AMENDED OPINION
¶ 1 In
State v. Reagan,
I.
¶2 In 1997, the State charged defendant McCann with aggravated DUI, which is established if a person commits a DUI offense within sixty months оf two prior DUI convictions. See Ajriz.Rev.StatAnn. (A.R.S.) § 28-1383.A.2 (West Supp.1999) (formerly A.R.S. § 28-697 A 2). During trial, the court admitted into evidence certified copies of McCann’s two prior DUI convictions. The records pertaining to his 1995 DUI conviction in the Tucson City Court do not disclose whether McCann wаs represented by counsel or had validly waived his right to counsel.
¶ 3 McCann objected, claiming the State had not “authenticated” the 1995 DUI conviction. He also unsuccessfully moved for a Rule 20 judgment of acquittal based on the fact that the court reсords from his 1995 DUI conviction failed to show conclusively that he was represented by or had waived counsel. Therefore, he argued, the State could not use the prior conviction to satisfy an element of the offense of aggravated DUI. 1
¶ 4 The court of appeals modified McCann’s conviction and remanded for re-sentencing. Although the court of appeals held for McCann, it noted that “[t]he state’s argument is not without merit,” but regarded our decision in Reagan as controlling. State v. McCann, 2 CA-CR 98-0019, slip op. at 4 (Ariz.App. May 18, 1999).
¶5 The State then petitioned this Court and we granted review. Because this issue involves the interpretation of both the Arizona and Federal Constitutions, we review the trial court’s decision de novo.

¶ 6 In
Reagan,
we essentially adopted an exception to the presumption of regularity that attaches to final judgments and presumes that judgments were constitutionally obtained. The presumption is “deeply rooted in our jurisprudenсe ... even when the question is waiver of constitutional rights.”
Parke,
¶ 7 Our
Reagan
decision relied upon
Burgett v. Texas,
¶8 In 1992, the United States Supreme Court reconsidered
Burgett
in
Parke v. Ra-ley,
¶ 9 In upholding the statute, the Court held that
“Boykin
does not prohibit a state court from presuming, at least initially, that a final judgment of conviction offered for purposes of sentence enhancement was vаlidly obtained.”
Parke,
¶ 10 The defendant in Parke also challenged the Kentucky statute on the ground that it assigned to criminal defendants a burden of production. Addressing this point, the Court said, “[Ejven when a collateral attack on a final conviction rests on constitutional grounds, the presumption of regularity that attaches to final judgments makes it appropriate to assign a proof burden to the defendant.” Id.

¶ 11 After the Court’s
Parke
decision, many of our sister jurisdictions adopted the presumption of regularity for prior convictions used to enhance sentences or as elements of a crime. For instance, in
Massachusetts v. Lopez,
Many other States have specifically relied on the Parke decision to reject collateral *30 challenges to long-closed convictions by plea where sentencing еnhancement is involved. We conclude that a collateral challenge, like the defendant’s, to a prior conviction by guilty plea, if the challenge is to advance at all, must be accompanied by sufficient credible and reliable evidence to rebut a presumption that the prior conviction was valid. If a defendant meets this burden, then an evidentiary hearing may be warranted at which the burden will be on the Commonwealth to show that the defendant’s plea proceedings were conducted in a way that protected his constitutional rights.
(Footnote omitted.)
¶ 12 The Virginia Supreme Court addressed the same issue in
Harris v. Virginia,
When sentence enhancement is an issue, the Commonwealth has the burden of proving the existence of a defendant’s pri- or, valid convictions, and it is assisted with this burden by the “presumption of regularity.” Because every final judgment of a court of competent jurisdiction is presumed “to have been rightly done,” a “final” criminal conviction is entitled to a “presumption of regularity” when challenged collaterally, even on the ground that it was constitutionally invalid. Thus, if the Commonwealth offers evidence sufficient to prove the existence of a defendant’s prior criminal conviction, a presumption arises that the prior conviction was obtained in compliance with the defendant’s right to counsel under the Sixth Amendment.

B.
¶ 13 The same reasoning that led other jurisdictions to follow the
Parke
decision аpplies in Arizona. Our case law and rules of criminal procedure have protected criminal defendants’ constitutional right to counsel for more than a quarter of a century. For example, in
State v. Anderson,
¶ 14 At the time we decided
Reagan,
it was entirely possible that a prior conviction involved proceedings in which the defendant neither had counsel nor validly waived his right to counsel. Our insistence for nearly thirty years that criminal dеfendants’ right to counsel be enforced, however, makes it unlikely that final judgments entered during those years were obtained without affording a defendant his right to counsel. We have every reason to believe that our trial courts follow the directives of this Court and the United States Supreme Court to assure that
Boykin
rights are fully protected. Thus, the reason for excluding prior final judgments used to enhance sentences or as elements of a crime from the rale of presumptive regularity no longer exists.
See Fernandez v. Romo,
¶ 15 We therefore overrule
State v. Reagan,
¶ 16 Our holding is limited; it changes only the presumption that attaches to prior final judgments. Reagan presumed prior convictions invalid for failure tо afford the right to counsel. Our holding today presumes prior final judgments valid. We emphasize that our ruling does not lessen the burden on the State, which retains the burden of establishing that a prior conviction is constitutionally valid, whether it is used as a sentence enhаncement or as an element of a crime. 4
¶ 17 Nor does our decision deprive defendants of their right to attack invalid prior convictions. In cases in which a judgment of conviction results from the violation of constitutional rights, the conviction cannot be used either to establish an element of an offense or for purposes of sentence enhancement. Thus, prior convictions may be used by the State only if constitutionally valid.
IV.
¶ 18 We granted McCann’s motion for reconsideration of our оriginal opinion,
State v. McCann,
¶ 19 We therefore vacate the decision of the court of appeals and affirm the judgment of the superior court.
Notes
. McCann has never argued that he was in fact unrepresented or that any waivеr of counsel was involuntary. Rather, he bases his argument on the fact that the record of the 1995 DUI conviction does not establish representation or valid waiver.
. See, e.g.,
State v. Renaud,
. Other states also have adopted the “burden shifting” holding of
Parke v. Raley. See, e.g., Harris v. Georgia,
. The parties suggest that deciding whеther the presumption of regularity attaches to a final judgment depends upon whether the prior conviction is used to enhance a sentence or to establish an element of a crime. The State would attach the presumption of regularity at least to judgments used to establish an element of the crime; McCann argues the presumption attaches, if at all, only if the State relies upon the judgment to enhance a sentence. We reject that distinction, for which we discern no disciрlined basis. The validity of a prior judgment depends upon the procedures used to procure the judgment, not upon the use to which the judgment is put.
. The defendant has challenged neither the sufficiency of the evidence to support the current DUI conviction nor the constitutionality of his 1993 DUI conviction.
