Our legal system relies on experts to assist the Court in ensuring justice. Experts play a very important role. However, according to a recent judgment, there is a worrying trend of experts failing to comply with their duties and this case is a helpful reminder of how things can go wrong1.
The failures concerned two requirements of the Practice Direction to the Civil Procedure Rules (CPR) Part 35:
2.1 Expert evidence should be the independent product of the expert uninfluenced by the pressures of litigation.
2.2 Experts should assist the court by providing objective, unbiased opinions on matters within their expertise, and should not assume the role of an advocate.
This was a professional negligence claim, with the claimant seeking damages against consulting engineers. The claim concerned the design of foundations for two blocks of housing to be built on Sussex clay, a design which was found to be negligent. The claim by one claimant failed and the claim by the other succeeded, but only to the tune of £2,000 and not £3.7 million. Since the defendants' offers to settle the claims, first for £50,000 and then for £110,000, were rejected, the claimants were ordered to pay the defendants' costs.
The defendants sought to recover costs on the indemnity basis, rather than the less generous standard basis. One of the grounds they put forward was the conduct of one of the claimants' experts, Mr Hughes. In fact, while the judge thought that the expert's approach to his task "left much to be desired", he did not award indemnity costs. He nevertheless cautioned that, "Parties to litigation who rely upon expert evidence that fails to comply with the rules should not be encouraged by my finding" and went on to identify the "worrying trend".
In his judgment in the substantive claim2, the judge had made several criticisms of Mr Hughes. They read as a cautionary tale of how not to give evidence.
There are important lessons for expert witnesses here on the importance of independence and objectivity. As an expert witness, your role is to assist the Court on matters within your expertise.
Bear in mind that, at trial, your evidence will be scrutinised. Cross-examination is often a very effective way of exposing frailties in evidence. Reading publicly available criticisms of your conduct will be a very uncomfortable experience. So, it's important that you always act with impartiality in expert witness work.
