— This court granted discretionary review of orders dismissing two personal restraint petitions filed by the petitioner, Mark Crabtree. The cases have been consolidated and were initially deferred pending this court’s decision in State v. Aho.1 The Court of Appeals properly dismissed the two personal restraint petitions (PRPs); however, between the time the PRPs were dismissed and the time Crabtree petitioned for discretionary review there was an intervening change in the law which may be relevant to this case. We hold that the intervening change in the law does not constitute good cause to grant the petition and therefore deny Crabtree’s PRP.
*580Crabtree was charged with five sexual assaults against children. On April 18, 1989, he entered guilty pleas to charges of first degree child rape (count II), first degree child molestation (count IV), and first degree statutory rape (count V). As part of the plea agreement, the State dismissed the charges of first degree statutory rape (count I) and indecent liberties (count III). The court sentenced Crabtree to concurrent terms of 89 months (count II), 41 months (count IV), and 61 months (count V). A one-year term of community placement was imposed as part of his sentence for counts II and IV pursuant to former RCW 9.94A.120(8)(a) (1988).2
Crabtree began serving his term of community placement after earning 27 months of good time. He then violated the terms of his community placement and was returned to prison. Following his return to prison, Crabtree filed two PRPs.
On January 7, 1998, Crabtree filed his first PRP with the Court of Appeals claiming the community placement portion of his sentence violated the ex post facto clause because the community placement statute applies only to crimes committed on or after July 1, 1998. That PRP was dismissed as time-barred under RCW 10.73.090(1).3 On July 7, 1998, while the first petition was still pending, Crabtree filed a pro se motion to withdraw his guilty plea. Crabtree challenged his convictions on the basis of an ex post facto violation, the court exceeded its jurisdiction by accepting the pleas, ineffective assistance of counsel, and newly discovered evidence. That motion was transferred to the *581Court of Appeals and handled as a PRP. This second PRP was procedurally barred. The Court of Appeals stated that Crabtree failed to show good cause for reraising his sentencing claim and for not making his other arguments in the first petition. The second petition was deemed a prohibited successive petition pursuant to RCW 10.73.140.4 Crabtree made motions for discretionary review by this court of the two Court of Appeals orders dismissing the PRPs. We granted discretionary review.
ISSUES
(1) Is it proper for this court to review these consolidated motions?
(2) If so, has Crabtree shown “good cause” for this court to grant his petition?
DISCUSSION
In the interest of judicial economy we will review these consolidated motions. Crabtree filed two PRPs. The first was time-barred because it was filed more than one year after his conviction became final, and the second did not show good cause why new issues were raised that had not been raised in the first PRP. His convictions are facially valid. Therefore, both petitions are barred by RCW *58210.73.090 unless based solely on one or more of the grounds listed in RCW 10.73.100. Additionally, when the Court of Appeals “receives a personal restraint petition it may not consider under the terms of RCW 10.73.140, [the proper procedure] is either to dismiss it, or to transfer it to this Court if it determines RAP 16.4(d) might apply.” In re Personal Restraint of Johnson, 131 Wn.2d 558, 566, 933 P.2d 1019 (1997). In this case, the Court of Appeals exercised the proper procedure in dismissing both petitions. We are faced with the issue of determining whether procedurally we may consider the PRPs under a RAP 16.4(d) “good cause” analysis after the petitions have been dismissed. This court may grant relief even if the Court of Appeals could not do so. See id.
In Johnson, the petitioner filed his first PRP protesting his offender score. Id. at 562. The Court of Appeals denied the PRP based on State v. Chavez, 52 Wn. App. 796, 764 P.2d 659 (1988) (holding overlapping sentences not considered as one offense for purposes of calculating offender score). Chavez was subsequently overruled by In re Personal Restraint of Sietz, 124 Wn.2d 645, 648, 880 P.2d 34 (1994) (concluding for offenses committed before July 1, 1986, revoked probation or parole merges with another offense concurrently, establishing “ ‘adult conviction served concurrently’ ” for purposes of former RCW 9.94A.360(6)(c) (1994) in calculating offender score). Johnson then filed his second PRP citing Sietz. This court held that RCW 10.73.140 did not bar this court’s consideration of Johnson’s PRP. In re Personal Restraint of Johnson, 131 Wn.2d at 566. And the determination to be made was whether the petitioner had shown good cause under RAP 16.4(d) for reconsideration of the petition. Id.
