Expert Witness

Our HSE background means that you can rely on our appropriate technical knowledge, experience and qualifications to enable us to act as scientific expert witnesses in cases relating to a broad range of occupational health issues.

We have provided expert witness evidence for civil litigation acting for claimants and defendants, and this experience combined with good communications skills means that WES can deliver an objective and competent expert witness service. WES has also acted as expert witnesses in relation to criminal prosecutions

We specialise in occupational disease cases, poor asbestos surveying, uncontrolled disturbance of asbestos and asbestos contamination.

Recent examples of cases include.

1) Tracey has acted as an expert witness in a case of poor surveying, where several hundred buildings were surveyed but ACMs were routinely missed. Tracey was able to show the significance of the missed ACMs (i.e. number and type) in the context of current legislation, guidance and good practice.

2) Martin acted as an expert for a school that suffered extensive contamination following building works; investigating and demonstrating the extent and significance of the contamination (Briggs & Forrester Electrical Ltd v Southfield School for Girls).

3) Tracey provided expert advice in relation to a case where a significant amount of asbestos insulating board was missed. It was only discovered by the contractors once the demolition of the building had taken place. Tracey’s expert evidence was key in the clamaint’s successful action against the surveyor.

4) Martin was the defence expert in the successful defence of the BBC in respect of a claim of negligent exposure to asbestos causative in the development of mesothelioma. The claimant was employed as a Technical Assistant with BBC towards the end of the 1960s. Martin’s report was able to show that, although asbestos containing materials were present in the claimant’s place of work, there was no evidence that any exposure, as result of disturbance, caused any significant contribution to his lifetime risk.

5) Martin Stear was the principal asbestos expert instructed on behalf of Marks & Spencer in HSE v Marks & Spencer PLC and Others (2011).

6) Martin Stear was instructed on behalf of the Defendant in Williams v Birmingham University

7) Further examples of cases that Martin and Tracey have been involved with can be provided on request.
