Lynne KALINA, Petitioner,v.Rodney FLETCHER.
No. 96-792.
Supreme Court of the United States
Argued Oct. 7, 1997.
Decided Dec. 10, 1997.


Syllabus
*

Following customary practice, petitioner prosecuting attorney commenced criminal proceedings by filing three documents in Washington state court: (1) an unsworn information charging respondent with burglary; (2) an unsworn motion for an arrest warrant; and (3) a "Certification for Determination of Probable Cause,'' in which she summarized the evidence supporting the charge and swore to the truth of the alleged facts " [u]nder penalty of perjury.''  Based on the certification, the trial court found probable cause, and respondent was arrested and spent a day in jail.  Later, however, the charges against him were dismissed on the prosecutor's motion.  Focusing on two inaccurate factual statements in petitioner's certification, respondent sued her for damages under 42 U.S.C. §1983, alleging that she had violated his constitutional right to be free from unreasonable seizures.  The Federal District Court denied her motion for summary judgment, holding that she was not entitled to absolute prosecutorial immunity and that whether qualified immunity would  apply was a question of fact.  The Ninth Circuit affirmed.
Held: Section 1983 may create a damages remedy against a prosecutor for making false statements of fact in an affidavit supporting an application for an arrest warrant, since such conduct is not protected by the doctrine of absolute prosecutorial immunity. Pp. ___-___.
(a) Imbler v. Pachtman, 424 U.S. 409, 410, 430-431, 96 S.Ct. 984, 985, 994-996, 47 L.Ed.2d 128, and subsequent cases recognize that a criminal prosecutor is fully protected by absolute immunity when performing the traditional functions of an advocate, see, e.g., Buckley v. Fitzsimmons, 509 U.S. 259, 273, 113 S.Ct. 2606, 2615-2616, 125 L.Ed.2d 209, but is protected only by qualified immunity when he is not acting as an advocate, as where he functions as a complaining witness in presenting a judge with a complaint and supporting affidavit to establish probable cause for an arrest, see Malley v. Briggs, 475 U.S. 335, 340-341, 106 S.Ct. 1092, 1095-1096, 89 L.Ed.2d 271.  Under these cases, petitioner's activities in connection with the preparation and filing of the information against respondent and the motion for an arrest warrant clearly are protected by absolute immunity as part of the advocate's function.  Indeed, except for her act in personally attesting to the truth of the averments in the certification, the preparation and filing of that third document was protected as well. Pp. ___-___.
(b)  However, petitioner was acting as a complaining witness rather than a lawyer when she executed the certification " [u]nder penalty of perjury,'' and, insofar as she did so, §1983 may provide a remedy for respondent.  Since the Fourth Amendment requirement that arrest warrants be based "upon probable cause, supported by Oath or affirmation'' may not be satisfied by the mere filing of an unsworn information signed by the prosecutor, see, e.g., Gerstein v. Pugh, 420 U.S. 103, 117, 95 S.Ct. 854, 864-865, 43 L.Ed.2d 54, and since most Washington prosecutions are commenced by information, state law requires that an arrest warrant be supported by either an affidavit "or sworn testimony establishing the grounds for issuing the warrant.''  Petitioner's certification was designed to satisfy those requirements, but neither federal nor state law made it necessary for the prosecutor to make that certification.  Petitioner's argument that such execution was just one incident in a presentation that, viewed as a whole, was the work of an advocate is unavailing.  Although the exercise of an advocate's professional judgment informed petitioner's other actions, that judgment could not affect the truth or falsity of the factual statements contained in the certification.  Testifying about facts is the function of  the witness, not of the lawyer.  No matter how brief or succinct  it may be, the evidentiary component of an application for an arrest warrant is a distinct and essential predicate for a finding of probable cause.  Even when the person who makes the constitutionally required "Oath or affirmation'' is a lawyer, the only function that she performs is that of a witness. Petitioner's final argument, that denying her absolute immunity will have a "chilling effect'' on prosecutors in the administration of justice, is not supported by evidence and is unpersuasive. Pp. ___-___.
93 F.3d 653, affirmed.

