No matter what the court system says, your family member has rights. One of those rights is to refuse treatment for the invented disease that the fake doctor claims that your family member has.
Just ask to see the scientific evidence of that mental condition that the "doctor" claims that your loved one fell victim to.
Just remember that if there is a diagnosis that the fake doctor assessed someone with that it came from the Diagnostic and Statistical Manual of Mental Disorders.
This book is void of all science.
Being human is not a disease.
If anything, a biological issue is causing abnormal patterns of behavior.
