STRICTLY EMBARGOED UNTIL 10.30 A.M. ON TUESDAY 28TH JANUARY 2003 Clare Montgomery QC's skeleton argument for the Appeal hearing. This is a plain text copy of the original document, which can be found at http://www.sallyclark.org.uk/ IN THE COURT OF APPEAL (CRIMINAL DIVISION) 2002/3824/Y3 IN THE MATTER OF A REFERENCE BY THE CRIMINAL CASES REVIEW COMMISSION THE QUEEN v. SALLY CLARK Appellant _____________________________ SKELETON ARGUMENT ON BEHALF OF SALLY CLARK _____________________________ For nearly three years after the death of Harry Clark, his mother Sally Clark, her lawyers and their medical advisers believed that there was not any evidence of infection or any possible natural explanation of his death. The cause of his death was mysterious and, in the language of the medical profession, "unascertained". At the end of 2000 it emerged, for the first time, that there was clear evidence of an infection with staphylococcus aureus that had spread as far as Harry's cerebral spinal fluid (CSF). This fluid should be sterile in a healthy child, protected from harmful substances in the blood by the blood brain barrier. The evidence of this infection had been known to the prosecution pathologist, Dr Williams, since February 1998. He had kept the results secret from Sally Clark and her advisers. This is a clear case of non disclosure by the prosecution. This non disclosure has caused a serious miscarriage of justice. The microbiological test results on Harry Clark demonstrate that, in all likelihood, he died suddenly, in reaction to the staphylococcus aureus bacteria with which his stomach, lungs and CSF were riddled. It requires no degree of expertise to realise that the test results should have been revealed by Dr Williams and not kept secret. It is obvious that, if the results been made known at trial, Sally Clark would not have been convicted of murdering Harry or his dead brother, Christopher. It is a matter of regret that the prosecution has failed to accept that there has been any material non disclosure in this case. Instead an attempt has been made to minimise the importance of the microbiological test results. This has wholly failed. It is plain even from the statements made by the prosecution expert witnesses, that the results were material, in the sense described in R v. Judith Ward[1], in that they might arguably have assisted the defence at trial. Each of the prosecution experts has conceded that it is possible that Harry died of acute staphylococcal infection. The area of disagreement between the prosecution and defence experts is the degree of likelihood to be attached to that possibility. Dr Keeling's conclusion is; "The concept of an infectious cause of death was not considered by any of the experts at the original trial. Now that the concept of infection has been introduced it is important to appreciate that the case for infection is being made on the basis of positive cultures. Positive cultures alone are not sufficient evidence of the presence of disease; they can be artefactual as the result of contamination.[2]" (Emphasis added). Dr Klein's opinion is that; "While there is no doubt that the sequence of events as described [by Dr Morris of an infection and toxic reaction causing bleeding] could occur in an infant of Harry's age it would be exceedingly rare in an otherwise healthy individual.[3] " Dr Wilson concludes that, in his view, the staphylococcus must have spread in the blood stream before Harry's death. The absence of toxins does not exclude the organism being contributory to death. The white cell response in the CSF is probably related to a bleed but the presence of early meningitis is not excluded. "S. aureus and/or its toxin is suspected to be a cause of SIDS but the mechanism has not been elucidated. It can cause petechial haemorrhages secondary to circulatory failure and toxin release.[4]" An attempt has also been made by the prosecution, in the alternative, to say that the biochemical tests were so obviously flagged that they were effectively disclosed and it is the fault of the defence that the results were not discovered. Finally and bizarrely it is suggested that the results were known to the defence but were discounted or disregarded because they were irrelevant. The last two suggestions may be rapidly disposed of. In his second affidavit, Michael Mackay has confirmed that none of the defence lawyers were made aware of the results[5]. This mirrors the position of the CPS which asserts that none of the prosecution lawyers knew of the results[6]. The assertion by the CPS is accepted, subject to the caveat that any prosecution lawyer who inspected file 89 at court (in which the results were probably stored[7]) may have become aware of the results and should then have disclosed them. The prosecution skeleton disingenuously suggests that the test results "were always available for inspection"[8]. This is not true. The results may, as it transpires, have been available for inspection by the prosecution in police file 89. However that was not a file that was ever listed in the prosecution list of used and unused material. It was not "available" to be inspected by the defence lawyers in any meaningful sense of the word. The prosecution also suggest there was disclosure because the fact of testing was revealed, even if the results were not[9]. This suggestion is wrong. Disclosure is not meant to be a game where the defence guess what may be relevant with the benefit of hints dropped by the prosecution. Unless and until the existence of positive microbiological results are made known to the defence and copies of those results are supplied or inspection invited, they cannot be said to have been disclosed. The prosecution argument appears to have overlooked the fact that the professional and legal obligation to effect disclosure by providing copies or inviting inspection has been clear for more than 20 years. The old Attorney General's Guidelines[10] required disclosure to be effected by provision of a copy, either by post, by hand, or via the police. If the unused material exceeded about 50 pages or was unsuitable for copying, the defence solicitor had to be given an opportunity to inspect it at a convenient police station or, alternatively, at the prosecuting solicitor's office. The House of Lords has held (in overturning the rule in Bryant and Dixon)[11] that the common law requires the physical disclosure of police witness statements by the provision of a copy. The Criminal Procedure and Investigations Act 1998 (the CPIA) requires disclosure to be effected by copying the information to the defendant or, if that is not practicable or desirable, allowing the defendant to inspect it[12]. The decision in R. v. X Justices ex parte J[13] has made it clear that there is in all criminal cases a strong presumption in favour of the provision to the defence in good time of copies of all copiable exhibits. It is for the prosecution to displace that presumption. No factors justifying the displacement of that presumption have been identified. So far as the defence