1
The question presented is whether 42 U.S.C. §1983 creates a damages remedy against a prosecutor for making false statements of fact in an affidavit supporting an application for an arrest warrant, or whether, as she contends, such conduct is protected by "the doctrine of absolute prosecutorial immunity.''


2
* Petitioner is a Deputy Prosecuting Attorney for King County, Washington.  Following customary practice, on December 14, 1992, she commenced a criminal proceeding against respondent by filing three documents in the King County Superior Court.  Two of those documents-an information charging respondent with burglary and a motion for an arrest warrant-were unsworn pleadings.  The burglary charge was based on an alleged theft of computer equipment from a school.


3
Washington Criminal Rules require that an arrest warrant be supported by an affidavit or "sworn testimony establishing the grounds for issuing the warrant.''1 To satisfy that requirement, petitioner supported her motion with a third document-a "Certification for Determination of Probable Cause''-that summarized the evidence supporting the charge.  She personally vouched for the truth of the facts set forth in the certification under penalty of perjury.2 Based on petitioner's certification, the trial court found probable cause and ordered that an arrest warrant be issued.


4
Petitioner's certification contained two inaccurate factual statements.  After noting that respondent's fingerprints had been found on a glass partition in the school, petitioner stated that respondent had "never been associated with the school in any manner and did not have permission to enter the school or to take any property.''3 In fact, he had installed partitions on the premises and was authorized to enter the school.  She also stated that an employee of an electronics store had identified respondent "from a photo montage'' as the person who had asked for an appraisal of a computer stolen from the school.4 In fact,  the employee did not identify respondent.5


5
Respondent was arrested and spent a day in jail.  About a month later, the charges against him were dismissed on the prosecutor's motion.

6
Respondent brought this action under Rev. Stat. §1979, as amended, 42 U.S.C. §1983, seeking damages from petitioner based on her alleged violation of his constitutional right to be free from unreasonable seizures.  In determining immunity, we accept the allegations of respondent's complaint as true.  See Buckley v. Fitzsimmons, 509 U.S. 259, 261, 113 S.Ct. 2606, 2609, 125 L.Ed.2d 209 (1993).  Respondent's complaint focuses on the false statements made by the petitioner in the certification.6 Petitioner moved for summary judgment on the ground that the three documents that she filed to commence the criminal proceedings and to procure the arrest warrant were protected by "the doctrine of absolute prosecutorial immunity.''7 The District Court denied the motion, holding that she was not entitled to absolute immunity and that whether qualified immunity would apply was a question of fact.8 The Court of Appeals for the Ninth Circuit affirmed.


7
The Ninth Circuit first noted that under our decision in Malley v. Briggs, 475 U.S. 335, 106 S.Ct. 1092, 89 L.Ed.2d 271 (1986), "a police officer who secures an arrest warrant without probable cause cannot assert an absolute immunity defense,'' and then observed that petitioner's "actions in writing, signing and filing the declaration for an arrest warrant'' were "virtually identical to the police officer's actions in Malley.'' Fletcher v. Kalina, 93 F.3d 653, 655-656 (1996).  Relying on the functional approach endorsed in Buckley v. Fitzsimmons, the Court of Appeals concluded that "it would be "incongruous' to expose police to potential liability while protecting prosecutors for the same act.'' 93 F.3d, at 656.


8
The Court of Appeals acknowledged that the Sixth Circuit had reached a different result in Joseph v. Patterson, 795 F.2d 549, 555 (1986), cert. denied, 481 U.S. 1023, 107 S.Ct. 1910, 95 L.Ed.2d 516 (1987), a case that predated our decision in Buckley. Because we have never squarely addressed the question whether a prosecutor may be held liable for conduct in obtaining an arrest warrant, we granted certiorari to resolve the conflict. 519 U.S. ----, 117 S.Ct. 1079, 137 L.Ed.2d 214 (1997).  We now affirm.

