delivered the Opinion of the Court.
{1 We granted the People's petition for writ of certiorari to review the court of appeals' opinion in People v. Griffin, - P.3d ---, --,
12 Griffin's counsel argues that the doctrine of abatement ab initio applies here because Griffin died while his case was pending on direct appellate review of his conviction. Thus, Griffin asks us to dismiss the appeal, vacate the judgment of the court of appeals, and remand with directions to return the case to the district court to dismiss the complaint. The People argue that we should resolve the appeal despite Griffin's death because the State has an interest in obtaining resolution of the court of appeals' interpretation of the sex offender registration laws and this issue is likely to evade future review. The People also note that other courts have questioned the continuing validity of the abatement ab initio doctrine in light of other interests, including the rights of crime vie-tims.
3 Consistent with cases from the United States Supreme Court and other jurisdictions, we decline to apply the doctrine of abatement ab initio to matters pending on certiorari review. In light of Griffin's death, we vacate our order granting the writ of certiorari and dismiss the People's petition, but do not abate the proceedings ab initio.
Discussion
¶ 4 The doctrine of abatement ab initio is not grounded in the constitution or in statute, but is instead a court-created common law doctrine. United States v. Estate of Parsons,
15 Courts have articulated two primary rationales for the abatement ab initio doe-trine. The first rationale rests on the notion that "an appeal is an integral part of our system of adjudicating guilt or innocence and defendants who die before the conclusion of their appellate review have not obtained a final adjudication of guilt or innocence." People v. Valdez,
'I 6 The second rationale is related to mootness concerns. This rationale assumes that the primary purpose of the criminal justice system is to punish offenders, and that the death of the defendant renders enforcement of the punishment impossible. Estate of Parsons,
1 7 This court first recognized the doctrine over 100 years ago in Overland Cotton Mill Co. v. People,
18 Fifty years later, we briefly addressed the doctrine in Crowley v. People,
T 9 Courts generally have limited the applicability of the doctrine to cases pending on direct appeal (Le., a first appeal as of right), and have not extended the doctrine to cases on certiorari review. For example, in Dove v. United States,
1 10 The United States Supreme Court has also declined to apply the doctrine in cases where a defendant dies after the appellate court has granted certiorari review. On numerous such occasions, the United States Supreme Court has simply dismissed the case without abating the proceedings ab ini-tio. See, e.g., Mosley v. United States,
In most eriminal cases, proceedings in the Supreme Court differ from those in the Courts of Appeals in one fundamental respect: appeals to the Courts of Appeals are of right, but writs of certiorari are granted at the discretion of the Supreme Court. The prevailing practice of the Supreme Court to dismiss petitions for cer-tiorari upon the death of the convicted defendant, therefore, does not readily transfer to the Courts of Appeals.
1 11 Several state courts have also declined to extend the doctrine to cases in which a defendant dies while the case is pending further discretionary review
112 This court has never directly addressed in a published opinion whether the doctrine of abatement ab initio applies where a defendant dies while his case is pending on certiorari review. However, at least two opinions of the court of appeals have indicated that it does not. In Valdez, the court of appeals declined to apply the doctrine in the post-conviction context, where the defendant died while his case was on appeal from the trial court's denial of his Crim. P. 85(c) motion.
1 13 Although we have summarily ordered that a deceased defendant's convictions be vacated ab initio where the defendant died after we granted certiorari review of his convictions, see People v. Versteeq, - P.3d ---, --,
114 We now hold that, consistent with the practice of the United States Su
115 Here, Griffin died while his case was pending on discretionary certiorari review.
Notes
. We granted certiorari review to address the following issues:
1. Whether physical presence or occupancy is required to establish a residence under the Colorado Sex Offender Registration Act.
2. Whether the court of appeals erred in finding that the evidence was insufficient to support the defendant's conviction for the continuing offense of failure to register as a sex offender.
. Specifically, we asked the parties to address the following questions:
1. Whether the proper resolution of a certiorari review of a conviction reversed on direct appeal is abatement ab initio when the defendant has died during the pendency of such review.
2. In any event, whether the issues accepted for review in this case are of sufficient public importance and may evade future review such that resolution by the court is warranted despite the defendant's death.
. Overland involved a direct appeal from the County Court, City and County of Denver.
. We recognize that a few state courts have applied the abatement ab initio doctrine where a defendant dies after the court has granted certio-rari review. See, e.g., People v. Mazzone,
. We note that this case is unusual-unlike nearly all cases in which the abatement ab initio doctrine is discussed, the defendant here was not seeking further discretionary review of his conviction. Assuming that abatement ab initio aims to protect a defendant's opportunity to obtain a final adjudication of guilt or innocence, application of the doctrine would serve no purpose here, given that Griffin won his appeal below and his conviction was vacated.
