DAVID T. PROSSER, J.
¶ 1. The issue presented in this case is whether the good-faith exception to the exclusionary rule permits the use of evidence obtained by a law enforcement officer in his execution of an arrest warrant that was void from the beginning because the warrant had no basis in fact or law. The State contends that suppression of evidence from a warrant issued solely as a result of judicial error would not further the purposes of the exclusionary rule.
¶ 2. We conclude that the good-faith exception to the exclusionary rule does not apply to a situation in which: (1) no facts existed that would justify an arrest without a warrant; (2) the civil arrest warrant issued by a circuit judge was void ah initio1 because (a) it did not comply with any statute authorizing the court to issue a warrant; and (b) it was not supported by an oath or affirmation; and (3) the court issued the warrant without the benefit of verification of the facts or scrutiny of the procedure to ensure that the judge acted as a detached and neutral magistrate.
¶ 3. The warrant here was defective on its face. Nonetheless, we cannot reasonably attribute fault to the law enforcement officer who executed the warrant. Thus, suppressing evidence obtained as a result of the unauthorized, defective warrant is necessary to pre[530]*530serve the integrity of the judicial process. Consequently, we affirm the decision of the court of appeals, State v. Hess, 2009 WI App 105, 320 Wis. 2d 600, 770 N.W.2d 769.
I. BACKGROUND AND PROCEDURAL HISTORY
¶ 4. In mid-2005 the defendant, Michael R. Hess, was arrested in Walworth County for operating a motor vehicle under the influence of an intoxicant, in violation of Wis. Stat. § 346.63(1)(a) (2007-08).2 Hess was released on a $1,000 cash bond, which included various conditions including requirements that he "appear on all court dates" and "not possess or consume alcohol."
¶ 5. Hess subsequently pled guilty to the offense — a felony — and on January 12, 2007, the court ordered a presentence investigation (PSI). The order stated: "The Department of Corrections (Department) shall conduct a presentence investigation and prepare a report based on this investigation." It also set March 28, 2007, as the sentencing date. The court adjusted Hess's bond to a $10,000 signature bond with conditions of release similar to those in the original bond.
¶ 6. On February 8, 2007, the PSI author, a Department of Corrections agent, sent a letter to the circuit court. The letter explained that the agent had contacted Hess to schedule a meeting for February 1. Hess appeared at the meeting. The agent then reviewed a questionnaire that she had sent to Hess, noticing that portions of it were incomplete. When asked why he had not completed the questionnaire, Hess responded that it incorrectly listed the offense as his fifth OWL The agent then asked Hess to return to the lobby to com[531]*531píete the questionnaire, after which the interview would begin. Hess then left, which the agent presumed was because Hess was feeling ill.
¶ 7. The agent was unable to contact Hess after this meeting. She left a message with Hess's mother asking Hess to contact the agent by 4 p.m. that day. Hess did not respond, although he left a message with the agent's supervisor complaining about the agent. The agent's supervisor contacted Hess and directed him to return to complete the interview on February 6. He did not comply. The agent also was unable to contact Hess's attorney. Thus, the agent concluded her letter to the court with the following paragraph:
It should be noted that to date, Mr. Hess has not attempted to contact this agent or [the agent's supervisor]. Therefore, due to the current situation and Mr. Hess' failure to cooperate, as outlined above, this agent does not foresee, at this time, that the Pre-Sentence Investigation ordered by the Court will be completed as requested. However, it is respectfully requested that Mr. Hess be placed in custody, which would allow the Pre-Sentence Investigation to be completed. Should the Court concur with this request, please notify our office of such.
(Emphasis added.)
¶ 8. On February 14, 2007, Circuit Judge John Race issued a "Bench Warrant Civil." This warrant directed "any law enforcement officer" to "[a]rrest and deliver to the sheriff the above named person because this person:. .. failed to: Meet with the Agent assigned to complete his Pre-Sentence Investigation." The warrant specified that Hess could be released upon "Completion of the Presentence Investigation Interview with the Agent assigned."
[532]*532¶ 9. On March 7, 2007, Deputy Gilbert Maas of the Walworth County Sheriffs Department went to Hess's address, understanding that he "had a criminal felony arrest warrant for Michael Hess." When he arrived, Deputy Maas encountered Hess's father at the front door. After a brief conversation with Hess's father, Deputy Maas spoke with Hess himself and advised him that he had an arrest warrant for failure to appear in court. As the two men were walking to the squad car, Deputy Maas smelled the odor of intoxicants coming from Hess. He placed Hess under arrest, handcuffed him, did a pat-down search, and placed Hess in the back of the squad car.
¶ 10. Following normal procedure, Deputy Maas requested the dispatch center to check if Hess was on any conditions of bond. He was advised by the dispatch center that Hess was on bond for a sixth offense drunk driving with a minor in the vehicle and that one of the conditions of his bond was that he not possess or consume alcohol. Deputy Maas then transported Hess to Lakeland Medical Center to obtain a blood draw.
¶ 11. Hess was thereafter charged with felony bail jumping, in violation of Wis. Stat. § 946.49, for violating the bond requirement that he not possess or consume alcohol. He in turn filed a motion to suppress any evidence obtained as a result of the civil warrant. This included Deputy Maas's observations regarding Hess's sobriety on March 7. Hess argued that the civil bench warrant was invalid because it failed to conform to the requirements for a civil bench warrant in Wis. Stat. ch. 818. Specifically, he argued that (1) none of the enumerated situations in which an arrest may be made was present; and (2) the court was not furnished with an affidavit prior to issuing the warrant. He argued that [533]*533all evidence obtained on March 7 must be suppressed as the fruit of an illegal arrest.