medical experts are concerned, all bar Professor Emery (who died before the results were disclosed) have been contacted. Each has confirmed that results were not disclosed by Dr Williams or seen by them in the course of the case. Professor Berry has said in terms he was never told about the results. Indeed he seems to have been misled into believing that there was a negative result in relation to the microbiology tests performed on Harry. In his report dated 3.9.99, he stated that neither Harry nor Christopher "showed any symptoms in life, nor was the mode of their death compatible with infection. All tests for infection were negative with the exception of the unremarkable finding of Staph. aureus in the respiratory tract of Christopher." Contrary to the suggestion by the prosecution that his opinion would have been unaffected by knowledge of the results[14], Professor Berry has made it clear that the results were "very unusual" and would have had a significant impact on his opinion as to the cause of Harry's death[15]. Dr Rushton is equally confident that he was not made aware of the results at the time of the trial. Had he been he; "would certainly have investigated the significance of the isolation of the staphylococcus by consulting my microbiological colleagues". He has concluded on the basis of the reports now available from the defence micro biologists that the death of Harry was due to staphylococcal infection[16]. Professor Luthert has also confirmed that he was not aware of the results. He described the situation on non disclosure to Mike Mackey as "blood chilling"[17]. He has also stated that he would have no difficulty in reconciling the episcleral haemorrhages at the back of Harry Clark's eyes with death arising from septicaemia. Professor Whitwell has confirmed that she was not told of the results[18]. She understood Dr Williams assertion to the effect that there was no evidence of disease to be a confirmation that the microbiological results were negative. Each of these experts has also confirmed that they relied upon the prosecution doctors to disclose all relevant results. This is obviously the proper approach, both as a matter of law and as a matter of common sense. The only contrary suggestion comes from Dr Keeling who herself failed to seek the results. She excuses that omission by reference to her late involvement[19]. This is not an issue that needs to be resolved for the reasons set out in the Defence Note of November 2002. If this is not a case of prosecution non disclosure, it is a fresh evidence case in which relevant and credible fresh evidence is now available. Professor David (the court appointed expert who gave evidence for the defence with the leave of the family court judge) has been contacted by prosecution counsel. Following that contact prosecuting counsel has suggested that the results may have been disclosed to Professor David because "it is still not known for sure whether the microbiology results were in fact in the papers supplied to Professor David[20]." Given Professor David's response in his letter dated 6th December 2002[21] this seems a far fetched basis on which to claim the tests results were disclosed. Professor David has been explicitly dismissive of the prosecution suggestion that the results may have been disclosed to him, but ignored, because he regarded them as irrelevant. His letter states: "What is so extraordinary is that these results were obviously of special interest to the pathology department to the extent that the samples were actually sent away to the headquarters of the public health laboratory service for further testing and yet, despite this step being taken, none of the results were disclosed. The PHLS in Colindale is the national reference laboratory for microbiology and I am at a loss to understand how all these results and laboratory data did not come to be passed into the care proceedings papers. There is no doubt that had these results been available, I would have referred to them in my report and I would have investigated their possible significance further not only in relation to the death of Harry but also the death of Christopher." Non disclosure Unfortunately this case demonstrates that the lessons that should have been learned, as a result of the decision of the Court of Appeal in Ward[22], have not been. The duties of the prosecution and of the forensic experts instructed by the Crown were spelt out in clear and uncompromising terms in Ward. The scope of that duty has not been affected by the coming into force of the CPIA since the CPIA does not affect the common law duty of disclosure of expert witnesses, see Archbold 10-68. The Court in Ward dealt with the critical importance of ensuring that there is a proper understanding of the nature and scope of the prosecution's duty of disclosure in relation to expert scientific witnesses. The prosecution barrister in that case had suggested that the problem was solved by the Crown Court (Advance Notice of Expert Evidence) Rules 1987 that enable the legal representatives of a defendant in a Crown Court criminal case to require the prosecution by notice in writing to provide in respect of scientific evidence a copy of (or an opportunity to inspect) "the record of any observation, test, calculation or other procedure on which (any) finding or opinion is based." The Court observed: "The new rules are helpful. But it is a misconception to regard them as exhaustive: they do not in any way supplant or detract from the prosecution's general duty of disclosure in respect of scientific evidence. That duty exists irrespective of any request by the defence. It is also not limited to documentation on which the opinion or findings of an expert is based. It extends to anything which may arguably assist the defence. It is therefore wider in scope than the rule. Moreover, it is a positive duty, which in the context of scientific evidence obliges the prosecution to make full and proper enquiries from forensic scientists in order to ascertain whether there is discoverable material. Given the undoubted inequality as between prosecution and defence in access to forensic scientists, we regard it as of paramount importance that the common law duty of disclosure, as we have explained it, should be appreciated by those who prosecute and defend in criminal cases. And, if difficulties arise in a particular case, the court must be the final judge.[23]" Even for a layman it should have been readily apparent that the microbiology tests results might raise two or more medical issues in connection with the death of Harry Clark. The first obvious issue was whether the results indicated staphylococcus aureus infection. The second issue was, assuming that there was an infection, what effect might that have had on Harry's condition. In Keane[24] the Lord Chief Justice made it clear that the documents that must be disclosed as 'material' are those that can be seen; "on a sensible appraisal by the prosecution: (1) to be relevant or possibly relevant to an issue in the case; (2) to raise or possibly raise a new issue whose existence is not apparent from the evidence the prosecution proposes to use; (3) to hold out a real (as opposed to fanciful) prospect of providing a lead on evidence which goes to (1) or (2).