delivered the opinion of the court:
The trial court found respondent to be subject to involuntary admission to a mental health facility and placed him in the custody of the Department of Human Services. The appellate court affirmed, holding that, under the Mental Health and Developmental Disabilities Code (Code) (405 ILCS 5/1 — 100 et seq. (West 2000)), an individual may be subject to involuntary commitment to a state mental health facility even though he had initially committed himself voluntarily to a private hospital and had not requested in writing a discharge. No. 5 — 00— 0607 (unpublished order under Supreme Court Rule 23). We granted respondent’s petition for leave to appeal (177 Ill. 2d R. 315) and now affirm.
BACKGROUND
On September 5, 2000, respondent, a 20-year-old male, was admitted as a voluntary patient to the inpatient psychiatric unit of St. Clare’s Hospital (St. Clare’s), a private hospital in Alton, Illinois. Respondent was diagnosed with sub stance-induced psychotic disorder. This was respondent’s first hospitalization related to mental health services.
On September 8, 2000, respondent was transported to Alton Mental Health Center (Alton) after staff at St. Clare’s executed a petition for involuntary admission by emergency certificate pursuant to section 3 — 600 of the Code (405 ILCS 5/3 — 600 (West 2000)). On September 11, 2000, the State filed a “Petition for Involuntary/ Judicial Admission” (petition) seeking to admit respondent involuntarily. A second petition was filed the following day. In the second petition, it was alleged that respondent was mentally ill, that because of his mental illness he was reasonably expected to inflict serious physical harm upon himself or another in the near future, and that he was in need of immediate hospitalization to prevent such harm. The second petition stated that respondent had been suspicious, paranoid, and delusional and claimed to have been hearing the “Devil’s voice.” A knife, which he was going to use to “protect himself from his parents,” had apparently been taken away from him. Respondent refused to eat or take his medication. The second petition also referred to a recent incident at a nearby college where respondent struck another student because he thought the student was a threat to him.
The second petition was accompanied by a certificate from a qualified mental health examiner, as required by section 3 — 602 of the Code (405 ILCS 5/3 — 602 (West 2000)), in which the examiner indicated that he had examined respondent on September 8, at St. Clare’s, and had determined that respondent was mentally ill. The examiner concluded that because of his mental illness he was unable to provide for his basic needs so as to guard himself from serious harm. The examiner found that respondent exhibited signs of acute psychosis. He had paranoid delusions that his parents were going to kill him and was very preoccupied with religion, believing that he was fighting with the devil. Respondent refused to comply with his treatment or medication and was a threat to his parents.
A hearing on the State’s petition was held on September 14, 2000. Respondent’s attorney stated that respondent was discharged from St. Clare’s because “he didn’t want to take medication and because he would not have insurance coverage.” Dr. Jim Belman, a licensed clinical psychologist at Alton, testified for the State. Dr. Belman testified that respondent had been diagnosed with substance-induced psychotic disorder. He reiterated the basic facts supporting the allegations contained in the second petition and accompanying certificate, including that respondent heard the voices of Satan and God talking in his head, refused medication, and refused to eat. Dr. Belman also testified regarding continuing problems respondent was experiencing since being moved to Alton.
Prior to the hearing, respondent filed a “Motion to Strike and Dismiss” the petition, arguing that the petition for involuntary admission was improper because it had not been preceded by respondent’s making a written request for discharge pursuant to case law under section 3 — 403. After hearing the evidence, the trial court denied respondent’s motion and found respondent to be a person subject to involuntary admission. The appellate court affirmed and rejected respondent’s argument that he could not be involuntarily admitted because he did not request in writing to be discharged from St. Clare’s.
ANALYSIS
The question presented in this appeal is one of law, which we review de novo. Woods v. Cole, 181 Ill. 2d 512, 516 (1998). We are asked to determine whether a hospital not owned and operated by the State of Illinois can initiate a petition for involuntary commitment against one of its voluntary mental health patients, who has not requested a discharge in writing, to facilitate transferring the patient to a state facility. This issue requires an examination of section 3 — 403 of the Code, which provides:
“A voluntary recipient shall be allowed to be discharged from the facility at the earliest appropriate time, not to exceed 5 business days, excluding Saturdays, Sundays and holidays, after he gives any treatment staff person written notice of his desire to be discharged unless he either withdraws the notice in writing or unless within the 5 day period a petition and 2 certificates conforming to the requirements of paragraph (b) of Section 3 — 601 and Section 3 — 602 are filed with the court. Upon receipt of the petition, the court shall order a hearing to be held within 5 days, excluding Saturdays, Sundays and holidays, and to be conducted pursuant to Article IX of this Chapter. Hospitalization of the recipient may continue pending further order of the court.” 405ILCS 5/3 — 403 (West 2000). We have had prior occasions to review section 3 — 403.
