INTRODUCTION
The State appeals from an order of the district court for Stanton County in a separate proceeding filed by Marsha K. *176 Louthan in which she challenged, for purposes of penalty enhancement, the validity of a prior conviction for driving under the influence of alcoholic liquor (DUI). Reversing an order of the county court for Stanton County, the district court held that because the record failed to disclose that Louthan expressly waived certain constitutional rights when she entered her guilty pleа on February 28, 1994, the conviction entered on such plea was invalid and could not be used for enhancement purposes. We reverse, and remand with directions to dismiss.
FACTS AND PROCEDURAL BACKGROUND
On February 9, 1998, after being charged with second-offense DUI in Cuming County, Louthan filed a petition for relief in a separate proceeding in the county court for Stanton County, seeking a determination that her 1994 conviction by that court for first-offense DUI was invalid for enhancement purposes. At a hearing on Louthan’s petition, the county court toоk judicial notice of the record from the 1994 proceeding. The record included a completed checklist signed by the county judge and filed when Louthan entered her guilty plea and was convicted, but it did not include a verbatim transcription of that proceeding.
According to the checklist, Louthan appeared with counsel on February 28,1994, and was advised of the nature of the charges and the possible penalties. The court advised Louthan of the “[pjresumption of innocence and right to rеmain silent,” the “[r]ight to a jury trial with burden on State to prove its case beyond a reasonable doubt ... to confront & cross examine State’s witnesses, and to call and subpoena witnesses,” and “[t]o have all proceedings recorded and to use the record for appeal.” Louthan was advised of the possible pleas and the consequences of pleading not guilty, pleading guilty, or standing mute. Louthan entered a plea of guilty, and the court found that the plea had a factual basis and was “frеely, voluntarily, and intelligently made with a full understanding of the charges and possible penalties.” The checklist included a finding of guilt beyond a reasonable doubt, a waiver of the right of allocution, and a sentence consisting of a $200 fine, costs, and probation.
Louthan’s counsel argued that the 1994 conviction should be held invalid for purposes of enhancement because the checklist
*177
did not include an express waiver of the right to confront witnesses, the right to a jury trial, and the privilege against self-incrimination, as required by
State
v.
Hays,
It would be impossible for the Court to make that finding without determining in advance all of those things which Hays says has to be done in order to find and adjudge the defendant guilty. It is the Court’s opinion that that finding is an affirmative showing that those facts and the things required in Hays have taken place. There was an adjudication of guilt. The Court will deny, as I indicated, [the petition] for those reasons. To hold otherwise would indicate that the Court makes no intelligent decisions at all.
Louthan appealed to the district court, which held that the record failed “to disclose that [Louthan] expressly waived her constitutional right to confront witnesses, right to jury trial and privilege against self-incrimination when she entered her guilty plea on February 28, 1994, and as such same is constitutionally invalid for purposes of enhancement.” The State perfected this appeal and successfully petitioned to bypass the Nebraska Court of Appeals.
ASSIGNMENTS OF ERROR
The State assigns, rephrased, that the district court erred in determining that the Stanton County DUI conviction was invalid for enhancement purposes and in determining that the county court had jurisdiction to maintain a separate proceeding.
STANDARD OF REVIEW
The State’s assignments of error present questions of law. When reviewing a question of law, an appellate court reaches a conclusion independent of the lower court’s ruling.
Teters
v.
Scottsbluff Public Schools,
*178 ANALYSIS
“Statutes that punish recidivists more severely than first offenders have a long tradition in this country that dates back to colonial times.”
Parke
v.
Raley,
For each conviction under this section, the court shall as part of the judgment of conviction make a finding on the record as to the number of the defendant’s prior convictions under this section and under a city or village ordinance enacted pursuant to this section in the twelve years prior to the date оf the current conviction. The defendant shall be given the opportunity to review the record of his or her prior convictions, bring mitigating facts to the attention of the court prior to sentencing, and make objections on the record regarding the validity of such prior convictions.
Determining the validity of prior DUI convictions for purposes of sentence enhancement implicates evolving principles of law by which we must define the point at which the interest of the State in the finality of judgments of conviction must yield to the due process rights of an accused. A starting point for this
*179
analysis is
Burgett
v.
