Roger Dale Boykins appeals the denial of his petition for post-conviction relief, by which he sought to set aside his earlier pleas of guilty to theft and burglary. He contends the post-conviction court erred in finding these pleas were entered knowingly, intelligently, and voluntarily.
We reverse.
The state admits that the court accepting Boykins' guilty pleas did not give him the statutory advisements required by IND.CODE 385-4.1-1-8 (now codified at IND.CODE 35-85-1-2 (1982)). Absent these advisements, we must find that Boy-kins did not enter his guilty pleas knowingly, voluntarily, and intelligently. German v. State, (1981) Ind., 428 N.E.2d 234. Thus, the trial court's judgment was contrary to law and must be reversed.
In so holding, we reject the state's suggestion that we remand this matter for a ruling on its affirmative defense of lach-es. The state raised the laches defense in its answer, but the trial court made no findings on this issue in entering its judgment. If the state had presented sufficient evidence at trial to support a finding of laches, the proper disposition would be to remand for specific findings on that issue, as required by Ind.Rules of Procedure, Post-Conviction Rule 1(6). See Salk v. Weinraub, (1979) 271 Ind. 115, 390 N.E.2d 995; Citizens National Bank v. Harvey, (1976) 167 Ind.App. 582, 339 N.E.2d 604. At trial, however, the state presented no evidence that it was prejudiced by Boykins' four-year delay in seeking relief. By introducing no evidence on this crucial element of the laches defense, the state failed to make a prima facie showing of laches. Gregory v. State, (1984) Ind., 463 N.E.2d 464; Morrison v. State, (1984) Ind.App., 466 N.E.2d 783; Mottern v. State, (1984) Ind.App., 466 N.E.2d 488. Thus, a remand for findings on this issue would be futile.
*767Nor do we believe this matter should be remanded for a further evidentiary hearing-in essence a new trial-on the laches defense. We recognize that our recent decision in Ray v. State, (1984) Ind.App., 466 N.E.2d 1389 (Young, J., dissenting), appears to mandate such a result, as does the Second District's decision in Morrison v. State, supra. For several reasons, however, we have reconsidered our decision in Ray. First, we note that the First District of this court, on facts identical to those presented here, has recently held that the proper disposition is not a new evidentiary hearing on laches, but a remand with instructions to vacate the petitioner's guilty plea. Mottern v. State, supra. See also Morrison v. State, supra, (Buchanan, C.J., concurring) (arguing that proper disposition is remand for review limited to merits of petitioner's claim).
Second, and more importantly, we believe our decision in Ray improperly relied on the conclusion that the law governing lach-es was unsettled or "in flux" at the time of the hearing. When this case was tried, the state believed its laches defense was governed by the holding in Stutzman v. State, (1981) Ind.App., 427 N.E.2d 724, that a petitioner for post-conviction relief had the burden of proving his delay was reasonable onee the state had raised the defense of laches. While this appeal was pending, however, our supreme court decided Twyman v. State, (1984) Ind., 459 N.E.2d 705. In Twyman, the court overruled Stutzman and held that the state, not the petitioner, had the burden of proof as to the laches defense.
In so holding, the supreme court gave no indication that it was making new law or deciding a previously unsettled question. Rather, the court based its decision on Ind. Rules of Procedure, Post-Conviection Rule 1(5) and Trial Rule 8(C), as well as the decision in Frazier v. State, (1975) 263 Ind. 614, 335 N.E.2d 623. This authority was, of course, available to the state when this case was tried. Based upon this authority, the supreme court in Twyman held, "The law in Indiana is still that once the State raises the affirmative defense of laches in a post-conviction relief proceeding the petitioner is entitled to an evidentiary hearing upon the issue, before the judge may find laches applies. The burden of proving the defense rests entirely upon the State." 459 N.E.2d at 712 (emphasis added). This holding precludes a finding that the law in this area was unsettled prior to the decision in Twyman and that the state's failure to meet its burden of proving laches was therefore excusable.
Moreover, even if the Twyman decision had changed Indiana law, the state would not necessarily be entitled to a new trial. The decisions in Travelers Indemnity Co. v. Armstrong, (1982) Ind., 442 N.E.2d 349, and cases following it are illustrative. In Travelers, the supreme court announced that claims for punitive damages must henceforth be proved by clear and convine-ing evidence. Applying this new standard to the evidence before it, the court held the evidence was insufficient to support the trial court's award of punitive damages.1 With this holding, the supreme court reversed the trial court's decision even though, at the time of trial, the parties and the trial court justifiably believed the "preponderance of the evidence" standard should be applied. Likewise, in cases following Travelers, our appellate courts have consistently applied the new "clear and convincing evidence" standard retrospectively even where the trial court justifiably applied the old "preponderance" standard. Lloyds of London v. Lock, (1983) Ind.App., 454 N.E.2d 81; Form Bureau Mutual Insurance Co. v. Dercach, (1983) Ind.App., 450 N.E.2d 537; Don Medow Motors, Inc. v. Grauman, (1983) Ind.App., 446 N.E.2d 651.
Under this approach, an award of punitive damages must be reversed without any further hearing where the evidence at trial was insufficient as a matter of law to satisfy the new, higher standard of proof. Don *768Medow Motors, Inc., supra, at 655.2 Thus, a new trial on the issue of punitive damages is appropriate only where it is impossible for the appellate court to determine how the jury would have ruled if the proper standard had been applied. Id. Ordering a new trial in such a case is much like a remand for further findings, where the wrong standard of proof was applied in a trial to the court. See Van Hoosier v. Grant County Dept. of Public Welfare, (1982) Ind.App., 443 N.E.2d 350.
These cases strongly suggest that a new trial on the issue of laches would be inappropriate here. Our supreme court clearly does not view the Twyman decision as having only prospective effect, based as it is upon the Trial Rules and the supreme court's prior decision in Frazier v. State, supra. Thus, like the court in Don Medow Motors and Lloyds of London, supra, we must apply the supreme court's new holding to this case as if Twyman had been decided before the trial court heard Boy-kins' petition. We may not remand for a new trial if the evidence presented at trial was insufficient as a matter of law under Twyman to prove the laches defense. See Don Medow Motors, Inc., supra. As we have already found, the state's evidence at trial was insufficient to meet this standard. Thus, giving the supreme court's Twyman decision retrospective effect in this case, we hold that the state is not entitled to a new trial on the issue of laches.
The trial court's judgment is accordingly reversed, and the cause is remanded with instructions to vacate Boykins' guilty plea.
MILLER, P.J., concurs. CONOVER, J., dissents with opinion.. In so holding, the court noted that the evidence might "conceivably" have been sufficient "under a less stringent standard" to support the punitive damages award. 442 N.E.2d at 363.
. Likewise, where the evidence is "clear and convincing" as a matter of law, an award of punitive damages may be upheld on appeal even though the trial court applied the preponderance standard. See Orkin Exterminating Co. v. Traina, (1984) Ind.App., 461 N.E.2d 693.
