Argued Nov. 5, 1985.
Decided Feb. 26, 1986.
(Cite as: 475 U.S. 157, 106 S.Ct. 988)
Criminal client, whose attorney advised him that he would seek to withdraw from
representation if he insisted on committing perjury, petitioned for habeas corpus
relief from his state conviction for murder on the ground of ineffectiveness
of counsel. The United States District Court for the Southern District of Iowa,
William C. Stuart, Chief Judge, denied the petition, and client appealed. The
Court of Appeals for the Eighth Circuit, McMillian, Circuit Judge, 744
reversed, and, 750
denied motion for rehearing on bond. Certiorari was granted. The Supreme Court,
Chief Justice Burger, held that right to assistance of counsel was not violated
by attorney who refused to cooperate in presenting perjured testimony.
Justice Brennan filed an opinion concurring in the judgment.
Justice Blackmun filed an opinion concurring in the judgment in which Justices Brennan, Marshall, and Stevens, joined.
Justice Stevens filed an opinion concurring in the judgment.

 We granted certiorari to decide whether the Sixth Amendment right of a criminal defendant to assistance of counsel is violated when an attorney refuses to cooperate with the defendant in presenting perjured testimony at his trial. [FN1]
FN1. Although courts universally condemn an attorney's assisting in presenting perjury, Courts of Appeals have taken varying approaches on how to deal with a client's insistence on presenting perjured testimony. The Seventh Circuit, for example, has held that an attorney's refusal to call the defendant as a witness did not render the conviction constitutionally infirm where the refusal to call the defendant was based on the attorney's belief that the defendant would commit perjury. United States v. Curtis, 742 F.2d 1070 (1984). The Third Circuit found a violation of the Sixth Amendment where the attorney could not state any basis for her belief that defendant's proposed alibi testimony was perjured. United States ex rel. Wilcox v. Johnson, 555 F.2d 115 (1977). See also Lowery v. Cardwell, 575 F.2d 727 (CA9 1978) (withdrawal request in the middle of a bench trial, immediately following defendant's testimony).*160 I
Whiteside was convicted of second-degree murder by a jury verdict which was affirmed by the Iowa courts. The killing took place on February 8, 1977, in Cedar Rapids, Iowa. Whiteside and two others went to one Calvin Love's apartment late that night, seeking marihuana. Love was **991 in bed when Whiteside and his companions arrived; an argument between Whiteside and Love over the marihuana ensued. At one point, Love directed his girlfriend to get his "piece," and at another point got up, then returned to his bed. According to Whiteside's testimony, Love then started to reach under his pillow and moved toward Whiteside. Whiteside stabbed Love in the chest, inflicting a fatal wound.
Whiteside was charged with murder, and when counsel was appointed he objected to the lawyer initially appointed, claiming that he felt uncomfortable with a lawyer who had formerly been a prosecutor. Gary L. Robinson was then appointed and immediately began an investigation. Whiteside gave him a statement that he had stabbed Love as the latter "was pulling a pistol from underneath the pillow on the bed." Upon questioning by Robinson, however, Whiteside indicated that he had not actually seen a gun, but that he was convinced that Love had a gun. No pistol was found on the premises; shortly after the police search following the stabbing, which had revealed no weapon, the victim's family had removed all of the victim's possessions from the apartment. Robinson interviewed Whiteside's companions who were present during the stabbing, and none had seen a gun during the incident. Robinson advised Whiteside that the existence of a gun was not necessary to establish the claim of self-defense, and that only a reasonable belief that the victim had a gun nearby was necessary even though no gun was actually present.
Until shortly before trial, Whiteside consistently stated to Robinson that he had not actually seen a gun, but that he was *161 convinced that Love had a gun in his hand. About a week before trial, during preparation for direct examination, Whiteside for the first time told Robinson and his associate Donna Paulsen that he had seen something "metallic" in Love's hand. When asked about this, Whiteside responded:
"[I]n Howard Cook's case there was a gun. If I don't say I saw a gun, I'm dead."
Robinson told Whiteside that such testimony would be perjury and repeated that it was not necessary to prove that a gun was available but only that Whiteside reasonably believed that he was in danger. On Whiteside's insisting that he would testify that he saw "something metallic" Robinson told him, according to Robinson's testimony:
"[W]e could not allow him to [testify falsely] because that would be perjury, and as officers of the court we would be suborning perjury if we allowed him to do it; ... I advised him that if he did do that it would be my duty to advise the Court of what he was doing and that I felt he was committing perjury; also, that I probably would be allowed to attempt to impeach that particular testimony." App. to Pet. for Cert. A-85.
Robinson also indicated he would seek to withdraw from the representation if Whiteside insisted on committing perjury. [FN2]
FN2. Whiteside's version of the events at this pretrial meeting is considerably more cryptic:
"Q. And as you went over the questions, did the two of you come into conflict with regard to whether or not there was a weapon?
"A. I couldn't--I couldn't say a conflict. But I got the impression at one time that maybe if I didn't go along with--with what was happening, that it was no gun being involved, maybe that he will pull out of my trial." App. to Pet. for Cert. A-70.
