In this case, expert tampering may not be an issue. But experts may often face pressure to amend their reports and this can present an ethical dilemma.
A client attorney may have an “answer” or prepared defense that he or she is hoping the expert opinion will support. However, it is important for an expert to maintain independence and render an opinion without influence from the client. The expert’s testimony also has to stand up to cross examination in a trial or deposition, so the expert is obligated to render an independent opinion based on his or her expertise, regardless of the client’s trial strategy.
So, what happens when the hired expert reaches a different conclusion than the client had hoped for when hiring him/her?
Often, this means more work needs to be done. If the attorney’s theory does not hold up with his own expert, it most likely will not hold up in court. Modifying trial strategy may seem like a daunting task, especially if the trial date is looming.
Additional research or obtaining corroborating expert opinions can be costly and time consuming. In an ideal situation, information provided by the expert may lead to a minor re-tweaking of trial strategy or a subtle difference in approach only.
