¶1 — In these consolidated personal restraint petitions (PRPs), Michael Robert Bybee and Ethan Durden seek relief from personal restraint imposed after each pleaded guilty to first degree kidnapping (with a firearm *262sentencing enhancement), first degree robbery, two counts of first degree burglary, and first degree unlawful possession of a firearm. Both seek dismissal of their kidnapping convictions as incidental to their robbery convictions under State v. Korum, 120 Wn. App. 686, 702-07, 86 P.3d 166 (2004), aff’d in part and rev’d in part, 157 Wn.2d 614, 141 P.3d 13 (2006).1 They also contend that their PRPs meet several exceptions to the one-year time-bar. Because Bybee and Durden meet no time-bar exceptions, we deny their PRPs as untimely.

*262FACTS

¶2 Michael Bybee and Ethan Durden pleaded guilty to first degree kidnapping with a firearm sentencing enhancement, first degree robbery, two counts of first degree burglary, and first degree unlawful possession of a firearm in Pierce County Superior Court cause nos. 97-1-03611-1 and 97-1-03610-2. Bybee’s judgment and sentence2 became final on July 17, 2000, and Durden’s judgment and sentence3 became final on November 30, 2000, when we issued the mandates disposing of their respective direct appeals. See RCW 10.73.090(3)(b). Bybee filed a PRP challenging his judgment and sentence on September 28, 2006. Durden filed his PRP on August 17, 2007. We have consolidated their PRPs.

ANALYSIS

I. One-Year Time Limit for Filing a PRP

¶3 A PRP is a form of collateral attack on a criminal judgment and sentence. RCW 10.73.090(2). Court rules and statutes bar a restrained person from filing PRPs or other *263collateral attacks more than one year after the judgment becomes final. RCW 10.73.090(1); RAP 16.4(d).

¶4 Bybee and Durden filed their PRPs more than one year after their respective judgments became final. Therefore, we must reject both PRPs as untimely unless they fall within an exemption or an exception to the one-year limit. They do not, however, meet any exemption or exception.

II. Facial Invalidity Exemption

¶5 If a petitioner proves his judgment and sentence is facially invalid or that the issuing court lacked jurisdiction, the petitioner may collaterally attack the judgment at any time. RCW 10.73.090(1). But neither Bybee nor Durden briefed such a claim.4 Thus, the one year time-bar applies and we must deny relief unless they can show that their PRPs fall within a statutory exception.

III. Statutory Exceptions to One-Year Time Limit

¶6 A petitioner may file an otherwise untimely PRP by demonstrating that bis restraint is unlawful based solely on one or more of the following six grounds that RCW 10.73.100 lists as exceptions to the one-year time limit:

The time limit specified in RCW 10.73.090 does not apply to a petition or motion that is based solely on one or more of the following grounds:

*264(1) Newly discovered evidence, if the defendant acted with reasonable diligence in discovering the evidence and filing the petition or motion;

(2) The statute that the defendant was convicted of violating was unconstitutional on its face or as applied to the defendant’s conduct;

(3) The conviction was barred by double jeopardy under Amendment V of the United States Constitution or Article I, section 9 of the state Constitution;

(4) The defendant pled not guilty and the evidence introduced at trial was insufficient to support the conviction;

(5) The sentence imposed was in excess of the court’s jurisdiction; or

(6) There has been a significant change in the law, whether substantive or procedural, which is material to the conviction, sentence, or other order entered in a criminal or civil proceeding instituted by the state or local government, and either the legislature has expressly provided that the change in the law is to be applied retroactively, or a court, in interpreting a change in the law that lacks express legislative intent regarding retroactive application, determines that sufficient reasons exist to require retroactive application of the changed legal standard.

RCW 10.73.100 (emphasis added). Whether Bybee’s and Durden’s petitions meet a statutory exception to the time-bar thus depends entirely on the nature of their substantive grounds for relief. We examine each in turn.

A. Merger and Double Jeopardy—Korum

¶7 Both Bybee and Durden argue that their restraint is unlawful based on our Korum decision. They primarily claim that we held Korum’s kidnapping convictions merged with his robbery convictions because Korum’s kidnappings were merely incidental to his robberies. Both Bybee and Durden assert that the robbery and the kidnapping to which they pleaded guilty were identical to those charged against Korum. Bybee and Durden argue, therefore, that *265(1) their respective kidnapping convictions also merge with their robbery convictions under Korum and (2) because convicting a defendant of two merged crimes would violate double jeopardy, we must similarly vacate their kidnapping convictions under Korum. State v. Freeman, 153 Wn.2d 765, 770-73, 108 P.3d 753 (2005).

¶8 Based on their substantive merger/double jeopardy argument, Bybee and Durden claim to meet four statutory time-bar exceptions for filing PRPs. First, they argue that their kidnapping convictions place them in double jeopardy and, therefore, the kidnapping statute is unconstitutional as applied to them. RCW 10.73.100(2). Second, again based on their merger argument, they argue that double jeopardy bars their kidnapping convictions. RCW 10.73.100(3). Third, they argue that their kidnapping and robbery convictions merge and, therefore, the sentencing court lacked jurisdiction to sentence them for both crimes. RCW 10.73.100(5).

¶9 Finally, they argue that by merging codefendant Korum’s kidnapping and robbery jury convictions, Korum was a significant, material, and retroactive change in the law, namely a change in the interpretation of the kidnapping and robbery statutes to require merger, despite contrary Washington State Supreme Court precedent. Bybee and Durden also appear to argue that Korum’s “change in the law,” whatever its legal basis, should apply to them retroactively simply because they were originally Korum’s codefendants before they pleaded guilty and he, eventually, went to trial. Thus, we examine Korum’s rationale to determine whether it applies to Bybee’s and Durden’s claimed time-bar exceptions.

