9 Sarah Hager, et al., No. CV-20-02275-PHX-DWL

10 Plaintiffs, ORDER

11 v.

12 United States of America,

13 Defendant. 14 15 In June 2019, Edward Michael Hager (“Hager”) committed suicide one day after 16 seeking mental health counseling at a clinic operated by the Department of Veterans Affairs 17 (“VA”). In this action, Hager’s spouse, Sarah Hager, who is acting on behalf of both herself 18 and the statutory beneficiaries of Hager (collectively, “Plaintiffs”), has sued the United 19 States (“Defendant”) under the Federal Tort Claims Act (“FTCA”), alleging that the nurse 20 who treated Hager at the VA clinic committed malpractice. Now pending before the Court 21 are Defendant’s motion to disqualify Plaintiffs’ standard of care expert (Doc. 49) and 22 Defendant’s motion for summary judgment (Doc. 57). For the following reasons, the 23 former is granted and the latter is denied without prejudice. 24 BACKGROUND 25 I. Relevant Factual Background 26 The following facts are derived from the parties’ submissions and the record 27 evidence and are uncontroverted unless otherwise noted. 28 Hager served in the United States Army from 2002 to 2006. (Doc. 57-1 at 18.) He 1 was deployed to Iraq for 15 months in 2003 and 2004, during which time he “[s]aw friends 2 die, was shot at and sustained several blast injuries and brain concussion [sic].” (Doc. 63 3 at 13.)1 4 Hager’s medical records reveal a series of mental health problems following his 5 return to civilian life. In 2008, he was admitted for inpatient psychiatric care after his wife 6 reported that he had written a suicide note. (Doc. 57-1 at 13.)2 In 2008 or 2009, he began 7 suffering from “paranoia.” (Id.)3 8 On October 27, 2008, Hager underwent a neuropsychological screen. (Doc. 63 at 9 14.) The assessment report from the screen describes Hager’s “verbal and visual memory 10 abilities” as “compromised.” (Id. at 15 [“Retention of both verbal and visual information 11 following a brief delay was severely impaired . . . .”].) The report also notes that Hager 12 reported a variety of psychiatric symptoms (e.g., hypervigilance, frequent nightmares, and 13 significant irritability) but that, “[i]nterestingly, when later asked to fill out self report 14 measures of mood symptoms, his endorsement indicated only mild symptoms of 15 depression and anxiety. . . . Inconsistency in . . . reports likely indicates that the inventories 16 represent an underestimation of his current symptoms.” (Id. at 16.) 17 On November 10, 2008, Hager saw a psychiatrist for symptoms related to post- 18 traumatic stress disorder (“PTSD”) and traumatic brain injury. (Id. at 12-13.) At that time, 19 1 Plaintiffs submitted a separate statement of facts in support of their opposition to 20 Defendant’s summary judgment motion. (Doc. 63.) This approach was improper under the scheduling order: “Local Rule of Civil Procedure 56.1 is suspended, except for 21 subsection (d). The Court will decide summary judgment motions under Federal Rule of Civil Procedure 56 only. In other words, the parties may not file separate statements of 22 facts or separate controverting statements of facts, and instead must include all facts in the motion, response, or reply itself. All evidence to support a motion or response that is not 23 already part of the record must be attached to the briefs.” (Doc. 13 at 5.) Based on the scheduling order, Defendant asks the Court to strike Doc. 63 under Rule 12(f). (Doc. 68 24 at 1-2.) The Court declines to do so—because Plaintiffs’ exhibits were attached to the separate document, the Court will overlook the procedural misstep. 25 2 Hager described this incident to a medical provider in 2013 but stated he did not recall writing the note. (Doc. 57-1 at 13.) 26 3 The medical notes from the 2013 visit provide: “[Hager] states he’s had paranoia 27 since 08-09 when he was deployed . . . .” (Doc. 57-1 at 13.) This chronology appears to be inaccurate, as Hager was deployed during 2003 and 2004 and was discharged in 2006. 28 It is therefore possible that the paranoia began before 2008. This distinction is not material to the analysis here. 1 Hager was experiencing “nightmares of combat,” trouble sleeping, anxiety about crowds, 2 and “flashbacks when . . . driving.” (Id. at 13.) 3 On June 17, 2013, Hager presented at a VA clinic in Phoenix and reported suffering 4 from “increasing paranoia” and sleep deprivation. (Doc. 57-1 at 13.) The paranoia 5 included suspicions that his wife was cheating on him, “thoughts that his boss [was] not 6 calling him,” and “paranoia that the authorities are watching him because of a DVD of 7 possible pornography that didn’t belong to him and he thinks was planted on him.” (Id.) 8 Hager also thought “he was poisoned as he had blood in his urine and stool and chest pain.” 9 (Id. at 18.)4 However, he denied past or present suicidal ideations. (Id. at 16-17.) The 10 provider determined that Hager was “[a]dequate for outpatient treatment.” (Id. at 15. See 11 also id. at 22 [stating that Hager’s screening assessment was “suggestive of moderately 12 severe depression”].) Hager was scheduled to see a psychiatrist within the following two 13 weeks. (Id. at 5 ¶ 12.) However, he did not keep the appointment. (Id.) 14 Six years later, on June 24, 2019, Hager presented as a walk-in patient at the VA’s 15 Willow Clinic in Gilbert, Arizona and requested counseling services. (Id.at 4 ¶ 4, 6 ¶ 14.) 16 A medical support assistant took Hager’s vital signs and “administered the Patient Health 17 Questionnaire (PHQ-2+I9), which is the standard depression and primary suicide risk 18 screen,” and “the standard PTSD and primary suicide risk screen (PC-PTSD-5+I9).” (Id. 19 at 4 ¶ 7, 6 ¶¶ 16-17.) Hager scored “negative for risk of suicide over the previous two 20 weeks” on both screens. (Id. at 6 ¶¶ 16-17.) 21 Next, Hager was seen by the triage nurse. (Id. at 4 ¶¶ 4-5.) At that time, William 22 Weishaar (“Nurse Weishaar”) worked as the regular triage nurse at Willow Clinic. (Doc. 23 63 at 25.) When Nurse Weishaar wasn’t working, “[t]he other nurses in the Willow Clinic 24 rotated to cover [the] triage position.” (Doc. 57-1 at 4 ¶ 5.) On June 24, 2019, Vicky 25 Markey (“Nurse Markey”) was covering triage. (Id.) At all relevant times, Nurse Markey 26

27 4 The day before, on June 16, 2013, Hager presented at an emergency room with chest pain. (Doc. 57-1 at 18; Doc. 63 at 11.) The notes from that visit indicate a friend reported 28 that Hager’s wife was due to deliver their first baby on June 15, 2013, and that Hager believed the baby’s sex had been changed inside the womb. (Doc. 63 at 11.) 1 worked as a mental health nurse at Willow Clinic. (Id. at 3 ¶ 3.) 2 During the June 24, 2019 consultation with Nurse Markey, Hager requested 3 counseling, explaining: “I am feeling anxious and need some counseling. My wife and 4 kids are gone for two weeks and I don’t know what to do with myself.” (Id. at 26.) He 5 also reported that he had “hardly slept in days” and “hate[d] being alone and in [his] own 6 head.” (Id. at 26.) Hager also mentioned that he had recently stopped running a website 7 for veterans because it was getting too “dark” and “bringing up past memories” and that, 8 as a result, he had “too much time on his hands and [was] thinking too much . . . .” (Id.) 9 Nurse Markey “administered the Columbia Suicide Severity Rating Scale (C- 10 SSRS), a standard suicide screening tool widely used in the mental health and primary care 11 settings, and completed a suicide risk assessment (SRA), which is a clinical evaluation to 12 determine the nature and degree of suicide risk/probability.” (Id. at 6-7 ¶ 20.) “The 13 C-SSRS and SRA indicated that Mr. Hager was at low risk for suicide.” (Id. at 7 ¶ 20.) In 14 relevant part, Hager reported that in the past month, “he had never wished that he was dead 15 or that he could go to sleep and not wake up,” did not have “any actual thoughts of killing 16 himself,” and had not considered suicide, and that in his lifetime, he had never prepared or 17 attempted to commit suicide. (Id. at 7 ¶¶ 21-23.) Nurse Markey then asked Hager “whether 18 he had firearms in his home” and, if so, whether “he would consider removing his firearms 19 from his residence.” (Id. at 7 ¶¶ 24-25.) Hager “agreed to take [his firearms] to his father’s 20 house, stating ‘I am not suicidal or anything but it can only be a smart move to get them 21 out of my house.’” (Id. at 7 ¶ 25.) Hager also represented that “he intended to stay with 22 his father while his family was out of town.” (Id.) 23 Nurse Markey “scheduled Mr. Hager for an appointment with . . . a psychiatrist at 24 the Willow Clinic on July 24, 2019.” (Id. at 9 ¶ 40.) She also provided him with 25 information about other VA resources, including the Mesa Vet Center, “a small, non- 26 medical counseling center staffed by counselors [that] offers on[e]-on-one counseling and 27 group sessions.” (Id. at 10 ¶¶ 43, 45-47. See also id. at 10 ¶ 45 [“I also gave Mr. Hager 28 information about the emergency services available through the VA and instructed him to 1 call 911 or the Veterans Crisis Line if he was having thoughts of suicide or homicide or 2 was otherwise in mental distress.”].) 