[¶ 1] Virginia Green appeals from the denial by the Superior Court (Kennebec County, Atwood, J.) of her petition for release from the Augusta Mental Health Institute (AMHI) and from the denial of her motion to alter or amend the court’s judgment. Green was committed to AMHI on July 10, 1997, after she was found to be not criminally responsible by reason of mental disease or defect for the killing of her mother. On appeal, Green argues that the allocation of the burden of proof by clear and convincing evidence to insanity acquittees in release proceedings violates her right to substantive and procedural due process, as well as her right to equal protection. She also argues that the court erred as a matter of law when it applied the statutory criteria for release and that the court’s findings of fact are *1268 clearly erroneous. Because we find that the allocation of the burden of proof passes constitutional muster and because we find no error in the court’s judgment, we affirm.
I. FACTS
[¶ 2] On November 27, 1996, Virginia Green killed her mother while in a psychotic and delusional state. She was placed in AMHI in February 1997 pending the outcome of her trial. In July 1997, she was found not criminally responsible by reason of insanity and was automatically committed to AMHI pursuant to 15 M.R.S.A. § 103 (Supp.1999). In October 1997, Green filed a petition for release to a residential treatment program. A hearing was not held on her petition, however, until November 1998 because of various delays.
[¶ 3] Prior to the hearing, Green filed a trial memorandum challenging the placement of the burden of proof on her as a petitioner and requested that the burden be placed on the State to justify her continued commitment. The court denied her request citing our decision in
Taylor v. Commissioner of Mental Health and Mental Ret.,
[¶ 4] In addition to the testimony of Green herself, the evidence at the hearing consisted almost exclusively of testimony by experts regarding Green’s mental health and her potential for dangerousness if released to a program like the one she proposed in her petition for release. It is undisputed that Green suffers from bipolar disorder, also known as manic depressive illness, and poly-substance abuse, which together are referred to as a dual diagnosis condition. It is also undisputed that her illness is incurable and will last a lifetime.
[¶ 5] Her treating psychiatrist at AMHI, Dr. Walter Christie, testified that she will always suffer from mental illness, but that she is currently asymptomatic. It was Dr. Christie who developed the transition plan that Green proposed to the court, as well as additional “steps” to the transition plan that were later provided at the court’s request. Dr. Christie also testified that Green had a pattern of relapses and hospitalizations, indicating that she had been hospitalized fifteen to twenty times since 1972.
[¶ 6] Nevertheless, Dr. Christie opined that Green could safely be returned to the community without a likelihood of harm to herself or others as long as the proposed treatment plan was followed strictly. He was confident that Green could safely make the jump from being restricted to the grounds of AMHI to a residential treatment program. Dr. Christie observed that the combination of Green’s substance abuse and her bipolar illness precipitated her mania that eventually evolved in psychosis and delusion. He testified that the events leading up to the death of her mother represented an extreme state for Green that could have been avoided with proper treatment and oversight like that provided for in the plan.
[¶ 7] Green testified that in the past she had used drugs and alcohol in an effort to self-medicate despite her awareness that they precipitated psychotic and delusional episodes, but that she would never again resort to those tactics because they had led to the death of her mother. Green did acknowledge, however, that her illnesses are prone to relapse.
[¶ 8] Dr. Prudence Baxter, a forensic psychiatrist, prepared an independent psychiatric examination of Green at AMHI’s request and conducted a general review of Green’s case. She concluded that Green was not an appropriate candidate for release from the hospital, even in a supervised living situation like the one proposed. She expressed concerns that much of Green’s treatment at AMHI had been fo-cussed on gaining discharge from the hospital and had not sufficiently explored why *1269 Green’s most recent episode of psychosis had resulted in such an extreme outcome. She was also concerned about Green’s anti-anxiety medication that had highly addictive properties given her diagnosis of poly-substance abuse. Lastly, she indicated that she had not seen a residential treatment plan like the one proposed implemented in a forensic setting in the absence of any data regarding a candidate’s responses to more incremental increases in privileges.
