*688 OPINION
On March 7, 1990, following a bench trial, the district court convicted appellant of one count of driving under the influence of alcohol with two or more prior convictions. NRS 484.379; NRS 484.3792(l)(c). The district court sentenced appellant to serve a term of two years in the Nevada State Prison, and fined appellant $2,000.
At sentencing, the state offered evidence of two prior convictions: (1) a Lassen County, California, conviction dated July 8, 1983; and (2) a Douglas County, Nevada, conviction dated February 10, 1990. Appellant objected to the use of the Lassen County conviction because the information incorrectly alleged that the conviction had occurred in San Mateo County, California, rather than Lassen County. The state moved to amend the information by way of interlineation to reflect the conviction actually occurred in Lassen County, rather than in San Mateo County. The state argued that the Lassen County conviction had been admitted into evidence at the preliminary hearing, and that, therefore, no prejudice to appellant would result from amending the information. After a continuation to allow briefing and to consider the matter fully, the district court overruled appellant’s objection and allowed the amendment. This appeal followed.
*689 Appellant first contends that the district court erred in permitting the state to amend the information after the verdict. Specifically, appellant asserts that, although the prior convictions used to enhance a DUI conviction are not a substantive part of the offense, “[t]he facts concerning a prior offense must be alleged” in the complaint or information, and “must also be shown at the preliminary examination . . . .” NRS 484.3792(2). Further, an information may not be amended after the verdict is rendered. See NRS 173.095(1) (authorizing amendment of the information before verdict). Accordingly, appellant argues that the district court erred in allowing the state to amend the information to reflect that his 1983 conviction was in Lassen County rather than in San Mateo County.
We do not read NRS 484.3792(2) so restrictively. Certainly, the defendant in a DUI case should be put on notice of the possible penalties facеd, and should be provided with enough information to challenge the validity of alleged prior convictions. The state must in good faith include in the information a description of each prior conviction that is as complete and accurate as possible. However, an error in the description of a prior conviction does not automatically preclude use of the prior conviction for enhancement purposes. Instead, unless the defendant can show that an omission or inaccuracy in describing a prior conviction had prejudiced him, the state is not precluded from using that prior conviction in seeking an enhancement of the defendant’s punishment.
In the instant case, no such prejudice is alleged, and none occurred. The evidence of the Lassen County conviction was introduced at the preliminary hearing; appellant could not have been surprised to see the same evidence presented at his later sentencing. Further, unless appellant had convictions in two California counties on the same datе, it is unlikely he was misled by the typographical error complained of. We conclude that the information, even without amendment, was sufficient to allow the state to use the Lassen County conviction for enhancement purposes. We therefore need not determine whether the district court erred in allowing amendment of the information.
Appellant next contends that the district court erred in considering evidence of a prior felony conviction from Douglas County, Nevada, because the evidence at sentencing did nоt comport with this court’s decision in Koenig v. State,
In light of the arguments of the parties, we have decided to make a detailed evaluation of what the state must show before a prior conviction can constitutionally be used for enhancement purposes.
The Supreme Court has repeatedly affirmed the validity of recidivist or habitual criminal statutes.
See
Spencer v. Texas,
In Burgett v. Texas,
The
Burgett
Court did not, however, place the burden of proving the constitutional validity of a prior judgment of conviction offered for enhancement purposes on the state. The prior judgment of conviction in
Burgett
raised a presumption of inva
*691
lidity on its face; the question of the state’s burden of proof with respect to a prior judgment of conviction offered for enhancement purposes was simply not before, and not addressed by the Court. This point is evidenced by the fact that the Court distinguished the
Burgett
situation from its earlier decision in Spencer v. Texas,
In summary, Burgett prohibits the states from using a prior felony conviction for any purpose if the record of that conviction raises an unrebutted presumption that the prior conviction was obtained in violation of a specific federal constitutional right. Burgett does not prohibit the states from relying for enhancement purposes on presumptively valid prior judgments of conviction, nor does it place on the states the burden of proving that a presumptively valid judgment of conviction offered for enhancement purposes is not subject to challenge on any constitutional basis.
Later, in Baldasar v. Illinois,
Although the United States Supreme Court has not addressed the question of what the state’s burden is with respect to prior convictions offered for enhancement purposes, other courts have. For example, United States v. Gallman,
In discussing Gallman’s contention, the court of appeals stated, “once the government has shown that a defendant has three prior ‘violent felony’ convictions, the burden rests with the defendant to show that the conviction was unconstitutional .... Thus, a defendant can overcome thе government’s proof of a conviction, but only if he musters evidence of that conviction’s unconstitutionality.”
Gallman,
In Allen v. State,
The сourt first stated the well established rule that a duly entered judgment of conviction is presumed to be valid.
Id.
at 357. The court then held that a judgment of conviction is not invalid simply because it does not affirmatively demonstrate that constitutional requirements had been satisfied.
