SLIP OPINION Cite as: 2026 MP 8 Decided August 18, 2026 CHIEF JUSTICE ALEXANDRO C. CASTRO ASSOCIATE JUSTICE JOHN A. MANGLOÑA JUSTICE PRO TEMPORE KATHERINE A. MARAMAN Juvenile Case No. 25-0010 Associate Judge Lillian Ada Tenorio, Presiding In re Commonwealth, 2026 MP 8

CASTRO, C.J.: ¶1 The Commonwealth petitions for a writ of mandamus, seeking to vacate the adjudication of delinquency and order denying waiver of jurisdiction in a juvenile case. It argues that the Juvenile Justice Act (“JJA”) divested the juvenile court of the authority to proceed once R.J.K.S. was charged with second-degree murder and other enumerated offenses, or, at the very least, once the Commonwealth filed its motion to transfer the case for adult criminal prosecution. Mandamus is appropriate only when the trial court acts in clear contravention of unambiguous law. Because the court’s actions were consistent with plausible interpretations of the JJA, its exercise of jurisdiction cannot be characterized as clear error. We therefore DENY the petition.

I. FACTS AND PROCEDURAL HISTORY ¶2 In July 2025, the Commonwealth filed a criminal complaint and declaration of probable cause alleging that R.J.K.S., then sixteen years old, fatally injured his grandmother by repeatedly striking her with an aerosol can.

The declaration summarized witness statements, physical evidence recovered from the residence, and preliminary medical findings. An arrest warrant issued shortly thereafter, and R.J.K.S. was taken into custody and transported to the Juvenile Detention Unit.

¶3 During the bail hearing, the prosecution emphasized the seriousness of the charges and stated its intention to prosecute R.J.K.S. as an adult. The court set bail at $200,000 cash, appointed counsel, and scheduled the case for preliminary hearing and arraignment.

¶4 The case did not proceed to a hearing immediately. Over the next two weeks, several appointed attorneys moved to withdraw due to conflicts of interest. As new counsel was appointed and additional conflicts arose, the scheduled proceedings were continued to ensure that R.J.K.S. was represented by conflict-free counsel.

¶5 After newly appointed counsel accepted representation, the Commonwealth filed a Complaint of Delinquency pursuant to the JJA. The pleading invoked the jurisdiction of the Superior Court sitting as a juvenile court and alleged that R.J.K.S. was delinquent based on conduct that, if committed by an adult, would constitute second-degree murder, assault with a dangerous weapon, and aggravated assault and battery.

¶6 Proceedings resumed with R.J.K.S. appearing alongside counsel; his mother was also present. Defense counsel waived the preliminary hearing and stated that R.J.K.S. wished to proceed directly to arraignment and admit the allegations set forth in the Complaint.

¶7 The Commonwealth objected, stating on the record that it intended to file a motion seeking waiver of juvenile jurisdiction and transfer to adult criminal proceedings. This unusual procedural posture prompted a recess. During that In re Commonwealth, 2026 MP 8 recess, the Commonwealth filed a written motion seeking waiver of juvenile jurisdiction under 6 CMC § 5124(b). 1 ¶8 When proceedings resumed that afternoon, the prosecution renewed its objection and noted that the transfer motion had been filed during the recess. It again urged the resolution of the waiver issue before proceeding with arraignment.

¶9 The case proceeded to arraignment. After being placed under oath, R.J.K.S. was advised of the charges and informed that each offense carried a maximum detention period of one year under the JJA. He was also advised of his constitutional rights, including the right to remain silent, the right to require the Commonwealth to prove the allegations beyond a reasonable doubt, and the right to confront and cross-examine witnesses, the right to present evidence, and the right to proceed to trial.

¶ 10 R.J.K.S. stated that he understood those rights and wished to waive them.

He also confirmed that he had sufficient time to consult with counsel, that he was satisfied with counsel’s representation, and that no threats or promises had induced his admissions. When asked whether the allegations contained in the Complaint of Delinquency were true, he answered in the affirmative.

¶ 11 Based on these responses and the factual record before it, the court accepted the admissions and adjudicated R.J.K.S. delinquent on all three counts.