[25]" Any qualified medical practitioner or prosecutor who was shown the microbiology results ought to have appreciated that they might possibly raise issues in the case of Sally Clark, whose existence would not be apparent from the evidence the prosecution proposed to use. Good faith? It is submitted that the non disclosure must have been deliberate, since it is to be assumed that the prosecution asked appropriate questions to ascertain whether there was discoverable material in Harry's case. Questions such as: "Are there any test results relating to Harry Clark that have not already been disclosed?" must have been posed. The prosecution must have been told, wrongly, that there were not. This appears to be the explanation for the assurance given by the solicitor to the Police Authority (following discussions with the CPS and DI Gardiner) in April 1999 that there were no further autopsy reports other than those already disclosed[26]. It is appears that responsibility for the deliberate non disclosure lies with Dr Williams. He was the sole named recipient of Dr Wills' reports. He is most likely to have provided the false or misleading information that the CPS and Police Authority solicitor relied upon. Dr Williams' explanation for his failure to disclose the reports is wholly unsatisfactory. His claim to the meeting of experts that there was no evidence of infection in Harry's case[27] was, on its face, untrue. His present position is equally incredible[28]. On one view the question of Dr Williams' credibility may be something of a side issue for the reasons identified in the Defence Note of November 2002. If the Court concludes that the microbiology results were not disclosed and that the expert opinions now obtained, commenting on the relevance of the results, amount to credible fresh evidence going to a relevant issue in the trial, then the appeal should be allowed. However it is submitted that the fact of a deliberate non disclosure will impact on Dr Williams' credibility, competence and claimed impartiality. This is of significance since the majority of the critical points in the prosecution case depend upon disputed and inadequately documented 'findings' by Dr Williams. Thus the case on Christopher in relation to the 'nick' in the frenulum and the presence of abrasions or bruises depends entirely on Dr Williams' evidence. Without that evidence, the only relevant medical evidence relating to Christopher that was properly recorded and capable of being independently investigated were the slides of Christopher's lungs showing bleeding and haemosiderin and the test results relating to Christopher's blood chemistry. No expert has suggested that the slides of the lungs are capable of establishing a case of murder. At its highest, the presence of bleeding merely requires close attention[29]. In the absence of any other material it is not does not establish the cause of death. Dr Williams' credibility is also of acute significance in Harry's case. Much turns on Dr Williams' denial of the allegation that many of his findings were artefactual, caused by his faulty post mortem technique. For example, in the original police investigation, great significance was attached to his finding of haemorrhages in the eye. In the course of discussions between the experts it became apparent that Dr Williams could not tell the difference between the choroid and the retina. In the event, by the time of trial it was accepted that there were no relevant retinal haemorrhages. However, both at trial and on appeal, attention was given to the 'finding' by Dr Williams of scleral haemorrhages. The defence case is that they are artefactual. Dr Williams' competence and credibility is therefore directly in issue on this point. Similar issues arise in relation to Dr Williams 'finding' of bleeding and swelling in connection with Harry's spinal cord. The claimed swelling was not detectable in the sections taken by Dr Williams. The bleeding was likely to be post mortem in origin, in the view of the defence experts. The suggestions that there was a dislocation between the cartilage and the bone of Harry's right second rib and a callus formation on his rib are similarly dependent on the reliability of Dr Williams' observation. There was no evidence of fracture on the X ray and no adequate attempt was made to document the 'finding', either photographically or histologically. The existence of a fracture or dislocation is also quite inconsistent with Harry's observed well being at all times prior to his death. Dr Williams' claim that the biochemistry results were irrelevant does not stand up to scrutiny. The detailed forensic attention that has been paid to the results for the purposes of this appeal underlines the fact that it is highly unlikely that a skilled and conscientious pathologist would have ignored the results and treated them as unworthy of mention. For this reason alone, the defence does not accept Dr Williams' explanation for not referring to the results in his reports, in his discussion with defence experts and in his evidence at trial. Prof Berry describes the results as "very unusual"[30]. Dr Morris describes them "highly significant[31]". Dr Walters says they are "most unusual"[32] and adds that to find staphylococcus aureus as a contaminant with the presence of polymorphs in two sites would be "remarkable"[33]. Prof Fleming confirms this. Staphylococcus aureus "is not a common organism to be isolated from multiple deep sites at post mortem and is very rarely isolated from the CSF"[34]. Even Dr Wills suggested in his original letter to Dr Williams that: "It is somewhat unusual to find a contaminating organism so widely spread and it may be that there was a transient or terminal bacteraemia [The presence of viable bacteria circulating in the bloodstream]."[35]. For the prosecution, Dr Keeling accepts that "CESDI[36] study findings (no SA cultured from CSF) indicate that it is an unusual occurrence and its significance should be considered most carefully. Sonnabend et al 1985 accept a pure culture of an organism in the CSF is evidence of pathogenicity [the ability of a parasite to inflict damage on the host]."[37] The standard protocol for pathologists in the investigation of sudden unexpected deaths[38] requires the "bacteriological examination of bloods, cerebrospinal fluid and lung to rule out septicaemia, meningitis and bacterial lung infection respectively". The standard work on the Principle and Practice of Infectious Diseases[39] emphasises the role played in the diagnosis of bacterial meningitis by a CSF examination. For Dr Williams to dismiss the reported finding of staphylococcus aureus in the cerebrospinal fluid (CSF) coupled with the presence of white blood cells, polymorphs, lowered glucose and a raised protein level without any discussion or disclosure is extraordinary. The failure by Dr Williams to refer to the test results is also a clear departure from best practice. There is evidence that, in the context of a police investigation or a coroner's inquiry, a pathologist should record the outcome of all results, whether positive or negative, in his report[40]. In the absence of such action by the pathologist there appears to be no mechanism for informing the authorities, such as the police, the coroner, and the CPS of the results[41]. As Dr Walters observed "an autopsy report that does not include the results of supplementary tests is an incomplete record of the examination, capable of misleading anyone who consults it in the future."