I am no expert. Please correct me if I am mistaken:

There are two concerns- 1) legal/illegal and 2) unethical:

I have found that psychiatrists having sex with patients is illegal in some states. I believe in California the first offense is a misdemeanor. Repeated acts are felonies. I know it is illegal in other states but am not certain which ones. There are some states where it is not against the law...not criminal...for a psychiatrist to have sex with a patient.

However, psychiatrists must also answer to their medical board which determined that sex with patients is medically unethical in all states and subject to discipline. The state's medical licensing board determines which psychiatrists have their medical license revoked and which psychiatrists are disciplined in other ways.

Some psychiatrists can be held criminally liable, as well as, disciplined/revoked by their medical licensing board.

In my case, the psychiatrist was arrested for having sex with three patients. Later the DAG decided not to take the case to trial due to lack of evidence. Additionally, the psychiatrist in my case was disciplined by the state medical licensing board and his medical license was revoked in two states.

The laws are not consistent at all throughout the United States. It can be quite confusing.