¶ 12 The Commonwealth again objected and requested a ruling of its pending motion to waive jurisdiction. Rather than address the motion at that time, the court scheduled the matter for disposition and ordered the preparation of a pre- disposition investigation report. A written Adjudication of Delinquency issued the following day. Several days later, the court denied the Commonwealth’s motion to waive jurisdiction as moot.

¶ 13 The Commonwealth filed the present petition for a writ of mandamus challenging the adjudication and the denial of its motion to waive jurisdiction.

II. JURISDICTION ¶ 14 Article IV, Section 3 of the NMI Constitution and 1 CMC § 3102(b) vest this Court with original jurisdiction to issue writs of mandamus.

III. STANDARD OF REVIEW ¶ 15 A petition for a writ of mandamus is reviewed under five factors: whether (1) no other adequate means exist to obtain the requested relief; (2) the petitioner will suffer damage or prejudice not correctable on appeal; (3) the challenged order is clearly erroneous as a matter of law; (4) the order reflects an oft-repeated error or persistent disregard of applicable rules; and (5) the order raises new and In re Commonwealth, 2026 MP 8 important problems or issues of first impression. In re Commonwealth, 2016 MP 8 ¶ 8 (citing Commonwealth v. Superior Ct., 2004 MP 14 ¶ 7). Not all five factors must be satisfied, but the third is dispositive. A writ will not issue absent a showing of clear error. Commonwealth v. Commonwealth Utils. Corp., 2014 MP 21 ¶ 9.

IV. DISCUSSION ¶ 16 Mandamus occupies a narrow place in judicial review. It is extraordinary relief, “reserved for the most dire of instances.” N. Marianas Hous. Corp. v. Superior Court, 2020 MP 18 ¶ 7. Its function is to confine courts to the jurisdiction and powers conferred upon them and compel performance of duties the law unequivocally requires. Tenorio v. Superior Ct., 1 NMI 1, 7, 9 (1989).

The writ therefore does not reach close questions of statutory interpretation, discretionary procedural rulings, or even ordinary legal error. Those issues belong to ordinary appellate review. Mandamus lies only where a court has clearly usurped power or refused to perform a nondiscretionary duty. In re Abraczinskas, 2023 MP 12 ¶ 6 (quoting Tenorio, 1 NMI at 8–9); Cheney v. United States Dist. Ct., 542 U.S. 367, 375, 380 (2004).

¶ 17 Several considerations nevertheless weigh in favor of mandamus review here. The adjudication is final, and double jeopardy 2 principles bar any renewed prosecution, leaving the Commonwealth without an avenue for ordinary appellate review. The petition also presents unresolved questions concerning the interaction between sections 5124 and 5131 of the JJA. Those considerations satisfy several of the Tenorio factors, but they do not resolve the petition. The decisive question remains whether the rulings below were “so plainly wrong as to indicate failure to comprehend or refusal to be guided by unambiguous provisions of a statute or settled common law doctrine.” Tenorio, 1 NMI at 8.

¶ 18 Against that demanding standard, the Commonwealth emphasizes the gravity of the charge and the significance of the consequences at stake. The underlying offense of second-degree murder is unquestionably serious, and nothing in this analysis diminishes that fact. But gravity of the allegation does not expand jurisdiction, nor does it relax the stringent standard for extraordinary relief. However serious the underlying offense and however unusual the procedural posture, mandamus does not lie unless the Commonwealth demonstrates a plain departure from settled, unambiguous law.

¶ 19 The petition advances five arguments: (1) that jurisdiction automatically divested upon the filing of a charge enumerated in 6 CMC § 5131; (2) that the waiver motion had to be resolved before any admission could be accepted; (3) that the admissions failed to comply with Rule 11 of the NMI Rules of Criminal Procedure; (4) that the adjudication violated due process and separation of powers; and (5) that the adjudication violated the Victims' Bill of Rights. None

In re Commonwealth, 2026 MP 8 establishes the clear and indisputable error required for mandamus relief. We address each argument in turn.

A. Jurisdiction Remained with the Juvenile Court ¶ 20 The petition asserts that jurisdiction ceased once an offense listed in 6 CMC § 5131 was alleged. That argument rests on the premise that the statute automatically divests juvenile jurisdiction at the moment such a charge is filed.

