Automatism, medicine and the law.

Area of Science:

• Forensic Psychiatry
• Medical Law
• Neurology

Background:

• The legal framework for automatism, distinguishing between 'sane' (external cause) and 'insane' (internal cause), conflicts with medical understanding.
• This distinction leads to disparate legal outcomes, with sane automatism resulting in acquittal and insane automatism in committal to a secure mental hospital, regardless of the act's severity.

Purpose of the Study:

• To trace the historical development of automatism law from the 1950s to the present.
• To analyze the legal and medical inconsistencies in current automatism defenses.
• To propose reforms for a more equitable legal treatment of automatism.

Main Methods:

• Review of legal precedents and medical literature concerning automatism.
• Analysis of case law involving various conditions such as epilepsy, alcohol/drug-induced states, hypoglycaemia, transient global amnesia, and hysterical automatism.
• Examination of the role of expert medical evidence in court proceedings.

Main Results:

• The current legal dichotomy between sane and insane automatism lacks a clear medical basis.
• Specific conditions like hypoglycaemia present legal challenges, with outcomes differing based on whether the cause is deemed internal or external.
• The mandatory committal following a verdict of 'not guilty by reason of insane automatism' is inappropriate for non-violent offenses.

Conclusions:

• The existing law on automatism is unsatisfactory due to its medical inaccuracies and rigid sentencing.
• There is a need for judicial discretion in sentencing for automatism defenses, particularly in cases of non-violent crimes.
• Reforms are suggested to align legal practice with medical understanding and ensure fairer outcomes.
