Independent-Contractor Rule Limits FTCA Premises-Liability Claims in New Mexico Absent U.S. Control of the Worksite or Instrumentality

1. Introduction

In Dean v. United States (10th Cir. Mar. 17, 2025), Larry Dean, a VERUS Research (VERUS) employee, suffered a serious leg injury while working inside an Air Force-owned anechoic chamber at Kirtland Air Force Base. VERUS used the chamber to perform testing under a contract connected to the Air Force Research Laboratory (AFRL).

After the Air Force denied his administrative claim, Dean sued the United States under the Federal Tort Claims Act (FTCA), alleging negligence based on premises-safety theories: failure to keep the premises safe, failure to reasonably inspect, and failure to warn about an unstable floor block. The central appellate issue was whether, under New Mexico law (applied via the FTCA), the United States owed a duty of care to an independent contractor’s employee for injuries arising from conditions in the work area.

2. Summary of the Opinion

The Tenth Circuit affirmed summary judgment for the United States. It held that New Mexico’s “independent contractor rule”—as previously described by the Tenth Circuit—limits a hirer/landowner’s duty to an independent contractor’s employee, subject to two exceptions: (1) when the hirer controls the premises on which the work is performed, or (2) when the hirer retains control over the contractor’s performance of the work.

Dean conceded (or did not meaningfully dispute) that the government did not control VERUS’s manner of work. On the remaining exception—control of the premises—the court found no genuine dispute of material fact: the record showed that during testing VERUS controlled the placement, movement, and layout of the foam blocks that served as the walkway and allegedly created the hazard. Contract language referencing “Government-controlled working space” did not overcome the undisputed operational facts.

3.1. Precedents Cited

  • Mengert v. United States, 120 F.4th 696 (10th Cir. 2024): supplied the de novo standard for summary judgment review and reiterated the movant’s Rule 56 burden.
  • Cillo v. City of Greenwood Vill., 739 F.3d 451 (10th Cir. 2013): reinforced that evidence is viewed in the non-movant’s favor with reasonable inferences drawn accordingly.
  • Strawberry Water Users Ass'n v. United States, 109 F.4th 1287 (10th Cir. 2024) and Stokes v. United States, 967 F.3d 1034 (10th Cir. 2020): framed the FTCA as a limited sovereign-immunity waiver and emphasized that courts apply the relevant state’s tort law as though the United States were a private person “under like circumstances.”
  • Nelson v. United States, 915 F.3d 1243 (10th Cir. 2019) and Daigle v. Shell Oil Co., 972 F.2d 1527 (10th Cir. 1992): governed how federal courts identify and predict state law (highest court first; intermediate decisions as indicators absent contrary high-court signals).
  • Ohlsen v. United States, 998 F.3d 1143 (10th Cir. 2021): restated the FTCA’s independent-contractor limitation—“the United States can't be liable under the FTCA for the negligence of its independent contractors”—thus forcing Dean’s claim into a “direct negligence/duty” inquiry.
  • Ford v. Bd. of Cnty. Comm'rs, 879 P.2d 766 (N.M. 1994) and Rodriguez v. Del Sol Shopping Ctr. Assocs., 326 P.3d 465 (N.M. 2014): represented New Mexico’s broad premises-liability duty to lawful entrants and, post-Rodriguez, its Restatement (Third) duty framework that separates foreseeability from duty-limiting “policy” analysis.
  • Adams v. C3 Pipeline Construction Inc., 30 F.4th 943 (10th Cir. 2021): was pivotal. The panel treated Adams as binding Tenth Circuit interpretation that New Mexico premises-liability doctrine includes the independent contractor rule and its two exceptions.
  • Patterson v. PowderMonarch, LLC, 926 F.3d 633 (10th Cir. 2019): supplied the intra-circuit state-law rule: a panel’s interpretation of state law binds later panels unless the state’s highest court intervenes.
  • Valdez v. Cillessen & Son, Inc., 734 P.2d 1258 (N.M. 1987) and Sherman v. Cimarex Energy Co., 318 P.3d 729 (N.M. Ct. App. 2013): supported the independent contractor rule as part of New Mexico’s approach to hirer liability.
  • Lopez v. Devon Energy Production Co., 468 P.3d 887 (N.M. App. 2020): advanced an analysis suggesting premises liability should not be treated as an “exception to a no-liability rule,” emphasizing direct duty under Restatement (Third) §§ 7(a) and 51, but it also acknowledged the duty might be “modified or limited” given independent-contractor status. The Tenth Circuit declined to treat Lopez as displacing Adams.
  • Requarth v. Brophy, 801 P.2d 121 (N.M. 1990): defined the kind of “control” that triggers hirer/landowner duty to a contractor’s employee: “some specific control over the premises during the performance of the work, or over the instrumentality that proximately caused the employee's injury,” and that general control is usually insufficient when the hazard is created by the contractor and unknown to the owner.
  • Helget v. City of Hays, 844 F.3d 1216 (10th Cir. 2017): supplied the summary-judgment principle that a party cannot merely speculate that a factfinder may disbelieve a witness; the party must produce affirmative evidence creating a genuine dispute.