[42] Dr Keeling, for the prosecution, agrees with this. "Reports of all investigations done outwith the pathology department are reported in full including the accession number to facilitate any discussions at a later date.[43]" The best practice is in fact exemplified in Dr Williams' own report to the coroner where he reports his negative findings. Features that were said by Dr Williams to be irrelevant on analysis (such as a mark on Harry's cheek), were identified and carefully explained in his report. Furthermore, even if Dr Williams may claim that he was entitled to regard some of the results obtained as contamination; it is plain that some of the results were not. The transient bacteraemia suggested by Dr Wills and the identical phage typing suggest that there was staphylococcus aureus in Harry's airways. This finding should have been reported, just as it was in the case of Christopher, even if it is then dismissed as being unexceptional. If, as Professor Green claims[44], Dr Williams told him about the results in Harry's case (although Dr Williams does not claim to have done so), that can only serve to confirm the proposition that the results should have been disclosed in order that they could be taken into account by others. There is no excuse for Dr Williams not providing the same information to Professor Emery and Dr Rushton when they performed the second post mortem. The only purpose in reporting the results to Professor Green can have been because they were potentially relevant to anyone providing a second opinion. They would have been equally relevant to Professor Emery and Dr Rushton. In fact Professor Green's note does not support either Dr Williams' claim that the finding of staphylococcus was irrelevant, or Professor Green's own memory that Harry's results were discussed. The prosecution quotation from the note in its skeleton argument is incomplete and misleading[45]. The note records[46]: "Christopher Clark was brought in dead to Macclesfield hospital shortly after 9.30pm. He was alone with his mother and was allegedly being nursed in his bouncy chair. She had breast fed him a few hours previously. Dr Williams was concerned that the child had various minor bruises and abrasions (although the post-mortem photographs are of very poor quality). The child also had a torn frenulum, but as resuscitation had been attempted, Dr Williams felt he should give the child "the benefit of the doubt". Staphylococcus aureus was grown from various swabs, and therefore although the histology showed no convincing signs of infection, this was written off as a cot death. . He [Dr Williams] had made no comment on the histology of the lungs of Christopher Richard Clark except to note the presence of "focal inflammation". Again specimens from this child grew a staphylococcus." (Underlined part quoted in prosecution skeleton argument and said to be a reference to Harry) The significance of the note (if it is accurate) from the point of view of the defence, is that in 1998 Dr Williams was prepared to ascribe significance to the finding of staphylococcus aureus (in Christopher), a proposition he has since been forced to ignore in his efforts to excuse his non disclosure in the case of Harry. It will be observed that the note provides no support for the proposition that the finding of staphylococcus in Harry was discussed. It strongly suggests that it was not. The note also suggests that the failure to report Harry's results was a clear departure from Dr Williams' own practice of reporting biochemistry results. It supports the possibility that the non disclosure was deliberate and motivated by partisan considerations. The partisan motives may also be evident in the fact that Dr Williams persistently failed to correct the defence experts, all of whom proceeded on the basis that there was no evidence of infection. For example Professor Berry in his report dated 3.9.99 stated that neither Harry nor Christopher "showed any symptoms in life, nor was the mode of their death compatible with infection. All tests for infection were negative with the exception of the unremarkable finding of Staph. aureus in the respiratory tract of Christopher." Even if Dr Williams did not supply this inaccurate information to Professor Berry, he must have noticed Professor Berry's error and should have corrected it. The whole trial proceeded on the basis that there was no natural explanation for non-artefactual bleeding in Harry, no evidence of natural disease and no natural explanation for his death[47]. Defence experts were repeatedly forced to concede that there was no evidence of infection or other natural causes[48]. Sally Clark was driven to accept that she could not explain how Harry died or why he might have bled. Dr Williams never volunteered the information that there was evidence of infection (even if he personally did not believe it). When the jury asked "Are there blood tests results for Harry?" Dr Williams gave a deliberately misleading answer. The degree of deliberation involved is confirmed by the fact that it is now clear from the police investigation, carried out in 2002, that Dr Williams must have consulted the files that contained toxicology, virology and microbiology[49] results for Harry before answering the question. Robin Spencer QC has devoted 16 pages of his skeleton argument[50] to an attempt to excuse and explain what was, on any view, an incomplete answer given by Dr Williams. "Q Can I turn to the blood sampling for Harry? Have you been able to make enquiries and check the records in respect of Harry? A We've looked at the records as far back as we can. . Q Was a blood sample taken from Harry at post mortem when you carried the post mortem out? A Yes, a sample is always taken at post mortem. Q Do you know what was done with that? A That was submitted for toxicological examination and some of it would have been sent for viral studies." Whilst the explanation fashioned by Mr Spencer (in the absence of evidence tested under cross examination from Dr Williams) might just be possible if, as he suggests, the question was misunderstood by Dr Williams, it is not a likely explanation. It is extraordinary that Dr Williams should choose to refer only to toxicology and viral studies when he knew that there has also been microbiological testing. All are equally remote from the topic of blood chemistry that Mr Spencer suggests lay