Supreme Court Declines to Overturn Juvenile’s Guilty Plea

---

Saipan, CNMI – In In re Commonwealth (R.J.K.S.), the Supreme Court affirmed the juvenile court’s acceptance of a guilty plea of a sixteen-year-old defendant to second-degree murder, assault with a dangerous weapon, and aggravated assault and battery. The defendant pled guilty before the preliminary hearing. The Commonwealth objected, stating it had intended to seek the court’s permission to proceed against the defendant in an adult criminal proceeding. The juvenile court established the defendant understood the consequences of pleading guilty and the rights he was waiving, then accepted the plea and adjudicated the defendant on all three counts. It then found the motion to waive jurisdiction moot.

The Commonwealth sought a writ of mandamus, which requires a clear error of law. The Commonwealth identified five potential reasons to find the acceptance of the guilty plea a clear error: (1) the Juvenile Justice Act automatically transferred juvenile court jurisdiction of certain enumerated offenses, including second-degree murder; (2) the waiver motion had yet to be resolved; (3) the admissions did not comply with Rule 11 of the Rules of Criminal Procedure; (4) the adjudication violated due process and separation of powers; and (5) the adjudication violated the Victim’s Bill of Rights.

The Supreme Court considered and rejected each of these arguments. It found it plausible that the Juvenile Justice Act required a judicial process to transfer jurisdiction, rather than jurisdiction being automatically divested. It is also within a court’s discretion to decide in the order in which it addresses the matters before it. Likewise, Rule 11 requires only that a guilty plea is voluntary; a defendant pleading guilty quickly does not unequivocally mean the plea was involuntary. Both constitutional arguments failed: the prosecution could not raise the defendant’s due process claims and acceptance of a guilty plea before deciding another motion was a judicial function, not an interference with an executive one. Finally, the Victim’s Bill of Rights assigns the relevant responsibilities to executive branch officials rather than to the judiciary. The juvenile court did not clearly misinterpret or violate any legal requirement, and mandamus relief was unavailable.
