¶ 1 This special action arises from the trial court’s refusal to conduct a hearing pursuant to Arizona Rule of Criminal Procedure 13.5(c) and Chronis v. Steinle, 220 Ariz. 559, 208 P.3d 210 (2009). We accept jurisdiction because the issue raised involves a challenge to grand jury proceedings that will not be reviewable on appeal. State v. Moody, 208 Ariz. 424, 439-40 ¶ 31, 94 P.3d 1119, 1134-35 (2004); Francis v. Sanders, 222 Ariz. 423, 426 ¶ 9, 215 P.3d 397, 400 (App.2009). We decline to grant relief, however, because the trial court did not err in refusing to conduct the hearing.
FACTS AND PROCEDURAL HISTORY
¶2 On September 28, 2011, the Yavapai County Grand Jury indicted Juan Carlos Vicente Sanchez and three others on first-degree murder, kidnapping, conspiracy to commit first-degree murder, and conspiracy to commit kidnapping, as well as several other felonies. On December 15, 2011, Sanchez moved for a redetermination of probable cause. While the motion was pending, the State filed its Notice of Intent to Seek the Death Penalty and List of Aggravating Circumstances.
¶ 3 The trial court granted the motion for redetermination of probable cause and remanded the case to the Grand Jury. On April 20, 2012, the State presented evidence to the Grand Jury that probable cause existed to charge Sanchez with the same offenses. The Grand Jury considered the evidence and issued a True Bill against Sanchez on the charged offenses. The State then asked the Grand Jury to find that probable cause existed to allege the aggravating circumstances that would make Sanchez eligible for a death sentence. After considering the evidence, the Grand Jury issued a True Bill regarding *16each of the alleged aggravating circumstances.
¶ 4 Sanchez again moved for a redetermi-nation of probable cause, arguing that the State had presented false, misleading, and inadequate evidence to the Grand Jury on the charged offenses. He also argued that the State had erred in asking the Grand Jury to determine whether probable cause existed for the aggravating circumstances. He claimed that he was entitled to an evidentiary hearing pursuant to Rule 13.5(c) and our supreme court’s decision in Chronis v. Steinle to determine probable cause on the aggravating circumstances.
¶ 5 The State opposed the motion, arguing that the evidence presented to the Grand Jury was not false or misleading and that nothing prohibited it from presenting aggravating circumstances to the Grand Jury for a probable cause determination. The State maintained that an evidentiary hearing pursuant to Rule 13.5(c) and Chronis was necessary only when probable cause on the aggravating circumstances had not yet been determined.
¶ 6 The trial court heard argument on the motion and agreed with the State that Rule 13.5(c) and Chronis did not require a separate hearing on probable cause on the aggravating circumstances if the Grand Jury had already determined it: “I do think a probable cause determination is a probable cause determination.” On October 30, 2012, Sanchez formally requested a Chronis hearing and disclosure of the evidence supporting the aggravating circumstances, and the trial court denied the motion as moot because the Grand Jury had already determined probable cause. This special action followed.
DISCUSSION
¶ 7 We review the trial court’s denial of a motion for redetermination of probable cause for an abuse of discretion, Francis, 222 Ariz. at 426 ¶ 10, 215 P.3d at 400, but we review the interpretation of rules of procedure de novo, State v. Gutierrez, 229 Ariz. 573, 576 ¶ 19, 278 P.3d 1276, 1279 (2012). The trial court did not err in refusing to conduct an evidentiary hearing under Rule 13.5(c) and Chronis to determine probable cause on the alleged aggravating circumstances because the Grand Jury had already determined the issue by returning a True Bill on the circumstances.
¶ 8 A review of Rule 13.5(c)’s history shows why this is so. In 2002, the United States Supreme Court held in Ring v. Arizona that because the existence of any aggravating circumstance set forth in Arizona’s death penalty statute makes a defendant eligible for a death sentence, the Sixth Amendment requires that a jury determine beyond a reasonable doubt whether an aggravating circumstance exists. 536 U.S. 584, 606, 122 S.Ct. 2428, 153 L.Ed.2d 556 (2002). In light of this pronouncement, the issue arose whether the State was required to allege the aggravating circumstances in the charging document and present them to a grand jury for a probable cause determination. Chron-is, 220 Ariz. at 562 ¶ 14, 208 P.3d at 213. Our supreme court resolved this issue by adopting Rule 13.5(c). That rule provides that “[t]he filing of a notice to seek the death penalty with noticed aggravating circumstances shall amend the charging document, and no further pleading needs to be filed,” but also that “[a] defendant may challenge the legal sufficiency of an alleged aggravating circumstance by motion filed pursuant to Rule 16.” See also Chronis, 220 Ariz. at 562 ¶ 14, 208 P.3d at 213 (discussing Rule 13.5’s history). Thus, under Rule 13.5(c), aggravating circumstances need not be presented in the charging document — i.e., not be presented to a grand jury or determined in a preliminary hearing — but after an indictment or preliminary hearing on the charged offenses, a defendant may challenge an aggravating circumstance’s “legal sufficiency” by a pretrial motion under Rule 16.
