James Levy considers when courts will allow parties to change experts
In litigation cases, the expert’s overriding duty is to the court and not to the party who either instructs or pays him. As such, situations can arise when experts who have written a supportive report decide that the other side has a valid argument and that they are no longer sure of the merits of your client’s case. This was the position in Stallwood v David [2006] EWHC 2600 (QB), [2006] All ER (D) 286 (Oct).
While the overriding objective requires the court to deal with cases justly, the court has held that it would be wrong to have a total bar on a party being allowed to replace its expert. Generally, however, the court will not allow a party to change its expert simply because the expert no longer fully supports its case. Furthermore, the Civil Procedure Rules (CPR) acknowledge that experts may, as a result of their discussion with the other side’s expert, change or modify their opinion.