Whiteside testified in his own defense at trial and stated that he "knew" that Love had a gun and that he believed Love was reaching for a gun and he had acted swiftly in self-defense. On cross-examination, he admitted that he had not *162 actually seen a gun in Love's hand. Robinson presented evidence that Love had been seen with a sawed-off shotgun on other occasions, that the police search of the apartment may have been careless, and that the victim's family had removed everything from the apartment shortly after the crime. Robinson presented this evidence to show a basis **992 for Whiteside's asserted fear that Love had a gun.
The jury returned a verdict of second-degree murder, and Whiteside moved for a new trial, claiming that he had been deprived of a fair trial by Robinson's admonitions not to state that he saw a gunor "something metallic." The trial court held a hearing, heard testimony by Whiteside and Robinson, and denied the motion. The trial court made specific findings that the facts were as related by Robinson.
The Supreme Court of Iowa affirmed respondent's conviction. State v. Whiteside, 272 N.W.2d 468 (1978). That court held that the right to have counsel present all appropriate defenses does not extend to using perjury, and that an attorney's duty to a client does not extend to assisting a client in committing perjury. Relying on DR 7-102(A)(4) of the Iowa Code of Professional Responsibility for Lawyers, which expressly prohibits an attorney from using perjured testimony, and Iowa Code § 721.2 (now Iowa Code § 720.3 (1985)), which criminalizes subornation of perjury, the Iowa court concluded that not only were Robinson's actions permissible, but were required. The court commended "both Mr. Robinson and Ms. Paulsen for the high ethical manner in which this matter was handled."
Whiteside then petitioned for a writ of habeas corpus in the United States District Court for the Southern District of Iowa. In that petition Whiteside alleged that he had been denied effective assistance of counsel and of his right to present a defense by Robinson's refusal to allow him to testify as he had proposed. The District Court denied the writ. Accepting the state trial court's factual finding that *163 Whiteside's intended testimony would have been perjurious, it concluded that there could be no grounds for habeas relief since there is no constitutional right to present a perjured defense.
The United States Court of Appeals for the Eighth Circuit reversed and directed that the writ of habeas corpus be granted. Whiteside v. Scurr, 744 F.2d 1323 (1984). . The petition for rehearing en banc was denied, with Judges Gibson, Ross, Fagg, and Bowman dissenting. Whiteside v. Scurr, 750 F.2d 713 (1984). We granted certiorari, 471 U.S. 1014, 105 S.Ct. 2016, 85 L.Ed.2d 298 (1985), and we reverse. ... *164 II
In Strickland v. Washington, we held that to obtain relief by way of federal habeas corpus on a claim of a deprivation of effective assistance of counsel under the Sixth Amendment, the movant must establish both serious attorney error and prejudice. To show such error, it must be established that the assistance rendered by counsel was constitutionally deficient *165 in that "counsel made errors so serious that counsel was not functioning as 'counsel' guaranteed the defendant by the Sixth Amendment." Strickland, 466 U.S., at 687, 104 S.Ct., at 2064. To show prejudice, it must be established that the claimed lapses in counsel's performance rendered the trial unfair so as to "undermine confidence in the outcome" of the trial. Id., at 694, 104 S.Ct., at 2068.
In Strickland, we acknowledged that the Sixth Amendment does not require any particular response by counsel to a problem that may arise. Rather, the Sixth Amendment inquiry is into whether the attorney's conduct was "reasonably effective." To counteract the natural tendency to fault an unsuccessful defense, a court reviewing a claim of ineffective assistance must "indulge a strong presumption that counsel's conduct falls within the wide range of reasonable professional assistance." Id., at 689, 104 S.Ct., at 2066. In giving shape to the perimeters of this range of reasonable professional assistance, Strickland mandates that
"[p]revailing norms of practice as reflected in American Bar Association Standards and the like, ... are guides to determining what is reasonable, but they are only guides." Id., at 688, 104 S.Ct., at 2065.
 Under the Strickland standard, breach of an ethical standard does not necessarily make out a denial of the Sixth Amendment guarantee of assistance of counsel. When examining attorney conduct, a court must be careful not to narrow the wide range of conduct acceptable under the Sixth Amendment so restrictively as to constitutionalize particular standards of professional conduct and thereby intrude into the state's proper authority to define and apply the standards of professional conduct applicable to those it admits to practice in its courts. In some future case challenging attorney conduct in the course of a state-court trial, we may need to define with greater precision the weight to be given to recognized canons of ethics, the standards established by the state in statutes or professional codes, and the Sixth Amendment, *166 in defining the proper **994 scope and limits on that conduct. Here we need not face that question, since virtually all of the sources speak with one voice.
We turn next to the question presented: the definition of the range of "reasonable professional" responses to a criminal defendant client who informs counsel that he will perjure himself on the stand. We must determine whether, in this setting, Robinson's conduct fell within the wide range of professional responses to threatened client perjury acceptable under the Sixth Amendment.