¶10 Bybee and Durden characterize our Korum holding as merging Korum’s jury-trial kidnapping convictions with his jury-trial robbery convictions, apparently because we held that under the facts proved at Korum’s trial, the kidnappings were merely incidental to the robberies and, therefore, the evidence was insufficient to support kidnapping convictions separate from the robbery convictions. *266Bybee and Durden argue that their guilty-plea kidnapping convictions were identical to Koruxn’s jury-trial convictions and, therefore, their kidnapping convictions similarly should merge with their robbery convictions. But Bybee and Durden misapprehend our holding in Korum. Thus, all of their claimed grounds for statutory exceptions to the one-year time limit fail.

¶11 In Korum, we dismissed several of the jury’s kidnapping convictions because they were “incidental to the robberies” for which the jury also convicted Korum. Korum, 120 Wn. App. at 689. The Washington State Supreme Court affirmed our dismissal of these kidnapping counts without substantive discussion because the State did not seek review of that part of our decision. Korum, 157 Wn.2d at 620, 623-25.5 Korum’s kidnapping convictions were “incidental to the robberies” because the jury received insufficient evidence to prove kidnappings independent of and with a different purpose than the robberies.6 E.g., Korum, 120 Wn. App. at 702-03.

¶12 In Korum, we explicitly relied on State v. Green, 94 Wn.2d 216, 225-28, 616 P.2d 628 (1980), a case that applied what was then a new sufficient-evidence standard to hold that evidence of restraint (necessary to prove kidnapping) was insufficient under the facts of that case to prove kidnapping because that same restraint was incidental to an attempted rape.7 Although Green borrowed the “inciden*267tal restraint” concept from an earlier merger case,8 it incorporated this concept into a new standard for determining sufficiency of evidence on appeal.9 Thus, as we applied Green in Korum, when the only evidence presented to the jury demonstrates that the restraint is merely incidental to completing another crime, the jury has not received sufficient evidence to convict the defendant of a separately charged kidnapping.

¶13 We dismissed Korum’s kidnapping convictions because the jury received insufficient evidence of independent kidnappings distinct from the robberies, not because those convictions merged or violated double jeopardy. Bybee’s and Durden’s claims for Koram-based relief, therefore, do not meet the time-bar exceptions for convictions under an unconstitutional statute as applied, for double jeopardy violations, for sentences in excess of jurisdiction, or for a significant change in merger law.

B. Guilty Plea Waives Challenge to Sufficiency of Evidence

¶14 In his reply brief, adopted by Durden, Bybee asserts a fifth statutory exception under RCW 10.73.100(4), arguing that we dismissed Korum’s kidnapping convictions because insufficient evidence supported them. Although we agree with this characterization of our holding in Korum, it does not advance Durden’s and Bybee’s arguments here. RCW 10.73.100(4) expressly limits the insufficient evidence exception to the one-year time requirement to petitioners who went to trial. Accordingly, because both Bybee and Durden pleaded guilty and neither went to trial, they do not meet this statutory exception.

*268¶15 Furthermore, a guilty plea waives or renders irrelevant all constitutional violations that occurred before the guilty plea, except those related to the circumstances of the plea or to the government’s legal power to prosecute regardless of factual guilt. See Menna v. New York, 423 U.S. 61, 63 n.2, 96 S. Ct. 241, 46 L. Ed. 2d 195 (1975); State v. Saylors, 70 Wn.2d 7, 9, 422 P.2d 477 (1966); In re Habeas Corpus of Woods, 68 Wn.2d 601, 606-07, 414 P.2d 601, cert. denied, 385 U.S. 905 (1966); In re Habeas Corpus of Salter, 50 Wn.2d 603, 606, 313 P.2d 700 (1957). By pleading guilty, a defendant admits factual and legal guilt for the charged crime. E.g., United States v. Broce, 488 U.S. 563, 570, 109 S. Ct. 757, 102 L. Ed. 2d 927 (1989); see also State v. Davis, 29 Wn. App. 691, 696, 630 P.2d 938 (1981). The guilty plea thus provides a sufficient and independent factual basis for conviction and punishment. See Haring v. Prosise, 462 U.S. 306, 321, 103 S. Ct. 2368, 76 L. Ed. 2d 595 (1983); Menna, 423 U.S. at 63 n.2. A claim that potential trial evidence, never presented because the defendant pleaded guilty, would have been constitutionally insufficient is therefore irrelevant and precluded by the guilty plea. See State v. Carrier, 36 Wn. App. 755, 757, 677 P.2d 768 (1984).

¶16 Bybee and Durden pleaded guilty, but they now seek the benefit of legal rulings obtained by a codefendant who proceeded to trial. They assert that no published case governs such a situation. In Broce, however, the United States Supreme Court rejected a similar claim, stating, “[A] strategic miscalculation” does “not justify setting aside an otherwise valid guilty plea.” Broce, 488 U.S. at 571. This Broce principle provides additional support for our holding here. When Bybee and Durden pleaded guilty to both kidnapping and robbery, they admitted a sufficient factual basis for both charges. Whether the State’s proof of restraint, had they gone to trial, would have been insufficient as merely incidental to the robbery under Korum, is therefore unknown and irrelevant.

¶17 Bybee’s and Durden’s guilty pleas bar them from claiming insufficient evidence based on Korum’s incidental *269restraint analysis.10 Thus, Bybee and Durden do not meet their final claimed time-bar exception for PRPs based on a material, significant, and retroactive change in the law. See RCW 10.73.100(6).

¶18 We hold, therefore, that Bybee’s and Durden’s PRPs are untimely. Accordingly, we deny their requests for relief from restraint.
