Opinion

UNITED STATES DISTRICT COURT DISTRICT OF SOUTH DAKOTA CENTRAL DIVISION

METROPOLITAN LIFE INSURANCE 3:24-CV-03029-RAL COMPANY, TRINET HR XI, INC., Plaintiffs, OPINION AND ORDER GRANTING MOTION FOR PRELIMINARY vs. INJUNCTION DURIN MUNDAHL, INDIVIDUALLY AND AS THE PERSONAL REPRESENTATIVE OF THE ESTATE OF JOYE M. BRAUN; AND MORGAN BRINGS PLENTY, INDIVIDUALLY; Defendants.

Plaintiffs Metropolitan Life Insurance Company (“MetLife”) and TriNet HR XI, Inc. (“TriNet”) (collectively “Plaintiffs”) seek a preliminary injunction to prevent Durin Mundahl and Morgan Brings Plenty (collectively “Defendants”) from pursuing their action in the Cheyenne River Sioux Tribal Court during the pendency of this case. Doc. 13. Defendants filed a Motion to Stay or Dismiss Action to have this Court defer to the tribal court. Doc. 25. Ruling on these motions requires applying different standards, but the arguments surrounding each considerably overlap. Although principles of comity and tribal exhaustion generally require a federal court to abstain from ruling when there is a pending action in tribal court, these principles do not apply if the proceeding would be patently violative of express jurisdictional prohibitions. Plaintiffs have made a sufficient showing under the Dataphase factors to warrant a preliminary injunction, and a

dismissal or stay of this action is improper due to the apparent lack of tribal court jurisdiction over ERISA-governed plans and suits regarding such plans. I. STANDARDS GOVERNING PENDING MOTIONS A. Preliminary Injunction Factors Plaintiffs seek a preliminary injunction under Rule 65(a) of the Federal Rules of Civil Procedure. “A district court considering injunctive relief evaluates [1] the movant’s likelihood of success on the merits, [2] the threat of irreparable harm to the movant, [3] the balance of the equities between the parties, and [4] whether an injunction is in the public interest.” Powell v. Ryan, 855 F.3d 899, 902 (8th Cir. 2017) (citing Dataphase Sys., Inc. v. C L Sys., Inc., 640 F.2d 109, 114 (8th Cir. 1981) (en banc)). These four considerations are commonly known within the Eighth Circuit as the “Dataphase factors.” “No single factor is dispositive, as the district court must balance all factors to determine whether the injunction should issue. However, in deciding whether to grant a preliminary injunction, likelihood of success on the merits is most significant.” Turtle Island Foods, SPC v. Thompson, 992 F.3d 694, 699 (8th Cir. 2021) (cleaned up and citations omitted). A preliminary injunction is an “extraordinary remedy,” and the burden of establishing that such an injunction should enter rests with the moving party, here the Plaintiffs. Watkins Inc. v. Lewis, 346 F.3d 841, 844 (8th Cir. 2003). B. Motion to Dismiss Standard When considering a motion to dismiss, courts must accept the plaintiffs factual allegations as true and make factual inferences in favor of the plaintiff but need-not accept a plaintiff's legal conclusions. Retro Television Network. Inc. v. Luken Comme’n. LLC, 696 F.3d 766, 768-69 (8th Cir. 2012). To withstand such a motion to dismiss, “a complaint must contain sufficient factual matter, accepted as true, to ‘state a claim to relief that is plausible on its face.’” Ashcroft v. Iqbal,