¶ 9 Despite adoption of Rule 13.5(c), the issue of how aggravating circumstances should be alleged arose again in McKaney v. Foreman, 209 Ariz. 268, 100 P.3d 18 (2004). A capital defendant argued that, in light of Ring, aggravating circumstances “must be alleged in the indictment and supported by evidence of probable cause” under the United States and Arizona Constitutions. McKaney, 209 Ariz. at 269 ¶ 4, 100 P.3d at 19. A *17closely divided supreme court rejected that argument, holding that “aggravating factors essential to the imposition of a capital sentence need not be alleged in the grand jury indictment or the information in order to satisfy constitutional due process.” Id. at 273 ¶ 23, 100 P.3d at 23. The majority found that while aggravating circumstances are the “functional equivalent” of elements of the offense of capital murder, “no authority requires that aggravating factors be identified and treated as ‘essential elements of the alleged crime’ for the purpose of inclusion in a grand jury indictment or information.” Id. at 271 ¶ 15, 100 P.3d at 21. The majority found that capital defendants’ due process rights would be otherwise sufficiently protected because the Arizona Rules of Criminal Procedure assured them adequate notice of the aggravating circumstances, and the trial jury would determine the existence of the circumstances beyond a reasonable doubt. Id. at 271-72 ¶ 16,100 P.3d at 21-22.
¶ 10 The dissenting justices, however, found that because aggravating circumstances were “functional equivalents” of elements of the offense, the Arizona Constitution should be interpreted consistently with the Fifth Amendment of the United States Constitution, which has been universally interpreted to require that aggravating circumstances be presented to a grand jury in federal prosecutions. Id. at 274 ¶¶ 28-29, 100 P.3d at 24 (Hurwitz, J., and Ryan, J., dissenting in part, concurring in part). In the dissenting justices’ opinion, excusing the State from presenting aggravating circumstances to the grand jury “effectively eviscerated]” the constitutional protection of a neutral body’s determination whether the State has probable cause to bring charges. Id. at 275 ¶¶ 31-32, 100 P.3d at 25. The dissenting justices nevertheless found that the defendant was not entitled to relief for the denial of that right because he could still challenge “the legal sufficiency” of the aggravating circumstances through Rule 13.5(e): “By filing a motion under Rule 13.5(c), a defendant can obtain protection against arbitrary state action equivalent to that which he would have received had the State submitted the aggravator to a grand jury____” Id. at 276 ¶¶ 36-37, 100 P.3d at 26.
¶ 11 The supreme court affirmed this understanding of Rule 13.5(c) and “legal sufficiency” in Chronis, holding that the rule “is most reasonably interpreted as allowing for a probable cause hearing.” 220 Ariz. at 562 ¶ 15, 208 P.3d at 213. The supreme court stated that the statements in the petition to adopt Rule 13.5(e) showed that the court’s “intent in adopting the rule was to provide a right to a probable cause determination on aggravators.” Id. The supreme court explained that given this purpose of the hearing, the parties and the trial court must follow the procedures of preliminary hearings set forth in Rule 5 when conducting the hearing, which places the burden of proof on the State, but limits the determination at issue to probable cause. Id. at 562-63 ¶¶ 18, 20, 208 P.3d at 213-14.
¶ 12 With this background, Sanchez’s argument that he is entitled to a Rule 13.5(c)/Chronis hearing despite the Grand Jury’s probable cause determination is unfounded. As explained in Chronis, Rule 13.5(e)’s purpose is to allow the State to allege aggravating circumstances without showing probable cause supporting them, but then to give a defendant the right to require the State to prove probable cause at a later hearing. 220 Ariz. at 562 ¶¶ 14H5, 208 P.3d at 213. If the State chooses, however, to present the aggravating circumstances to a grand jury, even though Rule 13.5(c) permits the State to allege them after the defendant is charged, a Rule 13.5(c)/Chronis hearing is — as the trial judge recognized here — moot once the grand jury finds probable cause on the aggravating circumstances: “[A] probable cause determination is a probable cause determination.” A defendant is not entitled to a post-indictment preliminary healing to redetermine probable cause. State v. Sisneros, 137 Ariz. 323, 326, 670 P.2d 721, 724 (1983). Sanchez’s argument contradicts this settled principle.
