Severe Personality Disorder and the Law.

Authors Avatar by cavalier90 (student)

"Individuals with serious personality disorders are not well served by the current criminal and civil laws in the United Kingdom relating to psychiatric defences, fitness to plead and compulsory admission to hospital‟.

Critically evaluate these remarks taking account of comparative laws and human rights where relevant.

Before these remarks are evaluated critically, it is useful to understand what is meant by the use of the following terms such as serious personality disorders, psychiatric defences, fitness to plead and compulsory admission to hospital.

 The essay begins by examining the concept of personality disorder and attempts to set the parameters within which meaningful discussion can be held regarding serious personality disordered individuals and their interaction with the legal system in the United Kingdom.

Defining personality with any degree of consensus has always been difficult; it is a word used in a common parlance to cover a variety of traits, attributes and behaviours.  It is defined as “the quality or collection of qualities which makes a person a distinctive individual”[1]. A disorder of personality is defined as “a deeply ingrained and maladaptive pattern of behaviour of a specified kind that causes difficulties in forming relationships or in functioning within society”[2].  Within the realm of medicine and psychiatry in particular, two organisations have produced definitions which have been utilised widely in clinical practice.

The International Classification of Mental and Behavioural Disorders (ICD-10) defines a personality disorder as: ‘a severe disturbance in the characterological condition and behavioural tendencies of the individual, usually involving several areas of the personality, and nearly always associated with considerable personal and social disruption’.[3] It subsequently lists 9 categories of personality disorders and the relevant criteria for fulfilling each one. This includes Paranoid personality disorder, Schizoid personality disorder, Antisocial personality disorder, Borderline personality disorder, Histrionic personality disorder, Obsessive–compulsive personality disorder, Anxious (avoidant) personality disorder, Dependent personality disorder, Other specific personality disorders,  Personality disorder, unspecified and, Mixed and other personality disorders.

The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV)  defines a personality disorder as: ‘an enduring pattern of inner experience and behaviour that deviates markedly from the expectations of the individual’s culture, is pervasive and inflexible, has an onset in adolescence or early adulthood, is stable over time, and leads to distressor impairment”.[4] It groups personality disorder into three broad ‘clusters’. These are Cluster A (the ‘odd or eccentric’ types eg.paranoid, schizoid and schizotypal personality disorder), Cluster B (the ‘dramatic, emotional or erratic’ types eg. histrionic, narcissistic, antisocial and borderline personality disorders) and Cluster C (the ‘anxious and fearful’ types eg. obsessive-compulsive, avoidant and dependent personality disorders).

It is useful at this juncture to highlight that the term “serious personality disorder” is not present in either classificatory system. Therefore one has to speculate as to what this term means and how is “seriousness” determined. The natural assumption is that seriousness is reflected by a threshold of harm that must be crossed. In this discussion it is perhaps prudent to define harm as harm to oneself and harm to others and as a consequence the following personality disorders maybe deemed to be serious. They are Borderline Personality Disorder, Antisocial Personality Disorder and Paranoid Personality Disorder.

This essay primarily focuses on Antisocial Personality Disorder as well as other related entities such as Psychopathy and Dangerous and Severe Personality Disorder.

Antisocial personality disorder is defined by the Diagnostic and Statistical Manual,  as a personality disorder characterized by "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood."[5]

The World Health Organization's International Statistical Classification of Diseases defines a conceptually similar disorder to antisocial personality disorder called Dissocial personality disorder.[6]

Both the DSM and the ICD state that psychopathy are synonyms of their diagnosis. In the Mental Health Act 1983 of England and Wales, the term psychopathic disorder is employed and defined as a ‘persistent disorder or disability of mind (whether or not including significant impairment of intelligence), which results inabnormally aggressive or seriously irresponsible conduct’. [7]

In England and Wales, the law has accepted the medical view that antisocial behaviour may result from a psychological abnormality, distinct from mental illness, and that it may be appropriate to divert offenders suffering from this disorder to the mental health system for treatment rather than punishment. However, the statutory category of 'psychopathic disorder' is different from clinical classifications of the condition. In its legal use, for instance, 'psychopathic disorder' has no specific clinical meaning and is a generic term based solely on the presence of antisocial behaviour, as distinct from the range of features required for a clinical diagnosis of the syndrome.[8]

Lastly the term Dangerous and Severe Personality Disorder was introduced by the UK Government in a consultation paper entitled “Managing Dangerous People with Severe Personality Disorder” in 1999[9], which proposed how to detain and treat a small minority of mentally disordered offenders who pose a significant risk of harm to others and themselves. The condition's characteristics were not clearly defined, but it was thought to be an extreme form of antisocial personality disorder; the diagnosis commonly linked with psychopathy. This programme was introduced following a tragic killing and the subsequent conviction of Michael Stone, who was said to have a severe personality disorder and was allegedly denied access to psychiatric care.

Psychiatric defences refer to legal defences that can be employed so that an individual is not found culpable because he/she did not have a sufficient degree of mens rea. These defences include diminished responsibility, not guilty by reason of insanity, automatism and infanticide.

In English Law, the defence of diminished responsibility for murder was introduced in 1957. The Homicide Act 1957 (Section 2) states: “where a person kills or is party to a killing of another, he shall not be convicted of murder if he was suffering from such abnormality of mind (whether arising from a condition of arrested or retarded development of mind or any inherent causes or induced by disease or injury) as substantially impaired his mental responsibility for his acts and omissions in doing or being party to the killing”.[10]

The defence is only available to cases involving murder and ...
