IN THE COURT OF APPEALS OF THE STATE OF WASHINGTON

In the Matter of the Detention of No. 88310-1-I

M.K., DIVISION ONE

UNPUBLISHED OPINION Appellant.

DÍAZ, J. — A trial court committed M.K. to 14 days of involuntary detention

pursuant to the involuntary treatment act (ITA), chapter 71.05 RCW. M.K. now

argues the State failed to adduce sufficient evidence proving she was gravely

disabled. Disagreeing, we affirm.

I. BACKGROUND

In April 2025, a designated crisis responder (DCR) petitioned for an initial

120-hour period of treatment for M.K. after her mother, Ruth, referred her for

evaluation. The DCR noted that M.K. had been detained twice before under similar

circumstances because she was unable to care for herself without assistance. The

DCR indicated M.K. had recently been responding to internal stimuli, had become

incontinent, and was no longer connected to outpatient services or taking her

antipsychotic medication. Thereafter, treating mental health professionals at No. 88310-1-I/2

Fairfax Hospital (Fairfax) sought to commit M.K. for 14 more days. A superior court

held a hearing on the petition in May 2025.

After hearing testimony from M.K.’s mother and a Fairfax Hospital court

evaluator, a commissioner of the court entered an order which found the State

successfully proved by a preponderance that M.K. was gravely disabled. The

court’s written order detailed findings and conclusions from the witnesses’

testimony and incorporated its oral rulings from the hearing. The court ordered an

additional 14 days of commitment at Fairfax. M.K. timely appeals. 1

II. ANALYSIS

Under the ITA, a court may grant a petition seeking up to 14 days of

involuntary commitment if, at the conclusion of a probable cause hearing, it finds

by a preponderance of the evidence that a person is, inter alia, “gravely disabled”

as the result of a behavioral health disorder. RCW 71.05.240(4)(a); see also In re

Welfare of Sego, 82 Wn.2d 736, 739 n. 2, 513 P.2d 831 (1973) (defining

preponderance of the evidence as “more probably true than not”).

Our review “is limited to determining whether substantial evidence supports

the findings and, if so, whether the findings in turn support the trial court's

conclusions of law and judgment.” In re Det. of LaBelle, 107 Wn.2d 196, 209, 728

P.2d 138 (1986). Substantial evidence is a quantum of evidence sufficient to

persuade a fair-minded person. In re Det. of A.F., 20 Wn. App. 2d 115, 125, 498

P.3d 1006 (2021). In such a review, we do not disturb a trial court’s determinations

as to credibility or the persuasiveness of evidence. Id. If there is evidence

sufficient to satisfy this standard, we may not substitute our judgment for the fact

finder’s. In re Meistrell, 47 Wn. App. 100, 109, 733 P.2d 1004 (1987) (reiterating

the same rule in a civil commitment case).

The ITA provides two alternate definitions of “gravely disabled.” The term

means:

a condition in which a person, as a result of a behavioral health disorder: (a) [i]s in danger of serious physical harm resulting from a failure to provide for his or her essential human needs of health or safety; or (b) manifests severe deterioration in routine functioning evidenced by repeated and escalating loss of cognitive or volitional control over his or her actions and is not receiving such care as is essential for his or her health or safety.

RCW 71.05.020(25).

Our Supreme Court has required a petitioner to make several showings to

satisfy this second prong. LaBelle, 107 Wn.2d at 208. Namely, there must be

some factual basis for concluding the respondent (1) had experienced a severe

deterioration in routine functioning including recent proof of significant loss of

cognitive or volitional control, and (2) would not receive care essential for her

health or safety if released. Id. To prove the latter, the Court explained, “[T]he

evidence should indicate the harmful consequences likely to follow if involuntary

treatment is not ordered.” Id. Finally, it noted the definition implicitly requires some

showing that the respondent is “unable . . . to make a rational decision with respect

to [their] need for treatment.” Id. (emphasis omitted).

3 No. 88310-1-I/4

We hold there is substantial evidence in this record to meet each of these

components of RCW 71.05.020(25)(b). 2

With regard to a deterioration in functioning, there was an ample factual

basis for concluding M.K.’s mental state had seriously devolved. See LaBelle, 107

Wn.2d at 208. Namely, her mother testified that M.K. had been hospitalized three

times over the previous three years and—after she had refused to continue with

outpatient treatment, but before the referral in the present case—she again had

become unable to care for her basic needs. M.K. had become incontinent, was

not sleeping, and could not feed herself. For example, M.K. had burned pots while

trying to cook and her mother disconnected the stove for her safety.

Moreover, the court evaluator testified that M.K. had not been taking her

medication prior to her most recent hospitalization. When M.K. is medicated and

treated and she is fully at her baseline, her mother explained she can take care of

her hygienic needs, sleep, and cook for herself. She also reported that when M.K.

is stabilized, she does not experience delusions, which she had been experiencing

again recently.

As to whether M.K. would receive care essential for her health or safety if

released, the testimony at the hearing also provided a factual basis to conclude

M.K. would not if released. See LaBelle, 107 Wn.2d at 208. Specifically, the court

evaluator introduced hospital records documenting that only days before the

2 Because RCW 71.05.020(25) sets out two independent bases for concluding a

person is gravely disabled, we need not also assess the evidentiary support for the definition in subsection (a). See LaMon v. Butler, 112 Wn.2d 193, 200-01, 770 P.2d 1027 (1989) (holding we may affirm on any basis supported by the record.) 4 No. 88310-1-I/5

hearing, M.K. was still exhibiting active symptoms, including withdrawal, delusions,

and apparently not taking care of her hygiene. Though she had shown some signs

of improvement since admission, she still needed assistance completing activities

of daily living and prompting to take her medications.

Relatedly, her mother opined that, after her second stint in the hospital, M.K.

had severely regressed within just three weeks of her release. This testimony

about M.K.’s recent, rapid deterioration under similar circumstances served to
