I've been reading The Inheritance of Shame by Peter Gajdics where he files a complaint against his unethical psychiatrist who'd created a therapeutic cult and tried "conversion therapy" on him.

The complaint was "investigated" and the clear psychological harm done to him was dismissed. Of course during the investigation, Peter was painted as severely mentally ill. Even his collapse caused by medication overdose (his psychiatrist had him taking near lethal doses) was used to paint him as unstable.

"Informed Consent" forms were supposedly signed for things such as ketamine infusions, but he was so drugged up as to not be able to think clearly, so dependent on the psychiatrist who had induced extreme dependency that he would have signed anything.

And the complaint resulted in a mere slap on the wrist: a "review" of the psychiatrist's practice. He was still able to practice and accept patients. Among the numerous patients who worked for him for free on various tasks like cooking his meals and writing for him, he also married a patient cum "employee".

In the law suit after the complaint, the most intimate details of Peter's therapy were used to discredit him and paint him as a psychotic, delusional person with severe borderline personality disorder. His traumas were all dug up and things the psychiatrist had done were given little weight. He ended up having to settle out of court.

Peter emerged with clear post traumatic reactions and while recovered now, undoubtedly went through a lot and was unable to get justice.