[¶ 9] Dr. Ann Bower, the clinical director for the Department of Mental Health, Mental Retardation and Substance Abuse Services, expressed similar concerns regarding the absence of demonstrable evidence that Green was ready for such a reduction in supervision. She indicated that such plans, known as “out-patient commitment plans,” are rare in Maine because the State lacks an effective enforcement mechanism in the event of a breakdown in compliance. Dr. Bower also had concerns regarding analgesics that Green had been prescribed because of their addictive qualities.
[¶ 10] Following the testimony, the court issued an order in which it denied Green’s petition for release, but noted that a higher level of privileges might be appropriate for Green. Green then filed a motion to amend the judgment, seeking an order granting off-grounds privileges. The State opposed the motion and submitted an institutional report recommending off-grounds privileges of a more circumscribed nature. The court denied Green’s motion to amend the judgment and accepted the report’s recommendation, approving the increased privileges it outlined including the more limited off-grounds privileges. Green then filed a notice of appeal.
II. THE BURDEN OF PROOF
[¶ 11] If a defendant is determined to be not criminally responsible by reason of mental disease or defect pursuant to 17-A M.R.S.A. § 39 (Supp.1999), the person is automatically committed to the custody of the Commissioner of Mental Health. See 15 M.R.S.A. § 103 (Supp.1999). Generally, the State must carry the burden beyond a reasonable doubt that the defendant engaged in conduct constituting a crime after which the burden shifts to the defendant to prove lack of criminal responsibility by reason of mental disease or defect by a preponderance of the evidence. 1 See 17-A M.R.S.A. §§ 39 & 40 (1983 & Supp.1999). The statute governing release of insanity acquittees, however, does not provide for a standard of proof, nor does it provide on whom the burden of proof rests. See 15 M.R.S.A. § 104-A (Supp.1999). As a result, we have been forced to make that determination in the past.
[¶ 12] In
State v. Shackford,
*1270 A. ' Substantive Due Process
[¶ 18] Green argues that placing the burden on her to show by clear and convincing evidence that she is either no longer mentally ill or no longer harbors a potential for dangerousness violates her right to substantive due process provided by the Maine and United States Constitutions. 2 We conclude that placing such a burden on an insanity acquittee in release proceedings neither offends common concepts of ordered liberty, nor is such an arbitrary and wrongful government action that it violates either the Maine or United States constitutions.
The United States Supreme Court has stated:
Our established method of substantive-due-process analysis has two primary features: First, we have regularly observed that the Due Process Clause specially protects those fundamental rights and liberties which are, objectively, deeply rooted in this Nation’s history and tradition, and implicit in the concept of ordered liberty, such that neither liberty nor justice would exist if they were sacrificed. Second, we have required in substantive-due-process cases a careful description of the asserted fundamental liberty interest. Our Nation’s history, legal traditions, and practices thus provide the crucial guideposts for responsible decisionmaking that direct and restrain our exposition of the Due Process Clause.
Washington v. Glucksberg,
[¶ 14] Green relies heavily on
Foucha
for her proposition that the allocation and degree of proof in a release proceeding violates substantive due process. However, as the United States Supreme Court has admonished, we first must have a careful description of the asserted fundamental interest. In
Foucha,
an insanity acquittee challenged a Louisiana statute that allowed for the indefinite commitment of individuals who although dangerous, were no longer mentally ill.
Id.
at 73,
[¶ 15] It is well established that the State may confine someone who is both mentally ill and who poses a danger to society.
See Jones v. United States,
463
*1271
U.S. 354, 370,
[¶ 16] Green cites no authority, and we find none, that stands for the proposition that once an individual has been properly committed, that individual possesses a substantive due process right to be free from bearing the burden of proof in subsequent release proceedings. Again, we stress that Green is not arguing that her continued confinement is an arbitrary and wrongful governmental action; as someone who has been adjudged both mentally ill and dangerous, she does not possess a fundamental right to be free from confinement. Rather, she merely argues that the allocation of the burden of proof is arbitrary and wrongful government action. We do not agree, however, that placing the burden on an insanity acquittee in a release proceeding is somehow repugnant to our notion of ordered liberty; therefore, doing so does not violate Green’s right to substantive due process. 3
B. Procedural Due Process
[¶ 17] Green also argues that the placement of the burden and degree of proof in release proceedings does not comport with her right to procedural due process. The first step in procedural due process analysis is to identify whether there is an interest to be protected.
