Sarah has a busy and varied criminal practice. She appears primarily in in the Crown Court, and occasionally in the Magistrates Court and the Youth Court.

She practises in all areas of crime, including offences against the person in both domestic and non-domestic contexts, drugs, possession of offensive weapons, driving offences, offences of dishonesty including burglary, theft and fraud, as well as breach proceedings and behaviour orders proceedings.

Sarah is able to grasp complex legal issues quickly and possesses mature strategy skills for her level of seniority. She is meticulous in her preparation and in the presentation of her cases at trial. She is also very approachable, puts her clients at ease, and she always ensures that her clients fully understand court proceedings and the strengths and weaknesses of their cases to allow them to make fully informed decisions. She is a confident advocate who is committed to representing her clients’ interests actively and fearlessly.

In the Crown Court, Sarah represents and advises clients at PTPHs, all interim hearings and at trial. She also appears in sentencing hearings in which she regularly secures very favourable results for her clients. Please see Notable Cases section for more details.

In the Magistrates Court, she has represented clients in numerous first appearances, sentencing hearings and bail applications. She has successfully opposed applications for special measures and made successful submissions on venue for trial. She has also represented clients in summary trials and contested Criminal Behaviour Order applications. She made successful submissions on issues of service and notice in an application to discharge a Restraining Order 16 years after the order was made, where the police and CPS had difficulties notifying the victim of the application; the application was granted and the Restraining Order discharged.

Sarah had previously completed pupillage with us, during which she shadowed and assisted John-Paul MacNamara in R v JM (Croydon Crown Court), a multi-handed trial for conspiracy to sell firearms and ammunitions, in which our client was the only Defendant to be acquitted – please click here for more details. She also assisted John-Paul in R v AS in Southwark CC where she drafted a skeleton argument to quash counts on the indictment arguing that the indictment was overloaded; following minor amendments from John-Paul, the application was made and succeeded. From a 9-count indictment, two counts were left to lie on the file as a result, two were deleted following the complainant’s admission to having lied, an alternative count was further deleted and the jury returned a not guilty verdict and three guilty verdicts on the remaining counts. She has generally gained extensive experience in drafting legal arguments, sentencing and legal research.

In her rather limited spare time, Sarah teaches advocacy as a tutor with the Education department of the Honourable Society of Lincoln’s Inn on BPTC students courses and residential weekends. She also volunteers to mentor and/or assist those seeking pupillage.
