OPINION

JOHNSON, Judge.

In 2007, Lane Francis Weitzel pleaded guilty to one count of failure to register as a predatory offender. In 2014, he filed a petition for postconviction relief in which he seeks to withdraw his guilty plea on the ground that it is inaccurate because it lacks an adequate factual basis. In its answer to the petition, the state opposed postconviction relief on the merits, without addressing whether the petition is timely. The postconviction court nonetheless denied the petition on the grounds that it is untimely and that Weitzel did not satisfy the interests-of-justice exception to the statute of limitations. On appeal, Weitzel argues that the district court erred by denying the petition for untimeliness because the state waived the defense of untimeliness by failing to raise it in its answer to the petition. We conclude that the district court did not abuse its discretion by denying the petition as untimely because Weitzel had an opportunity to present argument concerning the applicability of the interests-of-justice exception to the two-year statute of limitations and actually presented such an argument. Therefore, we affirm.

FACTS

In May 2006, police in the city of Ramsey received a report that Weitzel was residing in the city without complying with his duty to register as a predatory offender. In September 2006, the state charged Weitzel with one count of failure to register as a predatory offender. See Minn. Stat. § 243.166, subd. 5 (2006). In June 2007, Weitzel pleaded guilty. The district court imposed a sentence of 17 months of imprisonment but stayed execution of the sentence and placed him on probation for five years. Weitzel did not pursue a direct appeal.

In March 2014, Weitzel petitioned for postconviction relief. See Minn.Stat. § 590.01, subd. 1(1) (2012). In his petition, he seeks to withdraw his guilty plea on the ground that the plea is invalid because it lacks an adequate factual basis. See Munger v. State, 749 N.W.2d 335, 337-38 (Minn.2008); State v. Theis, 742 N.W.2d 643, 646 (Minn.2007); State v. Ecker, 524 N.W.2d 712, 716 (Minn.1994). At his plea hearing in 2007, Weitzel stated that he did not inform his local law-enforcement agency or the Bureau of Criminal Apprehension of his new residence in Ramsey, though he did inform his corrections officer. In a 17-page memorandum in support of the postconviction petition, Weitzel argued that he satisfied the applicable registration requirements by informing his corrections officer of his new residence and, thus, did not commit a crime. See Minn.Stat. § 243.166, subd. 3(b). In his memorandum, he also argued that his guilty plea is invalid because he received ineffective assistance of counsel. In his postconviction petition, Weitzel asked the postconviction court to consider his request for relief in the interests of justice despite the general two-year statute of limitations, citing section 590.01, subdivision 4(b)(5), of the Minnesota Statutes, and he presented argument in support of that request in his accompanying memorandum of law.

The state promptly filed an answer to the petition in which it contended generally that Weitzel's "convictions and sentences are lawful and proper and should not be vacated and set aside." The state did not mention the general two-year statute of limitations for filing a postconviction petition, see Minn.Stat. § 590.01, subd. 4(a), the exceptions to the two-year limitations period, see Minn.Stat. § 590.01, subd. 4(b), or the additional two-year limitations period that applies to petitions that invoke one of the exceptions, see Minn.Stat. § 590.01, subd. 4(c).

In May 2014, the postconviction court denied Weitzel's petition for postconviction relief. The postconviction court noted that the petition was filed more than two years after Weitzel's conviction became final and denied the petition on the ground that it is untimely. The postconviction court based that determination on two independent reasons: first, that Weitzel did not file the petition within two years of the accrual of his claim, as required by subdivision 4(c), and, second, that Weitzel did not satisfy the requirements of the interests-of-justice exception in subdivision 4(b)(5). Weitzel appeals.

ISSUE

Did the postconviction court err by denying Weitzel's petition on the ground that it is untimely even though the state did not assert the defense of untimeliness in its answer to the petition?

ANALYSIS

Weitzel makes three arguments on appeal. First, he argues that the postconviction court erred by denying his petition on the ground that it is untimely because the state waived the issue of untimeliness by failing to assert it in its answer to the petition. Second, he argues that his guilty plea is invalid on the ground that it is inaccurate because he did not fail to comply with his registration requirement. Third, he argues that his guilty plea is invalid on the ground that it was not intelligently entered due to ineffective assistance of counsel.