Discretionary review of both PRPs in this case was sought and granted. RAP 16.14(c) states that “ [i] f the petition is dismissed by the Chief Judge or decided by the Court of Appeals on the merits, the decision is subject to review by the Supreme Court only by a motion for discretionary review on the terms and in the manner provided in *583rule 13.5(a), (b), and (c).” In between the time the petitions were dismissed and the time review by this court was granted, the Aho case was decided. The Aho case is a subsequent change in the law that may qualify as “good cause” for granting the petition. This court does not have to consider Crabtree’s petitions because they were time-barred due to the fact that none of the RCW 10.73.100 exceptions to the one-year limit on collateral attacks applied. However, if this court simply denies review, Crabtree may bring a successive petition arguing a subsequent change in the law. In the interest of judicial economy, we will determine whether there is good cause to grant Crabtree’s petition.
Crabtree claims (1) a petitioner is unlawfully restrained when both state and federal constitutional due process rights are violated due to imposition of a sentence without statutory authority; (2) a PRP which raises obvious and inherently prejudicial constitutional errors is not time-barred; (3) a plea of guilty must be vacated when a defendant’s due process rights were violated by charging, convicting, and sentencing the defendant under nonretroactive statutes that were not in effect during a portion of the charging period; (4) assistance of counsel was ineffective; and (5) newly discovered evidence in the form of recantation of a victim’s testimony is grounds for relief by PRP and for withdrawal of guilty plea. Crabtree’s claims should be denied because he pleaded guilty to the crimes occurring during the statutory time, and there is evidence that shows Crabtree committed the offenses during the statutory period. Moreover, counsel was effective in light of all the evidence before this court. And finally, the newly discovered evidence argument is without merit.
This court may grant Crabtree’s petition if “good cause” is shown. See In re Personal Restraint of Johnson, 131 Wn.2d 558. An intervening change in the law has been recognized as good cause for granting a successive PRP. Id. In this case, the Aho decision may be seen as an intervening change in the law constituting good cause to grant *584Crabtree’s petition. Claims based on a significant, intervening, retroactive change in the law are exempt from the statute. RCW 10.73.100(6). Such changes also constitute “good cause” for either reviewing a previously rejected claim or failing to raise a claim in a prior petition. See In re Personal Restraint of Holmes, 121 Wn.2d 327, 331, 849 P.2d 1221 (1993). Thus, if Aho is seen as “new” law, Crabtree can challenge his convictions and sentence without regard to procedural bars.
The petitioner in Aho claimed that his convictions for child molestation violated “ex post facto prohibitions because the statute under which he was charged and under which the jury was instructed did not take effect until approximately a year and a half after the beginning of the charging period.” State v. Aho, 137 Wn.2d 736, 739, 975 P.2d 512 (1999). This court concluded that the Aho case involved a due process question, not an ex post facto issue.5 In granting Aho’s claim, this court reasoned that because the jury was not instructed to identify the time of specific occurrences constituting the offense, Aho may have been illegally convicted based upon acts occurring before the effective date of the child molestation statute. Id. at 743. A direct violation of the clear legislative mandate that the statute not be applied to acts committed before July 1988 occurred as a result of both the state and defense counsel permitting the matter to go forward despite the fact that the charging period, which was included in the jury instruction, included a substantial period of time before the effective date of the statute. Id. at 743. Aho was charged and convicted for an offense that may have occurred before the effective date of the statute. Id. at 744.
*585The Aho case differs from Crabtree’s situation. Crabtree entered a guilty plea and in doing so admitted he committed the offenses between June 1, 1988 and August 31, 1988.6 Moreover, there is evidence outside the guilty plea, showing that Crabtree did commit the offenses during the statutory period. There was neither an ex post facto violation nor a due process violation because Crabtree was not convicted for crimes occurring before the statutory period. The charging period did include one month, out of three, before the effective date of the statute; however, Crabtree was not prejudiced by this because he was not convicted of an offense that may have occurred during the month before the statute came into effect. Crabtree’s due process rights would have been violated if the offenses for which the community placement was imposed had occurred before July 1, 1988. However, in Crabtree’s guilty plea statement he admitted he committed rape of a child and child molestation between June 1, 1988 and August 31, 1988. This constituted an admission of criminal acts between July 1 and August 31. Crabtree was convicted and sentenced for crimes he admitted occurred after the effective date of the statute.
CrR 4.2(d) requires that “[t]he court shall not enter a judgment upon a plea of guilty unless it is satisfied that there is a factual basis for the plea.” This requirement protects defendants who are in the position of voluntarily pleading guilty with an understanding of the nature of the charge, but who do not realize that the conduct does not actually fall within the charge. See State v. Zumwalt, 79 Wn. App. 124, 901 P.2d 319 (1995). Generally, the factual basis requirement requires the judge, before accepting the guilty plea, to determine that the defendant’s admitted conduct constitutes the charged offenses. In this case we have the police report, information, determination of probable cause, guilty plea, plea agreement, and psychological evaluation stating that the offenses occurred within the statutory period.
