Practice Profile

Sam is a specialist criminal barrister, instructed for both prosecution and defence. His practice is focused on serious and complex cases, usually involving organised crime, violence, firearms, drugs, and fraud. He is on the CPS General Crime, Serious Crime, and Fraud Panels at Level 3.

As a committed advocate, Sam places great emphasis on thorough preparation and engaging with the real issues in a case, allowing for first-class advocacy before judge or jury. Formerly an IT developer, Sam is at ease conducting cases involving digital evidence. He draws on his experience to quickly analyse and present high-volumes of complex information. He is experienced with cases consisting of many moving parts, usually involving complex facts, multiple defendants, and lots of pieces of evidence to sift through.

Recent instructions have included:

  • Leading junior in an eight-handed money laundering case arising from a sophisticated fraud against a telecommunications company.
  • Sole and led junior in various EncroChat (Operation Venetic) cases, including a seven-handed conspiracy to supply cocaine and a three-week trial involving technical admissibility challenges.
  • Led junior in a 16-week importation trial, involving 270kg of cocaine, 2500kg of cannabis and 18.6m duty-free cigarettes hidden inside shipping containers.
  • Led junior in an attempted murder arising from the alleged sale of a revolver, where a 12-bore shotgun was then fired twice through the letterbox of a dwelling.
  • Led junior in the final trial of Operation Melrose, the investigation into the deaths of 39 Vietnamese migrants found inside a lorry in Essex in 2019.
  • Led junior in a 'Flying Squad' conspiracy focused on an OCG committing a series of robberies and burglaries across London.
  • Led junior in a complex diminished responsibility murder trial, prosecuting a defendant with a previous conviction for an unlawful killing in similar circumstances.
  • Sole junior in a sophisticated fraud involving complex computing evidence, where the defendants had created a website to steal online banking information.
  • Sole junior in a computer misuse and fraud case, where the defendants had allegedly sold access to the NHS Covid-19 vaccination database.
  • Sole junior in a three-handed conspiracy to defraud a vulnerable victim of £170k.

Sam has also been instructed in several long-term projects, including the Post Office 'Horizon' disclosure review, an SFO disclosure review, and a secondment to one of the CPS Crown Court teams. He was recently a keynote speaker at the Cityforum Digital Forensics Summit, presenting on the uses of digital forensic evidence in jury trials.

Outside of law, Sam is a keen skier, snowboarder, and scuba diver. He previously competed internationally for Great Britain in Canoe Marathon.