3 After the consultation with Nurse Markey, Hager called his father and asked if his 4 parents “would stop by after work to pick up his weapons.” (Id. at 40.) Around 5:00 PM, 5 Hager’s parents went to his house. (Id.) During the visit, Hager told his mother that the 6 VA had “suggested that a family member take his weapons.” (Id. at 41.) His father 7 retrieved the guns, which were “all packed up” in a bag, from the master bedroom. (Id. at 8 41-43.) After about an hour and a half, his parents left. (Id. at 42.) 9 The following day, Hager was found dead in his home from a self-inflicted gunshot 10 wound. (Id. at 50.) 11 II. Procedural History 12 On November 24, 2020, Plaintiffs initiated this action. (Doc. 1.) 13 On April 22, 2021, the Court set discovery deadlines, including: (1) October 22, 14 2021 for Plaintiffs’ expert disclosures; (2) January 21, 2022 for rebuttal expert disclosures; 15 and (3) March 11, 2022 for expert depositions. (Doc. 13 at 3.) Some of these deadlines 16 were later extended at the parties’ joint request. (Docs. 29, 38.) 17 On July 1, 2022, after the expiration of the deadlines for the completion of expert 18 and fact discovery and Rule 26(a)(3) pretrial disclosures (see Doc. 45), Defendant moved 19 to disqualify Plaintiffs’ standard of care expert. (Doc. 49.) On July 29, 2022, Defendant 20 moved for summary judgment. (Doc. 57.) Both motions are now fully briefed. (Docs. 58, 21 60, 62, 63, 66, 68.) 22 On January 27, 2023, the Court issued a tentative ruling. (Doc. 70.) 23 On February 13, 2023, the Court heard oral argument. (Doc. 71.) 24 DISCUSSION 25 “The Federal Tort Claims Act (FTCA) allows a plaintiff to bring certain state-law 26 tort suits against the Federal Government.” Brownback v. King, 141 S. Ct. 740, 745 (2021). 27 See also 28 U.S.C. §§ 1346(b)(1), 2674. Here, Plaintiffs assert three FTCA claims based 28 on Arizona’s law of medical malpractice: medical negligence, wrongful death, and 1 vicarious liability. (Doc. 1 ¶¶ 1, 50-69.)5 2 I. Disqualification Of Plaintiffs’ Expert 3 Plaintiffs disclosed Boulay Bala, a registered nurse (“Nurse Bala”), as their expert 4 witness on the standard of care. (Doc. 58-6.) Defendant moves to disqualify Nurse Bala 5 and, based in part on that disqualification, moves for summary judgment. The issues 6 addressed in the two motions substantially overlap and both sides raise disqualification 7 arguments in their summary judgment submissions that were not raised (or, at least, not 8 raised in such clear terms) in relation to the motion to disqualify. For clarity and efficiency, 9 the Court has attempted to integrate the disqualification arguments from all of the parties’ 10 submissions into one, cohesive analysis. 11 A. Legal Standard 12 Rule 601 of the Federal Rules of Evidence provides that “[e]very person is 13 competent to be a witness unless these rules provide otherwise. But in a civil case, state 14 law governs the witness’s competency regarding a claim or defense for which state law 15 supplies the rule of decision.” Id. See also Higgenbottom v. Noreen, 586 F.2d 719, 722 16 (9th Cir. 1978) (“The competence of witnesses is for the court to decide in accordance with 17 state law if state law ‘supplies the rule of decision.’”). FTCA claims are “governed by the 18 substantive law of the place where the act or omission complained of occurred.” Yako v. 19 United States, 891 F.2d 738, 745 (9th Cir. 1989). See also 28 U.S.C. § 1346(b)(1). 20 Accordingly, Arizona law governs whether Nurse Bala is qualified to render 21 standard-of-care opinions here. 22 Under Arizona law, “[e]xperts testifying to the standards of care of medical 23 professionals must satisfy . . . the ‘heightened’ requirements of A.R.S. § 12-2604.” 24 Windhurst v. Ariz. Dep’t of Corr., 501 P.3d 752, 755-56 (Ariz. Ct. App. 2021), review 25 granted (2022). See also Seisinger v. Siebel, 203 P.3d 483, 493 (Ariz. 2009) (noting that 26

27 5 Section 12-561(2) of the Arizona Revised Statutes defines “Medical malpractice action” as “an action for injury or death against a licensed health care provider based upon 28 such provider’s alleged negligence, misconduct, [or] errors or omissions in the rendering of health care, medical services, nursing services or other health-related services . . . .” 1 “§ 12-2604(A) provides that certain expert testimony cannot be received” and “is 2 substantive insofar as it requires a certain type of evidence to prove an element of the tort”); 3 Wright v. United States, 2008 WL 820557, *4 (D. Ariz. 2008) (for FTCA medical 4 malpractice claims where substantive Arizona law applies, Federal Rule of Evidence 601 5 “requires witness competency to be determined by Arizona law, including A.R.S. 6 § 12-2604”). 7 B. The Parties’ Arguments 8 Defendant moves to disqualify Nurse Bala, “[t]he expert witness disclosed by 9 Plaintiffs to opine that Nurse Markey fell below the standard of care in her treatment of 10 Mr. Hager.” (Doc. 49 at 2.)6 Defendant asserts that Nurse Markey is a “licensed registered 11 nurse and is board-certified in psychiatric-mental health nursing (PMH-BC) by” the 12 American Nurses Credentialing Center (“ANCC”) and the “care at issue is specialty . . . 13 mental health care.” (Id. at 5.) Defendant notes that Nurse Bala is not, in contrast, board 14 certified in that specialty. (Id.) Thus, Defendant argues that under A.R.S. § 12-2604, 15 Nurse Bala is not qualified to provide expert testimony establishing the standard of care 16 applicable to Nurse Markey. (Id. at 2-5.)7 17 In response, Plaintiffs argue that Defendant “failed to provide evidence that Nurse 18 Markey is actually certified as she so claims.” (Doc. 58 at 1-2.) In a related vein, Plaintiffs 19 argue that Nurse Markey received her certification from a credentialling center, not a 20 medical board, and is thus not board certified for purposes of A.R.S. § 12-2604(A)(1). (Id. 21 at 2.) Plaintiffs elaborate that Nurse Markey merely “took a test provided by a 22 clearinghouse certification center and had enough years in mental health care to be able to 23 purchase a certificate for her wall that may entitle her to a pay raise in certain 24 organizations.” (Doc. 62 at 4-5.) Next, Plaintiffs argue that their lawsuit alleges that Nurse 25 6 In a footnote, Defendant also challenges the sufficiency of a report by Dr. Thomas 26 Joiner, Jr., Plaintiffs’ rebuttal expert, but does not request any relief from the Court in relation to that challenge. (Doc. 49 at 2 n.1.) 27 7 In its motion for summary judgment, Defendant “incorporates the arguments made 28 in its Motion to Disqualify Plaintiffs’ Standard of Care Expert” and “re-urges the Court to disqualify Nurse Bala.” (Doc. 57 at 6.) 1 Markey’s “work at the triage desk . . . was below the standard of care of a triage nurse,” 2 not of a mental health nurse, and thus “[h]er certification in clinical practice is not at issue.” 