In Strickland, we recognized counsel's duty of loyalty and his "overarching duty to advocate the defendant's cause." Ibid. Plainly, that duty is limited to legitimate, lawful conduct compatible with the very nature of a trial as a search for truth. Although counsel must take all reasonable lawful means to attain the objectives of the client, counsel is precluded from taking steps or in any way assisting the client in presenting false evidence or otherwise violating the law. This principle has consistently been recognized in most unequivocal terms by expositors of the norms of professional conduct since the first Canons of Professional Ethics were adopted by the American Bar Association in 1908. The 1908 Canon 32 provided:
"No client, corporate or individual, however powerful, nor any cause, civil or political, however important, is entitled to receive nor should any lawyer render any service or advice involving disloyalty to the law whose ministers we are, or disrespect of the judicial office, which we are bound to uphold, or corruption of any person or persons exercising a public office or private trust, or deception or betrayal of the public.... He must ... observe and advise his client to observe the statute law...."
*167 Of course, this Canon did no more than articulate centuries of accepted standards of conduct. Similarly, Canon 37, adopted in 1928, explicitly acknowledges as an exception to the attorney's duty of confidentiality a client's announced intention to commit a crime:
"The announced intention of a client to commit a crime is not included within the confidences which [the attorney] is bound to respect."
These principles have been carried through to contemporary codifications [FN4] of an attorney's professional responsibility. Disciplinary Rule 7-102 of the Model Code of Professional Responsibility (1980), entitled "Representing a Client Within the Bounds of the Law," provides:
FN4. There currently exist two different codifications of uniform standards of professional conduct. The Model Code of Professional Responsibility was originally adopted by the American Bar Association in 1969, and was subsequently adopted (in many cases with modification) by nearly every state. The more recent Model Rules of Professional Conduct were adopted by the American Bar Association in 1983. Since their promulgation by the American Bar Association, the Model Rules have been adopted by 11 States: Arizona, Arkansas, Delaware, Minnesota, Missouri, Montana, Nevada, New Hampshire, New Jersey, North Carolina, and Washington. See 1 ABA/BNA Lawyers' Manual on Professional Conduct 334 (1984-1985) (New Jersey); id., at 445 (Arizona); id., at 855 (Montana, Minnesota); id., at 924 (Missouri); id., at 961 (Delaware, Washington); id., at 1026 (North Carolina); id., at 1127 (Arkansas); 2 id., at 14 (1986) (New Hampshire, Nevada). Iowa is one of the States that adopted a form of the Model Code of Professional Responsibility, but has yet to adopt the Model Rules. See Iowa Code of Professional Responsibility for Lawyers (1985).
"(A) In his representation of a client, a lawyer shall not:
* * *
"(4) Knowingly use perjured testimony or false evidence.
* * *
"(7) Counsel or assist his client in conduct that the lawyer knows to be illegal or fraudulent."
*168 This provision has been adopted by Iowa, and is binding on all lawyers who appear in its courts. See Iowa Code of Professional Responsibility for Lawyers (1985). The more recent Model Rules of **995 Professional Conduct (1983) similarly admonish attorneys to obey all laws in the course of representing a client:
"RULE 1.2 Scope of Representation
* * *
"(d) A lawyer shall not counsel a client to engage, or assist a client, in conduct that the lawyer knows is criminal or fraudulent...."
Both the Model Code of Professional Responsibility and the Model Rules of Professional Conduct also adopt the specific exception from the attorney-client privilege for disclosure of perjury that his client intends to commit or has committed. DR 4-101(C)(3) (intention of client to commit a crime); Rule 3.3 (lawyer has duty to disclose falsity of evidence even if disclosure compromises client confidences). Indeed, both the Model Code and the Model Rules do not merely authorize disclosure by counsel of client perjury; they require such disclosure. See Rule 3.3(a)(4); DR 7-102(B)(1); Committee on Professional Ethics and Conduct of Iowa State Bar Assn. v. Crary, 245 N.W.2d 298 (Iowa 1976).
These standards confirm that thelegal profession has accepted that an attorney's ethical duty to advance the interests of his client is limited by an equally solemn duty to comply with the law and standards of professional conduct; it specifically ensures that the client may not use false evidence. [FN5] This special duty of an attorney to prevent and disclose*169 frauds upon the court derives from the recognition that perjury is as much a crime as tampering with witnesses or jurors by way of promises and threats, and undermines the administration of justice. See 1 W. Burdick, Law of Crime §§ 293, 300, 318-336 (1946).
FN5. The brief of amicus American Bar Association, which supports petitioner, makes this point, referring to the history of codes of professional conduct which it has promulgated. The preamble to the most current version of the ethical standards recognizes the difficult choices that may confront an attorney who is sensitive to his concurrent duties to his client and to the legal system:
"Within the framework of these Rules many difficult issues of professional discretion can arise. Such issues must be resolved through the exercise of sensitive professional and moral judgment guided by the basic principles underlying the Rules." Preamble, Model Rules of Professional Conduct, p. 10 (1983).
The offense of perjury was a crime recognized at common law, id., at p. 475, and has been made a felony in most states by statute, including Iowa. Iowa Code § 720.2 (1985). See generally 4 C. Torcia, Wharton's Criminal Law § 631 (14th ed. 1981). An attorney who aids false testimony by questioning a witness when perjurious responses can be anticipated risks prosecution for subornation of perjury under Iowa Code § 720.3 (1985).