behind the jury question and Dr Williams' answer. The non disclosure was material/Fresh evidence As the Court will appreciate from the Defence Note of November 2002, it is submitted that the success of this appeal is not dependent on the prosecution non disclosure. The appeal could be allowed on the grounds of fresh evidence alone. The evidence of the defence experts is plainly capable of belief. It would have been admissible at trial. There is a cogent explanation for the failure to call it at trial, namely that the defence did not know that there had been a positive result obtained from the microbiological testing. The only relevant issue in connection with the fresh evidence is whether the evidence may afford a ground for allowing the appeal. As the House of Lords indicated in Pendleton[51], the Court is entitled to form a view on whether the evidence give rise to a reasonable doubts about the verdict. The Court should however recognise it is at a disadvantage in seeking to relate that evidence to the rest of the evidence which the jury heard. "For these reasons it will usually be wise for the Court of Appeal, in a case of any difficulty, to test their own provisional view by asking whether the evidence, if given at the trial, might reasonably have affected the decision of the trial jury to convict. If it might, the conviction must be thought to be unsafe." There are three questions that may have to be answered in assessing materiality or the safety of the conviction. The first question is whether the results may have been caused by infection rather than contamination? The second question is what may be the effect of staphylococcal infection? The third question is the issue canvassed above, namely the impact on Dr Williams' credibility and competence of the fact of deliberate non disclosure. 1. Contamination? There is no plausible basis for assuming contamination. The finding of staphylococcus aureus in the CSF is highly unusual[52]. In studies[53] of hundreds of sudden infant deaths, there has been only 1 case in which the CSF was found to be infected with staphylococcus aureus and 7 where staphylococcus aureus was found in the blood. Since it is common and unremarkable for such infants to have staphylococcus aureus in their airways[54], it is astonishing if the mechanism of contamination favoured by Dr Keeling is possible or even likely, that staphylococcus aureus has not been found more widely in the blood and CSF of dead infants. In addition, the absence of staphylococcus aureus in the blood suggests that any contamination did not occur during resuscitation or after death. The only physical medium in which staphylococcus aureus in the airways, lungs or stomach could be transferred so as to contaminate the CSF is the blood[55]. The absence of staphylococcus aureus in the post mortem blood sample suggests that contamination did not happen at the point of death or resuscitation since there would be no mechanism for the staphylococcus aureus to disappear from the blood and yet remain in the CSF. The absence of staphylococcus aureus in the blood sample taken by A&E has no significance either way since the sample may not have been large enough[56] In any event a negative culture does not exclude infection[57]. Overall the absence of staphylococcus aureus in the blood argues strongly in favour of a infection in life that Harry's defences may have cleared from his blood but whose presence elsewhere had not be cleared and killed him. This appears to be a possibility accepted by Dr Wilson for the prosecution[58]. The fact that the finding is of a single pure organism also suggests there is no contamination. Contamination caused by intubation or resuscitation might be expected to spread a variety of organisms, not a single organism[59]. The case for contamination is undermined by the levels of red blood cells and leukocytes (white blood cells) plus polymorphs in the CSF[60]. The presence of polymorphs can only be explained by a reaction to infection or irritation in life[61]. This is conceded by Dr Keeling[62]. Dr Wills for the prosecution agrees that the presence of white blood cells indicates an inflammatory reaction.[63] Dr Wills also concedes that: "The polymorph cells [in the CSF] are suggestive of a bacterial infection,[64]" although he goes on to says that the response is too low for meningitis. Dr Wilson states that "polymorphs in the CSF do suggest a reaction to inflammation before death, as the ratio of red to white cells is not what would be expected from a simple leak of blood into the CSF.[65]" The attempt to explain the polymorphs and white blood cells by reference to a prosecution theory that Harry had been shaken and had bled into his CSF in the last 2 to 3 hours of his life does not stand up to scrutiny. Not only is the number of red cells minute (no more than a pin head of blood) and insufficient to cause irritation, but the reaction to the presence of that blood in the CSF would account for only 1 of the 80 leukocytes plus polymorphs observed[66]. Dr Wills has conceded this, albeit at a late stage[67]. The only available and plausible explanation for the remaining 79 leukocytes is the presence of the staphylococcus aureus. The blood irritation theory also provides no explanation for the presence of staphylococcus aureus and polymorphs in the stomach[68]. No one has suggested bleeding at that site or the presence of any other irritant[69]. Dr Wilson considers that this also points towards an infection during life[70]. His conclusion is "that it is not possible to exclude meningitis in addition to bleeding into the CSF". The presence of staphylococcus aureus, in life, for several hours is also supported by the presence of polymorphs[71] coupled with the raised protein levels, the reduced glucose levels[72] and the colour of the CSF. At a late stage the prosecution experts appear to have abandoned the attempt to make the microbiological facts fit the theory advanced by Mr Spencer that "Harry had been subjected to some trauma two to three hours prior to death, by shaking or otherwise .