3 (Doc. 58 at 2.) Next, Plaintiffs argue that if Nurse Bala is disqualified, Nurse Weishaar, 4 the regular triage nurse, has provided testimony that establishes Nurse Markey fell below 5 the standard of care. (Id.) Finally, and in the alternative, “Plaintiffs request that this Court 6 permit them to substitute Nurse Rebecca Puchkors as their standard of care expert.” (Id.) 7 In reply, Defendant contends the record evidence establishes that Nurse Markey is 8 “board certified as a Psychiatric Mental Health Nurse.” (Doc. 60 at 1-2.) Defendant notes 9 that the ANCC is “accredited by the Accreditation Board for Specialty Nursing 10 Certification (ABSNC),” which is “the only accrediting body specifically for nursing 11 certification.” (Id. at 2.) After summarizing the requirements an applicant seeking to 12 become a PMH-BC must fulfill, Defendant argues that “[o]btaining a certification from a 13 program accredited by ABSNC is a registered nurse’s equivalent to a physician’s 14 certification from a medical specialty board.” (Id. at 2-3.) As for whether Nurse Markey 15 was working within her specialty when she treated Hager, Defendant explains that although 16 Nurse Markey was “covering for the mental health clinic’s triage nurse” on the day in 17 question, the only difference between the care provided by the triage nurse and that 18 provided by Nurse Markey as a psychiatric mental health nurse is that the triage nurse sees 19 “walk-in mental health patients instead of patients with previously scheduled 20 appointments.” (Id. at 3.) Finally, Defendant argues that Nurse Weishaar cannot testify as 21 to Nurse Markey’s standard of care because, like Nurse Bala, he is “not board certified in 22 psychiatric and mental health nursing.” (Id. at 4.) At any rate, Defendants contend that 23 Nurse Weishaar’s testimony “does not establish the standard of care.” (Id.) 24 C. Analysis 25 Section 12-2604(A) of the Arizona Revised Statutes requires a person giving expert 26 testimony on the appropriate standard of practice or care in an action alleging medical 27 malpractice to be “licensed as a health professional in this state or another state.” The 28 statute provides that such an expert also must meet the following criteria: 1 If the party against whom or on whose behalf the testimony is offered is or claims to be a specialist, specializes at the time of the occurrence that is the 2 basis for the action in the same specialty or claimed specialty as the party against whom or on whose behalf the testimony is offered. If the party 3 against whom or on whose behalf the testimony is offered is or claims to be a specialist who is board certified, the expert witness shall be a specialist who 4 is board certified in that specialty or claimed specialty. 5 Id. § 12-2604(A)(1). Based on this language, the Arizona Supreme Court has provided the 6 following framework for applying § 12-2604: “The court must initially determine if the 7 care or treatment at issue involves the identified specialty, which may include recognized 8 subspecialties. If it does, testifying experts must share the same specialty as the treating 9 physician. The trial court then must determine if the treating physician is board certified 10 within that specialty. If so, any testifying expert must also be board certified in that 11 specialty.” Baker v. Univ. Physicians Healthcare, 296 P.3d 42, 49 (Ariz. 2013). See also 12 id. at 46 (“[T]he statute does not define the terms ‘specialist’ or ‘board certified,’ and 13 Arizona law does not otherwise provide general definitions for these terms.”). 14 Here, the parties dispute (1) whether the treatment at issue involved an “identified 15 specialty” (i.e., psychiatric mental health nursing); and (2) whether Nurse Markey was 16 “board certified within that specialty.” 17 1. Identified Specialty 18 Defendant contends that “[w]hen Nurse Markey treated Mr. Hager she was 19 rendering care within the scope of her board certification” as a psychiatric mental health 20 nurse. (Doc. 49 at 5. See also id. [“The care at issue is specialty care – that is, mental 21 health care.”].) To support its position, Defendant references paragraphs 43 through 49 of 22 the complaint, which allege, in relevant part: 23 [Hager] went to the VA on June 24, 2019, and reported the following: A. He 24 was anxious and in need of counseling; B. His wife and kids were gone and he “didn’t know what to do with himself;” C. His thoughts were “getting too 25 dark [and] bringing up past memories;” and D. He had “too much time on his hands,” and he was “thinking too much.” . . . He also reported having 26 firearms at his house. . . . Instead of providing any services to [Mr. Hager], the VA provider told [Hager] to give his guns to a family member and come 27 back in thirty days for a counselling session. . . . As a direct and proximate result of the Phoenix VA healthcare providers breaching the applicable 28 standard of care, [Hager] committed suicide . . . . 1 (Doc. 1 ¶¶ 43-47.) 2 Plaintiffs argue that, although Nurse Markey was certified in the “practice of clinical 3 mental health care,” the complaint challenges “her work at the triage desk[,] which is not 4 clinical mental health care.” (Doc. 58 at 2. See also id. at 8 [“At the time she refused to 5 provide [Hager] with a counsellor to talk to – as [he] requested – Nurse Markey was simply 6 filling in for the normal triage nurse.”].) Plaintiffs contend that “[e]valuating someone in 7 triage is not the same as providing clinical care” and note that the regular triage nurse “does 8 not have a certification in clinical care.” (Id. at 7-8.) 9 In reply, Defendant asserts that the triage nurse is “assigned solely to the mental 10 health clinic” and sees “walk-in mental health patients.” (Doc. 60 at 3.) According to 11 Defendant, “the care provided was the same whether the patient was a walk-in patient [seen 12 by the triage nurse] or an established patient [seen by a psychiatric nurse].” (Id.) Thus, 13 Defendant argues that the mere fact Nurse Markey provided psychiatric mental health care 14 to Hager as a walk-in patient (rather than as a patient with a scheduled mental health 15 appointment) has no bearing on whether Nurse Markey was “practicing within her 16 specialty as a psychiatric mental health nurse.” (Id. at 3-4.) 17 “[A]n expert must establish the same specialization as the health care provider under 18 § 12-2604(A) when the care or treatment at issue was within that specialty.” Rasor v. Nw. 19 Hosp., LLC, 403 P.3d 572, 577 (Ariz. 2017) (internal quotation marks omitted). For 20 purposes of § 12-2604, “specialty” means “a limited area of medicine in which a physician 21 is or may become board certified.” Baker, 296 P.3d at 48. Whether the care or treatment 22 at issue involves a certain specialty or subspecialty “will depend on the circumstances of a 23 particular case.” Id. at 49. 24 The Court agrees with Defendant that Nurse Markey was acting within her specialty 25 as a psychiatric mental health nurse when she treated Hager. Nurse Markey encountered 26 Hager as a walk-in patient at a VA mental health clinic. (Doc. 57-1 ¶ 3 [Markey 27 declaration, describing the Willow Clinic as a VA “outpatient mental health care clinic”].) 28 After Hager requested counseling, Nurse Markey evaluated Hager’s suicide risk level and 1 psychiatric treatment needs using several assessment tools, discussed various mental health 2 safety strategies, and scheduled Hager for a counseling appointment. (Doc. 57-1 at 3-11 3 [Markey declaration].) Defendant asserts this care is effectively identical to what Hager 4 would have received had he been treated by Nurse Markey in her normal capacity as a 5 psychiatric nurse (Doc. 60 at 3) and the record evidence supports this assertion. (Doc. 49- 6 1 at 3 [Markey resume, explaining Markey’s duties as a psychiatric nurse]; Doc. 57-1 at 2 7 ¶¶ 6-9 [Markey declaration, explaining the process for assessing walk-in patients]; Doc. 8 60-1 at 12-16 [Weishaar deposition, same]). Plaintiffs’ attempt to distinguish between 9 “triage” and “clinical care” is unconvincing—Plaintiffs provide no evidence that triage and 10 clinical care are different “specialties” within the meaning of § 12-2604, at least with 11 respect to the Willow Clinic. See also Harrelson v. Dupnik, 2014 WL 2510530, *9 (D. 12 Ariz. 2014), report and recommendation adopted as modified, 2014 WL 2510569 (D. Ariz. 13 2014) (“[W]hether or not there is a specialty involved in being a provider or medical 14 director . . . is not the relevant inquiry. What is relevant is whether the care or treatment at 15 issue involves an identified specialty.”). 16 The fact that Nurse Weishaar (the regular triage nurse) was not certified in 17 psychiatric mental healthcare is of no consequence. Section 12-2604 “requires a testifying 18 expert to be certified in the board-certified treating physician’s specialty, even if physicians 19 in other specialties might also have competently provided the treatment and even though 20 different specialists may be prepared by training and experience to treat the same medical 21 issue for a particular patient.” Genovese v. Bodynew Inc, 2018 WL 2355188, *3 (Ariz. Ct. 22 App. 2018) (internal quotation marks omitted). See also Preszler v. Corwin D. Martin PC, 23 2022 WL 175568, *3 (Ariz. Ct. App. 2022), review denied (2022) (“Even though [Plaintiff] 24 asserts that a periodontist and oral and maxillofacial surgeon could have treated [Plaintiff], 25 Martin was practicing within his board-certified specialty of oral and maxillofacial surgery 26 at the time he rendered treatment to [Plaintiff]. . . . Accordingly, Section 12-2604 required 27 [Plaintiff’s expert] to be certified in that same specialty . . . .”). 28 … 1 2. Board Certification 2 Because Nurse Markey was acting within her specialty as a psychiatric mental 3 health nurse when she saw Hager, the requirements of A.R.S. § 12-2604(A)(1) apply. 