It is universally agreed that at a minimum the attorney's first duty when confronted with a proposal for perjurious testimony is to attempt to dissuade the client from the unlawful course of conduct. Model Rules of Professional Conduct, Rule 3.3, Comment; Wolfram, Client Perjury, 50 S.Cal.L.Rev. 809, 846 (1977). A statement directly in point is found in the commentary to the Model Rules of Professional Conduct under the heading "False Evidence":
"When false evidence is offered by the client, however, a conflict may arise between the lawyer's duty to keep the client's revelations confidential and the duty of candor to the court. Upon ascertaining that material evidence is false, the lawyer should seek to persuade the client that the evidence should not be offered or, if it has been offered, that its false character should immediately be disclosed." Model Rules of Professional Conduct, Rule 3.3, Comment (1983) (emphasis added).
*170 The commentary thus also suggests that an attorney's revelation of his client's perjury to the court is a professionally responsible and acceptable response to the conduct of a client who has actually given perjured testimony. Similarly, the Model Rules and the commentary, as well as the Code of Professional Responsibility **996 adopted in Iowa, expressly permit withdrawal from representation as an appropriate response of an attorney when the client threatens to commit perjury. Model Rules of Professional Conduct, Rule 1.16(a)(1), Rule 1.6, Comment (1983); Code of Professional Responsibility, DR 2-110(B), (C) (1980). Withdrawal of counsel when this situation arises at trial gives rise to many difficult questions including possible mistrial and claims of double jeopardy. [FN6]
FN6. In the evolution of the contemporary standards promulgated by the American Bar Association, an early draft reflects a compromise suggesting that when the disclosure of intended perjury is made during the course of trial, when withdrawal of counsel would raise difficult questions of a mistrial holding, counsel had the option to let the defendant take the stand but decline to affirmatively assist the presentation of perjury by traditional direct examination. Instead, counsel would stand mute while the defendant undertook to present the false version in narrative form in his own words unaided by any direct examination. This conduct was thought to be a signal at least to the presiding judge that the attorney considered the testimony to be false and was seeking to disassociate himself from that course. Additionally, counsel would not be permitted to discuss the known false testimony in closing arguments. See ABA Standards for Criminal Justice, Proposed Standard 4-7.7 (2d ed. 1980). Most courts treating the subject rejected this approach and insisted on a more rigorous standard, see, e.g., United States v. Curtis, 742 F.2d 1070 (CA7 1984); McKissick v. United States, 379 F.2d 754 (CA5 1967); Dodd v. Florida Bar, 118 So.2d 17, 19 (Fla.1960). The Eighth Circuit in this case and the Ninth Circuit have expressed approval of the "free narrative" standards. Whiteside v. Scurr, 744 F.2d 1323, 1331 (CA8 1984); Lowery v. Cardwell, 575 F.2d 727 (CA9 1978).
The Rule finally promulgated in the current Model Rules of Professional Conduct rejects any participation or passive role whatever by counsel in allowing perjury to be presented without challenge.
The essence of the brief amicus of the American Bar Association reviewing practices long accepted by ethical lawyers *171 is that under no circumstance may a lawyer either advocate or passively tolerate a client's giving false testimony. This, of course, is consistent with the governance of trial conduct in what we have long called "a search for truth." The suggestion sometimes made that "a lawyer must believe his client, not judge him" in no sense means a lawyer can honorably be a party to or in any way give aid to presenting known perjury.
 Considering Robinson's representation of respondent in light of these accepted norms of professional conduct, we discern no failure to adhere to reasonable professional standards that would in any sense make out a deprivation of the Sixth Amendment right to counsel. Whether Robinson's conduct is seen as a successful attempt to dissuade his client from committing the crime of perjury, or whether seen as a "threat" to withdraw from representation and disclose the illegal scheme, Robinson's representation of Whiteside falls well within accepted standards of professional conduct and the range of reasonable professional conduct acceptable under Strickland.
The Court of Appeals assumed for the purpose of the decision that Whiteside would have given false testimony had counsel not intervened; its opinion denying a rehearing en banc states:
"[W]e presume that appellant would have testified falsely.
* * *
"... Counsel's actions prevented [Whiteside] from testifying falsely. We hold that counsel's action deprived appellant of due process and effective assistance of counsel.
* * *
"Counsel's actions also impermissibly compromised appellant's right to testify in his own defense by conditioning continued representation by counsel and confidentiality *172 upon appellant's restricted testimony." 750 F.2d, at 714-715.
While purporting to follow Iowa's highest court "on all questions of state law," 744 F.2d., at 1330, the Court of Appeals reached its conclusions on the basis of federal **997 constitutional due process and right to counsel.
The Court of Appeals' holding that Robinson's "action deprived [Whiteside] of due process and effective assistance of counsel" is not supported by the record since Robinson's action, at most, deprived Whiteside of his contemplated perjury. Nothing counsel did in any way undermined Whiteside's claim that he believed the victim was reaching for a gun. Similarly, the record gives no support for holding that Robinson's action "also impermissibly compromised [Whiteside's] right to testify in his own defense by conditioning continued representation ... and confidentiality upon [Whiteside's] restricted testimony." The record in fact shows the contrary: (a) that Whiteside did testify, and (b) he was "restricted" or restrained only from testifying falsely and was aided by Robinson in developing the basis for the fear that Love was reaching for a gun. Robinson divulged no client communications until he was compelled to do so in response to Whiteside's post-trial challenge to the quality of his performance. We see this as a case in which the attorney successfully dissuaded the client from committing the crime of perjury.