See Mathews v. Eldridge,
[¶ 18] Once a protected interest is established, that interest receives constitutionally required procedural protection.
See Vitek v. Jones,
[¶ 19] The Court also noted that, for purposes of initial automatic commitment of insanity acquittees, the finding beyond a reasonable doubt that the acquit-tee committed a crime is a sufficient indication of dangerousness and that an insanity acquittal supported an inference of continuing mental illness.
See id.
at 365-66,
[¶ 20] Furthermore, the State clearly has an interest, for reasons of public safety, in avoiding erroneous release.
See Wallace,
C. Equal Protection
[¶ 21] Green argues that the disparity in the allocation and degree of proof at release proceedings for civil committees and those for insanity acquittees violates her right to equal protection guaranteed by the Maine and United States Constitutions.
4
We have noted previously, “[i]f a challenged statute involves neither a fundamental right nor a suspect class, different treatment accorded to similarly situated persons need only be rationally related to a legitimate state interest.”
See School Admin. Dist. No. 1,
[¶ 22] Allocating the burden of proof to insanity acquittees by clear and convincing evidence in release proceedings, while not doing so to civil committees, does not impinge on a fundamental right, nor are insanity acquittees considered members of a suspect classification, therefore, strict scrutiny does not apply. Rather, we must determine whether similarly situated individuals are being treated differently and whether there is a rational basis for it.
See City of Cleburne, Texas v. Cleburne Living Center,
[¶ 23] Insanity acquittees have previously demonstrated their dangerousness to the community. The danger posed by civil committees is more speculative. This distinction does not change once commitment has taken place. As a result, insanity acquittees pose an increased risk to society once they are released and this provides a rational basis for the disparity in treatment.
Cf. Francis S. v. Stone,
[¶24] Because the placement and the degree of the burden of proof in release proceedings do not violate insanity acquit-tees’ rights to due process and equal protection, we conclude that our ruling in Taylor is constitutionally sound. Therefore, our decision in that case will remain undisturbed. The Superior Court properly adhered to Taylor in the hearing on Green’s petition for release.
III. GREEN’S RELEASE HEARING
A. The Governing Statute
[¶ 25] With respect to the release proceedings themselves, Green argues that the court misinterpreted the statutory requirements for release when it determined that because she was still diagnosed with a mental illness and still posed a likelihood of danger to the community, she was not eligible for release. She argues that the statute requires that an insanity acquit-tee’s illness be symptomatic in order to continue commitment, and that if the illness is no longer symptomatic, the statute requires release.
[¶ 26] Statutory interpretation is a question of law and we review such questions de novo.
See Passamaquoddy Water Dist. v. City of Eastport,
If, after hearing, the court finds that the person may be released or discharged without likelihood that the person will cause injury to that person or others due to mental disease or mental defect, the court shall order as applicable ... [r]elease from the institution, provided that ... [t]he order for release may include conditions deemed appropriate by the court ....
15 M.R.SA.. § 104-A(1)(A) (Supp.1999) (emphasis added). As we noted in
LaDew v. Commissioner of Mental Health and Mental Retardation,
the provisions of the Criminal Code regarding the insanity defense must be read and applied as an
*1274
integrated whole with those of Title 15 regarding the release of insanity acquit-tees.
See LaDew,
[¶ 27] Because the release provisions provide no definition of “mental disease or defect,” we look to the Criminal Code which provides the following definition: “ ‘mental disease or defect’ means only those severely abnormal mental conditions that grossly and demonstrably impair a person’s perception or understanding of reality.” 17-A M.R.S.A. § 39(2) (Supp.1999). We stated in
LaDew
that “to be released under 15 M.R.S.A. § 104-A [an insanity] acquittee must show ... that the mental disease or defect by reason of which he was relieved of criminal responsibility
no longer exists,
or at least
no longer poses a danger
to himself or others if he is released.”