Were the statute properly read that way, mandamus could be warranted. See In re Pangelinan, 2021 MP 11 ¶ 15 (acknowledging any decisions without jurisdiction are “invalid”). However, neither the text, the structure, nor prior precedent clearly supports an interpretation that immediately extinguishes jurisdiction without further judicial action.

1. The Text Is Ambiguous ¶ 21 Mandamus is inappropriate where “a rational and substantial legal argument can be made in support of the questioned jurisdictional ruling.”

Tenorio, 1 NMI at 8. Even an incorrect interpretation of an ambiguous statute does not constitute the clear error that requires extraordinary relief. The inquiry is therefore not which interpretation of sections 5124 and 5131 is ultimately correct, 3 but whether the statutory framework can be reasonably construed to require a hearing before the loss of juvenile jurisdiction.

¶ 22 Section 5131(a) reads: Any juvenile, age sixteen years or age seventeen years, who is alleged to have committed any of the crimes listed in subsection (b) of this section, or any person under age sixteen years who is alleged to have committed any of the crimes listed in subsection (b) of this section and, pursuant to 6 CMC § 5124, has been ordered by the court to be held for adult criminal proceedings shall be proceeded against as an adult.

6 CMC § 5131(a).

¶ 23 The Commonwealth construes this provision to create two categories of juveniles treated differently under the JJA. Under its interpretation, those aged sixteen or seventeen automatically proceed to adult court upon the filing of a qualifying charge, while those under sixteen may be transferred only after a hearing and court order under section 5124. The Commonwealth grounds this reading in the sentence's structure and punctuation: the two age categories are

In re Commonwealth, 2026 MP 8 separated by “or,” and the reference to section 5124 appears only within the clause describing younger juveniles. That interpretation is plausible.

¶ 24 Nevertheless, a reasonable reader could instead understand section 5131(a) as identifying which juveniles may be prosecuted as adults, while leaving section 5124 to govern the transfer process for both groups. The sentence contains a single operative clause, “shall be proceeded against as an adult,” and no language stating that older juveniles bypass transfer procedures or that jurisdiction automatically divests upon the filing of a charge. Under that interpretation, section 5131 defines which juveniles may face adult criminal prosecution, while section 5124 supplies the procedural mechanism. Neither reading is plainly compelled by the wording of section 5131.

¶ 25 The Commonwealth itself acknowledged below that section 5131(a) is “susceptible to two possible plain language interpretations,” and explained that it filed a transfer motion out of an “abundance of caution” because it was “not originally sure” whether a hearing was required. Pet’r’s Br. at 12–13. That ambiguity is fatal to the petition. It places the dispute within the range of reasonable disagreement that mandamus cannot reach.

¶ 26 The relationship between statutory ambiguity and the unavailability of mandamus is well established. In Interstate Commerce Comm’n v. N.Y., N.H. & H.R. Co., the Supreme Court denied the writ where the asserted statutory duty depended upon “doubtful inference from statutes of uncertain meaning.” 287 U.S. 178, 204 (1932). Justice Cardozo explained that when a duty is not “plainly prescribed,” but instead depends upon judicial construction, mandamus is unavailable. Id. ¶ 27 The same principle governs modern mandamus doctrine. In In re Al- Nashiri, the D.C. Circuit explained that open legal questions do not present a clear and indisputable right to mandamus relief. 791 F.3d 71, 85–86 (D.C. Cir. 2015). It follows that where a statute provides two plausible constructions, mandamus cannot be used to decide one reading over another. Whatever the best interpretation of sections 5124 and 5131 may be, the statutory scheme lacks the clarity necessary to find clear deviation from settled law.

2. The Structure Reinforces That Ambiguity ¶ 28 In addition to the statutory language, the structure of the JJA does not clearly support the Commonwealth's conclusion. Section 5131 appears in Article 4, titled “Proceedings,” rather than in Article 3, titled “Jurisdiction and Transfers.” A provision automatically terminating juvenile jurisdiction upon the filing of a charge would more naturally appear under Article 3. Its placement instead suggests that section 5131 functions procedurally rather than as a self- executing transfer provision. See Saipan Achugao Resort Members’ Ass’n v. Wan Jin Yoon, 2011 MP 12 ¶ 23 (stating that when “determining legislative intent, the statute must be read as a whole, and not as isolated words contained therein”).

