The head of a treatment facility or other person may file a petition pursuant to Kan. Stat. Ann. §§ 59-2957 and amendments thereto seeking involuntary commitment of a voluntary patient who now lacks capacity to make an informed decision concerning treatment and who is refusing reasonable treatment efforts or has requested discharge from the treatment facility. A petition filed by the head of a state psychiatric hospital, or such person’s designee, accompanied by a statement from a physician or psychologist employed at the hospital that the physician or psychologist believes the person to be a mentally ill person subject to involuntary commitment does not need to be accompanied by a written statement from a qualified mental health professional authorizing admission to a state psychiatric hospital.
