On reconsidering the procedure required in Saucier, we conclude that, while the sequence set forth there is often appropriate, it should no longer be regarded as mandatory. The judges of the district courts and the courts of appeals should be permitted to exercise their sound discretion in deciding which of the two prongs of the qualified immunity analysis should be addressed first in light of the circumstances in the particular case at hand.
A
Although we now hold that the Saucier protocol should not be regarded as mandatory in all cases, we continue to recognize that it is often beneficial. For one thing, there are cases in which there would be little if any conservation of judicial resources to be had by beginning and ending with a discussion of the “clearly established” prong. “[I]t often may be difficult to decide whether a right is clearly established without deciding precisely what the constitutional right happens to be.” Lyons v. Xenia, 417 F. 3d 565, 581 (CA6 2005) (Sutton, J., concurring). In some cases, a discussion of why the relevant facts do not violate clearly established law may make it apparent that in fact the relevant facts do not make out a constitutional violation at all. In addition, the Saucier Court was certainly correct in noting that the two-step procedure promotes the development of constitutional precedent and is especially valu-able with respect to questions that do not frequentlyarise in cases in which a qualified immunity defense is unavailable.

At the same time, however, the rigid Saucier procedure comes with a price. The procedure sometimes results in a substantial expenditure of scarce judicial resources on difficult questions that have no effect on the outcome of the case. There are cases in which it is plain that a constitutional right is not clearly established but far from obvious whether in fact there is such a right. District courts and courts of appeals with heavy caseloads are often understandably unenthusiastic about what may seem to be an essentially academic exercise.
Unnecessary litigation of constitutional issues also wastes the parties’ resources. Qualified immunity is “an immunity from suit rather than a mere defense to liability.” Mitchell, 472 U. S., at 526 (emphasis deleted). Saucier’s two-step protocol “disserve[s] the purpose of qualified immunity” when it “forces the parties to endure additional burdens of suit—such as the costs of litigating constitutional questions and delays attributable to resolving them—when the suit otherwise could be disposed of more readily.” Brief for Nat. Assn. of Criminal Defense Lawyers as Amicus Curiae 30.
Although the first prong of the Saucier procedure is intended to further the development of constitutional precedent, opinions following that procedure often fail to make a meaningful contribution to such development. For one thing, there are cases in which the constitutional question is so fact-bound that the decision provides little guidance for future cases. See Scott v. Harris, 550 U. S. 372, 388 (2007) (Breyer, J., concurring) (counseling against the Saucier two-step protocol where the question is “so fact dependent that the result will be confusion rather than clarity”); Buchanan v. Maine, 469 F. 3d 158, 168 (CA1 2006) (“We do not think the law elaboration purpose will be well served here, where the Fourth Amendment inquiry involves a reasonableness question which is highly idiosyncratic and heavily dependent on the facts”).
A decision on the underlying constitutional question in a §1983 damages action or a Bivens v. Six Unknown Fed. Narcotics Agents, 403 U. S. 388 (1971) ,1 action may have scant value when it appears that the question will soon be decided by a higher court. When presented with a constitutional question on which this Court had just granted certiorari, the Ninth Circuit elected to “bypass Saucier’s first step and decide only whether [the alleged right] was clearly established.” Motley v. Parks, 432 F. 3d 1072, 1078, and n. 5 (2005) (en banc). Similar considerations may come into play when a court of appeals panel confronts a constitutional question that is pending before the court en banc or when a district court encounters a constitutional question that is before the court of appeals.
A constitutional decision resting on an uncertain interpretation of state law is also of doubtful precedential importance. As a result, several courts have identified an “exception” to the Saucier rule for cases in which resolution of the constitutional question requires clarification of an ambiguous state statute. Egolf v. Witmer, 526 F. 3d 104, 109–111 (CA3 2008); accord, Tremblay v. McClellan, 350 F. 3d 195, 200 (CA1 2003); Ehrlich v. Glastonbury, 348 F. 3d 48, 57–60 (CA2 2003). Justifying the decision to grant qualified immunity to the defendant without first resolving, under Saucier’s first prong, whether the defendant’s conduct violated the Constitution, these courts have observed that Saucier’s “underlying principle” of encouraging federal courts to decide unclear legal questions in order to clarify the law for the future “is not meaningfully advanced … when the definition of constitutional rights depends on a federal court’s uncertain assumptions about state law.” Egolf, supra, at 110; accord, Tremblay, supra, at 200; Ehrlich, supra, at 58.
When qualified immunity is asserted at the pleading stage, the precise factual basis for the plaintiff’s claim or claims may be hard to identify. See Lyons, supra, at 582 (Sutton, J., concurring); Kwai Fun Wong v. United States, 373 F. 3d 952, 957 (CA9 2004); Mollica v. Volker, 229 F. 3d 366, 374 (CA2 2000). Accordingly, several courts have recognized that the two-step inquiry “is an uncomfortable exercise where … the answer [to] whether there was a violation may depend on a kaleidoscope of facts not yet fully developed” and have suggested that “[i]t may be that Saucier was not strictly intended to cover” this situation. Dirrane v. Brookline Police Dept., 315 F. 3d 65, 69–70 (CA1 2002); see also Robinette v. Jones, 476 F. 3d 585, 592, n. 8 (CA8 2007) (declining to follow Saucier because “the parties have provided very few facts to define and limit any holding” on the constitutional question).