¶ 29 Moreover, subsection (b) of section 5131 provides those certain offenses “shall result in adult criminal proceedings pursuant to subsection (a).” The In re Commonwealth, 2026 MP 8

Commonwealth argues that this language compels immediate adult prosecution without any intervening judicial process. But subsection (b) functions only “pursuant to subsection (a),” whose meaning is disputed. If subsection (a) contemplates a section 5124 hearing for both age categories, then subsection (b)’s mandatory language establishes the result of that process, not the absence of one.

The statute tells us where the case ends up. It does not clearly specify how it gets there.

¶ 30 Subsection (c) does not clarify that ambiguity. It provides that “[o]nce a juvenile has been transferred for criminal prosecution as an adult pursuant to the waiver provisions of 6 CMC § 5124, or this section,” they shall be held in the adult prison facility. 6 CMC § 5131(c). The Commonwealth reads the phrase “or this section” as recognizing a transfer mechanism distinct from the hearing process under section 5124. But the statute still speaks in terms of a juvenile who “has been transferred,” suggesting a completed legal process rather than immediate divestiture upon the filing of charges alone. Id. ¶ 31 The relationship between sections 5131 and 5124 further undermines the Commonwealth’s interpretation. In part, section 5124 reads: After the filing of a petition and after full investigation and hearing, the court may waive jurisdiction over the juvenile pursuant to this chapter, and order that the juvenile be held for adult criminal proceedings when: (1) A juvenile is alleged to have committed any of the crimes enumerated in 6 CMC § 5131.

6 CMC § 5124(a).

¶ 32 Two features of this language underscore the ambiguity in the statutory scheme. First, section 5124(a) authorizes waiver only “[a]fter the filing of a petition and after full investigation and hearing.” 6 CMC § 5124(a). That sequencing language undermines an automatic divestiture interpretation. Second, subsection (a)(1) contains no age limitation. It does not distinguish between those aged sixteen or seventeen and those under sixteen, referring instead simply to “a juvenile” alleged to have committed a section 5131 offense. The Legislature also demonstrated in section 5131(a) itself that it knew how to distinguish between the two age groups when it intended to do so. The absence of any comparable age qualifier in section 5124(a)(1), together with the statute’s express hearing requirement, at least supports the inference that the waiver provision was not limited solely to juveniles under sixteen.

3. Prior Precedent Applied a Different Statute ¶ 33 Before enactment of the JJA, former 6 CMC § 5103(a) provided that a juvenile sixteen years of age or older “accused of a traffic offense, murder, or rape shall be treated in the same manner as an adult.” Under that scheme, jurisdiction shifted categorically upon the filing of a qualifying charge. No motion was required, no hearing was conducted, and no judicial findings were necessary. See In re N.T.M., 1999 MP 24 ¶ 9 (holding that where a juvenile In re Commonwealth, 2026 MP 8 sixteen or older is charged with an enumerated offense, “the juvenile court is automatically divested of jurisdiction since the offender is subject to the original jurisdiction of the adult criminal court”); Commonwealth v. Repeki, 2004 MP 19 ¶ 10 (relying on In re N.T.M. to hold the same). Those decisions interpreted that statutory framework.

¶ 34 The Legislature fundamentally altered that framework when it enacted the Juvenile Justice Act through Public Law 16-47. The JJA repealed former section 5103(a) in its entirety and replaced the prior categorical scheme with a structured transfer process requiring a written motion, notice, investigation, hearing, and judicial findings before a juvenile may be held for adult criminal proceedings. 6 CMC § 5124(a), (c)–(f).

¶ 35 Those authorities therefore do not control this case. The Legislature knew how to place qualifying juveniles directly within adult criminal jurisdiction because the former statute did exactly that. Where the Legislature knew how to divest jurisdiction automatically, its choice to enact an entirely new transfer provision is best understood as a deliberate departure from the prior scheme, not an inadvertent one. See Salinas v. United States RRB, 592 U.S. 188, 196–97 (2021) (applying the canon that where a legislature includes language in one provision but omits it in another, the omission is presumed deliberate). The JJA’s emphasis on transfer procedure and judicial findings weakens the conclusion that jurisdiction shifts automatically upon the filing of a charge.

¶ 36 The Commonwealth's own conduct in this case reflects similar uncertainty.

