This is an appeal from the denial of a Petition for Writ of Habeas Corpus in the Pulaski County Chancery Court. Appellant was admitted to the state hospital as a voluntary patient by her guardian and subsequently sought release through a petition for habeas corpus. The chancery court refused to grant the petition because the guardian was not a party to the proceeding.
The question to be determined is whether a guardian may voluntarily confine her ward as a patient in the state hospital against the wishes of the ward and without the ward’s consent or a probate court hearing. We do not believe a voluntary admission may be converted to an involuntary commitment without due process of law. Therefore, the writ should have been granted.
*36On May 10, 1979, Ute Patterson, the daughter of Anne Kay Von Luce, petitioned the Washington Probate Court for appointment of herself as guardian of her mother. On the same date an order appointing the daughter as temporary guardian was issued by the court. The order simply stated that petitioner was an “incompetent.” There was an unverified letter from a doctor to the effect that in his opinion Mrs. Von Luce was an “incompetent.” The court issued a summons on the same day but it was not served on Mrs. Von Luce until 5 days later. The summons contained the usual 20-day return provisions. However, 4 days after the order appointing the guardian she voluntarily admitted her mother into the state hospital in Little Rock. On June 6, 1979, the ward filed a petition in the Pulaski County Chancery Court seeking a writ of habeas corpus. A hearing was held on the petition the following day and the court, although finding the ward illegally detained, refused to grant the petition because the guardian was not a party to the action. At this hearing the only authorization for holding the incompetent as a patient was an application for voluntary commitment which had been executed by the guardian on behalf of the ward. On the face of this application were the following words:
NOTE: Arkansas statutes provide that a person may not be held on a voluntary statement against his/her will unless considered homicidal, suicidal, or gravely disabled as defined by law.
There was no order of commitment or any evidence or testimony indicating the petitioner had received notification or been granted a hearing. The order from the Washington Probate Court appointing the guardian was introduced into evidence along with the unverified statement of the doctor which had been presented to the Washington Probate Court. The state hospital did not offer any testimony or other evidence indicating a need for confinement.
On June 20,1979, this Court granted petitioner’s release from the state hospital on application for temporary relief. The ward was released to her guardian and subsequently returned to her home in Washington County. So far as we know, the temporary order of guardianship has expired. *37Ordinarily, we would consider this question moot; however, due to the likelihood of such incidents being repeated and the unlikelihood that a decision can be reached on appeal before a temporary guardianship is terminated, we treat the question as one to be considered on the merits as they existed at the time the petition for habeas corpus was heard.
Even if a guardian may voluntarily admit a ward without a hearing or order, when the ward expresses a desire to leave the hospital it is a different situation. If the guardian were permitted to refuse the ward’s wishes, then the voluntary admission would become an involuntary one as it relates to the ward. To allow such confinement would contravene the statutory and constitutional safeguards afforded to the mentally ill. The writ of habeas corpus is the primary means by which a detainee may test the legal authority of his custodian. Appellee frankly admits the Pulaski County Chancery Court is the proper forum for such proceedings. Also, it is tacitly admitted the probate order appointing the guardian was of doubtful validity. Since the order has expired, we will not examine that proceeding.
The fact that the custodian held authority to release petitioner was of little comfort in view of the fact that she was held until this Court ordered her release on June 20, 1979. 1979 Ark. Acts No. 817 provide that nothing in the act shall in any way restrict the rights of any person to attempt to secure their release by habeas corpus as provided by the current Arkansas law. The habeas corpus petition has been used to obtain the release of a confinee in the state hospital. Rowland v. Rogers, 199 Ark. 1041, 137 S.W. 2d 246 (1940). Ark. Stat. Ann. § 34-1733 (Repl. 1962) states:
If it appear that the prisoner is in custody by virtue of process from any court legally constituted, or issued by any officer in the exercise of judicial proceedings before him, such prisoner can only be discharged in one (1) of the following cases:
First. Where the jurisdiction of such court or officer has been exceeded, either as to matter, place, sum or person.
*38Second. Where, though the original imprisonment was lawful, yet, by some act, omission or event which has taken place afterward, the party has become entitled to his discharge.
Third. Where the process is defective in some matter or substance required by law, rendering such process void.

The state hospital held no order of any kind which authorized it to detain the petitioner. The only authorization at all was the application completed by the guardian. By no stretch of the imagination can it be said that this application was authority to hold the petitioner against her will. The Arkansas General Assembly treated this subject extensively in Act 817 of 1979. None of the provisions of this Act were followed. Section 3 (A)(B) of Act 817 states:
* *
(A) Any person who believes himself to be suffering from a mental illness, disease or disorder may make application in writing himself or by his guardian . . .
(B) If at any time the patient who has voluntarily admitted himself or herself to the hospital makes a request to leave, and the Commissioner or his designee or the official in charge of the hospital or his designee determines that the patient is at that time homicidal, suicidal or gravely disabled, then the patient shall be considered to be held involuntarily and the commitment procedures set forth herein shall apply.
* * *
In an involuntary case a hearing must be held within 7 days. The only hearing was on the petitioner’s request for habeas corpus.
Mental illness alone is not justification for a guardian or *39a state to lock a person up. There must be a meaningful hearing in accordance with due process before such action is authorized. Wessel v. Pryor, 461 F. Supp. 1144 (Ed. Ark. 1978); O’Connor v. Donaldson, 422 U.S. 563 (1975). It was stated on the face of the application for voluntary admission that a patient could not be held against his wishes unless the patient was considered homicidal, suicidal, or gravely disabled. In this case there has simply been no attempt on the part of anyone to comply with the provisions of any Arkansas law as it relates to involuntary commitment. Not even a mentally ill person may be confined against his will unless he is afforded due process of law. Act 817 provides that before a person may be committed for 30 days or more there must be a hearing at which clear and convincing evidence is presented to the effect that the ward or detainee is homicidal, suicidal, or gravely disabled. We are not unaware of the problem of society and the mentally ill. The welfare of the people and the mental patient must both be given careful attention. The best interest of both must be weighed and taken into consideration when the question of confinement is at issue. If we were not to require at least substantial compliance with the law to fully protect the rights of incompetents it would be possible for an unscrupulous person to have himself appointed as guardian and then lock his ward in a mental institution and proceed to waste the ward’s estate. If a state and the judiciary are not vigilant in the protection of the rights of incompetents it is likely to lead to the abuse of the person and estate of such incompetents. The mentally ill are unable to think and care for themselves in a normal manner and of necessity depend upon the state and the courts for protection. Although due process safeguards do not extend to the voluntary committee they most definitely extend to involuntary detainees. When a voluntary patient seeks relief he must be released or henceforth treated as an involuntary detainee in which case the due process safeguards most definitely apply. We have no choice on the record before us other than to treat petitioner as an involuntary detainee and must hold in this case that the ward was not afforded either procedural or substantive due process. Therefore, the court should have granted the petition for habeas corpus.
Reversed and remanded.