There are circumstances in which the first step of the Saucier procedure may create a risk of bad decisionmaking. The lower courts sometimes encounter cases in which the briefing of constitutional questions is woefully inadequate. See Lyons, 417 F. 3d, at 582 (Sutton, J., concurring) (noting the “risk that constitutional questions may be prematurely and incorrectly decided in cases where they are not well presented”); Mollica, supra, at 374.
Although the Saucier rule prescribes the sequence in which the issues must be discussed by a court in its opinion, the rule does not—and obviously cannot—specify the sequence in which judges reach their conclusions in their own internal thought processes. Thus, there will be cases in which a court will rather quickly and easily decide that there was no violation of clearly established law before turning to the more difficult question whether the relevant facts make out a constitutional question at all. In such situations, there is a risk that a court may not devote as much care as it would in other circumstances to the decision of the constitutional issue. See Horne v. Coughlin, 191 F. 3d, 244, 247 (CA2 1999) (“Judges risk being insufficiently thoughtful and cautious in uttering pronouncements that play no role in their adjudication”); Leval 1278–1279.
Rigid adherence to the Saucier rule may make it hard for affected parties to obtain appellate review of constitutional decisions that may have a serious prospective effect on their operations. Where a court holds that a defendant committed a constitutional violation but that the violation was not clearly established, the defendant may face a difficult situation. As the winning party, the defendant’s right to appeal the adverse holding on the constitutional question may be contested. See Bunting, 541 U. S., at 1025 (Scalia, J., dissenting from denial of certiorari) (“The perception of unreviewability undermines adherence to the sequencing rule we . . . created” in Saucier); 2 see also Kalka v. Hawk, 215 F. 3d 90, 96, n. 9 (CADC 2000) (noting that “[n]ormally, a party may not appeal from a favorable judgment” and that the Supreme Court “has apparently never granted the certiorari petition of a party who prevailed in the appellate court”). In cases like Bunting, the “prevailing” defendant faces an unenviable choice: “compl[y] with the lower court’s advisory dictum without opportunity to seek appellate [or certiorari] review,” or “def[y] the views of the lower court, adher[e] to practices that have been declared illegal, and thus invit[e] new suits” and potential “punitive damages.” Horne, supra, at 247–248.
Adherence to Saucier’s two-step protocol departs from the general rule of constitutional avoidance and runs counter to the “older, wiser judicial counsel ‘not to pass on questions of constitutionality … unless such adjudication is unavoidable.’ ” Scott, 550 U. S., at 388 (Breyer, J., concurring) (quoting Spector Motor Service, Inc. v. McLaughlin, 323 U. S. 101, 105 (1944) ); see Ashwander v. TVA, 297 U. S. 288, 347 (1936) (Brandeis, J., concurring) (“The Court will not pass upon a constitutional question although properly presented by the record, if there is also present some other ground upon which the case may be disposed of ”).
In other analogous contexts, we have appropriately declined to mandate the order of decision that the lower courts must follow. For example, in Strickland v. Washington, 466 U. S. 668 (1984) , we recognized a two-part test for determining whether a criminal defendant was denied the effective assistance of counsel: The defendant must demonstrate (1) that his counsel’s performance fell below what could be expected of a reasonably competent practitioner; and (2) that he was prejudiced by that substandard performance. Id., at 687. After setting forth and applying the analytical framework that courts must use in evaluating claims of ineffective assistance of counsel, we left it to the sound discretion of lower courts to determine the order of decision. Id., at 697 (“Although we have discussed the performance component of an ineffectiveness claim prior to the prejudice component, there is no reason for a court deciding an ineffective assistance claim to approach the inquiry in the same order or even to address both components of the inquiry if the defendant makes an insufficient showing on one”).
In United States v. Leon, 468 U. S. 897 (1984) , we created an exception to the exclusionary rule when officers reasonably rely on a facially valid search warrant. Id., at 913. In that context, we recognized that a defendant challenging a search will lose if either: (1) the warrant issued was supported by probable cause; or (2) it was not, but the officers executing it reasonably believed that it was. Again, after setting forth and applying the analytical framework that courts must use in evaluating the good-faith exception to the Fourth Amendment warrant requirement, we left it to the sound discretion of the lower courts to determine the order of decision. Id., at 924, 925 (“There is no need for courts to adopt the inflexible practice of always deciding whether the officers’ conduct manifested objective good faith before turning to the question whether the Fourth Amendment has been violated”).
This flexibility properly reflects our respect for the lower federal courts that bear the brunt of adjudicating these cases. Because the two-step Saucier procedure is often, but not always, advantageous, the judges of the district courts and the courts of appeals are in the best position to determine the order of decisionmaking will best facilitate the fair and efficient disposition of each case.
C Any misgivings concerning our decision to withdraw from the mandate set forth in Saucier are unwarranted. Our decision does not prevent the lower courts from following the Saucier procedure; it simply recognizes that those courts should have the discretion to decide whether that procedure is worthwhile in particular cases. Moreover, the development of constitutional law is by no means entirely dependent on cases in which the defendant may seek qualified immunity. Most of the constitutional issues that are presented in §1983 damages actions and Bivens cases also arise in cases in which that defense is not available, such as criminal cases and §1983 cases against a municipality, as well as §1983 cases against individuals where injunctive relief is sought instead of or in addition to damages. See Lewis, 523 U. S., at 841, n. 5 (noting that qualified immunity is unavailable “in a suit to enjoin future conduct, in an action against a municipality, or in litigating a suppression motion”).
