OPINION
¶ 1 Appellant appeals from the superior court’s May 1, 2006 order compelling her to undergo involuntary inpatient and outpatient mental health treatment. The order was issued following a hearing at which Appellant was not present. We hold that although a patient has the power to waive attendance at an involuntary treatment hearing, the patient’s waiver is ineffective unless the superi- or court expressly finds that it is given knowingly and intelligently. Because we hold the evidence did not support the superior court’s conclusion that Appellant knowingly and intelligently waived her right to be present, we remand for a new hearing on that issue.
FACTUAL AND PROCEDURAL HISTORY
¶ 2 On April 17, 2006, a medical doctor and a clinical liaison petitioned the superior court for an involuntary mental health evaluation of Appellant. An application for involuntary evaluation and a pre-petition screening report accompanied the petition. The petition stated that there was reasonable cause to believe that Appellant was persistently or acutely disabled. According to the petition, Appellant demonstrated “poor judgment and insight,” had “become extremely paranoid,” was experiencing “auditory and visual hallucinations,” and was psychotic. The petition stated that Appellant would not take her prescription medication because she thought it had been tampered with, would not eat because she believed the group home staff was putting chemicals in her food, believed she was being raped on a daily basis at her group home and wandered away from her group home. On April 18, 2006, the superior court issued a detention order for the evaluation of Appellant.
¶ 8 On April 24, 2006, after Appellant had been evaluated, another medical doctor filed a petition asking that Appellant be compelled to undergo treatment. The physician asserted that Appellant was persistently or acutely disabled and concluded that Appellant needed “further inpatient evaluation and stabilization of her psychotic illness.” According to the physician’s affidavit, Appellant had been diagnosed with schizoaffective disorder. During an interview, she told the physician she was being drugged, her medication was being poisoned, chemicals had been sprayed on her blankets, and people were coming into her group home and raping her. The physician described Appellant’s thought process as “significant for paranoid thinking and delusions,” and concluded that her concentration, insight and judgment were impaired. She stated that Appellant had “limited capacity to recognize reality secondary to her psychosis” and that her mental disorder limited her capacity to make an informed decision regarding treatment. She lacked insight into her mental illness, the physician said, and because she was refusing to take her medications, her psychosis was worsening.
¶4 An affidavit of yet a third physician also noted that Appellant believed her medication and food were being poisoned. Although Appellant reported experiencing visual and auditory hallucinations, she denied having been diagnosed with a mental illness. “The patient demonstrates extremely poor insight,” the third doctor wrote. “The patient’s judgment is also impaired.” He concluded that Appellant was suffering from “an acute decompensation of a chronic psychotic disorder.” He stated that Appellant was “suffering from paranoid delusionality and auditory and visual hallucinations,” and was refusing medication and treatment. Like the second physician, he concluded that Appellant’s mental disorder “substantially im-pahfed]” her capacity to make an informed decision regarding treatment.
¶ 5 In response to the petition, the court issued a “Detention Order for Treatment and Notice” on April 25, 2006 that set a hearing pursuant to Arizona Revised Statutes (“A.R.S.”) section 36-539 (2003) for May 1, 2006, at 10:30 a.m. Pursuant to the April 25 order, Appellant was detained in an annex to the Maricopa Medical Center pending the hearing on the petition for court-ordered
¶ 6 On its own motion, the trial court called the court’s transportation officer to testify about Appellant’s absence. (The transportation officer delivers patients from the annex to court for hearings.) The transportation officer testified that he had spoken with Appellant in person at 7:45 a.m. the morning of the hearing. He testified that he asked Appellant if she knew “she was to attend court” that day, and that Appellant responded that she did know and that she would be attending. When the transportation officer returned just after 9:00 a.m. to take Appellant to court, Appellant started to walk with him but then asked him where they were going. He answered that they were going to court. According to the transportation officer, Appellant then stated: “Well, that’s okay. But I can’t go with you because I don’t know you.” The officer explained that he was the transportation officer, but Appellant again stated she could not go with him because she did not know him.
¶ 7 At that point, the officer asked Appellant if she had spoken to her public defender, and Appellant answered that she had not spoken to her public defender, any lawyers or any doctors. The officer then told Appellant she did not have to go to court if she did not want to, but that he was the person who would take her if she wanted to go. Appellant again said that she could not go with him because she did not know him.
