The DeKalb County district attorney brought a declaratory judgment action against the county’s magistrate judges seeking guidance regarding a dispute on the proper evidentiary standards for establishing probable cause at preliminary hearings. The trial court issued a declaratory judgment in the district attorney’s favor, and the Court of Appeals affirmed. We granted the petition for writ of certiorari to consider whether declaratory judgment is an appropriate remedy for challenging evidentiary policies or practices at preliminary hearings. Because this dispute is not a civil case that presents a justiciable controversy and declaratory relief would not provide any more guidance or certainty than current case law, we conclude that declaratory relief is not an appropriate remedy. Accordingly, we reverse.
This appeal is the second appearance of this case before this Court. In 2007, then-District Attorney Gwendolyn Keyes Fleming filed petitions for the writs of mandamus and prohibition against the Magistrate Court of DeKalb County and four judges, alleging that the court had a policy declaring that hearsay evidence alone was insufficient to establish probable cause at preliminary hearings. The trial court ruled that a magistrate judge did not have the discretion to refuse to admit hearsay evidence and that a judge could find probable cause based on hearsay alone. This Court granted the magistrate court’s interlocutory application and reversed, concluding that the trial court erred in considering the petitions because the underlying subject matter concerned rulings made in criminal prosecutions from which the State could not appeal. Magistrate Court of DeKalb County v. Fleming, 284 Ga. 457 (667 SE2d 356) (2008) (Fleming I).
Subsequently, the district attorney amended her complaint to add a declaratory judgment claim and all current magistrate judges *670as parties. She asserts that the magistrate judges’ subjective interpretation of the law leaves the district attorney uncertain about the evidentiary standard she must meet to establish probable cause at a preliminary hearing. Granting the district attorney’s motion for summary judgment, the trial court concluded that the magistrate judges lack discretion to refuse the admission of hearsay evidence and are required to find probable cause if hearsay alone supports it. The judges appealed, and the Court of Appeals affirmed on that issue. Bethel v. Fleming, 310 Ga. App. 717 (1) (713 SE2d 900) (2011) (Fleming II). The court found that “a declaratory judgment regarding the proper evidentiary standards in preliminary hearings is authorized and necessary in this case, and further, that magistrate judges are required to admit and weigh hearsay evidence in preliminary hearings.” Id. at 724.
1. The State Declaratory Judgment Act gives superior courts the power to declare rights and other legal relations of any interested party in “cases of actual controversy” under OCGA § 9-4-2 (a) and “in any civil case in which it appears to the court that the ends of justice require that the declaration should be made.” OCGA § 9-4-2 (b). “The words ‘actual controversy’ mean a justiciable controversy where there are interested parties asserting adverse claims on an accrued set of facts.” Cramer v. Spalding County, 261 Ga. 570, 572 (2) (409 SE2d 30) (1991). “For a controversy to justify the making of a declaration, it must include a right claimed by one party and denied by the other, and not merely a question as to the abstract meaning or validity of a statute.” Pilgrim v. First Nat. Bank, 235 Ga. 172, 174 (219 SE2d 135) (1975).
This dispute over the proper evidentiary standard to apply at preliminary hearings is not a controversy between two adverse parties. A judge acting in an official capacity in a criminal case is not an adverse party with interests antagonistic to those of the State or the defendant, but instead serves in the role of a neutral decision maker. See Gerstein v. Pugh, 420 U. S. 103, 114 (95 SC 854, 43 LE2d 54) (1975) (detached judgment of a neutral magistrate is required to restrain suspect for extended period following arrest); see also State ex rel. Edmisten v. Tucker, 323 SE2d 294 (NC 1984) (disallowing attorney general’s declaratory judgment action against district court judges who had ruled statute was unconstitutional because they were not persons with an adverse interest to the attorney general or people of the state). We have previously rejected a sheriff’s declaratory judgment action challenging a county grand jury’s presentment that he was failing to enforce state laws on the sale of alcoholic beverages. Cook v. Sikes, 210 Ga. 722 (82 SE2d 641) (1954). “The grand jury as a body and its members individually, being an arm of the law and a *671part of the machinery of government, are not subject to question in any court for its or their action in the performance of grand jury duties.” Id. at 727. Similarly, a prosecutor may not through a declaratory judgment action challenge the evidentiary rulings and legal interpretations of judges in performing their official duties at a court hearing.
