Relevant to whether or not a Court may feel it was misled by mistakes made by counsel for either side what Lord Denning said in Doyle v Olby Ltd  2 All ER 119, 121 was:
“We never allow a client to suffer for the mistake of his counsel if we can possibly help it. We will always seek to rectify it as far as we can. We will correct it whenever we are able to do so without injustice to the other side. Sometimes the error has seriously affected the course of the evidence, in which case we can best order a new trial."
