ORIGINAL PROCEEDING IN PROHIBITION
LAURA DENVIR STITH, Judge.This case comes to the Court following a trial in which the jury found Relator, Barry Baker, guilty of first-degree murder but was unable to agree on punishment. Respondent ordered a new penalty-phase trial only, believing such a retrial was permitted and required by this Court’s decision in State v. Whitfield, 107 S.W.3d 253 (Mo. banc 2003), decided after trial but before Respondent had ruled on Relator’s post-trial motions and before sentencing. Relator filed a petition for writ of prohibition in this Court. This Court issued its preliminary writ, which is now made absolute.
Respondent’s attempt to grant Relator’s motion for new trial came after the motion had been denied automatically under Rule 29.11(g) and was of no effect. Because this case was tried after the United States Supreme Court decided Ring v. Arizona, 536 U.S. 584, 122 S.Ct. 2428, 153 L.Ed.2d 556 (2002), the principles set out in Ring must be applied to it. As stated in Whitfield, this means that, where, as here, the jury was unable to agree on punishment and the record fails to show that the jury found all facts necessary to impose a sentence of death, the trial court’s only authority was to enter a sentence of life imprisonment without possibility of probation or parole.
*492 I. PROCED URAL HISTORY AND AUTHORITY TO GRANT MOTION FOR NEW TRIAL
A. Trial Proceedings.
Barry Baker was found guilty by a jury of the first-degree murder of Trisha Blue. Because the State was seeking the death penalty, a penalty-phase trial was then held, during which the parties presented evidence concerning whether Mr. Baker should be sentenced to death or to life in prison without possibility of probation or parole. Section 565.030.4 sets out the steps the jury must follow if it is to render a verdict of death.1
On March 24, 2003, the jury in Mr. Baker’s case returned a verdict stating that it had unanimously found the presence of four statutory aggravating factors beyond a reasonable doubt but that the jurors were “unable to decide or agree upon the punishment.” The record, however, fails to show that the jury completed the other steps necessary to impose a death sentence, including considering whether mitigating circumstances outweighed those in aggravation, before becoming deadlocked, as required by Ring, Whitfield, and section 565.030.4(3), RSMo Supp.2003. Because the jury was unable to reach a decision on punishment, Respondent discharged the jury.
B. Rulings on PosNTñal Motions.
Under Rule 29.11(b), a defendant has 15 days in which to file a motion for new trial, but the trial court can grant up to 10 additional days in which to file the motion. The court did so here, making the motion due on or before April 18, 2003. On April 16, 2003, Mr. Baker timely filed his motion alleging various trial errors and asking Respondent alternatively to enter an acquittal, to enter a sentence of life imprisonment, to. grant him a new trial, or to grant him a new penalty-phase trial.
Under Rule 29.11(g), “[i]f the motion for new trial is not passed on within ninety days after the motion is filed, it is denied for all purposes.” In this case, the 90 days for ruling on Mr. Baker’s motion for new trial ended on July 15, 2003. On May 19, 2003, Respondent set the motion for new trial for hearing on June 12, 2003, and scheduled sentencing for June 19, 2003. But, Respondent did not rule on Relator’s motion on that date or any other. Instead, when this Court decided State v. Whitfield, 107 S.W.3d 253 (Mo. banc 2003), on June 17, 2003, Mr. Baker filed what he labeled as a “supplemental” motion in which he asserted that the court was required by *493Whitfield, to enter a sentence of life in prison without the possibility of probation or parole. Two days later, on June 19, 2003, Mr. Baker filed an amended supplemental motion asking the court for the same relief. Rather than rule on the pending motion for new trial filed on April 16, 2003, Respondent then gave the parties until August 1, 2003, to file supplemental briefing addressing how Whitfield might apply to Mr. Baker. During the course of this briefing, the July 15, 2003, deadline for ruling on defendant’s April 16 motion for new trial passed, and that motion was overruled by operation of Rule 29.11(g).
Respondent heard arguments about Whitfield on August 13, 2003. On September 11, 2003, he entered a judgment that did not mention the April 16, 2003, motion for new trial. Instead, he took up and purported to grant Mr. Baker’s June 17 and June 19 motions, but did so by granting Mr. Baker a new trial, even though those motions asked only for entry of a life sentence based on Whitfield. In any event, the “supplemental” motions did not extend the July 15, 2003, deadline as they were filed after the time the motion for new trial was required to be filed. Supplemental motions filed after the time the motion for new trial is due are a nullity. State v. Mucie, 448 S.W.2d 879, 890 (Mo.1970). The trial court had no authority to act on any motion for new trial or supplement after July 15, 2003. Mr. Baker then filed his petition in this Court, asking the Court to prohibit Respondent from holding a new trial.
II. ANALYSIS
Respondent argues that his entry of an order for a new trial on September 11, 2003, was within his authority because the jury did not return a penalty-phase verdict and, thus, Rule 29.13(b) is inapplicable. Rule 29.13(b) states: “The court may, with the consent of the defendant, order a new trial of its own initiative before the entry of judgment and imposition of sentence but not later than thirty days after the verdict of the jury is returned.” Rule 29.13(b).
This Court disagrees. The jury returned a verdict form stating that it was unable to agree upon punishment. While the parties disagree as to whether this constitutes a “verdict” as that term is used in Rule 29.13(b), just quoted, under either interpretation of the term “verdict,” Rule 29.13(b) provided no basis for Respondent to order a new trial. For, if the jury’s return of the form, which was labeled “Verdict,” constituted its verdict under Rule 29.13(b), then Respondent had only 30 days thereafter in which to order a new trial sua sponte. It is undisputed that Respondent did not do so. If the form the jury returned is not considered a “verdict,” then Rule 29.13(b) simply is not applicable. And, in any event, by the time Respondent ruled, defendant had made it very clear that he did not consent to a new trial.