Id.
at 363. Relying on
Burgett
and
Baldasar,
the court determined that a defendant must be allowed to challenge the constitutional sufficiency of a prior judgment of conviction in any proceeding where that judgment is offered by the state for enhancement purposes. The court held, however, that in any challеnge to “the validity of prior convictions, the defendant has the burden of proving the alleged grounds by a preponderance of the evidence .... In addition, the defendant must prove by competent evidence that there was, in fact, no knowing and voluntary waiver of rights on his part.”
Allen,
Other state and federal courts are in accord with the law as stated in
Gallman
and
Allen. See, e.g.,
Tuitt v. Fair,
Although there are some differences in approach between different courts, there seems to be broad support for at least a few general propositions. First, a judgment of conviction is entitled to a presumption of regularity. While it is true that courts may not imply a waiver of constitutional rights from a silent record, it is also true that courts should not imply a constitutional deficiency in a judgment of convictiоn from a silent record. If the state produces valid records of a judgment of conviction which do not, on their face, raise a presumption of constitutional deficiency, then the defendant has the burden of presenting evidence rebutting the presumption of regularity given to a judgment of conviction. 2 In order to rebut that presumption of regularity, the defendant must make out a prima facie case that there is a constitutional deficiency in the judgment of conviction. If the defendant succeeds in overcoming the presumрtion of regularity given to the judgment of conviction, then the state has the burden of going forward with evidence to overcome the defendant’s prima facie case. Ultimately, the issue is to be decided in favor of the party producing a preponderance of the evidence.
We turn now to Nevada law. In Hamlet v. State,
In Anglin v. State,
During the forgеry trial and also at the habitual hearing, the appellant endeavored to show that several of his prior felony convictions were constitutionally infirm for one reason or another. Once identity is established, NRS 207.010(8) declares that “presentation of an exemplified copy of a felony conviction shall be prima facie evidence of conviction of a prior felony.” Accordingly, the evidentiary items contained in the exhibit (type of prior felony, where committed, identity of sentencing court, whether defendant wаs represented by counsel or had waived counsel, etc.) are prima facie evidence of the facts the exhibit purports to show, and the trial court may accept that evidence and reject the defendant’s attempted contradiction of it. Of course, the court may not rely upon the exemplified record, either to impeach or enhance punishment, when a constitutional infirmity appears from the face of the record (for example: that the defendant was not represented by cоunsel nor had he waived counsel, Burgett v. Texas, supra). If the infirmity does not so appear, the court may rely upon the exemplified record and make its determination therefrom.
Anglin,
*695
In Halbower v. State,
In Scott v. State,
Finally, in Koenig v. State,
*696 This Court, following the lead of the U.S. Supreme Court, has set forth requirements for a guilty plea to be constitutionally tendered. In Scott v. State,97 Nev. 318 ,630 P.2d 257 (1981), Halbower v. State,96 Nev. 210 ,606 P.2d 536 (1980), and Anglin v. State,86 Nev. 70 ,464 P.2d 504 (1970), we held that in felony cases, an official court record must exist showing that the defendant was apprised of his constitutional rights, understood and waived them, that there were no threats or promises that induced the guilty plea, that the defendant understood the consequences of the plea in terms of the range of punishment and understood the elements of the offense or made factual admissions evincing commission of the offensе. See also Hanley v. State,97 Nev. 130 ,624 P.2d 1387 (1981); NRS 174.035.
Koenig,
Hanley, relied on by this court in Koenig, contains a list of things which a plea canvass should affirmatively show in order for a felony judgment of conviction to pass constitutional scrutiny. 6 The quoted language from Koenig, above, is essentially a paraphrase of the Hanley list.
Hanley, however, did not deal with the use of prior convictions in the context of enhancing a later sentence. Hanley dealt with the issue of a collateral attack on a conviction obtained through a guilty plea by a defendant who wished to have that guilty plea set aside. Thus, the burden of proof was clearly on the defendant, and the defendant failed to carry that burden because the record of the proceeding demonstrated that the plea was valid. Nothing in Hanley purported to place on the state the burden of proving that a prior judgment of conviction offered for enhancement purposes was obtained as a result of a knowing and voluntary waiver of all the constitutional rights enumerated in Hanley and Koenig.
By reading the Hanley requirements into Anglin, Halbower, and Scott, this court’s opinion has been read by some, including the parties to this action, as placing on the state the initial burden of proving the validity of prior convictions offered for enhancement purposes. Koenig placed no such burden on the state. The language of Koenig is cоrrect, in that it states what must be proven in a contested case involving the use of a prior felony conviction for enhancement purposes. Koenig does not, however, shift to the state the defendant’s initial burden of demonstrating a constitutional infirmity in a presumptively valid judgment of *697 conviction. As noted above, the state’s burden to go forward with evidence to prove the validity of a prior felony judgment of conviction does not arise until the defendant has presented sufficient evidence to rebut the presumption of validity afforded all judgments of conviction.
