Experts are more likely to have their evidence accepted in court if it is specific to the case, say experts at Edward Drummond, the executive search company. Dan Watts, director at Edward Drummond, said: 'We’re finding that the old method of working out a claimant’s potential compensation is open to challenge because it is not robust enough in terms of the amount of research carried out. Simply referring to aggregated data from National Statistics or other salary surveys is often not enough to persuade a judge to accept your evidence. The courts are only going to allow an expert’s testimony if they can prove that they are going to add real value to a case by conducting thorough, and accurate research, including interviewing people in similar careers.'