4 Baker, 296 P.3d at 47. Section 12-2604(A)(1) provides, in relevant part: “If the party 5 against whom . . . the testimony is offered is or claims to be a specialist who is board 6 certified, the expert witness shall be a specialist who is board certified in that specialty or 7 claimed specialty.” 8 Here, Nurse Markey’s resume describes her as a “RN-BC (board certified in 9 psychiatric and mental health nursing).” (Doc. 49-1 at 3.) On October 12, 2021, during 10 her deposition, Nurse Markey testified that she is “certified in psychiatric and mental health 11 through the American Nursing (sic) Credentialing Center.” (Id. at 12-13. See also id. at 12 13 [describing the certification process].) In July 2022, Plaintiffs’ counsel obtained a letter 13 from the ANCC verifying that, at all relevant times, Nurse Markey was certified as a 14 Psychiatric Mental Health Nurse–Board Certified (“PMH-BC”) by the ANCC. (Doc. 58- 15 12 ¶¶ 6, 9.) 16 In contrast, Nurse Bala is licensed as a Registered Nurse and a Public Health Nurse. 17 (Doc. 49-1 at 26; Doc. 63 at 33.) As of October 22, 2021, Nurse Bala worked as an “RN 18 Administrative Supervisor in the Acute Psychiatric Behavioral Health Center at John Muir 19 Health in Concord, California.” (Doc. 63 at 33.) “In the year preceding the events in 20 question, [Nurse Bala] was in full-time active clinical practice as a staff Registered 21 Nurse/Lead Nurse in the Acute Psychiatric/Mental Health Unit of St. Helena Hospital in 22 St. Helena, California . . . .” (Id.) Nurse Bala’s resume does not indicate any certification 23 in psychiatric or mental health nursing (Doc. 49-1 at 26) and in a deposition on May 17, 24 2022, Nurse Bala stated that she is not “board certified in any particular practice area” (id. 25 at 21). 26 The parties agree that Nurse Bala is not board certified in psychiatric mental health 27 nursing. Thus, Plaintiffs’ arguments focus on whether Nurse Markey is board certified 28 such that § 12-2604 would require Nurse Bala to have the same certification. First, 1 Plaintiffs contend there is no “evidence that Nurse Markey is actually certified as she so 2 claims.” (Doc. 58 at 1.) This contention is belied by the record. Nurse Markey testified 3 that she is “certified in psychiatric and mental health” through the ANCC (Doc. 49-1 at 4 12-13) and provided an affidavit describing herself as “a licensed registered nurse 5 board-certified in psychiatric and mental health nursing by the American Nurses 6 Credentialing Center” (Doc. 57-1 at 3 ¶ 2). Moreover, a paralegal for Plaintiffs’ counsel 7 states, in an affidavit, that Plaintiffs’ counsel received a “verification letter” from the 8 ANCC in July 2022 stating that Nurse Markey has a “PMH-BC” certification. (Doc. 58- 9 12 ¶ 9.) Accordingly, the record establishes Nurse Markey’s certification. 10 Plaintiffs next contend that Nurse Markey is not board certified because she merely 11 “paid for a certificate after taking a short test through a credentialling center.” (Doc. 58 at 12 2. See also id. at 7 [“Because the ANCC is not a medical board, Markey cannot be 13 considered ‘board certified.’”].) Plaintiffs contrast Nurse Markey’s ANCC certification 14 with specialty certifications for physicians from the American Board of Medical Specialties 15 (“AMBS”), arguing that Nurse Markey did not fulfill the AMBS requirements for board 16 certification and that her “certificate in the ‘clinical knowledge and skills of registered 17 nurses in the psychiatric-mental health specialty after initial RN licensure’” is not 18 comparable. (Id. at 6-7.) In reply, Defendant argues that the ANCC “is accredited by the 19 Accreditation Board for Specialty Nursing Certification (ABSNC), . . . the only accrediting 20 body specifically for nursing certification.” (Doc. 60 at 2, quotation marks omitted.) 21 Defendant further notes that to become certified through the ANCC as a PMH-BC, an 22 applicant must hold a current, active license as a registered nurse, have “practiced for the 23 equivalent of two years as a full-time registered nurse,” have at least 2,000 hours of 24 “clinical practice in psychiatric-mental health nursing” within the past three years, and 25 complete 30 hours of continuing education in the specialty. (Id.) 26 The Court concludes that Nurse Markey’s PMH-BC credential from the ANCC is a 27 “board certification” for purposes of § 12-2604. Plaintiffs make much of the fact that the 28 ANCC “is not—as its name states—a medical board.” (Doc. 58 at 7. See also id. 1 [distinguishing between a “credentialling center” and a “medical board”].) But even if the 2 ANCC is not a literal board,8 a nurse certified by the ANCC may be considered “board 3 certified” within the meaning of § 12-2604. As noted by Defendant, the ANCC is 4 accredited by the ABSNC, which is an accreditation board. (Doc. 60 at 2.) Screenshots of 5 the ANCC’s website, attached to Plaintiff’s response, refer to “ANCC board certification.” 6 (Doc. 58-13 at 4, emphasis added.) The attached webpage explaining how to obtain a 7 PMH-BC describes the certification as “ANCC Psychiatric-Mental Health Nursing board 8 certification.” (Id. at 8.) Notably, it also indicates that the “BC” in “PMH-BC” stands for 9 “Board Certified.” (Id.) This evidence is sufficient to establish that Nurse Markey’s 10 certification in PMH-BC from the ANCC was a board certification for purposes of 11 § 12-2604(A)(1). 12 The fact that ANCC certification “is not the same as a physician’s specialty 13 board-certification, which typically requires the completion of both medical school and a 14 residency program” (Doc. 58-14), does not mean that ANCC certification isn’t board 15 certification for purposes of § 12-2604. By its plain terms, § 12-2604(A) applies to a 16 “person licensed as a health professional.” Arizona courts have repeatedly applied the 17 statute to nurses and other non-physician healthcare professionals, none of whom had a 18 “physician’s specialty board certification.” See, e.g., Trujillo v. United States, 2018 WL 19 1729345, *3 (D. Ariz. 2018), aff’d, 786 F. App’x 124 (9th Cir. 2019) (applying 20 § 12-2604(A)(1) to a physician’s assistant); Atencio v. Arpaio, 2015 WL 11117187, *6 21 (D. Ariz. 2015) (applying § 12-2604(A)(1) to a licensed clinical social worker and a 22 licensed professional counselor); Cornerstone Hosp. of Se. Ariz., L.L.C. v. Marner, 290 23 P.3d 460, 472 (Ariz. Ct. App. 2012) (holding that nursing qualifies as a “health profession” 24 for purposes of § 12-2604(A)(2)). As the statute’s language makes clear, § 12-2604 does 25 not require the board certification to be a physician board certification. To the extent the 26 Baker court defined “specialty” in terms of board certification for physicians, this 27

28 8 The Court notes that the only evidence Plaintiffs provide to establish that the ANCC is not a “board” is the fact that the word “board” is not in its name. (Doc. 58 at 7.) 1 definition is inapplicable where, as here, the relevant standard for care is that of a 2 psychiatric mental health nurse. Thus, Plaintiffs’ assertion that a physician’s board 3 certification and an ANCC certification are distinct (because the former requires certain 4 “years of training”) is unavailing.9 See also St. George v. Plimpton, 384 P.3d 1243, 5 1247-48 (Ariz. Ct. App. 2016) (“[B]ecause Nurse Franklin is certified by the ASBN as a 6 certified nurse midwife, any standard of care expert testifying against her must likewise be 7 a certified nurse midwife.”).10 8 To summarize, Nurse Markey was, at all relevant times, a registered nurse who was 9 board certified in “psychiatric mental health nursing” by the ANCC. Nurse Bala does not 10 have the equivalent certification. Thus, because Nurse Markey was working within this 11 specialty when she treated Hager, Nurse Bala is not qualified to provide expert testimony 12 on the appropriate standard of care applicable to Nurse Markey. Accordingly, the Court 13 grants Defendant’s request to exclude Nurse Bala as Plaintiffs’ standard of care expert. 14 3. Substitution 15 In response to both of the pending motions, Plaintiffs “request that this Court permit 16 them to substitute Nurse Rebecca Puchkors as their standard of care expert.” (Doc. 58 at 17 2; Doc. 62 at 4-5.) Nurse Puchkors is a registered nurse with a PMH-BC certification from 18 the ANCC. (Doc. 58-2 at 1.) 19 Defendant contends that “Plaintiffs should not be given additional time to secure a 20 qualified standard of care expert” because they “did not seek additional time to secure a 21 standard of care expert who was board certified in psychiatric-mental health nursing before 22 producing their expert reports although they knew at that time that Nurse Markey was 23 board certified.” (Doc. 49 at 6.) 