“You have requested disclosure of a number of documents which you believe are capable of establishing that two silencers featured in the case and not one, as relied upon by the Prosecution at the trial. To clarify the context of your request, the issue at trial was whether the murderer was Jeremy Bamber (JB) as the prosecution contended, or Sheila Caffell (SC), his adoptive sister, as the defence contended. A critical part of the prosecution case in proving it was JB who fired the shots lay in the expert analysis of blood staining discovered on the silencer which was received in the gun cupboard some days after the murder by members of the family. Accordingly, any evidence that suggests that there was or may have been another silencer for the rifle would raise the possibility that it was that other silencer which was used during the shooting or part of the shooting and not the one alleged by the prosecution.Such a possibility would significantly undermine the case against JB, and any material supporting such a possibility would plainly be ‘material which casts doubt on the safety of the conviction’ given that both the size and smearing on the silencer relied on by the prosecution was central to the claim that it must have been attached to the rifle when SC was shot and SC could not have shot herself with the silencer on.”
“I also note from at least 2002 the defence have been aware of the suggestion from two sources referred to, suggesting that two silencers existed. The defence was also in possession of all forensic evidence which demonstrated the changed exhibit numbers of the silencers from the outset and chose not to argue this point on appeal, the Criminal Cases Review Commission having referred the case to the Court of Appeal.”
“Secondly, we do not accept at this stage that two separate silencers were examined. Neither do we accept your assertion that in our letter of11 May 2018 we gave an indication, open or otherwise that if there were two silencers, that of itself would significantly undermine the case against your client or that your client’s conviction was unsafe. That is not what we said and, for the avoidance of doubt the prosecution make no such concession.”
“We have carefully considered your letter and attachments but are not persuaded that any of the submissions, material or documents, either taken separately or together, hold out any prospect that any further enquiries by the Crown Prosecution Service will uncover anything that may affect the safety of Mr Bamber’s conviction. Accordingly, the CPS does not accede to your requests for disclosure.”
“The jury were entitled to know that Essex Police seized two paint samples from White House Farm, one on14 August 1985 and one on14 September 1985 . The CPS stated in their ‘November’ letter that a silencer was examined by Louise Floate on12 September 1985 . The CPS refuse to disclose this evidence from Louise Floate, or disclose the General Examination Record for the examination of red paint sample RM/1. Disclosure of this evidence would establish that someone had contaminated the knurling pattern of a silencer after12 September 1985 .”
“30 All the stages thus far considered are ones at which the criminal justice process remains afoot, with either trial or sentence or appeal to be catered for. When it comes to the position after the process is complete, the Attorney General’s guidelines deal specifically with disclosure of something affecting the safety of that conviction. The relevant paragraph in the most recent edition (2013), echoing the same principle in earlier editions, says this: ‘Post-conviction 72. Where, after the conclusion of proceedings, material comes to light, that might cast doubt on the safety of the conviction, the prosecutor must consider disclosure of such material.’ The guideline must mean that not only should disclosure of such material be considered, but that it should be made unless there is good reason why not. Thus read, it is entirely consistent with the principle reflected in the position set out in the paragraphs above in relation to the pre-Crown Court stage, to the pending sentence stage and to the pending appeal stage. Mr Southey’s submission entails the argument that the guidelines greatly understate the duty in the circumstances of the present claimant. He is entitled, if Mr Southey is right, to the full extent of the duty which the Crown had had during his trial. That would mean a duty to give active consideration, presumably continuously, to the state of the evidence. And, as the requests made of the police in the present case illustrate, it would mean a duty to respond from time to time to any requests for information, or for access to material, which the convicted defendant makes. The argument appears to be that his right to the performance of that duty endures indefinitely, or certainly whilst he, or perhaps anyone else, asserts that the conviction was wrong.”
“35 There can be no doubt that if the police or prosecution come into possession, after the appellate process is exhausted, of something new which might afford arguable grounds for contending that the conviction was unsafe, it is their duty to disclose it to the convicted defendant. Simple examples might include a new (and credible) confession by someone else, or the discovery, incidentally to a different investigation, of a pattern, or of evidence, which throws doubt on the original conviction. Sometimes such material may appear unexpectedly and adventitiously; in other cases it may be the result of a re-opening by the police of the inquiry. In either case, the new material is likely to be unknown to the convicted defendant unless disclosed to him. In all such cases, there is a clear obligation to disclose it. Para 72 of the Attorney General’s guidelines, quoted above, correctly recognises this. This is, however, plainly different from an obligation not to reveal something new, but to afford renewed access to something disclosed at time of trial, or to undertake further inquiries at the request of the convicted defendant.”
“We note that, despite our letter of21 September 2018 , you continue to characterise the letter of11 May 2018 as containing a concession that the existence of a second silencer would be a basis for concluding that the convictions might be unsafe. The paragraph you rely on in the letter of 11 May clearly states that the writer was setting out the context of your request, which included a summary of the significance which you would argue attaches to your second silencer theory. It was not a concession, as was made clear to you in the later letter of21 September 2018 .”