¶ 12. The circuit court, Judge James Carlson presiding, held a hearing on the motion to suppress. The court declined to take testimony at the hearing because it deemed the legality of the warrant an issue of law. It then denied the motion, reasoning that the warrant was valid under either (1) the court's inherent power to issue warrants; or (2) the court's general statutory powers under Wis. Stat. § 757.01. The circuit court also stated that even if the warrant were not valid, the evidence was admissible under the good-faith exception to the exclusionary rule.
¶ 13. The case proceeded to a jury trial, at which Deputy Mass testified regarding his observations on March 7. The jury found Hess guilty. The court withheld sentence and placed Hess on three years probation. Hess appealed.
¶ 14. The court of appeals reversed and remanded after suppressing the evidence. Hess, 320 Wis. 2d 600, ¶ 3. The court analyzed the validity of the warrant, observing that the circuit court lacked the authority to issue a civil bench warrant because this was a criminal case. Id., ¶ 11 (citing Wis. Stat. ch. 818). The court then noted that the court lacked the authority to issue a criminal bench warrant under Wis. Stat. § 968.09(1) because Hess did not fail to appear in court and was under no express or implied requirement to meet with the PSI writer. Id., ¶ 12. Finally, the court said that the court had no authority to issue a warrant for contempt because the court did not order Hess to cooperate with the PSI writer. Id., ¶ 13. The court concluded that, because warrants may be issued only pursuant to statute, the arrest warrant was invalid. Id., ¶ 14 (citing Wagner v. Lathers, 26 Wis. 436, 438 (1870)).
[534]*534¶ 15. The court next examined the applicability of the exclusionary rule. The court noted that the primary purpose of the rule was to deter unlawful police conduct while also preserving judicial integrity. Hess, 320 Wis. 2d 600, ¶ 16 (citing Terry v. Ohio, 392 U.S. 1, 12-13 (1968)). It cited State v. Kriegbaum, 194 Wis. 229, 232, 215 N.W. 896 (1927), for the proposition that the exclusionary rule prohibits evidence obtained pursuant to a warrant issued by a judge with no legal authority to issue such a warrant. Hess, 320 Wis. 2d 600, ¶¶ 17-18.
¶ 16. The court of appeals next turned to the good-faith exception to the exclusionary rule. It reasoned that the good-faith exception, as set out in United States v. Leon, 468 U.S. 897 (1984), and State v. Eason, 2001 WI 98, 245 Wis. 2d 206, 629 N.W.2d 625, "allow[s] the admission of evidence when law enforcement officers did what they were supposed to .. . but someone made an accidental clerical or technical error or the judge erred in concluding that the law enforcement's application fulfilled the requirements for a warrant." Hess, 320 Wis. 2d 600, ¶ 21. The court rejected the State's argument that the good-faith exception applies where the error is judicial, reasoning that the court in this case did not merely make an error, but acted outside the law. Id., ¶ 22.
¶ 17. The court declared that the purpose of the good-faith exception is not simply to deter police misconduct, id., ¶ 23, but also to preserve judicial integrity, meaning that courts must ensure "that our judicial process does not sanction, approve and be party to constitutional violations," id., ¶ 25. Finally, the court examined cases in several different jurisdictions to conclude that "the good faith exception does not apply when a judge acts outside the law by issuing a warrant he or she had no authority whatsoever to issue." Id., [535]*535¶ 26; United States v. Scott, 260 F.3d 512, 515 (6th Cir. 2001); Bosteder v. City of Renton, 117 P.3d 316, 323 (Wash. 2005); State v. Wilson, 618 N.W.2d 513, 520 (S.D. 2000).
¶ 18. The State petitioned this court for review, which we granted.
II. STANDARD OF REVIEW
¶ 19. We review a motion to suppress in two steps. State v. Matejka, 2001 WI 5, ¶ 16, 241 Wis. 2d 52, 621 N.W.2d 891. First, we uphold the circuit court's findings of historical fact unless they are clearly erroneous. Id. Second, we independently apply constitutional principles to those facts. Id. The constitutional sufficiency of a warrant and the application of the good-faith exception to the exclusionary rule are issues of law, which we review de novo. See State v. Meyer, 216 Wis. 2d 729, 744, 576 N.W.2d 260 (1998); Eason, 245 Wis. 2d 206, ¶ 9.
III. DISCUSSION
¶ 20. The State concedes that the arrest warrant was invalid. As a result, the State's evidence of Hess's consumption and possession of alcohol — the evidence used to convict Hess of felony bail jumping — was obtained in violation of the Fourth Amendment to the United States Constitution and Article I, § 11 of the Wisconsin Constitution. Thus, the issue in this case is whether exclusion of that evidence is appropriate, or whether the court should permit use of the evidence on grounds that law enforcement obtained the evidence while acting in good-faith reliance on an arrest warrant that was void.
[536]*536¶ 21. In resolving this issue, we begin by examining the statutory and constitutional warrant requirements and the deficiencies of the warrant at issue in this case. We then consider the historical development of the exclusionary rule and its good-faith exception in the federal courts as well as the parallel developments in Wisconsin. Finally, we apply these principles to determine whether exclusion is an appropriate remedy under the unusual facts of this case.