9
Section 1983 is a codification of §1 of the Civil Rights Act of 1871.9 The text of the statute purports to create a damages remedy against every state official for the violation of any person's federal constitutional or statutory rights.10 The coverage of the statute is thus broader than the pre-existing common law of torts.  We have nevertheless recognized that Congress intended the statute to be construed in the light of common-law principles that were well settled at the time of its enactment.  See Tenney v. Brandhove, 341 U.S. 367, 71 S.Ct. 783, 95 L.Ed. 1019 (1951); Briscoe v. LaHue, 460 U.S. 325, 330, 103 S.Ct. 1108, 1112-1113, 75 L.Ed.2d 96 (1983).  Thus, we have examined common-law doctrine when identifying both the elements of the cause of action and the defenses available to state actors.


10
In Imbler v. Pachtman, 424 U.S. 409, 96 S.Ct. 984, 47 L.Ed.2d 128 (1976), we held that a former prisoner whose conviction had been set aside in collateral proceedings could not maintain a §1983 action against the prosecutor who had litigated the charges against him.  Relying in part on common-law precedent, and perhaps even more importantly on the policy considerations underlying that precedent, we concluded that "a state prosecuting attorney who acted within the scope of his duties in initiating and pursuing a criminal prosecution'' was not amenable to suit under §1983. Id., at 410, 96 S.Ct., at 985.


11
Liberally construed, Imbler's complaint included not only a charge that the prosecution had been wrongfully commenced, but also a charge that false testimony had been offered as well as a charge that exculpatory evidence had been suppressed.  His constitutional claims were thus broader than any specific common-law antecedent.  Nevertheless, relying on common-law decisions providing prosecutors with absolute immunity from tort actions based on claims that the decision to prosecute was malicious and  unsupported by probable cause,11 as well as from actions for defamation based on statements made during trial,12 we concluded  that the statute should be construed to provide an analogous defense against the claims asserted by Imbler.  The policy considerations that justified the common-law decisions affording  absolute immunity to prosecutors when performing traditional functions applied equally to statutory claims based on the conduct of the same functions.


12
Those considerations included both the interest in protecting the prosecutor from harassing litigation that would divert his time and attention from his official duties and the interest in enabling him to exercise independent judgment when "deciding which suits to bring and in conducting them in court.'' Id., at 424, 96 S.Ct., at 992.  The former interest would lend support to an immunity from all litigation against the occupant of the office whereas the latter is applicable only when the official is performing functions that require the exercise of prosecutorial discretion.  Our later cases have made it clear that it is the interest in protecting the proper functioning of the office, rather than the interest in protecting its occupant,  that is of primary importance.


13
In Imbler, we did not attempt to define the outer limits of the prosecutor's absolute immunity, but we did recognize that our rationale would not encompass some of his official activities. Thus, while we concluded that Pachtman's "activities were intimately associated with the judicial phase of the criminal process, and thus were functions to which the reasons for absolute immunity apply with full force,'' id., at 430, 96 S.Ct., at 995, we put to one side "those aspects of the prosecutor's responsibility that cast him in the role of an administrator or investigative officer rather than that of advocate.'' Id., at 430-431, 96 S.Ct., at 995.


14
Subsequent cases have confirmed the importance to the judicial process of protecting the prosecutor when serving as an advocate in judicial proceedings.  Thus, in Burns v. Reed, 500 U.S. 478, 111 S.Ct. 1934, 114 L.Ed.2d 547 (1991), after noting the consensus among the Courts of Appeals concerning prosecutorial conduct before grand juries, id., at 490, n. 6, 111 S.Ct., at 1941 n. 6, we held that the prosecutor's appearance in  court in support of an application for a search warrant and the presentation of evidence at that hearing were protected by absolute immunity. Id., at 492, 111 S.Ct., at 1942-43.  And in Buckley, we categorically stated that "acts undertaken by a prosecutor in preparing for the initiation of judicial proceedings or for trial, and which occur in the course of his role as an advocate for the State, are entitled to the protections of absolute immunity.'' 509 U.S., at 273, 113 S.Ct.,  at 2615.


