DNA and other forensic evidence

David has developed a particular specialism in DNA cases, appearing in many of the leading trials and appeals in this controversial field. This too has been noted by commentators, who state that “DNA evidence is his thing, and he has the ability to understand forensic stuff that is not easy" (Chambers Guide 2014).

This expertise includes "low template" DNA and complex mixed profiles, and he has extensive experience working with some of the foremost forensic scientists in this field. He has  co-authored comprehensive articles on DNA law and practice published in The Archbold Review September 2012 and February 2011 and well-received features in the Law Society Gazette, January 2015. He was also interviewed by the BBC for their recent R4 documentary “Forensics in Crisis” and was quoted in a recent news story relating to DNA contamination fears in sex cases.

He is a contributor to the recently published “Statistics and Probability for Advocates” guide produced jointly by the Inns of Court School of Advocacy and the Royal Society for Statistics.

His forensic expertise extends to cases involving pathological and psychiatric issues. This has been deployed to successful effect in a recent “baby shaking” acquittal, and in an ongoing automatism defence.



Potential miscarriages of justice are a particular area of interest, and he receives instructions on a referral basis on a range of serious cases – including being instructed to provide a second opinion, as assigned counsel by the Registrar of Criminal Appeals, and in cases involving referrals from the Criminal Cases Review Commission (CCRC).

He has several pending appeals. He is also advising on appeal in relation to a number of murder cases – some relating specifically to joint enterprise convictions based on the now discredited pre-Jogee foresight test and has recently authored an article on post- Jogee  joint enterprise appeals for the Law Society Gazette.

Currently advising a high profile overseas client re DNA issues at original trial.


Direct access

David accepts both public and privately funded instructions, and is accredited with the Bar Council to accept "public access" (direct) instructions in appropriate cases.



He has co-presented (along with leading US DNA expert Professor Dan Krane) seminars at Doughty Street Chambers and in-house with leading solicitors on recent developments in DNA law and practice.

He was invited to speak at an international seminar at Cambridge University in August 2016 on the use of probability and statistics in criminal cases.

He has guest lectured to students on the Forensic Science Masters Course at UCL in relation to DNA and expert evidence.

He has lectured on aspects of money laundering, and has contributed to the BBC’s "Law in Action". David provides training for a range of organisations including a leading media organisation (on crime-related media issues), the Criminal Cases Review Commission, Liberty and the DCA.

He has provided bespoke in-house legal training to top-tier firms involved in business crime.

He has a keen interest in international legal issues, and in 2015 was invited by the Foreign Office to travel to Shanghai where he spoke at a UK-China seminar on UK criminal justice perspectives; also  travelling to Hong Kong in 2016.