¶ 8 Appellant’s counsel argued that given the pending allegations about Appellant’s mental condition, the court could not assume Appellant had voluntarily waived her right to be at the hearing. The court disagreed, and found Appellant had voluntarily waived her presence: “The real issue is under [A.R.S. § 36-539(B)] as the language of the statute says the patient ... shall be present. This Court has taken the ... position that I will not force a person to come and aggravate any potentially already fragile situation____I will find that [Appellant] has voluntarily waived her appearance here.” Over the objection of Appellant’s counsel, the court then ordered that the hearing “proceed in absen-tia.”
¶ 9 At the hearing, Appellant’s counsel and counsel for the county agreed to submit the physicians’ affidavits in lieu of their testimony. The court heard live testimony of two witnesses, a behavioral health agency case manager and a worker at Appellant’s group home.
¶ 10 The case manager testified that Appellant had called her one morning to pick Appellant up from a bus stop where Appellant had spent the night. When the case manager picked Appellant up, Appellant said she had not taken her medication and that she had urinated on herself. The case manager testified that while at Appellant’s residence, Appellant repeatedly asked her, “Can you smell that?” but the case manager could smell nothing. While at Appellant’s residence, she told the ease manager that a picture frame was emitting poisonous chemicals. The case manager took Appellant to a clinic to be assessed by her psychiatrist, where she observed Appellant smelling her pill box before she took her medication. The case manager also testified that Appellant had told her that she had broken her radio because “they kept calling her name [on] the radio.”
¶ 11 The worker from Appellant’s group home testified that Appellant believed her food was being poisoned and that other residents were trying to rape and kill her. The worker stated that she recently heard Appellant tell her caseworker she had not taken her medication for four days. She testified that the next evening, Appellant was screaming the 23rd Psalm while repeatedly slamming the refrigerator door shut, saying, “They’re not going to kill me, they’re not going to take me.” The worker testified that when Appellant was asked whom she was talking to, Appellant replied, “Can’t you see that I’m having a conversation and you’re not
¶ 12 After considering the evidence, the court found that Appellant was persistently or acutely disabled and ordered Appellant to be involuntarily treated in a combined inpa-tienVoutpatient program for a period not to exceed 365 days. Appellant timely appealed the order. We have jurisdiction pursuant to A.R.S. §§ 12-120.2KA) (2003) and 36-546.01 (2003).
DISCUSSION
¶ 13 We review de novo the interpretation and application of a statute because they are questions of law. See In re Maricopa County No. MH 2001-001139,
¶ 14 Involuntary treatment by court order is “a serious deprivation of liberty.” In re Coconino County No. MH 1425,
¶ 15 The procedural requirements the legislature established to implement a patient’s due-process rights in an involuntary treatment hearing in this state are set forth in A.R.S. § 36-539. Among other requirements, the statute provides that “[t]he patient and his attorney shall be present at all hearings____’’A.R.S. § 36-539(B).
¶ 16 Appellant argues that the statute’s mandate that the patient “shall be present” requires that an involuntary treatment hearing may not take place without the presence of the patient, and that the superior court’s decision in this case to go forward in her absence therefore violated her statutory right to due process. See Coconino County No. MH 1425,
¶ 17 “If the language of a statute is clear and unambiguous, the court will apply the plain meaning of the language unless a plain
¶ 18 The intended beneficiary of a statute generally may waive the statute’s benefit. See Holmes v. Graves,
¶ 19 Our conclusion that section 36-539 does not foreclose a patient from waiving her appearance at an involuntary treatment hearing is buttressed by the fact that a contrary reading of the statute would lead to an absurd result. If the statute were interpreted to prohibit a patient from waiving the right to be present, a patient could avoid entry of an involuntary treatment order against her simply by refusing to attend the hearing, thereby stopping the statutory procedure in its tracks. We decline to countenance such an illogical result.
¶20 That Appellant had the power to waive her statutory right to attend the hearing does not dispose of the matter, however. The general rule is that a waiver is not effective unless it is given voluntarily and intentionally. Nahom v. Blue Cross & Blue Shield of Ariz.,
¶ 21 In State v. Thompson,
¶ 22 The court in Evans affirmed the superior court’s decision to permit a defendant diagnosed as a paranoid schizophrenic to waive counsel.
¶23 These cases demonstrate that some mentally ill persons have the capacity to knowingly and intelligently waive a fundamental right. But not every mentally ill person may do so; it goes without saying, for example, that a person who is so mentally disordered as to be incompetent cannot knowingly or intelligently decide to waive such a right. Id. at 402,
¶ 24 A petition seeking court-ordered treatment necessarily alleges that the patient, “as a result of mental disorder, is a danger to self or to others, is persistently or acutely disabled or is gravely disabled” and “is unwilling to accept or incapable of accepting treatment voluntarily.” A.R.S. § 36-533(A) (2003). Given that the purpose of an involuntary treatment proceeding is to assess allegations that a person suffers from a serious mental disorder that so significantly affects her that she is unwilling or incapable of accepting treatment, the superior court may not presume that a patient who is absent from her involuntary treatment hearing has knowingly and intelligently waived her right to be present.