15
In both of those cases, however, we found the defense unavailable when the prosecutor was performing a different function.  In Burns, the provision of legal advice to the police during their pretrial investigation of the facts was protected only by qualified, rather than absolute, immunity. 500 U.S., at 492-496, 111 S.Ct., at 1942-1945.  Similarly, in Buckley, the prosecutor was not acting as an advocate either when he held a press conference, 509 U.S., at 276-278, 113 S.Ct., at 2617-2618, or when he allegedly fabricated evidence concerning an unsolved crime.  With reference to the latter holding, we explained:


16
"There is a difference between the advocate's role in      evaluating evidence and interviewing witnesses as he prepares      for trial, on the one hand, and the detective's role in      searching for the clues and corroboration that might give him      probable cause to recommend that a suspect be arrested, on      the other hand.  When a prosecutor performs the investigative      functions normally performed by a detective or police      officer, it is "neither appropriate nor justifiable that, for      the same act, immunity should protect the one and  not the      other.' Hampton v. Chicago, 484 F.2d 602, 608 (C.A.7 1973)      (internal quotation marks omitted), cert. denied, 415  U.S.      917, 94 S.Ct. 1413, 39 L.Ed.2d 471 (1974).  Thus, if a      prosecutor plans and executes a raid on a suspected weapons      cache, he "has no greater claim to complete immunity than      activities of police officers allegedly acting under his      direction.' 484 F.2d, at 608-609.'' Id., at 273-274, 113      S.Ct., at 2616.


17
These cases make it clear that the absolute immunity that protects the prosecutor's role as an advocate is not grounded in any special "esteem for those who perform these functions, and certainly not from a desire to shield abuses of office, but because any lesser degree of immunity could impair the judicial process itself.'' Malley, 475 U.S., at 342, 106 S.Ct., at 1097. Thus, in determining immunity, we examine "the nature of the function performed, not the identity of the actor who performed it.'' Forrester v. White, 484 U.S. 219, 229, 108 S.Ct. 538, 545, 98 L.Ed.2d 555 (1988).13 This point is perhaps best illustrated by the determination that the senior law enforcement official in the Nation-the Attorney General of the United States-is protected only by qualified rather than absolute immunity when engaged in the performance of national defense functions rather than prosecutorial functions. Mitchell v. Forsyth, 472 U.S. 511, 105 S.Ct. 2806, 86 L.Ed.2d 411 (1985).


18
In Malley we considered, and rejected, two theories on which immunity might have been accorded to a police officer who had caused an unconstitutional arrest by presenting a judge with a complaint and supporting affidavit that failed to establish probable cause.  His first argument, that his function was comparable to that of a complaining witness, actually militated against his claim because such witnesses were subject to suit at common law.14


19
His second argument rested on the similarity between his conduct and the functions often performed by prosecutors.  As we explained:


20
"As an alternative ground for claiming absolute immunity,      petitioner draws an analogy between an officer requesting a      warrant and a prosecutor who asks a grand jury to indict a      suspect.  Like the prosecutor, petitioner argues, the officer      must exercise a discretionary judgment based on the  evidence      before him, and like the prosecutor, the officer may not      exercise his best judgment if the threat of retaliatory      lawsuits hangs over him.  Thus, petitioner urges us to read      §1983 as giving the officer the same absolute immunity      enjoyed by the prosecutor.  Cf. Imbler v. Pachtman, 424 U.S.      409, 96 S.Ct. 984, 47 L.Ed.2d 128 (1976).


