229.3  Discharge of voluntary patients.
  Any voluntary patient who has recovered, or whose hospitalization the chief medical officer of the hospital determines is no longer advisable, shall be discharged. Any voluntary patient may be discharged if to do so would in the judgment of the chief medical officer contribute to the most effective use of the hospital in the care and treatment of that patient and of other persons with mental illness.
