Primary Jurisdiction Limits: New York Courts Need Not Refer Common-Law Stray-Voltage Tort Claims to the Public Service Commission

Case: Frasier v Niagara Mohawk Power Corp., 2026 NY Slip Op 01110 (3d Dept Feb. 26, 2026)

1. Introduction

Frasier v Niagara Mohawk Power Corp. arises from a long-running dispute between a dairy farm and its electric utility. Plaintiffs Elmvue Farms, LLC and owner Rick Frasier alleged that “stray voltage” on their Fulton County farm caused herd behavioral changes, reduced milk production, fertility issues, and other health problems. Defendant Niagara Mohawk Power Corporation (d/b/a National Grid) investigated, identified some stray voltage slightly above its internal remediation threshold, and installed a neutral isolator. After years without further complaint, plaintiffs sued in 2019 asserting common-law tort claims—negligence, private nuisance, trespass to land, and trespass to chattels—seeking damages and mandatory injunctive relief compelling abatement.

As the case became trial-ready, defendant moved to stay and refer issues to the Public Service Commission (PSC) under the primary jurisdiction doctrine. Supreme Court granted a stay and directed the PSC to determine whether harmful stray voltage existed, how to mitigate it, and any other issue within its purview. Plaintiffs appealed; the PSC appeared as amicus curiae supporting plaintiffs, urging that referral was unwarranted.

The central issue on appeal was whether adjudicating these tort claims “requires” prior resolution of issues placed within the PSC’s “special competence,” such that the courts should suspend the case and send key questions to the agency.

2. Summary of the Opinion

The Third Department reversed. While recognizing the PSC’s broad supervisory authority over electric utilities and its regulatory role regarding safety, the Court held that primary jurisdiction referral was not warranted here. The Court reasoned that a PSC proceeding would largely address whether the utility was in compliance with generalized minimum regulatory standards, which is not dispositive of common-law due care. The tort claims—duty, breach, causation, and damages, as well as an abatement-oriented injunction—are inherently judicial questions that can be addressed through the adversarial process with expert testimony and, if needed, court-appointed neutrals. The Court also found no meaningful risk of inconsistent adjudications requiring coordination between judicial and administrative branches on these facts.

3. Analysis

3.1 Precedents Cited

A. The primary jurisdiction framework

• Staatsburg Water Co. v Staatsburg Fire Dist., 72 NY2d 147 (1988): Quoted for the core definition of primary jurisdiction—when a claim is court-cognizable but requires resolution of issues committed to an agency’s special competence; courts may suspend proceedings pending agency input. This case supplies the controlling doctrinal test the Third Department applied.
• Capital Tel. Co. v Pattersonville Tel. Co., 56 NY2d 11 (1982): Cited for the policy purpose—coordinating courts and agencies to avoid divergence that could undermine the statutes both must effectuate, and to obtain agency views on technical questions and statutory meaning. The Third Department used this to ask whether referral would genuinely serve coordination and statutory coherence in a tort suit.
• Heller v Coca-Cola Co., 230 AD2d 768 (2d Dept 1996), lv dismissed & denied 89 NY2d 856 (1996): Cited for the “no fixed formula” proposition; application is case-specific, guided by whether the doctrine’s reasons and purposes are served.
• Lauer v New York Tel. Co., 231 AD2d 126 (3d Dept 1997): Reinforces the discretionary, case-by-case nature of applying primary jurisdiction.
• Romine v Laurito, 186 AD3d 913 (3d Dept 2020), appeal dismissed 36 NY3d 939 (2020), appeal dismissed & lv denied 36 NY3d 1088 (2021): Re-cited with Staatsburg to confirm how the doctrine operates procedurally (suspension pending referral) and substantively (special competence inquiry).
• Calle v National Grid USA Serv. Co., Inc., 230 AD3d 556 (2d Dept 2024): Cited both in the general statement of doctrine and later in a comparative string cite. The Third Department distinguished the present tort claims from contexts where referral better serves regulatory coordination.

