Idaho Mental Health Hold Code: Criteria, Timeline, and Rights

Idaho’s mental health hold law, set out in Idaho Code Title 66, Chapter 3, allows a person to be detained involuntarily for psychiatric evaluation and treatment when there is reason to believe they are mentally ill and either pose an imminent danger to themselves or others or are gravely disabled. A peace officer or a qualified hospital clinician starts the hold, a court reviews it within 24 hours, and a full hearing must follow within five days. The person can be released at any of several checkpoints, or committed to the Department of Health and Welfare for up to one year.

When Someone Can Be Held

Two things have to be true at the same time. The person must be mentally ill, and they must be either imminently dangerous or gravely disabled because of that illness. General worry about someone’s behavior or mood is not enough.¹

Idaho Code 66-317 defines mental illness as a substantial disorder of thought, mood, perception, or orientation that grossly impairs judgment, behavior, or the ability to recognize and adapt to reality, and that requires care at a facility or through outpatient treatment.²

The second requirement is where most cases turn. “Imminently dangerous” means a threat of substantial physical harm. “Gravely disabled” is broader. Under Idaho Code 66-317, a person is gravely disabled when mental illness has caused them to demonstrate an inability to:

Meet basic physical needs for food, clothing, shelter, medical care, or safety
Protect themselves from harm or victimization by others
Maintain behavioral control sufficient to avoid serious criminal justice involvement
Recognize their own symptoms, where the person lacks insight into the need for treatment and going without treatment would likely cause deterioration until one of the conditions above is met

That last category allows a hold based on predicted deterioration rather than current inability to function, though the connection between the mental illness and the disability still has to be demonstrated.²

Who Can Start a Hold

Idaho Code 66-326 limits this authority to a short list of people:

Peace officers, including state probation and parole officers
Physicians or medical staff at a hospital where the person is already present for care
Physician assistants practicing at such a hospital
Advanced practice registered nurses practicing at such a hospital

A peace officer can take a person into custody and transport them to a facility. Hospital-based clinicians can detain someone who is already at the hospital.¹

Family members and friends cannot initiate a hold on their own. If you are worried about someone, your two practical options are calling law enforcement or a crisis line, or bringing the person to a hospital emergency department where qualified staff can evaluate whether the legal criteria are met.

Officers do not need a prior medical evaluation or court order to detain. They need “reason to believe” the person meets the criteria, based on their own observations, witness reports, or the person’s statements and behavior. Transport must use the minimum restraint necessary for safety.¹

The Timeline From Custody to Hearing

Once someone is detained, the process runs on tight, overlapping deadlines designed to get them in front of a judge within days.

Within 24 hours of custody: Evidence supporting the claim of grave disability or imminent danger must be presented to a court. If the court agrees the criteria are met, it issues a temporary custody order.³

Within 24 hours of that order: The person must be examined by a designated examiner, a psychiatrist, psychologist, psychiatric nurse, social worker, or other mental health professional qualified and designated by the Department of Health and Welfare.²

Within 24 hours of the examination: The examiner reports findings to the court. If the examiner concludes the person is mentally ill and either likely to injure themselves or others or gravely disabled, the prosecuting attorney files a petition for continued detention and commitment proceedings within 24 hours of the examination.¹

Within five days of the detention order: The court must hold a hearing on the petition. That five-day window includes weekends and holidays.¹

At no point during any of this can the person be held in a jail or other nonmedical detention unit. The statute is explicit, and the rule applies from initial custody through any commitment that follows.

What Happens at the Commitment Hearing

The commitment hearing follows rules similar to other civil proceedings. The proposed patient has the right to an attorney, and the court appoints one for anyone who cannot afford representation. Both sides can present evidence, call witnesses, and cross-examine. The patient can waive their own presence after consulting with their attorney, and the court can excuse the patient if attending would harm their physical or mental health.