Consequently, in
Koenig
we held, because of the informal nature of the prosecution of misdemeanor cases, that the stringent standard of review used in felony cases should not apply in misdemeanor cases. We further held that, in order to rely on a prior misdemeanor judgment of conviction for enhancement purposes, the state had the burden of proving either that the defendant was represented by counsel or validly waived that right, and that the spirit of constitutional principles was respected in the prior misdemeаnor proceedings. Although
Koenig
is silent with respect to when the state’s burden of proof arises, i.e., initially or only after a defendant has rebutted the presumption of validity of a judgment of conviction, we have subsequently, consistently required the state to initially shoulder this burden when relying on a prior misdemeanor conviction for enhancement purposes.
See, e.g.,
Pettipas v. State,
We conclude, therefore, that Koenig sets out the proper standard for the use of prior misdemeanor convictions in enhancing the punishment for a subsequent offense. To the extent that Koenig places a slightly higher burden of proof on the state in using misdemeanor convictions, this higher burden of proof is justified by the fact that a misdemeanor conviction is generally not viewed with the same gravity as a felony conviction. Thus, misdemeanor convictions are routinely entered without the benefit of counsel; a rare occurrence in felony cases. Accordingly, we feel it appropriate in misdemeanor cases to require the state to affirmatively show either that counsel was present or that the right to counsel was validly waived, and that the spirit of cоnstitutional principles was respected in the prior misdemeanor proceedings before the record of the prior misdemeanor may be used for enhancement purposes.
The use of prior felony convictions for enhancement purposes is governed by a different standard. Consistent with established Nevada law, in order to use a prior felony conviction for enhancement purposes, the state’s initial burden of production shall be satisfied if the state presents
prima facie
evidence of the existence of the prior conviction.
See
NRS 207.010(8); Pettipas v. State,
If the record does not raise a presumption of constitutional infirmity, the defendant is nonetheless free to present evidence tending to rebut the presumption of regularity afforded to a criminal conviction. If a defendant can establish, by a preponderance of the evidence, that the prior conviction is constitutionally infirm, then that conviction may not be used to enhance the defendant’s sentence.
See, e.g.,
Crawford v. State,
In the instant cаse, no constitutional infirmity appears on the face of appellant’s prior Douglas County conviction, either under our prior holdings or under the holding announced today. The record demonstrates, for example, that appellant was represented by counsel throughout the Douglas County proceedings. Further, appellant made no attempt in the district court to show that his prior conviction had not been constitutionally obtained. Instead, appellant simply argued that the state had not proved that appellant’s prior conviction had been constitutionally obtained. Thus, appellant failed in the district court to rebut the presumption that the prior conviction was constitutionally obtained. Therefore, the district court properly relied on the record of this conviction in enhancing appellant’s sentence. Accordingly, we affirm in all respects the judgment of conviction.
Notes
The documents submitted by the state as evidence of the Douglas County conviction consist of a certified copy of the judgment of conviction, one page of the minutes of preliminary proceedings in the Justice’s Court of the East Fork Township, Douglas County, and a bench warrant for appellant’s arrest based on a failure to appear. These documents affirmatively demonstrate that appellant was represented by counsel when he entered his plea. They are otherwise silent with respect to appellant’s constitutional rights.
NRS 207.010(8) provides that “[a] certified copy of a felony conviction is prima facie evidence of conviction of а prior felony.”
The
Anglin
opinion continued by noting that, “[fjrom time to time there may be an occasion where such prior conviction is in fact constitutionally infirm, but such infirmity is not reflected upon the face of the exemplified record.”
Anglin,
The apparent requirement in Anglin that a judgment of conviction valid on its face be challenged, if at all, in a separate proceeding is too harsh. Instead, as noted in the authorities cited above, a defendant must be afforded an opportunity in any proceeding in which a prior judgment of conviction is offered for enhancement purposes to challenge the constitutional validity of the prior conviction. We do not believe that the language employed in Anglin was intended to prevent a criminal defendant from challenging in the action in which a prior judgment of conviction is offered the constitutional sufficiency of that prior judgment. To the extent that Anglin can be so read, it is specifically disapproved.
It must be kept in mind, of course, that Scott is not an enhancement case. The prior convictions in Scott were used for impeachment.
Unfortunately, some language in Scott could be read as requiring the state to affirmatively show the presence of counsel and that the prior convictions based on guilty pleas were constitutionally obtained. Such a reading of Scott is not required by the facts of Scott, and is inconsistent with the specific holding of Scott.
This court has replaced the formally structured analysis of
Hanley
in reviewing the validity of a felony conviction on collateral attack with an approach that focuses on the state of the record as a whole.
See
Bryant v. State,
The appropriate standard of review in evaluating the validity of a prior felony conviction pursuant to a guilty plea is set forth in our opinion in Bryant.