B. The PSC’s statutory authority—and its limits in a tort case

• Matter of National Energy Marketers Assn. v New York State Pub. Serv. Commn., 33 NY3d 336 (2019): Cited to show the PSC’s “broad regulatory authority” over utility service and safety; it frames the agency’s legitimate domain.
• Matter of Cahill v Public Serv. Commn., 69 NY2d 265 (1986), certs denied 484 US 829, 830 (1987): Cited similarly to confirm the PSC’s authority and expertise in utility regulation and safety oversight.
• Proceeding on Motion of the Commission to Examine the Safety of Electric Transmission and Distribution Systems, NY PSC Case No. 04-M-0159 (Mar. 22, 2013): Cited as evidence that the PSC has exercised supervisory authority on stray voltage through testing/mitigation/reporting requirements and by adopting the National Electric Safety Code for electric facilities.

These authorities established that the PSC is powerful in the regulatory sphere. But the Third Department treated that point as necessary—not sufficient—for primary jurisdiction. The operative question remained whether the adjudication of the tort claims first required PSC determinations within exclusive or special competence.

C. Regulatory compliance does not resolve common-law due care

• Miner v Long Is. Light. Co., 40 NY2d 372 (1976): Cited for the principle that compliance with regulatory standards is not dispositive of due care. The Court used this to show why a PSC compliance inquiry would not answer negligence and related tort duties.
• Holtz v Niagara Mohawk Power Corp., 147 AD2d 857 (3d Dept 1989): Reinforces that regulatory standards often function as a baseline (“floor”), not the ceiling of tort responsibility.

D. Courts’ familiarity with utility/stray voltage litigation

• Smith v Consolidated Edison Co. of N.Y., Inc., 104 AD3d 428 (1st Dept 2013)
• Flex-O- Vit USA v Niagara Mohawk Power Corp., 292 AD2d 764 (4th Dept 2002), lv dismissed 99 NY2d 532 (2002)
• Lane v New York State Elec. & Gas, 99 AD2d 597 (3d Dept 1984)

These citations supported the Third Department’s pragmatic point: technical complexity does not itself trigger primary jurisdiction; courts routinely manage utility-related tort disputes using experts and established negligence frameworks (the Court also referenced PJI 2:195, 2:200, 2:206).

E. Distinguishing cases where primary jurisdiction may be appropriate

• Riverdale Jewish Ctr. v Brooklyn Union Gas Co., 237 AD3d 414 (1st Dept 2025)
• Calle v National Grid USA Serv. Co., Inc., 230 AD3d 556 (2d Dept 2024)
• Romine v Laurito, 186 AD3d 913 (3d Dept 2020)
• Township of Thompson v New York State Elec. & Gas Corp., 25 AD3d 850 (3d Dept 2006), lv denied 6 NY3d 713 (2006)
• Brownsville Baptist Church v Consolidated Edison Co. of N.Y., 272 AD2d 358 (2d Dept 2000)
• Guglielmo v Long Is. Light. Co., 83 AD2d 481 (2d Dept 1981)

By “compare” citation, the Court signaled that those decisions involved circumstances more tightly bound to regulatory administration, tariff/policy, or coordination concerns. Here, by contrast, the claims did not “arise from” PSC rules or policy; they were traditional tort claims requiring ordinary judicial findings.

F. Tools for handling technical complexity without agency referral

• Matter of Harkenrider v Hochul, 38 NY3d 494 (2022): Cited for courts’ authority to deploy procedural tools (including neutrals) in complex matters.
• Kesseler v Kesseler, 10 NY2d 445 (1962)
• Kaplowitz v Borden, Inc., 189 AD2d 90 (1st Dept 1993)
• Zirinsky v Zirinsky, 138 AD2d 43 (1st Dept 1988)

Grounded in CPLR 4001 and 4212, these citations supported the Court’s alternative: rather than staying a tort case for agency input, trial courts can use referees and court-appointed neutral experts to assist with highly technical disputes.

G. Injunctive abatement and separation-of-functions concerns

• Siewert v Northern States Power Co., 793 NW2d 272 (Minn 2011): Cited to show that courts can craft injunctions that order “abatement” without micromanaging utility engineering choices—reducing concern about interference with regulatory domains.