[73]." It is now suggested by the prosecution, in yet another attempt to make the facts fit a murder charge, that the microbiological results are the result of much older bleeding. This is unacceptable for a number of reasons. First it is noteworthy that the shift of ground seems to be justified by reference to the disputed finding by Dr Williams of a rib fracture and haemosiderin around Harry's cord. Second the suggested early bleeding makes no sense. It would take a considerable and significant bleed to raise the protein to 3.24gms/litre. This must have occurred at least 10 days prior to death as it would take at least that time to clear the red cells (only 230 per microlitre remained at the time of death). Any such bleed would have caused Harry to be extremely ill. This would have been obvious to all concerned and he would have required admission to hospital and intensive care. In fact at all times up to 4 hours prior to his death Harry was seen by a series of independent witnesses to be healthy and well. He exhibited no signs of distress. He was handled daily by health care workers who noticed no physical discomfort and saw no signs of injury. At that time Harry's CSF protein must have been normal and he could not have been suffering from meningitis. He cannot have suffered physical trauma. The elevated CSF protein must therefore be due to events in the last four hours of his life. If it is not a consequence of a recent bleed, the only plausible explanation is cytokine release due to staphylococcal infection. The suggestion that the turbidity of the CSF and its xanthachromatic (yellow) colour indicate bleeding has also been demonstrably destroyed[74]. So far as turbidity is concerned, the growth of staphylococcus aureus post mortem would be limited for the reasons explained by Professor Blackwell[75]. The Avon study confirms this. "There is no correlation between the length of time taken before post mortem and the finding of bacterial samples." The CESDI study also confirmed this. "There was no clear relationship between mixed growth in blood samples and increasing post-mortem intervals." The contrary view expressed by Dr Klein is based on little more than guess work[76]. So far as colouration is concerned, the prosecution case depends upon the proposition that bilirubin may appear within 4 hours of a bleed into the CSF. In fact as Dr Walters has pointed out by reference to the standard work on cerebrospinal fluid[77], bilirubin does not usually appear until 10 hours or more after the episode of bleeding. In the first 4 hours after a bleed, the CSF would be coloured pink by the process of lysis. Furthermore the presence of bilirubin would initially appear in combination with haemoglobin and give an orange colouration. Dr Walters' calculations have proved that it is impossible to ascribe the colour (if correctly observed) of Harry's CSF to the presence of bilirubin related to bleeding[78]. It may be related to the increase in the protein level[79]. It may more probably be related to the length of time that elapsed before the post mortem was performed[80]. Any prosecution proposition that propounds that Harry must have bled into his CSF as the result of trauma inflicted by Sally Clark is also inconsistent with two other observations. First it is impossible to postulate a form of trauma that would cause bleeding at the site identified by Dr Williams without causing damage to other areas of the spine. Second there is no other evidence of shaking such as would be present in a case of shaken baby syndrome. If bleeding was present in the CSF and occurred in life it is more likely to be related to haemorrhage caused by staphylococcus aureus toxins. It appears most likely however that the bleeding was post mortem and caused by contamination. This proposition is supported by the absence of any signs of haemoglobin discolouration. 2. The effect of staphylococcal infection? The second question which the court must address in connection with the issue of materiality or safety is the effect of a staphylococcus aureus infection. It is submitted that much of what follows should be relatively uncontroversial. Staphylococcus aureus toxins can cause bleeding[81]. Thus, even if it not the cause of death, its presence is relevant to understanding the possible causes of bleeding found in Harry. The relevant areas of bleeding were scleral haemorrhages, petechial haemorrhages and claimed bleeding connected with the spine. Staphylococcus aureus toxins may also damage cells[82]. This is of importance in connection with the changes to the cells in the temporal lobe. Dr Keeling seems to accept this, albeit as a theoretical possibility[83]. Thus the existence of staphylococcus aureus infection may have helped explain all the post-mortem findings which caused concern in Harry's case[84] (other than the disputed evidence given by Dr Williams relating to the ribs and the finding of haemosiderosis). This is the case even if staphylococcus aureus did not cause death. It is in fact likely that staphylococcus aureus caused Harry's death. It is not possible to be certain of the mechanism[85]. All that can be said with confidence is that bacterial toxins can kill without leaving any histological signs[86]. Toxic shock and septic shock[87] are both possible causes of death. Staphylococcus aureus commonly causes septicaemia without any primary focus of infection[88]. It is accepted by all concerned that staphylococcus aureus in the CSF can cause meningitis, albeit infrequently[89]. Dr Walters' estimate from the published data is that staphylococcus aureus meningitis constitutes 2-10% of all cases of bacterial meningitis. If the polymorph reaction was not caused by red blood cells in the CSF then the only possible source for the polymorphs and the raised protein is from inflammation of the meninges. Thus, whether or not there is histological evidence of swelling in the meninges, there must be infection in them to produce polymorphs and raise the protein level[90]. The fact that the leukocyte level is above the normal limit but lower than that seen in bacterial meningitis[91] is consistent with the known delay in the rise of white cells in the CSF after the onset of rapidly progressive meningitis[92]. It is also consistent with the data that shows that cerebrospinal fluid in children shows less inflammation than for non- infants[93]. Indeed children with culture proven meningitis may sometimes have normal white cell count[94]. The primary reason for the rejection of the diagnosis of staphylococcus aureus meningitis is the absence of histological change[95]. However it appears to be well recognised that bacterial toxins can produces death or life threatening events without any histological change, even in adults[96]. The likelihood of death is enhanced when, as was the case with Harry, the presence of antibodies are at their lowest levels[97]. The effect of the dose of calpol given to Harry after he was immunised may also have a role to play in suppressing inflammatory responses[98]. The presence of staphylococcus aureus in cases has uncontroversially been accepted as being related to sudden infant death even in cases where there is no histological change[99]. Even the prosecution accept that death can occur very rapidly in very young children[100]. What they have failed to accept however is the logical consequence of that concession, namely that in the case of rapid death there is unlikely to be any specific histological change. CSF sampling is likely to be the most sensitive method of testing for the signs of early infection and meningitis[101]. It is a matter of basic physiology that polymorphs will be present before there is any histological change or visible pus on the surface of the brain[102]. Dr Wilson appears to accept this proposition on behalf of the prosecution. "I agree that the central nervous system findings would be compatible with an injury leading to bleeding and inflammation of the meninges before death. I agree that an illness lasting several days before death would have resulted in more striking findings at post mortem, particularly abcesses and purulent meningitis.