OPINION

By the Court, HERNDON, C.J.:

The rules of civil procedure govern court-ordered mental and physical examinations of a party for purposes of litigation. See NRCP 35(a). In 2021, we ruled that a statute governing the same, NRS 52.380, unconstitutionally encroached on the inherent power of the judiciary to regulate court procedures. Lyft, Inc. v. Eighth Jud. Dist. Ct., 137 Nev. 832, 501 P.3d 994 (2021). In response, the legislature enacted NRS 629.620, which applies to persons required to undergo a mental or physical examination by court order, contractual obligation, or some other obligation. Like its predecessor, NRS 629.620 permits exam conditions that directly contradict those addressed in NRCP 35. In this writ proceeding, petitioner challenges a district court order directing the plaintiff in civil litigation to comply with an examination subject to conditions beyond or contradictory to those set forth in NRCP 35 but arguably allowed by NRS 629.620. We hold that NRS 629.620 violates the separation of powers doctrine to the extent that it imposes conditions that conflict with or exceed those that NRCP 35 establishes for court-ordered independent medical or physical examinations during discovery. Therefore, to the extent NRS 629.620 applies to NRCP 35-based exarninations in civil discovery, it is SUPREME COURT OF NEVADA

40) 1947A 44D ,1, unconstitutional and of no effect. As to the specific conditions challenged here, the district court did not abuse its discretion in permitting the disclosure of the raw testing data to counsel but did abuse its discretion in allowing for the presence of an interpreter and in allowing the exam to be audio recorded. Therefore, the writ petition is granted in part.

FACTS AND PROCEDURAL HISTORY Petitioner Gabriel Powers and real party in interest Carlos Patino Bueno were involved in a motor vehicle collision. Bueno sued, claiming to have suffered a traumatic brain injury and seeking nearly $2 million in damages related to the injury. The parties agreed that Bueno would undergo a neuropsychological exam but could not agree on the

conditions to be imposed on the exam. Powers argued that the exam was subject to the requirements under NRCP 35, while Bueno argued that it was subject to the requirements under NRS 629.620. The district court expressly ruled that the exam was subject to the requirements of NRCP 35 and then imposed the following conditions: (1) the raw data from the exam was to be provided to Bueno's counsel and others involved in the litigation with reasonable restrictions involving disclosure; (2) the data could be

examined by counsel and by an expert in a different field; (3) Bueno is not required to obtain an expert to access the raw data; (4) an observer would not be present, but the exam would be audio recorded; and (5) Bueno would have the assistance of a court-certified interpreter for the entirety of the exam. These conditions exceeded, in part, the scope of NRCP 35 and, at times, seemingly invoked the intent of the legislature and NRS 629.620. Powers sought reconsideration, which the district court denied. This writ petition followed.

DISCUSSION

We elect to entertain the petition A writ of mandamus or prohibition is an extraordinary remedy, and "[t]he decision to entertain a petition for [writ relief] lies within this court's discretion." Gen. Motors Corp. v. Eighth Jud. Dist. Ct., 122 Nev. 466,

469, 134 P.3d 111, 113-14 (2006). A writ of mandamus is available to compel the performance of an act that the law requires or to control an arbitrary or capricious exercise of discretion. NRS 34.160; Int'l Garne Tech., Inc. v. Second Jud. Dist. Ct., 124 Nev. 193, 197, 179 P.3d 556, 558 (2008). And prohibition may issue "to arrest the proceedings of a district court exercising its judicial functions when such proceedings are in excess of the jurisdiction

of the district court." Club Vista Fin. Servs. v. Eighth Ad. Dist. Ct., 128 Nev. 224, 228, 276 P.3d 246, 249 (2012).

Though a plain, speedy, and adequate legal remedy ordinarily precludes writ relief, NRS 34.170, this court may consider advisory mandamus when an issue is otherwise likely to elude appeal and "is novel, of great public importance, and likely to recur," Archon Corp. v. Eighth Jud. Dist. Ct., 133 Nev. 816, 820, 822, 407 P.3d 702, 706-07, 708 (2017) (quoting United States u. Horn, 29 F.3d 754, 769 (1st Cir. 1994)). The parties have shown that there is a clear divide in Nevada among discovery commissioners, state court judges, and federal court judges regarding whether NRS 629.620 is constitutional as applied to court-ordered mental and physical examinations conducted during civil discovery.' Further,

"In addition to the instant case where the district court assertedly applied NRCP 35 over NRS 629.620 in regard to medical exam conditions, there are three other cases before this court alone where district court judges and their discovery commissioners have applied NRS 629.260 over

SUPREME COURT OF NEVADA

<O) I947A .F:Mitc> 4 adequate consideration of the issues is unlikely to occur on a subsequent appeal, as discovery will have been completed under the terms of the district court's order. Thus, our intervention is warranted. As we reasoned in Lyft when considering the similar question of whether NRS 52.380 was unconstitutional, determining whether NRS 629.620 supersedes NRCP :35 "is an issue of statewide importance that presents a novel question of law requiring clarification," and this court's "clarification of this issue will assist the district courts and parties alike by resolving uncertainty" over which law governs exams performed during discovery. 137 Nev. at 834, 501 P.3d at 998. Given that the issue presented is "a substantial issue of public policy due to the conflicting interests of plaintiffs and defendants with respect to the procedures" for such exams, id., we elect to entertain the petition under our advisory mandamus framework.2 NRCP 35 and NRS 629.620 irreconcilably conflict NRCP 35 governs court-ordered physical and mental examinations for purposes of litigation and prescribes rules for recording the exam, having observers at the exam, and reporting the exam's findings. NRS 629.620 also covers court-ordered physical and mental examinations, as well as those imposed by contractual or other obligations. The statute sets forth the "rights" of the person being examined, which include having an observer-of-choice and interpreter present and having the exam recorded through audio, stenographic, or video means. NRS 629.620(1)(b), (c), (e). It

NRCP 35 to medical exam conditions. See LV Rest. Mgmt. Corp. v. Eighth Jud. Dist, Ct., Docket No. 89532, Flamingo Paradise Gaming, LLC v. Eighth Jud. Dist. Ct., Docket No. 89783, and Morgan v. Eighth Jud. Dist. Ct., Docket No. 90645.
