“8.a. The severity of the injury cannot show whether there was a short, sharp force applied or a sustained traction. The severity of the injury can, however, imply that there was a higher peak force, i.e. if it is a very severe grade III or IV injury then it is likely that there was a higher peak force applied across the brachial plexus than with a less severe injury as in this case. It is not, however, possible in either case to know whether there was a short, sharp traction or sustained traction.” 8.b. It is not possible to know whether the baby’s head was pulled towards the floor on the basis of the injury sustained. This is, however, very important. It is now established that it is safer to pull on the baby’s head axially i.e. in the line of the baby’s spine rather than applying downward traction which is now avoided. The experts understand that in 1995 that was not so clearly understood.”
“This term has never been satisfactorily defined. Difficulty with the shoulders precedes shoulder dystocia. In the mechanism of vaginal delivery the head may be delivered at the end of a contraction. The shoulders under these circumstances are delivered with the next contraction. Failure to achieve this constitutes shoulder dystocia”
“There is no universally accepted definition of shoulder dystocia, which partly accounts for the different reported incidences between 0.23% and 1.1% of vaginal vertex deliveries …”
“Very few of our mechanical problems in obstetrics require emergency treatment. Difficulty in the delivery of shoulders, however, usually comes as a complete surprise. We have no warning, a real emergency exists, and the minutes we have in which to make a safe delivery usually pass much faster than expert help can arrive”
“Excessive rotation or traction must not be used as it is easy to fracture the cervical vertebrae or tear the brachial plexus and leave the child with a permanent Erb’s palsy”
“if any of the above manoeuvres succeed, one can usually proceed with the delivery, using moderate traction and pressure …”
“Whatever may be the objections to making traction upon the neck of the child – and there are many – there is no doubt that as a first step it is safe and prudent to begin by making very gentle traction on the delivered head, drawing it gently backwards without forced rotation and without excessive angulation, at the same exhorting the conscious patient to bear down. This is essentially a diagnostic procedure…. It is important to make the traction smooth and continuous and to avoid the application of sudden jerks. The duration of tractive effort should rarely exceed 4 – 5 seconds. One effort is enough. If it fails, the attempt at delivery should be abandoned in favour of other methods”
“95. In recent years there have been a number of first instance judgments which have helpfully crystallised and advanced learning in respect of the approach to evidence. Three decisions in particular require citation. These are: • Gestmin SGPS SA v Credit Suisse (UK) Limited[2013] EWHC 3560 (Comm) • Lachaux v Lachaux[2017] EWHC 385 • Carmarthenshire County Council v Y[2017] 4 WLR 136 96 Rather than cite the relevant paragraphs from these judgments in full, I shall attempt to summarise the most important points: i) Gestmin: • We believe memories to be more faithful than they are. Two common errors are to suppose (1) that the stronger and more vivid the recollection, the more likely it is to be accurate; (2) the more confident another person is in their recollection, the more likely it is to be accurate. • Memories are fluid and malleable, being constantly rewritten whenever they are retrieved. This is even true of "flash bulb" memories (a misleading term), i.e. memories of experiencing or learning of a particularly shocking or traumatic event. • Events can come to be recalled as memories which did not happen at all or which happened to somebody else. • The process of civil litigation itself subjects the memories of witnesses to powerful biases. • Considerable interference with memory is introduced in civil litigation by the procedure of preparing for trial. Statements are often taken a long time after relevant events and drafted by a lawyer who is conscious of the significance for the issues in the case of what the witness does or does not say. • The best approach from a judge is to base factual findings on inferences drawn from documentary evidence and known or probable facts. "This does not mean that oral testimony serves no useful purpose… But its value lies largely… in the opportunity which cross-examination affords to subject the documentary record to critical scrutiny and to gauge the personality, motivations and working practices of a witness, rather than in testimony of what the witness recalls of particular conversations and events. Above all, it is important to avoid the fallacy of supposing that, because a witness has confidence in his or her recollection and is honest, evidence based on that recollection provides any reliable guide to the truth". ii) Lachaux : • Mostyn J cited extensively from Gestminand referred to two passages in earlier authorities. I extract from those citations, and from Mostyn J's judgment, the following: • "Witnesses, especially those who are emotional, who think they are morally in the right, tend very easily and unconsciously to conjure up a legal right that did not exist. It is a truism, often used in accident cases, that with every day that passes the memory becomes fainter and the imagination becomes more active. For that reason, a witness, however honest, rarely persuades a judge that his present recollection is preferable to that which was taken down in writing immediately after the incident occurred. Therefore, contemporary documents are always of the utmost importance…" • "…I have found it essential in cases of fraud, when considering the credibility of witnesses, always to test their veracity by reference to the objective fact proved independently of their testimony, in particular by reference to the documents in the case, and also to pay particular regard to their motives and to the overall probabilities…" • Mostyn J said of the latter quotation, "these wise words are surely of general application and are not confined to fraud cases… it is certainly often difficult to tell whether a witness is telling the truth and I agree with the view of Bingham J that the demeanour of a witness is not a reliable pointer to his or her honesty." iii) Carmarthenshire County Council: • The general rule is that oral evidence given under cross-examination is the gold standard because it reflects the long-established common law consensus that the best way of assessing the reliability of evidence is by confronting the witness. • However, oral evidence under cross-examination is far from the be all and end all of forensic proof. Referring to paragraph 22 of Gestmin, Mostyn J said: "…this approach applies equally to all fact-finding exercises, especially where the facts in issue are in the distant past. This approach does not dilute the importance that the law places on crossexamination as a vital component of due process, but it does place it in its correct context." 97. Of course, each case must depend on its facts and (a) this is not a commercial case and (b) a central question is whether the core allegations happened at all, as well as the manner of the happening of an event and all the other material matters. Nevertheless, they are important as a helpful general guide to evaluating oral evidence and the accuracy/reliability of memory.”
“It wasn’t the same sort of pulling. It was a gentler pulling. Nothing like the farmyard scene”
“The anterior shoulder was delivered with the aid of suprapubic pressure and generous episiotomy. Moderate traction was required to deliver the shoulder and the body”
“Wisniewski is not authority for the proposition that there is an obligation to draw an adverse inference where the four principles are engaged. As the first principle adequately makes plain, there is a discretion i.e. “the court is entitled [emphasis added] to draw adverse inferences”.”
“Similarly, given that Ms Piper has no recollection of the incident and was reluctant to be involved, that again seems to me to be a good reason for the defendants not calling her to give evidence. Whilst it is true that the defendants called Mr Lee to give evidence even though he had no independent recollection of the incident, it does not follow that the defendants should be reasonably required to call evidence from a former employee who can give no independent account of what occurred. In short, I find that there were proper reasons and credible explanations as to why the defendants did not call the midwives and that therefore it would not be right to draw any adverse inference.”
“The Defendant has permission to serve the witness summary as sufficient evidence in the matter of the witness evidence of Dr Stephen Dobbs, consultant obstetrician and gynaecologist.”
“If positioning and an adequate episiotomy does not allow sufficient rotation and downward traction to be made, even with assistance from above….”