Paradoxically, even while accepting the conclusion of the Iowa trial court that Whiteside's proposed testimony would have been a criminal act, the Court of Appeals held that Robinson's efforts to persuade Whiteside not to commit that crime were improper, first, as forcing an impermissible choice between the right to counsel and the right to testify; and, second, as compromising client confidences because of Robinson's threat to disclose the contemplated perjury. [FN7]
FN7. The Court of Appeals also determined that Robinson's efforts to persuade Whiteside to testify truthfully constituted an impermissible threat to testify against his own client. We find no support for a threat to testify against Whiteside while he was acting as counsel. The record reflects testimony by Robinson that he had admonished Whiteside that if he withdrew he "probably would be allowed to attempt to impeach that particular testimony," if Whiteside testified falsely. The trial court accepted this version of the conversation as true.
 *173 Whatever the scope of a constitutional right to testify, it is elementary that such a right does not extend to testifying falsely. In Harris v. New York, we assumed the right of an accused to testify "in his own defense, or to refuse to do so" and went on to hold:
"[T]hat privilege cannot be construed to include the right to commit perjury. See United States v. Knox, 396 U.S. 77 [90 S.Ct. 363, 24 L.Ed.2d 275] (1969); cf. Dennis v. United States, 384 U.S. 855 [86 S.Ct. 1840, 16 L.Ed.2d 973] (1966). Having voluntarily taken the stand, petitioner was under an obligation to speak truthfully...." 401 U.S., at 225, 91 S.Ct., at 645.
In Harris we held the defendant could be impeached by prior contrary statements which had been ruled inadmissible under Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966). Harris and other cases make it crystal clear that there is no right whatever--constitutional or otherwise-- for a defendant to use false evidence. See also United States v. Havens, 446 U.S. 620, 626-627, 100 S.Ct. 1912, 1916-1917, 64 L.Ed.2d 559 (1980).
The paucity of authority on the subject of any such "right" may be explained by the fact that such a notion has never been responsibly advanced; the right to counsel includes no right to have a lawyer who will cooperate with planned perjury. A lawyer who would so cooperate would be at risk of prosecution for suborning perjury, and disciplinary proceedings, including suspension or disbarment.
Robinson's admonitions to his client can in no sense be said to have forced respondent into an impermissible choice between his right to counsel and his right to testify as he proposed for there was no permissible choice to testify falsely. For defense counsel to take steps to persuade a criminal defendant to testify truthfully, or to withdraw, deprives the defendant of neither his right to counsel nor the right to *174 testify **998 truthfully. In United States v. Havens, supra, we made clear that "when defendants testify, they must testify truthfully or suffer the consequences." Id., at 626, 100 S.Ct., at 1916. When an accused proposes to resort to perjury or to produce false evidence, one consequence is the risk of withdrawal of counsel.
On this record, the accused enjoyed continued representation within the bounds of reasonable professional conduct and did in fact exercise his right to testify; at most he was denied the right to have the assistance of counsel in the presentation of false testimony. Similarly, we can discern no breach of professional duty in Robinson's admonition to respondent that he would disclose respondent's perjury to the court. The crime of perjury in this setting is indistinguishable in substance from the crime of threatening or tampering with a witness or a juror. A defendant who informed his counsel that he was arranging to bribe or threaten witnesses or members of the jury would have no "right" to insist on counsel's assistance or silence. Counsel would not be limited to advising against that conduct. An attorney's duty of confidentiality, which totally covers the client's admission of guilt, does not extend to a client's announced plans to engage in future criminal conduct. See Clark v. United States, 289 U.S. 1, 15, 53 S.Ct. 465, 469, 77 L.Ed. 993 (1933). In short, the responsibility of an ethical lawyer, as an officer of the court and a key component of a system of justice, dedicated to a search for truth, is essentially the same whether the client announces an intention to bribe or threaten witnesses or jurors or to commit or procure perjury. No system of justice worthy of the name can tolerate a lesser standard.
The rule adopted by the Court of Appeals, which seemingly would require an attorney to remain silent while his client committed perjury, is wholly incompatible with the established standards of ethical conduct and the laws of Iowa and contrary to professional standards promulgated by that State. The position advocated by petitioner, on the contrary, *175 is wholly consistent with the Iowa standards of professional conduct and law, with the overwhelming majority of courts, [footnote omitted] and with codes of professional ethics. Since there has been no breach of any recognized professional duty, it follows that there can be no deprivation of the right to assistance of counsel under the Strickland standard.
 We hold that, as a matter of law, counsel's conduct complained of here cannot establish the prejudice required for relief under the second strand of the Strickland inquiry. Although a defendant need not establish that the attorney's deficient performance more likely than not altered the outcome in order to establish prejudice under Strickland, a defendant must show that "there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different." 466 U.S., at 694, 104 S.Ct., at 2068. According to Strickland, "[a] reasonable probability is a probability sufficient to undermine confidence in the outcome." Ibid. The Strickland Court noted that the "benchmark" of an ineffective-assistance claim is the fairness of the adversary proceeding, and that in judging prejudice and the likelihood of a different outcome, "[a] defendant has no entitlement to the luck of a lawless decisionmaker." Id., at 695, 104 S.Ct., at 2068.
