OPINION
BARNES, Judge.Case Summary
Edward Lee Jackson appeals the denial of his petition for post-conviction relief. We affirm.
Issue
We restate the sole issue before us as whether the post-conviction court properly rejected Jackson’s claim that he was not advised of his constitutional rights during a guilty plea hearing conducted in 1979.
Facts
In 1979, the State charged Jackson with one count of Class B felony child molesting and one count of Class C felony child molesting. Later that same year, Jackson agreed to plead guilty to one count of Class D felony child molesting. The trial court sentenced him to two years of incarceration, both suspended, and one year of probation.
In July 2003, Jackson filed a pro se petition for post-conviction relief challeng*122ing his 1979 guilty plea and conviction, which subsequently was amended by counsel. The amended petition alleged that there was not a sufficient record of the 1979 guilty plea hearing to demonstrate that Jackson was advised of his Boykin rights before pleading guilty. The State filed an answer in which, among other things, it asserted the affirmative defense of laches. It later withdrew that defense.
At the hearing on Jackson’s petition, evidence was presented that the tape recording of the 1979 guilty plea hearing could not be located, although the recording of the subsequent sentencing hearing was found. Jackson also testified that he could not remember the guilty plea hearing. Additionally, the 1979 trial judge, prosecutor, and defense attorney all testified or presented affidavits that they could not specifically remember Jackson’s guilty plea hearing. The trial judge and defense attorney, however, did testify to the effect that as a matter of practice defendants who pled guilty in that trial court were adequately advised of their rights. Furthermore, the court reporter present at the 1979 guilty plea hearing had made shorthand notes stating, “constitutional rights—no question about rights.” Tr. p. 14. The chronological case summary also states, “having been advised of his Constitutional rights [Jackson] does now tender plea of guilty to the offense of child molesting. ...” App. p. 2.
On September 8, 2004, the post-conviction court denied Jackson’s petition. It concluded that reconstruction of the record of Jackson’s 1979 guilty plea hearing was possible and that Jackson had failed to establish he was not advised of his Boykin rights at that time. Jackson now appeals.
Analysis
Jackson asserts he definitively established that the official record of his guilty plea hearing was lost and that reconstruction of the record was impossible because no one present could remember details of that hearing. Jackson presents a tenable argument that he was entitled to post-conviction relief in view of the line of cases that had suggested it was proper to vacate a guilty plea if there is ho recording or transcript of the guilty plea hearing and everyone present at the hearing is deceased or unable to remember details- of the particular proceeding. See Corder v. State, 516 N.E.2d 71, 72 (Ind.Ct.App.1987). Because of a recent case from our supreme court disapproving of this approach, and a case from the United States Supreme Court that approved of an approach placing a higher burden on defendants seeking to vacate guilty pleas on collateral review, we determine that Jackson is not entitled to post-conviction relief.
We first consider Boykin v. Alabama, 395 U.S. 238, 89 S.Ct. 1709, 23 L.Ed.2d 274 (1969). In Boykin, a defendant pled guilty to five counts of robbery. Pursuant to Alabama law, a jury subsequently sentenced him to death. On direct appeal from the sentencing decision, the Supreme Court observed that the record failed to reveal that the defendant either was advised of or waived the following three rights when he pled guilty: the privilege against compulsory self-incrimination, the right to trial by jury, and the right to confront one’s accusers. Id. at 243, 89 S.Ct. at 1712. The Supreme Court reversed the convictions and imposition of the death penalty, concluding: “We cannot presume a waiver of these three important federal rights from a silent record.” Id.
In subsequent years, Indiana courts addressed the Boykin holding in situations where the official record of a guilty plea hearing had been misplaced or destroyed. In Zimmerman v. State, 436 N.E.2d 1087 (Ind.1982), our supreme court discussed the consequences of a trial court’s having *123lost the tape recording of a defendant’s guilty plea hearing. Although not specifically mentioning Boykin and the three federal rights that must be knowingly waived by any defendant pleading guilty, our supreme court rejected the argument “that a lost record was per se the equivalent of a silent record.” Id. at 1089. Rather, if no transcript of the hearing can be produced, our supreme court held the defendant must attempt to reconstruct the record by following the provisions of the predecessor to current Indiana Appellate Rule 31, which was Appellate Rule 7.2(A)(3)(c). Id. at 1088-89. The court held that Rule 7.2(A)(3)(c) “abrogated the old practice of ordering a new trial when the transcript of the evidence was unavailable.” Id. The court, however, noted that an exception to this rule “arises when reconstruction of the record is not possible.” Id. at 1089.
