"(1) This rule applies where more than one party wants to introduce expert evidence. (2) The court may direct the experts to— (a) discuss the expert issues in the proceedings; and (b) prepare a statement for the court of the matters on which they agree and disagree, giving their reasons. (3) Except for that statement, the content of that discussion must not be referred to without the court’s permission. (4) A party may not introduce expert evidence without the court’s permission if the expert has not complied with a direction under this rule."
"The purpose of discussions between experts is to agree and narrow issues and in particular to identify: (a) the extent of the agreement between them; (b) the points of and short reasons for any disagreement; (c) action, if any, which may be taken to resolve any outstanding points of disagreement; and (d) any further material issues not raised and the extent to which these issues are agreed."
"After assessing the results of detailed analysis carried out Dr Miller on the stomach contents of both victims we concur that the time of death is probably AT LEAST 2 to 3 hours following ingestion of the meal although it is UNLIKELY to be much MORE than 5 to 6 hours post consumption."
"Now just then to summarise that evidence, Dr Miller's evidence is and remains that expressed in the joint signed opinion, namely that the time of death is probably at least two to three hours following ingestion of the meal. You also have her evidence that it is highly unlikely that it was less than one and a quarter hours, although she agreed that if the fish had no batter she could not discount that entirely but did not think it likely. Dr [Conlong's] opinion has fluctuated but the opinion expressed in his evidence-in-chief was that he was 95 per cent certain that the time of death was within two hours. But he also accepted that if Dr Miller's findings of fat are correct, then he still stands by the joint opinion of at least two to three hours. The defence say that Dr Miller's evidence is to be preferred. It was consistent, clear, thorough, properly explained and the result of four days of analysis. They say Dr [Conlong's] evidence was unsatisfactory, his opinion was fluctuating and uncertain, no one can say anything with 95 per cent certainty in this field and his analysis took place over only four hours. In any event, the defence say there is no reason to question Dr Miller's findings as to fat and therefore to go behind the expert's joint statement. The defence say that this is, to use their word, vital evidence. If the time of death was at least two hours after the last meal then that would not fit the defendant's window of opportunity for killing his parents. That window closes by about 1400 hours if not slightly before. On any view, they cannot have eaten their meal by 12 o'clock and it is likely to have been some time later. At the very least the defence say this creates reasonable doubt as to whether the defendant could have been the killer."
"The conviction suffered by the applicant is unsafe for the following reason. The learned judge did not properly sum up the significance of the joint expert report and without this the jury did not have adequate explanation on how they should deal with this aspect of the case. A significant explanation was required in this case as the joint expert report significantly widens the time of death and therefore makes it less likely that the applicant was able to commit the murders."
"Where there is no dispute about the findings made by an expert you would no doubt wish to give effect to them, although you are not bound to do so if you see good reason in the evidence to reject them."