Whether he was persuaded or compelled to desist from perjury, Whiteside has no valid claim that confidence in the result of his trial has been diminished by his desisting **999 from the contemplated perjury. Even if we were to assume that *176 the jury might have believed his perjury, it does not follow that Whiteside was prejudiced.
In his attempt to evade the prejudice requirement of Strickland, Whiteside relies on cases involving conflicting loyalties of counsel. In Cuyler v. Sullivan, 446 U.S. 335, 100 S.Ct. 1708, 64 L.Ed.2d 333 (1980), we held that a defendant could obtain relief without pointing to a specific prejudicial default on the part of his counsel, provided it is established that the attorney was "actively represent[ing] conflicting interests." Id., at 350, 100 S.Ct., at 1719.
Here, there was indeed a "conflict," but of a quite different kind; it was one imposed on the attorney by the client's proposal to commit the crime of fabricating testimony without which, as he put it, "I'm dead." This is not remotely the kind of conflict of interests dealt with in Cuyler v. Sullivan. Even in that case we did not suggest that all multiple representations necessarily resulted in an active conflict rendering the representation constitutionally infirm. If a "conflict" between a client's proposal and counsel's ethical obligation gives rise to a presumption that counsel's assistance was prejudicially ineffective, every guilty criminal's conviction would be suspect if the defendant had sought to obtain an acquittal by illegal means. Can anyone doubt what practices and problems would be spawned by such a rule and what volumes of litigation it would generate?
Whiteside's attorney treated Whiteside's proposed perjury in accord with professional standards, and since Whiteside's truthful testimony could not have prejudiced the result of his trial, the Court of Appeals was in error to direct the issuance of a writ of habeas corpus and must be reversed.
Justice BRENNAN, concurring in the judgment.
This Court has no constitutional authority to establish rules of ethical conduct for lawyers practicing in the state courts. Nor does the Court enjoy any statutory grant of jurisdiction over legal ethics.
*177 Accordingly, it is not surprising that the Court emphasizes that it "must be careful not to narrow the wide range of conduct acceptable under the Sixth Amendment so restrictively as to constitutionalize particular standards of professional conduct and thereby intrude into the state's proper authority to define and apply the standards of professional conduct applicable to those it admits to practice in its courts." Ante, at ----. I read this as saying in another way that the Court cannot tell the States or the lawyers in the States how to behave in their courts, unless and until federal rights are violated.
Unfortunately, the Court seems unable to resist the temptation of sharing with the legal community its vision of ethical conduct. But let there be no mistake: the Court's essay regarding what constitutes the correct response to a criminal client's suggestion that he will perjure himself is pure discourse without force of law. As Justice BLACKMUN observes, that issue is a thorny one, post, at ----, but it is not an issue presented by this case. Lawyers, judges, bar associations, students, and others should understand that the problem has not now been "decided."
I join Justice BLACKMUN's concurrence because I agree that respondent has failed to prove the kind of prejudice necessary to make out a claim under Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984).
Justice BLACKMUN, with whom Justice BRENNAN, Justice MARSHALL, and Justice STEVENS join, concurring in the judgment.
How a defense attorney ought to act when faced with a client who intends to commit perjury at trial has long been a controversial issue. [FN1] But I do not believe **1000 that a federal *178 habeas corpus case challenging a state criminal conviction is an appropriate vehicle for attempting to resolve this thorny problem. When a defendant argues that he was denied effective assistance of counsel because his lawyer dissuaded him from committing perjury, the only question properly presented to this Court is whether the lawyer's actions deprived the defendant of the fair trial which the Sixth Amendment is meant to guarantee. Since I believe that the respondent in this case suffered no injury justifying federal habeas relief, I concur in the Court's judgment.

On February 7, 1977, Emmanual Charles Whiteside stabbed Calvin Love to death. At trial, Whiteside claimed self-defense. On direct examination, he testified that Love's bedroom, where the stabbing had occurred, was "[v]ery much dark," App. 48, and that he had stabbed Love during an argument because he believed that Love was about to attack him with a weapon:
"Q. Did you think that Calvin had a gun?
"A. Most definitely I thought that.
"Q. Why did you think that?
"A. Because of Calvin's reputation, his brother's reputation, because of the prior conversation that Calvin and I had, I didn't have no other choice but to think he had a gun. And when he told his girl friend to give him his piece, I couldn't retreat." Id., at 50.
Whiteside's testimony was consistent with that of other witnesses who testified that the room was dark, and that Love *179 had asked his girlfriend to get his "piece" (which they all believed referred to a weapon). See, e.g., id., at 17-18, 20, 36-37, and 42-45. No gun, however, was ever found.
Whiteside, who had been charged with first-degree murder, was convicted of second-degree murder, and sentenced to 40 years' imprisonment. He moved for a new trial, contending that his court-appointed attorneys, Gary Robinson and Donna Paulsen, had improperly coerced his testimony. Whiteside now claimed that he had seen a gun, but had been prevented from testifying to this fact.
