Thanks for finding that. Actually, by my reading, the linked Title 44 says that a competent person may refuse medication except in emergency situations or
"as permitted under applicable law for a person committed by a court to a treatment program or facility." But it says nothing about what or where the "applicable law" re: involuntary commitment is, and I haven't been able to find anything on line (I found the section of Title 44 regarding involuntary commitment, and that section says nothing about medications -- it's all about the involuntary commitment process itself).
Interestingly, Title 44 does
say, under the section about patient rights re: medication, that facilities are required to get written consent
from the client for any and all psychiatric medications (again, outside of an emergency situation).
