Forensic psychiatry is the interface between law and psychiatry. It involves the assessment and treatment of mentally abnormal offenders, as well as the legal aspects of psychiatry which require knowledge of the law relating to ordinary psychiatric practice, civil law and issues of criminal responsibility.
Forensic psychiatry also includes psychiatric consultation in a wide variety of legal matters (including expert witness testimony) as well as clinical work with perpetrators and victims.
While the Canadian definition of the sub-specialty is similar to that of the USA, actual practice differs because of the difference in the legal systems.
Most practitioners of forensic psychiatry have extra training. In the United States, one year fellowships are offered in this field to psychiatrists who have completed their general psychiatry training. In Britain the requirement is a three-year subspecialty training in forensic psychiatry, after the completion of general psychiatry training.
Psychiatrists are medical physicians with specialty training in the understanding, diagnosis and treatment of mental disorders. Psychologists are professionals in their own right, and may have special expertise in topics not usually studied in detail by psychiatrists.
In Britain this is called “Fitness to Plead”. Forensic psychiatrists work with courts in evaluating an individual's competency to stand trial, defenses based on mental illness or defects like the so called "insanity" defense as well as sentencing recommendations.
Forensic psychiatrists are often called to be expert witnesses in both criminal and civil proceedings. Expert witnesses give their expert opinion about a specific issue. Sometimes the expertise is sought in an effort to provide the best possible information to judges or juries, but attorneys or other parties may also request consultation.
Much of forensic psychiatry is guided by significant court rulings or laws that bear on this area. "Not guilty by reason of insanity" is one potential outcome in this type of trial. It is important to note that insanity in this instance is a legal and not a medical term.
In cases where criminal responsibility is contested there will often there will be forensic psychiatrists acting as expert witnesses for the defense as well as for the prosecution.
Forensic Scientists in the United Kingdom
In Britain most forensic psychiatrists work for the National Health Service in specialist secure units caring for mentally ill offenders. Forensic psychiatrists often also do prison inreach work, where they go into prisons and assess and treat people suspected of having mental disorders;
Forensic psychiatrists are involved in the care of prisoners, both those in jails and those in prisons, and in the care of the mentally ill and dangerous (such as those who have been found not guilty by reason of insanity).
Forensic psychiatrists may be involved with criminal matters, civil litigation (such as malpractice lawsuits), competence, lawsuits to do things (like make a will, consent to medical care, or take care of children), child custody, treating and working with mentally ill people who get in trouble with the law, helping victims of crimes or helping lawyers and judges understand the psychological aspects of their cases or appearing as expert witnesses.
