NRS 533.450(1) Standing Requires an Existing Personal or Property Right—Speculative Interests from Pending Water Applications Are Insufficient

Case: GOLD STANDARD VENTURES (US) INC. v. THORSON, P.E., 142 Nev., Advance Opinion 10 (Nev. Feb. 12, 2026)
Court: Supreme Court of Nevada (en banc)
Posture: Appeal from dismissal of petition for judicial review of a Nevada State Engineer decision

1. Introduction

This decision addresses who may obtain judicial review of Nevada State Engineer actions under NRS 533.450(1) when the challenged decision concerns the administration of water rights in a basin but the challenger holds no existing water right. The appellant, Gold Standard Ventures (US) Inc., a subsidiary of Orla Mining Ltd. (collectively “Orla”), sought water rights in the Dixie Creek–Tenmile Creek basin for a proposed mining operation. Orla believed a 2023 State Engineer letter approving the Nevada Division of State Lands’ (NDSL) withdrawal of a proof of beneficial use filing and “conditional relinquishment” of groundwater rights reduced water available for future appropriation and thus diminished the likelihood Orla’s pending applications would be granted.

The district court dismissed Orla’s petition for judicial review, holding Orla (1) lacked standing as a non-aggrieved party under NRS 533.450(1) and (2) filed untimely. On appeal, Orla challenged the standing and timeliness rulings and argued for equitable relief and due process based on lack of notice despite a “request for correspondence.”

The Supreme Court affirmed solely on standing, holding that Orla’s asserted harms were speculative and not tied to any existing personal or property right.

2. Summary of the Opinion

The court construed NRS 533.450(1) to require that—where the State Engineer decision is not made pursuant to the specific statutes enumerated in the statute (e.g., NRS 533.270 to 533.445, NRS 533.481, 534.193, 535.200, or 536.200)—a petitioner must show the decision adversely affects the petitioner’s own existing personal or property right. Because Orla held no existing water rights impacted by the challenged decision, Orla was not “aggrieved” and could not “unilaterally insert itself into proceedings” involving NDSL’s rights.

Having found no standing, the court declined to reach timeliness, equitable tolling, or due process notice issues, adding that notice was not required where no existing rights were affected. The court also emphasized public policy reflected in 2025 legislation establishing a voluntary water-rights retirement program, reasoning that broad standing would undermine voluntary relinquishment by enabling challenges by anyone with only speculative interests.