But, Respondent argues, this Court’s decision in Whitfield itself provided the “trigger” or authority for granting a new trial. Respondent so concluded because he believed that, while Whitfield prohibited him from entering a judgment of death, it did not mandate entry of a life sentence where the jury did not agree on punishment except in the five cases that Whitfield noted were on collateral review at the time of its decision. See Whitfield, 107 S.W.3d at 269 n. 17. Because he had not yet entered a sentence of life or death, and because Mr. Baker’s case was not on collateral review and so was not one of the eases listed in Whitfield, Respondent believed he had the authority to order a new penalty-phase trial and did so. If he had no authority to order this new penalty-phase trial, he argues, it is the equivalent of saying he had *494no authority to comply with the requirements of Whitfield even though it is the relevant governing case.
Respondent’s options were not so limited. First, as noted, nearly 30 days yet remained in which he could have ruled on Relator’s motion for new trial after W.hit-field was decided. While the Court appreciates Respondent’s desire to have full briefing on that case’s potential application before ruling, nothing in that decision or in relevant case law provides that the decision of a governing case during the pen-dancy of a motion for new trial will start the running of a new 90-day period or otherwise authorizes the trial judge to act outside the time periods set out in Rules 29.11(g) and 29.13(b). The trial court acted in excess of its jurisdiction in granting a new trial once the time periods for doing so had lapsed.
Second, Respondent could comply with Whitfield by granting the relief requested by Mr. Baker — sentencing him to life in prison. There was no time constraint on his so doing after Whitfield was decided.
Respondent alternatively argues that Whitfield does not apply to Mr. Baker. In so construing Whitfield, Respondent relies solely on those portions of Whitfield addressing whether Whitfield will apply to cases on collateral review. This Court noted that on preliminary review of its records there appeared to be only five such cases on collateral review when Ring was decided.2 But, Ring was decided on June 24, 2002, while this case was still pending in the trial court — indeed, long before it was even tried.
Whitfield was very specific that it applied to cases that were pending at the time that Ring was decided. In fact, it noted, id. at 268, that Ring had to be applied to pending cases under Griffith v. Kentucky, 479 U.S. 314, 107 S.Ct. 708, 93 L.Ed.2d 649 (1987), in which the Supreme Court held that a new rule for the conduct for criminal prosecutions must be “applied retroactively to all cases, state or federal, pending on direct review or not yet final.” Griffith, 479 U.S. at 328, 107 S.Ct. 708.
This did not assist Mr. Whitfield, for his “appeal was not pending on direct review [when Ring was decided].” Whitfield, 107 S.W.3d at 265-66. By contrast, the instant case was pending in the trial court, and was not yet final, when Ring was decided in 2002, and, for that matter, when Whitfield was decided in June 2003. Thus, Ring fully applies to it, and, as Whitfield expressly held, “under Griffith, Ring must be applied to all future death penalty cases and to those not yet final or still on direct appeal.” Whitfield, 107 S.W.3d at 268.
As Respondent acknowledges, if Whitfield is applicable, then where, as here, the jury was unable to reach agreement on punishment and the verdict that was returned did not show that the jury found all facts necessary for the imposition of death, Respondent’s only option was to impose a sentence of life. Id. at 270.
*495For these reasons, the writ is made absolute.3
WHITE, C.J., WOLFF and TEITELMAN, JJ., concur. PRICE, J., concurs in separate opinion filed. LIMBAUGH, J., dissents in separate opinion filed. BENTON, J., concurs in opinion of LIMBAUGH, J.. The pertinent portion of section 565.030.4 provides:
The trier shall assess and declare the punishment at life imprisonment without eligibility for probation, parole, or release except by act of the governor:
(1) If the trier finds by a preponderance of the evidence that the defendant is mentally retarded; or
(2) If the trier does not find beyond a reasonable doubt at least one of the statutory aggravating circumstances set out in subsection 2 of section 565.032; or
(3) If the trier concludes that there is evidence in mitigation of punishment, including but not limited to evidence supporting the statutory mitigating circumstances listed in subsection 3 of section 565.032, which is sufficient to outweigh the evidence in aggravation of punishment found by the trier; or
(4)If the trier decides under all of the circumstances not to assess and declare the punishment at death. If the trier is a jury it shall be so instructed.
RSMo Supp.2003. This version of the statute differs from that discussed in Whitfield, 107 S.W.3d at 258-59. A new step 1 is added to address situations in which the defendant is found to be mentally retarded, and step 2 in Whitfield is eliminated. Step 1 in Whitfield is step 2 now. Steps 3 and 4 in the new statute are the same as in Whitfield.
. Whitfield, 107 S.W.3d at 268-69 ("Thus, only those few Missouri death penalty cases that are no longer on direct appeal and in which the jury was unable to reach a verdict and the judge made the required factual determinations and imposed the death penalty will be affected by the retroactive application of Ring ... to cases on collateral review”). This comment did not purport to deny review if, on further review, it was determined that Whitfield also applied to a limited number of additional cases on collateral review that were not then brought to the Court’s attention, and, to the extent that isolated sentences could be so interpreted, they must be read in the context, and the entire discussion read in light of the additional holding that Griffith requires Ring to be applied to all cases then pending or not yet final.
. The Court thanks counsel for their excellent presentations of the arguments on both sides of the issues in this appeal.
