OPINION
STEWART, Judge.After reaching a plea bargain with the State, Christopher J. McCoy, Sr., pleaded no contest to one count of third-degree assault.1 Superior Court Judge Harold M. Brown imposed 4 years' imprisonment with all but 18 months suspended. In this appeal, McCoy does not challenge his sentence. Instead, he argues that Judge Brown erred when he denied McCoy's motion to strike certain portions of the presentence report. Because we reject McCoy's arguments, we affirm the superior court.
The challenged hearsay statements
Before sentencing, McCoy moved to strike certain paragraphs from the "collateral contacts" section of the presentence report and two paragraphs from an addendum to the presentence report that contained informa*749tion about other assaultive conduct by McCoy. McCoy argued the purportedly objectionable paragraphs contained unverified hearsay statements.
Judge Brown ruled that the hearsay statements in the presentence report were sufficiently trustworthy for him to rely on them unless McCoy presented a challenge to their accuracy. He reasoned that the information in the addendum came from police reports in which the victim of the assaults, Michelle McCoy, reported her observations to the police. Judge Brown also noted that the addendum contained "confirming information as to what [the police] did in response." Judge Brown concluded that the other statements in the presentence report, "even though they might be so-called third-hand information, [are] the type of information that the court can consider verified for the purpose of ... this sentencing process."
In Nukapigak v. State,2 the Alaska Supreme Court held that hearsay statements can be considered during sentencing if they are "sufficiently verified to appear trustworthy and the defendant was given the opportunity to deny [the truth of the statements] or present contrary evidence of his own."3 The court defined "verified" as "corroborated or substantiated by supporting data or information." 4
In that case, the presentence investigator spoke with several residents of Nukapigak's village. The presentence report included the villagers' descriptions of Nukapigak's misconduct.5 Even though the villagers' reports were not based on first-hand knowledge, the supreme court ruled that this information was verified. The villagers were identified in the presentence report, and Nukapigak, who was supplied a copy of the report, was entitled to challenge the accuracy of the reports or offer contrary evidence.6
Here, the probation officer reported that McCoy's father-in-law described a history of domestic violence in the MeCoy home. Included in the report were the father-in-law's description of the difficulties his grandchildren had when in McCoy's home, the grand-childrens' complaints to him, and his description of the domestic violence against his daughter caused by McCoy. The probation officer's source, the father-in-law, is identified and whatever data the father-in-law provided that was not based on his first-hand knowledge was attributed to either his grandchildren or his daughter. Under the rationale of Nukapigak, this constitutes verified information. Therefore, Judge Brown was not required to strike this material from the presentence report.
Whether a presentence imvestigator may review and use the information in a defendant's juvemile probation file without first obtaining special permission from the superior court
McCoy objected to the portion of the presentence report that discussed his contacts with the juvenile justice system (contacts that did not lead to formal adjudications of delinquency). He argued that a presen-tence investigator is not authorized to examine a defendant's juvenile records without first obtaining the superior court's permission.
We first address a subsidiary question of law. When McCoy's attorney argued that the presentence investigator had no authority to use information from MceCoy's juvenile file, the attorney asked Judge Brown to consider one of this Court's memorandum opinions, State v. Westerlin,7 because Chief Judge Bryner's concurring opinion in Wester-lin discusses (but reaches no conclusion regarding) this issue. The State responded by asking Judge Brown to strike McCoy's pleading; the State asserted that the defense attorney had violated Alaska Appellate Rule 214(d), which declares that memorandum de*750cisions of this court are "without precedential effect and may not be cited in the courts of this state."
Black's Law Dictionary defines "cite" "refer to or adduce as precedent or authority."8 MceCoy's attorney did not claim that our memorandum opinion in Westeriin was precedent. It is arguable that the defense attorney adduced Judge Bryner's concurrence as "authority" in the broadest sense of that term-that is, as a record of what another judge thought about a legal issue, for whatever persuasive power it might have. But we do not read Appellate Rule 214(d) to preclude this. Rather, the rule forbids reliance on a memorandum opinion as "authority" in a narrower sense-what Black's Law Dictionary calls "imperative authority": "[a]) legal writing taken as definitive or decisive; esplecially], a judicial ... decision cited as precedent." 9
McCoy's attorney did not claim or imply that our unpublished decision in Westeriin resolved the issue of statutory interpretation presented in McCoy's case or that it restricted the seope of Judge Brown's decision-making authority on this issue. Thus, the defense attorney did not violate Appellate Rule 214(d) by bringing Westerlin to Judge Brown's attention.
We now turn to the merits of McCoy's argument. McCoy concedes that Alaska Criminal Rule 32.1(b)(1) specifically requires presentence reports to include "any finding of delinquency." But MceCoy contends that prior judicial approval is needed before a presentence Investlgator can refer to any other aspect of a defendant's juvenile history-i.e., contacts that did not lead to a formal delinquency adjudication. To support this contention, McCoy relies on a statute, AS 47.12.300, and a. court rule, Alaska Delinquency Rule 27(a)(1).