Following Zimmerman, it was understood that if a defendant provided sufficient evidence that it was impossible to reconstruct the lost record of a guilty plea hearing, then vacation of the conviction entered pursuant to the plea was required. See Ray v. State, 496 N.E.2d 93, 99 (Ind.Ct.App.1986), trans. denied; Corder, 516 N.E.2d at 72; Patton v. State, 537 N.E2d 513, 515 (Ind.Ct.App.1989). Sometimes, convictions would be upheld despite the loss of a record and the impossibility of reconstructing it if the State sufficiently established the affirmative defense of laches. See Wilburn v. State, 499 N.E.2d 1173, 1175-78 (Ind.Ct.App.1986), trans. denied. Our supreme court cited and discussed Zimmerman in 1996, at which time it said “when a defendant seeks post-conviction relief alleging his guilty plea was not voluntarily made, the loss of a record will require the vacation of the plea and a new trial only when reconstruction of the record through Appellate Rule 7.2 is impossible.” Curry v. State, 674 N.E.2d 160, 162 (Ind.1996). Curry specifically held that the defendant did not meet his burden of proving that reconstruction of his guilty plea hearing was impossible because he “did not establish that all of the persons present at the guilty plea hearing had died or could not remember details of the proceedings.” Id. at 163. Curry in no way indicated that Zimmerman was overruled or no longer valid precedent; in fact, Curry seemed to leave open the possibility that a defendant could be entitled to post-conviction relief from a guilty plea conviction if the record was lost, the defendant established that no one present at the guilty plea hearing was still alive or could remember the specifics of the defendant’s hearing, and the State could not prove laches.
We are now informed that Zimmerman is no longer valid precedent and has not been since 1986. The author of this opinion also authored Graves v. State, 784 N.E.2d 959 (Ind.Ct.App.2003). Our supreme court granted transfer in. that case and recently issued its opinion, in which it essentially asserted that we improperly relied upon Zimmerman as good law because it was overruled by White v. State, 497 N.E.2d 893 (Ind.1986). Graves v. State, 823 N.E.2d 1193, 1194 (Ind., 2005). We are compelled to note that White makes no" mention of Zimmerman throughout the' entire opinion. What White plainly did overrule was German v. State, 428 N.E.2d 234 (Ind.1981). That case concerned the extent of non -Boykin advisements a trial judge must give to a defendant who is pleading guilty and the effect of a failure to give such advisements when the plea is challenged in a post-conviction proceeding—automatic vacation of the guilty plea. German, 428 N.E.2d at 236-37, German did not address the reconstruction of guilty plea hearing records and the effect of being unable to recon*124struct a record.1
We are aware White holds that a post-conviction petitioner seeking relief from a guilty plea-based conviction “needs to plead specific facts from which a finder of fact could conclude by a preponderance of the evidence that the trial judge’s failure to make a full inquiry in accordance with § 35-35-l-2(a) rendered his decision involuntary or unintelligent.” 497 N.E.2d at 905. The very next sentence, however, states, “Of course, unless the record reveals that the defendant knew or was advised at the time of his plea that he was waiving his right to a jury trial, his right of confrontation and his right against self-incrimination, Boykin will require that his conviction be vacated.” Id. It does not appear that White’s holding was intended to apply to Boykin rights.
Our supreme court also states in footnote three of Graves that Zimmerman was implicitly overruled by State v. Scales, 593 N.E.2d 181 (Ind.1992). The express holding of Scales was to reject the State’s argument that Indiana Criminal Rule 10, which requires trial courts to maintain misdemeanor guilty plea records for ten years, created an absolute ten-year statute of limitations for filing post-conviction challenges to a misdemeanor conviction. Id. at 184-85. With respect to “implicit” overrulings generally, it is respectfully observed that they are not reflected in West-law or Lexis citation services. Absent some sort of direct language disapproving of an earlier case, the nuanced nature of an “implicit” overruling makes it difficult to discern the current state of the law.