2. Besides cases involving actual controversies, the superior courts have the power to settle justiciable controversies of a civil nature when it appears that the ends of justice require that a declaration be made. Under OCGA § 9-4-2 (b), a declaratory judgment may be issued when circumstances show the necessity for a decision “to guide and protect a party from uncertainty and insecurity with regard to the propriety of some future act or conduct.” Baker v. City of Marietta, 271 Ga. 210, 215 (1) (518 SE2d 879) (1999); accord Calvary Independent Baptist Church v. City of Rome, 208 Ga. 312, 314 (3) (66 SE2d 726) (1951). The petition fails here because the controversy is of a criminal nature and the district attorney has failed to show a need for guidance beyond existing case law.
(a) In the first appeal of this case, we reversed the trial court’s ruling on the ground that the underlying subject matter concerned rulings in criminal prosecutions — a judge’s dismissal of charges at a preliminary hearing — from which the State cannot appeal. “Here, the State, in the person of the District Attorney, has attempted to avoid this restriction by attacking the alleged [court] policy resulting in such dismissals through the device of a writ of mandamus and prohibition.” Fleming I, 284 Ga. at 458. We concluded that the trial court should have dismissed the petitions rather than considering them on their merits.
Although the district attorney attempts to recast her complaint as a civil case, we again conclude that the underlying decisions that are being challenged in this declaratory judgment action are evidentiary rulings in criminal cases that are not subject to appeal. The State of Georgia has a limited right to appeal in criminal cases. State v. Tyson, 273 Ga. 690 (1) (544 SE2d 444) (2001). OCGA § 5-7-1 sets out nine instances in which the State may file an appeal in a criminal case and does not provide for an appeal from the magistrate court’s decision dismissing charges for lack of probable cause. Cf. OCGA § 5-7-1 (a) (1) (State may appeal from an order, decision, or judgment dismissing any indictment or accusation).
In this appeal, the district attorney is challenging the policies and practices of magistrate judges on the admissibility of hearsay evidence at a preliminary hearing, a pretrial criminal proceeding. Looking at the substance of the declaratory judgment claim, the underlying subject matter concerns the prosecution of suspects accused *672of crimes. Defendants are entitled to a preliminary hearing if they are in jail awaiting disposition of their case or they have significant restrictions on their freedom while out on bond. Wayne M. Purdom, Ga. Magistrate Court Handbook § 11:1 (a) (2011). The purpose of the preliminary hearing is “to authorize the keeping in custody of one accused with probable cause of committing a crime until the grand jury determines whether he should stand trial.” Phillips v. Stynchcombe, 231 Ga. 430, 432 (1) (202 SE2d 26) (1973). The magistrate binds the accused over to the grand jury if there is probable cause to believe the suspect is guilty of the crime charged. State v. Middle-brooks, 236 Ga. 52 (1) (222 SE2d 343) (1976). The State does not have the right to directly appeal the judges’ probable cause decisions and is attempting in this case to circumvent the appellate procedure for seeking review of criminal rulings. We conclude the State cannot indirectly do what it does not have the authority to do directly. See Howard v. Lane, 276 Ga. 688, 689 (581 SE2d 1) (2003) (dismissing district attorney’s appeal of denial of a petition for writ of prohibition because State did not have ability to appeal ruling in criminal case).
(b) Previously, this Court held that the Sixth Amendment right to confront witnesses at trial does not apply to a preliminary hearing. Gresham v. Edwards, 281 Ga. 881 (644 SE2d 122) (2007), overruled on other grounds by Brown v. Crawford, 289 Ga. 722 (715 SE2d 132) (2011). In Gresham, we rejected the defendant’s argument that he was denied his constitutional right of confrontation when the only witness, the investigating detective, was permitted to give hearsay testimony at the preliminary hearing. Id. at 883; see Uniform Magistrate Court Rule 25.2 (C) (1) (“rules of evidence shall apply except that hearsay may be allowed”). See generally Ga. Magistrate Court Handbook §§ 11.5, 11.8 (hearsay may form the basis for a finding of probable cause to bind over the accused, but “only when found to be reliable, a concept which is not susceptible to clear lines”).
Moreover, the magistrate judges concede that the new Evidence Code will eliminate the uncertainty that they have claimed exists. Effective January 1, 2013, OCGA § 24-1-2 (d) (1) expressly provides, “In criminal commitment or preliminary hearings in any court, the rules of evidence shall apply except that hearsay shall be admissible.” See also OCGA § 17-7-28 (“The court of inquiry shall hear all legal evidence submitted by either party. . . . The rules of evidence shall apply except that hearsay shall be admissible.”).
