Using an Expert Witness in Legionella Cases

Using an expert witness in Legionella casesIn this post we look at the use of expert witnesses in cases involving man-made water systems, the control of Legionella bacteria and prevention of Legionnaires’ disease.

Expert witnesses aren’t used in all court cases, but they can be extremely useful in cases where an additional level of expert knowledge is required. In some instances, the evidence they give can help laypeople involved understand the facts of the case in far more detail than would otherwise be possible.

Legionnaires’ disease experts

In our previous post, we discussed the role of an expert witness in cases involving Legionnaires’ disease and highlighted the fact they will be knowledgeable in one or other related subjects. Their job may have brought them the knowledge required, they may have conducted extensive research in to the subject, or they may have had extensive training in the area. This may mean they have recognised qualifications that confirm their knowledge.

How can a legionella expert witness help in cases related to Legionnaires’ disease?

Few people know much about Legionnaires’ disease beyond information they may have read or heard about in the news. While expert witnesses aren’t often required in UK court cases – usually brought by the Health and Safety Executive, Local Authorities or the Crown Prosecution Service – there may be instances where an expert would be very useful.

For instance, someone with a greater understanding of Legionella bacteria and how, where and the rate at which it can develop might be able to provide crucial information concerning a case. In the UK the Health & Safety Executive provides guidelines on how to maintain cooling towers, process water systems and other hot and cold water systems where Legionella bacteria may readily multiply. Getting further input from a legionella expert witness with relevant experience could help support a court case in this sense.

Tasks an expert witness may help with

Legionella bacteria, its growth and development and the techniques used to keep it under control can prove confusing to some. While many court cases are concluded without the need for such an expert witness, there are instances where the evidence can be better-assessed when one is available to provide expert input.

If the death of an individual from Legionnaires’ disease has occurred, an expert witness may be able to provide an expert’s view of how the Legionella bacteria was allowed to grow, whether the control measures in place were suitable – sufficient and in accordance with the law; and also comment on how the disease could have been prevented. Other examples might include evidence relating to the growth of legionella in certain situations or conditions. A lot will depend on the facts of the case and the amount of information and understanding required by those involved in the evaluation and final judgement. Such legionella expert witnesses are not always used and are not a common sight in court rooms – even though it might seem that way on television.

Expert support for legal professionals

Providing an expert witness is impartial and has the relevant knowledge and experience required for a case, they can offer significant support to legal professionals and those involved in the court process, particularly in cases that need expert support, clarification and additional knowledge.