556 U.S. 662, 678 (2009) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007)). A claim is plausible on its face “when the plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged,” Iqbal, 556 U.S. at 678, “even if it strikes a savvy judge that actual proof of those facts is improbable, and ‘that a recovery is very remote and unlikely,’” Twombly, 550 U.S. at 556 (quoting Scheuer _v. Rhodes, 416 U.S. 232, 236 (1974)). II. PROCEDURAL AND FACTUAL HISTORY- The parties do not dispute many of the core facts. This Court makes no findings of fact at this point and draws the facts from what seems uncontested among Plaintiffs’ Complaint, Defendants’ Complaint in tribal court, Defendants’ “Preliminary Statements of Material Facts,” and documents that the parties reference and attach. Joye M. Braun (“Joye”) was an employee of Indigenous Environmental Network (“TIEN”) and a member of the Cheyenne River Sioux Tribe. Doc. 1-1 J 1; Doc. 23 at 11-12. Plaintiff TriNet . provided human resource services for [EN, including providing group insurance plans, handling payroll, and issuing Joye’s paychecks. See Doc. 23 at 12; Doc. 24-12. Defendants are the natural children of Joye and reside in Eagle Butte on the Cheyenne River Indian Reservation. Doc. 1 3-4; Doc. 1-1 9 1. Joye was married to Floyd Braun! (“Floyd”), but she filed a divorce action in tribal court on October 25, 2022. Doc. 1 § 16; Doc. 11 § 14; Doc. 23 at 14. Floyd may have deserted Joye as early as April 30, 2021. See Doc. 23 at 14. Joye’s listed status on certain TriNet- generated payroll forms apparently was “single.” Id. ,

1 Floyd Braun’s name sometimes appears in the record as Floyd Durin. See Doc. 1 4 16. For clarity, this Court will refer to him as Floyd to prevent confusion with Joye or Defendant Durin Mundahl.

Joye participated in a life insurance and accidental death and dismemberment (“AD&D”) plan (the “Plan”) sponsored by TriNet as a benefit of her employment with IEN and paid premiums by payroll deductions. Doc. 1 410; Doc. 23 at 12. The Plan provided basic life insurance coverage for $40,000 and AD&D coverage for an additional $40,000. Doc. 1 § 12; Doc. 13-1 at 5; Doc. 23 at 12. Plaintiff MetLife is the claim administrator and provider of the benefits under the Plan. Doc. 1 ¢ 13. Joye did not initially designate a beneficiary for her life insurance. Doc. 1 at 915. During an “open season,” Joye submitted a benefit election on November 4, 2022, designating the | Defendants (her biological children) as her life insurance beneficiaries. Doc. 23 at 15; Doc. 24-9 at 2. The parties dispute when the beneficiary designation became effective. Plaintiffs claim its effective date was January 1, 2023, since it was completed during open enrollment. The Open Enrollment Confirmation started “Thank you for submitting your TriNet benefit election for the upcoming benefits plan year (January 1, 2023—December 31, 2023).” Doc. 24-9 at 1. Defendants point to language from the Plan to argue that the designation was immediately effective. The Plan states: “You may change Your Beneficiary at any time. .. . When We receive the change, it will

_ take effect as of the date You signed it.” Doc. 1-2 at 60. Joye died on November 13, 2022. Doe. 1 { 14; Doc. 23 at 16. Her death certificate stated she died from “natural causes,” apparently due to a sudden and unexpected cardiac event. Doc. 1- 2 at 69. The death certificate lists cause of death as “cardiac arrest, COVID 19 infection, hypertensive heart disease,” and the manner of death as “natural causes.” Id. The Plan contained a provision regarding distribution of benefits if no beneficiary is named. Doc. 1-2 at 60. The provision stated: “If there is no Beneficiary designated or no surviving, designated Beneficiary at Your death, We may determine the Beneficiary to be one or more of the

following who survive You: Your Spouse or Domestic Partner; Your child(ren); Your parent(s); or Your sibling(s).” Id. Floyd and Defendants made claim for the life insurance benefits. Doc. 1 {1 17, 19. Metkife paid Floyd $ 40,191.74 in life insurance benefits. Doc. 1 4 18; Doc. 1-2 at 71. The Plan included provisions regarding “ERISA Information” and a “Statement of ERISA Rights.” Doc. 1-2 at 63-68.