*586Following Crabtree’s arrest, he denied committing the offenses. On the eve of the trial, however, Crabtree changed his plea to guilty. Crabtree wanted to seek treatment for his problems, so the court provided funds to have Crabtree examined by a sexual deviancy specialist to determine if he would be an appropriate candidate for a special sex offender sentencing alternative sentence. The psychological evaluation says that “[i]n August, 1988, Mr. Crabtree states that he assaulted Jessica and David.” Resp’t’s Br., App. E at 3. Crabtree went on to specifically outline what occurred when he was babysitting the two children in August 1988. Thus, in the evaluation Crabtree requested, he admitted to committing the offenses during the statutory time.
The police report contains an interview of the mother of the victims of counts II and IV. In the interview she stated:
Well, MARK had his uh two step children, uh, CASSIE and CHRISTOPHER, and his son, JUSTIN, come out on July 15th and we had em until the 31st and he took ‘era to um to back to his mother’s to Montana for his uh estranged wife to pick 'em up. And um, anyway, I had asked JESSICA when exactly the last event happened and she said, “It was the weekend after, after um MARK had taken the kids back to Montana.” And that, I remember the night clearly because that wa. . . the kids went to their dad’s for a week, and they came back that day and he had to babysit and the next day I was going out to my mother’s and he was up about, I didn’t come in until about 3 o’clock in the morning, because I went out with a couple of friends and um that’s how I remember it because the kids went the next week out to my folks’ and they said nothing happened after that.
Resp’t’s Br., App. C at 5-6. The date of the last occurrence was after July 1, 1988. This is within the statutory time frame. The police report, information, determination of probable cause, guilty plea, plea agreement, and psychological evaluation show that Crabtree committed sexual offenses after July 1, 1988.
The record also indicates the sentencing court was aware *587of the requirements of former RCW 9.94A.120(8)(a) because Crabtree was not sentenced to community placement for count V, which occurred in March of 1987. In light of this and the documents before the sentencing court, Crabtree was not convicted of crimes occurring before the effective date of the statute.
Crabtree also alleges constitutional errors in the application of the statute and in the charging document itself. In both cases the petitioner must show actual prejudice. See In re Personal Restraint of St. Pierre, 118 Wn.2d 321, 328, 823 P.2d 492 (1992) (where the error does not give rise to a conclusive presumption of prejudice, a petitioner must establish by a preponderance of the evidence that a constitutional error resulted in actual and substantial prejudice); In re Personal Restraint of Cook, 114 Wn.2d 802, 810-11, 792 P.2d 506 (1990); State v. Kjorsvik, 117 Wn.2d 93, 105-06, 812 P.2d 86 (1991) (employing a two-prong test: (1) do the necessary facts appear in any form, or by fair construction can they be found, in the charging document; and, if so, (2) can the defendant show that he or she was nonetheless actually prejudiced by the inartful language which caused a lack of notice). Crabtree admitted the offenses occurred after the statute came into effect. He was not prejudiced by the charging document which included the month before the statute came into effect, and he was not prejudiced by how the statute was applied because there is evidence he committed the crimes within the statutory time.
Crabtree’s ineffective assistance of counsel claims fail as well. To prevail in an ineffective assistance of counsel claim, a defendant must show: “(1) defense counsel’s representation was deficient, i.e., it fell below an objective standard of reasonableness based on consideration of all the circumstances; and (2) defense counsel’s deficient representation prejudiced the defendant, i.e., there is a reasonable probability that, except for counsel’s unprofessional errors, the result of the proceeding would have been different.” State v. McFarland, 127 Wn.2d 322, 334-35, 899 P.2d *5881251 (1995) (citing State v. Thomas, 109 Wn.2d 222, 225-26, 743 P.2d 816 (1987) (applying the two-prong test in Strickland v. Washington, 466 U.S. 668, 687, 104 S. Ct. 2052, 80 L. Ed. 2d 674 (1984))). In light of Crabtree’s guilty plea, the police report, and Crabtree’s admissions to the psychologist, counsel’s assistance was effective. Crabtree was not prejudiced because he admitted to the crimes occurring after the statute came into effect.