24 9 Plaintiffs also provide no evidence to support this assertion. (See generally Docs. 25 58-1 through 58-14.) 26 10 Under Arizona regulations, a certified nurse midwife may be certified “by a nursing certification organization accredited by the Accreditation Board for Specialty Nursing 27 Certification, the National Commission for Certifying Agencies, or an equivalent accrediting agency as determined by the Board.” Ariz. Admin. Code § R4-19-310. See 28 also A.R.S. § 32-1601(5) (defining “certified nurse midwife”). The ANCC is also accredited by the ABSNC. (Doc. 60 at 2.) 1 Plaintiffs respond that substitution is warranted because they “spent half a year 2 trying to get [Nurse] Markey’s credentials,” Nurse Markey “never testified that she had a 3 board certification,” and “the first mention of a purported ‘board’ came a day before the 4 Plaintiffs’ expert disclosure.” (Doc. 58 at 9.) Plaintiffs also note that “witness 5 qualifications were the basis for motion-work at the beginning of this year” and argue that 6 “Defendant needlessly delayed in filing this pending motion.” (Id.)11 Based on these facts, 7 Plaintiffs contend that the factors considered by the Arizona Supreme Court in Rasor weigh 8 in favor of allowing substitution. (Id.)12 9 In reply, Defendant contends that Plaintiffs’ “first proper request” for Nurse 10 Markey’s credentials occurred on September 17, 2021 and it timely responded to that 11 request on October 20, 2021 with Nurse Markey’s resume, which describes her as “board 12 certified in psychiatric and mental health nursing.” (Doc. 60 at 5.)13 Additionally, 13 Defendant notes that Plaintiffs’ counsel “did not ask . . . whether [Nurse Markey] had any 14 certifications or specializations” when he deposed Nurse Markey on October 12, 2021— 15 instead, “that testimony was elicited by defense counsel.” (Id.) Accordingly, Defendant 16 contends that “Plaintiffs were aware that Nurse Markey was certified in psychiatric and 17 mental health nursing by the ANCC” before October 22, 2021, the deadline for Plaintiffs 18 to disclose expert witnesses, yet “Plaintiffs did not seek additional time to secure a similarly 19 qualified expert, despite moving for additional time to secure a rebuttal expert with defense 20 counsel’s consent.” (Id. at 6.) As for the timing of the disqualification motion, Defendant 21 contends it “was not aware that Nurse Bala was not board certified in psychiatric and 22 mental health nursing . . . until she was deposed on May 17, 2022” and then “moved to 23 disqualify her on July 1, 2022, the date set in the Case Management Order for motions 24 11 Plaintiffs’ contention that Defendant “is not seeking any sort of case-dispositive 25 relief” (Doc. 58 at 9) is inaccurate in light of Defendant’s motion for summary judgment (Doc. 57). 26 12 In their response to Defendant’s motion for summary judgment, Plaintiffs suggest that “[i]t may even be an abuse of discretion not to allow the substitution.” (Doc. 62 at 4 27 n.1.) 28 13 Defendant reiterates this point in its reply in support of summary judgment. (Doc. 68 at 3.) 1 challenging expert testimony.” (Id.) Finally, Defendant contends that if substitution is 2 allowed, it should “be given an opportunity to depose the new expert . . . [and] have its 3 expert address the new expert’s opinions.” (Doc. 68 at 3 n.1.) 4 “Although ordinarily ‘a plaintiff’s failure to provide a qualified standard-of-care 5 expert would justify summary judgment for the defense,’ the Court may deny summary 6 judgment and allow the plaintiff to nominate a new expert where the plaintiff properly 7 seeks relief under Rule 56(d).” Ellsworth v. United States, 2018 WL 1784687, *4 (D. Ariz. 8 2018) (citation omitted).14 “In determining whether to grant such relief, the Court 9 considers ‘both the good faith or lack thereof of the plaintiff in proposing the initial expert 10 whose qualifications are questioned on summary judgment, as well as the defendant’s 11 waiting to challenge the proposed expert until this later stage of litigation . . . if the 12 qualifications were plainly inadequate in the affidavit.’” Id. (quoting Rasor, 403 P.3d at 13 577). 14 Here, the following facts provide context for Plaintiffs’ substitution request. On 15 May 10, 2021, Plaintiffs’ counsel emailed defense counsel, stating, in relevant part: “I am 16 very interested in knowing the particulars of the board certification in Nurse Markey’s title. 17 We have assumed it is a mental health specialization, but I can’t find anything online. Can 18 you ask right away so can address that with my experts?” (Doc. 58-5 at 1-2.) On June 10, 19 2021, Plaintiffs’ counsel sent Nurse Bala’s “expert witness affidavit” to defense counsel. 20 (Doc. 58-6 at 1.) The affidavit described Nurse Bala as “Registered Nurse and a Public 21 Health Nurse,” “educated in acute psychiatric care and intervention.” (Id. at 2 ¶ 1.) The 22 affidavit also indicated that Nurse Bala’s resume was attached. (Id.) Nurse Bala’s resume, 23 in turn, provides Nurse Bala’s “licenses and certifications.” (Doc. 49-1 at 26.) The list 24 does not include any certification in psychiatric mental health nursing. (Id.) 25 On August 3, 2021, Plaintiffs’ counsel sent another email to defense counsel, 26

27 14 Plaintiffs formally filed a separate Rule 56(d) motion requesting this relief. (Doc. 59). The Court denied the Rule 56(d) motion as moot because the request to 28 substitute Nurse Puchkors for Nurse Bala was “already properly before the Court via Plaintiffs’ other filings.” (Doc. 67 at 2.) 1 stating: “I asked a question about Nurse Markey’s qualifications. Can you get a cv for 2 her?” (Doc. 58-5 at 1.) 3 On September 14, 2021, Plaintiffs’ counsel again emailed defense counsel, stating: 4 “We have been trying for several months to get the deposition of Nurse Markey for some 5 time. I have a very open calendar (along with my partner). We have received zero response 6 to my email requests. Our expert disclosure is due on October 22[, 2021]. I need to depose 7 Nurse Markey several weeks before that deadline, so our expert can review the deposition.” 8 (Doc. 58-7 at 1.) 9 On September 17, 2021, Plaintiffs served their First Set of Requests for Production 10 of Documents on Defendant. (Doc. 58-8.) Among other things, Plaintiffs requested “[a] 11 current copy of Nurse Markey’s curriculum vitae, including a detailed listing of her 12 education, board certifications, and any other matters relevant to the qualifications of an 13 expert witness who might testify against Nurse Markey as listed in A.R.S. 12-2604.” (Id. 14 at 3-4.) 15 On October 12, 2021, Nurse Markey was deposed. (Doc. 58-9.) During the 16 deposition, defense counsel asked: “[D]o you have any additional certifications beyond 17 your degree?” (Id. at 2.) Nurse Markey responded: “Yes. I’m certified in psychiatric and 18 mental health through the [ANCC].” (Id. at 2-3.) Nurse Markey also testified about the 19 continuing education required to maintain her certification. (Id. at 3.) 20 On October 20, 2021, Defendant produced Nurse Markey’s resume. (Doc. 49 at 6; 21 Doc. 58-10 at 5.) 22 On October 22, 2021, Plaintiffs produced Nurse Bala’s report. (Doc. 49 at 6.) 23 In the Court’s view, this series of events demonstrates that Plaintiffs proposed their 24 initial expert, Nurse Bala, in good faith. Between May 2021 and October 2021, defense 25 counsel failed to respond to repeated requests from Plaintiffs’ counsel for more information 26 concerning Nurse Markey’s credentials.15 Given that the first notice Plaintiffs received

