Terrorism

R v B - Arrested on suspicion of being a terrorist under the provisions of section 41, Terrorism Act 2000. The defendant had a keen interest in firearms. A search of his property revealed a mass of literature, which showed a sympathy to the far right. Chemicals had been purchased as well as electrical components which, taken together, meant that Crown argued at the Newton hearing that this defendant intended to make improvised electrical devices. The charges laid reflected the extensive material sourced as well all other terror related equipment in his possession.
R v K - Led junior at the sentencing stage of the British jihadist who travelled to Syria to join militant group.
R v SW - Operation Overt: Trans-Atlantic airline liquid bomb conspiracy.
R v M - Chemical weapons (ricin) manufacturer alleged to be in preparation for mass terrorist killing.

Homicide

R v RLP & Ors - Led Junior for 1st defendant in multi-handed murder. The case involved a significant ‘gang’ background where it was said that the motive was in response to an earlier assault on the defendant’s group. An initial carjacking was followed by what the Crown described as a ‘ride out’: this group armed with knives and weapons attended their opposition’s homes. The escalation of violence culminated in the death of a 16 year old, attacked and killed in front of his mother. The case saw complex phone and scientific evidence presented and a cut throat defence deployed by the co-defendants against RLP. Adding to the difficulty in this case the defendant’s father was called by the prosecution to give evidence against his son in relation to a confession said to have been made to him in the aftermath of the killing.
R v T & Ors - Led Junior. Double murder, two men stabbed to death on a residential street in NW7. This case involved a background of drug dealing and financial debt. Some of the incident was witnessed by members of the public but when police arrived they could only find traces of blood and associated paraphernalia. Within a short time, the first defendant, was found bleeding heavily from stab wounds. Police searched his vehicle to find the body of the first victim in the boot. The body of a second man was found in a ditch some distance away.
R v K & Ors - Led Junior for the first defendant. A multi-handed murder. The killing of the deceased in broad daylight related to a revenge attack following the robbery of the first defendant. In the aftermath of the robbery, the defendants were said to have planned the murder, first locating the mobile phone, collecting the firearm and then attending the scene. At the scene a co-defendant indiscriminately opened fire, killing an innocent bystander. This case involved a number of anonymous eye-witnesses who gave evidence through a modulated voice system.
R v G and another - Led Junior in a double-handed murder. Defendant was charged alongside a teenager. A cut throat defence was launched. Initial premise was a road rage incident but it soon became apparent that the parties were known to each other, working for rival drug gangs. The case was further complicated by the co-defendant’s girlfriend having been romantically involved with the deceased.
R v C - attempted murder of two victims. The defendant entered his brother’s restaurant and opened fire injuring his brother and seriously injuring his Aunt. This case was eventually resolved by way of pleas to section 18 and to related firearm offences.
R v CC - Defendant acquitted of manslaughter. He had pleaded guilty to an offence of s20 GBH in 2004, following an assault committed when he was 15; despite unpleasant injuries the deceased had no injury to the brain. He was discharged from hospital but 2 days later he collapsed and was admitted to hospital with an acute subdural haematoma which caused him to be in a persistent vegetative state until his death 17 years later. The case invoked complex legal issues as to the original plea. Causation was a key issue and the case detailed consideration of medical evidence.
R v D - juvenile defendant accused of the murder of a rival drug dealer.
R v McA & Ors - multi handed murder caused by arson resulting in the death of one and significant injuries of others. The defendant was also charged with perverting the course of justice.

Serious violence and Sexual Offences

R v B & Ors - This case involved 24 defendants, split over three trials. Serious sexual abuse committed by three generations of family members and friends, between 2007 and 2017 on their own children and relatives. A number of the complainants had significant learning difficulties. Social Service and other associated agencies involvement in the case was substantial. Counsel’s involvement in this case was up to trial. She was responsible for all legal argument prior to the trial which was both substantial and complex. A large proportion of the evidence was heard before the main trial (section 28 hearings).
R v C - Leading junior. A multi-handed case. The indictment alleged the false imprisonment and blackmail of two different complainants. A young woman had been brought from Ipswich to London and had been kept in a house against her will. Threats and violence ensued against her and a demand was made for a large sum from her ‘friend’. The second complainant was a lodger at this London address and had witnessed the incident, he was then taken to Wolverhampton. Counsel was involved in the first two trials.
R v W - Defendant was allegedly ten years old when he was said to have begun sexually assaulting his younger nieces. All parties were of school age. The allegations were multiple, including anal and vaginal rape of both complainants as well as counts of indecency and indecent assault. The allegations did not come to light until the end of 2016.
R v L - Leading counsel. Multiple sexual offending alleged against three young victims.
