R v G  4 WLR 185,  EWCA Crim 1633 - One of the key authorities since the Ched Evans litigation on the application of s41 Youth Justice and Criminal Evidence Act 1999 (admissibility of evidence relating to previous sexual behaviour)
R v Hyde  EWCA Crim 713 and  EWCA Crim 1113 - This case involved an allegation of illegal brokering of an international arms deal for 80,000 guns and 32m rounds of ammunition, shipped between China and Nigeria. The first trial resulted in a successful submission of no case to answer, later reversed by Court of Appeal. After the retrial, David as junior Counsel then took (and won) a novel point on the correct interpretation of the forfeiture provisions of the Firearms Act 1968.
AG Ref 32 of 2013  EWCA Crim 1202 - The Attorney General referred the sentence of Billy Duggan to the Court of Appeal as being unduly lenient. David, acting alone, successfully resisted that application, with the Court finding that this was an exceptional case where the Defendant could be spared imprisonment.
Serious and Grave Crime
R v S – Successful defence to soliciting murder in a case that threw into sharp relief the difficulties in interpreting 19th century statute in the internet age. The Defendant had posted messages on a website on the ‘dark web’ inviting the murder of his new born child, allegedly to avoid CSA payments. David argued that an auto-response generated by the website was not sufficient for conviction; his client was acquitted.
R v O’Brien - David was sole Counsel for the first defendant of 14. This was an international conspiracy to steal items made of rhinoceros horn and priceless jade artefacts from British museums, with a total value of somewhere between £20M and £57M.
The case was widely reported at its conclusion – see for example http://www.theguardian.com/uk-news/2016/feb/29/chinese-artefacts-fourteen-men-convicted-british-museums-rhino-horn
R v Duggan - Allegation, as part of a particularly grisly murder trial, of conspiracy to pervert the course of justice by burning evidence and seeking to mutilate a corpse. The Defendant said that he was operating under duress from one of those ultimately convicted of murder. The Crown were forced to leave the case to the jury on the basis that he had been coerced, although not sufficiently for duress to operate, and the defendant was convicted only by majority. Because the Defence had established that there had been coercion, the Defendant was spared an immediate prison sentence.
R v McCaffrey- Junior Counsel for the first Defendant in a case of perverting the course of justice - an alleged attempt to use a rogue solicitor’s clerk to obtain information about a massive investigation into the supply of Class A drugs across the North of England. David’s client was acquitted at the close of the Crown’s case.
R v Campbell - Acquittal in an allegation of gunpoint robbery of a brothel in which the Defendant was said to be the gunman in a gang of five.
R v Baltais - Sole Counsel for first defendant of 10 – conspiracy to import 13kg of cocaine and heroin from Belgium to the United Kingdom.
R v Van Doesburg - This case alleged the importation of 108kg of cocaine into the UK, valued at £16.2M, secreted in the rudder-trunking area of a coal tanker that had crossed the Atlantic from Columbia. The Crown’s case was that the Defendant was part of a team assembled to recover the drugs using underwater diving equipment and a specially adapted inflatable boat, and attracted national media interest by virtue of its description as a ‘James Bond style’ plot.

David acted as junior Counsel in this case and his client was acquitted by the jury.
R v Aucott - David’s client was charged with 5 others in relation to the cultivation of cannabis. Despite not giving evidence, being arrested at the scene and having purportedly signed a confession, his client was the only defendant acquitted by the jury.
R v B - Sole Counsel for a defendant who had flown into the country to confess to extremely serious historical sexual offending against children.
R v CA - Successful application to dismiss a charge of controlling a person under 18 in prostitution. David’s client was himself a vulnerable young person; the Court accepted the argument that the proper interpretation of s49(1) Sexual Offences Act 2003 meant that he had no case to answer (although the case of three other men proceeded to trial).
R v C - The Defendant in this case was charged with three counts of historical rape against two different young girls. David was instructed as junior Counsel specifically to oppose an application whereby the Crown sought to use, as bad character, evidence of the complaint of a third girl; that opposition was successful.
R v A - The Defendant was charged with sexual assault and ABH in what was, effectively, an attempted rape on a vulnerable woman in the Defendant’s own home. Acquitted.
R v T - David’s client was first on the indictment in a six-handed case alleging historical sexual offences against young boys in a church choir in South London, involving complex legal argument relating to cross-admissibility of evidence from independent complainants, and the admission of ‘bad character’ of non-defendants as important explanatory evidence.