We also observe that in 1996, our supreme court cited Zimmerman with approval and indicated that it was still valid precedent; in fact, it was cited as controlling authority. Curry, 674 N.E.2d at 162-63. Given our supreme court’s latest word on Zimmerman, Curry is no longer valid precedent, at least to the extent it suggests that the impossibility of recreating a lost guilty plea hearing record requires vacation of the conviction entered pursuant to that plea. We are now writing on a blank slate on this issue. In other words, while Zimmerman and its progeny seemed to create a clear rule as to what must happen if the record of a guilty plea hearing is lost and cannot be reconstructed, that rule no longer exists. There is no clear precedent from our supreme court directly on point with respect to Boykin rights, post-conviction challenges to guilty pleas, and the loss of a guilty plea hearing record. We turn to examine Parke v. Raley, 506 U.S. 20, 113 S.Ct. 517, 121 L.Ed.2d 391 (1992).
Parke analyzed Kentucky’s approach to collateral challenges to guilty plea-based convictions in situations where the record of the guilty plea hearing was lost. The defendant in Parke was charged in 1986 with robbery and was alleged to be an habitual offender because of two burglary guilty pleas entered in 1981 and 1979. Id. at 23, 113 S.Ct. at 520. The defendant had never challenged these convictions until the prosecution initiated the 1986 habitual offender proceedings, but claimed the guilty pleas were invalid under Boykin because no transcripts of the 1981 and 1979 proceedings existed and it could not be shown that the pleas were knowing and voluntary. Id. The trial court rejected the defendant’s challenge to the validity of the 1979 and 1981 convictions, and the Kentucky Court of Appeals affirmed. The *125Kentucky courts relied upon a procedure whereby the prosecution in an habitual offender proceeding was only required to prove the fact of a previous conviction beyond a reasonable doubt; it did not have to prove that the conviction was validly obtained. Id. at 23, 113 S.Ct. at 520. Once the prosecution proved the existence of the judgment, a presumption of regularity attached and the burden shifted to the defendant , to produce evidence that his rights were infringed or some procedural irregularity occurred in the earlier proceeding. Id. at 24, 113 S.Ct. at 520. If the defendant refuted the presumption of regularity, the burden shifted back to the prosecution to show affirmatively that the underlying judgment was entered in a matter that protected the defendant’s constitutional rights. Id. On habeas corpus review, the Sixth Circuit reversed, holding that when no transcript of a prior guilty plea proceeding exists, the prosecution has the entire burden of establishing the plea’s validity and no presumption of regularity can attach to a final judgment. Id. at 25, 113 S.Ct. at 521.
The Supreme Court rejected the Sixth Circuit’s logic and agreed with the Kentucky Court of Appeals. In fact, the Supreme Court stated: “In our view, Kentucky’s burden-shifting rule easily passes constitutional muster.” Id. at 28, 113 S.Ct. at 522. The Supreme Court held that Boykin was inapplicable in this case because “Boykin involved direct review of a conviction allegedly based upon an uninformed guilty plea. Respondent, however, never appealed his earlier convictions. They became final years ago, and he now seeks to revisit the question of their validity in a separate recidivism proceeding.” Id. at 29, 113 S.Ct. at 523. The Supreme Court also stated that it was clear “that even 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. at 31, 113 S.Ct. at 524. Finally, the Supreme Court made the following strongly worded observations regarding long-delayed challenges to guilty pleas:
There is no good reason to suspend the presumption of regularity here. This is not a case in which an extant transcript is suspiciously “silent” on the question whether the defendant waived constitutional rights. Evidently, no transcripts or other records of the earlier plea colloquies exist at all.... The circumstance of a missing or nonexistent record is, we suspect, not atypical, particularly when the prior conviction is several years old. But Boykin colloquies have been required for nearly a quarter century. On collateral review, we think it defies logic to presume from the mere unavailability of a transcript (assuming no allegation that the unavailability is due to governmental misconduct) that the defendant was not advised of his rights. In this situation, 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 validly obtained.
Id. at 30, 113 S.Ct. at 523-24. After Parke, it is clear that if a challenge to a guilty plea can be characterized as a “collateral” attack, then it is appropriate to place the burden of producing evidence of a constitutional violation on the defendant. If the challenge is a “direct” attack, then Boykin applies.
