What is the ITA Court?

Under Washington Law, mentally disordered persons may be civilly committed to hospital or treatment settings, if a Superior Court judicial officer (judge or commissioner) finds that they pose a threat to themselves or others due to exhibited symptoms of mental illness. Each year roughly 4000 involuntary commitment petitions are filed in King County Superior Court.

PLEASE NOTE: This court is not the same as King County District Court's Mental Health Court or Seattle Municipal Court's Mental Health Court. Those courts handle criminal cases. Superior Court handles civil commitments.