¶ 13 Of course, the supreme court recognized in McKaney that the United States and Arizona Constitutions do not require the State to present aggravating circumstances to a grand jury. See 209 Ariz. at 271 ¶ 15, 100 P.3d at 21 (“no authority requires that *18aggravating factors be identified and treated as ‘essential elements of the alleged crime’ for the purpose of inclusion in a grand jury indictment or information”); id. at 272 ¶ 17, 100 P.3d at 22 (“All state jurisdictions with one exception have thus far held, as we hold today, that aggravating factors need not be specified or alleged in the indictment.”); id. at 273 ¶ 23, 100 P.3d at 23 (“We therefore hold that aggravating factors essential to the imposition of a capital sentence need not be alleged in the grand jury indictment or the information in order to satisfy constitutional due process.”) (emphases added). But the court did not hold that the State was prohibited from choosing to do so. Indeed, it could not so hold because the decision to proceed by indictment “is the [Sjtate’s choice.” Sisneros, 137 Ariz. at 325, 670 P.2d at 723; see also State v. Bojorquez, 111 Ariz. 549, 553, 535 P.2d 6, 10 (1975) (referring to the State’s “unfettered discretion” under Arizona Constitution article 2, section 30 “to alternatively prosecute by indictment or information”).
¶ 14 Our dissenting colleague believes that this analysis is contrary to “the explicit procedures established by the Legislature and the supreme court for alleging capital aggravators,” which, our colleague claims, bind the State to allege capital aggravating circumstances only in a post-indictment notice to seek the death penalty and an accompanying notice of aggravating circumstances. Our colleague cites as authority for this requirement Arizona Revised Statutes (“A.R.S.”) § 13-752 (West 2013) and Rule 15.1(i). Neither the statute nor the rule, however, limits the State’s constitutional discretion to present aggravating circumstances to a grand jury.
¶ 15 Sections 13-752(A) and (B) do indeed hold that a defendant may not be sentenced to death unless the State has filed a notice of intent to seek the death penalty and has given notice of aggravating circumstances before trial. And Rules 15.1(i)(l) and (2) do require the State to provide those notices within 60 days after arraignment. But neither the statutes nor the rule preclude the State from presenting aggravating circumstances to a grand jury. The State could satisfy the statutes and rule’s notice requirements by seeking an indictment for first-degree murder and a probable cause determination on aggravating circumstances.1 A proper indictment provides a defendant sufficient notice of the charges against him. See Rule 13.2(a) ([A]n indictment “shall be a plain, concise statement of the facts sufficiently definite to inform the defendant of the offense charged.”); Franzi v. Superior Court, 139 Ariz. 556, 566, 679 P.2d 1043, 1053 (1984) (“[Ojne function of the indictment is to give the defendant notice of the crime charged so that the defendant may prepare a defense.”).
¶ 16 The State could also satisfy the statute and the rule by filing a separate notice of intent to seek the death penalty and a list of aggravating circumstances while nevertheless seeking the necessary probable cause determination on the aggravating circumstances in the grand jury. This is indeed how the State proceeded in this case. Thus, our colleague’s reliance on § 13-752 and Rule 15.1(i) is misplaced. The statute and rule establish the State’s requirement to give a defendant sufficient notice that the State is seeking the death penalty based on particular aggravating circumstances. They say nothing, however, about how the defendant’s right to a probable cause determination must be satisfied.
¶ 17 That right is satisfied if the State presents the aggravating circumstances to a grand jury and the grand jury *19finds probable cause to allege those circumstances. A grand jury's function is to determine probable cause. State v. Baumann, 125 Ariz. 404, 408, 610 P.2d 38, 42 (1980) (A grand jury’s “primary function” is “determining whether probable cause exists to believe that a crime has been committed and that the individual being investigated was the one who committed it.”); State v. Sanchez, 165 Ariz. 164, 171, 797 P.2d 703, 710 (App.1990) (“The role of the grand jury is to determine whether probable cause exists to connect the accused with the commission of a crime.”). Rule 13.5(c) was adopted to provide a procedure by which a capital defendant can obtain the right to a probable cause determination on aggravating circumstances when the opportunity for that determination before the grand jury has passed. See Chronis, 220 Ariz. at 562 ¶ 14, 208 P.3d at 213 (“Providing for a later probable cause determination was thus intended to avoid certain constitutional issues.”). Indeed, by Rule 13.5(e)’s own language, the defendant’s right to this determination arises only if the State has sought to amend the charging document with aggravating circumstances. See Rule 13.5(c) (“The filing of a notice to seek the death penalty with noticed aggravating circumstances shall amend the charging document.”). When the State has afforded the defendant the right to a probable cause determination at the grand jury proceeding, however, Rule 13.5(c) and its concomitant hearing on probable cause are unnecessary because no such amendment is needed.