This court addressed Parke late last year in Hall v. State, 819 N.E.2d 102 (Ind.Ct.App.2004). The majority of the Hall panel declined to apply a Parfce-like burden-shifting rule to a situation in which a defendant waited until 2001 to challenge a guilty plea entered into in 1983, and no *126transcript of the guilty plea hearing existed and no other documents indicated that the defendant was advised of his Boykin rights. See id. at 112. Additionally, because none of the parties present could remember details of the defendant’s specific guilty plea hearing, the majority held that reconstruction of the record was impossible and vacation of the 1983 conviction was required. Id. This was so even though, as here, there was evidence presented that the trial judge as a matter of custom always advised defendants of their Boykin rights before accepting a guilty plea. Id.
The majority in Hall declined to follow the Kentucky rule approved of in Parke because in Indiana, post-conviction relief is the only way a defendant can challenge the validity of a guilty plea; the majority concluded, “such petition is not ‘collateral’ in the sense used by the Court in Parke. • It is instead a direct attack on the validity of the underlying conviction with no other independent purpose.” Id. The majority adhered to what it believed to be the valid Zimmerman-based rule, i.e. “a post-conviction petitioner need establish only that the record or transcript of the petitioner’s guilty plea hearings are unavailable and that reconstruction of the record via the Appellate Rules is impossible.” Id. The majority also noted the difference between Parke and the case before it, namely that the defendant in Parke was challenging his prior convictions within the context of a recidivist sentence enhancement proceeding while Hall had filed a purportedly freestanding post-conviction relief , petition. Id. at 108.
Judge May, a member of the current panel, dissented in Hall and advocated for the burden-shifting rule analyzed in Parke. With respect to the difference in procedural posture between Parke and Hall, she observed that defendants in Indiana cannot raise a Boykin challenge to a previous conviction directly during habitual offender proceedings, and so the Parke situation can never arise precisely in Indiana. Id. at 113 (May, J., dissenting) (citing Edwards v. State, 479 N.E.2d 541, 547-48 (Ind.1985)). She went on to state:
I find it inconceivable that Hall filed his petition for post-conviction relief without an “independent purpose” other than to overturn the prior conviction, because Hall is no longer suffering any direct consequences of his plea. He filed his petition for post-conviction relief eighteen and a half years after being given “a five-year suspended sentence with two years on probation.” Any complaint he has now is undoubtedly based on his desire to avoid some indirect negative consequence—be that an habitual offender proceeding, difficulty getting a job because of his criminal record, or inability to vote.
Id. at 114 (internal citations omitted). Our supreme court recently granted transfer in Hall. This does not necessarily mean that it disagrees with the Hall majority. Nevertheless, two of the panel members in this case believe that the dissenting opinion in Hall embodies the correct view.
The position of the Hall majority essentially is that because a post-conviction relief proceeding is the only way in which a defendant in Indiana may challenge the validity of a guilty plea, such an attack is always “direct” for Boykin purposes and never “collateral” for Parke purposes. Thus, Boykin and its “direct” appeal requirement that the record must affirmatively show the waiver of the right to jury trial, right to confront witnesses, and the privilege against self-incrimination, would always apply. The Hall majority placed much emphasis on the definition of “collateral attack” provided in Parke, which is an effort to deprive previous convictions of *127their normal force and effect in a proceeding that has an independent purpose other than to overturn the prior judgments. Hall, 819 N.E.2d at 108 (citing Parke, 506 U.S. at 30, 113 S.Ct. at 523).2 The only purpose of a post-conviction challenge to a guilty plea, the Hall majority asserted, is to overturn the prior judgment.
