Consistently ranked in the Directories and picked by Legal Week as one of the most promising juniors at the Bar, Helen has a broad criminal, civil and public law practice, with a focus on criminal justice and human rights.
Helen prosecutes and defends in criminal matters. Alongside trial work, she regularly advises at the investigatory stage and has appeared in criminal cases before the Court of Appeal, Supreme Court, Privy Council and European Court of Human Rights. She has particular expertise in fraud, corruption, money laundering and financial crime. She has advised on and appeared in private prosecutions, both for the prosecution and defence.

Helen is regularly instructed in criminal justice related public law matters, including challenges to decisions not to prosecute and claims concerning the application of human rights law in the criminal context. Her current instructions include: acting (led by Clare Montgomery QC) for two individuals subjected to extraordinary rendition to Libya in a challenge to the DPP’s decision not to prosecute a senior member of MI6 for his alleged involvement; acting (led by Dan Squires QC) for individuals challenging the decision to nominate them for inclusion on the UN financial sanctions list; successfully challenging the caution administered to a man detained using a spit hood by the British Transport Police at London Bridge station.

Helen is experienced in claims with a national security context, concerning the intelligence services or undercover policing, and is familiar with closed material procedures under the Justice and Security Act 2013. She is currently instructed (with Danny Friedman QC and Dan Squires QC) for several Libyan claimants in connection with their alleged mistreatment in this country and abroad by the UK intelligence services in conjunction with foreign intelligence agencies. She has experience of proceedings before the Investigatory Powers Tribunal and in SIAC, including having acted (led by Tim Owen QC) for a young Russian woman accused of espionage in the only such case to be heard by SIAC. She was junior counsel (led by Richard Hermer QC) in the first trial against the Ministry of Defence arising out of the alleged detention and mistreatment of Iraqi civilians during the war.

She is regularly instructed in cases concerning serious police failings, including those leading to death or serious injury, and has experience of claims under the HRA, the Equality Act, the Data Protection Act and for misfeasance and malicious prosecution. She acts both for the victims of crime and for those accused of involvement in criminal offences. Her recent and current instructions in this area include: junior counsel (led by Karon Monaghan QC) for interveners before the Supreme Court in DSD v Commissioner of the Metropolis, concerning the nature and scope of the Art 3 investigative duty; and acting for individuals and families subjected to or bereaved by domestic violence in their claims for breaches of the investigative and protective duties by their local police forces.
