Lord Justice Thomas :
i) Was the evidence new?ii) Was the evidence compelling?
iii) Was a re-trial in the interests of justice?
The original investigation
The trial
The further investigation
i) As to the area located by Pauline Stevens (areas 2, 3 and 4) on the right boot, that blood had been deposited when wet. She was unable to determine whether it was deposited as a result of the boot coming into contact with a surface wet with blood or whether blood had travelled through the air and landed on the boot to cause the blood staining (spattering).ii) As a result of STR profiling of the blood from areas 2, 3 and 4, a full STR profile that matched the profile of the deceased was obtained; the match probability was 1 billion to 1.
iii) Two very small blood stains (identified as area 7) were found on the right boot at the edge of the undersurface of the flap on which the lace eyelets were present. It was her opinion that these were deposited on the boot while the blood was wet. A partial STR profile was obtained showing DNA from at least two individuals. Although this could be explained by a mixture of DNA from the deceased and the respondent, there were components that could not have come from either of those individuals.
iv) Very small bloodstains were found near the heel of the right boot on the inner aspect (area 5). It was not possible to obtain a profile.
v) Three further possible bloodstains were found on the front toe area of the right boot (area 8). Two of these areas appeared to be very near that area where Ms Miller had cut the boot. No DNA profile could be obtained.
vi) Light blood staining was found on a fabric loop at the back of the left boot (area 6); it would have been deposited when wet. STR profiling was undertaken which produced a partial STR profile. All of the confirmed components matched corresponding components in the STR profile of the deceased and all but one of the unconfirmed DNA components matched the corresponding components of the STR profile of the respondent. However there was an additional unconfirmed component that could not have come from either the deceased or the respondent. Her opinion was that the match probability was approximately 1 in 55 million.
vii) As the profile results from area 6 (left boot) and area 7 (right boot) were mixed, it was not possible to determine which DNA components came from blood.
viii) As to the way in which the blood found at the base of the tongue on the right boot (areas 2, 3 and 4) may have been deposited, she did not consider that the bloodstain was of the type she would expect to find deposited by coming into contact with the ground or adjacent surfaces such as vegetation when walking, particularly as the weather following the assault was dry and hot. She concluded:
"[I]n my opinion it is highly improbable that the blood staining at the base of the tongue of the right boot was deposited as a result of [the respondent] walking through the scene after the assault on [the deceased]. If the bloodstains from the flap on the lace of the right boot and the fabric loop on the back of the left boot originated from [the deceased] I cannot envisage a scenario where these and the blood staining at the base of the tongue on the left boot would have been deposited by [the respondent] walking through the scene."
The application to the Court
Issue 1: Is the evidence new?
"Evidence is new if it was not adduced in the proceedings in which the person was acquitted …."
Issue 2: Is the evidence compelling?
"Evidence is compelling if –
(a) it is reliable,
(b) it is substantial, and
(c) in the context of the outstanding issues, it appears highly probative of the case against the acquitted person."
i) That it is accepted before us that the blood found at the base of the tongue (areas 2, 3 and 4) was that of the deceased andii) It was deposited when wet.
The question therefore arises as to how the blood came to be deposited on the boots. One obvious possibility is that the blood was deposited in the course of the attack on the deceased. The other possibilities are that (a) it was deposited on the boots after the attack on the deceased but before they were seized by the police on 13 September 1996 or (b) deposited by contamination after the seizure or (c) by some unexplained cause. If the last three alternatives can be eliminated as highly unlikely, then it is necessary to examine the strength of the first possibility.
(a) Was the blood deposited after the attack but before seizure of the boots by the police?`
(b) Was the blood transferred through contamination after seizure of the boots?
(c) Other possible explanations
i) It was the evidence of Ms Rosalyn Hammond, which we accept, that the examination of dark coloured boots for blood is in itself a difficult task. Furthermore, not only is the surface uneven, but it is difficult to examine them under a microscope. Because of these difficulties, it is possible for a competent examiner not to find visible traces of blood.ii) As we have set out at paragraph 8 above, the examination in 1995/1996 was conducted with extra lighting which was supplied by an angle-poise lamp with an ordinary domestic light bulb and not with halogen lighting used in 2008. It is very surprising to us that the FSS did not equip their laboratory at Aldermaston with the more powerful halogen lighting, particularly in view of the evidence of Ms Rosalyn Hammond that she used such lighting in 1995/1996. The lower level of intensity lighting provided by the ordinary domestic light bulb in the angle-poise lamp might be one explanation for failure to detect the blood that was found in 2008.
iii) The microscope used to examine the boot in 1995 was much less flexible than the microscopes used in 2008. It was much more difficult to manoeuvre a surface such as that of a boot under the microscope in use in 1995/6 than the microscope used in 2008. Again that might help explain why any blood there was not seen.
iv) It is apparent from what we have set out in paragraph 19 above that the further analysis and examination carried out under the supervision of Caroline Hughes detected areas of blood (areas 5, 6, 7 and 8) that had not been detected by the separate examinations carried out by Pauline Stevens and her assistant earlier in 2008. This was a very clear indication of the difficulty of detecting blood on surfaces such as boots and clear evidence that it was possible for competent scientists to miss blood.
v) The areas examined by Mr Mann in 1995 were not checked by Ms Miller in 1996 and the examination by Ms Miller in 1996 was not checked on its completion by Mr Mann. At that time it was not sufficiently appreciated that a second check was necessary. That is now firmly appreciated as a result of the report by Alan Rawley QC and Professor Caddy entitled "Damilola Taylor: an independent review of forensic examination of evidence by the Forensic Science Service" (published by the Home Office, April 2007). This report pointed to the inherent risk of human fallibility in the detection of bloodstains on surfaces. As a result, two examinations are now required, though there must remain the risk that even two will not detect all the blood. Again it seems that another explanation as to why the blood might have been present but not detected was the failure to conduct two examinations of the same areas in 1995/6.
(d) Deposit of the blood by contact with the deceased
Issue 3: Is it in the interests of justice to make an order for a re-trial?
"That question is to be determined having regard in particular to –
(a) whether existing circumstances make a fair trial unlikely;
(b) for the purposes of that question and otherwise, the length of time since the qualifying offence was allegedly committed;
(c) whether it is likely that the new evidence would have been adduced in the earlier proceedings against the acquitted person but for a failure by an officer or by a prosecutor to act with due diligence or expedition;
(d) whether, since those proceedings or, if later, since the commencement of this Part, any officer or prosecutor has failed to act with due diligence or expedition."
(a) The memory of witnesses
(b) The destruction of the transcripts of the trial
(c) Witnesses who have died
(d) The destruction of exhibits
(e) A failure of due diligence in the examination of the boots
"In subsection (2) references to an officer or prosecutor include references to a person charged with corresponding duties under the law in force elsewhere than in England and Wales."
Furthermore by s.95(1) the term officer is defined to mean "an officer of a police force or a customs and excise officer".
(f) Delay in the investigation
(g) The fallibility of scientific investigation
(h) Conclusion
Overall conclusion
