or jury, finds solid support in history. In the 16th and 17th centuries, when notions of compulsory process, confrontation, and counsel were in their infancy, the essence of the English criminal trial was argument between the defendant and counsel for the Crown. Whatever other procedural protections may have been lacking, there was no absence of debate on the factual and legal issues raised in a criminal case.10 As the rights to compulsory process, to confrontation, and to counsel developed,11 the adversary system’s commit*861ment to argument was neither discarded nor diluted. Rather, the reform in procedure had the effect of shifting the primary function of argument to summation of the evidence at the close of trial, in contrast to the “fragmented” factual argument that had been typical of the earlier common law.12
*862It can hardly be questioned that closing argument serves to sharpen and clarify the issues for resolution by the trier of fact in a criminal case. For it is only after all the evidence is in that counsel for the parties are in a position to present their respective versions of the case as a whole. Only then can they argue the inferences to be drawn from all the testimony, and point out the weaknesses of their adversaries’ positions. And for the defense, closing argument is the last clear chance to persuade the trier of fact that there may be reasonable doubt of the defendant’s guilt. See In re Winship, 397 U. S. 358.
The very premise of our adversary system of criminal justice is that partisan advocacy on both sides of a case will best promote the ultimate objective that the guilty be convicted and the innocent go free. In a criminal trial, which is in the end basically a factfinding process, no aspect of such advocacy could be more important than the opportunity finally to marshal the evidence for each side before submission of the case to judgment.
This is not to say that closing arguments in a criminal case must be uncontrolled or even unrestrained. The presiding judge must be and is given great latitude in controlling the duration and limiting the scope of closing summations. He may limit counsel to a reasonable time and may terminate argument when continuation would be repetitive or redundant. He may ensure that argument does not stray unduly from the mark, or otherwise impede the fair and orderly conduct of the trial. In all these respects he must have broad discretion. See generally 5 R. Anderson, Wharton’s Criminal Law and Procedure §2077 (1957). Cf. American Bar Association Project on Standards for Criminal Justice, The Prosecution Function § 5.8, pp. 126-129, and the Defense Function § 7.8, pp. 277-282 (App. Draft 1971).
*863But there can be no justification for a statute that empowers a trial judge to deny absolutely the opportunity for any closing summation at all. The only conceivable interest served by such a statute is expediency. Yet the difference in any case between total denial of final argument and a concise but persuasive summation could spell the difference, for the defendant, between liberty and unjust imprisonment.13
Some cases may appear to the trial judge to be simple — open and shut — at the close of the evidence. And surely in many such cases a closing argument will, in the words of Mr. Justice Jackson, be “likely to leave [a] judge just where it found him.”14 But just as surely, there will be cases where closing argument may correct a premature misjudgment and avoid an otherwise erroneous verdict. And there is no certain way for a trial judge to identify accurately which cases these will be, until the judge has heard the closing summation of counsel.15
*864The present case is illustrative. This three-day trial was interrupted by an interval of more than two days— a period during which the judge's memory may well have dimmed, however conscientious a note-taker he may have been. At the conclusion of the evidence on the trial's final day, the appellant's lawyer might usefully have pointed to the direct conflict in the trial testimony of the only two prosecution witnesses concerning how. and when the appellant was found on the evening of the alleged offense.16 He might also have stressed the many inconsistencies, elicited on cross-examination, between the trial testimony of the complaining witness and his earlier sworn statements.17 He might reasonably have argued that the testimony of the appellant’s employer was entitled to greater credibility than that of the complaining witness, who, according to the appellant, had threatened to “fix” him because of personal differences in the past. There is no way to know whether these or any other appropriate arguments in summation might have affected the ultimate judgment in this case. The credibility assessment was solely for the trier of fact. But before that determination was made, the appellant, through counsel, had a right to be heard in summation of the evidence from the point of view most favorable to him.18
*865In denying the appellant this right under the authority of its statute, New York denied him the assistance of counsel that the Constitution guarantees. Accordingly, the judgment before us is vacated and the case is remanded for further proceedings not inconsistent with this opinion.
It is.so ordered.
Section 320.20 (3) (c) provides:
“The court may in its discretion permit the parties to deliver summations. If the court grants permission to one party, it must grant it to the other also. If both parties deliver summations, the defendant’s summation must be delivered first.”
By contrast, New York law explicitly grants a right to make a “closing statement” in every civil case. N. Y. Civ. Prac. Rule 4016 (1963).
N. Y. Penal Law §§ 110.00/160.15, 110.00/160.05, 265.05 (1975).
On cross-examination of Braxton, the appellant’s lawyer demonstrated the following inconsistencies: First, Braxton testified at trial that, after running into his house to evade the appellant, he did not look back outside to see where the appellant had gone; but before the grand jury, Braxton had said that, after entering his house, he had looked outside and the appellant was gone. Second, *855Braxton testified at trial that the knifeblade was shiny; but in his grand jury testimony he had said that he could not remember if it was shiny or not. Third, Braxton testified at trial that the appellant had asked him for money in a “soft” voice; but before the grand jury he had stated that the request for money was “kind of loud.” Fourth, Braxton testified at trial that the appellant had swung a blade at him once; but in the felony complaint filed the day after the alleged crime, he had stated that the appellant had swung a knife at him “a couple of times.”