In In re Hays, 102 Ill. 2d 314 (1984), the 19-year-old respondent voluntarily admitted himself to the psychiatric unit of Mercy Hospital in Urbana. He had been voluntarily admitted there on nine previous occasions over the previous four years. On the day following his admission, he refused to take medication, threw a phone at security guards, and became physically resistive. After being physically restrained, he told a nurse that he wanted to die. He was given medication and did not cause any further disturbance. The hospital petitioned the trial court to have the respondent declared a person subject to involuntary admission under the Code (Ill. Rev. Stat. 1981, ch. 911/2, par. 3 — 600 et seq.). The purpose of the petition was to permit transfer of the respondent to an institution with facilities better suited to treat him. On the evening after the incident, a physician executed the first certificate required for involuntary commitment. Ill. Rev. Stat. 1981, ch. 9172, par. 3 — 602. The respondent was transferred that night to Adolph Meyer Health Center in Decatur, a state facility. The second required certificate, which must be executed by a psychiatrist (Ill. Rev. Stat. 1981, ch. 9172, pars. 3 — 602, 3 — 610), was prepared the following day. The trial court declared the respondent to be a person subject to involuntary admission to a mental health facility under the Code. Hays, 102 Ill. 2d at 316-17. We affirmed the appellate court’s reversal of the trial court. We determined that, under section 3 — 403, involuntary commitment proceedings may not be brought against a voluntarily admitted patient unless the patient has already submitted a request for discharge. We held that one of the purposes of the Code is to encourage voluntary admissions, and a patient who voluntarily undertakes therapy is more likely to be rehabilitated than one who is involuntarily required to undergo treatment. Hays, 102 Ill. 2d at 319-20. An important means of encouraging voluntary admission is to guarantee voluntary patients the right to request their discharge. Hays, 102 Ill. 2d at 320.
In In re Splett, 143 Ill. 2d 225 (1991), the respondent voluntarily admitted himself to Elgin Mental Health Center, a state facility. A month later, the State filed a petition seeking respondent’s involuntary admission. At a hearing, experts for the State testified that the respondent suffered from a bipolar disorder with psychotic features and posed a threat to himself and others. The respondent raised no challenge to the validity of the proceedings. Splett, 143 Ill. 2d at 227-28. The trial court found that the evidence of the respondent’s mental illness and potential to inflict harm upon himself and others had been established by clear and convincing evidence and that he was subject to involuntary admission. The appellate court reversed, holding that the commitment order was ineffective because the State had failed to comply with the notice requirements of the Code. Splett, 143 Ill. 2d at 228. We affirmed the appellate court but for reasons not discussed in the appellate opinion. We found that respondent was not eligible for involuntary admission because he had not submitted a written request seeking his discharge from the state mental health center to which he had been voluntarily admitted. Splett, 143 Ill. 2d at 235. The only reference in the record to a request by the respondent for discharge appeared in the certificate of one of the physicians, who stated that the respondent had “requested his discharge.” Splett, 143 Ill. 2d at 234. We stated that because the statute expressly states that a request for discharge must be in writing, an oral request is insufficient under Hays to implicate involuntary admission proceedings. Splett, 143 Ill. 2d at 234. We reiterated our belief, expressed in Hays, that section 3 — 403 is designed to protect a voluntarily admitted patient from losing control over his status. Splett, 143 Ill. 2d at 236.
Article VI allows for emergency involuntary admission to a mental health facility of a person in need of immediate hospitalization. 405 ILCS 5/3 — 600 et seq. (West 2000). Nothing in the Code expressly requires that a voluntary patient must first make a written request for discharge before a petition for involuntary admission can be filed under article VI of the Code. Our decisions in Hays and Splett that a voluntarily admitted patient must have made a written request for discharge in order to proceed with a petition for emergency involuntary admission under section 3 — 403 were based on perceived legislative intent to encourage voluntary admissions and to allow individuals to maintain a measure of control over their status. We noted in dicta in Hays that the Code fails to address a situation in which the condition of a patient voluntarily admitted to a private facility has deteriorated so that he cannot be adequately cared for at the facility and he is unable to request a discharge. Under such circumstances, we reasoned, the facility may notify public mental health authorities and release the patient into their custody to permit instituting an involuntary commitment proceeding. Hays, 102 Ill. 2d at 320-21. The problem created by this test is a determination of what deterioration is sufficient to bypass the requirement of a written request for discharge. In some cases, where the patient is completely noncommunicative or has suffered a physical disability, the deterioration of the patient’s condition clearly prevents making a written request for discharge. In the instant case, it is clear that respondent was in need of continued treatment. Respondent concedes that the findings that he had a mental illness and that he was reasonably expected to inflict serious harm upon himself or another in the near future are not against the manifest weight of the evidence. The evidence is inconclusive as to whether respondent’s condition deteriorated after his admission to St. Clare’s so that he was unable to request discharge.