Texas,
This court first addressed
Boykin
in
State
v.
Turner,
[A] guilty plea is valid only if the record affirmatively shows that a defendant understands that by pleading guilty he waives his right to cоnfront witnesses against him, his right to a jury trial, and his privilege against self-incrimination, or otherwise affirmatively shows an express waiver of said rights. Thus, to support a finding that a plea of guilty or nolo contendere has been voluntarily and intelligently made, the court must (1) inform the defendant con *180 ceming (a) the nature of the charge, (b) the right to assistance of counsel, (c) the right to confront witnesses against the defendant, (d) the right to a jury trial, and (e) the privilege against self-incrimination; and (2) examine the defendant to determine that he or she understands the foregoing, including, in the absence of an express waiver of such rights by the defendant, whether the defendant understands that by pleading guilty, the defendant waives his or her right to assistance of counsel [due to scrivener’s error, “right to assistance of counsel” should read “privilege against self-incrimination,” as stated supra], right to confront witnesses, and right to a jury trial. Additionally, the record must establish that (1) there is a factual basis for the plea and (2) the defendant knew the range of penalties for the crime with which hе or she is charged.
In
State v. Voight,
In a series of subsequent cases, we interpreted
Smith
as establishing the rule that in DUI enhancement proceedings, a defendant could object to the record of a prior conviction on the basis that it did not affirmatively establish that he or she was represented by counsel or had waived the right to counsel.
State v. Davis,
We addressed this inconsistency in
State v. Oliver,
*182 Upon further consideration of the matter, we now expressly disapprove our holding in the Gonzales case that a defendant may raise the constitutional invalidity of a prior conviction in an enhancement proceeding, and now hold that such an issue may only be raised in a direct appeal or in a separate proceeding commenced for the express purpose of setting aside the judgment alleged to be invalid.
In
State
v.
Crane,
We have repeatedly held that, as a procedural matter, a defendant cannot collaterally attack a prior conviction in an enhancement proceeding and that challenging a prior plea-based conviction based on the lack of a Boykin-type colloquy constitutes a сollateral attack. . . . We do, however, allow challenges to prior plea-based convictions offered for enhancement purposes based on the transcript’s failure to disclose whether the defendant had or waived counsel at the time the pleas were entered. . . . We do so because we do not regard such a challenge as a collateral attack on the former judgment. . . . One could also challenge the constitutional validity of a prior conviction through a separate proceeding, such as an action for declaratory judgment.
Our first occasion to review a collateral attack to a prior plea-based conviction in a separate proceeding was
State
v.
Wiltshire,
*183
Following our decision in
Wiltshire,
the U.S. Supreme Court decided two cases involving the assertion of
Boykin
challenges to plea-based convictions in enhancement proceedings. In
Custis
v.
United States,
Ease of administration also supports the distinction. As revealed in a number of the cases cited in this opinion failure to appoint counsel at all will generally appear from the judgment roll itself, or from an accompanying minute order. But determination of claims of. . . failure to assure that a guilty plea was voluntary, would require sentencing courts to rummage through frequently nonexistent or difficult to obtain state-court transcripts or records that may date from another era, and may come from any one of the 50 States.
The interest in promoting the finality of judgments provides additional suрport for our constitutional conclusion. As we have explained, “[ijnroads on the concept of finality tend to undermine confidence in the integrity of our procedures” and inevitably delay and impair the orderly *184 administration of justice. . . . [Pjrinciples of finality associated with habeas corpus actions apply with at least equal force when a defendant seeks to attack a previous conviction used for sentencing. By challenging the previous conviction, the defendant is asking a district сourt “to deprive [the] [state-court judgment] of [its] normal force and effect in a proceeding that ha[s] an independent purpose other than to overturn the prior judgmen[t].” ... These principles bear extra weight in cases in which the prior convictions, such as one challenged by Custis, are based on guilty pleas, because when a guilty plea is at issue, “the concern with finality served by the limitation on collateral attack has special force.”

In
Nichols
v.
United States,
The impact of
Custis
and
Nichols
upon a defendant’s ability to assert a prior plea-based conviction in a separate proceeding was addressed by the appellate courts of this state in
LeGrand
v.