[103]" The point is made more forcefully by Dr Wilson in the following passage: "In meningitis the usual progression would be bacteria alone, bacteria plus lymphocytes and then bacteria plus polymorphs over a period of 3 - 5 hours.[104]" Once there is infection, a toxic reaction may cause death at any time. The likelihood of death is considerably increased if there is no known focus of infection[105]. Although the prosecution originally suggested that the absence of any finding of the toxins TSST and SEA-SED was conclusive to show that there had been no toxic shock[106] or other toxic effect, it is now appears to be accepted[107] that staphylococcus aureus produces a number of toxins other than the toxins tested for[108], including staphylococcal enterotoxin E (SEE)[109] and F[110], as well as alpha, beta, gamma and delta toxins that damage cell membranes[111]. The bacterial cell wall can produce peptido glycan toxin[112]. There are also other components of staphylococcus aureus that can produce strong inflammatory responses[113]. The argument is not illuminated by the statement of Dr Klein which contains the unsupported assertion that there can be no meningitis without histological change. He is not a pathologist and therefore would never have cause to examine or understand sudden deaths where there is no sign of histological change. His assertion that there must be symptoms and histological change is understandable given that his practice is solely concerned with living but obviously sick children. Dr Klein's assertion cannot stand in the face of documented examples of children and adults who have died as a result of toxins without any histological changes being present[114]. Dr Klein's evidence is also undermined by the fact that staphylococcus aureus is now being identified as a possible cause of SIDS. If this identification is correct, it also supports the proposition that death may be caused by staphylococcus aureus without any associated histological change. The proposed connection between staphylococcus aureus and SIDS also answers Dr Keeling's point that there cannot be a disease which either colonises (not producing disease) or kills rapidly. If the possibility (which she has acknowledged in a paper of which she is a co-author)[115] that "pyrogenic toxins of Staphylococcus aureus are involved in .sudden infant death" exists, then staphylococcus aureus infection may be just such a disease. The rate of infection with staphylococcus aureus fits the mathematical model for SIDS. It occurs with greater frequency in boys, in the winter months, when babies are put to sleep on their fronts or on old mattresses, all of which were otherwise inexplicable epidemiological features of the incidence of SIDS[116]. On investigation, staphylococcus aureus toxins have been detected in the tissues of more than 50% of SIDS victims (as compared to a much lower level in infants who died of other causes)[117]. 3. The impact on Dr Williams? It is not proposed to repeat the matters set out above, under the heading 'Good Faith'. It is clear that the fact of non disclosure raises questions about Dr Williams' credibility and competence. The presence of staphylococcus aureus in a pure culture, leukocytes, polymorphs and a raised protein level ought to have suggested to Dr Williams at least the possibility of bacterial meningitis, even if it may not have caused death[118]. Dr Klein agrees that the CSF leukocytes is consistent with meningitis. Dr Wilson states: "It is not possible to exclude meningitis.[119]" On any view it was a possibility that ought to have been frankly disclosed and debated. There are only two possibilities. Either Dr Williams is so incompetent or negligent that he failed to recognise early signs of bacterial meningitis or he was deliberately unwilling to acknowledge or admit that possibility, having set a murder investigation in train. 73 million to 1 Despite the prosecution's claim that the 1 in 73 million statistic was and is irrelevant, this was not the stance taken at trial. The prosecution in closing and the trial judge in summing up both emphasised the statistic. The jury must have believed that it was relevant. If it is now conceded it was irrelevant and the Court of Appeal has determined that the judges' direction on the topic was inadequate to avert the danger of the 'prosecutor's fallacy'[120], it is necessary to evaluate the impact of the wrongly admitted evidence and the mistaken summing up on the juries verdict. In addition to this, the Court must give weight to the uncontested fresh evidence that shows the first Court of Appeal (and the parties) were misled into thinking that, whatever the true statistical figure might be, a cot death would still be a rare or unusual event. This fact was highly material to the conclusion of the Court of Appeal that the convictions were safe[121]. However as Professor Hill has now demonstrated, in any family unlucky enough to suffer a first SIDS, a second SIDS death is not a rare event at all. Odds of 1 in 260 have been estimated[122] or 1 in 100[123]. The figure of 73 million to 1 or any evidence of rarity would have had an effect on the jury. It is now accepted that the evidence was inadmissible. It should therefore never have been led. If true, the evidence was profoundly damaging. Further the damage was exacerbated by the fact that the jury were never adequately warned about the dangers of believing that the odds of innocence were 73 million to 1. The facts must now be reconsidered in the light of the substantially diminished certainty that can be attached to the prosecution medical case. The diminished medical evidence also has a knock on effect on the "circumstantial evidence" relied upon. It would be quite wrong, for example, to continue to place weight on the absence of explanations from Sally Clark for the bleeding found in Harry, given the finding of staphylococcus. Once the evidence is reassessed in this new light it is not possible to conclude that the giving of the flawed statistic and the misdirection did not have any substantial effect upon the jury. The approach of the Prosecution The prosecution seek to obscure the real injustice caused by their non disclosure and misleading use of statistics by seeking to argue that nothing has changed. This is unrealistic and wrong. The errors that have permeated this case have a widespread ripple effect. No one aspect can be considered and dismissed in isolation. For example the non disclosure will have affected all the evidence in relation to Harry's case. Sally Clark may have been regarded as less credible by the jury because she had no idea what may have killed him. The defence experts may have suffered a similar fate. The prosecution place considerable weight on the defence concessions extracted in cross examination on the assumption that "the medical findings were genuine"[124]. The concessions made by the defence experts would, in all probability, not have been made if Dr