A. Warrant Requirements in Wisconsin
¶ 22. The warrant in this case suffered from two primary defects: (1) the circuit court did not have statutory authority to issue a warrant for failure to meet with a PSI investigator; and (2) the warrant was not supported by an oath or affirmation.
1. Lack of Statutory Authority
¶ 23. The defendant contends and the State concedes that the arrest warrant was issued without authority.
¶ 24. Under appropriate circumstances, a circuit court has statutory authority to issue a (1) civil bench warrant, (2) a criminal bench warrant, or (3) a contempt warrant. To illustrate, had the circuit court ordered Hess to comply with the requests of the PSI writer or made his cooperation a condition of bond, the court might have ordered the defendant arrested for contempt (Wis. Stat. §§ 785.03(1)(b), 785.04(1)) or issued a criminal bench warrant (Wis. Stat. § 968.09(1)) after Hess failed to follow up with the PSI writer. Had Hess failed to appear before the court on a civil matter, a civil bench warrant would have been appropriate [537]*537(Chapter 818). Under the facts of this case, however, the warrant cannot be supported by any of these various statutes. The court issued what purported to be a civil bench warrant in a criminal case on the basis of Hess's failure to comply with an order the court never gave.
¶ 25. Civil arrests are governed by Wis. Stat. ch. 818. In a civil action, arrests are to be made only "as prescribed by this chapter." Wis. Stat. § 818.01(1). The statute then lists eight circumstances under which a defendant may be arrested pursuant to a civil bench warrant. Wis. Stat. § 818.02. The procedures under the chapter, in turn, require that an "order for the arrest of the defendant must be obtained from the court." Wis. Stat. § 818.03. The court may issue such an order "where it shall appear by affidavit that a cause of action exists, and that it is one of those mentioned in s. 818.02." Wis. Stat. § 818.04 (emphasis added). To execute the warrant, "ft]he affidavit, bond and order of arrest shall be delivered to the sheriff." Wis. Stat. § 818.07 (emphasis added).
¶ 26. Nothing in the record suggests that any of the circumstances authorizing a civil bench warrant under § 818.02 existed. No affidavit was provided to the circuit court demonstrating the existence of any of those circumstances, and consequently no affidavit accompanied the order for arrest delivered to the sheriff. Equally important, the matter pending before the court was criminal, not civil. Therefore, the court was without authority to issue a civil bench warrant.
¶ 27. The court may issue a warrant for the arrest of a defendant when a judge determines that there is probable cause to believe that a criminal offense has been committed and that the accused has committed it. [538]*538Wis. Stat. § 968.04. Hess's failure to cooperate with the agent in preparing a PSI was not a crime. In addition, under Wis. Stat. § 968.09(1), a court may issue a criminal arrest warrant when a witness fails to appear before the court as required "or violates a term of the defendant's. .. bond." Here, Hess had not failed to appear for a court date. Nor had he violated a term of his bond, because meeting with the PSI agent was not a condition of his bond. Therefore, the circuit court was without authority to issue an arrest warrant under § 968.09(1).
¶ 28. Finally, Wis. Stat. ch. 785 permits a circuit court to order imprisonment as a remedial sanction for contempt of court. Such contempt is defined in relevant part as intentional "[m]isconduct in the presence of the court" or "[d]isobedience, resistance or obstruction of the authority, process or order of a court." Wis. Stat. § 785.01(1)(a)-(b). There is nothing in the record to suggest that Hess satisfied either definition of contempt of court. In particular, he did not fail to comply with an explicit order of the court. Therefore, the arrest warrant was not authorized under ch. 785.
¶ 29. Because the circuit court had no authority to issue the warrant it did, exclusion is an appropriate remedy for evidence obtained as a result of that warrant. This court held in Kriegbaum that where a magistrate lacked authority to issue a warrant, the search conducted and evidence seized resulted in a constitutional violation. Kriegbaum, 194 Wis. at 232. In Kriegbaum, a justice of the peace issued a warrant authorizing a search of the person of the defendant, but the statutes authorized justices of the peace to issue warrants only to search a "particular house or place." Id. From these facts, the court held: "A search made [539]*539pursuant to warrant issued by a justice of the peace to whom the legislature had not granted the power to issue such a warrant is an unreasonable search and in violation of the defendant's constitutional rights." Id.
¶ 30. The court of appeals has applied the principle articulated in Kriegbaum in several cases. In these cases, the court held that evidence must be suppressed when it was obtained pursuant to a warrant issued by a court commissioner not authorized to issue search warrants. State v. Loney, 110 Wis. 2d 256, 258-60, 328 N.W.2d 872 (Ct. App. 1982); State v. Grawien, 123 Wis. 2d 428, 431, 367 N.W.2d 816 (Ct. App. 1985).3 These cases, together with Kriegbaum, support the conclusion that exclusion is an appropriate remedy where evidence was obtained by a warrant issued by a magistrate who lacked the authority to issue the warrant.