Alaska Statute 47.12.300(d) states that the superior court is required to seal "all the court's official yecords pertaining to [a] minor" within 30 days of the time the court relinquishes juvenile jurisdiction over the minor (normally, at the time of the minor's 18th birthday). The statute then declares that, once these official court records are sealed, "[no] person may ... use these ... records for any purpose except that the court may order their use for good cause shown or may order their use by an officer of the court in making a presentenc[e] report."
In fact, not only does section 300(d) seemingly prohibit the presentence investigator from "using" the juvenile records without a court order, but section 800(e) seemingly prevents the presentence investigator from even looking at these records. Section 800(e) declares that the records "may be inspected only with the court's permission and only by persons having a legitimate interest in them."
McCoy also relies on Alaska Delinquency Rule 27(a)(1), but this rule appears to authorize the practice McCoy is challenging. Delinquency Rule 27(a)(1) states in pertinent part:
The court records of a juvenile delinquency proceeding are confidential.... Information [concerning those court records] may not be released and access to the records may not be permitted except as authorized by statute 'or upon court order for good cause shown, ... except that ... [a] probation officer employed by the [State of Alaska] may review delinquency proceedings records for the sole purpose of preparing a presentence report on the individual whose juvenile record is reviewed. The records may be used in the sentencing proceeding and attached to the probation officer's report.
Nevertheless, McCoy argues that this rule supports his position. He points out that the rule speaks of a probation officer's authority to review "delinquency proceedings records" when preparing a presentence report. McCoy contends that this phrase encompasses only "official court records" of the juvenile proceeding. By this, he means that Rule 2T7(a)(1) covers the court's records of the proceedings held in a juvenile case but not the material contained in the juvenile probation officer's file (unless that material hap*751pens to be incorporated into a court pleading or order). To gain access to the material in the juvenile probation officer's file, MeCoy argues, a presentence investigator must formally seek and obtain the superior court's permission.
The problem with McCoy's suggested interpretation of Rule 27(a)(1) is that it would leave the juvenile probation officer's file unprotected. As stated in the first sentence of Rule 27(a), the purpose of the rule is to establish the confidentiality of "[the court records of a juvenile delinquency proceeding"-a phrase which we construe to be equivalent to "delinquency proceedings records" (the shorter phrase used later in that same paragraph). If, as McCoy argues, these two phrases refer only to the papers in the superior court's file, then there would be no rule to protect the confidentiality of the juvenile probation officer's file.
Moreover, under MeCoy's interpretation, AS 47.12.300 would not protect the contents of the juvenile probation officer's file, either. That statute requires the sealing of "all the court's official records pertaining to [a] minor." If, as McCoy suggests, "the court's official records" do not include the juvenile probation officer's file, then the statute likewise offers no protection to that file.
Because McCoy's interpretation leads to results that are inconsistent with the protective goals shared by the legislature and the supreme court, we reject his interpretation.10 Instead, we construe the phrases used in Delinquency Rule 27(a)-"court records of a juvenile delinquency proceeding" and "delinquency proceedings records"-to include the contents of the juvenile probation officer's file. Similarly, we conclude that the phrase used in AS 47.12.300(d)-"the court's official records pertaining to [a) minor"-likewise encompasses the juvenile probation officer's file.
We must next address the differences between AS 47.12.300 and Delinquency Rule 27(a)(1). Under AS 47.12.300, a presentence investigator must secure special permission from the superior court before inspecting and using juvenile records. But under Delinquency Rule 27(a)(1), a presentence investigator is automatically entitled to inspect and use these records for the purpose of preparing an adult presentence report on that individual.
We resolve this conflict by noting that the difference is one of procedure. Both the statute and the rule allow a presentence investigator to review juvenile records. However, AS 47.12.300 requires the presentence investigator to obtain special permission from the superior court in each separate case, while Delinquency Rule 27(a)(1) allows the presentence investigator to review the records without obtaining prior case-specific approval from the superior court. In such instances, the procedure specified in the court rule takes precedence over any contrary procedure specified in the statute.11
We therefore hold that a presentence investigator in an adult criminal case may review and use the materials found in the defendant's juvenile court files (including the juvenile probation officer's files) without first obtaining case-specific permission from the superior court. Judge Brown acted correctly when he denied McCoy's motion to strike this information from McCoy's presentence report.
Conclusion
OPINION DENYING REHEARING
Christopher McCoy asks us to reconsider our decision in his appeal, McCoy v. State, 59 P.3d 747 (2002).
McCoy's main contention on appeal was that pre-sentence investigators must obtain *752case-specific authorization from the superior court before they can examine a defendant's juvenile probation files and before they can refer to a defendant's criminal activities as a juvenile if those eriminal activities were "adjusted" informally and did not lead to a formal adjudication of delinqueney. To support this contention, McCoy relied on a court rule, Alaska Delinquency Rule 27(2)(1), and a statute, AS 47.12.300. In our decision, we rejected McCoy's interpretations of this court rule and this statute, and we held that pre-sen-tence investigators do not need to obtain case-specific court permission before they refer to a defendant's non-adjudicated acts of delinquency. McCoy, opinion at page 751.