3. Analysis

3.1. Precedents Cited

  • Citizens for Cold Springs v. City of Reno, 125 Nev. 625, 218 P.3d 847 (2009).
    Cited for de novo review on “upon whom a statute conferred standing.” The majority uses it primarily as a standard-of-review anchor for statutory standing interpretation, not as a substantive expansion of standing in this water context.
  • Wilson v. Pahrurnp Fair Water, LLC, 137 Nev. 10, 481 P.3d 853 (2021).
    Cited for de novo review of statutory interpretation and later for the proposition that notice is not required where a decision does not limit established water rights. The majority uses Wilson to support rejecting Orla’s due process arguments because Orla had no established rights.
  • Great Basin Water Network v. Taylor, 126 Nev. 187, 234 P.3d 912 (2010).
    The majority relies on Great Basin for methodology: a statute is ambiguous if susceptible to more than one reasonable interpretation; if ambiguous, the court consults reason, public policy, and context. This case is central to the interpretive move that enables the court to narrow standing beyond Orla’s reading.
  • Leven v. Frey, 123 Nev. 399, 168 P.3d 712 (2007), quoting McKay v. Bd. of Supervisors, 102 Nev. 644, 730 P.2d 438 (1986).
    Used to justify examining “context and the spirit of the law” once ambiguity is found. This undergirds the court’s turn to public policy—especially the 2025 retirement program legislation.
  • Marvin v. Fitch, 126 Nev. 168, 232 P.3d 425 (2010).
    Cited for the pleading standard on a motion to dismiss: accept factual allegations as true. The court assumes Orla’s claim that the decision will adversely affect its applications, yet still finds standing lacking because the interest is not a legally cognizable existing right.
  • NRS 233B.110 and NAIVIC v. State, Dep't of Bus. & Indus., Div. of Ins., 139 Nev. 18, 524 P.3d 470 (2023).
    These are invoked to illustrate broader “statutory standing principles”: judicial review is typically tied to legal rights/privileges the Legislature created and provided a vehicle to vindicate. The majority uses these authorities to reinforce a rights-linked model of standing.
  • Valley Bank of Nev. v. Ginsburg, 110 Nev. 440, 827 P.2d 729 (1994), quoting In re Est. of Hughes v. First Nat'l Bank of Neu., 96 Nev. 178, 605 P.2d 1149 (1980).
    Used to define “aggrieved” in the appellate-standing sense: a party is aggrieved when a personal or property right is “adversely and substantially affected.” The majority treats NRS 533.450(1)’s “in the nature of an appeal” phrase as importing this concept.
  • Eikelberger v. Nev. State Bd. of Acct., 91 Nev. 98, 531 P.2d 853 (1975), and United States v. State Eng'r, 117 Nev. 585, 27 P.3d 51 (2001).
    Cited for the administrative-law proposition that review is limited to those whose rights/privileges/duties are affected and that the State Engineer is an administrative agency. The majority uses these to situate NRS 533.450(1) within general administrative review norms—even while acknowledging the State Engineer’s unique statutory scheme.
  • Howell v. Ricci, 124 Nev. 1222, 197 P.3d 1044 (2008).
    Quoted for the phrase that a person may challenge a State Engineer decision “so long as the decision affects the person’s interests concerning the rights.” The majority reads “concerning the rights” as requiring linkage to the challenger’s own rights.
  • Sierra Pacific Industries v. Wilson, 135 Nov. 105, 440 P.3d 37 (2019).
    Addressed primarily in response to the dissent. The majority distinguishes Sierra as not having decided standing and as being focused on anti-speculation/extension-of-time issues, thus providing “no support” for broader standing in this case.
  • Perry v. Sindermann, 408 U.S. 593 (1972).
    Cited (in a notice/due process footnote) for the principle that a mere “subjective expectancy” is not protected by procedural due process, reinforcing the majority’s view that Orla’s asserted interest is an unprotected expectancy.
  • Dissent-only citations: Stockrneier v. Nev. Dep't of Corr., 122 Nev. 385, 135 P.3d 220 (2006) (partially disavowed by Buzz Stew, LLC v. City of North Las Vegas, 124 Nev. 224, 181 P.3d 670 (2008)); In re Nev. State Eng'''. Ruling No. 5823, 128 Nev. 232, 277 P.3d 449 (2012); Benson v. State Eng'r, 131 Nev. 772, 358 P.3d 221 (2015); Desert Valley Water Co. v. State, 104 Nev. 718, 766 P.2d 886 (1988); Food & Drug Administration v. R. J. Reynolds Vapor Co., 606 U.S. 226 (2025); Nuclear Regul. Cornm'n v. Texas, 605 U.S. 665 (2025); Heller v. Leg. of State of Nev., 120 Nev. 456, 93 P.3d 746 (2004); Doe v. Bryan, 102 Nev. 523, 728 P.2d 443 (1986); In re Water Rights in the Humboldt River Stream Sys., 49 Nev. 357, 246 P. 692 (1926).
    These authorities frame the dissent’s textualist theory: “any person” + “interests” signals a broader grant of review, not limited to holders of existing rights or to parties below; federal analogies (especially R. J. Reynolds Vapor Co.) are used to argue that “any person adversely affected” is intentionally inclusive.

3.2. Legal Reasoning

(a) Identifying ambiguity and choosing an interpretive frame.
The majority accepts that NRS 533.450(1) can reasonably be read in two ways: Orla’s broad reading (anyone whose interests are affected by a decision relating to administration of determined rights) versus the State Engineer’s narrower reading (the decision must affect the petitioner’s interests tied to the petitioner’s own determined rights). Finding the text ambiguous, the court adopts a contextual and policy-driven construction.

(b) “Aggrieved” and “in the nature of an appeal” as narrowing language.
The phrase “in the nature of an appeal” becomes pivotal. The court analogizes NRS 533.450(1) review to appellate standing doctrine (via Valley Bank of Nev. v. Ginsburg), importing the “personal right or right of property” requirement into NRS 533.450(1)’s “feeling aggrieved” language.

(c) Distinguishing protectable legal interests from speculative expectancies.
Even accepting Orla’s allegation that the decision reduces water available for future appropriation, the court characterizes the asserted injury as “layers of speculation” because it depends on multiple contingencies: Orla obtaining approvals, acquiring water, and translating that into a protectable entitlement. The court ties this to due process doctrine (Perry v. Sindermann) and to administrative review principles (Eikelberger v. Nev. State Bd. of Acct.).

