Nigel has been an expert witness since 1995, applying his practical experience in odour and dust assessments and control to a range of commercial disputes and planning, civil appeals, nuisance claims and criminal proceedings. Nigel has reviewed evidence and written clear and well-reasoned expert reports in accordance with Criminal and Civil Procedure Rules.

Nigel has acted a Joint Expert to the Court on several matters including management and maintenance of abatement plant, and on operational practices linked to emission generation.

His expert witness experience includes provision of expertise on various matters in relation to controversial expansion plans and impact of emissions. Several cases have involved analysis of evidence in relation to breaches of permit conditions relating to odour and breaches of abatement notices.  

Nigel has also given evidence in Court under cross examination on several occasions where his evidence has been demonstrated to be robust under intense scrutiny.
