King County Mental Health Ruling Upheld: Prior Illness History Not Required for Commitment

The Washington State Court of Appeals upheld a King County judge’s involuntary commitment order on Monday, establishing a key legal precedent that a documented history of mental illness is not required for the state to deem someone “gravely disabled” and mandate treatment.

The published opinion from the state Court of Appeals Division I stems from the October 2024 hospitalization of a 28-year-old nursing student, identified in court documents only by the initials H.T.

According to the May 4 ruling, H.T. had no prior history of mental health issues or medication and had been living independently before her mental state rapidly deteriorated in the fall of 2024.

Court records state that after five weeks of diminished sleep and eating, H.T. drove alone to an airport at 2:00 a.m. She called her parents from the airport, telling them that world forces were getting very dangerous and she wanted her family to escape with her.

Her parents brought her home with the assistance of police, and the following day, H.T. asked to go to the hospital. That visit to a local emergency room eventually led to her admission at Fairfax Behavioral Health, a psychiatric facility in King County.

After a hearing, King County Superior Court Judge Richard Louis Warner granted the hospital’s petition to hold H.T. for 14 days of involuntary treatment.

On appeal, H.T.’s Seattle-based appellate counsel from Nielsen Koch & Grannis argued the commitment was legally unsupported.

State law defines “gravely disabled” in part by a “repeated and escalating loss of cognitive or volitional control,” language the defense argued implied the necessity of a prior, established history of mental health episodes or hospitalizations.

The King County Prosecuting Attorney’s Office, representing the state, argued that such a narrow interpretation of the law was inaccurate.

The three-judge appellate panel sided with King County prosecutors.

Writing for the court, Judge Lori Smith noted that strictly requiring a history of hospitalization defeats the legislature’s intent to allow state intervention before a mentally ill person’s condition reaches crisis proportions.

“Repeated and escalating loss of control is not exclusive to a history of mental illness episodes and can also be proven through behavior over the course of a couple of days,” Smith wrote in the opinion, which was joined by Judges Bill Bowman and Linda Coburn.

The court found that H.T.’s rapid deterioration over five weeks—and her subsequent erratic behavior during treatment, including refusing medication and attempting to flee the hospital—provided substantial evidence of a grave disability requiring immediate intervention.
