Lecture by Ms Pamela N. Gray – Saturday 26th August 2006
Locals enjoy some futile fishing in the Ganges River. The total length of the river is about 2,510 km which may still be shorter than the human reasoning process involved in a sexual assault case.
The eGanges ‘River paradigm’, according to Ms Gray, has been used extensively for quality control in manufacturing processes. Indeed expert systems seem to have a wide scope for application in any process that operates within a ‘closed system’. However ‘Systems analysis’, (which is a logical foundation for the building of expert systems), becomes inherently uncertain in open system environments. Whilst manufacturing processes may involve interactions that are clearly determinable and can be readily ‘isomorphised’ into computer based expert systems, they are by nature, largely ‘closed systems’. Furthermore manufacturing processes are by and large, devoid of humanistic interactions. On the contrary human decision making processes are generally ‘open systems’ and bereft of the mathematical methodology that is characteristic of manufacturing processes and so complaisant to isomorphism.
Decision making in Law is not only an open system, the theories of jurisprudence seem to conflict with one of the important assumptions of expert systems. That is Law is not and can never be a system of easily interpreted rules. There is human discretion at many levels and jurisprudence theory tells us that eliminating this discretion can undermine the adversarial, common law quest for justice. Ms Gray recounted a court room example of a barrister, in cross-examination of an alleged victim of a sexual assault, who was able to adduce evidence that supported the defendant’s case. I wish to invite comment on how eGanges may have been able to deal with this situation to the satisfaction of the prosecution? Ms Gray’s suggestion was that it can do so quite easily. The Uniform Evidence Act is not explicit on how this should be done so I cannot imagine how any expert system can offer a quick solution.