27 15 During oral argument, defense counsel sought to justify the failure to respond to Plaintiffs’ emails by characterizing them as informal discovery requests to which no 28 response was required. This is a disappointing and unpersuasive justification. Much time and effort could have been saved in this case had counsel simply responded to the emails 1 that Nurse Markey was board certified occurred in a deposition less than two weeks before 2 the October 22, 2021 deadline for expert disclosures (Doc. 49-1 at 12-13), and that 3 Plaintiffs did not receive Nurse Markey’s resume until two days before that deadline (Doc. 4 49 at 6), it is difficult to assign too much fault to Plaintiffs for failing to seek additional 5 time to secure a similarly qualified expert. 6 The timing of Defendant’s motion also weighs in favor of allowing substitution. 7 Defendant received Nurse Bala’s resume, which lists her “licenses and certifications” and 8 includes no mention of any certification related to psychiatric or mental health care, in June 9 2021. (Doc. 49-1 at 26; Doc. 58-6 at 1.) However, Defendant did not seek relief based on 10 the inadequacy of Nurse Bala’s certifications until July 2022. Although that request was 11 timely under the scheduling order, it was long after the deadline for Plaintiffs to identify a 12 new expert with the necessary credentials. Cf. Ellsworth, 2018 WL 1784687 at *4 13 (substitution may be justified where the expert’s qualifications were “plainly inadequate in 14 the affidavit” yet the moving party waited to challenge the proposed expert until a later 15 stage of the litigation).16 16 Accordingly, the Court grants Plaintiffs’ alternative request to nominate Nurse 17 Puchkors as their standard of care expert. The Court also grants Defendant’s alternative 18 request that “it be given an opportunity to depose the new expert . . . [and] have its expert 19 address the new expert’s opinions.” (Doc. 68 at 3 n.1.)17 20 … 21 … 22

23 in a professional manner. 16 Even if Defendant assumed that Nurse Bala held a certification in 2019 that was no 24 longer active by 2021, Nurse Bala’s certifications at the time of the challenged care are not material. Awsienko v. Cohen, 257 P.3d 175, 178 (Ariz. Ct. App. 2011) (“The language of 25 the statute does not require an expert testifying about the standard of care applicable to a board-certified defendant to have been board-certified at the time of the occurrence.”). 26 17 Because the Court grants Plaintiffs’ alternative request for substitution, the parties’ 27 arguments regarding Nurse Weishaar’s testimony need not be addressed. However, the Court notes that Nurse Weishaar, who the parties agree is not board certified in psychiatric 28 mental health nursing (Doc. 58 at 8), appears to lack the necessary qualifications under A.R.S. § 12-2604(A)(1) for the same reasons as Nurse Bala. 1 II. Summary Judgment 2 Defendant moves for summary judgment on two grounds. (Doc. 57.) First, 3 Defendant argues that Plaintiffs’ expert on the standard of care is not qualified under A.R.S. 4 § 12-2604(A)(1) and that, without a qualified expert, Plaintiffs cannot prove the requisite 5 standard of care. (Id. at 5-6.) Second, Defendant contends that Hager’s suicide was an 6 “intervening and superseding act that is the cause of Plaintiffs’ injuries” and thus relieves 7 Defendant from liability as a matter of law. (Id. at 7.) 8 Because the Court has granted Plaintiffs’ request to substitute Nurse Puchkors as 9 their standard of care expert, Defendant’s first summary judgment argument is denied 10 without prejudice. 11 Defendant’s second argument presents a closer question. In Arizona, the elements 12 of a medical malpractice action are provided by statute: 13 Both of the following shall be necessary elements of proof that injury resulted from the failure of a health care provider to follow the accepted 14 standard of care: 15 1. The health care provider failed to exercise that degree of care, skill and learning expected of a reasonable, prudent health care provider in 16 the profession or class to which he belongs within the state acting in the same or similar circumstances. 17 2. Such failure was a proximate cause of the injury. 18 19 A.R.S. § 12-563. “Regarding causation, a plaintiff must show ‘a natural and continuous 20 sequence of events stemming from the defendant’s act or omission, unbroken by any 21 efficient intervening cause, that produces an injury, in whole or in part, and without which 22 the injury would not have occurred.” Sampson v. Surgery Ctr. of Peoria, LLC, 491 P.3d 23 1115, 1118 (Ariz. 2021) (discussing proximate cause under § 12-563(2)). As for the 24 concept of intervening cause, the Arizona Supreme Court recently explained: 25 An intervening cause is an independent cause that occurs between a defendant’s negligent conduct and the final harm and is necessary in bringing 26 about that harm. It becomes a superseding cause, which relieves the original negligent actor from liability, when “an intervening act of another was 27 unforeseeable by a reasonable person in the position of the original actor and when, looking backward, after the event, the intervening act appears 28 extraordinary.” 1 Torres v. Jai Dining Services (Phoenix) Inc., 497 P.3d 481, 484 (Ariz. 2021) (internal 2 citations omitted). See also Rossell v. Volkswagen of Am., 709 P.2d 517, 525 (Ariz. 1985) 3 (“It is only when the intervening act is considered superseding cause that the original actor 4 is relieved of liability for his negligence.”). 5 Under Arizona law, the general rule is that “suicide by the injured party is a 6 superseding cause which is neither foreseeable nor a normal incident of the risk created 7 and therefore relieves the original actor from liability for the death resulting from the 8 suicide.” DeMontiney v. Desert Manor Convalescent Ctr. Inc., 695 P.2d 255, 259 (Ariz. 9 1985) (citation omitted). The so-called “suicide rule” thus short-circuits the proximate 10 cause analysis by presuming that suicide falls outside the realm of reasonable foreseeability 11 as a matter of law. However, Arizona recognizes two exceptions to this “general rule.”18 12 First, liability may exist “when the defendant negligently caused the decedent to 13 suffer delirium or insanity that either prevented him from realizing the nature of his act and 14 the certainty or risk of harm involved therein, or made it impossible for him to resist an 15 impulse caused by his insanity which deprived him of his capacity to govern his conduct 16 in accordance with reason.” Parton v. Jeans, 2019 WL 6608750, *2 (Ariz. Ct. App. 2019) 17 (cleaned up). Plaintiffs do not allege that Hager was suffering from delirium or insanity 18 caused by Defendant. (See generally Doc. 1.) Thus, the first exception is not at issue here. 19 Second, a “different rule” applies to actors that have “a specific duty of avoiding 20 suicide.” DeMontiney, 695 P.2d at 259. The Arizona Supreme Court has addressed this 21 exception in two decisions: Maricopa County v. Cowart, 471 P.2d 265, 267 (1970), and 22 DeMontiney. Cowart found a “[s]pecific duty of care to avoid suicide” for mental 23 institutions and applied that duty to juvenile homes. 471 P.2d at 267. DeMontiney 24 recognized a specific duty to avoid suicide by a health care facility providing custodial care 25 to a “mental hold” patient known to have suicidal tendencies. 695 P.2d at 259-60. See 26 18 A third exception may exist where the decedent falls within the protection of a 27 specific state statute. Crown v. Raymond, 764 P.2d 1146, 1147-49 (Ariz. App. Ct. 1988) (the general suicide rule did not apply to a gun shop owner who sold a weapon to a minor 28 because the injury was foreseeable given that a state statute prohibited the sale, expressing a legislative awareness that children in possession of guns may harm themselves). 1 also id. (“[I]t is the special relationship between two parties that can give rise to a duty to 2 prevent suicide. When an institution, such as Desert Manor, is charged with the care and 3 custody of persons who it knows will be likely to harm themselves, therefore, that special 4 relationship exists. Consequently, the institution has the duty to take reasonable steps to 5 prevent suicide.”). 6 Defendant contends the specific duty recognized in DeMontiney and Cowart is 7 limited to actors who had physical “custody” of the person who committed or attempted 8 suicide. (Doc. 57 at 8 & n.4 [arguing that because “Mr. Hager was not in the custody of 9 and had not been committed to the VA,” “[n]either the VA nor Nurse Markey owed Mr. 10 Hager a specific duty of care”].) In response, Plaintiffs argue that the VA owed a specific 11 duty of care to Hager, a military veteran seeking mental health treatment who was at risk 12 for suicide, based on its relationship with Hager as his medical provider. (Doc. 62 at 5-6 13 [“The Veterans Administration owes a duty to military veterans who need mental health 14 care and who may commit suicide.”].)19 15 The scope of the “specific duty” exception to the suicide rule is governed by Arizona 16 law. “When interpreting state law, a federal court is bound by the decision of the highest 17 state court.” In re Kirkland, 915 F.2d 1236, 1238 (9th Cir. 1990). “If the state’s highest 18 court has not decided an issue, it is the responsibility of the federal courts sitting in diversity 19 to predict how the state high court would resolve it.” Albano v. Shea Homes Ltd. P’ship, 20 634 F.3d 524, 530 (9th Cir. 2011) (citation and internal quotation marks omitted). “The 21 decisions of the state’s intermediate appellate courts are data that a federal court must 22 consider in undertaking this analysis.” Air-Sea Forwarders, Inc. v. Air Asia Co., 880 F.2d 23 176, 186 (9th Cir. 1989). 