OPINION
MANNHEIMER, Judge.Hugh R. Tazruk appeals the superior court's dismissal of his petition for post-conviction relief. Based on the record, the superior court was completely justified in dismissing Tazruk's petition because Tazruk failed to present a prima facie case that he was entitled to relief.
The only real issue in this case is the possibility that Tazruk received ineffective assistance of counsel in the investigation and preparation of his petition for post-conviction relief. Normally, an appellate court will not consider claims of ineffective assistance for the first time on appeal-because, in most instances, the appellate record is inadequate to allow us to meaningfully assess the competence of the attorney's efforts. But Tazruk's case is atypical. As we explain here, the record of the proceedings in the superior court establishes a prima facie case that Tazruk received ineffective assistance. We must therefore remand Tazruk's case to the superior court for further investigation of this issue.
The proceedings in the superior court
In January 2000, Tazruk was convicted of third-degree sexual assault. Eighteen months later, in July 2001, Tazruk filed a pro se petition for post-conviction relief. Because he was indigent, the Office of Public Advocacy was appointed to represent him in this post-conviction relief litigation.
As we explained in Griffin v. State, 18 P.8d 71 (Alaska App.2001), when an attorney is appointed to represent an indigent petitioner for post-conviction relief, the attorney must do one of three things: (1) elect to go forward on the petition in its current form (i.e., as drafted by the client); or (2) draft and file an amended petition; or (8) explain to the court in detail why the petitioner has no *689colorable claims for relief. Griffin, 18 P.3d at 77, construing Alaska Criminal Rule 85.1(e)(2).
Assistant Public Advocate David K. Allen, the attorney appointed to represent Tazruk, chose to follow the first path: he gave notice that he intended to proceed on the claims contained in Tazruk's existing petition.
Three months later, the State moved to dismiss Tazruk's petition in its entirety. The State argued that Tazruk had failed to present a prima facie case with respect to any of the claims contained in his petition. In response, Mr. Allen filed a notice that he "Iwould] not be filing an opposition to the State's motion to dismiss". However, he reminded the superior court that "[the court must make an independent determination of the merits of the State's motion".
Superior Court Judge Mary E. Greene subsequently issued a three-page order dismissing Tazruk's petition for post-conviction relief. In her order, Judge Greene reviewed Tazruk's five claims and, with respect to each one, she concluded that Tazruk had failed to present a prima facie case.
Tazruk's first claim was that his pre-sentence report falsely stated that Tazruk had previously been convicted of sexual assault-and that, as a result, Tazruk's sentence was enhanced based on this purported prior conviction. But, as Judge Greene explained in her decision, the pre-sentence report did not state that Tazruk had previously been convicted of sexual assault. Rather, the pre-sentence report contained information about two prior assaults that had not been prosecuted. As Judge Greene noted, "the . report was clear that the two prior events had not resulted in convictions". Judge Greene further noted that Tazruk might have challenged the allegations of the two prior sexual assaults 1, but he failed to do so.
Moreover, Judge Greene explained, the two prior sexual assaults were not used as "prior convictions"; that is, they were not used as the basis for subjecting Tazruk to a more severe presumptive term. Instead, they were used to establish aggravating factor AS 12.55.155(c)(21)-i.e., to prove that Tazruk had a history of criminal acts similar to the one for which he was convicted. And, as Judge Greene noted, "convictions are not necessary to establish this aggravating factor. See Turpin v. State, 890 P.2d 1128, 1182 (Alaska App.1995)."
Tazruk's second claim was that there was newly discovered evidence tending to show his innocence. But, as Judge Greene noted, Tazruk based his claim on information contained in the police report in his case. Thus, as a matter of law, Tazruk's evidence was not "newly discovered".2
Tazruk's third claim was that his conviction was subject to collateral attack. But Tazruk failed to articulate a particular reason why this was so, and he failed to present any evidentiary basis for this claim. Thus, Judge Greene concluded that Tazruk had failed to present a prima facie case.