¶ 18 Sanchez argues, however — and our dissenting colleague apparently agrees — that a grand jury is not the proper body to consider aggravating circumstances in determining whether probable cause exists to charge criminal conduct. But nothing precludes a grand jury from determining whether probable cause exists to justify the State’s allegation of aggravating circumstances. The Fifth Amendment requires the federal government to present aggravating eircum-stances to a federal grand jury. See Jones v. United States, 526 U.S. 227, 243 n. 6, 119 S.Ct. 1215, 143 L.Ed.2d 311 (1999) (“[A]ny fact (other than a prior conviction) that increases the maximum penalty for a crime must be charged in an indictment.”). Certain precautions may be necessary to ensure that all applicable rights are protected, see McKaney, 209 Ariz. at 272-73 ¶ 21, 100 P.3d at 22-23 (questioning whether a grand jury would need to be “death-qualified” and could hear evidence of aggravating circumstances only after determining probable cause of the underlying crime),2 but grand juries are competent to determine probable cause on aggravating circumstances.
¶ 19 Sanchez also argues — and our dissenting colleague agrees — that a grand jury’s determination of probable cause is inadequate because it does not provide him with the same procedural rights as a Rule 13.5(c)/Chronis hearing does, which is conducted as a preliminary hearing. But a grand jury determination of probable cause guarantees him the same right as a Rule 13.5(c) hearing: “The purpose of a preliminary hearing and a grand jury proceeding is the same. They are to determine whether there is probable cause to believe the individual committed an offense.” State v. Neese, 126 Ariz. 499, 502, 616 P.2d 959, 962 (App. 1980); see also McKaney, 209 Ariz. at 276 ¶ 37, 100 P.3d at 26 (Hurwitz, J. and Ryan, J., dissenting in part, concurring in part) (a grand jury and a Rule 13.5(c) hearing provide equivalent protection against arbitrary state action). Although a grand jury and a preliminary hearing afford different procedural rights, both methods of determining probable cause are constitutionally proper, and a prosecutor may employ either method without violating a defendant’s due process rights. Bojorquez, 111 Ariz. at 553, 535 P.2d at 10; accord Sisneros, 137 Ariz. at 326, 670 P.2d at 724. A defendant “has no right to choose which method is used.” *20Sanchez has a right not to the procedure associated with a Rule 13.5(c)/C7mmis hearing, but to a substantive determination of probable cause.
¶ 20 In this case, the State chose to submit its allegation of aggravating circumstances to the Grand Jury instead of proceeding with a second notice of intent to seek the death penalty and list of aggravating circumstances. By doing so, and obtaining the Grand Jury’s determination that probable cause supported those circumstances, the State gave Sanchez the rights to which he was entitled. Thus, the trial court correctly refused to conduct a Rule 13.5(c)/Chronis hearing.
CONCLUSION
¶21 We accept jurisdiction of Sanchez’s special action, but deny relief. We lift this Court’s order of March 12, 2013, staying the proceedings before the trial court.
CONCURRING: ANDREW W. GOULD, Judge.. Although the indictment in this case did not list the aggravating circumstances that the Grand Jury found were supported by probable cause, the aggravating circumstances were listed in the Grand Jury transcript, to which Sanchez has access under A.R.S. § 21-411(A) and Arizona Rule of Criminal Procedure 12.8(c). See Bojor-quez, 111 Ariz. at 554, 535 P.2d at 11 (access to grand jury transcript provides discovery). Whether this was insufficient notice is not before us because Sanchez did not challenge the sufficiency of the indictment on this basis before the trial court and does not do so now. Sanchez has thus waived any objection. See State ex rel. Thomas v. Schneider, 212 Ariz. 292, 300 ¶ 36, 130 P.3d 991, 999 (App.2006) (party's failure to raise issue before trial court waives issue on special action review). In any event, the State's filing of the list of aggravating circumstances gave Sanchez actual notice of the circumstances.
. Neither of the concerns identified in McKaney exists in this case. Any failure to “death-qualify” the Grand Jury obviously did not prejudice the State, and the Grand Jury considered the aggravating circumstances only after it found probable cause on the charged offenses.