21
.....


22
" . . .  We intend no disrespect to the officer applying for      a warrant by observing that his action, while a vital part of      the administration of criminal justice, is further removed      from the judicial phase of criminal proceedings than the act      of a prosecutor in seeking an indictment.  Furthermore,      petitioner's analogy, while it has some force,  does not take      account of the fact that the prosecutor's act  in seeking an      indictment is but the first step in the process of seeking a      conviction.  Exposing the prosecutor to liability for the      initial phase of his prosecutorial work could interfere with      his exercise of independent judgment at every phase of his      work, since the prosecutor might come to  see later decisions      in terms of their effect on his potential liability.  Thus,      we shield the prosecutor seeking an indictment because any      lesser immunity could impair the performance of a central      actor in the judicial process.''      475 U.S., at 341-343, 106 S.Ct., at 1097.


23
These cases make it quite clear that petitioner's activities in connection with the preparation and filing of two of the three charging documents-the information and the motion for an arrest warrant-are protected by absolute immunity.  Indeed, except for her act in personally attesting to the truth of the averments in the certification, it seems equally clear that the preparation and filing of the third document in the package was part of the advocate's function as well.  The critical question, however, is whether she was acting as a complaining witness rather than a lawyer when she executed the certification " [u]nder penalty of perjury.''  We now turn to that question.

IV

24
The Fourth Amendment requires that arrest warrants be based "upon probable cause, supported by Oath or affirmation''-a requirement that may be satisfied by an indictment returned by a grand jury, but not by the mere filing of criminal charges in an unsworn information signed by the prosecutor. Gerstein v. Pugh, 420 U.S. 103, 117, 95 S.Ct. 854, 864-865, 43 L.Ed.2d 54 (1975); see also Coolidge v. New Hampshire, 403 U.S. 443, 91 S.Ct. 2022, 29 L.Ed.2d 564 (1971).  Accordingly, since most prosecutions in Washington are commenced by information, Washington law requires, in compliance with the constitutional command, that an arrest warrant be supported by either an affidavit "or sworn testimony establishing the grounds for issuing the warrant.''15 The "Certification for Determination of Probable Cause'' executed by petitioner was designed to satisfy those requirements.


25
Although the law required that document to be sworn or certified under penalty of perjury, neither federal nor state law made it necessary for the prosecutor to make that certification. In doing so, petitioner performed an act that any competent witness might have performed.  Even if she may have been following a practice that was routinely employed by her colleagues and predecessors in King County, Washington, that practice is surely not prevalent in other parts of the country and is not even mandated by law in King County.  Neither petitioner nor amici argue that prosecutors routinely follow the  King County practice.16 Indeed, tradition, as well as the ethics  of our profession, generally instruct counsel to avoid the risks  associated with participating as both advocate and witness in the same proceeding.17


26
Nevertheless, petitioner argues that the execution of the certificate was just one incident in a presentation that, viewed as a whole, was the work of an advocate and was integral to the initiation of the prosecution.  That characterization is appropriate for her drafting of the certification, her determination that the evidence was sufficiently strong to justify a probable-cause finding, her decision to file charges, and her presentation of the information and the motion to the court.  Each of those matters involved the exercise of professional judgment; indeed, even the selection of the particular facts to include in the certification to provide the evidentiary support for the finding of probable cause required the exercise of the judgment of the advocate.  But that judgment could not affect the truth or falsity of the factual statements themselves.  Testifying about facts is the function of the witness, not of the lawyer.  No matter how brief or succinct it may be, the evidentiary component of an application for an arrest warrant is a distinct and essential predicate for a finding of probable cause.  Even when the person who makes the constitutionally required "Oath or affirmation'' is a lawyer, the only function that she performs in giving sworn testimony is that of a witness.


27
Finally, petitioner argues that denying her absolute immunity will have a "chilling effect'' on prosecutors in the administration of justice.18 We are not persuaded.