The Postconviction Relief Act governs the timeliness of postconviction petitions. Section 590.01, subdivision 4(a), sets forth a general two-year limitations period in which to file a petition for postconviction relief. Minn.Stat. § 590.01, subd. 4(a). The limitations period begins upon the latter of "(1) the entry of judgment of conviction or sentence if no direct appeal is filed; or (2) an appellate court's disposition of petitioner's direct appeal." Id. If the limitations period in subdivision 4(a) has expired, subdivision 4(b) provides that the postconviction court may consider the untimely petition if any of five exceptions applies. Id., subd. 4(b). For example, an exception applies if "the petitioner establishes to the satisfaction of the court that the petition is not frivolous and is in the interests of justice." Id., subd. 4(b)(5). But petitioners do not have an unlimited amount of time in which to file a petition because subdivision 4(c) provides that any petition relying on subdivision 4(b) "must be filed within two years of the date the claim arises." Id., subd. 4(c).

A.

For his first argument, Weitzel contends that the state waived the defense of untimeliness by not asserting the defense in its answer and that the state's waiver should have prevented the postconviction court from considering the issue of untimeliness and denying his petition on that ground. In response, the state contends that the postconviction court had discretion to consider the timeliness of Weitzel's petition even though the state did not assert the defense of untimeliness in its answer. Weitzel relies on two opinions in which the supreme court concluded that the state waived the defense of untimeliness. See Hooper v. State, 838 N.W.2d 775, 780-82 (Minn.2013); Carlton v. State, 816 N.W.2d 590, 606 (Minn.2012).

In Carlton, the supreme court held that "the time limitation in subdivision 4(c) does not operate as a jurisdictional bar, and that it therefore is subject to waiver." 816 N.W.2d at 606. The supreme court declined to consider whether a postconviction petition was barred by the two-year limitations period in subdivision 4(c) because the state had waived the defense by not raising it, either in postconviction proceedings in the district court or in its appellate briefs. Id. In Hooper, the supreme court declined to consider whether a postconviction petition was barred by the two-year limitations period in subdivision 4(a) because the state had waived the defense by not raising it in its appellate brief, even though the state had asserted it in postconviction proceedings in the district court. 838 N.W.2d at 780-82. Collectively, Carlton and Hooper speak to the question whether an appellate court may consider the timeliness of a postconviction petition if the state has not argued untimeliness on appeal. But Carlton and Hooper do not answer the question whether a district court may consider the timeliness of a postconviction petition if the state has not asserted untimeliness in response to the petition. Thus, we reject Weitzel's argument that the postconviction court's denial of his petition conflicts with Carlton and Hooper.

B.

Neither party contends that Weitzel's first argument is governed by any other supreme court opinion or by a precedential opinion of this court. In the absence of binding precedent within Minnesota, we may look to federal law for guidance. See id. (applying opinions of United States Supreme Court); Carlton, 816 N.W.2d at 601, 603-04 (same). The United States Supreme Court considered a very similar issue in Day v. McDonough, 547 U.S. 198, 126 S.Ct. 1675, 164 L.Ed.2d 376 (2006), which concerned a federal statute that provides for a one-year limitations period in which a state-court criminal offender may file a petition for a writ of habeas corpus in a federal district court. 28 U.S.C. § 2244(d)(1)(A) (2012). In Day, the State of Florida filed an answer in which it asserted that, after considering the days when the limitations period was tolled, the habeas petition was timely. 547 U.S. at 201, 126 S.Ct. at 1679. The magistrate judge, however, determined that the state had miscalculated the number of tolled days and that the petition actually was filed after the one-year limitations period. Id. at 201-02, 126 S.Ct. at 1679. The magistrate judge gave Day an opportunity to show cause why the petition should not be dismissed as untimely. Id. at 202, 126 S.Ct. at 1679. The magistrate judge rejected Day's reasons and recommended that the petition be dismissed as untimely. Id. The district court adopted the recommendation and dismissed the petition. Id. The United States Court of Appeals for the Eleventh Circuit affirmed. Id.

The Supreme Court in Day initially noted that the applicable statute of limitations is not a jurisdictional bar and, thus, a federal district court is not obligated to consider untimeliness if a state has not asserted it. Id. at 205, 126 S.Ct. at 1681. But the Court also noted that a federal district court may consider the timeliness of a habeas petition because the untimeliness defense is among a group of defenses that "implicat[e] values beyond the concerns of the parties," such as judicial efficiency, conservation of judicial resources, accuracy of judgments, and finality. Id. at 205-06, 126 S.Ct. at 1681-82 (alteration in original) (quoting Acosta v. Artuz, 221 F.3d 117, 123 (2d Cir.2000)). Accordingly, the Court set forth the following rule of law:

Id. at 209-10, 126 S.Ct. at 1684 (quotations and citations omitted). The Court affirmed the decisions of the lower courts, concluding that the federal district court did not abuse its discretion by considering the issue of untimeliness because, among other things, the magistrate judge "gave Day due notice and a fair opportunity to show why the limitation period should not yield dismissal of the petition" and "nothing in the record suggests that the State `strategically' withheld the defense or chose to relinquish it." Id. at 210-11, 126 S.Ct. at 1684.