24 Whether the VA has a specific duty to protect mental health patients being seen on 25 an outpatient basis from suicide is a question the Arizona Supreme Court has not yet 26 19 The Court acknowledges that it is somewhat unclear whether Plaintiffs are arguing 27 that the VA clinic had a specific duty of care to take reasonable steps to prevent Hager’s suicide (in contrast to the general duty of reasonable care that may arise from a doctor- 28 patient relationship). (See Doc. 62 at 5-8.) The second exception to the suicide rule requires a “[s]pecific duty of care to avoid suicide.” Cowart, 471 P.2d at 267. 1 addressed. With that said, decisions from the Arizona Court of Appeals provide guidance 2 and largely support Defendant’s position that no specific duty arose here due to the absence 3 of a custodial relationship between the VA and Hager. See, e.g., Parton, 2019 WL 6608750 4 at *2-3 (applying the general rule to preclude a school’s liability for bullying that led to a 5 student’s suicide); Cohen v. Maricopa County, 263 P.3d 61, 62-65 (Ariz. Ct. App. 2011) 6 (affirming the dismissal of a medical malpractice claim against a county-licensed urgent 7 care center that provided “acute psychiatric services” on an outpatient basis, where a 8 patient committed suicide the day after a medical provider at the clinic denied an 9 application to hold the patient pursuant to a mental health detainer and allowed the patient 10 to return home, and explaining that one of the “important distinctions” between the case 11 and DeMontiney was that “the patient [in DeMontiney was] being involuntarily held in the 12 County’s custody,” and thus “the County ha[d] the ability to exclusively control the 13 environment surrounding the patient and to control and reduce risk associated with such 14 environment,” whereas the patient in the instant case was “out of such controlled 15 environment . . . [and thus] the County ha[d] little practical control over that patient, the 16 patient’s environment or the actions of others, and thus ha[d] little to no control over 17 risk”);20 Pompeneo v. Verde Valley Guidance Clinic Inc., 249 P.3d 1112, 1113 (Ariz. App. 18 Ct. 2011) (applying the general rule to preclude an outpatient psychiatric clinic’s liability 19 for a murder and subsequent suicide attempt);21 Tucson Rapid Transit Co. v. Tocci, 414

20 20 The extent to which Cohen was also based on the lack of a contractual relationship between the medical provider and the defendant county (rather than solely the absence of 21 physical custody) is unclear. See, e.g., 263 P.3d at 65 (describing the “the holding of DeMontiney as to non-delegable duty” of care as “limited to its unique setting” and 22 reasoning that “[i]f a county directly contracts with others to provide such care, it has the ability through contract to mandate how the care will be provided, and to control or manage 23 through an indemnity provision or an additional insured clause the risk of harm that might be caused by the negligence of such contracting provider”). 24 21 There are reasons to be cautious about reading Pompeneo as establishing a 25 bright-line rule against imposing a specific duty to avoid suicide on any outpatient treatment provider. Pompeneo involved an extreme series of events—the plaintiff was a 26 recovering addict who, after receiving treatment from the defendant outpatient clinic, murdered his girlfriend and then attempted suicide. 249 P.3d at 1113. He then filed a 27 medical malpractice action alleging, in relevant part, that he was entitled to damages for his unsuccessful suicide attempt. Id. at 1113-14. Moreover, Pompeneo’s analysis focused 28 on the first exception to the general rule—delirium or insanity caused by the defendant— and did not address the “specific duty” exception. 1 P.2d 179, 180-85 (Ariz. App. Ct. 1966) (applying the general rule to preclude a bus 2 company’s liability where the plaintiff attempted suicide following a bus accident that 3 allegedly caused her to suffer severe depression and noting “the practically unanimous rule 4 . . . that [suicide] is a new and independent agency which does not come within and 5 complete a line of causation from the wrongful act to the death and therefore does not 6 render defendant liable for the suicide”). 7 On the other hand, none of the relevant cases from the Arizona Court of Appeals 8 addressed the specific scenario at issue here—a VA clinic providing mental health 9 treatment to a patient population that is uniquely vulnerable to the risks of suicide. 10 Additionally, several recent decisions by Arizona courts (and courts applying Arizona law) 11 raise questions about whether the bright-line rule that Defendant asks the Court to apply 12 here (i.e., absent a custodial setting, suicide always constitutes a superseding cause that 13 precludes liability unless the defendant caused the decedent’s underlying mental condition) 14 remains the law in Arizona. For example, in Smith v. Chandler, 794 F. App’x 594 (9th 15 Cir. 2019), the plaintiff sued the city for injuries sustained when he attempted suicide 16 during an encounter with the city’s police officers. Id. at 595.22 The “district court . . . 17 held that, as a matter of Arizona law, Appellant’s suicide attempt superseded the City’s 18 alleged negligence as the cause of Appellant’s injuries because Officer Smith did not cause 19 Appellant’s underlying mental condition” but the Ninth Circuit reversed, holding that the 20 district court “failed to analyze Appellant’s claim under applicable Arizona tort law 21 relating to applicable duty and foreseeability concepts. Under Arizona law, whether an 22 event . . . constitutes a superseding cause is ordinarily a question of fact for the jury to 23 decide.” Id. at 595-96 (citations omitted). Admittedly, Smith is an unpublished decision 24 and is factually distinguishable from this case, but it nonetheless provides some indication 25 that Arizona law on this issue does not establish as strict a rule as Defendant contends (and 26 22 Specifically, the suicide attempt occurred in the presence of law enforcement 27 officers while the plaintiff was physically surrounded by officers (one of whom deployed several beanbag rounds at him). Smith v. City of Chandler, 2014 WL 1493004, *2 (D. 28 Ariz. 2014). It does not appear the plaintiff was formally in the custody of the officers at the time of the suicide attempt. 1 that a finding of liability may be possible even absent a custodial relationship). 2 Similarly, in Delgadillo v. BNSF Ry. Co., 2022 WL 4305625 (D. Ariz. 2022), the 3 decedent committed suicide by laying in front of an oncoming train. Id. at *1. In the 4 ensuing wrongful death action brought by the decedent’s sister, the railroad sought 5 summary judgment under Cowart, arguing that “Decedent was committing suicide, thus 6 severing the causal chain and barring liability.” Id. at *2. The district court disagreed and 7 denied the summary judgment motion, holding that “it’s not surprising or unpredictable 8 that a motionless object will block ground-level tracks.” Id. Although Delgadillo (like 9 Smith) is not binding here, involved dissimilar facts, and did not specifically address 10 whether the duty/causation analysis turned on the presence or absence of physical custody, 11 it is another example of a recent decision that casts some doubt on Defendant’s position. 12 Separately, and perhaps more important, the Arizona Court of Appeals recently 13 questioned the wisdom of the common-law suicide rule and invited the Arizona Supreme 14 Court to revisit it: 15 [W]e believe our supreme court should revisit the aging majority rule. The majority rule draws from society’s historical view of suicide as sinful and 16 immoral, and its historical classification as a felony. But societal and legal views of suicide have evolved—our understanding of mental health has 17 changed, moral perspectives on suicide are more diverse, and the classification of suicide as a crime has long been discarded. The majority 18 rule fails to consider those changes. Further, it fails to account for modern legislative willingness to recognize that wrongful conduct which may 19 increase the risk of suicide . . . should be addressed by the law. . . . [T]he majority rule effectively short-circuits any real analysis into whether the 20 decedent’s suicide was within the scope of foreseeable risk created by the defendant’s negligence. The majority rule therefore may produce anomalous 21 results, precluding relief for suicide when it is the precise harm that a reasonable person could foresee. . . . Accordingly, some courts are beginning 22 to move beyond rote application of the suicide rule and its exceptions and toward a more traditional scope-of-risk analysis, recognizing that the 23 traditional analysis is sufficient to address the vast majority of these cases without relying upon the fiction that suicide is a superseding cause as a matter 24 of law. We believe that these courts have taken the correct approach, but we cannot follow the modern approach until and unless our supreme court 25 changes Arizona law. 26 Parton, 2019 WL 6608750 at *2-3 (internal citations and quotation marks omitted). 