JUSTICE MONTGOMERY authored the Opinion of the Court, in which CHIEF JUSTICE TIMMER, VICE CHIEF JUSTICE LOPEZ and JUSTICES BOLICK, BEENE, KING, and BERCH (Retired) joined. *

JUSTICE MONTGOMERY, Opinion of the Court:

¶1 Arizona law establishes a multi-step process for the involuntary treatment of a mental disability. Preliminary to a court-ordered evaluation for mental health treatment, “[a]ny responsible individual may apply for a court-ordered evaluation of a person who” meets specified criteria involving a mental disability and “is unwilling or unable to undergo a voluntary evaluation.” See A.R.S. § 36-520(A) (2022). 1 Then, a licensed healthcare agency conducts a screening evaluation of the person. See A.R.S. § 36-521(A). If the screening establishes reasonable cause to believe that the person has a mental disability and will not voluntarily undergo an evaluation, the healthcare agency must prepare and file a petition for a court-ordered evaluation. See A.R.S. § 36-521(D).

¶2 If, after reviewing the petition, the superior court finds reasonable cause to believe that the statutory criteria are met, the court must order an evaluation. See A.R.S. § 36-529(B). If the evaluating agency determines that the person—now designated as the patient—has a serious mental health disability, the agency must petition the court for an order for treatment. See A.R.S. § 36-531(B).

¶3 At the hearing on the petition for court-ordered treatment (“COT”), the petitioner must provide “the testimony of two or more witnesses . . . acquainted with the patient at the time of the alleged mental disorder” (“acquaintance witnesses”), as well as testimony from two physicians or healthcare professionals who evaluated the patient. See A.R.S. § 36-539(B). If the court finds clear and convincing evidence of the

* Justice Maria Elena Cruz is recused from this matter. Pursuant to article 6, section 3 of the Arizona Constitution, Justice Rebecca White Berch (Retired) of the Arizona Supreme Court was designated to sit in this matter. 1 Because the statutes in question were significantly amended by the Legislature in 2025, we cite to the versions in effect at the time of this case. We note as appropriate where amendments affect our analysis.

need for treatment, it may order inpatient, outpatient, or combined care. See A.R.S. § 36-540(A), (D).

¶4 In this case, a licensed social worker, M.G., assessed A.R. to gather information for the purpose of determining an appropriate level of care, including whether to petition for a court-ordered evaluation. Later, at a hearing on a COT petition for A.R., M.G. testified as an acquaintance witness. Two issues arise from these circumstances. First is whether M.G., given her status as a licensed social worker and role in the screening process, could testify as an acquaintance witness under § 36-539(B) at A.R.’s COT petition hearing. Second is whether M.G. and A.R. had a confidential “behavioral health professional-client relationship” under A.R.S. § 32-3283(A), which would preclude M.G. from testifying about any information received from A.R.

¶5 With respect to the first issue, on March 31, 2025, the Legislature amended § 36-539(B) to clarify that licensed behavioral health professionals may testify as acquaintance witnesses under the circumstances presented here. 2 Moreover, during the pendency of the

2 Section 36-539(B) now provides:

The patient and the patient’s attorney shall be present at all hearings, and the patient’s attorney may subpoena and cross-examine witnesses and present evidence. The patient may choose to not attend the hearing or the patient’s attorney may waive the patient’s presence. The evidence presented by the petitioner or the patient shall include the testimony of two or more witnesses, regardless of the witnesses’ professional licensure, if any, who observed or were acquainted with the patient at the time of the alleged mental disorder before the submission of the current application for evaluation pursuant to [section] 36-520 or, if after the submission of the current application, who were not formal participants in the evaluation process. The testimony of the witnesses shall be limited to observed facts and may not include expert opinion or conclusions.

2025 Ariz. Sess. Laws ch. 20 § 1 (1st Reg. Sess.) (emphasis added).

3 IN RE: MH2023-004502 Opinion of the Court

appeal, the court’s treatment order for A.R. expired. For these reasons, we decline to address this issue as it is moot. As for the second issue, we hold that because A.R. and M.G. did not have a behavioral health professional-client relationship under § 32-3283(A), the related privilege and confidentiality requirements do not apply to preclude M.G. from testifying.

I. FACTUAL AND PROCEDURAL BACKGROUND

¶6 A.R. has a history of mental illness. After A.R.’s mother found him confused and unresponsive at home in May of 2023, she brought him to the hospital. M.G. assessed A.R. to provide “level of care” recommendations. Before the assessment, M.G. introduced herself to A.R. as a “crisis interventionist.” M.G. further informed A.R. that their conversation was subject to disclosure because it could result in a petition for court-ordered evaluation, and ultimately a petition for COT.

¶7 Based on information from the assessment, M.G. applied for an involuntary evaluation under § 36-520 and for an emergency admission for evaluation under A.R.S. §
