Common questions
How does a court-appointed expert differ from a party-instructed expert in an adversarial system?+
A party-instructed expert is retained and paid by one side, even though professional duty requires objectivity, which creates an appearance of partisanship. A court-appointed expert is selected and instructed by the court itself, reports to the court rather than to either side, and both parties typically share the cost, reducing the perception of a hired opinion.
What is the practical advantage courts cite for moving toward single joint or court-appointed experts?+
It avoids the problem of dueling experts giving contradictory opinions on the same technical question, which can leave a judge or jury with no clear basis for a technical finding, and it can reduce cost and delay compared to each side retaining and cross-examining its own expert.
