Expert Advisor 

One alternative to engaging an Expert Witness is to engage an Expert Advisor. This might also be a cost-effective alternative. A key benefit here is that the expert’s advice including client report, remain privileged and non-disclosable. This permits the client to access the expert’s knowledge, guidance and opinion. This role may also assist in strategic planning of a case. 
 
An expert advisor can be quickly instructed without a need to wait on Legal Aid funding. They can assist in narrowing cases to focus on key issues pre-proceedings and ensure those involved in a case are provided with contemporary knowledge and opinion. Early instruction can also assist in such issues. An Expert Advisors would not be called to appear in court.

Court Appearances 

GangsGangsWhat is the difference between an Expert Advisor and Expert Witness? 
 
An EA is any person able to assist an investigation because their specialist knowledge and/ or experience allows them to give an opinion on a particular matter or provide a specialist service directly related to their expertise. EA’s are independent of the Police Service (or Solicitor) and are usually employed to interpret and present evidence as a forensic expert, as a witness, although they are not necessarily an expert witness. 
 
Expert evidence is admissible to furnish the court with information that is likely to be outside the experience and the knowledge of a judge or jury (Criminal Practice Direction V Evidence 19A Expert Evidence). 
 
An Expert Witness can provide the court with a statement of opinion on any admissible matter calling for expertise by the witness if they are qualified to give such an opinion. 
 
What makes a suitable EA will depend on the context of a particular case. An EA’s expertise and qualifications are only useful to an investigation if they are relevant to the issues in that investigation. Expertise can be demonstrated through formal, recognised qualifications or through experience. The type of expertise that is appropriate will depend on the nature of the investigation.
