Notable defence cases
R v TG, Central Criminal Court
Led by Lisa Bald in an eight-week trial on allegations of attempted murder, GBH and firearms offences. The defence successfully opposed prosecution applications to admit evidence of gang involvement (including drill videos and lyrics) and the hearsay by a co-defendant. TG was acquitted of attempted murder.
R v LW, Maidstone Crown Court
LW was unanimously acquitted of rape after a five-day trial. The case gave rise to complex issues bearing on the complainant’s sexual history and s.41 YJCEA 1999, the trial judge ruling that cross-examination was permitted on several subjects over objections by the prosecution.
R v CEA, Court of Appeal
CEA, a youth, had been sentenced in the Crown Court to a total of five years and nine months detention for offences of robbery, affray, possession of a bladed article and s.18 GBH. The sentence was reduced on appeal to three years and six months.
R v MD, Snaresbrook Crown Court
MD was acquitted of drug supply and money laundering. He faced evidence including police observations, phone analysis, and fingerprints on bags containing several kilograms of cocaine and a shoebox which held £100,000 cash.
R v GW, Chelmsford Crown Court
Led by Craig Rush in a two-week murder trial. GW was unanimously acquitted of murder and manslaughter.
R v HD, Maidstone Crown Court
HD was unanimously acquitted of rape following a four-day trial. Both defendant and complainant were vulnerable teenagers, though HD was 19 and the complainant 14. HD received a suspended sentence.
R v CC, Catterick Court Martial Centre (Appeal)
Simeon’s written argument prompted the Service Prosecuting Authority to abandon its opposition to CC’s appeal, accepting at a late stage that orders which CC accepted contravening were contrary to domestic law.
R v ZL, St Albans Crown Court
ZL was unanimously acquitted of s.18 GBH. He denied involvement in the stabbing of the complainant, who identified him having known him for some years.
R v KG, Basildon Crown Court
Simeon persuaded the CPS to offer no evidence on the day of trial, having obtained expert evidence which undermined the telephone data said to demonstrate KG’s involvement in supplying class A drugs.
R v AG, Catterick Court Martial Centre
AG, a serving officer, was acquitted of two counts of s.18 GBH after a five-day trial. Self-defence successful despite CCTV showing AG challenging others to a fight shortly before the incident.
R v DF, Cambridge Crown Court
Led by Craig Rush in an eight-week trial on charges including cannabis production, firearms and perverting the course of justice. The case raised complex issues of public interest immunity.