McCoy now seeks rehearing. He asserts that we should reconsider our ruling because we failed to consider another statute, AS 122.47.810(a). This statute declares that "all information and social records pertaining to a minor who is [alleged to have committed delinquent acts] prepared by or in the possession of a federal, state, or municipal agency or employee ... are privileged and may not be disclosed directly or, indirectly to anyone without a court order."
McCoy contends that even if Delinquency Rule 27(a) and AS 12.47.8300 do not support his argument on appeal, his argument is nevertheless correct because this other statute-AS 12.47.310(a)-forbids a pre-sentence investigator from obtaining information relating to a defendant's acts of delinquency if those acts did not lead to a formal adjudication of delinquency.
McCoy did not cite AS 12.47.810(a) in either of his briefs to this Court. This omission would normally preclude McCoy from seeking rehearing on this point. As we said in Booth v. State, "[Appellate] Rule 506(a) was not intended to allow parties to raise new arguments after they have had a chance to analyze an appellate court's decision. Rule 506(a) implicitly limits rehearing to legal principles or propositions that were raised by the parties in the normal course of the appeal." 1
McCoy points out that he did mention AS 1247.310(a) in his trial court pleading, and that this pleading was included in his excerpt of record on appeal. But the fact that an argument may be mentioned in a defendant's trial court pleadings does not preserve the argument for appeal. A party's briefs must contain the factual and legal arguments that the party wishes the appellate court to consider: A party 'may not argue a point by incorporating trial court pleadings by reference.2 Much less can a party "argue" a point by designating trial court pleadings for inclusion in the excerpt of record without even alerting the appellate court that the party intends to rely on the arguments presented in those trial court pleadings.
McCoy asserts that his failure to mention AS 47.12.310(a) in his briefs to this Court must have been due to "typographical error or oversight on the part of defense counsel". We reject McCoy's contention of "typographical error", And a petition for rehearing is not the proper vehicle for addressing McCoy's claim of attorney negligence.
Moreover, AS 47.12.310(a2) does not provide a clear and straightforward answer to the legal contention raised in McCoy's appeal. Even though the statute declares that "all information and social records pertaining to a minor ... are privileged and may not be disclosed directly or indirectly to anyone without a court order", the statute also declares that this rule of privilege is subject to numerous exceptions-in particular, the exceptions specified in AS 47.12.810(b)-(g), AS 47.12.315, and AS 47.12.3820.
Many of the exceptions listed in AS 47.12.310(b)-(g) appear to undereut McCoy's contention that a pre-sentence report can not refer to unadjudicated acts of delinquency. For example, AS 47.12.310(b)(1) states that a minor's records "shall" be disclosed to a federal, state, or municipal law enforcement agency when those records are pertinent to a specific investigation being conducted by that agency. - Further, AS 4712.810(b0)@)(E) states that a minor's records "shall" be dis*753closed to "a law enforcement agency of this state or another jurisdiction as may be necessary for the protection, rehabilitation, or supervision of any minor or for actions by that agency to protect the public safety". Other provisions of AS 47.12.8310 also conceivably allow disclosure to a pre-sentence investigator: - see AS 47.12810(c)(d4) and AS 47.12.3108).
Turning to AS 47.12.315, for all acts of delinquency committed on or after January 1, 1998 3, subsection (a)(1) of this statute specifically authorizes disclosure of all information relating to a minor's acts of delinquency (except the name of the victim) "when an ageney takes action under AS 47.12.040(a)(1) to [informally] adjust a [delinquency] matter" and the matter involves a crime against a person punishable as a felony, or arson, burglary, sale of a controlled substance, or any other crime in which the minor employed a deadly weapon. Subsection (b) authorizes these same disclosures whenever the Department of Health and Social Services files a delinquency petition against a minor alleging one or more of these same crimes (apparently without regard to the ultimate disposition of that petition). Subsections (a)(2) and (b)(2) authorize these same disclosures whenever a delinquent act has been informally adjusted and the minor then fails to comply with the conditions of the adjustment.
Finally, turning to the third statute, AS 47.12.8320, subsection (a)(2) states that the Department of Health and Social Services "may disclose confidential or privileged information about the minor and make available for inspection documents about the minor" to the Governor, the Lieutenant Governor, any legislator, the state Ombudsman, the Attorney General, the Commissioner of Health and Social Services, the Commissioner of Administration, the Commissioner of Public Safety, and any person working for them "for review or use in their official capacities".
We need not-and do not-definitely construe any of these statutory provisions. Our point is that, contrary to McCoy's argument in his petition for rehearing, AS 47.12.310(@) does not clearly and unambiguously state that a pre-sentence investigator is barred from examining or relying on Department of Health and Social Services records pertaining to a defendant's prior acts of delinquency when those acts were informally adjusted. In fact, when the four pertinent statutes-AS 47.12.8300 through 320-are considered together, it appears that the law is the opposite of what McCoy claims it to be.
For these reasons, McCoy's petition for rehearing is DENIED.