We agree that in one sense, especially with respect to guilty pleas, post-conviction relief petitions allow a “direct attack” on a conviction because the only facial purpose of such a petition is to set aside a prior judgment. On the other hand, it is axiomatic that a post-conviction relief proceeding is a quasi-civil one that is completely separate and distinct from the underlying criminal proceeding. See Phillips v. State, 441 N.E.2d 201, 203 (Ind.1982). Also, the courts of this State have repeatedly labeled post-conviction proceedings as “collateral” in nature. See, e.g., Lambert v. State, 743 N.E.2d 719, 725 (Ind.2001). It thus appears to us that a post-conviction relief petition could be construed either as a “direct” or “collateral” attack on a conviction, depending on the circumstances. We think it is necessary to focus narrowly on whether Jackson’s post-conviction petition may be construed as a “collateral” attack strictly for purposes of Parke’s burden-shifting rule, based on the particular facts and circumstances of his case, regardless of whether the petition might be a “direct” attack for other purposes. After reading Parke in its entirety, we conclude the Supreme Court readily would approve of placing the burden of producing evidence of a Boykin violation on a defendant such as Jackson because he effectively launched a “collateral” attack on his 1979 guilty plea.
Parke clearly permits making it difficult for defendants who have pled guilty to challenge their plea many years later. It also disapproved of allowing defendants to avoid the consequences of their plea simply because the official record of their plea hearing has disappeared through no one’s fault. In our view, Parke stands for the proposition that there is no constitutional right that decades-old tape recordings of guilty plea hearings never be lost, nor that trial judges and attorneys have perfect memories regarding long-ago proceedings. We see no indication that the Supreme Court intended to narrowly limit this proposition only to challenges to guilty pleas that arise within the official context of an habitual offender proceeding. Of course, Parke did not mandate that the states implement rules that place the burden of proving constitutional infirmity on defendants who challenge their guilty pleas in a collateral setting. ■ It merely approved such rules. We conclude, however, that such a rule would be consistent with Indiana case law and- our post-conviction rules.
We mentioned White v. State earlier in this opinion. There, our supreme court expressed great consternation with prisoners who had pled guilty being able to successfully challenge their guilty pleas many years after the fact. The court stated:
Routine reversal of convictions on technical grounds imposes substantial costs on society.... Jurors, witnesses, judges, lawyers, and prosecutors may be required to commit further time and other resources to repeat a trial which has already taken place. The victims are caused to re-live frequently painful expe*128riences in open court. The erosion of memory and the dispersal of witnesses may well make a new trial difficult or even impossible. If the latter is the case, an admitted perpetrator will be rewarded with freedom from prosecution. Such results prejudice society’s interest in the prompt administration of justice, reduce the deterrent value of any punishment, and hamper the rehabilitation of wrongdoers.
White, 497 N.E.2d at 905. This was the reason the White court held that merely demonstrating a trial court’s failure to give all of the advisements required by Indiana Code Section 35—35—1—2(a) is not enough to warrant post-conviction relief from a guilty plea. Instead, the petitioner must allege and prove by a preponderance of the evidence that such failure rendered the plea decision involuntary or unintelligent. Id. In the recent Graves decision, the court again plainly evidenced its skepticism toward post-conviction challenges to ancient guilty pleas. See Graves, at 963. We also observe that the White court labeled post-conviction relief challenges to guilty pleas as “collateral attacks on criminal convictions .... ” 497 N.E.2d at 905.
We do agree with the Hall majority to the extent that there might be occasions when a post-conviction challenge to a guilty plea should be considered a “direct attack” and the rule of Boykin rather than Parke should apply. We do not need to identify any such situations today. We do hold that in a situation such as that before us today, in which a defendant is no longer suffering any direct negative effects of his or her guilty plea because any sentence and probationary period stemming from the plea has been fully served, a post-conviction challenge to such a plea should be deemed “collateral” for purposes of Parke. On such “collateral” review it should be presumed that a judgment was entered validly, regardless of whether the official record of a proceeding is lost, and a defendant should bear the burden of forwarding evidence of invalidity or a constitutional violation. If such evidence is forwarded, then the State must present evidence to the contrary, but it is still an inherently factual question to be resolved by the post-conviction court as to whether the violation occurred. This approach is consistent with the plain language of our post-conviction rules, which provide that a petitioner “has the burden of establishing his grounds for relief by a preponderance of the evidence.” Ind. PosWConviction Rule 1(5). This is also consistent with the Supreme Court’s and our supreme court’s stated skepticism regarding long-delayed challenges to guilty pleas. Otherwise, and perversely, the finality of a guilty plea would decrease rather than increase as time marches on, as judges, lawyers, and reporters die or forget the details of proceedings, tape recordings become misplaced or disintegrate in crowded courthouse vaults, and the possibility of definitively proving that Boykin advisements were given to a particular defendant fades into oblivion. Parties should not be permitted to “game” the system in such a manner.3
We also observe that the affirmative defense of laches is not by itself sufficient to preserve the integrity of final judgments in all cases. “For laches to *129apply, the State must prove by a preponderance of the evidence that the petitioner unreasonably delayed in seeking relief and that the State is prejudiced by the delay.” Armstrong v. State, 747 N.E.2d 1119, 1120 (Ind.2001). Prejudice exists when the .unreasonable delay operates to materially diminish a reasonable likelihood of successful re-prosecution. Id. Here, the State initially pled laches in response to Jackson’s post-conviction relief petition. Later, after interviewing witnesses to the 1979 molestation, the State withdrew the defense because the witnesses could still recall and testify about the event. The State, therefore, could not establish the prejudice element of laches. Still, those witnesses, and especially the victim of the 1979 crime, certainly were entitled to expect that Jackson’s guilty plea over twenty-five years ago had concluded the matter. They should not have to relive the event in a new trial, in the absence of clear evidence that the plea was entered in violation of Jackson’s constitutional rights. Society at large also has an interest in ensuring the finality of convictions, and upholding the integrity of the criminal justice system.
