Obviously I don't know all the details of the case but I find it troublesome that a psychiatrist would render an opinion without examining the individual who is the object of the opinion. On its face this is unethical particularly in a situation where there's so much at stake.
I'm aware that "assessment at a distance" is frequently sought, for example, reviewing clinical info in the medical record to determine if services were consistent with billing for reimbursement. This is often a question arising with Medicare and other 3rd party payers. However that's not unethical since it's quite different from providing a diagnosis or determining the qualities of a person's functioning without examining the individual.
I have no idea if the doctor's conduct had come before the state licensing board, but it appears there would be substantial reason to consider that conduct "unprofessional" given the actions of the professional societies declaring the behavior as unethical. Normally such disciplinary action carries consider weight with licensing bodies. Most likely this avenue of doing something to keep the situation from recurring has already been explored, it would be a shame if it was overlooked.