State,
it is impermissible to attack the validity of a prior conviction in an enhancement proceeding on any grounds, with one exception: We do allow challenges to prior plea-based convictions offered for enhancement purposes based on the transcript’s failure to disclose whether the defendant had or waived counsel at the time the pleas were entered, when the defendant was sentenced to imprisonment for any period of time as a result of the pleas.
LeGrand
v.
State,
On further review, this court determined that the Court of Appeals erred in concluding that
Custis
and
Nichols
invalidated the use of separate proceedings to challenge prior plea-based convictions for purposes of enhancement. Reasoning that “states are free to afford their citizens greater due process protection under their state constitutions than is granted by the federal constitution,”
State
v.
LeGrand,
Thus, there еxists no federal mandate to overrule separate state proceedings to collaterally attack prior state convictions on grounds other than right to counsel or waiver of counsel. A constitutionally invalid conviction used for sentence enhancement works a second constitutional violation on the defendant by allowing an invalid conviction to serve as a predicate for a recidivist conviction. Without separate proceedings, a defendant in a state сase, who is not in custody, has no other forum to challenge a constitutionally infirm judgment sought to be used for sentence enhance *186 ment. With this in mind, we reaffirm our holdings in State v. Oliver, [230 Neb. 864 ,434 N.W.2d 293 (1989)], and State v. Wiltshire, supra, that separate proceedings are a valid means to collaterally attack allegedly constitutionally invalid prior convictions used for sentence enhancement.
State
v.
LeGrand,
Upon further consideration, we now conclude that our holding in
LeGrand
with respect to separate proceedings is unsound for several reasons. We have held that where a criminal procedure is not authorized by statute, it is unavailable to a defendant in a criminal proceeding. See
State v. Miller,
A person who is сonvicted on the basis of a guilty plea has a right to appeal on the ground that the plea was not knowing and voluntary. See
State
v.
Hays,
When the defendant elects
not
to appeal, however, no bill of exceptions is prepared. Under regulations promulgated by the Nebraska Records Management Division, in effect at the time of Louthan’s 1994 conviction and now, the tapes from which the verbatim record ordinarily included in a bill of exceptions could be prepared may be erased 30 days after the appeal time has elapsed. See Records Retention and Distribution Schedule, paragraph 18-10-7 (rev. 1998) and this court’s Rules for Release, Substitution, and Disposal of Exhibits (rev. 1996). Thus, when a separate proceeding is commenced years after a plea-based conviction from which there was no direct appeal, the record will likely not contain any colloquy between the court and the accused at the time of the acceptance of the plea. That is true of the record before us in the present case. While it is impermissible on direct appeal to presume waiver from a silent record, it is illogical and not in the interests of justice to presume from an incomplete record in a separate proceeding that the trial court abrogated its responsibility to ascertain the defendant’s understanding and voluntary waiver of rights before accepting a guilty pleа. Yet that is precisely the position in which the district court in the present case was placed in order to comply with both
State
v.
LeGrand,
Moreover, the “separate proceeding” by which defendants are currently permitted to challenge prior DUI convictions for purposes of enhancement is inconsistent with limitations which our law places upon collateral attack of criminal convictions under other circumstances. For example, subsequent to
LeGrand,
we held that a defendant may not utilize a special proceeding to col
*188
laterally attack a prior conviction that is an element of a subsequent offense.
State
v.
Lee,
We therefore hold that the due process requirements of both the state and federal Constitutions are satisfied by the right of direct appeal from a plea-based DUI conviction and the procedure set forth in § 60-6,196(3), which permits a defendant to challenge the validity of a prior DUI conviction offered for purposes of enhancement on the ground that it was obtained in violation of the defendant’s Sixth Amendment right to counsel. We need not, and therefore do not, reach the issue of whether such a challenge is permissible where the prior conviction did not result in a sentence of imprisonment. See,
Nichols
v.
United States,
CONCLUSION
For the foregoing reasons, we conclude that Louthan’s 1994 DUI conviction was not subject to collateral attack in a separate proceeding and therefore reverse the judgment of the district court and remand the cause with directions to dismiss.
Reversed and remanded with DIRECTIONS TO DISMISS.