3.2. Legal Reasoning

  1. FTCA framework forces a “state-law duty” inquiry. Because VERUS was an independent contractor, 28 U.S.C. § 2671 (as applied in Ohlsen) precluded vicarious liability for VERUS’s negligence. Dean therefore had to show the United States breached a duty it owed directly to him under New Mexico law.
  2. The panel treated “Adams” as controlling on New Mexico premises liability involving contractor employees. Dean argued that New Mexico premises liability imposes a uniform duty of ordinary care to all lawful entrants (per Ford and Rodriguez). The government countered with Adams, which explicitly described New Mexico premises liability as incorporating the independent contractor rule. Invoking Patterson, the panel concluded it was bound by Adams absent an intervening decision of the New Mexico Supreme Court.
  3. “Lopez” did not displace “Adams” and did not persuade the panel to predict a contrary New Mexico Supreme Court outcome. The panel gave several reasons: (i) Lopez predates Adams, so it cannot be the “intervening” authority contemplated by Patterson; (ii) it is an intermediate appellate decision; (iii) its remand-oriented discussion was precatory; and (iv) it was factually distinguishable—Dean’s injury was tied to the instability of foam blocks that the record showed were under VERUS’s control. The court also emphasized that even under Rodriguez’s Restatement (Third) framework, duty may be limited by “articulated countervailing principle or policy,” and the independent contractor rule could qualify as such a policy-based limitation.
  4. Applying the rule, neither exception created a triable duty. Dean did not meaningfully contest the “control over performance” exception. As to “control of the premises,” the court applied Requarth: the United States needed “specific control” during performance or over the injury-causing instrumentality. The government produced evidence that VERUS controlled the placement and movement of the blocks during testing and that others were not permitted to enter or interfere. Dean failed to controvert these facts with evidence.
  5. Contract language did not create a genuine dispute. Dean relied on a contract phrase referencing “Government-controlled working space,” arguing ambiguity requiring extrinsic evidence. The panel held that, even assuming ambiguity, the extrinsic evidence in the summary-judgment record showed VERUS actually controlled the chamber layout and the blocks during the relevant work, so the “control” exception still was not met.
  6. Credibility attacks cannot substitute for evidence. The panel rejected Dean’s “contradictory testimony” argument under Helget: speculation that a jury might disbelieve the government’s witness does not create a genuine issue of material fact without affirmative contrary evidence.

3.3. Impact

Although designated as an “Order and Judgment” and “not binding precedent” except under limited doctrines, the decision is likely to be cited for its persuasive value in FTCA litigation arising in New Mexico, particularly in workplace-injury cases involving federal facilities used by contractors.

Key practical effects include:

  • Reinforcing a duty “gatekeeping” function in contractor-employee premises cases. Plaintiffs will face an early, duty-based hurdle (often resolvable at summary judgment) unless they can show the United States exercised the kind of “specific control” identified in Requarth.
  • Elevating “operational control” evidence over “paper control” language. Contract labels (e.g., “Government-controlled working space”) may matter less than day-to-day control of the alleged hazard or instrumentality.
  • Stabilizing Tenth Circuit doctrine around “Adams” absent clear New Mexico Supreme Court intervention. The panel signaled reluctance to read intermediate authority (like Lopez) as an implicit repudiation of the independent contractor rule, especially where the New Mexico Supreme Court has not squarely addressed whether that rule is a Restatement (Third) “policy” limitation post-Rodriguez.
  • Narrowing the path for FTCA premises-liability recovery by contractor employees. Unless plaintiffs can connect the injury to a condition controlled by federal personnel (or to retained control over the work), the FTCA claim may fail on duty, even where the United States owns the facility and broadly controls access.

4. Complex Concepts Simplified

FTCA (Federal Tort Claims Act)
A statute that allows certain negligence suits against the United States, but only to the extent a private person would be liable under the relevant state’s law.
Sovereign immunity
The baseline rule that the government cannot be sued unless it consents; the FTCA is a limited consent.
Independent contractor exception (FTCA)
The United States is generally not liable for the negligence of independent contractors; plaintiffs must show negligence by federal employees or a direct duty breached by the United States.
Premises liability
Liability based on conditions on land or in a building (e.g., hazards on a walkway) and the duty of the owner/occupier to maintain reasonably safe premises.
Independent contractor rule (state tort law concept)
A doctrine limiting when a hirer/owner is liable for injuries to a contractor’s employees; commonly turns on whether the hirer controlled the premises or the work.
“Control” (as used here)
Not mere ownership or general oversight, but “specific control” over the premises during the work or over the instrumentality that caused the injury (per Requarth v. Brophy).
Summary judgment
A pretrial decision for one side when no genuine dispute of material fact exists and the movant is entitled to judgment as a matter of law (Fed. R. Civ. P. 56).

5. Conclusion

Dean v. United States affirms that, in the Tenth Circuit’s view, New Mexico’s independent contractor rule remains a meaningful limitation on premises-liability claims brought by independent contractors’ employees—even in the post-Rodriguez Restatement (Third) duty framework—unless a plaintiff can show that the hirer/landowner exercised the requisite specific control over the worksite during performance or over the injury-causing instrumentality.

The decision’s core takeaway is evidentiary as much as doctrinal: contractor-employee plaintiffs must develop concrete facts demonstrating federal “control” at the operational level, not merely rely on ownership, access restrictions, or ambiguous contract phrasing, to survive summary judgment on duty under the FTCA.