28
It may well be true that prosecutors in King County may abandon the practice of routinely attesting to the facts recited in a "Certification for Determination of Probable Cause'' and pattern their procedures after those employed in other parts of the Nation.  Petitioner presents no evidence that the administration of justice is harmed where the King County practice is not followed.  In other respects, however, her argument addresses concerns that are not affected by our decision because we merely hold that §1983 may provide a remedy for respondent insofar as petitioner performed the function of a complaining witness.  We do not depart from our prior cases that  have recognized that the prosecutor is fully protected by absolute immunity when performing the traditional functions of an advocate. See Imbler, 424 U.S., at 431, 96 S.Ct., at 995-996; Buckley, 509 U.S., at 273, 113 S.Ct., at 2615-2616.


29
Accordingly, the judgment of the Court of Appeals for the Ninth Circuit is


30

Affirmed.



31
Justice SCALIA, with whom Justice THOMAS joins, concurring.


32
I agree that Ms. Kalina performed essentially the same "function'' in the criminal process as the police officers in Malley v. Briggs, 475 U.S. 335, 106 S.Ct. 1092, 89 L.Ed.2d 271 (1986), and so I join the opinion of the Court.  I write separately because it would be a shame if our opinions did not reflect the awareness that our "functional'' approach to 42 U.S.C. §1983 immunity questions has produced some curious inversions of the common law as it existed in 1871, when §1983 was enacted.  A conscientious prosecutor reading our cases should now conclude that there is absolute immunity for the decision to  seek an arrest warrant after filing an information, but only qualified immunity for testimony as a witness in support of that  warrant. The common-law rule was, in a sense, exactly opposite.


33
There was, of course, no such thing as absolute prosecutorial immunity when §1983 was enacted. (Indeed, as the Court points out, ante, at __, n. 11, there generally was no such thing as the modern public prosecutor.)  The common law recognized a "judicial'' immunity, which protected judges, jurors and grand jurors, members of courts martial, private arbitrators, and various assessors and commissioners.  That immunity was absolute, but it extended only to individuals who were charged with resolving disputes between other parties or authoritatively adjudicating private rights.  When public officials made discretionary policy decisions that did not involve actual adjudication, they were protected by "quasi-judicial'' immunity, which could be defeated by a showing of malice, and hence was more akin to what we now call "qualified,'' rather than absolute, immunity.  I continue to believe that "prosecutorial functions, had they existed in their modern form in 1871, would have been considered quasi-judicial.'' Burns v. Reed, 500 U.S. 478, 500, 111 S.Ct. 1934, 1947, 114 L.Ed.2d 547 (1991) (SCALIA, J., concurring in judgment in part and dissenting in part).


34
That conclusion accords with the common law's treatment of private prosecutors, who once commonly performed the "function'' now delegated to public officials like petitioner.  A private citizen who initiated or procured a criminal prosecution could (and can still) be sued for the tort of malicious prosecution-but only if he acted maliciously and without probable cause, and the prosecution ultimately terminated in the defendant's favor.  Thus, although these private prosecutors (sometimes called "complaining witnesses''), since they were not public servants, were not entitled to quasi-judicial immunity, there was a kind of qualified immunity built into the elements of the tort.


35
The common law also recognized an absolute immunity for statements made in the course of a judicial proceeding and relevant to the matter being tried.  That immunity protected both witnesses and attorneys, and could not be defeated even by an allegation that the statement was maliciously false.  See, e.g., F. Hilliard, Law of Torts 319 (1866).  It was, however, an immunity only against slander and libel actions.


36
At common law, therefore, Kalina would have been protected by something resembling qualified immunity if she were sued for malicious prosecution.  The tortious act in such a case would have been her decision to bring criminal charges against Fletcher, and liability would attach only if Fletcher could prove that the prosecution was malicious, without probable cause, and ultimately unsuccessful.  Kalina's false statements as a witness  in support of the warrant application would not have been an independent actionable tort (although they might have been evidence of malice or initiation in the malicious prosecution suit), because of the absolute privilege protecting such testimony from suits for defamation.


