1. The hearing for a ninety-day inpatient detention and treatment period or for outpatient detention and treatment for a period not to exceed one hundred eighty days shall be conducted in as informal a manner as may be consistent with orderly procedure and in a physical setting not likely to have a harmful effect on the mental health of the respondent. If a jury trial is not requested, due consideration shall be given by the court to holding a hearing at the mental health program. The hearing shall be held in accordance with the provisions set forth in section 632.335.

2. The burden of proof at the hearing shall be by clear and convincing evidence and shall be upon the petitioner.

3. If the matter is tried before a jury, the jury shall determine and shall be instructed only upon the issues of whether or not the respondent is mentally ill and, as a result, presents a likelihood of serious harm to himself or others. The remaining procedures for the jury trial shall be as in other civil matters.

4. The respondent shall not be required to file an answer or other responsive pleading.

5. At the conclusion of the hearing, if the court or jury finds that the respondent, as the result of mental illness, presents a likelihood of serious harm to himself or to others, and the court finds that a program appropriate to handle the respondent’s condition has agreed to accept him, the court shall order the respondent to be detained for involuntary treatment in the least restrictive environment for a period not to exceed ninety days or for outpatient detention and treatment under the supervision of a mental health program in the least restrictive environment for a period not to exceed one hundred eighty days.