¶ 31. This basic principle is reinforced by State v. Popenhagen, 2008 WI 55, 309 Wis. 2d 601, 749 N.W.2d 611. In Popenhagen, the state obtained evidence pursuant to subpoenas that did not satisfy the statutory requirement of a showing of probable cause. Id., ¶¶ 7, [540]*54013. We held that suppression was necessary because the means by which the state procured evidence was in violation of the procedures set out by statute. Id., ¶ 97. Allowing documents obtained by a subpoena not complying with the statutory probable cause requirement would make the statutory safeguards meaningless. Id., ¶ 61. By the same token, we held that suppression of an incriminating statement procured by use of those same documents was necessary to fully protect persons from the state's failure to comply with the statute. Id., ¶ 85. Like the subpoenas in Popenhagen, the warrant in this case did not conform to the basic statutory requirements.4
¶ 32. These cases lead us to conclude that because the statutes did not authorize a warrant under these circumstances, the warrant was void ab initio. In such a situation, exclusion is an appropriate remedy. The State is no more entitled to the use of the evidence here than it would be had law enforcement placed Hess in custody without a warrant in circumstances where a warrant was required. The warrant had no basis in fact or law and was void from the moment it was issued; therefore, the evidence seized pursuant to Hess's arrest is subject to the exclusionary rule.
2. Lack of Oath or Affirmation
¶ 33. Both the United States and Wisconsin Constitutions provide that "no Warrants shall issue, but [541]*541upon probable cause, supported by Oath or affirmation . . . U.S. Const. amend. IV; Wis. Const. art. 1, §11. We have declined to consider this requirement a mere technicality, but have upheld its basic substantive importance, stating:
An oath is a matter of substance, not form, and it is an essential component of the Fourth Amendment and legal proceedings. The purpose of an oath or affirmation is to impress upon the swearing individual an appropriate sense of obligation to tell the truth. An oath or affirmation to support a search warrant reminds both the investigator seeking the search warrant and the magistrate issuing it of the importance and solemnity of the process involved. An oath or affirmation protects the target of the search from impermissible state action by creating liability for perjury or false swearing for those who abuse the warrant process by giving false or fraudulent information. An oath preserves the integrity of the search warrant process and thus protects the constitutionally guaranteed fundamental right of people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures.
State v. Tye, 2001 WI 124, ¶ 19, 248 Wis. 2d 530, 636 N.W.2d 473 (footnotes omitted).
¶ 34. When a warrant fails to comply with the constitutional oath or affirmation requirement, we have considered it to be "invalid when issued." Id., ¶ 23. In Tye the warrant was "facially defective because no sworn affidavit was attached," although the court held and the parties stipulated that the affidavit, if true and sworn, would have provided probable cause for the search. Id., ¶¶ 5, 7. We contrasted the warrant's deficiency with a case where the error was in the street number of the premises to be searched. State v. Nicholson, 174 Wis. 2d 542, 544, 497 N.W.2d 791 (Ct. App. 1993). In Nicholson, [542]*542however, this error was only a "technical irregularity not affecting the substantial rights of the defendant," allowing the warrant itself to be valid when issued. Tye, 248 Wis. 2d 530, ¶ 23.
¶ 35. Here, the arrest warrant was not accompanied by an affidavit, sworn or unsworn. The absence of an affidavit violated Wis. Stat. §§ 818.04 and 818.07. The absence of a sworn affidavit violated the state and federal constitutions and rendered evidence obtained as a result of the warrant inadmissible. Tye, 248 Wis. 2d 530, ¶ 3. An oath or affirmation is necessary "to induce an honest belief in the mind of the magistrate" that probable cause exists. Kraus v. State, 226 Wis. 383, 386 (1937) (citing State v. Baltes, 183 Wis. 545, 552, 198 N.W. 282 (1924) (suppressing evidence because no sworn testimony existed to support the warrant)).
¶ 36. The oath or affirmation and probable cause requirements apply equally to arrest warrants as well as search warrants. Giordenello v. U.S., 357 U.S. 480, 485-86 (1958). The sworn complaint or affidavit is necessary to allow the judge or magistrate to make an informed determination regarding the existence of probable cause. Id. at 486. The test for the sufficiency of a sworn complaint or affidavit is whether it can "support the independent judgment of a disinterested magistrate." Whiteley v. Warden, Wyo. State Pen., 401 U.S. 560, 565 (1971).
¶ 37. Without an affidavit accompanied by oath or affirmation, the warrant failed to meet a basic constitutional requirement and was void ab initio. See Tye, 248 Wis. 2d 530, ¶ 13. The absence of any affidavit should have put both the court and the sheriffs department on notice of a problem.
[543]*543B. The Exclusionary Rule and Good-Faith Exception
¶ 38. Although we hold that the exclusionary rule applies because the warrant was void when issued, the State asks us to extend the good-faith exception to the exclusionary rule in Wisconsin to render evidence admissible when it is seized pursuant to a warrant issued without statutory authority. To determine whether such an extension of the good-faith exception is appropriate, we begin by examining the historical background of the exclusionary rule in the federal courts and in Wisconsin. We then apply these principles to the situation in which a circuit court issues a warrant without statutory authority and unsupported by an oath or affirmation.
1. The Federal Exclusionary Rule
¶ 39. The origin of the Fourth Amendment exclusionary rule can be traced to the Supreme Court's decision in Weeks v. United States, in which the Court considered a defendant's timely objection to the warrantless seizure of evidence from his residence. Weeks v. United States, 232 U.S. 383, 387-88 (1914). The import of the Fourth Amendment, it explained, was "to put the courts... under limitations and restraints as to the exercise of [their] power and authority." Id. at 391-92. It concluded that unlawful seizures "should find no sanction in the judgments of the courts which are charged at all times with the support of the Constitution." Id. at 392. Accordingly, the Court held that the trial court erred by refusing the return of the papers and by allowing them to be used at trial. Id. at 398.