The prosecution initiated proceedings in juvenile court, moved to waive jurisdiction under section 5124, and litigated the case on the assumption that jurisdiction remained in place unless and until affirmatively transferred. It now explains those actions as measures taken out of an “abundance of caution.”

Pet’r’s Br. at 12. That explanation underscores the central problem with the petition. Mandamus requires a showing that an order is clearly erroneous as a matter of law. In re Commonwealth, 2016 MP 8 ¶ 8. A party that itself regarded the statute as uncertain enough to warrant caution cannot claim that the juvenile court committed clear and indisputable error by adopting a plausible interpretation.

B. Adjudication Could Proceed Before Resolving the Waiver Motion ¶ 37 The petition alternatively maintains that even if jurisdiction remained, resolution of the waiver motion was required before adjudication could proceed.

It relies principally on United States v. Chambers for the proposition that an adjudication cannot occur while a transfer motion remains pending. 944 F.2d 1253 (6th Cir. 1991).

¶ 38 The Commonwealth’s reliance on Chambers is misplaced. In Chambers, the Sixth Circuit vacated the convictions of juveniles who had been prosecuted directly in adult criminal court without the certification and transfer findings required under the Federal Juvenile Delinquency Act. 944 F.2d at 1257–58. The certification was a prerequisite to the district court’s subject matter jurisdiction In re Commonwealth, 2026 MP 8 over the juvenile defendants. Id. at 1259–60. The Federal Juvenile Delinquency Act’s structure reflects a “legislative perception that accused juvenile offenders generally belong in the hands of state authorities” and Congress therefore intentionally limited the federal jurisdiction over juveniles. Id. at 1258–59.

Limited federal jurisdiction meant the district court lacked the authority to proceed at all until those findings were made. Id. at 1258–59, 1261. The certification requirement was focused on federalism concerns that cannot be waived by any party and not the individual rights of the juvenile. Id. at 1260.

¶ 39 In contrast, the proceedings here were in the local trial court of the Commonwealth and would remain so whether R.J.K.S. was tried as an adult or not. None of the concerns underlining Chambers such as subject-matter jurisdiction or juveniles being ill-served by the federal system are relevant here.

We turn instead to the text of the statute.

¶ 40 Section 5124(a) frames the waiver process in permissive terms: “[a]fter the filing of a petition and after full investigation and hearing, the court may waive jurisdiction over the juvenile pursuant to this chapter.” 6 CMC § 5124(a).

That permissive language does not create a mandatory duty to halt ongoing proceedings. “May” confers discretion; it does not compel action. See United States v. Rodgers, 461 U.S. 677, 706 (1983) (“The word ‘may,’ when used in a statute, usually implies some degree of discretion.”); Commonwealth v. Taisacan, 1999 MP 8 ¶ 7 (explaining discretionary nature of the word “may”). In contrast, subsection (c) dictates a specific procedural obligation: “[u]pon the filing of a motion to waive jurisdiction under this chapter, the court shall enter an order setting the motion for hearing at a reasonable time and date certain.” 6 CMC § 5124(c) (emphasis added). But that obligation extends only to scheduling the hearing itself. Subsection (c) does not require the suspension of all other proceedings while the motion remains pending. The remaining provisions confirm that when the Legislature intended to establish precise procedural duties, it did so expressly, requiring written notice at least thirty days before the hearing, CMC § 5124(d), an evidentiary hearing made part of the record, 6 CMC § 5124(e), and findings of fact and conclusions of law, 6 CMC § 5124(f). None provides that the filing of a waiver motion automatically stays the delinquency proceedings.

¶ 41 When legislatures intend to suspend or control the progression of proceedings, they say so expressly. Vermont’s juvenile delinquency law provides a clear example: “the filing of the motion to transfer jurisdiction shall automatically stay” the time for the preliminary hearing until the motion is resolved. 33 V.S.A. § 5204(b)(1). West Virginia is equally explicit. Upon a juvenile’s direct appeal of a transfer order, “proceedings in criminal court are to be stayed upon motion of the defendant” pending resolution of the appeal. W. Va. Code § 49-4-710(j). The JJA includes no similar stay provision.

¶ 42 In the absence of such limitations, the inherent authority to manage the order and progression of the case remains with the trial court. See Landis v. N.