However, the actions of St. Clare’s and the record make it apparent that it deemed it could no longer adequately treat respondent. The Code fails to address a situation in which a nonstate hospital, either for clinical or other reasons, cannot continue to treat a voluntary patient already admitted to the facility. A patient who can no longer be treated at a nonstate hospital may be in need of further services, but the nonstate facility, unlike a state facility, does not have the legal means by which to transfer a voluntary patient to a different facility to ensure he or she receives appropriate treatment. The nonstate facility cannot rely on the emergency procedures of article VI unless the patient has requested in writing his discharge. Article VII of the Code provides for involuntary admission to a mental health facility by court order in nonemergency situations. 405 ILCS 5/3 — 700 et seq. (West 2000). The nonstate facility cannot turn to article VII because the patient is already voluntarily hospitalized. Article VII contemplates a situation where the individual whom a petitioner seeks to have involuntarily admitted is permitted to remain at home. See 405 ILCS 5/3 — 704(a), 3 — 706 (West 2000). Under Hays, St. Clare’s would have no options other than to simply discharge respondent altogether or to continue to offer inadequate care, or care for which they would not be reimbursed, while waiting for respondent to make a written request for discharge.
We decline to interpret section 3 — 403 as operating to absolutely prevent a nonstate hospital from discharging a patient to whom it could no longer offer services. We hold that when a nonstate hospital can no longer adequately treat a voluntarily admitted patient, discharge from the nonstate hospital and the immediate initiation of an involuntary commitment proceeding to a state hospital pursuant to article VI serves to ensure that a patient receives necessary and adequate treatment. We have long held that, in construing a statute, courts presume that the General Assembly, in the enactment of legislation, did not intend absurdity, inconvenience, or injustice. Michigan Avenue National Bank v. County of Cook, 191 Ill. 2d 493, 504 (2000). We do not believe that the legislature envisioned or would have approved of an interpretation of section 3 — 403 such that when a non-state facility can no longer treat a voluntary patient in need of continued treatment, the patient could not be involuntarily committed to a state mental health facility, regardless of his condition or the threat he poses to himself or others. Such a holding would not serve the interests of the public or the patient and creates a process with potential results that are both absurd and frightening.
In so holding, we preserve the general requirement announced in Hays that a written request for discharge must precede the instituting of emergency involuntary commitment proceedings against voluntarily admitted patients. A narrow exception to this requirement arises when a nonstate hospital can no longer adequately administer psychiatric treatment to a voluntarily admitted patient. Respondent argues that this exception creates a loophole through which any petitioner, including the State, could too easily bypass the written-discharge requirements of section 3 — 403, and that any mental health facility could strip a recipient of his or her voluntary status by simply completing discharge paperwork and initiating involuntary admission proceedings simultaneously. We disagree. We do not deviate from our holdings in Hays and Splett that one of the purposes of the Code was the encouragement of voluntary admissions. Hays, 102 Ill. 2d at 320; Splett, 143 Ill. 2d at 233. We reiterate that a patient who voluntarily undertakes therapy is more likely to be rehabilitated than one who is involuntarily required to undergo treatment and that an important means of encouraging voluntary submission is to guarantee voluntary patients the right to request their discharge. Hays, 102 Ill. 2d at 319-20; Splett, 143 Ill. 2d at 233-34. However, the patient’s condition and the potential threat he or she poses to others must be considered. The public must be protected from persons dangerous because of mental illness (Hays, 102 Ill. 2d at 320), and individuals must often be protected from harming themselves. It is difficult to achieve a perfect balance between protecting the rights of the individual who has chosen to be voluntarily admitted and ensuring that the individual continues to receive adequate and necessary treatment, thus guarding against the possibility that the patient will inflict harm upon himself or the public. Judicial review of a petition seeking to involuntarily admit a voluntary patient serves to preserve an individual’s control over his or her status when possible to do so.
CONCLUSION
For the foregoing reasons, we find that the procedure followed in the instant case was proper. The judgment of the appellate court is affirmed.
Affirmed.
