What has the government done to change the regime of non-disclosure of evidence which has led to numerous miscarriages of justice?

Disclosure is still one of the most frequent causes of miscarriages of justice and the procedure of disclosure in the United Kingdom is one of deep concern. It is widely known that the procedure for disclosure introduced by the Criminal Procedure and investigations Act 1996 (CPIA) hasn’t really worked the way it should have; instead it considerably limits the defendants right to access information. Disclosure is now considered fundamental to the defendants’ right to a fair trial. However little attention has been given by the police service, which weaken this vital safeguard.

In the criminal justice system disclosure is the process by which the prosecution alerts the defence to the knowledge of any unused material (material does not form part of the prosecution case, hence the term ‘unused’) gathered during an investigation, but it can however weaken the prosecution or strengthen the defence. Therefore this can be priceless information for the defence as it can create the reasonable doubt required to win their battle in court. This therefore means that by law the defence has the right to access and to know of any material that can be used to strengthen their case. However it is not always seen to be the case by prosecutors or police where there priority is to obtain a conviction.

An example of how important this regime is and also the dire consequences of its failure is the case of Stefan kiszko; he was convicted in 1976 for the rape and murder of 11-year old Lesley Molseed in 1975. Evidence that showed he was sterile (which rendered him incapable of producing the forensic evidence found at the scene) was known to the prosecution but was not disclosed to the defence. He spent 16 years in prison before the documents were found to prove his innocence came to show and his conviction quashed, he was released in 1992, after a long campaign by his mother. He died of a heart attack the following year at the age of 41. In 2007, Ronald Castree, was found to have the same DNA as Lesley's attacker and was convicted at Bradford Crown Court.

Another miscarriage of justice due to non-disclosed information which continues to arise in expert evidence too is the case of Sally Clark who was convicted in 1996 of the murder of her two small sons Christopher and Harry. The convictions were based solely on the analysis of the deaths by the Home Office Pathologist Alan Williams, who failed to disclose relevant information about the deaths, and backed up by the paediatric professor Sir Roy Meadow. It later came to light that tests showed that Harry had  bacteria, suggesting that her second son may have died from natural causes, but the evidence had not been disclosed to the defence. This evidence had been known to the prosecution's pathologist, Alan Williams, since February 1998, but was not shared with police or lawyers. It became clearer that the statistical evidence presented at Clark's trial was seriously flawed. Her case was referred back to the  by the , and her convictions were overturned in a second appeal in January 2003. She was released from prison having served more than three years of her sentence.

Almost all of the most notorious miscarriages of justice have involved similar non-disclosure of critical evidence, such as psychiatric reports, which weaken a confession. In each case, material which would have exonerated the accused was deliberately withheld by the prosecution, with terrible consequences. The dangers of non disclosed information was highlighted in many cases especially the cases above, partly by police officers who find it ridiculous to have to gather information to help prevent a conviction, they can only do this after working hours and find it too time consuming, as they have to gather all information before the ...
