Background
Darren Osment was convicted at Bristol Crown Court of murdering Claire Holland, his former partner and the mother of one of his children. Holland was last seen leaving a Bristol pub in June 2012, saying that she planned to meet Osment. Her body was never found, and her phone and bank account were not used again. The prosecution relied principally on numerous statements Osment made over nearly a decade in which he claimed responsibility for her death, including statements to acquaintances, police, an undercover officer and, allegedly, another prisoner.
Osment appealed on the basis of a post-trial disclosure failure. The prosecution had not disclosed that Charles Franklin, who was present at the pub, bought Holland a drink and left around closing time, was later convicted of rape and attempted rape arising from a November 2012 attack on a highly intoxicated woman. Osment also renewed applications for permission to appeal concerning the admission of his statements to the undercover officer and the exclusion of proposed expert evidence about suggestibility, false confessions and undercover questioning tactics.
The Court’s Holding
The Court of Appeal dismissed the appeal and refused permission on the renewed grounds. It agreed that Franklin’s convictions should have been disclosed, but held that the evidence would not have been admissible under section 100 of the Criminal Justice Act 2003. The later sexual attack was insufficiently similar to Holland’s disappearance and did not have substantial probative value on whether Franklin, rather than Osment, murdered her. The court therefore declined to receive it as fresh evidence under section 23 of the Criminal Appeal Act 1968.
The court also upheld the trial judge’s admission of Osment’s recorded statements to the undercover officer. The operation was lawful and properly supervised, and the judge was entitled to find no oppression, improper interrogation or conduct likely to make the statements unreliable under sections 76 or 78 of the Police and Criminal Evidence Act 1984. The proposed evidence from Professor Gudjonsson and Professors McManus and Oxburgh was properly excluded because it duplicated admissible clinical evidence or addressed the jury’s task of assessing the statements’ reliability.
Key Takeaways
- A prosecution disclosure failure does not make a conviction unsafe where the undisclosed material would not have been admissible or materially probative.
- Bad-character evidence concerning a possible alternative suspect must have substantial probative value on an important issue; broad similarities are insufficient.
- Recorded admissions to an undercover officer may be admitted where the operation creates an opportunity to speak but does not oppress, improperly interrogate or positively induce an unreliable confession.
Why It Matters
The decision illustrates the contextual assessment required when undisclosed evidence is said to implicate an alternative suspect. A court must evaluate that evidence against the entire case, including its similarities and differences, its connection to the alleged offence and the strength of the existing evidence.
It also confirms limits on expert evidence concerning confession reliability. Experts may explain a defendant’s clinically established vulnerabilities, but they generally may not duplicate other testimony or decide the ultimate factual question entrusted to the jury.