37
The Court's long road to what is, superficially at least, the opposite result in today's opinion, began with Imbler v. Pachtman, 424 U.S. 409, 96 S.Ct. 984, 47 L.Ed.2d 128 (1976), which granted prosecutors absolute immunity for the "function'' of initiating a criminal prosecution.  Then, in Briscoe v. LaHue, 460 U.S. 325, 103 S.Ct. 1108, 75 L.Ed.2d 96 (1983), the Court extended a similar absolute immunity to the "function'' of serving as a witness.  And in Malley v. Briggs, supra, it recognized the additional "functional category'' of "complaining  witness.''  Since this category was entitled to only qualified immunity, the Court overturned a directed verdict in favor of a police officer who had caused the plaintiff to be arrested by presenting a judge with a complaint and an affidavit supporting probable cause.  The Court said:


38
" [C]omplaining witnesses were not absolutely immune at      common law.  In 1871, the generally accepted rule was that      one who procured the issuance of an arrest warrant by      submitting a complaint could be held liable if the complaint      was made maliciously and without probable cause.  Given      malice and the lack of probable cause, the complainant      enjoyed no immunity.'' Id., at 340-341, 106 S.Ct., at      1095-1096.


39
That statement is correct, but it implies a distinction between "witnesses'' (absolutely immune) and "complaining witnesses'' (at best qualifiedly immune) which has little foundation in the common law of 1871.  That law did not recognize two kinds of witness; it recognized two different torts. "In this sense, then, Malley's discussion of complaining witnesses is a feint.  The Court was not awaking to a different type of witness  . . .  so much as recognizing a different cause of action-the action for malicious prosecution.''  Comment, Police Witness Immunity Under  §1983, 56 U. Chi. L.Rev. 1433, 1454 (1989).  By the time Malley was decided, however, the Court's methodology forced it to express its conclusion in terms of whether the particular "function'' at issue would have been entitled to immunity at common law.  See, e.g., Briscoe, supra, at 342, 103 S.Ct., at 1119 ("our cases clearly indicate that immunity analysis rests on functional categories'').  By inventing "a new functional category: the complaining witness, who (in the Court's specially-tailored history) was liable at common law and so is liable under §1983,'' Comment, supra, at __, Malley moved the Court's immunity jurisprudence much closer to the results the common law would have achieved.


40
But no analytical approach based upon "functional analysis'' can faithfully replicate the common law, as is demonstrated in the Court's opinion today.  By describing the subset of actors in the criminal process who are subject to suit as "complaining witnesses, '' the Court implies that testifying is the critical event.  But a "complaining witness'' could be sued for malicious prosecution whether or not he ever provided factual testimony, so long as he had a role in initiating or procuring the prosecution; in that sense, the "witness'' in "complaining witness'' is misleading.  As applied to the police officers in Malley, that confusion was more or less harmless.  Here, however, Imbler and Malley collide to produce a rule that stands the common law on its head: Kalina is absolutely immune from any suit challenging her decision to prosecute or seek an arrest warrant, but can be sued if she changes "functional categories'' by providing personal testimony to the Court.

Imbler's principle of absolute prosecutorial immunity, and the "functional categories'' approach to immunity questions imposed by cases like Briscoe, make faithful adherence to the common law embodied in §1983 very difficult.  But both Imbler and the "functional'' approach are so deeply embedded in our §1983 jurisprudence that, for reasons of stare decisis, I would not abandon them now.  Given those concessions, Malley's distortion of the term "complaining witness'' may take us as close to the right answer as we are likely to get.  Because Kalina's conduct clearly places her in that functional category, I agree with the  Court that she is not entitled to absolute immunity under our precedents.