¶ 40. Initially, the exclusionary rule created in Weeks applied only to federal officers and federal courts. In Wolf v. Colorado, the Court acknowledged that the [544]*544Fourth Amendment protections are applied to the states through the Due Process Clause of the Fourteenth Amendment, but it declined to extend the exclusionary rule to the states on grounds that the rule was not required by the text of the Constitution or by virtue of legislation. Wolf v. Colorado, 338 U.S. 25, 27-28 (1949). Rather, exclusion was "a matter of judicial implication." Id. at 28. Instead of imposing the exclusionary rule on the states' administration of justice, the Court chose to allow the states to pursue other methods that might be equally effective solutions to the constitutional problem. Id. at 31.
¶ 41. Twelve years later, however, the Court reconsidered this view and overruled Wolf, holding that "all evidence obtained by searches and seizures in violation of the Constitution is . . . inadmissible in a state court." Mapp v. Ohio, 367 U.S. 643, 655 (1961). To hold, as Wolf did, that the Fourth Amendment as applied to the states does not impose consequences for violations would be "to grant the right but in reality to withhold its privilege and enjoyment." Id. at 656. In response to criticism that the exclusionary rule results in letting the guilty go free, the Court reaffirmed an earlier holding from Elkins v. United States:
"[T]here is another consideration — the imperative of judicial integrity." The criminal goes free, if he must, but it is the law that sets him free. Nothing can destroy a government more quickly than its failure to observe its own laws, or worse, its disregard of the charter of its own existence.
Mapp, 367 U.S. at 659 (quoting Elkins v. United States, 364 U.S. 206, 222 (1960)) (internal citations omitted). The Court went on to emphasize that applying the exclusionary rule to the states "is not only the logical dictate of prior cases, but it also makes very good sense. [545]*545There is no war between the Constitution and common sense." Mapp, 367 U.S. at 657.
¶ 42. The Court elaborated on the purposes and functions of the exclusionary rule in the context of police officer "stop and frisk" seizures in Terry v. Ohio. In Terry the Court held that excluding evidence seized in violation of the Fourth Amendment seeks to deter unlawful police conduct while serving another "vital function — 'the imperative of judicial integrity.'" Terry, 392 U.S. at 12-13 (citing Elkins, 364 U.S. at 222). The Court ultimately concluded that the police officer's actions in Terry were proper under the Fourth Amendment, but emphasized that "[cjourts which sit under our Constitution cannot and will not be made party to lawless invasions of the constitutional rights of citizens." Terry, 392 U.S. at 13.
¶ 43. Sixteen years later, the Supreme Court modified the exclusionary rule to provide a good-faith exception when a police officer relies in good faith on a facially valid warrant that was issued by a neutral and detached magistrate. Leon, 468 U.S. at 905. Crucial to the Court's analysis was balancing the interests of preserving probative evidence in criminal trials and removing any incentive for official misconduct or constitutional violations. Id. at 900-01.
¶ 44. The Court tempered the good-faith exception by identifying four circumstances in which the good faith reliance of an officer will not save unconstitutionally obtained evidence: (1) where the facially valid affidavit is based upon knowingly or recklessly made false statements; (2) where the issuing judge or magistrate "wholly abandoned his judicial role;" (3) where the affidavit was insufficient to allow the magistrate to make a determination of probable cause; and (4) where the officer [546]*546cannot demonstrate objective good faith because the affidavit supporting the warrant is "so lacking in indicia of probable cause as to render official belief in its existence entirely unreasonable." Id. at 923.
¶ 45. Since Leon, the Court has continued to reexamine the boundaries of the good-faith exception. In Illinois v. Krull the Court extended the good-faith exception to allow evidence seized pursuant to a state statute later deemed unconstitutional. Illinois v. Krull, 480 U.S. 340, 349 (1987) (relying on Leon, 468 U.S. at 920-21, for the proposition that the deterrence function of the rule would not be furthered where the police officer's reliance was objectively reasonable). The Court later declined to apply the exclusionary rule to clerical errors by court employees where law enforcement's behavior was reasonable. Arizona v. Evans, 514 U.S. 1, 15-16 (1995). Most recently, the Court considered whether a clerical error by police personnel should likewise be exempted from the scope of the exclusionary rule. Herring v. United States, 555 U.S. 135, 129 S. Ct. 695, 703 (2009). Although the Court rejected a categorical exception similar to the one in Evans, it held that the police conduct in Herring did not warrant exclusion because it "was the result of isolated negligence attenuated from the arrest." Id. at 698.
2. The Exclusionary Rule in Wisconsin
¶ 46. In Wisconsin, the exclusionary rule dates back to 1923, when this court held that, for "the Bill of Rights as embodied in constitutions to be of substance rather than mere tinsel," a conviction may not rest on unlawfully seized evidence. Hoyer v. State, 180 Wis. 407, 415, 193 N.W. 89 (1923). Although the court acknowledged that other states had reached contrary conclu[547]*547sions, it found "no reason in logic, justice, or in . . . fair play" why a court of justice should allow the use of evidence obtained through a plain violation of the constitution. Id. at 417. The court instead elected to follow federal precedent, which at that time considered the unlawful seizure of evidence analogous to compelled self-incrimination under the Fifth Amendment. Id. at 415-16. The constitutional guarantee of security against unreasonable search and seizure cannot be discarded in favor of a conviction obtained by the violation of that same guarantee. Id. at 417. "Such a cynical indifference to the state's obligations should not he judicial policy." Id.