At oral argument, the district attorney was unable to articulate how a judgment declaring the applicable evidentiary standard would provide any more guidance than existing case law or relieve her office of the uncertainty that she claims exists from the magistrate judges’ failure to follow that law. If the magistrate judges are not following *673the law as stated in appellate court decisions, then it is unclear how a superior court’s declaration of the law would “guide and protect” the State from uncertainty regarding future rulings in the magistrate court.
3. Contrary to the opinion of the Court of Appeals, this Court did not rule previously that a declaratory judgment complaint would have been proper in this case. See Fleming II, 310 Ga. App. at 719. In Fleming I, a dissenting justice found that the district attorney’s claims, when “properly construed,” asserted a claim for declaratory judgment relief. Fleming I, 284 Ga. at 459 (Sears, C. J., dissenting). In response, the majority opinion concluded that “[t]his is not a declaratory judgment action” because the district attorney was not seeking guidance, but instead “sought an order prohibiting [the magistrate court] from applying its hearsay evidentiary rule and mandating that the interpretation of the rule set forth by Fleming be used.” Id. at 458-459. In rejecting the dissent’s characterization of the claim, we were not sanctioning the use of a declaratory judgment action in the case.
Although the district attorney cannot appeal the probable cause rulings of the magistrate judges, the State is not without a remedy. On a case-by-case basis, the district attorney has the option of presenting additional evidence to the same judge, initiating a new prosecution for the same offense, or seeking an indictment before the grand jury. See Johnson v. State, 242 Ga. 822 (4) (251 SE2d 563) (1979) (grand jury is not bound by charge stated in magistrate’s bindover order in determining offenses that have been committed); Wells v. Stynchcombe, 231 Ga. 199 (200 SE2d 745) (1973) (dismissal of charges based on lack of probable cause does not bar subsequent indictment). See generally 4 Wayne R. LaFave et al., Criminal Procedure, § 14.3 (c) (3d ed. 2011) (describing ways that prosecutors seek to overcome a magistrate’s dismissal at a preliminary hearing).
The concurring opinion seeks to advise the district attorney and the public on broader remedies potentially available “against judges who consistently or willfully fail to follow clear and binding legal rules and precedents.” While that opinion correctly points out that the Georgia Code of Judicial Conduct requires judges to be “faithful to the law and maintain professional competence in it,” Canon 3 (B) (2), the line between a judge’s willful failure to follow binding legal precedent and a good faith effort to interpret and apply that same law is not always clear. We caution that our discussion should not be viewed as inviting, encouraging, or suggesting that parties file an ethics complaint based solely on a disagreement with a judge’s ruling in their case on the proper interpretation of the law. This remedy is not available for a judge’s “mere decisional or judgmental errors,” *674mistakes in the interpretation of statutes, or misjudgments in the exercise of discretionary powers. See In the Matter of Inquiry Concerning a Judge, 265 Ga. 843, 851 (5) (462 SE2d 728) (1995). More systemic wrongdoing is required to prove judicial incompetence. See In the Matter of Inquiry Concerning a Judge No. 94-70, 265 Ga. 326, 328 (1) (454 SE2d 780) (1995) (defining “ ‘willful misconduct in office’ to mean actions taken in bad faith by the judge acting in her judicial capacity”); see also In the Matter of Inquiry Concerning a Judge, 275 Ga. 404, 408-409 (1) (566 SE2d 310) (2002) (removing judge from office for demonstrating a lack of competence in areas of law related to the discharge of his fundamental duties, telephoning an attorney’s client to propose a settlement in a case, and retaliating against a subordinate judge); In the Matter of Inquiry Concerning a Judge, 265 Ga. 843, 850-851 (5) (462 SE2d 728) (1995) (removing judge from office for refusing to set appeals bonds when law required it, issuing bench warrants for arrests without probable cause, and forcing a defendant to enter a guilty plea in the absence of counsel).
4. In conclusion, this case is not a controversy between adverse parties or a civil case in which the ends of justice require a declaration to provide guidance or eliminate uncertainty. Therefore, we hold the district attorney does not have the right to bring a declaratory judgment action to obtain review of the probable cause decisions of magistrate judges at preliminary hearings.
Judgment reversed.