LaDew,
[¶ 28] Although demonstrating that a mental illness is asymptomatic or that the insanity acquittee is no longer in the same state as existed at the time of the acquittee’s crime may indicate that there is little likelihood of dangerousness, it does not mean that the mental “disease or defect”
no longer exists. Cf. Parrish v. Colorado,
[¶ 29] The trial court in this case denied Green’s request for relief based on its finding that (1) Green still suffers from mental illness that will be life-long, although she is currently stable because of her regimen of medication, and (2) at the present time she could not be released without the likelihood of danger to herself or others. In other words, the mental condition that impaired Green’s perception of reality when she killed her mother, i.e., the dual diagnosis of her bipolar and poly-substance abuse illnesses, still existed, and that condition still created the potential for danger at the time of the hearing. Thus, the court did not err as a matter of law by denying Green release based on these factual determinations.
B. The Court’s Factual Findings
[¶ 30] In Green’s last challenge to the court’s judgment she argues that there is insufficient evidence to support the court’s findings of fact. We review findings of fact for clear error and will reverse a finding of fact only when:
(1) there is no competent evidence in the record to support it, or (2) it is based upon a clear misapprehension by the trial court of the meaning of the evidence, or (3) the force and effect of the evidence, taken as a total entity, rationally persuades to a certainty that the finding is so against the great preponderance of the believable evidence that it does not represent the truth and right of the case.
*1275
State v. Landry,
[¶ 31] We have previously noted, “[w]hether [the insanity acquittee] suffer[s] from a mental disease or defect is ultimately a legal, as opposed to a medical, determination to be made by the court.”
Roberts,
[¶ 32] With respect to the likelihood of dangerousness, again the court had before it evidence that the symptoms of Green’s bipolar illness were controlled by strong medications some of which had addictive properties and might present problems with respect to her poly-substance abuse disorder. The testimony of all of the witnesses, including Green herself, indicated a long history of relapses and hospitalizations, often precipitated by the abuse of substances, licit and illicit. Several of the witnesses expressed concern over the lack of data regarding any attempts at a more gradual reintroduction of Green in the community setting. In other words, there was no precedent in Green’s treatment history subsequent to her lulling her mother for establishing Green’s risk of dangerousness off the ground of AMHI. The record evidence at this stage in Green’s treatment did not compel a finding by the court that Green presented no likelihood of danger to herself and others. 5
[¶ 33] Because there is competent evidence in the record supporting the court’s factual findings, we find no error. Furthermore, the court correctly interpreted the statute governing release. Finally, as discussed above, our holding in Taylor regarding the burden of proof in release proceedings does not offend constitutional principles of fairness and justice.
The entry is:
Judgment affirmed.
Notes
. In this case. Green and the State reached a plea agreement establishing these elements.
. Because the due process protections of the Maine Constitution are coextensive with those “of the United States Constitution,
see Fichter v. Board of Envtl. Protection,
. In the context of her substantive due process challenge to the burden of proof, Green also argues that because she is asymptomatic, she is no longer "legally insane” and therefore has a substantive due process right not to bear the burden of proof at her release proceeding. However, the question of whether she is still mentally ill as defined by statute is one of the very questions to be answered at the release proceeding, and if she is no longer mentally ill as defined by statute, she is legally entitled to
release. See
15 M.R.S.A. § 104-A(1) (Supp.1999);
LaDew v. Commissioner of Mental Health and Ret.,
. Similar to the due process clauses of the Maine and United States constitutions, the equal protection clauses found in the state and federal constitutions offer coextensive protections.
See School Admin. Dist. No. 1 v. Commissioner, Dep't of Educ.,
. Green also argues that the court abdicated its responsibility by not adding additional conditions to the proposed release plan pursuant to 15 M.R.S.A. § 104-A(1)(A) to allay its concerns regarding Green's potential for dangerousness. Because, however, the court determined that Green still suffered from a mental illness and could not be released, i.e., returned to permanent residency within the community, without the likelihood of injury to herself or others, release was not authorized by section 104-A(1), with or without additional conditions to those proposed by Green. Additionally, the court, did approve the modified release treatment plan pursuant to section 104-A(2) recommended in the institutional report. This plan does allow for travel by Green off the ground of AMHI and in the community, but in a more measured way and with greater supervision than that proposed by Green. Therefore, the court clearly met its statutory responsibility, as it ultimately adopted a treatment plan that provided for interaction with the community, but with safeguards it implicitly deemed appropriate.
