Background
After R.L. refused mental health evaluation and treatment at a medical facility, a psychiatric mental health nurse practitioner petitioned for a court-ordered evaluation. R.L. was detained and transferred to a hospital, where two evaluating physicians later supported a petition for court-ordered treatment. Their affidavits described delusional statements and diagnosed R.L. with bipolar I disorder with psychosis and schizoaffective disorder, respectively.
At the treatment hearing, the parties stipulated to the physicians’ affidavits, and a licensed social worker and registered nurse testified. The social worker described two pre-petition encounters in which R.L. questioned whether she was pregnant, rejected an assurance that she was not, became angry and yelled, and approached the social worker. Finding clear and convincing evidence that R.L. was persistently or acutely disabled by a mental disorder and unwilling or unable to accept voluntary treatment, the superior court ordered inpatient and outpatient treatment for no more than 365 days, with inpatient treatment capped at 180 days.
The Court’s Holding
The Court of Appeals held that the social worker was eligible to testify under A.R.S. § 36-539(B). As amended in 2025, the statute permits testimony from witnesses who “observed or were acquainted with” the patient at the relevant time. Because those alternatives are disjunctive, the social worker did not need to satisfy the separate requirement of being acquainted with R.L.
The social worker personally observed R.L. before the treatment petition, and her testimony was confined to observed facts rather than expert opinions or conclusions. The statute imposes no minimum observation period or requirement that observations occur in informal, day-to-day settings. The court also concluded that her testimony was distinct from the physicians’ medical diagnoses and expert opinions. It therefore affirmed the treatment order.
Key Takeaways
- Under the current version of A.R.S. § 36-539(B), a witness may qualify by having observed the patient even if the witness was not acquainted with the patient.
- The statute requires testimony limited to observed facts and does not prescribe a minimum duration or particular setting for the observation.
- The social worker’s brief pre-petition encounters supplied a permissible factual perspective distinct from the evaluating physicians’ expert testimony.
Why It Matters
The decision applies the statute’s 2025 amendment according to its plain language and explains that older cases focused on “acquaintance witnesses” offer limited guidance when a witness qualifies through observation instead. Challenges based solely on insufficient familiarity will not disqualify a witness who personally observed the patient and stays within the statute’s limits.
The memorandum decision is not precedential under Arizona Supreme Court Rule 111(c) and may be cited only as that rule permits.