At an evidentiary hearing on this motion, Whiteside testified that he had told Robinson at their first meeting that he had seen a weapon in Love's hand. Some weeks later, Robinson informed Whiteside that the weapon could not be found and, according to Whiteside, told him to say only that he thought he had seen a gun, rather than that he in fact had seen one. Whiteside "got the impression at one time that maybe if I didn't go along with--with what was happening, that it was no gun being involved, maybe that he will pull out of my trial." App. to Pet. for Cert. A70.
Robinson's testimony contradicted Whiteside's. According to Robinson, Whiteside did not initially claim to have seen a gun, but rather claimed only that he was convinced Love had had one. Roughly a week before the trial, however, in the course of reviewing Whiteside's testimony, Whiteside "made reference to seeing something 'metallic'.... I don't think he ever did say a gun." Id., at A85:
"And at the end Donna asked him about that, because that was the first time it had ever been mentioned either to her or to myself. His response to that was, 'in Howard Cook's case there was a gun. If I don't say I saw a gun, I'm dead.' I explained to him at that time that it was not necessary that the gun be physically present for self-defense, one; two, that **1001 to say that would be perjury on his part because he had never at any time indicated that there was a gun ...; three, that we could not allow *180 him to do that ...; four, I advised him that if he did do that it would be my duty to advise the Court of what he was doing ...; also, that I probably would be allowed to attempt to impeach that particular testimony. I told him that there was no need for him to lie about what had happened, that he had a good and valid defense on the facts as he had related them to us, and we felt we could present a good self-defense case on the facts he had stated to us." Ibid.
Robinson acknowledged that Whiteside's claim of self-defense would have been stronger had the gun been found, but explained that at trial "we tried to create a gun," through testimony from people who had seen Love carrying a gun on other occasions, through a stipulation that Love had been convicted of possession of a weapon, and through suggestions made during cross-examination of the State's witnesses that the initial police search had been too cursory to discover the weapon and that Love's girlfriend had removed it from the apartment prior to a second, more thorough, search. Id., at A87-A88.
The trial court rejected Whiteside's motion for a new trial, "find[ing] the facts to be as testified to by Ms. Paulsen and Mr. Robinson." App. 57. The Iowa Supreme Court affirmed. State v. Whiteside, 272 N.W.2d 468 (1978).
Whiteside then sought federal habeas relief in the United States District Court for the Southern District of Iowa. The parties agreed to rest on the record made in the state-court proceedings. Chief Judge Stuart held that the trial judge's factual finding that Whiteside would have committed perjury had he testified at trial actually to having seen a gun was fairly supported by the record and thus entitled to a presumption of correctness. See 28 U.S.C. § 2254(d). Since Whiteside had no constitutional right to perjure himself, he had been denied neither a fair trial nor effective assistance of counsel. App. to Pet. for Cert. A41.
*181 The Court of Appeals for the Eighth Circuit reversed. Whiteside v. Scurr, 744 F.2d 1323 (1984). The court recognized that the issue before it was not whether Robinson had behaved ethically, [FN2] butrather whether Whiteside had been deprived of effective assistance of counsel. Id., at 1330. In the Court of Appeals' view, Robinson had breached the obligations of confidentiality and zealous advocacy imposed on defense counsel by the Sixth Amendment. In addition, the Court of Appeals concluded that Robinson's actions impermissibly compromised Whiteside's constitutional right to testify in his own behalf by conditioning continued representation and confidentiality on Whiteside's limiting his testimony.
FN2. The court stated: "That question is governed solely by the Iowa Code of Professional Responsibility, as it was in effect at the time of the trial in this case, and as it has been authoritatively interpreted by the Supreme Court of Iowa. The Supreme Court of Iowa is the last word on all questions of state law, and the Code of Professional Responsibility is a species of state law." 744 F.2d, at 1330.
Thus, the court declined to address the question whether Robinson's actions were either compelled or condoned by Iowa law.
The court recognized that, under Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984), a defendant must normally demonstrate both that his attorney's behavior was professionally unreasonable and that he was prejudiced by his attorney's unprofessional behavior. But it noted that Strickland v. Washington had recognized a "limited" presumption of prejudice when counsel is burdened by an actual conflict of interest that adversely affects his performance, see id., at 692, 104 S.Ct., at 2067, quoting Cuyler v. Sullivan, 446 U.S. 335, 348, 350, 100 S.Ct. 1708, 1718, 1719, 64 L.Ed.2d 333 (1980). Here, Whiteside had shown that Robinson's obligations under the Iowa Code of Professional Responsibility conflicted with his client's wishes, and his threat to testify against Whiteside had adversely affected **1002 Whiteside by "undermin[ing] the fundamental *182 trust between lawyer and client" necessary for effective representation. 744 F.2d, at 1330.
The District Court found that the trial judge's statement that "I find the facts to be as testified to by Ms. Paulsen and Mr. Robinson" was a factual finding that Whiteside "would have perjured himself if he had testified at trial that he actually saw a gun in his victim's hand." App. to Pet. for Cert. A42. This factual finding by the state court is entitled to a presumption of correctness under 28 U.S.C. § 2254(d), which Whiteside has not overcome.
