The doctrine of qualified immunity protects government officials “from liability for civil damages insofar as their conduct does not violate clearly established statutory or constitutional rights of which a reasonable person would have known.” Harlow v. Fitzgerald, 457 U. S. 800, 818 (1982) . Qualified immunity balances two important interests—the need to hold public officials accountable when they exercise power irresponsibly and the need to shield officials from harassment, distraction, and liability when they perform their duties reasonably. The protection of qualified immunity applies regardless of whether the government official’s error is “a mistake of law, a mistake of fact, or a mistake based on mixed questions of law and fact.” Groh v. Ramirez, 540 U. S. 551, 567 (2004) (Kennedy, J., dissenting) (citing Butz v. Economou, 438 U. S. 478, 507 (1978) (noting that qualified immunity covers “mere mistakes in judgment, whether the mistake is one of fact or one of law”)).
Because qualified immunity is “an immunity from suit rather than a mere defense to liability … it is effectively lost if a case is erroneously permitted to go to trial.” Mitchell v. Forsyth, 472 U. S. 511, 526 (1985) (emphasis deleted). Indeed, we have made clear that the “driving force” behind creation of the qualified immunity doctrine was a desire to ensure that “ ‘insubstantial claims’ against government officials [will] be resolved prior to discovery.” Anderson v. Creighton, 483 U. S. 635 , n. 2 (1987). Accordingly, “we repeatedly have stressed the importance of resolving immunity questions at the earliest possible stage in litigation.” Hunter v. Bryant, 502 U. S. 224, 227 (1991) (per curiam).
In Saucier, 533 U. S. 194 , this Court mandated a two-step sequence for resolving government officials’ qualified immunity claims. First, a court must decide whether the facts that a plaintiff has alleged (see Fed. Rules Civ. Proc. 12(b)(6), (c)) or shown (see Rules 50, 56) make out a violation of a constitutional right. 533 U. S., at 201. Second, if the plaintiff has satisfied this first step, the court must decide whether the right at issue was “clearly established” at the time of defendant’s alleged misconduct. Ibid. Qualified immunity is applicable unless the official’s conduct violated a clearly established constitutional right. Anderson, supra, at 640.
Our decisions prior to Saucier had held that “the better approach to resolving cases in which the defense of qualified immunity is raised is to determine first whether the plaintiff has alleged a deprivation of a constitutional right at all.” County of Sacramento v. Lewis, 523 U. S. 833 , n. 5 (1998). Saucier made that suggestion a mandate. For the first time, we held that whether “the facts alleged show the officer’s conduct violated a constitutional right … must be the initial inquiry” in every qualified immunity case. 533 U. S., at 20 (emphasis added). Only after completing this first step, we said, may a court turn to “the next, sequential step,” namely, “whether the right was clearly established.” Ibid.
This two-step procedure, the Saucier Court reasoned, is necessary to support the Constitution’s “elaboration from case to case” and to prevent constitutional stagnation. Ibid. “The law might be deprived of this explanation were a court simply to skip ahead to the question whether the law clearly established that the officer's conduct was unlawful in the circumstances of the case.” Ibid.

In considering whether the Saucier procedure should be modified or abandoned, we must begin with the doctrine of stare decisis. Stare decisis “promotes the evenhanded, predictable, and consistent development of legal principles, fosters reliance on judicial decisions, and contributes to the actual and perceived integrity of the judicial process.” Payne v. Tennessee, 501 U. S. 808, 827 (1991) . Although “[w]e approach the reconsideration of [our] decisions … with the utmost caution,” “[s]tare decisis is not an inexorable command.” State Oil Co. v. Khan, 522 U. S. 3, 20 (1997) (internal quotation marks omitted). Revisiting precedent is particularly appropriate where, as here, a departure would not upset expectations, the precedent consists of a judge-made rule that was recently adopted to improve the operation of the courts, and experience has pointed up the precedent’s shortcomings.
“Considerations in favor of stare decisis are at their acme in cases involving property and contract rights, where reliance interests are involved; the opposite is true in cases … involving procedural and evidentiary rules” that do not produce such reliance. Payne, supra, at 828 (citations omitted). Like rules governing procedures and the admission of evidence in the trial courts, Saucier’s two-step protocol does not affect the way in which parties order their affairs. Withdrawing from Saucier’s categorical rule would not upset settled expectations on anyone’s part. See United States v. Gaudin, 515 U. S. 506, 521 (1995) .
