in Re: Jamar M., a Minor

court. The court also appears to have determined that NRS 62B.330(3)(e)(1) divested it of jurisdiction over the offenses that allegedly occurred when J.M. was 16 years of age. J.M. first challenges the juvenile court's determination that NRS 62B.330(3)(e)(1) applied and divested it of jurisdiction. J.M. contends that the statute does not apply because the State cannot establish that he was 16 years old during the relevant time period. 2 We disagree. NRS 62B.330(3)(e)(1) divests the juvenile court of jurisdiction over a person who is charged with committing an offense that would have been a category A or B felony if committed by an adult when he or she was between the ages of 16 and 18 and who is identified and charged between the ages of 20 years, 3 months and 21 years. In re George J., 128 Nev. , f 279 P.3d 187, 188, 191 (2012). The statute contains no requirement that the State prove the offender's age at the time of the offense. Compare NRS 62B.330(3)(e)(1) (divesting the juvenile court of jurisdiction over certain persons charged with certain offenses), with NRS 62B.335(2) (requiring the juvenile court to determine whether probable cause supports charges before considering whether to transfer a person for criminal proceedings). Therefore, J.M.'s contention that NRS 62B.330(3)(e)(1) does not apply because the State cannot establish his age at the time of the offense lacks merit. J.M. also asserts that NRS 62B.335 does not apply to him. The 2 juvenile court specifically concluded that NRS 62B.335 did not apply. 2 J.M. next contends that because neither NRS 62B.330(3)(e)(1) nor NRS 62B.335(1) address which court has jurisdiction over a person who committed offenses when he or she was under the age of 16, and he was under the age of 16 for part of the time period charged, the juvenile court retained jurisdiction over the offenses. This contention lacks merit. "'[T]he juvenile court system is a creation of statute, and it possesses only the jurisdiction expressly provided for it in the statute." State v. Barren, 128 Nev. „ 279 P.3d 182, 184 (2012) (quoting Kell v. State, 96 Nev. 791, 792-93, 618 P.2d 350, 351 (1980)). J.M. does not assert that any statute grants the juvenile court jurisdiction over him. And he does not dispute the juvenile court's conclusion that it lacked jurisdiction because J.M. is over the age of 21. See NRS 62B.330(1) ("[T]he juvenile court has exclusive original jurisdiction over a child living or found within the county who is alleged or adjudicated to have committed a delinquent act."); NRS 62A.030(1) (defining the term "child" to exclude persons over the age of 21 unless circumstances not relevant here apply); see also NRS 62B.410(2) (juvenile court jurisdiction ends when a child turns 21 years old). Because the district court has jurisdiction over a defendant where the juvenile court does not, Barren, 128 Nev. at , 279 P.3d at 184, (barring exceptions that are inapplicable here, "some court always has jurisdiction over a criminal defendant"), J.M. fails to demonstrate that the juvenile court erred by transferring his case for criminal proceedings. Finally, J.M. contends that because the writ of attachment "arguably" expired on his 21st birthday but he was not arrested until after he turned 21 years old, the case must be dismissed. We decline to address SUPREME COURT OF NEVADA 3 (0) I947A this contention because it is not supported by any argument or citation to authority. See Maresca v. State, 103 Nev. 669, 673, 748 P.2d 3, 6 (1987). Having determined that J.M. is not entitled to relief, we ORDER the judgment of the juvenile court AFFIRMED. 3 Hardesty cc: Hon. William 0.
