PEOPLE of the State of Illinois, Plaintiff-Appellee,
v.
David REED, Defendant-Appellant.
No. 3-97-1018.
Appellate Court of Illinois, Third District.
January 29, 1999.
*1060 Verlin R. Meinz (argued), Office of the State Appellate Defender, Ottawa, for David Reed.
John X. Breslin, Deputy Director, Michael James, State's Attorney, Robert M. Hansen (argued), State's Attorneys Appellate Prosecutor, Ottawa, for the People.
Presiding Justice HOLDRIDGE delivered the opinion of the court:
The defendant, David Reed, pled guilty to the offense of armed robbery and was sentenced to a term of 15 years imprisonment. The plea of guilty was entered and sentence was imposed by judgment entered on March 17, 1994. No post-plea motion or appeal was filed. On February 27, 1997, the defendant filed a post-conviction petition pursuant to the Post-Conviction Hearing Act (the Act) (725 ILCS 5/122-1 et seq. (West 1997)). The defendant maintained in his petition that he had been taking psychotropic medication at the time he entered his guilty plea and his attorney had been ineffective in not requesting that the court order a fitness hearing prior to accepting the guilty plea. The trial court dismissed the defendant's petition as untimely, holding that the defendant had only 7 months from the entry of the judgment of conviction in which to file his post-conviction petition. We reverse and remand for further proceedings.
Dismissal of a post-conviction petition without an evidentiary hearing is subject to de novo review. People v. Coleman, 183 Ill.2d 366, 233 Ill.Dec. 789, 701 N.E.2d 1063 (1998). Here, our task is to interpret the statute of limitations provided by the Act:
"(c) No proceedings under this Article shall be commenced more than 6 months after the denial of a petition for leave to appeal or the date for filing such a petition if none is filed or more than 45 days after the defendant files his or her brief in the appeal of the sentence before the Illinois Supreme Court (or more than 45 days after the deadline for the filing of the defendant's brief with the Illinois Supreme Court if no brief is filed) or 3 years from the date of conviction whichever is sooner, unless the petitioner alleges facts showing that the delay was not due to his or her culpable negligence." 725 ILCS 5/122-1(c) (West 1997) (effective January 1, 1997).
Thus, the Act ties the timing of the post-conviction petition to one of three specific events: (1) the filing or possible filing of a petition for leave to appeal (PLA); (2) the filing of a brief in appeal of the sentence to our supreme court, or (3) the date of conviction. The Act specifies different time periods as to each reference pointwithin 6 months from the denial of a petition for leave to appeal (or the due date of such a petition if one is not filed), within 45 days from the filing of the defendant's brief where the appeal is taken by our supreme court (or the due date of the brief if none is actually filed), or 3 years from the defendant's conviction. The Act further provides that the shortest time period, the earliest date, be used.
The issue raised by this appeal is which of the three limitations specified by the Act should apply where no appeal is taken of the underlying conviction. This is a matter of first impression with our courts. Two possible alternatives are offered for our consideration. The People maintain that, although no actual due date for a PLA could exist in situations where no appeal is taken, a due date for the filing of a PLA could be presumed to exist on a date 30 days after the defendant could have appealed the underlying conviction. Thus, the People maintain, the Act's limitation on filing post-conviction petitions within 6 months of the due date of a PLA would be the appropriate deadline. In contrast, the defendant herein maintains that *1061 the limitation ending three years after the conviction is applicable.
We agree with the defendant and hold that where no appeal is taken of the underlying conviction, the defendant's post-conviction petition must be filed within 3 years of the entry of the judgment of conviction, unless he or she alleges facts showing that the delay was not due to his or her culpable negligence. We find no support in the Act or elsewhere for the People's assertion that the legislature intended a presumptive due date for a theoretical PLA in drafting the Act. To the contrary, the due date for a PLA is a date certain that can only be determined in a manner specified in Supreme Court Rule 315(b) (___ Ill.2d ___), which requires as a prerequisite to the filing of a PLA the existence of a "judgment of the Appellate Court." Thus, the due date for the filing of a PLA is triggered only by a decision of the appellate court. Where there is no appeal to the appellate court, there can be no decision of that court from which to seek our supreme court's leave to appeal. As there can be no petition to our supreme court in such cases, there can be no "due date" for such a non-existent event.
Further, we note that interpreting the Act as we have in this matter, recognizes a certain logical relationship among the three time limitation periods provided in the Act. The 6 month limitation applies when there has been an appeal to the appellate court, which triggers "a denial of a [PLA] or the date for filing such." The 45 day period applies to cases going directly to our supreme court (e.g. a capital case) or in cases where a PLA is granted. Finally, the provision limiting post-conviction petitions to within 3 year of the date of conviction applies all other cases, i.e., such as the instant matter where no appeal was taken.[1] Thus, each possible post-conviction avenue of appeal (including the decision not to appeal) is provided for under the Act with its own discrete and specific time limit for post-conviction petition.
In so holding, we cannot accept the People's assertion that it is illogical or absurd for the legislature to ascribe the longest time for post-conviction appeal to the defendant who chooses to forego the avenue of a direct appeal. The People ask this court to speculate, as did the trial court, that our legislature would not countenance the longest period of time in which to file a post-conviction petition for a defendant who "sat around and did nothing" i.e. did not file an appeal of his or her conviction. Although pure speculation as to the intent of our legislature is of dubious value, were we to engage in such speculation, we would have to agree with the defendant's assertions that it is equally likely that the legislature intended the longer limitation period for defendants who had not appealed their conviction. In so doing, the legislature may have been recognizing that, by not pursuing a direct appeal, the defendant waived all statutory, sentencing or credit issues cognizable only on direct appeal, and thus he or she should have a longer period in which to pursue the very limited remedy available under the Act.
Finally, we note that the trial court, after ruling that the defendant's post-conviction petition was untimely, also gave its "advisory" opinion that the petition lacked merit. Although each party asks this court to either affirm or reverse the trial court's "advisory" ruling, we must decline the invitation, as neither the trial court nor this court are empowered to render advisory opinions. People v. Halasz, 244 Ill.App.3d 284, 285-86, 185 Ill.Dec. 177, 614 N.E.2d 311 (1993).
For the foregoing reasons, we find that the defendant's post-conviction petition was timely. We reverse the order of the circuit court of LaSalle County and remand this matter for further proceedings consistent with this decision.
Reversed and remanded.
LYTTON and KOEHLER, JJ., concurred.
NOTES
[1]  It would appear that the "3 years from the date of conviction" period may be involved even in the event of a direct appeal if, for example, the direct appeal and PLA process were to extend beyond 3 years from the date of conviction. However, as that specific question is not germane to the matter sub judice we leave that question to a future court.