¶ 47. In subsequent cases, the court continued to follow the United States Supreme Court in the development and application of the exclusionary rule: Echoing the Supreme Court's language in Elkins, the court identified two rationales underlying the rule: deterrence of unlawful police conduct and assurance of judicial integrity. Conrad v. State, 63 Wis. 2d 616, 635, 218 N.W.2d 252 (1974). In Conrad we recognized that both purposes have their limits in reality: deterrence cannot be achieved where persons are never charged or tried, and the integrity of judicial process may be compromised when relevant evidence is excluded from the truth-finding process. Id. Imperfect though the remedy might be, the court recognized the important principles underlying the rule's development and concluded that "[cjourts and judges should not sanction violations of the constitution." Id.5
[548]*548¶ 48. In State v. Brady the court was asked to reconsider Hoyer in light of the Supreme Court's decision in Leon. State v. Brady, 130 Wis. 2d 443, 453, 388 N.W.2d 151 (1986). Brady challenged the validity of a material witness arrest warrant issued by a judge in a John Doe proceeding, arguably without statutory authority. Id. at 449-50. The court did not address whether the judge had authority to issue the warrant, concluding that even if the judge had authority, the warrant was void because it was lacking in probable cause. Id. at 453. The court declined to adopt the good-faith exception because the circumstances of the case fell within one of the four limiting situations identified in Leon: the warrant was so lacking in indicia of probable cause that the question of "good faith" was not implicated. Id. at 454. Justice Abrahamson noted in a concurrence:
It is not clear whether Leon ... appl[ies] only to cases in which the magistrate has authority to issue a warrant but there was lack of probable cause or a technical error... or to cases such as this one in which the magistrate has no authority whatsoever to issue the warrant.
Id. at 455 (Abrahamson, J., concurring). Accordingly, the court left the good-faith exception for another day.
¶ 49. The first decision of this court to recognize a good-faith exception did so in the limited context in which law enforcement relied on controlling law at the time of the search, although that law was subsequently overruled. State v. Ward, 2000 WI 3, 231 Wis. 2d 723, 604 N.W.2d 517. In Ward, law enforcement had properly relied on a warrant containing no-knock entry authorization, pursuant to the rule articulated by this court in State v. Stevens, 181 Wis. 2d 410, 424-25, 511 N.W.2d [549]*549591 (1994), and State v. Richards, 201 Wis. 2d 845, 549 N.W.2d 218 (1996). Ward, 231 Wis. 2d at 743. The United States Supreme Court issued an opinion rejecting our exception to the rule of announcement three months after the search of Ward's home occurred. Richards v. Wisconsin, 520 U.S. 385, 388 (1997). Because the police officers involved reasonably and in good faith relied upon the rule as it existed when the warrant was issued and executed, the court adopted the United States Supreme Court's reasoning in Illinois v. Krull and recognized a limited exception to the exclusionary rule. Ward, 231 Wis. 2d 723, ¶¶ 51-52.
¶ 50. The following year, in Eason, the court adopted the good-faith exception articulated in Leon. The search warrant in Eason provided authorization for a no-knock entry, authorization that this court determined to be unjustified by the attached affidavit. Eason, 245 Wis. 2d 206, ¶ 1. The court carefully reviewed the Court's rationale in Leon, and ultimately concluded "the good faith exception applies where the State has shown, objectively, that the police officers reasonably relied upon a warrant issued by an independent magistrate." Id., ¶ 3.
¶ 51. The court made clear that Eason did not mark the end of the exclusionary rule in Wisconsin, noting: "We would no more overrule Hoyer than we could overrule Mapp v. Ohio." Id., ¶ 57. The court also held that, for the good-faith exception to apply, the state must show that the process of obtaining the search warrant included: (1) a significant investigation; and (2) review by a government attorney or police officer trained in and knowledgeable of probable cause requirements. Id., ¶ 74. Noting that the probable cause determination was "a close case," id., ¶ 1, and that the [550]*550officers relied upon a search warrant "issued by a detached and neutral magistrate," the court concluded that the good-faith exception applied to permit the use of the evidence, id., ¶ 74.
¶ 52. Not long after Eason was decided, the state asked this court to extend the good-faith exception in the context of affidavits lacking a sworn affidavit. Tye, 248 Wis. 2d 530, ¶ 24. The court declined to extend the good-faith exception this far, holding: "The exclusionary rule applies when no oath or affirmation supports a search warrant; 'it is plainly evident that a magistrate or judge had no business issuing a warrant.'" Id. (quoting Illinois v. Gates, 462 U.S. 213, 264 (1983) (White, J., concurring)). Despite the conclusion that the warrant would have satisfied probable cause requirements had the affidavit been properly sworn, the court held that the evidence was inadmissible. Id., ¶¶ 5, 7.
3. Application of the Exclusionary Rule and Good-Faith Exception
¶ 53. Our historical overview of the exclusionary rule and good faith exception demonstrates how this court has followed the development and application of the exclusionary rule and good-faith exception articulated by the United States Supreme Court.6 Unfortunately, the facts of this case are not a neat fit with the [551]*551traditional framework under the Fourth Amendment, the exclusionary rule, or the good-faith exception. The Supreme Court has never addressed whether the good-faith exception can save evidence seized pursuant to a warrant that the judge had no authority to issue. Applying the traditional principles of the exclusionary rule and the good-faith exception, we decline to extend the good-faith exception to the facts of this case.