¶ 25 Cases from other jurisdictions, along with Evans and Thompson, caution that the superior court must scrutinize careftilly any contention that a mentally impaired person has waived a right such as that at issue here. In Honor v. Yamuchi,
¶ 26 In In re Click,
¶ 27 The superior court commissioner in this case stated he was reluctant to “force” a patient to appear at an involuntary treatment hearing because of a concern about “aggravating] any potentially already fragile situation” with the patient. We appreciate the court’s legitimate concern about the possible effect the proceeding might have on a patient’s mental state, and as stated above, we agree that notwithstanding section 36-539(B), a patient may waive her right to be present at a hearing called under that provision. We hold, however, that a patient’s purported waiver of her right to be present at a hearing called pursuant to section 36-539 is not valid absent an express finding by the court that the patient has knowingly and intelligently waived her right to be present.
¶28 “The finding of voluntary absence, and, therefore, the existence of a waiver of the right to be present, is basically a question of fact.” State v. Bishop,
¶ 29 The better practice in cases in which a court is called upon to assess whether a right has been voluntarily waived is to make specific findings. Evans,
¶30 Although we are bound not to upset the superior court’s finding of a voluntary waiver absent an abuse of discretion, see Bishop,
¶ 31 A.R.S. § 36-536(A) (2003) required that Appellant be personally served with notice of the hearing, but there is no evidence in the record that Appellant understood the nature of the proceeding or that she understood the significance of her failure to attend it.
¶ 32 The only facts before the court that specifically related to Appellant’s failure to appear at the hearing were those offered by the transportation officer, who testified that she told him that she would not accompany him to court because he was a stranger to her. Although Appellant acknowledged an awareness of some court proceeding and appeared to indicate a desire to attend, there was no evidence that she comprehended the nature of the involuntary treatment hearing or of her right to attend that hearing. Indeed, in response to the transportation officer’s question, Appellant denied having spoken to any lawyer or any doctor.
¶33 Given the absence of any evidence that Appellant knowingly chose not to appear at her involuntary treatment hearing, and the wealth of evidence that her mental disorder significantly impaired her ability to know and assess reality, we hold that the superior court’s ruling that Appellant voluntarily waived her right to appear at the hearing was not supported by substantial evidence. Because there was insufficient evidence to find Appellant had voluntarily waived her right to appear at the hearing, the hearing should not have gone forward in her absence.
CONCLUSION
¶ 34 For the foregoing reasons we remand this matter to allow the superior court to conduct a prompt hearing to determine whether Appellant knowingly and intelligently waived her right to be present at the involuntary treatment hearing. If the court
Notes
. Neither side contended that Appellant was absent pursuant to A.R.S. § 36-539(C), which permits an involuntary treatment hearing to go forward when medical reasons prevent the patient from being present.
. Appellant did not move to accelerate this appeal pursuant to Arizona Rule of Civil Appellate Procedure 29. Accordingly, the appeal was briefed and set for conference in the ordinary course.
. “The loss of liberty produced by an involuntary commitment is more than a loss of freedom from confinement. It is indisputable that commitment to a mental hospital ‘can engender adverse social consequences to the individual’ and that '[w]hether we label this phenomena "stigma” or choose to call it something else ... we recognize that it can occur and that it can have a very significant impact on the individual.' ” Vitek,
. Section 36-539 also provides that "the patient’s attorney may subpoena and cross-examine witnesses and present evidence,” that a verbatim record of all proceedings shall be kept and that the Arizona Rules of Civil Procedure shall apply to such hearings (unless inconsistent with the statute). A.R.S. § 36-539(B), (D).
. See also Pate v. Robinson,
. We do not mean to say that a patient who is unable to give a valid waiver but who becomes unduly agitated by the courtroom proceedings must be compelled, by restraints or otherwise, to remain in the courtroom. See Suzuki,
. This case does not require us to decide whether, in the absence of a valid waiver by the patient, the court may accept a waiver offered on behalf of the patient by counsel or guardian ad litem. See French v. Blackburn,
. Because of our remand, we do not reach Appellant’s contention on appeal that she failed to receive the personal notice that section 36-536(A) requires.