 Title 42 U.S.C. §1983 provides:
"Every person who, under color of any statute, ordinance, regulation, custom, or usage, of any State or Territory or the District of Columbia, subjects, or causes to be subjected, any citizen of the United States or other person within the jurisdiction thereof to the deprivation of any rights, privileges, or immunities secured by the Constitution and laws, shall be liable to the party injured in an action at law, suit in equity, or other proper proceeding for redress  . . .  .''


11
 See 424 U.S., at 421-422, 96 S.Ct., at 990-991.  The cases that the Court cited were decided after 1871 and granted a broader immunity to public prosecutors than had been available in malicious prosecution actions against private persons who brought prosecutions at early common law.  See Savile v. Roberts, 1 Ld. Raym. 374, 91 Eng. Rep. 1147 (K.B.1699); Hill v. Miles, 9 N.H. 9 (1837); M. Bigelow, Leading Cases on the Law of Torts 193-204 (1875).  However, these early cases were decided before the office of public prosecutor in its modern form was common.  See Langbein, The Origins of Public Prosecution at Common Law, 17 Am. J. Legal Hist. 313, 316 (1973); Kress, Progress and Prosecution, 423 Annals Am. Acad. Pol. & Soc. Sci. 99, 100-102 (1976); White v. Frank, 855 F.2d 956, 962 (C.A.2 1988) (noting that "the availability of the malicious prosecution action has been curtailed with the growth of the office of the public prosecutor'').  Thus, the Court in Imbler drew guidance both from the first American cases addressing the availability of malicious prosecution actions against public prosecutors, and perhaps more  importantly, from the policy considerations underlying the firmly established common-law rules providing absolute immunity for judges and jurors.  See Imbler v. Pachtman, 424 U.S., at 423, n. 20, 96 S.Ct., at 991 n. 20 (discussing similarity in some functions performed by judges, jurors, and prosecutors); Bradley v. Fisher, 13 Wall. 335, 347, 20 L.Ed. 646 (1871); Yates v. Lansing, 5 Johns. 282 (N.Y.1810) (Kent, C. J.); Note, Civil Liability of a District Attorney for Quasi-Judicial Acts, 73 U. Pa. L.Rev. 300, 303, n. 13 (1925).


12
 See 424 U.S., at 439-440, 96 S.Ct., at 999-1000 (White, J., concurring in judgment).


13
 Examining the nature of the function performed is not a recent innovation.  In Ex parte Virginia, 100 U.S. 339, 348, 25 L.Ed. 676 (1879), we stated " [w]hether the act done by [a judge] was judicial or not is to be determined by its character, and not by the character of the agent.''  See also Bradley v. Fisher, 13 Wall., at 347, 20 L.Ed. 646 (examining "the character of the act'' performed by a judge).


14
 We noted that:
" [C]omplaining witnesses were not absolutely immune at common law.  In 1871, the generally accepted rule was that one who procured the issuance of an arrest warrant by submitting a complaint could be held liable if the complaint was made maliciously and without probable cause.  Given malice and the lack of probable cause, the complainant enjoyed no immunity.  The common law thus affords no support for petitioner.'' Malley v. Briggs, 475 U.S. 335, 340-341, 106 S.Ct. 1092, 1096, 89 L.Ed.2d 271 (1986) (footnote omitted).


15
 Washington Criminal Rule 2.2(a) provides:
"A warrant of arrest must be supported by an affidavit,  . . .  or sworn testimony establishing the grounds for issuing the warrant  . . . . The court must determine there is probable cause . . .  before issuing the warrant.''


16
 Amicus Curiae United States points out that federal prosecutors typically do not personally attest to the facts in an affidavit filed in support of an application for an arrest warrant, but " [i]nstead a law enforcement agent ordinarily attests to those facts.''  Brief for United States 7. Amici Curiae Thirty-Nine Counties of the State of Washington state that local court rules in only two counties in Washington require the prosecutor to file an additional document beyond an information.