¶ 54. Both federal and Wisconsin case law concerning the exclusionary rule and the good-faith exception start from the presumption of a warrant issued by "a detached and neutral magistrate." Leon, 468 U.S. at 900; Eason, 245 Wis. 2d 206, ¶ 2; see also Gates, 462 U.S. at 240; Evans, 514 U.S. at 11; Krull, 480 U.S. 340, 348 (1987). Most of the case law in this area addresses search warrants issued upon affidavit by law enforcement, focusing the discussion of the judge or magistrate's role in this process on whether she abdicated her role in the process by serving as a rubber stamp for law enforcement. See Gates, 462 U.S. at 239 (discussing a magistrate's role in issuing a warrant).
[552]*552¶ 55. We have held that the "detached and neutral magistrate" requirement is necessary to "interpose the impartial judgment of a judicial officer between the citizen and the police and also between the citizen and the prosecutor, so that an individual may be secure from an improper search or an improper arrest." Walberg v. State, 73 Wis. 2d 448, 455, 243 N.W.2d 190 (1976). In this instance, the court did not have the opportunity to act as a detached and neutral magistrate, because there was no prosecutor or police action to evaluate. In most situations, a sworn affidavit is necessary for a court to act as a detached and neutral magistrate when issuing an arrest warrant. See Giordenello, 357 U.S. at 485 (probable cause and oath or affirmation requirements apply to arrest warrants); Tye, 248 Wis. 2d 530, ¶ 21 (noting the "historical importance of the oath or affirmation as the basis upon which a neutral magistrate issues a warrant"). This is true even for warrants issued in civil cases. See Soldal v. Cook County, 506 U.S. 56, 67 (1992) (Fourth Amendment protections apply in the civil context).
¶ 56. In Eason the court required additional evidence of a serious and careful process for obtaining a search warrant before permitting the good-faith exception to be invoked. The State does not argue that the Eason requirements have been met; instead it asks us to find them inapplicable under the circumstances.
¶ 57. The dissent points out that the additional Eason requirements do not apply to bench warrants issued without police involvement. Dissent, ¶ 94. We acknowledge that the Eason requirements for the good-faith exception were crafted for search warrants and may not be applicable to all warrants for arrest, especially in situations where a law enforcement agency is not in the picture.
[553]*553¶ 58. It is true that bench warrants do not require police involvement. However, civil bench warrants, like the one issued in this case, require an affidavit demonstrating the existence of the requisite cause of action, and a person may not be arrested as a remedial sanction for contempt without notice and hearing. Wis. Stat. §§ 818.03, 785.03(1)(a), 785.04(1)(b). These statutoiy requirements are intended to put the judge in a position to act as a detached and neutral magistrate with the proper facts placed before him in a manner sufficiently reliable to satisfy the constitutional requirements.
¶ 59. A judge may issue an arrest warrant for failure to appear or may summarily imprison a defendant as a punitive sanction for contempt in the "actual presence of the court" without a sworn affidavit. Wis. Stat. §§ 968.09, 785.03. A judge may do this constitutionally because the judge has personal knowledge of the facts justifying the arrest. See United States v. Evans, 574 F.2d 352, 355 (6th Cir. 1978) (discussing a personal knowledge exception to the oath or affirmation requirement).
¶ 60. Thus, the Eason requirements do not necessarily control when applying the good-faith exception to bench warrants, but they implicate relevant considerations. A judge cannot act as a detached and neutral magistrate without being presented with sufficient, reliable facts. This basic principle is why we take the oath or affirmation requirement so seriously. See Tye, 248 Wis. 2d 530, ¶ 20 (describing the "historical importance of the oath or affirmation as the basis upon which a neutral magistrate issues a warrant"). Here, there was no significant investigation or review by a government attorney. The judge acted without verified input or objective feedback. He apparently acted on impulse without the facts being properly presented to him. [554]*554Under these circumstances, the resulting warrant, which was void ab initio, cannot be saved by law enforcement good-faith.
¶ 61. Case law on the good-faith exception generally proceeds from a warrant that was valid when issued, but later determined to be lacking in probable cause. See, e.g., Leon, 468 U.S. at 903; Eason, 245 Wis. 2d 206, ¶ 55. As we have already noted, in this case the warrant was void ab initio. It had no basis in fact or law. Other courts have reached the conclusion that good faith on the part of law enforcement has no bearing where a warrant is void ab initio. See United States v. Neering, 194 F. Supp. 2d 620, 626-28 (E.D. Mich. 2002) (suppression of evidence pursuant to a warrant that was void ab initio because the magistrate's appointment had not been properly completed); Wilson, 618 N.W.2d at 515 (good-faith exception does not apply where warrant was issued by judge who had no jurisdiction in that judicial circuit); United States v. Scott, 260 F.3d 512, 513 (6th Cir. 2001) (good-faith exception cannot cure a constitutional violation because the warrant issued by a retired judge was void ab initio).
¶ 62. Our holdings in Brady and Tye further underscore the importance, as a preliminary matter, of meeting the constitutional requirements of oath or affirmation and probable cause. Brady, 130 Wis. 2d at 454; Tye, 248 Wis. 2d 530, ¶ 24. When a court issues a warrant in complete absence of one of these basic constitutional requirements, the state cannot rely on the good faith of the executing officer to overcome a judicial mistake. We have no reason to question the intentions of the circuit judge, but like the judge in Tye, he "had no business issuing a warrant" under these circumstances. Id.