The standard of proof is clear and convincing evidence, higher than the preponderance standard used in most civil cases. The court must find that the person is mentally ill and, because of that illness, is either likely to injure themselves or others or is gravely disabled. If the court makes that finding, it orders the person committed to the custody of the Department of Health and Welfare for an indeterminate period not to exceed one year.⁴

The court can also hold proceedings in abeyance for up to 30 days rather than ordering immediate commitment, which functions as a middle ground when a voluntary treatment arrangement looks possible.

If the court does not find clear and convincing evidence, the person must be released immediately. There is no discretion.

Rights While Detained

A person under a hold keeps important rights throughout the process:

Written notice explaining the legal basis for the hold and the right to contest it
An attorney at every stage, including a court-appointed attorney if they cannot afford one
Contact with family, legal counsel, and advocates
Placement in a medical facility, never in a jail or unit used for criminal defendants
A hearing at which they can present evidence and cross-examine witnesses

Involuntary medication is a separate legal question from involuntary detention. Being placed on a hold does not by itself authorize the facility to administer psychiatric medication against the person’s will. Forced medication generally requires either a separate court order or a genuine medical emergency where immediate intervention is needed to prevent serious harm, supported by clear and convincing evidence.

Outpatient Commitment as an Alternative

Idaho Code 66-339B allows outpatient commitment as a less restrictive alternative to hospitalization. It applies when someone has a history of mental illness, a treatment plan outpatient services can satisfy, and has failed to comply with prescribed treatment on at least one occasion.⁵

The court must find by clear and convincing evidence that the person has a mental illness, has failed to follow a prescribed course of treatment at least once, and that this noncompliance has caused or will cause deterioration to the point where the person becomes likely to injure themselves or others, or becomes gravely disabled. Outpatient commitment also cannot exceed one year.⁵

An outpatient commitment order gives the Department of Health and Welfare continuing authority to transport the person to treatment and to take steps to obtain compliance. Repeated violations can lead the department to seek conversion to inpatient commitment.

Who Pays

The costs of commitment proceedings, examiner fees, transportation, and psychiatric and hospital care fall first on the person being held, their spouse, or their adult children. Insurance and Medicaid are applied before anyone pays out of pocket. If the court finds the person indigent after considering income and resources, the county of residence covers what other sources do not.⁶

After formal commitment to state custody, the Department of Health and Welfare takes over cost responsibility beginning the day after it receives notice of the commitment. If the county fails to transport the person to a state facility within 24 hours of written notice that a bed is available, the county stays on the hook.⁶

Firearm Consequences After Commitment

A formal commitment carries a lasting federal consequence. Under 18 U.S.C. § 922(g)(4), anyone who has been committed to a mental institution is permanently prohibited from possessing firearms or ammunition.⁷

The distinction between a short-term emergency hold and a full court-ordered commitment matters. A brief detention under Idaho Code 66-326 that ends before or during the initial evaluation process generally does not trigger the federal firearm prohibition. A formal commitment order under Idaho Code 66-329 does. Restoring firearm rights after a commitment requires a determination by a court, board, commission, or other lawful authority that the person has been restored to mental competency and no longer suffers from a mental disorder.⁸

How the Hold Can End

Most people detained under an emergency hold are not ultimately committed for a full year. The hold can end at any of these points:

The court is not persuaded by the initial 24-hour evidence and declines to issue a temporary custody order
The designated examiner finds the person does not meet the criteria, and no petition is filed
The court does not find clear and convincing evidence at the full hearing and orders immediate release
The court orders inpatient commitment to the Department of Health and Welfare for up to one year
The court orders outpatient commitment for up to one year under strict conditions
The court holds proceedings in abeyance for up to 30 days, often to see whether voluntary treatment takes hold

A commitment order remains in effect until a court formally terminates it, even if the person is conditionally released or the treatment setting changes. Someone who improves can petition the court for early termination. Doing well on medication or participating in treatment voluntarily does not, by itself, end a commitment; only a court order can.
