Notable Cases

Operation Chiffon (2018): Led junior for the prosecution in one of the largest international drug importation networks investigated by  Greater Manchester Police, together with the National Crime Agency and Belgian authorities. Over £66m worth of drugs seized after being concealed in agricultural equipment and trailers delivered from Belgium to the UK via Holland.

R v Paterson [2017] EWCA Crim 1625: Led Junior in the high profile and unprecedented trial of a surgeon convicted of carrying out unnecessary operations on patients. The case concluded in the Court of Appeal following a reference by the Attorney General. As an acknowledgement of his work in this case Mr. Walmsley was awarded a ‘red bag’ by Nicholas Johnson QC.

Royal College of Nursing (2016): Completed a secondment to the Royal College of Nursing Legal Department, which provided invaluable experience of professional regulation from a unique perspective. Instructed to appear in the full range of proceedings, including, Investigating Committee hearings, Conduct and Competence Committees, and a Coroner’s Inquest.

R v Cushion [2015] EWCA Crim 1478: Appeal against sentence for offences of burglary dwelling and failure to surrender.

R v Childs [2015] EWCA Crim 665: Junior counsel led by Richard Pratt QC for a client that was convicted of joint enterprise murder following the death of a man during a fight in a retail park. The conviction was appealed, but leave refused by the single judge. The application to appeal was then renewed and subsequently granted by the full court. Following a full trial the conviction was quashed and substituted with manslaughter as the requisite intention for murder was unclear from the scientific evidence.

R v Kennedy (2015): Junior counsel led by Nicholas Johnson QC in the successful defence of murder where the client was alleged to have killed a 64-year-old man in her flat. There were complicated difficulties with causation, a consultant having missed the fatal injury when the deceased first went into hospital. The client was convicted of manslaughter and sentenced to 9 years’ imprisonment.

R v Hewitt & Others (2014): Junior counsel led by Andrew Fisher QC representing a child of fourteen years’ who was one of six teenagers accused of a joint enterprise murder of a man in the back room of a launderette in Liverpool with an old-fashioned sword-stick.

Mr Walmsley appeared against treasury counsel in front of the Lord Chief Justice.

R v Yates & Others (2008): Led junior for the defence of a young defendant in the high profile and, multi-handed, Rhys Jones murder case in Liverpool. This was a complex and sensitive matter that included groundbreaking applications to adduce hearsay and bad character evidence.

R v Crowcroft & Others (2007): Litigator for the defence in the first ever trial to prosecute British Serviceman for war crimes.
