Opinion

UNITED STATES DISTRICT COURT AT TACOMA CYNTHIA R. MACK; JEROLD R. MACK, Case No. 3:25-cv-05244-TMC II, ORDER GRANTING IN PART AND DENYING IN PART MOTION FOR Plaintiffs, SUMMARY JUDGMENT v. USAA CASUALTY INSURANCE COMPANY, Defendant.

I. INTRODUCTION Plaintiffs Jerold Mack and Cynthia Mack move for partial summary judgment against Defendant USAA Casualty Insurance Company (“USAA”), arguing that USAA unreasonably denied them payment of insurance benefits following a car accident with an underinsured motorist. Dkt. 33. They contend that USAA violated the Insurance Fair Conduct Act (“IFCA”), RCW 48.30.015, as well as several provisions of the Washington Administrative Code: WAC 284-30-330(16), 284-30-330(19), 284-30-360(3), and 284-30-580. Id. They also move to exclude defense expert Edward McKinnon on the basis that USAA failed to timely disclose his identity and report. Dkt. 41. For the reasons that follow, the Court concludes that USAA violated IFCA and WAC 284-30-360(3). The Court thus GRANTS IN PART and DENIES IN PART the motion for partial summary judgment (Dkt. 33). The Court further concludes that USAA’s failure to timely

disclose McKinnon merits his exclusion under Federal Rule of Civil Procedure 37(b)(1), and the Court GRANTS the motion to exclude (Dkt. 41). A. Facts This case arises out of a January 4, 2020 car accident between the Macks and another motorist, Alicia Howl. Dkt. 1-1 ¶ 4.1. While Jerold Mack was driving with Cynthia Mack in the passenger seat, Howl’s vehicle struck theirs. Id. Both Jerold and Cynthia Mack sustained injuries from the collision. Dkt. 35-1 at 3; Dkt. 35-2 at 3; see Dkt. 37 at 9. At the time of the accident, Howl was insured under a liability policy issued by Government Employees Insurance Company (“Geico”), with policy limits of $25,000 per person and $50,000 per accident. Dkt. 1-1 ¶ 4.5. The Macks were insured under a USAA policy that provided coverage for underinsured motorist (“UIM”) claims of up to $300,000 per person and $500,000 per accident. Dkt. 34-1 at 3; Dkt. 34-14 at 10, 17–19, 40–43. After the accident, the Macks settled with Geico for $25,000 each, and they opened personal injury protection (“PIP”) and UIM claims with USAA. Dkt. 1-1 ¶¶ 4.6, 4.9. USAA paid the PIP policy limits for each of the Macks. Dkt. 34 ¶ 4. On October 19, 2021, counsel for the Macks sent USAA a settlement demand package for the remaining claims. Dkt. 34-4. On November 2, 2021, USAA responded with initial settlement offers of $125,000 for Jerold Mack’s claim and $75,000 for Cynthia Mack’s claim. Dkt. 38 at 72, 76. Over the following months, the parties negotiated amounts for a potential settlement. Id. at 79–198; Dkt. 34-7; Dkt. 34-9. During this process, USAA considered and accepted medical bills of $63,188 for Jerold Mack and $48,342 for Cynthia Mack. Dkt. 38 at 101, 103; Dkt. 34-17 at 2. USAA’s final counteroffer was $150,000 for each of the Macks. Dkt. 38 at 138–39. USAA reiterated this counteroffer several times and did not later offer a

different amount. Id. at 141, 152, 177, 179. On August 8, 2023, counsel for the Macks sent a letter to USAA demanding payment of the “undisputed benefit funds”—$150,000 each. Dkt. 34-9. On August 20, 2023, USAA emailed the Macks “informing them that $150,000 checks had been issued.” Dkt. 34 ¶ 16; see Dkt. 37 at 7. The same day, USAA sent the Macks a second email informing them that those checks had been canceled. Dkt. 34 ¶ 16. Three days later, USAA sent a letter to counsel for the Macks stating that it would need to “address Medicare” before payment of the “undisputed amount for Mr. Mack” could be issued. Dkt. 34-10. On December 6, 2023, USAA sent another letter indicating that its settlement offer for each of the Macks “remain[ed] at $150,000.00.” Dkt. 34-

12. After counsel for the Macks inquired about payment of the undisputed claim amounts, see Dkts. 34-13, 34-15, USAA responded that it would “issue payment once a settlement is reach[ed].” Dkt. 34-16 at 3; see also Dkt. 34-17 at 2. USAA has not issued the requested payments. Beginning in January 2020 and throughout the ensuing correspondence, counsel for the Macks requested several times that USAA provide a copy of the policy in effect at the time of the accident. Dkt. 34-2; Dkt. 34-9 at 2; Dkt. 34-13 at 2. On May 23, 2024, USAA did so. Dkt. 34-14. B. Procedural history On February 18, 2025, the Macks sued USAA in Pierce County Superior Court. Dkt. 1-1.

On March 20, 2025, USAA removed the case to this court. Dkt. 1. On April 2, 2026, the Macks moved for partial summary judgment. Dkt. 33. USAA responded, and the Macks replied. Dkts. 37, 39. On June 4, 2026, the Macks moved to exclude defense expert Edward McKinnon on the

grounds that USAA did not disclose this witness or his report before the rebuttal expert witness disclosure deadline. Dkt. 41. After the motion was fully briefed (Dkts. 45, 47), the Court issued an order to show cause to resolve the parties’ competing representations about whether McKinnon was timely disclosed. Dkt. 55. Counsel for USAA responded to the order to show cause with a declaration conceding that USAA had not disclosed McKinnon before the deadline. Dkt. 59. Both the motion for partial summary judgment and the motion to exclude are now ripe for the Court’s review. The Court has jurisdiction over this matter under 28 U.S.C. § 1441(a) and 28 U.S.C. § 1332 because the Macks are citizens of Washington, USAA is a citizen of Texas, and the amount in controversy exceeds $75,000. Dkt. 1-1 ¶¶ 1.1, 10.1–10.5; Dkt. 3. IV. LEGAL STANDARD “The court shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). A dispute as to a material fact is genuine “if the evidence is such that a reasonable jury could return a verdict for the nonmoving party.” Villiarimo v. Aloha Island Air, Inc., 281 F.3d 1054, 1061 (9th Cir. 2002) (quoting Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986)). In general, the moving party has the initial burden of “‘showing’—that is, pointing out to the district court—that there is an absence of evidence to support the nonmoving party’s case.” Celotex Corp. v. Catrett, 477 U.S. 317, 325 (1986). If the moving party meets its initial burden, the non-moving party must go beyond the pleadings and “set forth specific facts showing that there is a genuine issue for trial.” Zellmer v. Meta Platforms, Inc., 104 F.4th 1117, 1122 (9th Cir. 2024) (quoting Anderson, 477 U.S. at 256).