(d) Rejecting “unilateral insertion” into another rights-holder’s proceeding.
The court’s most forceful doctrinal move is to treat Orla as a stranger to NDSL’s rights administration and to require a pre-existing, legally cognizable right in Orla that the decision affected. The court clarifies it is not adopting a categorical “must-have-been-a-party-below” rule; a nonparty could have standing if its own existing rights are affected.

(e) Public policy and 2025 voluntary retirement legislation as confirmatory context.
After concluding Orla’s reading would confer overly broad standing (potentially allowing any pending applicant to challenge senior-rights decisions), the court reinforces its interpretation by referencing the 2025 Nevada Voluntary Water Rights Retirement Program (A.B. 104 and S.B. 36). The court reasons that allowing challenges by those with merely speculative interests would “interfere” with voluntary relinquishment and participation in the program, which is designed to retire rights “in perpetuity” and make them unavailable for appropriation.

Doctrinal takeaway: The decision effectively creates a two-step gate for NRS 533.450(1) review in the “administration of determined rights” category: (1) the petitioner must show a concrete adverse effect; and (2) that adverse effect must be to a personal or property right the petitioner already possesses (not a hoped-for right via future appropriation).

3.3. Impact

  • Narrowing of who can sue in basin-wide water administration disputes.
    Parties with only pending applications or commercial development plans (mining, agriculture expansion, municipal growth) will have a harder time establishing standing to challenge State Engineer actions affecting the “available” water pool unless they can tie the decision to an existing water right or other protectable property interest.
  • Stability for voluntary relinquishment/retirement transactions.
    By insulating voluntary relinquishment decisions from challenge by prospective appropriators, the opinion promotes transactional certainty for rights holders and supports the functional goals of the 2025 retirement program framework.
  • Less judicial review of informal or bilateral State Engineer resolutions.
    The case arose from a letter-based decision not copied to Orla despite a “request for correspondence.” Because the court resolves the case on standing, agencies and rights holders may face fewer third-party challenges to informal resolutions—at the possible cost of reduced external oversight.
  • Future litigation likely shifts to defining “existing personal or property right.”
    The decision leaves room for disputes over what qualifies: e.g., existing certificated rights in the basin; contractual interests (leases/options); vested permit interests; or rights affected through interference, priority administration, or curtailment.
  • Potential legislative response.
    The dissent’s textual argument (that “any person” and “interests” reflect deliberate breadth) tees up the possibility that the Legislature could clarify NRS 533.450(1) if it prefers broader review access, especially for parties affected competitively by allocation decisions.

4. Complex Concepts Simplified

  • Standing / “aggrieved person”: A legal requirement that determines who is allowed to bring a case. Here, the majority requires the challenger to show the decision harmed an existing personal or property right—not merely a business plan or hope to obtain water later.
  • NRS 533.450(1) judicial review “in the nature of an appeal”: The statute treats review somewhat like an appeal, and the court uses that phrase to import appellate-style limits (only those whose rights are substantially affected can seek review).
  • Determined rights: A term used in Nevada water law referring to rights that have been formally adjudicated/determined (often through decree processes). The court focuses on decisions “relat[ing] to the administration of determined rights.”
  • Proof of beneficial use (PBU): A demonstration that water was actually put to an approved beneficial use (a foundational concept in western water law). Here, NDSL filed a PBU tied to evaporation offsets; later it sought to withdraw it and conditionally relinquish certain rights.
  • Relinquishment/retirement of water rights: A voluntary giving up of rights so the water is no longer available for appropriation. The court emphasizes 2025 legislation making retired rights unavailable “in perpetuity,” using it to support limiting who can challenge such actions.
  • Procedural due process notice: The right to notice and an opportunity to be heard when the government affects protected rights. The court held Orla had no protected right at stake—only an expectancy—so individualized notice was not required.

5. Conclusion

GOLD STANDARD VENTURES (US) INC. v. THORSON, P.E. establishes a consequential limit on who may seek judicial review under NRS 533.450(1) when challenging State Engineer decisions relating to administration of determined water rights: absent the statute’s enumerated decision-types, the petitioner must show that the challenged action adversely affects the petitioner’s existing personal or property right, not merely a speculative interest rooted in pending applications or hoped-for future appropriations. The court’s approach aligns standing with appellate “aggrieved party” doctrine and reinforces legislative policy favoring voluntary water-right retirement and relinquishment without exposure to challenges by prospective appropriators.

The dissent underscores that the statutory text (“any person,” “interests”) could support broader access to judicial review, suggesting this decision may become a focal point for future litigation—or legislative clarification—over the balance between administrative finality, water-rights market/retirement stability, and open-court oversight of basin-level allocation consequences.