There was a major inconsistency between the police officer’s testimony and that of Braxton. Braxton testified that he was walking down the street with the officer at about 6:45 p. m. when they came across the appellant. But the officer testified that he had searched for the appellant with Braxton until only about 6:30 p. m., when they had separated, and that about an hour later he had seen the appellant and Braxton on opposite sides of Broadway. Thus Braxton testified that he and the officer were together when they found the appellant about 6:45 p. m., while the officer’s testimony was that he had separated from Braxton about 6:30 p. m., and that he next saw Braxton and the appellant on opposite sides of a street at about 7:30 p. m.
The court subsequently certified that in affirming the judgment, it had rejected the appellant’s constitutional claims:
“Upon the appeal herein, there was presented and passed upon the following constitutional question, namely, whether relator’s rights under the Fourth, Sixth and Fourteenth Amendments were denied by the trial court’s application of paragraph (c) of subdivision 3 of CPL 320.20 to refuse appellant permission to deliver a summation. This court considered appellant’s said conviction and determined that none of his constitutional rights were violated.”
The Sixth Amendment provides:
“In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury ...[,] to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.”

Stephen has described the trial procedure in this period as a “long argument between the prisoner and the counsel for the Crown.” 1 J. Stephen, History of the Criminal Law of England 326 (1883). For a fuller description of the trial process in that period, see id,., at 325-326, 350.

Cf. Stephen, supra, n. 10, at 349.
In the Colonies, where a similar reform in criminal defendants’ rights occurred, common practice, if not right, apparently gave to the accused the opportunity to sum up his case in closing argument. For example, Zephaniah Swift, in an early colonial treatise on the law in Connecticut, wrote:
“When the exhibition of evidence is closed, the attorney for the state opens the argument, the counsel for the prisoner follow[s], the attorney for the state then closes the argument, and the chief justice then sums up the evidence in his charge delivered to the jury, in which he states in the most candid and impartial manner, the evidence and the law, and the arguments of the counsel for the state, as well as the prisoner. ...” 2 Z. Swift, A System of the Laws of the State of Connecticut 401 (1796).
With a lesser degree of certainty, a modern scholar concludes that in the trial of capital offenses in colonial Virginia, it was likely, but not certain, that the accused would be given an opportunity to make a dosing argument in summation at the end of the trial. See H. Rankin, Criminal Trial Proceedings in the General Court of Colonial Virginia 101 (1965).
In England, in 1865, the right of the defendant in a criminal trial to make a closing argument, either by himself or by counsel if he was represented, was given express statutory recognition: “[U]pon every Trial . . . whether the Prisoners ... or any of them, shall be defended by Counsel or not . . . such Prisoner . . . shall be entitled . . . when all the Evidence is concluded to sum up the Evidence respectively.” Criminal Procedure Act of 1865, 28 Viet., c. 18, § 2. This remains the rule in England. 10 Halsbury’s Laws of England § 777, pp. 422-423 (3d ed. 1955). See also T. Butler & M. Garsia, Archibold’s Pleading, Evidence and Practice in Criminal Cases, § 558 (37th ed. 1969). Cf. R. v. Wainwright, 13 Cox Cr. Cas. 171 (1875); R. v. Wickham, 55 Cr. App. R. 199 (1971) (noted at 1971 Crim. L. Rev. 233).
We deal in this case only with final argument or summation at the conclusion of the evidence in a criminal trial. Nothing said in this opinion is to be understood as implying the existence of a constitutional right to oral argument at any other stage of the trial or appellate process.
R. Jackson, The Struggle for Judicial Supremacy 301 (1941).
The contention has been made that, while a right to make closing argument should be recognized in a jury trial, there is insufficient justification for such a right in the context of a bench trial. This view rests on the premise that a judge, with legal training and experience, will be likely to see the case clearly, rendering argument superfluous, or to recognize that further illumination of the issues would be helpful, in which ease he would permit closing argument.
We find this contention unpersuasive. Judicial training and expertise, however it may enhance judgment, does not render memory or reasoning infallible. Moreover, in one important respect, closing argument may be even more important in a bench trial than in a trial by jury. As Mr. Justice Powell has observed, the “collective *864judgment” of the jury "tends to compensate for individual shortcomings and furnishes some assurance of a reliable decision.” Powell, Jury Trial of Crimes, 23 Wash. & Lee L. Rev. 1, 4 (1966). In contrast, the judge who tries a case presumably will reach his verdict with deliberation and contemplation, but must reach it without the stimulation of opposing viewpoints inherent in the collegial decision-making process of a jury.
See n. 4, supra.
See n. 3, supra.
A defendant who has exercised the right to conduct his own defense has, of course, the same right to make a closing argument. See Faretta v. California, ante, p. 806.