Here, Jackson pled guilty in 1979 to a Class D felony, for which he received a two-year suspended sentence and one year of probation. He did not file his petition for post-conviction relief until 2003.4 Parke should apply here, and the mere fact that the transcript of his plea hearing is missing and no one present ,at the hearing can remember details of it does not warrant relief from the 1979 plea. Instead, the validity of the plea is presumed. Jackson was required to present some evidence that the Boykin advisements were not given in this case. He did not do so; the inability of Jackson, the trial judge, prosecutor, and defense attorney to remember what precisely was said at one plea hearing conducted decades ago was not enough. In any event, the State presented ample evidence that it would have been highly unusual for Boykin advise-ments not to be given such that any testimony to the contrary could be rebutted. The post-conviction court properly denied Jackson’s petition. .
Conclusion
We adopt and apply to this case the burden-shifting approach to post-conviction Boykin challenges to old guilty pleas approved of by Parke. We are confident our supreme court would approve of such an approach, particularly given that Zimmerman has now clearly been overruled. The validity of Jackson’s 1979 guilty plea is presumed. The loss of the record of the guilty plea hearing and the loss of memory regarding what was said at the hearing is not sufficient to overcome this presumption. We affirm the denial of post-conviction relief.
Affirmed.
MAY, J., concurs. D ANDEN, J., dissents with separate opinion.. The White court stated that in deciding whether a plea was made voluntarily and intelligently, courts must review all of the evidence, including "the transcript of the petitioner's original sentencing...." 497 N.E.2d at 905. Zimmerman specifically addressed what to do if there is no such transcript.
. Our supreme court has similarly defined "collateral attack” as "an attack made in a proceeding that has an independent purpose other than to impeach or overturn the judgment, although impeaching or overturning the judgment may be necessary to the success of the action.” Indiana Dep't of Envtl. Mgmt. v. Conard, 614 N.E.2d 916, 922 (Ind.1993).
. The Hall majority noted that our supreme court decided Curry well after Parke was decided and it could have addressed Parke in that opinion. Hall, 819 N.E.2d at 108. The fact that it did not should not be seen as having any substantial legal significance. Courts make their decisions on the basis of arguments advanced to them by the parties. We presume that if the State in briefing Curry had asked our supreme court to apply Parke, the court would have discussed or at least mentioned it.
. There was no evidence presented below as to why Jackson waited over two decades to challenge his 1979 guilty plea. We surmise that Jackson is the same Edward Lee Jackson whose 1998 conviction and sentence for child molesting were affirmed by our supreme court in Jackson v. State, 735 N.E.2d 1146 (Ind.2000). The sentence he received in that . case was the maximum fifty years for a Class A felony, plus a thirty-year habitual offender enhancement. Although not affecting our analysis in this case, this likely explains why the 1979 plea was not challenged until 2003. Unlike in Kentucky, Jackson could not directly challenge his 1979 plea on Boykin grounds during the 1998 habitual offender proceeding. See Edwards, 479 N.E.2d at 547-48.