In a subsequent case, the Supreme Court clarified and limited Day by holding that a federal court may not consider the timeliness of a habeas petition and dismiss it on that basis if the state has not merely forfeited the statute-of-limitations defense but, rather, has intentionally, knowingly, and expressly waived it. Wood v. Milyard, ___ U.S. ___, 132 S.Ct. 1826, 1834-35, 182 L.Ed.2d 733 (2012).1 Our supreme court cited and relied on Day in Carlton. See 816 N.W.2d at 603 (citing Day for proposition that statute of limitations is not jurisdictional bar); see also Matakis v. State, 862 N.W.2d 33, 39 (Minn.2015) (distinguishing Day); Reed v. State, 793 N.W.2d 725, 731 (Minn.2010) (citing Day for proposition that statute of limitations is not jurisdictional). Furthermore, the Supreme Court's opinions in Day and Wood provide a useful means of resolving Weitzel's first argument.

C.

In applying Day and Wood to the facts of this case, we first note that the state's answer to Weitzel's petition does not give any indication that the state intentionally, knowingly, and expressly waived the defense of untimeliness. Cf. Wood, 132 S.Ct. at 1834-35. Accordingly, the postconviction court was "permitted, but not obliged, to consider, sua sponte, the timeliness of [the postconviction] petition." See Day, 547 U.S. at 209, 126 S.Ct. at 1684. Before doing so, however, the postconviction court was obligated to "accord the parties fair notice and an opportunity to present their positions" on the particular issues that the postconviction court was inclined to consider and resolve. See id. at 210, 126 S.Ct. at 1684. It was obvious to the postconviction court that Weitzel's petition does not comply with the general two-year limitations period in subdivision 4(a). The petition conceded the point by invoking the interests-of-justice exception in subdivision 4(b)(5). Furthermore, because Weitzel presented a well-developed argument for the interests-of-justice exception in his memorandum, the postconviction court had no need to give him an additional opportunity to present his position with respect to that issue before considering it and deciding that the interests-of-justice exception does not apply.2 See id.

The issue whether the petition was barred by the two-year limitations period in subdivision 4(c), however, is an issue that was not raised in Weitzel's petition or the state's answer. Under Day, the postconviction court should have given Weitzel an opportunity to present his position on subdivision 4(c) before considering and disposing of the petition on that ground. See id.; see also Carlton, 816 N.W.2d at 606 (concluding that state did not preserve argument concerning subdivision 4(c)). The record indicates that the postconviction court did not give notice to the parties of its intention to consider whether Weitzel had satisfied the requirements of subdivision 4(c). The postconviction court resolved that issue by determining that Weitzel had not satisfied the requirements of subdivision 4(c), and that determination provided a second reason for denying the petition. But the lack of notice and opportunity to present argument concerning subdivision 4(c) is inconsequential because the postconviction court also determined that Weitzel's petition should be denied on the ground that he does not satisfy the interests-of-justice exception of subdivision 4(b)(5), which was the only exception in subdivision 4(b) that he invoked in his petition and argued in the accompanying memorandum. Weitzel had an opportunity to present argument concerning the interests-of-justice exception in subdivision 4(b)(5) before the postconviction court denied his petition on that ground. Weitzel's failure to satisfy the interests-of-justice exception is a sufficient basis for the postconviction court's denial of the petition. Thus, the postconviction court did not abuse its discretion by denying Weitzel's petition on the ground of untimeliness.

Weitzel's first argument is limited to a challenge to the district court's authority to consider the issue of untimeliness and to dispose of the petition on that ground. He does not argue that the postconviction court erred in its substantive analysis of the interests-of-justice exception. Therefore, we have fully resolved Weitzel's first argument. In light of that resolution, we need not consider his second and third arguments, which address the merits of his petition.

DECISION

The postconviction court did not abuse its discretion by considering whether Weitzel's postconviction petition is timely and by denying the petition as untimely because Weitzel did not satisfy the interest-of-justice exception to the two-year statute of limitations.

Affirmed.