Williams' part and purpose in the non disclosure had been appreciated by those involved. Similarly little weight can be given to the prosecution list of similarities[125] if the fresh evidence is or may be credible. The critical similarities of "previous abuse" and "deliberate injury" or "recent abuse" can only be safely relied upon if the Court is satisfied that Dr Williams is competent and honest and that the bleeding observed cannot have been caused by staphylococcus aureus. In addition the prosecution give considerable currency to the 'hallmark' features of infant killing identified by Professor Meadow. It is not accepted that such evidence is admissible. The evidence does not qualify as expert evidence. The subject matter of the opinion is not such as to require special assistance to be given to the jury. It consist of no more than a list of commonplace features that a jury would not need help with[126]. A jury does not need Professor Meadow to tell them, for example, that inconsistent accounts from parents or the previous abuse of a child or the child being well immediately before it died may all be relevant in deciding whether a child has been murdered by a parent. Even the subject falls within the class of subjects upon which expert testimony may be permitted, there is no sufficiently organised body of knowledge or research that ensures that any opinion expressed on the subject is reliable. The body of knowledge relied upon by Professor Meadow was no more than his own experience over 20 years. However almost none of the underlying materials or data upon which Professor Meadow's opinion in based is now available. Access to the material was requested before trial[127]. The request was denied. Professor Meadow claimed to have destroyed the majority of the information on which his published results were based[128]. It is therefore impossible to examine the claimed scientific basis for his opinions. The destruction of the material would also clearly render the admission of the opinion unfair, even if it was strictly admissible. Retrial There is now clear and compelling evidence in favour of proposition that Harry died a natural death. There are a series of reports (above and beyond the evidence to be called on appeal) that demonstrate that there is a substantial and highly respectable body of national and international medical opinion that considers Harry died as a result of overwhelming staphylococcus aureus infection[129]. The alternative case on shaking or smothering is substantially weakened by the existence of an explanation for the acknowledged bleeding and petechiae observed at post mortem. The case on shaking is further weakened by the complete absence of any of the classic signs of shaken baby syndrome (such as axonal damage) and the inability of any expert to describe the mechanics of the trauma suggested by the prosecution. The case against Christopher is equally diminished. His cause of the death has always been in doubt. Death was originally unequivocally ascribed to a natural cause by Dr Williams. The prosecution experts, save for Williams, have gone no further than saying the cause is still unascertained[130]. The defence have similarly concluded that the cause is unascertained and the further experts consulted since the convictions support that view[131]. Professor David, the independent court appointed expert, has suggested that death might have been caused by acute idiopathic pulmonary haemosiderosis. Only Dr Williams has been willing to confidently ascribe death to smothering. Dr Gullino has concluded that acute idiopathic pulmonary haemosiderosis is a reasonable possibility and has also pointed to the growing support for Professor David's independent diagnosis of that condition. No other diagnosis fits the findings and explains the now accepted evidence of Stephen Clark that Christopher suffered a spontaneous nose bleed from both nostrils whilst in his sole care in London two weeks before his death. On the face of the totality of the medical evidence it is submitted that the case on Christopher would not get past the close of the prosecution case. It would certainly not end in a conviction. The time has come to draw a line under these deaths. It requires no imagination to appreciate that devastation that the deaths and these proceedings have already caused in the Clark family. As lawyers it is easy to understand the professional disgrace that has befallen Sally Clark (as well as the vilification of her husband for standing by her). More poignantly it has led to (name), their surviving child, reaching the age of 4 barely knowing his mother. Sally Clark has completed 3 years of sentence of life imprisonment with a recommended tariff of 15 years and has had to mourn the death of her children whilst being held out to be their murderer. The lives of the family have been laid waste by the seeming certainty of doctors where certainty was not justified. It is impossible to carry out further tests to determine the various hypotheses that have now emerged as to the cause of Harry's death. Harry was cremated after the defence experts advised that (on the material then know to them) all the appropriate tests had been carried. There are now only a limited range of medical samples available. This situation is due to the non disclosure, coupled with the failure of Dr Williams to undertake sufficient routine dissection and histology[132]. It cannot be right to have a murder trial where the central issue, namely what caused the death of the alleged victim, cannot be fully and properly investigated. As Professor Byard has commented: "The Clark brothers demonstrate difficulties that may arise if cases are not fully investigated with all the results being clearly summarised and discussed in the autopsy reports. Trying to clarify findings diagnoses and circumstances of death at a later stage may simply not be feasible due to the wide variety of possibilities other than inflicted injury." The process of this appeal has also been marked by a reluctance by the Crown to make speedy enquiries or realistic concessions. In addition there has been widespread publicity given to material, introduced by the prosecution, that could never feature in any retrial. The evidence about 73 million to 1 has, as the prosecution accepts, "attracted enormous and largely ill-informed media comment both during and after the trial.[133]" In addition the prosecution chose, for forensic reasons, to introduce and emphasise at sentencing and at the first appeal the suggestion that Sally Clark was abusing alcohol. Not only was the evidence introduced without any defence opportunity to challenge it, but it also served no purpose other than ensuring maximum publicity (Harrison J having ruled that alcohol had played no part in the death of the children). There must be considerable doubt whether these irrelevant factors may not be so widely imprinted on the public consciousness as to jeopardise a fair trial. In the circumstances it is submitted that it would not be an appropriate case in which to order a retrial.