Am. Co., 299 U.S. 248, 254 (1936) (recognizing “the power inherent in every In re Commonwealth, 2026 MP 8 court to control the disposition of the causes on its docket”); see also Dietz v. Bouldin, 579 U.S. 40, 47 (2016) (acknowledging trial courts’ inherent discretion to manage proceedings to ensure the orderly and efficient resolution of cases).

Consistent with that discretion, Rule 7 of the NMI Rules of Juvenile Delinquency Procedure permits the court to “adopt the procedure it deems best suited to enable it to dispose of the case promptly, justly, and in the best interests of the child and the public, taking care to see the child is not prejudiced by his immaturity or inability to adequately protect his own interests.” NMI R. JUV. P. 7.

¶ 43 The procedural history here illustrates the operation of that authority in practice. The Commonwealth did not file its written motion to waive jurisdiction until 1:33 p.m. on August 13. By that point, the order continuing arraignment to 3:00 p.m. had already issued. The motion was nevertheless filed, repeated objections concerning transfer were heard during the afternoon proceedings, and its position was expressly acknowledged on the record. Rather than refusing to entertain the waiver request, the court proceeded with arraignment and later issued a written order explaining why it concluded the motion had become moot following adjudication.

¶ 44 A motion to waive jurisdiction under section 5124 presupposes a live controversy. By the time the waiver motion was addressed, R.J.K.S. had been adjudicated delinquent on all three counts, jeopardy had attached, and the JJA provided no mechanism to undo that result and resume transfer proceedings.

Denying the motion as moot was not a refusal to perform a clear legal duty; it was recognition that no such duty remained. See Govendo v. Micronesian Garment Mfg., Inc., 2 NMI 270, 281 (1991) (stating that courts lack jurisdiction to decide moot cases). Treating the motion as moot after adjudication did not constitute a clear usurpation of authority.

C. The Admissions of Guilt Satisfied Rule 11 ¶ 45 Rule 11 of the Commonwealth Rules of Criminal Procedure exists to ensure that the accused understands the nature of the charges, the rights being surrendered, and the consequences of the decision to plead guilty. Compare COM.

R. CRIM. P. 11 with Brady v. United States, 397 U.S. 742, 748 (1970). The question here is whether R.J.K.S. actually comprehended what he was admitting to and chose to proceed freely and intelligently. Consistent with that purpose, Rule 11 does not require reversal for every procedural imperfection. Relief is warranted only where an alleged defect affects substantial rights. See COM. R. CRIM. P. 11(h) (“any variance from the procedure required by this rule which does not affect substantial rights shall be disregarded”). 4 On this record, the Commonwealth has shown no such error.

In re Commonwealth, 2026 MP 8

1. The Admissions were Voluntary and Intelligent ¶ 46 Rule 11(d) provides that the court “shall not accept a plea of guilty or nolo contendere without first, by addressing the defendant personally in open court, determining that the plea is voluntary and not the result of force or threats or of promises apart from a plea agreement.” COM. R. CRIM. P. 11(d). A plea satisfies constitutional requirements where it represents “a voluntary and intelligent choice among the alternative courses of action open to the defendant.”

Commonwealth v. Cabrera, 2 NMI 311, 317 (1991) (quoting North Carolina v. Alford, 400 U.S. 25, 31 (1970)).

¶ 47 Involuntariness exists where threats or coercive pressure overbear the defendant’s will. Brady, 397 at 750. The Commonwealth identifies no such conduct here. Instead, it relies primarily on the speed of the proceedings and the recent appointment of counsel. Those circumstances, however, do not render an admission involuntary. A defendant who elects to plead after weighing available options with the assistance of counsel enters a voluntary plea, even where that decision is made promptly or motivated in part by a desire to limit exposure. Id. at 749–50; see also Commonwealth v. Sablan, 2020 MP 11 ¶ 5 (explaining that sentencing concessions, even if they induce a guilty plea, do not render the plea involuntary).

¶ 48 Rule 11(c) requires assurance that the defendant understands the nature of the charges and the consequences of the plea before an admission may be accepted. COM. R. CRIM. P. 11(c). Consistent with those requirements, proceedings resumed at 3:00 p.m. on August 13, 2025, with R.J.K.S. placed under oath and personally informed of the rights he would waive by entering admissions. App. at 92–97. The charges and penalties were explained, including that the “maximum detention period” for each offense was “one year.” App. 93– 94. The court advised R.J.K.S. of “the right to remain silent,” that “anything you say can be used against you,” and “the right to confront witnesses against you.”

