Oliver’s has a well-established Crown Court practice and accepts instructions across the full range of criminal law. He is regularly instructed on behalf of the defence, and increasingly for the prosecution. His work has often included multi-handed cases and factually dense trials, requiring regular engagement with large volumes of material and a careful, analytical approach to case strategy. He continues to handle a busy, demanding practice, appearing in matters beyond his level of call and delivering excellent results. This is evidenced by being appointed to the Grade 3 CPS Panel at a youthful stage and becoming an approved Rape and Serious Sexual Offences (RASSO) Advocate, together with his loyal instructions to defend.

Recently, he has appeared to prosecute in cases arising from investigations conducted by major crime teams and specialist CPS prosecution units, and he is accustomed to working on cases involving coordinated evidence from multiple sources and agencies. Operation Ethereal was a complex major crime team investigation into an international organised crime group from the Netherlands conspiring to kidnap an individual in the United Kingdom, believed to have stolen from them. Members from that organised crime group were found in an Airbnb in North Lincolnshire in possession of a live firearm with ammunition, a kidnap kit, and a paper note titled “TARGET” containing an address in Hull. 5 defendants were convicted of their involvement, and custodial sentences were passed together totalling 26 years. Oliver was instructed as the Prosecution Junior and appeared alone at the sentence, dealing with the hearing himself. He also appeared as part of the prosecution in Operation Lindrick, which was an investigation into a tattoo and piercing artist who provided scarification services, subsequently charged with s.20 wounding and pleaded guilty following a contested legal argument, together with a campaign of rape and sexual violence against many of his customers when providing intimate piercings. Oliver was recently instructed as the Defence Junior in Operation Swale, an investigation into one of the most sophisticated cannabis production conspiracies in the North East, where a commercial landlord used his properties to set up cannabis factories with an Albanian Organised Crime Group and used fake identification to register ‘ghost tenants’ for council tax to give the impression the properties were occupied, with the value of the production being over £5 million.

In addition, Oliver is often instructed in matters of high public interest, such as representing the first defendant to be sentenced in Hull following the nationwide public disorder in August 2024, as reported by the BBC here. He also receives instructions to appear at contested hearings under the Proceeds of Crime Act 2002 and has represented individuals following conviction, as well as through civil applications involving professionals such as pharmacists and doctors.