[555]*555¶ 63. The goal of judicial integrity warrants some clarification. The court of appeals concluded that "[t]he act of issuing a warrant without any authority whatsoever to do so .. . is not a 'judicial' act and the attempt to clothe it as such is contrary to judicial integrity." Hess, 320 Wis. 2d 600, ¶ 30. The purpose of preserving judicial integrity is often tied directly to the purpose of deterring unlawful police conduct. Leon, 468 U.S. at 921 n.22 (citing United States v. Janis, 428 U.S. 433, 458 n.35 (1976)). But judicial integrity is implicated when a judge issues a warrant that does not comply with statutory requirements and is not supported by the constitutionally required oath or affirmation. In this case, there was no affidavit at all. In Leon, the Supreme Court held that "[a]bsent unusual circumstances, when a Fourth Amendment violation has occurred because the police have reasonably relied on a warrant issued by a detached and neutral magistrate but ultimately found to be defective, 'the integrity of the courts is not implicated.'" Leon, 468 U.S. at 921 n.22 (quoting Gates, 462 U.S. at 259 n.14 (White, J., concurring)) (emphasis added). Even were we to hold that the circuit court fulfilled Leon's "detached and neutral magistrate" requirement, this case presents those "unusual circumstances." The constitutional violation was initiated when the court issued a warrant without authority to do so, and the officer's good-faith reliance on that warrant cannot save the resulting evidence.7
¶ 64. The dissent postulates that the Supreme Court abandoned judicial integrity in Janis, 428 U.S. [556]*556433. Yet, even the dissent's quote from Janis refers to the "[p]rimary meaning of'judicial integrity.'" Id. at 458 n. 35 (emphasis added). The dissent overlooks the language leading up to the Janis quote: "To the extent that recent cases state that deterrence is the prime purpose of the exclusionary rule, and that 'judicial integrity' is a relevant, albeit subordinate factor, we hold that in this case considerations of judicial integrity do not require exclusion of the evidence." Id. (emphasis added). This language cannot reasonably be read to abandon judicial integrity and restrict the exclusionary rule solely to deterrence of law enforcement officers. The Court's statement in Leon that judicial integrity is not implicated when police rely in good faith on a warrant, "absent unusual circumstances," preserves judicial integrity as a secondary consideration when applying the exclusionary rule. Leon, 468 U.S. at 921 n.22 (quoting Gates, 462 U.S. at 259 n.14 (White, J., concurring)).
¶ 65. We do not read recent cases such as Herring and Evans as withdrawing the language from Janis and Leon suggesting that judicial integrity is a secondary consideration that may come to the fore in unusual cases. These cases simply refused to exclude evidence based on judicial integrity in the specific facts of those cases. None of the recent cases cited by the dissent involved a warrant that was per se void ab initio because the judge lacked statutory authority to issue it. Nor do they involve a fundamental defect like the complete absence of a constitutionally required sworn affidavit, which renders the warrant "invalid when issued." Tye, 248 Wis. 2d 530, ¶ 23.
¶ 66. The consideration of judicial integrity must take into account the nature of the defects in the warrant. The defects in the warrant here were not [557]*557technical irregularities or errors of judgment: The defendant's failure to cooperate with the agent in preparing a PSI was not a crime. It did not violate a court order, and it did not violate a condition of his bond. He could not have been arrested without a warrant because the defendant did not commit a crime. See Wis. Stat. § 968.07(1)(d); State v. Lange, 2009 WI 49, ¶ 19, 317 Wis. 2d 383, 766 N.W.2d 551 ("A warrantless arrest is not lawful except when supported by-probable cause."). The bench warrant civil that the court issued was void ab initio because it did not comply with any statute authorizing the court to issue a warrant. It was defective on its face because it was a civil warrant in a criminal case. It was not supported by a constitutionally required oath or affirmation. This should have been obvious because there was no affidavit at all. No law enforcement officer or agency made a significant investigation to support an affidavit; no government attorney or informed officer scrutinized the warrant for probable cause. In short, the warrant was void ab initio because it was unauthorized and defective in nearly every respect.
¶ 67. While it is easy to understand why a clerk's failure to remove a warrant from the computer system does not threaten the integrity of our judicial system, see Arizona v. Evans, 514 U.S. at 4-5, a warrant issued without statutory authority in the complete absence of the basic constitutional requirement of oath or affirmation raises more serious questions. As stated by the Sixth Circuit, "Leon presupposed that the warrant was issued by a magistrate or judge clothed in the proper legal authority .. . Indeed, Leon noted that it left 'untouched . .. the various requirements for a valid warrant.' " Scott, 260 F.3d at 515 (internal quotes and citations omitted). When fundamental constitutional [558]*558and statutory requirements for issuing a warrant are completely absent, the good-faith exception cannot save the resulting unconstitutionally obtained evidence.
IV CONCLUSION
¶ 68. We conclude that the good-faith exception to the exclusionary rule does not apply to a situation in which: (1) no facts existed that would justify an arrest without a warrant; (2) the civil arrest warrant issued by a circuit judge was void ab initio because (a) it did not comply with any statute authorizing the court to issue a warrant; and (b) it was not supported by an oath or affirmation; and (3) the court issued the warrant without the benefit of verification of the facts or scrutiny of the procedure to ensure that the judge acted as a detached and neutral magistrate.
¶ 69. The warrant here was defective on its face. Nonetheless, we cannot reasonably attribute fault to the law enforcement officer who executed the warrant. Thus, suppressing evidence obtained as a result of the unauthorized, defective warrant is necessary to preserve the integrity of the judicial process. Consequently, we affirm the decision of the court of appeals.
By the Court. — The decision of the court of appeals is affirmed.