Tazruk's fourth claim was that he should be allowed to withdraw his plea. But again, Tazruk failed to articulate a particular reason why this was so, and he failed to present any evidentiary basis for this claim. Again, Judge Greene concluded that Tazruk had failed to present a prima facie case.
Finally, Tazruk claimed that he received ineffective assistance of counsel from the Public Defender Agency during the investigation and negotiation of his case, leading up to Tazruk's decision to plead no contest to sexual assault. But Tazruk never submitted an affidavit from his trial attorney, nor did he offer an explanation of why his attorney's affidavit could not be obtained. As Judge Greene noted, this Court has re*690peatedly held that a defendant claiming ineffective assistance of counsel must present an affidavit from their former attorney (addressing the allegations of attorney error) or explain why they can not obtain their attorney's affidavit.3 Thus, Judge Greene ruled that Tazruk had failed (as a matter of law) to present a prima facie case of ineffective assistance of counsel.
Having concluded that Tazruk had failed to present a prima facie case with respect to any of his claims, Judge Greene dismissed Tazruk's petition for post-conviction relief.
The proceedings in this appeal
After Judge Greene dismissed Tazruk's petition, Allen filed an appeal on Tazruk's behalf. But in his brief, Allen concedes that Judge Greene's decision was correct. He declares that, given the record in this case and given the established Alaska law governing petitions for post-conviction relief, "no non-frivolous argument can be made" against Judge Greene's ruling.
We agree. It is obvious that Tazruk failed to establish a prima facie case for any of his claims. Thus, on the record before her, Judge Greene properly dismissed Tazruk's petition.
The possibility that Tagruk received ineffective assistance of counsel in the litigation of his petition for post-conviction relief
As explained above, Tazruk filed a pro se petition for post-conviction relief and, because he was indigent, the superior court appointed an attorney to represent him. Under Alaska Criminal Rule 35.1(e), an attorney appointed to represent an indigent petitioner must do one of three things: (1) elect to go forward on the petition as drafted by the client, (2) draft and file an amended petition, or (8) certify to the superior court that the petitioner has no colorable claim for relief.
In Griffin, we concluded that this third course of action was inadequate to protect an indigent petitioner's right to effective assistance of counsel. We held that, instead of merely filing a certificate that the petitioner had no colorable claims, the attorney was obliged to provide the superior court with a detailed explanation of why the petitioner had no colorable claims.4
Our decision in Griffin was based in large measure on the federal Constitution-specifically, the United States Supreme Court's ruling in Smith v. Robbins5 regarding a court's duty to protect an indigent defendant's right to counsel. We concluded that if we did not interpret Criminal Rule 85.1(c)(2) to require a detailed explanation from the petitioner's attorney, the superior court would not be able to comply with its duty under Smith v. Robbins to make sure that the petitioner received zealous and competent representation.6
Tazruk's attorney did not pursue this third course. Instead, he chose the first course-declaring that he would go forward on the claims drafted by Tazruk. But, as explained above, all of the claims listed in Tazruk's petition were either (1) facially meritless or, at best, (2) facially inadequate to survive a motion to dismiss. When the State pointed this out (in its motion to dismiss the petition), Tazruk's attorney did not seek leave to amend or supplement these claims, nor did he ask for further time to investigate the claims and (potentially) adduce more evidence to support them. Instead, Tazruk's attorney announced that he had nothing to say in opposition to the State's motion.
The attorney's work on Tazruk's behalf in this litigation appears to be the post-conviction-relief equivalent of a tactic in criminal prosecutions colloquially known as a "slow plea". In a "slow plea", a defendant charged with a crime persists in a plea of not guilty but then does nothing to defend the charge at trial-allowing the State's evidence to come in unchallenged and unrebutted, and *691then simply waiting for the inevitable adverse verdict.7
What happened in Tazruk's case is seemingly analogous. From the record of the proceedings in the superior court, it appears possible that when Tazruk's attorney endorsed the claims contained in Tagruk's pro se petition, he knew that these claims were all subject to dismissal, and he simply waited until the State got around to asking for judgement on the pleadings-a motion that he did not oppose.
