OPINION AND ORDER Before the Court is Third-Party Defendant KAMO Electric Cooperative, Inc.’s Motion to Dismiss Defendant Grand River Dam Authority’s Third-Party Claim for Constructive Indemnification. (Docket No. 78). After considering the parties’ briefing on the matter and the applicable caselaw, Third-Party Defendant KAMO Electric Cooperative, Inc.’s Motion to Dismiss is hereby GRANTED. Background and Procedural History On May 27, 2025, Plaintiffs Theresa Marie Sanders, Adrian Kemohah Sanders, Mahada Bernadette Sanders, James P. Boese, Monica Boese, and Alysha Boese (“Plaintiffs”) filed their First Amended Complaint against Defendant Grand River Dam Authority (“GRDA”).1 (Docket No. 65). Plaintiffs, members of the Osage Nation, bring several claims for relief, including quiet

1 The original Complaint was filed on June 4, 2024. (Docket No. 1). title, trespass, unjust enrichment, fraud, slander of title, injury to real property, and nuisance. Id. at 5-11. Plaintiffs also seek punitive damages. Id. at 11-12. According to the Amended Complaint, “Plaintiffs collectively own an undivided ¾ interest in restricted title in and to the Southeast Quarter (SE/4) of Section 16, Township 21 North, Range

9 East of the Indian Base and Meridian, Osage County, State of Oklahoma[.]” Id. at 2. GRDA owns and maintains multiple, multi-pole electric transmission lines, which traverse a half-mile portion of the southern edge of said property. 2 Id. at 2-3. Plaintiffs allege that neither GRDA nor its predecessors obtained an electric line easement from Plaintiffs or their predecessors in title. Id. at 4. They further allege that no record exists establishing that KAMO Electric Cooperative, Inc. (“KAMO”) was granted a right of way over the property, rendering KAMO’s assignment of the right-of-way easement to GRDA on July 15, 1998, unlawful and invalid. Id. at 3-6, 8-9. Generally, Plaintiffs assert that GRDA and/or their predecessors, including KAMO, have “unlawfully and willfully maintained the Electric Lines that are now owned and operated by GRDA, since the dates of their respective construction.” Id. at 4-5.

On June 10, 2025, GRDA filed its Third-Party Complaint against KAMO, asserting a claim for implied indemnity. (Docket No. 70). GRDA alleges that to the extent it is found liable, it is entitled to indemnity as “KAMO contracted with Plaintiffs’ predecessor in interest of the right-of- way, constructed the complained of electrical line(s), and then assigned that right-of-way and electrical line(s) to GRDA.” Id. at 6-7. According to GRDA, KAMO’s activities establish a special relationship between KAMO, the parties, and these events. Id. GRDA maintains that

2 Plaintiffs allege that these multiple, multi-pole electric lines were constructed at “an unknown point in time.” (Docket No. 65 at 3). However, the first electric line was placed on the property in 1942. Id. at 6-7. Plaintiffs confirmed that they are seeking damages from GRDA “in part” for KAMO’s actions, and GRDA demands indemnity from KAMO for Plaintiff’s damages for the time period prior to GRDA’s acquisition of the right-of-way and electrical line. Id. at 5, 7. KAMO filed its Motion to Dismiss Defendant GRDA’s Third-Party Complaint on July 1,

2025. (Docket No. 78). GRDA filed its Response on July 17, 2025 (Docket No. 92), and KAMO filed its Reply on July 23, 2025. (Docket No. 100). As such, GRDA’s motion is ripe for review.3 Legal Standard KAMO seeks dismissal of GRDA’s indemnity claim for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6) and 14(a)(2)(A). See 5B Wright & Miller, Fed. Prac. & Proc.: Civil 3d § 1356 (“The motion under [Rule 12](b)(6) is available to test a claim for relief in any pleading, whether it be in the plaintiff’s original complaint, a defendant’s counterclaim, a defendant’s crossclaim or counterclaim thereto, or a third-party claim or any other Federal Rule of Civil Procedure 14 claim.”). In Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007) and Ashcroft v. Iqbal, 556 U.S. 662 (2009), the United States Supreme Court set forth the plausibility standard

applicable to a motion to dismiss filed under Rule 12(b)(6). Bell Atlantic stands for the summarized proposition that “[t]o survive a motion to dismiss, a complaint must contain sufficient factual matter, accepted as true, to ‘state a claim for relief that is plausible on its face.’” Ashcroft, 556 U.S. at 678, quoting Bell Atl., 550 U.S. at 570. “A claim has facial plausibility when the plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Id., citing Bell Atl., 550 U.S. at 556; see also

3 On July 17, 2025, Plaintiffs filed a Third-Party Complaint against KAMO. (Docket No. 95). On August 5, 2025, KAMO filed its Motion to Dismiss Plaintiffs’ Complaint/Third-Party Complaint Filed Against KAMO. (Docket No. 105). The Court addresses this motion by separate Opinion and Order. Robbins v. Oklahoma, 519 F.3d 1242, 1247 (10th Cir. 2008) (interpreting the plausibility standard as referring “to the scope of the allegations in the complaint: if they are so general that they encompass a wide swath of conduct, much of it innocent, then the plaintiffs have not nudged their claims across the line from conceivable to plausible.”) (quotation omitted). However, a court need

not accept as true allegations that are conclusory in nature. Ashcroft, 556 U.S. at 678 (“[T]he tenet that a court must accept as true all the allegations contained in a complaint is inapplicable to legal conclusions. Threadbare recitals of the elements of a cause of action, supported by mere conclusory statements, do not suffice.”), citing Bell Atl., 550 U.S. at 555. Discussion KAMO seeks dismissal of GRDA’s third-party claim for constructive indemnification under Fed. R. Civ. P. 12(b)(6), claiming GRDA has not sufficiently alleged or established primary or secondary liability under Oklahoma law to support its claim. (Docket No. 78 at 3-4, 10-12, 15). Specifically, KAMO argues GRDA’s pleading fails to identify a statutory or common law basis for GRDA’s liability as it relates to KAMO’s “pre-1998 conduct.” Id. at 3-4, 6, 10-12; Docket No.
