Oliver’s criminal practice continues to develop in serious and complex litigation in the Crown Court, where he is regularly instructed on behalf of both the defence, and also the prosecution. His work often involves multi-handed cases and factually dense prosecutions, requiring regular engagement with large volumes of material and a careful, analytical approach to case strategy.

He skilfully handles a busy and demanding practice, often appearing in matters above his level of call and delivering excellent results. This is evidenced by being appointed to the Grade 3 CPS Panel at a youthful call and becoming an approved Rape and Serious Sexual Offences (RASSO) Advocate, together with loyal defence instructions.

Recently, he has frequently dealt with instructions arising from investigations conducted by major crime teams and specialist prosecution units, and he is accustomed to working within those cases that involve 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 passed together totalling 26 years. Oliver appeared as the Prosecution Junior alone at the sentence and dealt with hearing himself.

Notably, Oliver 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 also a Led 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 to this, Oliver is often instructed in matters attracting a high degree of public interest, such as representing the first defendant to be sentenced in Hull following the large scale nationwide public disorder that took place in August 2024, reported by the BBC here. He also receives instructions to appear at contested hearings relating to the Proceeds of Crime Act 2002 and has represented individuals following conviction and also through civil applications involving professionals such as pharmacists and doctors.