If this is indeed what happened, then either (1) Tazruk did not receive effective assistance of counsel or, alternatively, (2) Tazruk's case presents the same constitutional problem that we addressed in Griffin
Even if we assume that Tazruk did receive effective assistance-that is, even if we assume that a zealous and competent attorney could have done nothing more to advance Tazruk's claims-the fact remains that the record contains no indication that Tagruk's attorney ever investigated these claims, sought to adduce support for them through discovery, or sought to reformulate them so that they might survive a motion to dismiss. The record shows only the attorney's inaction and ultimate concession of defeat. As was true in Griffin, such a record is insufficient to allow the courts to earry out their constitutional duty to make sure that an indigent petitioner receives zealous and competent representation.
We hasten to add that an attorney's decision to adopt the claims stated in their client's existing petition for post-conviction relief does not necessarily bespeak attorney inattention or neglect. One can easily imagine cireumstances in which, even though the attorney adopts their client's statement of post-conviction relief claims, the attorney vigorously pursues those claims through discovery and, in some cases, trial. In such instances, it may turn out-after all the evidence is discovered and heard-that the at-tormney will be forced to concede that the petitioner's claims are no longer arguable. Or, even if the evidence is arguable, the attorney may be forced to concede on appeal that the superior court's resolution of the pertinent factual disputes was not clearly erroneous. In such cases, the fact that the attorney adopted the petitioner's statement of claims, and even the fact that the attorney ultimately conceded that there was no legal basis for attacking the superior court's dismissal of the petition, would be perfectly compatible with the attorney's competent representation of the petitioner's interests. -
But in Tazruk's case, there is no record that the attorney did anything to pursue or develop Tazruk's claims. We do not know whether the attorney actually investigated these claims or otherwise worked to develop them; if he did, there is no record of it. And because of this silent record, we are faced with a Griffin problem. We do not know- and have no way of assessing-whether the attorney zealously represented Tazruk's interests.
Accordingly, we must remand Tazruk's case to the superior court. Tazruk's attorney must provide the superior court with a detailed explanation of why he concluded that Tazruk's claims had no arguable merit. If it appears to the superior court that Tazrul's attorney reached this conclusion without competent investigation of the case, the superior court shall vacate its dismissal of Tazruk's petition and shall appoint a new attorney to represent Tazruk. If it appears to the superior court that Tazruk's attorney did engage in competent investigation of the *692case and reasonably concluded that Tazruk had no colorable claim for post-conviction relief, the superior court shall nevertheless allow Tazruk to respond and argue the contrary. See Criminal Rule 35.1).
We again emphasize that we do not view an attorney's decision to adopt their client's pre-existing claims for post-conviction relief as prima facie evidence of attorney incompetence or lack of zeal on their client's behalf. But in Tazruk's case, his claims were plainly insufficient as written, and yet his attorney adopted those claims without revision. Moreover, the record offers no indication that the attorney did anything to investigate or otherwise pursue those claims. And finally, Tazruk's attorney failed to oppose the State's motion for judgement on the pleadings. Given this combination of facts and events, we must require the same explanation from Tazruk's attorney that we required of the attorney in Griffin.
This case is REMANDED to the superior court for the additional proceedings de-seribed above. The superior court shall notify us of its findings and actions within 45 days of the issuance of this opinion. We retain jurisdiction of this appeal.

In Lewis, this Court held that when a defendant seeks post-conviction relief based on newly discovered evidence, the defendant must meet the same test that governs motions for a new trial based on newly discovered evidence. Id. at 450. That is, the defendant must show that the evidence was not known at the time of the defendant's trial or plea despite the defense team's diligent efforts, and that this new evidence (if presented) probably would have led to the defendant's acquittal.

The court stated:
Perhaps the clearest example of a slow plea is a bargained-for submission [of the case] on the transcript of a preliminary hearing in which the only evidence is the victim's credible testimony, and the defendant does not testify and counsel presents no evidence or argument on defendant's behalf. Such a submission is tantamount to a plea of guilty because the guilt of the defendant is apparent on the basis of the evidence presented at the preliminary hearing and ... conviction is a foregone conclusion if no defense is offered.