App. 95–96. R.J.K.S. was further informed that admissions would waive “your right to a bench trial.” App. 96. He confirmed that he understood each right and wished to waive it. Id. ¶ 49 The inquiry then turned directly to voluntariness. R.J.K.S. confirmed that he was “satisfied with the services of your attorney.” Id. When asked, “Are you sure?” R.J.K.S. responded, “I am sure.” Id. at 97. The court accepted the admissions only after those exchanges. The Commonwealth’s suggestion that the advisement of rights occurred after acceptance of the admissions inverts the sequence reflected in the transcript. Rather, the court's closing statement that acceptance rested on “your admission, the factual basis, [and] your understanding

(reaffirming that Rule 11 errors warrant relief only where they affect substantial rights).

The Commonwealth Rule of Criminal Procedure 11 tracks the federal rule in all relevant respects, and the reasoning of those decisions is persuasive authority here. See Claassens v. Rota Health Ctr., 2021 MP 9 ¶ 13 n.6. In particular, Rule 11(h) of the Rules of Criminal Procedure is identical to its federal counterpart.

In re Commonwealth, 2026 MP 8 your rights and waiving them” confirms the colloquy preceded acceptance. App. 97.

¶ 50 R.J.K.S.’s representation by counsel further demonstrates that the admissions were deliberate and informed. Counsel was appointed on August 12, 2025, and appeared with R.J.K.S. the following morning. App. at 40, 87. Before any admissions were entered, counsel represented on the record that he had “reviewed the charges with the defendant” and had “also advised him of all his rights.” Id. at 87. Nothing in the record suggests confusion, hesitation, coercion, or disagreement between counsel and client. Although the admission was made quickly, Rule 11 does not require a minimum consultation period with counsel before an admission may be accepted. The decisive inquiry is whether R.J.K.S. understood the rights being waived and voluntarily chose to proceed. There was a sufficient basis here to conclude that he did.

2. The Factual Basis Was Adequate ¶ 51 Rule 11(f) provides that the court “should not enter a judgment upon such plea without making such inquiry as shall satisfy it that there is a factual basis for the plea.” COM. R. CRIM. P. 11(f). That provision calls for the exercise of judicial judgment, not adherence to a prescribed script. United States v. Mancinas-Flores, 588 F.3d 677, 682 (9th Cir. 2009). A court “need not rely on the plea colloquy alone and ‘may conclude that a factual basis exists from anything that appears on the record.’” Id. (quoting United States v. Mastrapa, 509 F.3d 652, 660 (4th Cir. 2007)).

¶ 52 That standard was satisfied here. The Complaint of Delinquency and accompanying Declaration of Probable Cause set out detailed factual allegations supporting each charged offense. The complaint described that investigators recovered evidence showing R.J.K.S. repeatedly struck the victim in the face with an “19 oz. Lysol can,” causing “facial fracture[s], lacerations, and a ruptured right eye,” which in turn produced traumatic brain injury resulting in death. App. at 43–44. The complaint further identified the specific offenses charged and described conduct corresponding to each offense. Id. ¶ 53 R.J.K.S. was asked directly: “Are you pleading guilty because you are, in fact, guilty . . . you are admitting these facts because in fact you did these things.”

App. 97. R.J.K.S. answered: “Yes, Your Honor.” Id. The colloquy continued with the court asking again, “You, in fact, did them. That's why you are admitting the charges.” Id. R.J.K.S. confirmed: “Yes, I am.” Id. ¶ 54 No actual deficiency in that factual basis has been identified. The Commonwealth does not contend that the allegations failed to establish causation, intent, use of a dangerous weapon, bodily injury, or any other statutory element of the charged offenses. Instead, its objection rests almost entirely on procedure, namely, that the government did not orally recite a narrative statement of facts during the colloquy itself. Rule 11(f), however, prescribes no such requirement. Taken together, the charging documents and R.J.K.S.’s admissions provided an adequate factual basis for the plea.

