Expert Witness

In cases where the planning application is refused, the applicant may go to appeal and the case will come to a Public Inquiry.

Transport Planning
Infrastructure Design
Environmental Assessment



Where the reasons for refusal relate to one of our disciplines, we are happy to use our technical knowledge to support the appeal.


In any Public Inquiry situation, a number of expert witnesses will make their case and it is essential to a successful outcome for the client that the witness is fully conversant with the project, reasons for refusal, base data and current guidance and indeed, emerging industry knowledge.

It is also the case that members of the public will be present and will make their case. At Mayer Brown we feel that an ability to deal with the genuine concerns of this group is an important skill for a witness to possess.


At Mayer Brown we have many years of successful experience, across all our disciplines, supporting clients in an expert witness role. Once the specific reasons for refusal are published, we are able to assemble any additional data required to further enforce the original works. Where the work was undertaken in-house we have the comfort knowing that methodologies and conclusions are robust and will stand the scrutiny of a Public Inquiry.

On occasion we are called upon the support the work of another consultant, or the councils refusal of an application. In these circumstances and with full access to the original data, we are able to advise on the best case strategy to ensure successful outcomes.