27 Although the Arizona Supreme Court did not accept this invitation—in November 2020, it 28 denied the petition for review in Parton—the Court does not view this outcome as a 1 conclusive determination that the Arizona Supreme Court would also reject the position 2 that Plaintiffs advance here. For one thing, the facts of this case differ from the facts of 3 Parton and, arguably, present a more compelling vehicle for revisiting the wisdom of the 4 “aging majority rule.” In the Court’s estimation, a VA clinic providing mental health 5 treatment to veterans suffering from PTSD and other mental health maladies qualifies as 6 an almost quintessential example of a setting where the risk of suicide is foreseeable. 7 Additionally, since it denied the petition for review in Parton, the Arizona Supreme 8 Court issued another ruling that touches upon what it means for a cause to be superseding 9 under Arizona law. Torres, a dram-shop liability case, raised the question whether a club 10 could be liable for a car accident that occurred when an intoxicated patron left the club, 11 drove home, took a short nap, and then, while driving a friend home later that night, still 12 intoxicated, hit and killed two third parties. 497 P.3d at 482-83. The Arizona Court of 13 Appeals held that the club could not be liable as a matter of law because once the driver 14 “had ‘safely reached his residence, gone to bed, and fallen asleep, with no known 15 compelling reason to leave,’ his independent decision to leave and drive his truck was an 16 intervening and superseding cause that broke the chain of proximate causation.” Id. at 483 17 (citation omitted). The Arizona Supreme Court reversed, holding that whether the decision 18 by the intoxicated patron to resume driving after reaching home was a superseding cause 19 as a matter of law depended on “the scope of risk in dram shop cases.” Id. at 484. 20 Specifically, the Court held that if an intervening cause falls within the scope of the original 21 risk created by the negligent conduct (i.e., the foreseeable risk), it is not a superseding 22 cause. Id. at 484-85. Torres suggests that Arizona law in this area may be in flux, and its 23 focus on foreseeability potentially weighs against maintaining a bright-line rule barring 24 liability for injuries caused by suicide (or suicide attempts) against outpatient healthcare 25 providers treating patients at risk for suicidal behavior.23 26 Against this backdrop, the Court is reluctant to find, as a matter of Arizona law, that 27

28 23 On the other hand, Torres could also be interpreted as a narrow decision that only affects the rules in dram-shop cases. 1 the VA has no specific duty to protect a veteran seeking mental health treatment from 2 suicide simply because the treatment is being provided on an outpatient basis (particularly 3 where, as here, the veteran had a history of suicidal ideation).24 The VA provides mental 4 health care to a population that is particularly vulnerable to the risk of suicide.25 Given the 5 importance of this issue and the presence of nonfrivolous reasons to believe the law may 6 not be as settled as Defendant portrays it to be, and with recognition that it should be the 7 Arizona courts (not federal courts applying Arizona law) who resolve weighty and 8 potentially unsettled state-law issues, the Court would be inclined to certify the question to 9 the Arizona Supreme Court. “Through certification of novel or unsettled questions of state 10 law for authoritative answers by a State’s highest court, a federal court may save time, 11 energy, and resources and hel[p] build a cooperative judicial federalism.” Arizonans for 12 Off. Eng. v. Arizona, 520 U.S. 43, 77 (1997) (citations and internal quotation marks 13 omitted). See also Benson v. Casa de Capri Enterprises, LLC, 980 F.3d 1328, 1332 (9th 14 Cir. 2020) (“In the absence of any apparent controlling precedent, and out of respect for 15 Arizona courts and their preeminent role in interpreting Arizona law, we believe it most 16 suitable to certify this issue to the highest court of the state whose law is in question.”) 17 (citation and internal quotation marks omitted). 18 The Court also concludes, however, that it would be premature to make a 19 certification request at this time. The Arizona Supreme Court may accept a request for 20 certification only if the question to be resolved “may be determinative of the cause then 21 pending in the certifying court and as to which it appears to the certifying court there is no 22 controlling precedent in the decisions of the supreme court and the intermediate appellate 23 courts of this state.” A.R.S. § 12-1861. The latter part of this test seems satisfied here

24 24 To be clear, the Court does not find that the Nurse Markey acted negligently or that Hager’s suicide was a foreseeable risk of such negligence. Instead, the Court questions 25 whether the mere fact that Willow Clinic is an outpatient facility bars (or should bar) any potential for liability as a matter of law. 26 25 See, e.g., Mark S. Kaplan, Suicide Risk and Precipitating Circumstances Among 27 Young, Middle-Aged, and Older Male Veterans, 102 AM. J. PUB. HEALTH S131, S133 (2012) (“The risk of suicide among male veterans compared with nonveterans was 28 statistically significantly greater in all age groups, except for those aged 65 years and older.”), available at https://pubmed.ncbi.nlm.nih.gov/22390587/. 1 because, as discussed above, the specific duty issue is a “novel or unsettled question[] of 2 state law” as to which “there is no controlling precedent” from the Arizona courts. 3 Arizonans for Off. Eng., 520 U.S. at 77; A.R.S. § 12-1861. But as for the former part of 4 the test, it is not yet clear whether the disputed issue of law is determinative of Plaintiffs’ 5 claims. Defendant contends it is entitled to summary judgment even under “a standard 6 duty and causation analysis” because Plaintiffs have provided insufficient evidence that 7 Nurse Markey was negligent and that such negligence caused Hager’s suicide. (Doc. 68 at 8 8-11.) Additionally, as discussed in Part I above, the Court has now authorized Plaintiffs 9 to designate a new expert, Nurse Puchkors, on these topics and to reopen discovery to allow 10 Defendant to depose Nurse Puchkors. Depending on how that process goes, Defendant 11 may have additional grounds for seeking summary judgment that are not dependent on the 12 resolution of the legal question the Court would otherwise be inclined to certify. Under 13 these circumstances, it makes sense to wait for those processes to play out before making 14 any certification request.26 15 … 16 … 17 … 18 … 19 … 20 … 21 … 22 … 23 … 24

25 26 The Court further notes that, if it were to make a certification request at the conclusion of those processes but the Arizona Supreme Court were to deny the certification 26 request, it would proceed to make its best “Erie guess” on the disputed issue of Arizona law and then resolve Defendant’s renewed summary judgment motion on the basis of that 27 determination. Thornell v. Seattle Service Bureau, Inc., 742 F. App’x 189, 190-91 (9th Cir. 2018) (where the Washington Supreme Court declined to grant a certification request 28 as to a particular issue, “we must engage in an ‘Erie guess’ as to how that court would resolve [that] issue”). 1 Accordingly, 2 IT IS ORDERED that: 3 (1) Defendant’s motion to disqualify Nurse Bala as Plaintiffs’ standard of care 4|| expert (Doc. 49) is granted. 5 (2) Plaintiffs’ request to substitute Nurse Puchkors as their standard of care || expert (Doc. 58) is granted. 7 (3) Defendant’s corresponding request to reopen discovery (Doc. 68) is granted. 8 (4) Defendant’s motion for summary judgment (Doc. 57) is denied without 9|| prejudice. 10 (5) □ The parties shall meet and confer about a schedule for completing the 11 |} reopened discovery process and allowing Defendant to file a successive motion for summary judgment.
