R v R, Canterbury Crown Court, 2012. - Importation of Cannabis

The Defendant, a truck driver, was arrested at Dover Ferry Port. Thirty-six kilos of Cannabis were found secreted in his truck. He denied knowledge of the drugs stating that he believed the packages contained tobacco. The Defendant was an ex-soldier employed by a firm in Northern Ireland. After the provision of tachograph evidence to support his account in interview, and extensive disclosure requests by the Defence, the Crown offered no evidence on the drugs offence and accepted a plea by the Defendant to the fraudulent evasion of duty on tobacco that was recovered from his truck, for which he received a suspended sentence.

R v A, Inner London Crown Court, 2012. - Extreme Pornography

The Defendant pleaded guilty on an earlier occasion to a separate offence involving the possession of indecent images of children. The Defendant denied ever knowingly viewing these images or ever being aware that they were on his computer. After an expert report was commissioned by those instructing (on the advice of Counsel) representations were made to the Crown Prosecution Service. The Crown accepted that it could not prove to the requisite standard that the Defendant knowingly viewed or possessed these images and that such images could have been ‘cached’ by the Defendants computer browser without his knowledge. The Crown offered no evidence and the case was dropped.

R v M, Kingston Crown Court, 2012. - Sexual Assault

The Defendant was a young vulnerable man with psychiatric issues that had not been properly identified by his family. He was prone to behaviour that was out of his control, due to a lack of treatment and medication. Counsel, and those instructing, provided detailed advice from the arrest stage until final disposal at Court. Between these two stages the Defendant was properly assessed, and his illness diagnosed for the first time. This had a significant impact on the type of sentence he received and was the difference between an immediate custodial sentence and the suspended sentence that he received.

R v A and others, Central Criminal Court 2012. - Possession with intent to supply Class A Drugs

Tomas was instructed to advise a defendant and instructing solicitors on aspects of sentencing involving the provision of information to the police. The Defendant received a significantly reduced prison sentence.

The case involved extensive cell site evidence and the instruction of a defence expert to show that the Defendant was not in the vicinity at the time the victim had been picked up at that location

R v B, Birmingham Crown Court, 2011 - Fraud, False ID

It was alleged that the Defendant and a number of others defrauded the Islamic Bank of Britain of large sums of money. The Defendant volunteered answers in the police station and was unrepresented for much of the time pre charge. The case involved complex issues of phone evidence and bank transactions. The Defendant accepted that he had a false passport for other purposes and pleaded to this. At trial all of the co-defendants pleaded guilty and the Crown decided not to proceed against the Defendant on the more serious charges, as he pleaded to lesser offences earlier on. He was given a suspended sentence, whilst his co-defendants were imprisoned.

R v A, Court of Appeal, 2011 - Section 18 Assault

The Appellant had been convicted after a trial alleging assault occasioning grievous bodily harm. The single judge refused to grant leave. Counsel renewed the application and on appearing before the Full Court leave was granted.

The Defendant and another boy faced charges of serious assault against a homeless man, having been arrested near the scene. Both he and his co-defendant were present when a much older man assaulted the victim in this case. The Defendant accepted presence during the assault but denied encouragement or participation. After submissions from Counsel, at the close of the Crowns case, the judge ruled that there was a case to answer on some aspects of the Crowns case but not as the case was put before the Court. The Crown then accepted pleas to lesser offences and the Defendant, and his co-defendant received significantly shorter sentences than that which they would have received had they been convicted of GBH. The older man was convicted of GBH and received a lengthy custodial sentence.

R v W J- Court of Appeal, 2010 - Robbery

Appeal against sentence. The appellant was acquitted of murder but convicted of robbery and sentenced with a co-defendant (who was convicted of murder) to ten years. The appeal was allowed, and the sentence reduced to seven years.

R v S, Court of Appeal, 2010 - Fraud, False Representation

The Defendant pleaded guilty to a number of accounts alleging fraud. She was sentenced to a period of four and a half years in custody. The solicitor felt that an appeal was unlikely to succeed but Tomas advised that that matter should be appealed. The sentence was reduced to one of three years by the Court without need for oral argument.

R v P, Inner London Crown Court, 2009 - Assault occasioning actual bodily harm

It was alleged that the Defendant assaulted the victim while she was asleep. The defence accepted that an assault had taken place but disputed the mental element of the offence. The Defendant had been prescribed anti-depressant drugs and found that they caused him to feel strange impulses. His only recollection of the incident was a feeling of ‘floating on the ceiling, observing everything below’ and then coming to. As a man of good character with glowing references from his ex-wife and previous partners, and extensive research into the use of this drug and the instruction of an expert. On service of the report and, having consulted with the victim in the case the case (who agreed that the defendant’s actions were out of character), the Crown decided not to proceed against the Defendant and the matter was dealt with by way of a bind over.

At the close of the Crown’s case the judge ruled that there was no case to answer after counsel’s submissions.

R v J - Kingston Crown Court, 2009 - Possession with intent to supply Class A drugs

The Defendant was stopped as the driver of a car with three others. Crack cocaine was found under the driver’s seat. The Defendant was acquitted by a majority verdict.

R v C - Canterbury Crown Court, 2009 - Possession of false Id with intent

The Defendant had been travelling to Algeria to spend the summer there. He was stopped at Dover controls and was found to have a false British driving licence in his possession, as well as his French licence that entitled him to drive in the UK. His account was that he intended to use this false licence in Algeria only. The Defendant contested the matter at trial, despite an indication by the Court at an earlier hearing he did not have a defence in law. Vigorous representations were made by Counsel on the issue of the jurisdiction of the Court and the location where any offence was likely to be committed, but the Crown refused to drop the case. At trial Counsel made a submission of no case to answer, in accordance with these earlier representations and the learned judge agreed, ruling that there was no case to answer.

R v W, Maidstone Crown Court, 2009 - Rape, Sexual Assault

The Defendant was charged with others of allegations of rape and sexual assault against family members dating back to the 1980’s and 1990’s. The case involved complex issues of double jeopardy as verdicts of not guilty were entered by a previous court in the late 1990’s when similar offences had been alleged.

R v K, Court of Appeal, 2008 - Section 18 GBH

The Defendant had been convicted of intending to cause grievous bodily harm. Counsel was not instructed in the trial but advised pro bono on the issue of fresh evidence.