3.2 Legal Reasoning

The Court’s reasoning proceeded in three main steps:

1. Identify the agency’s sphere—then ask what the referral would actually decide. The Court acknowledged the PSC’s broad authority under Public Service Law §§ 65 and 66, including the ability to investigate utility methods and prescribe reasonable improvements to protect the public. It also recognized that the PSC has imposed stray-voltage-related requirements and adopted the National Electric Safety Code. But the Court concluded that a PSC referral here would largely yield a determination of present compliance with administrative standards—standards that function as a generalized minimum and do not resolve the tort duty of care.
2. Regulatory compliance is not the tort standard. Relying on Miner v Long Is. Light. Co. and Holtz v Niagara Mohawk Power Corp., the Court stressed that regulatory standards are not dispositive as to due care. Plaintiffs’ experts asserted that dairy-farm stray-voltage duty may exceed the regulatory “floor,” and the PSC itself acknowledged it lacks expertise on cattle impacts and would need outside experts to opine on whether voltage is “harmful” in that sense. This undermined the premise that the PSC’s “special competence” was necessary to decide the case’s core questions.
3. Complexity does not divest courts of their role; courts have tools to manage it. The Court rejected the notion that technical disputes over identifying stray voltage justify stopping the judicial process. It noted New York courts’ familiarity with utility disputes and stray-voltage cases, and emphasized that expert testimony ordinarily supplies the needed technical foundation. Where experts sharply diverge, courts can appoint neutrals or referees (CPLR 4001, 4212) rather than transferring responsibility to an agency.

Finally, the Court found no practical “coordination” concern. Even as to injunctions, it reasoned that Supreme Court could order abatement if harmful stray voltage is proven, without dictating the precise engineering solution—reducing any perceived risk of conflicting commands between court and regulator.

3.3 Impact

• Narrowing primary jurisdiction in utility-related tort suits: The decision strengthens the proposition that when plaintiffs plead traditional tort causes of action (negligence, nuisance, trespass) not grounded in PSC regulations, courts need not refer technical questions to the PSC merely because the defendant is a regulated utility.
• Regulatory “floor” vs. tort “ceiling”: By emphasizing that PSC standards are minimum, generalized requirements, the opinion encourages litigants and courts to treat compliance evidence as relevant but not determinative of negligence and related claims—particularly in specialized contexts (here, dairy-cattle physiology and farm environments).
• Litigation management roadmap: Trial courts faced with competing engineers, electricians, veterinarians, and epidemiological/production evidence can look to CPLR-based tools—referees and neutral experts— rather than staying actions for agency processes that may not squarely address causation or harms.
• Injunctive relief framed as “abatement”: The Court’s acceptance that a court may order abatement without prescribing the means may influence how future plaintiffs draft injunction requests and how defendants argue regulatory interference.

4. Complex Concepts Simplified

• Primary jurisdiction doctrine: A court-made rule that sometimes pauses a lawsuit so an administrative agency can answer issues within its specialized expertise. It applies only when the lawsuit’s enforcement truly depends on resolving agency-committed questions first.
• Regulatory standards as a “floor”: Agency rules often set minimum safety requirements. A defendant can comply with those rules and still be negligent if reasonable care under the circumstances required more.
• Stray voltage (neutral-to-earth voltage): In grounded-neutral electrical systems, some return current can flow through the earth. If there is a voltage difference between the utility’s neutral conductor and the earth, current can move between them. On farms, cows may become part of that path when they contact bonded metal equipment and the ground, potentially affecting behavior and production.
• Abatement injunction: An equitable order requiring a harmful condition to be eliminated. Courts can order the result (stop the harmful stray voltage) without dictating the precise technical method (which preserves flexibility and reduces overlap with regulatory engineering choices).
• Court-appointed neutral expert / referee (CPLR 4001, 4212): Procedural mechanisms allowing courts to obtain independent technical assistance to understand disputed scientific/engineering matters.

5. Conclusion

Frasier v Niagara Mohawk Power Corp. clarifies that New York’s primary jurisdiction doctrine does not automatically divert technically complex, utility-adjacent disputes to the PSC when plaintiffs pursue common-law tort remedies. The Third Department’s key contributions are (1) separating regulatory compliance from common-law due care, (2) insisting that complexity is manageable within the judicial process through experts and neutral-aid tools, and (3) confirming that abatement-focused equitable relief can be crafted without entangling courts in the PSC’s regulatory functions. The result is a stronger pathway for litigants to try stray-voltage tort claims in court without mandatory agency detours.
