OPINION
¶ 1 Arizona Revised Statutes (A.R.S.) section 13-804.D (2001) directs that “[r]estitution payments ... shall not be stayed if the defendant files a notice of appeal, and the payments may be held by the court pending the outcome of an appeal.” Arizona Rule of Criminal Procedure 31.6 provides in relevant part that “[a] sentence to pay a fine or restitution shall be stayed pending appeal.” This case requires us to decide whether A.R.S. § 13-804.D and Rule 31.6 conflict and, if so, which provision controls. For the reasons stated below, we hold that these provisions conflict and that A.R.S. § 13-804.D governs because it is a valid exercise of the legislature’s rulemaking authority under the Victims’ Bill of Rights (VBR), Article 2, Section 2.1 of the Arizona Constitution.
I.
¶2 After being convicted of fraudulent schemes and artifices in violation of A.R.S. § 13-2310 (2001), and theft of $25,000 or more in violation of A.R.S. § 13-1802 (2001), petitioner Karen Marie Hansen was sentenced to concurrent terms of imprisonment and ordered to pay $65,466.03 in restitution. Consistent with A.R.S. § 31-254.D.4 (Supp. 2006), the Yavapai County Superior Court ordered Hansen to pay restitution “[f]rom 30 percent of compensation earned while in prison until paid in full or [she] is released; any balance [must be paid] within 180 days of release.” As of June 22, 2006, the Arizona Department of Corrections (DOC) had withheld $13.79 from Hansen’s wages earned while in prison and forwarded the money to the superior court. The clerk of the court distributed the money to Hansen’s victims.
¶ 3 Hansen appealed her convictions and, relying on Rule 31.6, moved the court of appeals to enjoin DOC from withholding restitution during the pendency of her appeal and to restore the money previously withheld. 1 The State opposed Hansen’s motion on the ground that A.R.S. § 13-804.D, rather than Rule 31.6, controls because the relevant subject matter is substantive and within the sole province of the legislature. Cf Ariz. Const, art. 3 (keeping “separate and distinct ... the powers properly belonging” to the separate branches of government). Conceding that Rule 31.6 and A.R.S. § 13-804.D conflict, Hansen contended that the Rule should govern because the subject matter is procedural and A.R.S. § 13-804.D therefore constitutes an impermissible legislative encroachment on this Court’s constitutional authority to promulgate rules of procedure. See Ariz. Const, art. 6, § 5, cl. 5 (conferring upon this Court the “[p]ower to make rules relative to all procedural matters in any court”).
¶ 4 In an unpublished order dated October 6, 2006, the court of appeals denied Hansen’s motion to stay her restitution payments, but ordered that all withholdings be retained by the clerk of the superior court during the pendency of Hansen’s appeal. The court of appeals subsequently issued an opinion explaining its order.
State v. Hansen,
¶ 5 Hansen petitioned for review, which we granted because this case presents an issue of statewide importance. We invited the *289 parties to submit supplemental briefs discussing whether A.R.S. § 13-804.D falls within the legislature’s authority to enact procedural rules related to victims’ rights under the VBR. We have jurisdiction under Article 6, Section 5, Clause 3 of the Arizona Constitution and Arizona Rule of Criminal Procedure 31.19.

¶ 6 Interpreting rules, statutes, and constitutional provisions raises questions of law, which we review de novo.
See Pima County v. Pima County Law Enforcement Merit Sys. Council,
A.
¶7 When construing statutes, we apply “fundamental principles of statutory construction, the cornerstone of which is the rule that the best and most reliable index of a statute’s meaning is its language and, when the language is clear and unequivocal, it is determinative of the statute’s construction.”
Deer Valley Unified Sch. Dist. No. 97 v. Houser,
¶ 8 Applying these principles, we conclude that A.R.S. § 13-804.D and Rule 31.6 cannot be harmonized. The statute and the rule contain patently contradictory instructions as to whether restitution payments are stayed pending appeal. The statute states that the payments
shall not
be stayed during an appeal, and the rule directs that a sentence to pay restitution
shall
be stayed pending appeal. Although we attempt to construe statutes and rules in a way that averts needless constitutional tension,

B.
¶ 9 Under the Arizona Constitution, the legislature possesses those powers “not expressly prohibited or granted to another branch of the government.”
Adams v. Bolin,
¶ 10 The State contends, and Hansen concedes, that if A.R.S. § 13-804.D is substantive, it indisputably governs.
See State v. Murray,
¶ 11 In 1990, the voters amended the Arizona Constitution to include the VBR.
See
Ariz. Const, art. 2, § 2.1;
State v. Roscoe,
¶ 12 The legislature’s power to promulgate rules under the VBR is not unlimited. “[T]he scope of legislative rulemaking power under the VBR extends to those rules that define, implement, preserve, and protect the specific rights unique and peculiar to ciime victims, as guaranteed and created by the VBR.”
Brown,
¶ 13 In
Brown,
we rejected an argument that the legislature exercised its rulemaking power under the VBR when it adopted statutory time limits for filing petitions for post-conviction relief that conflicted with Arizona Rule of Criminal Procedure 32.4.C.
¶ 14 We conclude that, unlike the statute we considered in
Brown,
A.R.S. § 13-804.D falls within the legislature’s rulemaking power under the VBR for several reasons. First, and most importantly, this statute affects rights unique and specific to victims. One of the rights specifically enumerated in the VBR is the right to “receive prompt restitution from the person or persons convicted of the criminal conduct that caused the victim’s loss or injury.” Ariz. Const, art. 2, § 2.1(A)8. Indeed, we have previously explained that “the right to receive prompt restitution from the perpetrator or perpetrators” is “unique and peculiar to crime victims.”
Brown,
¶ 15 Second, legislative history indicates that the legislature intended to exercise its VBR authority when it enacted A.R.S. § 13-804.D.
Cf. Brown,
¶ 16 Finally, A.R.S. § 13-804.D advances victims’ rights by permitting payments during an appeal. Rule 31.6, promulgated well before passage of the VBR, see Ariz. R.Crim. P. 31.6 (1973), automatically stays “[a] sentence to pay a fine or restitution ... pending appeal.” Conversely, A.R.S. § 13-804.D prohibits staying restitution payments and, while permitting payments to be “held by the court pending the outcome of an appeal,” abandons the automatic stay previously required under Rule 31.6. Because the statute enhances the likelihood that victims of crime will receive prompt restitution, the statute advances victims’ rights.
¶ 17 Because the legislature enacted A.R.S. § 13-804.D to protect an enumerated right in the VBR that is unique and specific to victims, and because A.R.S. § 13-804.D also advances this right, we conclude that the statute falls within the legislature’s limited rulemaking authority under the VBR. See Ariz. Const, art. 2, § 2.1(A)11, (D).
III.
¶ 18 For these reasons, we affirm the order of the court of appeals dated October 6, 2006, vacate the subsequent opinion of the court of appeals providing the rationale for its order, and remand to the court of appeals for further proceedings consistent with this opinion.
Notes
. Hansen’s underlying appeal of her conviction is pending before the court of appeals and is not at issue here.
