Chambers prides itself on providing a first-class and highly professional prosecution service. We work predominantly for the Crown Prosecution Service and its various units that include Homicide, Organised Crime, RASSO and Complex Casework as well as its borough groups. Our team is led by Mark Heywood QC who was the First Senior Treasury Counsel at the Central Criminal Court between 2015 & 2018. Jonathan Polnay is Junior Treasury Counsel and Catherine Pattison is currently being monitored as a prospective Junior Treasury Counsel. Chambers also boast a number of highly-experienced Queen’s Counsel as well as leading juniors who undertake Grade 4 work. Many members of Chambers are accredited with and prosecute for the Crown Prosecution Service Rape and Serious Sexual Offences Unit. Their expertise is recognised by the Legal 500 who recently described us as a set with “excellent sexual offence specialists”. We encourage junior members to prosecute at the outset of their careers and they therefore often have prosecution experience beyond their call.

Although much of our work is for the Crown Prosecution Service, we have acted for the Serious Fraud Office and a number of members have undertaken secondments to assist with disclosure work on some of the most high-profile recent fraud cases. In addition, we act for many local authorities and other government agencies. In this respect, our members have acted in a number of prosecutions involving trading standards, regulatory and disciplinary matters, consumer credit, consumer protection, counterfeit goods and food and product safety.

We understand that a successful prosecution involves teamwork and we ensure that members are approachable and hands on. Our policy is to provide written advice, in line with the Farquharson guidelines, within seven days of receiving new instructions. In addition, we ensure that written records of hearings are provided to our instructing solicitors irrespective of whether a representative is at the hearing. We ensure that any enquiries, be they as to disclosure, further advice, case strategy or case building, are dealt with efficiently. 

Members of the prosecution team are available to assist in private prosecutions. We also are asked for and provide pre-charge advice and advice on appellate work. For all prosecution-related enquiries, please contact the senior clerk Lee Hughes-Gage.

  • R v. Gordon Park [C.O.A.] 2019

    Lady in the Lake murder trial

    Louise Oakley was Junior Prosecution Counsel led by Richard Whittam QC before Lady Justice Sharp, Mr Justice Sweeney and Mrs Justice May in response to the CCRC’s  Referral  of the “Lady in Lake” case which was one of the UK’s longest murder enquires.

    Carol Park went missing on 17 July 1976, and was never seen alive again by her family. In 1997, her body was discovered by divers in Coniston Water.  She was nicknamed "the Lady in the Lake” by detectives. Carol Park’s husband (Gordon Park) was convicted of her murder in 2005. He appealed against his conviction, nut it was dismissed in 2008. Just over a year later, Gordon Park killed himself on his 65th birthday in his cell at HMP Garth.

    Gordon Park’s family applied on his behalf to the CCRC and following an eight year investigation they referred the case in 2018 to the Court of Appeal on the basis that there was a real possibility the Court of Appeal will consider the conviction is unsafe. The CCRC cited the cumulative effect of a number of issues, including the non-disclosure of expert opinion undermining the prosecution’s assertion that Gordon Park’s climbing axe could be the murder weapon, new scientific evidence showing that Gordon Park was not a contributor of DNA preserved within knots of the rope used to bind his wife’s body, non-disclosure of information undermining the reliability of a prosecution witness who gave evidence of a prison confession and a renewed assertion that a rock found in the lake near Carol Park’s remains could not specifically be linked to rocks at Bluestones, the family home, should be reassessed.

    The Appeal involved the instruction of forensic scientists, forensic pathologists and forensic odontologists and a review of legal, dental and medical records going back to 1976.
