Crown Court & appeals

Sexual Offences and cases involving pre-recorded evidence

With the increasing use of pre-recorded evidence, sometimes months before the trial takes place, Oliver understands the importance of scrupulous case preparation.  He regards an early conference with his client as essential so that he can identify the issues, take detailed instructions and advise on any lines of enquiry long before any questioning of witnesses. With the limitations now placed on advocates when cross examining witnesses, especially children, Oliver is proficient at knowing how to frame questions to elicit the desired answer whilst keeping within the rules. He is on the specialist Rape and Serious Sexual Offence Panel and receives regular training and updates on prosecuting and defending sensitive cases involving sexual allegations. He also contributes to the training of police officers in this area.

In cases involving allegations of possession and distribution of indecent material, Oliver is adept at identifying any flaws in the technical evidence. He uses a panel of experts to assist him and maintains a good working relationship with the police digital forensic unit so that he is often able to achieve a positive outcome for his client.


Drugs supply

Rarely is a suspect caught “red handed” in these cases. Typically the police rely on the inference to be drawn from a combination of surveillance, ANPR, cell site location data and phone extraction evidence. Having prosecuted a number of high profile county lines drugs cases, Oliver is accomplished at presenting this highly technical evidence in a way that can be followed by a jury. Equally, when defending a suspect accused of drugs supply, he is able to spot any holes in the prosecution case.


Modern Slavery

Oliver has successfully argued this defence for several clients, including the first such case in North Wales. He is familiar with the referral mechanism and procedure for how cases are assessed by the National Crime Agency and has assisted solicitors and barristers locally on the process.



Oliver defended his first murder in 2008, when he persuaded the prosecution to accept a plea to causing ABH. Since then, he has prosecuted and defended cases ranging from murder and wounding with intent through to common assault. His detailed knowledge of statutory defences and case law in this area enables him to quickly identify the issue and advise his clients. He also has an appreciation and understanding of more complex issues such as causation and mechanism of injury. He has achieved a successful result for his clients in a number of cases by exposing inconsistencies between the witnesses’ explanation for the injury and the medical/scientific evidence.