Nor does this matter implicate “the general presumption that legislative changes should be left to Congress.” Khan, supra, at 20. We recognize that “considerations of stare decisis weigh heavily in the area of statutory construction, where Congress is free to change this Court’s interpretation of its legislation.” Illinois Brick Co. v. Illinois, 431 U. S. 720, 736 (1977) . But the Saucier rule is judge made and implicates an important matter involving internal Judicial Branch operations. Any change should come from this Court, not Congress.
Respondent argues that the Saucier procedure should not be reconsidered unless we conclude that its justification was “badly reasoned” or that the rule has proved to be “unworkable,” see Payne, supra, at 827, but those standards, which are appropriate when a constitutional or statutory precedent is challenged, are out of place in the present context. Because of the basis and the nature of the Saucier two-step protocol, it is sufficient that we now have a considerable body of new experience to consider regarding the consequences of requiring adherence to this inflexible procedure. This experience supports our present determination that a mandatory, two-step rule for resolving all qualified immunity claims should not be retained.
Lower court judges, who have had the task of applying the Saucier rule on a regular basis for the past eight years, have not been reticent in their criticism of Saucier’s “rigid order of battle.” See, e.g., Purtell v. Mason, 527 F. 3d 615, 622 (CA7 2008) (“This ‘rigid order of battle’ has been criticized on practical, procedural, and substantive grounds”); Leval, Judging Under the Constitution: Dicta About Dicta, 81 N. Y. U. L. Rev. 1249, 1275, 1277 (2006) (referring to Saucier’s mandatory two-step framework as “a new and mischievous rule” that amounts to “a puzzling misadventure in constitutional dictum”). And application of the rule has not always been enthusiastic. See Higazy v. Templeton, 505 F. 3d 161, 179, n. 19 (CA2 2007) (“We do not reach the issue of whether [plaintiff’s] Sixth Amendment rights were violated, because principles of judicial restraint caution us to avoid reaching constitutional questions when they are unnecessary to the disposition of a case”); Cherrington v. Skeeter, 344 F. 3d 631, 640 (CA6 2003) (“[I]t ultimately is unnecessary for us to decide whether the individual Defendants did or did not heed the Fourth Amendment command … because they are entitled to qualified immunity in any event”); Pearson v. Ramos, 237 F. 3d 881, 884 (CA7 2001) (“Whether [the Saucier] rule is absolute may be doubted”).
Members of this Court have also voiced criticism of the Saucier rule. See Morse v. Frederick, 551 U. S. ___, ___ (2007) (slip op., at 8) (Breyer, J., concurring in judgment in part and dissenting in part) (“I would end the failed Saucier experiment now”); Bunting v. Mellen, 541 U. S. 1019 (2004) (Stevens, J., joined by Ginsburg and Breyer, JJ., respecting denial of certiorari) (criticizing the “unwise judge-made rule under which courts must decide whether the plaintiff has alleged a constitutional violation before addressing the question whether the defendant state actor is entitled to qualified immunity”); Id., at 1025 (Scalia, J., joined by Rehnquist, C. J., dissenting from denial of certiorari) (“We should either make clear that constitutional determinations are not insulated from our review … or else drop any pretense at requiring the ordering in every case” (emphasis in original)); Brosseau v. Haugen, 543 U. S. 194, 201–202 (2004) (Breyer, J., joined by Scalia and Ginsburg, JJ., concurring) (urging Court to reconsider Saucier’s “rigid ‘order of battle,’ ” which “requires courts unnecessarily to decide difficult constitutional questions when there is available an easier basis for the decision (e.g., qualified immunity) that will satisfactorily resolve the case before the court”); Saucier, 533 U. S., at 210 (Ginsburg, J., concurring in judgment) (“The two-part test today’s decision imposes holds large potential to confuse”). Where a decision has “been questioned by Members of the Court in later decisions and [has] defied consistent application by the lower courts,” these factors weigh in favor of reconsideration. Payne, 501 U. S., at 829–830; see also Crawford v. Washington, 541 U. S. 36, 60 (2004) . Collectively, the factors we have noted make our present reevaluation of the Saucier two-step protocol appropriate.