In re Commonwealth, 2026 MP 8

D. The Commonwealth's Constitutional Claims Are Without Merit 1. The Due Process Clause Does Not Run in Favor of the Prosecution ¶ 55 Procedural due process applies when governmental action threatens to deprive a person of a protected interest in life, liberty, or property. No such deprivation is identified here. The due process claim rests entirely on the premise that the JJA statutorily required resolution of the transfer motion before any further adjudication. As explained above, the JJA does not clearly prescribe such a requirement. The constitutional claim rises and falls with the statutory one.

¶ 56 The Commonwealth attempts to sidestep this threshold problem by recasting the claim as one on R.J.K.S.’s behalf, arguing that R.J.K.S.’s own due process rights required resolution of the transfer motion before his admissions could be accepted. That reframing fails. The Commonwealth contends that proceeding to adjudication prejudiced R.J.K.S., yet seeks to vacate that adjudication so that R.J.K.S. may instead face adult prosecution. The decision to appeal a violation of the defendant’s due process right is a question of legal strategy for him to decide with the assistance of his own legal counsel. See United States v. Sineneng-Smith, 590 U.S. 371, 375–76 (2020) (discussing how in an adversarial system, the general rule is that parties with competent counsel are responsible for advancing their own interests). A due process argument premised on protecting the juvenile cannot rob him of his right to manage his own defense and risk the outcome most adverse to him.

2. The Prosecution Cannot Use Separation of Powers to Halt Judicial Proceedings ¶ 57 That the executive branch controls charging decisions, including whether to seek adult prosecution, does not mean it controls the sequencing of proceedings once a case is properly before a court. Decisions about what motions remain pending and when adjudication may proceed are judicial functions. The Commonwealth had every right to move for transfer under section 5124. But the filing of that motion did not create a constitutional or procedural entitlement to suspend the proceedings pending its resolution.

¶ 58 In United States v. Nixon, the President argued that separation of powers shielded executive communications from a judicial subpoena. The Court rejected that claim, holding that even within its own constitutional domain the executive branch cannot use separation of powers as an absolute block to a legitimate exercise of judicial authority. 418 U.S. 683, 703–07 (1974). Just as the executive cannot invoke separation of powers to override the power to compel evidence, the executive cannot invoke it to override the power to manage proceedings already before it. The Commonwealth’s right to seek transfer does not give it the power to dictate when and how the court acts on what is already on its docket.

¶ 59 Accepting that position would allow a prosecutor to halt judicial proceedings at any moment simply by filing a motion. However, preserving the court's independence to manage its own docket and determine what controversies remain live is itself a structural constitutional value. Cf. Landis v. N. Am. Co., 299 U.S. 248, 254 (1936) (noting that trial courts possess inherent authority to In re Commonwealth, 2026 MP 8 manage proceedings to ensure their orderly and efficient resolution); Dietz v. Bouldin, 579 U.S. 40, 47 (2016) (same). The Commonwealth’s constitutional claims therefore fail for the same reason as its statutory ones. What occurred here was not a usurpation of executive power but an exercise of judicial authority.

Accordingly, there was no clear error.

E. The Victims' Bill of Rights Imposed No Duty on the Judiciary ¶ 60 The Commonwealth also argues the proceedings violated the Victims’ Bill of Rights because the victim’s family allegedly was not provided notice or an opportunity to be heard. That argument is unpersuasive. The statute imposes duties only on “officers and employees” of agencies involved in the “detection, investigation, or prosecution of crime”; it does not impose a corresponding obligation on the judiciary. 6 CMC § 9104(a). The statutory notice requirements therefore apply to investigative and prosecutorial agencies, not to the court itself.

¶ 61 Moreover, Section 9104(c) confirms that compliance with the statute’s notice provisions is not a prerequisite to the validity of proceedings. Any failure to notify the victim’s family therefore is attributable to the prosecution or responsible agencies and would not invalidate the proceedings.

V. CONCLUSION ¶ 62 The Juvenile Justice Act does not clearly or unequivocably compel the result the Commonwealth seeks. At most, the petition raises a disputable question of statutory interpretation. Mandamus is not available to resolve reasonable disputes over statutory interpretation, as it is reserved for correcting clear and indisputable legal error. Because the Commonwealth has not shown that the trial court violated a plainly defined and mandatory legal duty, or otherwise acted beyond its jurisdiction, mandamus relief is unwarranted. The petition is therefore DENIED.