In light of respondent's failure to show any cognizable prejudice, I see no need to "grade counsel's performance." Strickland v. Washington, 466 U.S., at 697, 104 S.Ct., at 2070. The only federal issue in this case is whether Robinson's behavior deprived Whiteside of the effective assistance of counsel; it is not whether Robinson's behavior conformed to any particular code of legal ethics.
Whether an attorney's response to what he sees as a client's plan to commit perjury violates a defendant's Sixth Amendment rights may depend on many factors: how certain the attorney is that the proposed testimony is false, the stage *189 of the proceedings at which the attorney discovers the plan, or the ways in which the attorney may be able to dissuade his client, to name just three. The complex interaction of factors, which is likely to vary from case to case, makes inappropriate a blanket rule that defense attorneys must reveal, or threaten to reveal, a client's anticipated perjury to the court. Except in the rarest of cases, attorneys who adopt "the role of the judge or jury to determine the facts," United States ex rel. Wilcox v. Johnson, 555 F.2d 115, 122 (CA3 1977), pose a danger of depriving their clients of the zealous and loyal advocacy required by the Sixth Amendment. [FN8]
FN8. A comparison of this case with Wilcox is illustrative. Here, Robinson testified in detail to the factors that led him to conclude that respondent's assertion he had seen a gun was false. See, e.g., Tr. 38-39, 43, 59 (July 29, 1977). The Iowa Supreme Court found "good cause" and "strong support" for Robinson's conclusion. State v. Whiteside, 272 N.W.2d 468, 471 (1978). Moreover, Robinson gave credence to those parts of Whiteside's account which, although he found them implausible and unsubstantiated, were not clearly false. See Tr. 52-53 (July 29, 1977). By contrast, in Wilcox, where defense counsel actually informed the judge that she believed her client intended to lie and where her threat to withdraw in the middle of the trial led the defendant not to take the stand at all, the Court of Appeals found "no evidence on the record of this case indicating that Mr. Wilcox intended to perjure himself," and characterized counsel's beliefs as "private conjectures about the guilt or innocence of [her] client." 555 F.2d, at 122.
**1006 I therefore am troubled by the Court's implicit adoption of a set of standards of professional responsibility for attorneys in state criminal proceedings. See ante, at 995-996. The States, of course, do have a compelling interest in the integrity of their criminal trials that can justify regulating the length to which an attorney may go in seeking his client's acquittal. But the American Bar Association's implicit suggestion in its brief amicus curiae that the Court find that the Association's Model Rules of Professional Conduct should govern an attorney's responsibilities is addressed to the wrong audience. It is for the States to decide how attorneys should conduct themselves in state criminal proceedings, and *190 this Court's responsibility extends only to ensuring that the restrictions a State enacts do not infringe a defendant's federal constitutional rights. Thus, I would follow the suggestion made in the joint brief amici curiae filed by 37 States at the certiorari stage that we allow the States to maintain their "differing approaches" to a complex ethical question. Brief for State of Indiana et al. as Amici Curiae 5. The signal merit of asking first whether a defendant has shown any adverse prejudicial effect before inquiring into his attorney's performance is that it avoids unnecessary federal interference in a State's regulation of its bar. Because I conclude that the respondent in this case failed to show such an effect, I join the Court's judgment that he is not entitled to federal habeas relief.
Justice STEVENS, concurring in the judgment.
Justice Holmes taught us that a word is but the skin of a living thought. A "fact" may also have a life of its own. From the perspective of an appellate judge, after a case has been tried and the evidence has been sifted by another judge, a particular fact may be as clear and certain as a piece of crystal or a small diamond. A trial lawyer, however, must often deal with mixtures of sand and clay. Even a pebble that seems clear enough at first glance may take on a different hue in a handful of gravel.
As we view this case, it appears perfectly clear that respondent intended to commit perjury, that his lawyer knew it, and that the lawyer had a duty--both to the court and to his client, for perjured testimony can ruin an otherwise meritorious case--to take extreme measures to prevent the perjury from occurring. The lawyer was successful and, from our unanimous and remote perspective, it is now pellucidly clear that the client suffered no "legally cognizable prejudice."
Nevertheless, beneath the surface of this case there are areas of uncertainty that cannot be resolved today. A lawyer's certainty that a change in his client's recollection is a *191 harbinger of intended perjury--as well as judicial review of such apparent certainty--should be tempered by the realization that, after reflection, the most honest witness may recall (or sincerely believe he recalls) details that he previously overlooked. Similarly, the post-trial review of a lawyer's pretrial threat to expose perjury that had not yet been committed--and, indeed, may have been prevented by the threat--is by no means the same as review of the way in which such a threat may actually have been carried out. Thus, one can be convinced--as I am--that this lawyer's actions were a proper way to provide his client with effective representation without confronting the much more difficult questions of what a lawyer must, should, or may do after his client has given testimony that the lawyer does not believe. The answer to such questions may well be colored by the particular circumstances attending the actual event and its aftermath.
Because Justice BLACKMUN has preserved such questions for another day, and because I do not understand him to imply **1007 any adverse criticism of this lawyer's representation of his client, I join his opinion concurring in the judgment.