Crabtree also argues that his guilty plea on count V should be withdrawn due to newly discovered evidence, i.e., an October 7, 1998 affidavit from the victim stating Crabtree never had sexual intercourse with him. This claim is without merit, as the Court of Appeals stated in the Order Dismissing Personal Restraint Petition:
To obtain a new trial based on newly discovered evidence, a defendant must prove the evidence could not have been discovered before trial by the exercise of due diligence. Crabtree offers no reason for waiting 9 years to challenge his plea and to obtain this statement from the victim. He has thus failed to establish due diligence.
Furthermore, because he pleaded guilty, his argument is without merit. He does not complain he was tricked, coerced or threatened to plead guilty. The plea form, which Crabtree signed, states he was making the plea freely and voluntarily, without threats or promises. Finally, Crabtree provides no support for his bald assertion that the only evidence of sexual intercourse was the victim’s statement.
Pet’r’s Supplemental Br. at A-69 (footnotes omitted) (citing State v. Macon, 128 Wn.2d 784, 803, 911 P.2d 1004 (1996); State v. Arnold, 81 Wn. App. 379, 386-87, 914 P.2d 762 (victim’s recantation insufficient to grant new trial in part because he admitted guilt, rather than pleading not guilty or entering a plea under North Carolina v. Alford, 400 U.S. 25, 91 S. Ct. 160, 27 L. Ed. 2d 162 (1970)), review denied, 130 Wn.2d 1003, 925 P.2d 989 (1996)). Crabtree has not proven that this evidence could not be discovered before *589trial with the exercise of due diligence and therefore his claim to withdraw his guilty plea should be denied.7
CONCLUSION
Crabtree’s petition should be denied because he is unable to show good cause why this court should grant his petition. Aho is not an intervening change in the law that is material to Crabtree’s case because Crabtree did not suffer the same due process violations. In this case the question of whether Crabtree may have been convicted of offenses occurring outside the statutory time does not exist. Crabtree admitted that he committed the offenses after the statute came into effect. This is shown in the police report, information, determination of probable cause, guilty plea, and psychological evaluation. In light of the admissions made by the petitioner, the assistance of counsel was effective. Finally, the withdrawal of his guilty plea is denied because it is without merit.
The consolidated petitions are denied.

Former RCW 9.94A.120(8)(a) states:
When a court sentences a person to a term of total confinement to the custody of the department of corrections for an offense categorized as a sex offense ... committed on or after July 1,1988, the court shall in addition to the other terms of the sentence, sentence the offender to a one-year term of community placement....
RCW 10.73.090(1) states that “[n]o petition or motion for collateral attack on a judgment and sentence in a criminal case may be filed more than one year after the judgment becomes final if the judgment and sentence is valid on its face and was rendered by a court of competent jurisdiction.”
RCW 10.73.140 states:
If a person has previously filed a petition for personal restraint, the court of appeals will not consider the petition unless the person certifies that he or she has not filed a previous petition on similar grounds, and shows good cause why the petitioner did not raise the new grounds in the previous petition. Upon receipt of a personal restraint petition, the court of appeals shall review the petition and determine whether the person has previously filed a petition or petitions and if so, compare them. If upon review, the court of appeals finds that the petitioner has previously raised the same grounds for review, or that the petitioner has failed to show good cause why the ground was not raised earlier, the court of appeals shall dismiss the petition on its own motion without requiring the state to respond to the' petition. Upon receipt of a first or subsequent petition, the court of appeals shall, whenever possible, review the petition and determine if the petition is based on frivolous grounds. If frivolous, the court of appeals shall dismiss the petition on its own motion without first requiring the state to respond to the petition.
This court stated “the United States Supreme Court explained that the ex post facto prohibition applies to the legislative branch, and thus judicial decisions which are applied retroactively may raise due process concerns, but do not fall within the ex post facto clause itself.” Aho, 137 Wn.2d at 742; Marks v. United States, 430 U.S. 188, 191, 97 S. Ct. 990, 51 L. Ed. 2d 260 (1977) Ht]he Ex Post Facto Clause is a limitation upon the powers of the Legislature and does not of its own force apply to the Judicial Branch of government” (citation omitted)). The laws at issue in both Aho and this case were not enacted to apply retroactively, so in both cases the issue involves a violation of due process. See Laws of 1988, ch. 145, § 25; Laws of 1988, ch. 153, § 2.
The effective date of the statute under which community placement was imposed was July 1, 1988.
The victim’s statement, dated October 7, 1998, was: “I Jeremy Michael Seitzinger make this statement under my own free will. My uncle Mark A. Crabtree has not had sexual intercourse or sexual relations with me at any time in the past.” Pet’r’s Supplemental Br. at A-95.
